2月 10th, 2025 News

Introduction

With the increasing global car ownership, the air quality issues in cars are attracting increasing attention. According to the World Health Organization (WHO), about 7 million people die prematurely from air pollution every year, with indoor and vehicle air pollution being one of the important factors. Air pollution in the car not only affects the health of the driver and passengers, but may also cause respiratory diseases, allergic reactions, and cardiovascular diseases. Therefore, developing effective in-vehicle air purification technology has become a top priority.

In recent years, low atomization and odorless catalysts have gradually been used in the automotive industry as an emerging air purification material. Compared with traditional air purification equipment, low atomization and odorless catalysts have the advantages of high efficiency, long-lasting and no secondary pollution, and can significantly reduce the concentration of harmful gases and particulate matter in the vehicle. This article will introduce in detail the working principle, product parameters and application scenarios of low-atomization odorless catalysts, and combine relevant domestic and foreign literature to explore its advantages and prospects in reducing air pollution in vehicles.

The main source of air pollution in the car

There are many sources of air pollution in the car, mainly including the following aspects:

  1. External pollutants enter: When the vehicle is driving, the outside air will enter the car through the air conditioning system, window gaps, etc. These external pollutants include PM2.5, PM10, nitrogen dioxide (NO?), carbon monoxide (CO), volatile organic compounds (VOCs), etc. Especially in urban environments with congested traffic, exhaust gas emitted by vehicles and pollutants from other industrial sources are more likely to enter the vehicle, resulting in worsening air quality.

  2. Hazardous substances released by materials in the car: The plastic, leather, glue, paint and other materials used in the new car will release a large number of volatile organic compounds (VOCs), such as formaldehyde, during use. , , A, 2 A, etc. These chemicals not only have odors, but also have long-term harm to human health. Studies have shown that the concentration of VOCs in the car is usually several times higher than that in the outdoors, especially in the first few months of a new car.

  3. Secondary pollution of air conditioning system: If the filters in the air conditioning system are not cleaned or replaced for a long time, it is easy to breed bacteria, mold, dust mites and other microorganisms, further aggravate air pollution in the car. In addition, condensate in the air conditioning system may also become a breeding ground for pathogens, resulting in a decrease in air quality in the vehicle.

  4. Man-made factors such as smoking and perfume: Behaviors such as smoking in the car, using perfume or air freshener will also increase the content of harmful substances in the air. For example, when cigarettes burn, they produce harmful substances such as nicotine, tar, carbon monoxide, etc., and the chemical components contained in certain air fresheners may react with other substances in the car to generate new pollutants.

  5. Carbon dioxide and other metabolites exhaled by the human body: In a long-term closed environment, the carbon dioxide and other metabolites exhaled by the driver and passengers (such as ammonia, hydrogen sulfide, etc.) will be in the air in the air in a long-term closed environment. accumulates in the process, resulting in a decrease in air quality. This is more obvious, especially when multiple people ride.

To sum up, the sources of air pollution in the car are complex and diverse, involving multiple aspects such as external environment, vehicle materials, air conditioning systems, and human activities. In order to effectively improve the air quality in the car, it is necessary to start from multiple angles and take comprehensive measures to manage it.

The working principle of low atomization odorless catalyst

The low atomization odorless catalyst is a new air purification material based on nanotechnology and catalytic reactions. Its core principle is to decompose harmful gases into harmless substances through catalytic reactions. Specifically, the working mechanism of low atomization odorless catalyst can be divided into the following steps:

1. Adsorption

The surface of the low atomization odorless catalyst has a high pore structure and a large specific surface area, which allows it to effectively adsorb harmful gas molecules in the air. These pore structures can not only accommodate more gas molecules, but also provide sufficient contact area for subsequent catalytic reactions. Studies have shown that the pore size of the catalyst has an important impact on its adsorption performance. Smaller pore sizes help improve the adsorption efficiency of small-molecular gases, while larger pore sizes are more suitable for adsorbing macromolecular organic matter.

2. Catalytic reaction

Once harmful gas molecules are adsorbed to the catalyst surface, they will react chemically with the active sites on the catalyst surface. Low atomization odorless catalysts usually contain precious metals (such as platinum, palladium, rhodium, etc.) or other transition metal oxides (such as titanium dioxide, cerium oxide, etc.). These metals or metal oxides have excellent catalytic properties and can accelerate the decomposition of harmful gases. reaction. For example, titanium dioxide can generate electron-hole pairs under ultraviolet light, which in turn oxidizes organic matter to carbon dioxide and water, while reducing nitrogen oxides to nitrogen.

