Methods for low atomization and odorless catalyst to improve indoor air quality

2月 10th, 2025 News

Introduction

With the acceleration of urbanization and the improvement of people’s quality of life, indoor air quality issues have attracted increasing attention. According to statistics from the World Health Organization (WHO), about 90% of the world’s population lives in an environment with excessive air pollution, and indoor air pollution is particularly harmful to health. Studies have shown that long-term exposure to low-quality indoor air can cause a variety of respiratory diseases, cardiovascular diseases, and even increase the risk of cancer. Therefore, improving indoor air quality has become an important issue in protecting public health.

Among many air purification technologies, catalyst technology has gradually become a hot topic for research and application due to its efficient, environmentally friendly and sustainable characteristics. In particular, low atomization and odorless catalysts have significant advantages as a new type of air purification material. Low atomization and odorless catalysts can not only effectively remove harmful substances in the air without secondary pollution, but also keep the indoor environment fresh and comfortable. Its working principle is to convert harmful gases (such as formaldehyde, VOCs, etc.) in the air into harmless substances through catalytic reactions, thereby achieving the purpose of purifying the air.

This article aims to deeply explore the application of low atomization odorless catalysts in improving indoor air quality, combine new research results and technical progress at home and abroad, analyze their working principles, product parameters, and application scenarios in detail, and propose future developments Direction and challenge. The article will ensure the scientificity and authority of the content by citing a large number of authoritative foreign documents and famous domestic documents, and provide readers with a comprehensive and systematic reference.

The working principle of low atomization odorless catalyst

The low atomization odorless catalyst is an air purification material based on nanotechnology and porous materials. Its core mechanism of action lies in catalytic oxidation reaction. The catalyst decomposes these harmful substances into harmless water and carbon dioxide by adsorbing harmful gas molecules in the air, such as formaldehyde, VOCs (volatile organic compounds), and then undergoes a redox reaction on its surface. This process can not only effectively remove pollutants in the air, but also avoid the secondary pollution problems that traditional air purification methods may bring.

1. Composition and structure of catalyst

The low atomization odorless catalyst is usually composed of active metal oxides, noble metals, carbon-based materials or composite materials. Common active ingredients include titanium dioxide (TiO?), manganese dioxide (MnO?), zinc oxide (ZnO), etc. These materials have high specific surface area and excellent photocatalytic properties. In addition, in order to improve the stability and catalytic efficiency of the catalyst, the researchers also introduced precious metals (such as platinum, palladium, gold, etc.) as cocatalysts to further enhance their catalytic activity.

The microstructure of the catalyst has a crucial impact on its performance. Low atomization odorless catalysts are usually designed with porous structures to increase their specific surface area and thus improve their adsorption capacity to harmful gases. Studies have shown that factors such as the pore size, porosity, and pore distribution of the catalyst will affect its catalytic effect. For example, nanoscale pore sizes can significantly improve the adsorption capacity and reaction rate of the catalyst, while micron-scale pore sizes help diffusion and transport of gas.

2. Mechanism of catalytic reaction

The main working principle of low atomization odorless catalyst is to promote the redox reaction of harmful gases in the air through photocatalytic or thermal catalysis. Taking titanium dioxide as an example, when it is exposed to ultraviolet rays, an electron-hole pair will be generated. These electrons and holes migrate to the catalyst surface, react with oxygen and water molecules adsorbed thereto, and form a strong oxidative Hydroxy radicals (·OH) and superoxide anion radicals (O??). These free radicals have extremely strong oxidation capacity and can quickly oxidize formaldehyde and other organic pollutants into harmless water and carbon dioxide.

In addition to photocatalytic reactions, low atomization and odorless catalysts can also function through thermal catalytic methods. Under normal temperature or low temperature conditions, the active sites on the catalyst surface can adsorb harmful gas molecules in the air and convert them into harmless substances through the breakage and recombination of chemical bonds. This thermal catalytic reaction does not require an external light source and is therefore suitable for indoor environments under various lighting conditions.

3. Odorless and low atomization characteristics

Another important feature of low atomization odorless catalyst is its odorless and low atomization properties. Traditional air purification materials may release odors or form visible atomization during use, causing discomfort to users. The low-atomization and odorless catalyst effectively solves this problem by optimizing the material formulation and preparation process. Specifically, after special treatment of the active ingredients in the catalyst, the release of volatile organic matter can be reduced while maintaining high-efficiency catalytic properties and avoiding the generation of odors. In addition, the particle size of the catalyst is controlled at the nanoscale so that it does not form obvious atomization during use, and keeps the indoor environment clean and beautiful.

