2月 10th, 2025 News

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.

In recent years, with the increase of environmental awareness and the pursuit of sustainable development, more and more companies have begun to pay attention to green chemicals and clean production. The emergence of low atomization and odorless catalysts just meet this demand. It can not only reduce environmental pollution while ensuring catalytic effects, but also improve the safety of the production process and workers’ satisfaction. Therefore, the application prospects of low-atomization and odorless catalysts are very broad, especially in the fields of fine chemicals, pharmaceutical manufacturing, food processing, etc., whose advantages are particularly obvious.

This article will discuss in detail the reasons for the selection of low-atomization odorless catalysts and their actual effects, combine new research results and application cases at home and abroad, analyze their performance in different industries, and use specific product parameters and experimental data, Further verify its superiority. The article will also cite a large number of foreign documents and famous domestic documents to provide readers with comprehensive and in-depth reference.

Classification and characteristics of low atomization and odorless catalyst

Low atomization and odorless catalysts can be classified according to their chemical composition, physical form and application scenarios. Depending on the chemical composition, low atomization and odorless catalysts are mainly divided into three categories: metal catalysts, organic catalysts and heterogeneous catalysts. Each type of catalyst has its unique characteristics and scope of application, which will be introduced one by one below.

1. Metal Catalyst

Metal catalysts are one of the catalysts that have been widely used for a long time, with high activity, high selectivity and good stability. Common metal catalysts include precious metals (such as platinum, palladium, gold) and transition metals (such as iron, cobalt, nickel). These metal catalysts are usually present in the form of nanoparticles or films, enabling efficient catalytic reactions at lower temperatures. However, traditional metal catalysts are prone to atomization under high temperature or high pressure conditions, resulting in catalyst loss and environmental pollution. To overcome this problem, the researchers developed a series of low-atomization metal catalysts.

Features:

  • High activity: Metal catalysts have excellent catalytic properties and can maintain high efficiency over a wide temperature range.
  • High selectivity: By adjusting the type and load of metal, selective control of a specific reaction path can be achieved.
  • Good thermal stability: The specially treated metal catalyst can remain stable under high temperature conditions and reduce the occurrence of atomization.
  • No odor: The metal itself is not volatile, so it does not produce odor.

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.