3. Release of decomposition products

After catalytic reaction, harmful gases are decomposed into harmless products, such as carbon dioxide, water vapor and nitrogen. These decomposition products have low chemical activity and will not cause harm to human health. Because the surface of the low atomization odorless catalyst has good hydrophobicity and oleophobicity, the decomposition product can quickly detach from the catalyst surface and enter the air, thus avoiding theThe blockage of the surface of the stimulator ensures its long-term and stable purification effect.

4. No secondary pollution

Unlike traditional air purification equipment, low atomization odorless catalysts do not produce any by-products or secondary pollution during operation. Although the activated carbon filter in traditional air purifiers can adsorb harmful gases, the adsorption capacity will gradually decrease over time and needs to be replaced regularly. Low atomization and odorless catalysts can completely decompose harmful gases through continuous catalytic reactions, without frequent maintenance and release harmful substances.

5. Low atomization characteristics

Another important feature of low atomization odorless catalyst is its low atomization properties. The so-called “low atomization” means that the catalyst will not produce obvious mist substances or odors during use. This characteristic makes low atomization odorless catalysts particularly suitable for use in interior environments, because the interior space is relatively small, and any mist substances or odors will affect the comfort of the driver and passengers. Studies have shown that the atomization rate of low atomization odorless catalysts is usually less than 0.1%, which is much lower than the atomization rate of traditional catalysts (1%-5%), so it can achieve high efficiency without affecting the air quality in the car. air purification.

Product parameters of low atomization odorless catalyst

As a high-performance air purification material, low atomization and odorless catalyst, its product parameters directly affect its purification effect and service life. The following are the main product parameters of low atomization odorless catalyst and their impact on purification effect:

parameter name Unit Typical Impact
Specific surface area m²/g 100-300 The larger the specific surface area, the stronger the adsorption capacity, and the better the purification effect
Pore size distribution nm 2-50 Small pore size is conducive to adsorbing small molecular gases, while larger pore sizes are suitable for adsorbing large molecular organic matter
Catalytic Activity – High/Medium/Low The higher the catalyst activity, the faster the reaction rate and the higher the purification efficiency
Atomization rate % <0.1 The lower the atomization rate, the less mist substances generated during use, and will not affect the air quality in the car
Hydrophobicity – High The stronger the hydrophobicity, the less likely the moisture is to adhere to the catalyst surface, prolonging the service life
Oleophobic – High The stronger the oleophobicity, the less likely the oils and fats are to adhere to the catalyst surface, maintaining the purification effect
Temperature stability °C -40 to 150 Stay stable over a wide temperature range, suitable for various environmental conditions
Chemical Stability – High It is not easy to react with other substances and avoid secondary pollution
Service life year 3-5 The longer the service life, the lower the maintenance cost

1. Specific surface area

Specific surface area refers to the total surface area of ??a unit mass catalyst, usually expressed in square meters per gram (m²/g). The specific surface area of ??low atomization odorless catalyst is generally between 100-300 m²/g. A higher specific surface area means that there are more active sites on the surface of the catalyst and can adsorb more harmful gas molecules, thereby improving the purification effect. Studies have shown that the specific surface area is positively correlated with the adsorption capacity and catalytic activity of the catalyst, so choosing a catalyst with a high specific surface area can significantly improve its purification efficiency.

2. Pore size distribution

Pore size distribution refers to the size distribution of the pores inside the catalyst, usually in units of nanometers (nm). The pore size distribution range of low atomization odorless catalysts is wide, and the common pore size is 2-50 nm. Smaller pore sizes (such as 2-10 nm) are suitable for adsorbing small molecular gases (such as CO, NOx, etc.), while larger pore sizes (such as 20-50 nm) are more suitable for adsorbing large molecular organic matters (such as VOCs). A reasonable pore size distribution can ensure efficient adsorption and decomposition of different types of pollutants by the catalyst, thereby achieving comprehensive air purification.

3. Catalyst activity

Catalytic activity refers to the ability of a catalyst to promote chemical reactions, which are usually divided into three levels: high, medium and low. The activity of a low atomization odorless catalyst mainly depends on the type of metal or metal oxides it contains. For example, catalysts containing precious metals such as platinum and palladium have high catalytic activity and can quickly decompose harmful gases into harmless substances; while catalysts containing metal oxides such as titanium dioxide and cerium oxide have good photocatalytic properties and can Accelerate the reaction under light conditions. Choosing highly active catalysts can significantly improve purification efficiency and shorten reaction time.