4. Environmental protection and sustainability

Low atomization and odorless catalyst not only has high efficiency air purification capabilities, but also has good environmental protection and sustainability. First of all, the catalyst itself is made of natural minerals or renewable materials, and does not produce harmful waste during the production process, which is in line with the concept of green chemistry. Secondly, the catalyst has a long service life and can usually last for a fewYears or even longer, reducing the need for frequent replacement and reducing resource consumption. After that, the catalyst will not produce secondary pollution during use, avoiding environmental problems that may be caused by traditional air purification methods.

Product parameters and performance indicators

In order to better understand the performance characteristics of low atomization odorless catalysts, the following are some key product parameters and performance indicators of this type of catalyst. These data not only reflect the technical level of the catalyst, but also provide users with a basis for selection and use.

1. Active ingredients and loading

Active Ingredients Load (wt%) Main Functions
TiO2(TiO?) 5-10 Photocatalytic oxidation, degradation of organic pollutants
Manganese dioxide (MnO?) 3-5 Thermal catalytic oxidation, removing formaldehyde, etc.
Zinc oxide (ZnO) 2-4 Room temperature catalysis, degradation of VOCs
Platinum (Pt) 0.5-1 Improve catalytic activity and enhance stability
Palladium (Pd) 0.3-0.5 Improve catalytic activity and enhance anti-toxicity

2. Specific surface area and pore size distribution

parameters value Unit
Specific surface area 100-300 m²/g
Average aperture 5-20 nm
Pore volume 0.1-0.3 cm³/g

The larger the specific surface area of ??the catalyst, the stronger its adsorption capacity and the higher the efficiency of the catalytic reaction. Studies have shown that nano-scale pore sizes can significantly improve the adsorption capacity and reaction rate of the catalyst, while micron-scale pore sizes help diffusion and transport of gas. Therefore, an ideal catalyst should have a large specific surface area and a reasonable pore size distribution to achieve an optimal catalytic effect.

3. Catalytic activity and reaction rate

Reactants Reaction rate constant (k) Unit References
Formaldehyde 0.05-0.1 min?¹ [1] Zhang et al., 2020
0.03-0.06 min?¹ [2] Kim et al., 2018
A 0.02-0.04 min?¹ [3] Li et al., 2019
Acetaldehyde 0.04-0.07 min?¹ [4] Wang et al., 2021

The catalytic activity of a catalyst is usually expressed by the reaction rate constant (k). The larger the value, the faster the reaction rate of the catalyst and the better the purification effect. The reaction rates of different types of harmful gases vary on the catalyst surface, depending on the chemical properties of the gas and the active site of the catalyst. By modifying and optimizing the catalyst, its catalytic activity against specific pollutants can be further improved.

4. Stability and durability

Anti-poisoning ability 100 ppm SO?, 24 hours Activity recovery is more than 90% [7] Liu et al., 2019

The stability and durability of catalysts are important indicators for measuring their actual application value. Studies have shown that low atomization odorless catalysts can still maintain high catalytic activity in high temperature, high humidity and environments containing interfering substances (such as SO?, NO?, etc.), and show good stability and durability. In addition, the catalyst can restore its original catalytic properties through simple regeneration treatment (such as heating or light) and extend its service life.

The low atomization odorless catalyst will not release odors or form obvious atomization during use, which is a major advantage compared to other air purification materials. By optimizing the catalyst formulation and preparation process, the release of volatile organic matter can be effectively controlled to ensure the freshness and comfort of the indoor environment.

Breakthrough of low atomization and odorless catalysts in textile processing

2月 10th, 2025 News

The background and significance of low atomization and odorless catalyst

With the rapid development of the global textile industry, environmental protection and sustainability have become the core issues of concern to the industry. In traditional textile treatment processes, the use of chemical additives may not only lead to environmental pollution, but may also have adverse effects on workers’ health. Especially in the printing and dyeing, coating, waterproofing and other processes, the catalysts and additives used in large quantities often have volatile organic compounds (VOCs) and odors. These substances are not only harmful to the environment, but also reduce production efficiency and product quality. Therefore, developing a low-atomization and odorless catalyst has become a key issue that needs to be solved in the textile industry.

In recent years, domestic and foreign scholars and enterprises have invested a lot of resources to develop new catalysts to replace traditional high-pollution and high-energy consumption chemicals. As an innovative solution, low atomization and odorless catalysts are gradually emerging in the field of textile processing. This type of catalyst can not only effectively reduce the emission of volatile organic matter, but also significantly improve the performance of textiles, such as durability, softness, wrinkle resistance, etc. More importantly, it can significantly reduce the negative impact on the environment and human health without affecting production efficiency, which is in line with the modern society’s pursuit of green manufacturing.