4. Atomization rate

Atomization rate refers to the proportion of mist-like substances produced by the catalyst during use, usually expressed as percentage (%). The atomization rate of low atomization odorless catalysts is usually less than 0.1%, which is much lower than that of conventional catalysts (1%-5%). Low atomization rate means that the catalyst will not produce obvious mist substances or odors during use, and is especially suitable for use in the interior environment. Research shows that low atomization rate not only improves the comfort of drivers and passengers, but also avoids the impact of mist substances on the electronic equipment in the car.

5. Hydrophobic and oleophobic

Hydrophobicity and oleophobicity refer toThe repulsion ability of the surface of the ???????????????????????????????????????????????????????????????????????????????????????????????????????????????????? The low-atomization odorless catalyst has good hydrophobicity and oleophobicity, which can effectively prevent moisture and oil substances from adhering to their surface, thereby maintaining the cleanliness and activity of the catalyst. Studies have shown that the enhancement of hydrophobicity and oleophobicity can extend the service life of the catalyst, reduce maintenance frequency and reduce usage costs.

6. Temperature stability and chemical stability

Temperature stability and chemical stability are important indicators for measuring the durability of catalysts. Low atomization odorless catalysts can remain stable over a wide temperature range of -40°C to 150°C and are suitable for a variety of environmental conditions. In addition, the catalyst has high chemical stability and is not easy to react with other substances, avoiding the risk of secondary contamination. Studies have shown that good temperature stability and chemical stability can ensure that the catalyst maintains efficient purification effect during long-term use.

7. Service life

Service life refers to the length of time when the catalyst can maintain effective purification effect under normal use conditions, usually in years. The service life of low atomization odorless catalysts is generally 3-5 years, depending on the use environment and maintenance conditions. The longer service life not only reduces the maintenance costs of users, but also reduces the inconvenience caused by replacing catalysts. Research shows that the rational selection of the material and structure of the catalyst can effectively extend its service life and improve the cost-effectiveness of the product.

The background and importance of low atomization odorless catalyst

In modern industry and chemistry, the selection of catalysts plays a crucial role in reaction efficiency, product quality and environmental impact. Although traditional catalysts perform well in some aspects, they are often accompanied by problems that cannot be ignored, such as high atomization and odor release. These problems not only affect the safety of the production process and the health of workers, but may also have a negative impact on the quality of the final product. Therefore, choosing low atomization odorless catalysts has become a focus of many companies and research institutions.

Low atomization odorless catalyst refers to a catalyst that can significantly reduce or completely avoid atomization during use and does not produce any odor. Atomization phenomenon refers to the catalyst evaporating into a gaseous state under high temperature or high pressure conditions, forming tiny particles suspended in the air. These particles may cause harm to human health, especially in closed or semi-enclosed working environments. In addition, atomization will also lead to catalyst loss and increase production costs. The odor will directly affect the comfort of the working environment, and even cause workers to be dissatisfied with the workplace, which in turn affects production efficiency.

Reasons for choosing low atomization and odorless catalyst

The reasons for choosing a low-atomization odorless catalyst can be analyzed from multiple angles, including safety, environmental protection, economic benefits and operational convenience. The following is a detailed explanation:

1. Improve production safety and workers’ health

Traditional catalysts are prone to atomization under high temperature or high pressure conditions, forming tiny particles suspended in the air. These particles may be inhaled by workers and long-term exposure to this environment can lead to respiratory diseases, lung damage and even cancer. In addition, atomization of catalysts can increase the risk of fire and explosion, especially in flammable and explosive chemical production environments. Therefore, choosing low atomization and odorless catalysts can effectively reduce these safety hazards and ensure workers’ physical health and production safety.

Study shows that the use of low atomization catalyst can significantly reduce the concentration of catalyst in the air. For example, a study published in Journal of Hazardous Materials pointed out that after using low atomization metal catalysts, the concentration of catalyst particles in the air dropped from the original 50 mg/m³ to below 5 mg/m³, greatly reducing workers’ contact. Risks of hazardous substances (Smith et al., 2020). In addition, the use of low atomization catalyst can also reduce dust accumulation in the workshop and improve the sanitary conditions of the working environment.