This article will conduct in-depth discussion on the application breakthroughs of low-atomization odorless catalysts in textile processing, analyze their technical principles, product parameters, and market prospects, and combine relevant domestic and foreign literature to fully display new progress in this field. Through a review of existing research, this article aims to provide readers with a systematic and comprehensive perspective to help understand the importance of low atomization odorless catalysts in the textile industry and their future development direction.

Technical principles of low atomization and odorless catalyst

The core advantage of low atomization odorless catalyst is its unique molecular structure design and reaction mechanism, which allows it to significantly reduce volatility and odor generation while maintaining efficient catalytic properties. Specifically, this catalyst mainly achieves technological breakthroughs through the following aspects:

1. Molecular structure optimization

Traditional catalysts usually contain a large amount of organic solvents and additives. These components are prone to volatilization under high temperature or high pressure conditions, forming atomization phenomenon and releasing a pungent odor. The low-atomization and odorless catalyst adopts a special molecular structure design, reducing the content of volatile components. For example, by introducing large molecular weight polymers or nanomaterials, the researchers enhanced the stability of the catalyst, making it difficult to decompose at high temperatures, thereby effectively inhibiting the production of volatile organic matter.

In addition, the low atomization odorless catalyst also improves its adhesion to the textile surface by adjusting the length and branch structure of the molecular chain. This means that the catalyst can be distributed more evenly on the fibers, reducing the need for excessive use and further reducing VOCs emissions. Research shows that this optimized molecular structure not only improves the stability of the catalyst, but also enhances its catalytic activity, making the textile processing process more efficient.

2. Reaction mechanism innovation

Another key technological breakthrough in low atomization odorless catalysts is the innovation of their reaction mechanisms. Conventional catalysts usually rely on alkaline reactions or redox reactions to promote chemical treatment of textiles, but these reactions are often accompanied by a large number of by-products, resulting in an increase in odor and volatile substances. In contrast, low atomization odorless catalysts adopt more mild reaction paths, such as photocatalysis, enzyme catalysis, or metal organic framework (MOF) catalysis.

Among them, photocatalysis is a new catalytic technology that has attracted much attention. By introducing photosensitive materials such as titanium dioxide (TiO?) or carbon nitride (g-C?N?), the catalyst can activate specific chemical reactions under ultraviolet or visible light, thereby achieving efficient textile processing. The advantage of photocatalysis is that it does not require high temperature or high pressure conditions, the reaction process is relatively mild, and there are almost no volatile by-products. In addition, photocatalysis can also be combined with other catalytic mechanisms to further improve the reaction efficiency.

Enzyme catalysis is another innovative reaction mechanism. As a biocatalyst, enzymes are highly selective and specific, and can efficiently catalyse complex chemical reactions under normal temperature and pressure. Researchers have successfully developed a series of enzyme catalysts suitable for textile processing by screening and modifying specific enzymes, such as lipase, catalase, etc. These enzyme catalysts not only have excellent catalytic properties, but also have good biodegradability and will not cause pollution to the environment. More importantly, there is almost no odor generated during the enzyme catalysis process, making the textile processing process more environmentally friendly.

Metal organic frame (MOF) catalysis is a new catalytic technology that has emerged in recent years. MOF materials have a highly ordered pore structure and adjustable chemical properties, which can effectively adsorb and activate reactants, thereby improving catalytic efficiency. Research shows that MOF catalysts show excellent performance in textile processing, especially in processes such as dyeing, coating and waterproofing, which can significantly improve the quality of the product. In addition, the porous structure of the MOF material can effectively adsorb volatile organic matter, further reducing the emission of VOCs.

3. Environmentally friendly formula

In addition to molecular structure optimization and reaction mechanism innovation, low atomization odorless catalystIt also adopts an environmentally friendly formula design. Traditional catalysts usually contain a large amount of organic solvents and additives, which are not only harmful to the environment, but may also have adverse effects on human health. To this end, the researchers developed a series of green catalysts by introducing aqueous systems, natural plant extracts and other environmentally friendly additives.

Aqueous system is one of the commonly used environmentally friendly formulas. Compared with traditional organic solvents, aqueous systems have lower volatility and higher safety, and can significantly reduce VOCs emissions without sacrificing catalytic properties. Studies have shown that aqueous catalysts exhibit excellent properties in textile treatment, especially in dyeing and coating processes, which can significantly improve the durability and softness of the product.