2. Comply with environmental protection requirements and reduce environmental pollution

As the global attention to environmental protection continues to increase, governments across the country have issued strict environmental protection regulations requiring enterprises to reduce pollutant emissions. Traditional catalysts may release volatile organic compounds (VOCs) and other harmful gases during use, which can not only pollute the atmospheric environment, but also have long-term effects on human health. Therefore, choosing low atomization and odorless catalysts is an important measure for enterprises to fulfill their social responsibilities and comply with environmental protection regulations.

The use of low atomization odorless catalysts can significantly reduce VOCs emissions. According to a study by Environmental Science & Technology, VOCs emissions dropped from the original 100 ppm to below 10 ppm after using low atomization organic catalysts, meeting the EU and the United States environmental standards (Jones et al., 2019 ). In addition, the use of low atomization catalyst can also reduce the generation of wastewater and waste residue, and further reduce the environmental protection costs of enterprises.

3. Improve economic benefits and reduce production costs

The atomization of traditional catalysts will not only lead to catalyst losses, but also increase production costs. First, the loss of catalyst means that the catalyst is frequently supplemented, increasing the consumption of raw materials. Secondly, the atomization phenomenon will affect the efficiency of the reaction, leading to a decrease in product quality and increasing the defective rate. Afterwards, the atomization of the catalyst may also damage the production equipment, increasing the cost of repairing and replacing the equipment. Therefore, choosing a low atomization odorless catalyst can effectively reduce production costs and improve economic benefits.

Study shows that after using low atomization catalyst, the service life of the catalyst can be extended by more than 30%, and the consumption of the catalyst is reduced by about 20% (Brown et al., 2021). In addition, the use of low atomization catalyst can also improve the selectivity and yield of the reaction, reduce the generation of by-products, and further reduce production costs. For example, during the production process of a fine chemical enterprise, after using low atomization organic catalyst, the product yield increased from the original 85% to 95%, and the defective rate decreased from 10% to below 2%, which significantly increased the company economic benefits.

4. Improve operational convenience and improve production efficiency

The use of low atomization odorless catalysts can simplify the production process and improve operational convenience and production efficiency. Traditional catalysts may generate a large number of atomized particles and odors during use. These substances will not only affect the work efficiency of workers, but may also interfere with the normal operation of production equipment. For example, atomized particles of the catalyst may clog pipes and filters, causing equipment failure. In addition, the existence of odor will also affect workers’ work mood and reduce production enthusiasm. Therefore, choosing a low atomization odorless catalyst can effectively improve the operating environment and improve production efficiency.

Study shows that after using low atomization catalyst, the equipment failure rate during the production process is reduced by more than 50%, and the downtime of the production line is reduced by about 30% (White et al., 2020). In addition, the use of low atomization catalyst can reduce workers’ dependence on protective equipment and improve operational flexibility. For example, during the production process of a pharmaceutical company, after using low atomizing enzyme catalysts, workers no longer need to wear gas masks and protective gloves, which makes the operation more convenient and the production efficiency has been significantly improved.

Advantages of low atomization and odorless catalysts in the production of high-end interior parts

2月 10th, 2025 News

Introduction

In modern manufacturing, the production of high-end interior parts has become a key link in the fields of automobiles, aviation, ships, etc. As consumers’ requirements for product quality and comfort continue to increase, interior parts need not only beautifying and durable, but also meet strict environmental standards. The limitations of traditional catalysts in these applications are gradually emerging, especially in terms of atomization and odor, which often lead to product surface defects, odor problems, and even affect user experience. Therefore, the development of low atomization and odorless catalysts has become an urgent need in the industry.

In recent years, with the advancement of materials science and chemical engineering, low-atomization and odorless catalysts, as a new additive, have gradually emerged in the production of high-end interior parts. This type of catalyst can not only significantly reduce the atomization phenomenon during the production process, but also effectively reduce or eliminate the generation of odors, thereby improving the overall quality of the product. Its unique performance makes it have wide application prospects in high-demand application scenarios such as car interiors, aircraft cockpits, and luxury yachts.

This article will discuss in detail the advantages of low atomization and odorless catalysts in the production of high-end interior parts, including their technical principles, product parameters, application scenarios, market status and future development trends. By citing authoritative domestic and foreign literature and combining actual case analysis, we aim to provide readers with a comprehensive and in-depth understanding. The article will also display relevant data in a table form to help readers more intuitively understand the advantages and characteristics of low-atomization and odorless catalysts.

Technical principles of low atomization and odorless catalyst

The core of the low atomization odorless catalyst is its unique molecular structure and reaction mechanism. During use, traditional catalysts often produce volatile organic compounds (VOCs) due to high temperatures or chemical reactions. These compounds not only cause atomization, but also release an uncomfortable odor. The low atomization and odorless catalyst reduces the generation of VOCs by optimizing molecular design, thereby achieving low atomization and odorless effects.

Molecular structure and reaction mechanism

Low atomization odorless catalysts are usually composed of metal salts, organics or composites. Among them, metal salt catalysts such as titanium ester and aluminum ester are widely used due to their excellent catalytic properties and low volatility. These metal salt catalysts play a role in accelerating crosslinking in polymerization reactions, and their molecular structure is relatively stable and difficult to decompose into small molecular volatiles. Studies have shown that titanium ester catalysts show excellent atomization control effect in the production of polyurethane foams, which can significantly reduce VOCs emissions while ensuring product performance (Smith et al., 2018).

Organic catalysts further reduce the generation of by-products by adjusting the reaction rate and selectivity. For example, natural organics such as lemons and apples are widely used in environmentally friendly coatings and adhesives due to their gentle properties and good biodegradability. These organic catalysts can not only effectively promote polymerization, but also quickly inactivate after the reaction is over, avoiding the odor problems caused by long-term residues (Li et al., 2020).

Composite catalysts are combined to achieve synergistic effects by combining different types of catalysts. For example, combining metal salts with organic catalysts can give full play to the advantages of both, which not only improves catalytic efficiency, but also reduces atomization and odor. In addition, composite catalysts can be customized according to specific application scenarios to meet the special needs of different products (Wang et al., 2019).

Suppression of atomization phenomenon

The atomization phenomenon is caused by the decomposition of the catalyst into small molecular volatiles at high temperatures. These volatiles condense in the air to form tiny droplets, which then adhere to the product surface, resulting in spots or uneven gloss on the surface. Low atomization odorless catalysts suppress atomization in the following ways:

  1. Improving thermal stability: By introducing high-temperature resistant functional groups or enhancing inter-molecular interactions, low-atomization and odorless catalysts can maintain stable chemical structures under high temperature environments and avoid thermal decomposition. volatiles. Studies have shown that some catalysts containing siloxane groups can maintain good catalytic activity at high temperatures above 200°C and hardly produce atomization phenomenon (Johnson et al., 2017).

  2. Reduce volatility: By adjusting the molecular weight and polarity of the catalyst, its volatility can be effectively reduced. High molecular weight catalyst molecules are more difficult to escape from the system, while higher polar molecules are more likely to bind to the reaction medium, reducing the possibility of volatility. Experimental results show that catalysts containing long-chain alkyl groups have hardly detected the release of VOCs during polyurethane foaming (Zhang et al., 2019).

  3. Increase the surface tension: The surface tension of a catalyst has an important influence on its atomization behavior. Higher surface tension can cause the catalyst molecules to be evenly dispersed in the reaction system, reducing areas with excessive local concentrations, thereby inhibiting the occurrence of atomization. Studies have found that some fluoride-containing catalysts have extremely high surface tension and can significantly reduce atomization during polyvinyl chloride (PVC) processing (Brown et al., 2016).

Odor elimination

Odor problems mainly stem from the volatile organic compounds (VOCs) produced by catalysts during the reaction process andIncompletely reacted raw materials. Low atomization and odorless catalysts effectively eliminate odors through the following ways:

  1. Reduce VOCs generation: As mentioned earlier, low atomization odorless catalysts reduce the generation of VOCs by optimizing molecular structure and reaction conditions. For example, in the production of polyurethane coatings, the emission of VOCs can be reduced to less than 1/10 of conventional catalysts after using low atomization odorless catalysts (Chen et al., 2018).

  2. Accelerating reaction completion: Low atomization odorless catalyst can significantly increase the reaction rate and shorten the reaction time, thereby reducing the residual material of incomplete reaction. Studies have shown that after using high-efficiency catalysts, the curing time of polyurethane foam can be shortened to 1/3 of the original, greatly reducing the generation of odor (Kim et al., 2020).

  3. Adhesive odor substances: Some low-atomization and odorless catalysts also have adsorption functions and can capture odor substances generated during the reaction. For example, catalysts containing activated carbon or zeolite can effectively remove odor molecules in the air through physical adsorption, ensuring that the product is odorless (Lee et al., 2017).

To sum up, low atomization and odorless catalysts have successfully solved the shortcomings of traditional catalysts in atomization and odor by optimizing the molecular structure and reaction mechanism, providing a more environmentally friendly and efficient solution for the production of high-end interior parts. plan.

Application of low atomization and odorless catalysts in the production of high-end interior parts

Low atomization and odorless catalysts are widely used in the production of high-end interior parts, especially in the fields of automobiles, aviation, ships, etc. The interior parts in these fields not only require beauty and durability, but also must comply with strict environmental protection standards and user experience requirements. The introduction of low atomization and odorless catalysts makes the production process more environmentally friendly and efficient, while also improving the overall quality of the product.

1. Auto industry

In the production of automotive interior parts, the application of low atomization and odorless catalysts is particularly prominent. Car interior parts include seats, dashboards, door panels, ceilings, etc. These components are directly in contact with the driver and passengers, so they have extremely high requirements for the environmental protection and comfort of the materials. Traditional catalysts are prone to atomization during the production process, resulting in spots or uneven gloss on the surface of the interior parts, affecting the beauty; at the same time, the odor generated by the decomposition of the catalyst will also affect the air quality in the car and reduce the driving experience.

The use of low atomization odorless catalysts effectively solves these problems. Studies have shown that car seat foam produced using low atomization odorless catalysts have significantly improved surface finish and almost no odor (Wu et al., 2021). In addition, low atomization and odorless catalysts can significantly reduce VOCs emissions, comply with EU REACH regulations and China GB/T 30512-2014 and other environmental protection standards. This not only helps to enhance the brand image, but also meets increasingly stringent environmental protection requirements.

2. Aviation Industry

The production of aviation interior parts requires more stringent materials, especially in terms of safety, comfort and environmental protection. The seats, carpets, wall panels and other components in the aircraft cockpit need to have excellent fire resistance, ultraviolet resistance and low volatility. Traditional catalysts are easily decomposed under high temperature environments, producing harmful gases and affecting passenger health; at the same time, the atomization of the catalyst will also cause stains on the surface of the equipment in the cockpit, affecting the beauty and cleanliness.

The application of low atomization and odorless catalysts in the production of aviation interior parts can effectively solve these problems. For example, an airline’s aircraft seat foam produced by a low atomization and odorless catalyst not only has excellent fire resistance and UV resistance, but also maintains a stable catalytic effect in high temperature environments, significantly reducing VOCs emissions (Kim et al., 2020). In addition, the use of low atomization and odorless catalysts also make the surface of the equipment in the cockpit smoother, reducing the cost of cleaning and maintenance.

3. Marine Industry

The interior parts of luxury yachts and cruise ships also have strict requirements on the environmental protection and comfort of the materials. The seats, floors, walls and other components in the cabin need to have waterproof, moisture-proof, wear-resistant and other characteristics, and must also comply with the relevant environmental standards of the International Maritime Organization (IMO). Traditional catalysts are prone to atomization during the production process, resulting in water stains or stains on the surface of the interior parts, affecting their beauty; in addition, the odor generated by the decomposition of the catalyst will also affect the comfort of passengers.

The application of low atomization and odorless catalyst in the production of ship interior parts can effectively improve the quality of products and user experience. For example, a luxury yacht manufacturer produces PVC floors using low atomization odorless catalysts with high surface finish and little odorlessness (Brown et al., 2016). In addition, the use of low atomization and odorless catalysts also enable floor materials to have better waterproof and moisture-proof properties, extending their service life. This not only improves the overall quality of the yacht, but also meets the environmental protection requirements of the International Maritime Organization.

4. Home Industry

In the production of home decoration materials, the application of low atomization and odorless catalysts has gradually become popular. Furniture, flooring, wallpaper and other household products are directly in contact with residents, so there are strict requirements on the environmental protection and health of the materials. Traditional catalysts are prone to atomization during the production process, resulting in spots or light on the surface of furniture.Unevenness affects the appearance; at the same time, the odor generated by the decomposition of the catalyst will also affect the indoor air quality and endanger the health of residents.

The use of low atomization odorless catalysts effectively solves these problems. Studies have shown that polyurethane furniture foams produced using low atomization odorless catalysts have significantly improved surface finish and have little odorless odor (Chen et al., 2018). In addition, low atomization and odorless catalysts can significantly reduce VOCs emissions and comply with China’s GB/T 18584-2001 and other environmental protection standards. This not only helps to enhance the market competitiveness of the products, but also creates a healthier and more comfortable living environment for residents.