Natural plant extracts are also one of the environmentally friendly additives that have attracted much attention in recent years. Researchers have developed a series of natural catalysts by extracting active ingredients in plants, such as tannins, flavonoids, etc. These catalysts not only have good catalytic properties, but also have excellent antibacterial, anti-mold and anti-oxidant functions, which can provide additional protection during textile processing. In addition, natural plant extracts are also good biodegradable and will not cause pollution to the environment.

Other environmentally friendly additives include inorganic nanomaterials, bio-based polymers, etc. These additives can not only improve the stability and catalytic performance of the catalyst, but also impart more functionality to textiles, such as antibacterial, ultraviolet, anti-static, etc. Research shows that low atomization and odorless catalysts using environmentally friendly formulas show excellent comprehensive performance in textile treatment, which not only meets environmental protection requirements but also increases the added value of the product.

The coated cotton fabric has excellent wind resistance and soft feel, and it still maintains good wind resistance after multiple washes. In addition, due to the good environmental protection of water-based catalysts, the cost of wastewater treatment has also been significantly reduced, and the overall economic benefits of the enterprise have been improved.

3. Application in waterproofing process

Waterproof treatment is an important part of the functional treatment of textiles and is widely used in outdoor clothing, tents, raincoats and other fields.

The fit between low atomization and odorless catalysts and environmental regulations

2月 10th, 2025 News

The background and importance of low atomization odorless catalyst

With the continuous improvement of global environmental awareness, all industries have paid more and more attention to the research and development and application of environmentally friendly products. As a key material in many fields such as chemical industry, energy, and automobiles, the performance and environmental protection characteristics of the catalyst are directly related to the efficiency of the production process and its impact on the environment. Traditional catalysts often have problems such as severe atomization and pungent odor, which not only affects the health of the operators, but may also cause pollution to the surrounding environment. Therefore, the development of low atomization odorless catalysts has become one of the hot topics of current research.

Low atomization odorless catalyst refers to a type of catalyst that has almost no atomization phenomenon during use and has no obvious odor. The emergence of such catalysts not only solves many problems brought about by traditional catalysts during use, but also provides new solutions for industrial production and environmental protection. The low-atomization and odorless catalyst has a wide range of applications, covering multiple fields such as petrochemicals, coatings, adhesives, and automotive exhaust treatment. Especially today, with increasingly strict environmental regulations, the market demand for low-atomization and odorless catalysts is gradually increasing, becoming one of the important means for enterprises to achieve green production.

This article will discuss the fit between low-atomization odorless catalysts and environmental protection regulations from multiple angles, analyze their application prospects in different industries, and combine relevant domestic and foreign literature to deeply explore the technical characteristics and product parameters of this type of catalysts. and its positive impact on the environment. The article will also list the main technical indicators of low-atomizing odorless catalysts in detail through tables so that readers can better understand their performance advantages. In addition, this article will also quote a number of authoritative foreign documents, combine the research results of famous domestic literature to fully demonstrate the application value and development potential of low-atomization and odorless catalysts in the field of environmental protection.

Technical principles of low atomization and odorless catalyst

The reason why low atomization and odorless catalysts can reduce atomization and eliminate odor during use is mainly due to their unique chemical structure and physical characteristics. In order to better understand the working principle of this type of catalyst, we need to conduct in-depth discussions on its molecular structure, surfactivity, reaction mechanism, etc.

1. Molecular Structure Design

The molecular structure of low atomization odorless catalysts is usually carefully designed to ensure good stability and reactivity during use. Common low atomization and odorless catalysts include organometallic compounds, nanoparticle catalysts, polymer catalysts, etc. The molecular structure of these catalysts usually contains specific functional groups, such as hydroxyl (-OH), carboxyl (-COOH), amine (-NH2), etc. These groups can selectively adsorption with reactants, thereby improving catalysis efficiency. In addition, the molecular weight and molecular shape of the catalyst also have an important influence on its atomization performance. Studies have shown that catalysts with larger molecular weight can reduce the occurrence of atomization to a certain extent due to their higher viscosity and lower volatility.

2. Surfactivity and dispersion

The surfactivity of a catalyst is one of the key factors that determine its catalytic properties. Low atomization odorless catalysts usually have high surfactivity and can be evenly dispersed in the reaction system to form a stable catalytic layer. This uniform dispersion property not only helps to improve catalytic efficiency, but also effectively reduces the atomization phenomenon caused by the catalyst during use. Studies have shown that nanoscale catalysts can significantly improve surface activity due to their large specific surface area and small particle size, thereby reducing atomization while maintaining excellent catalytic performance.

In addition, surface modification of catalysts is also one of the important means to reduce atomization. By modifying the catalyst surface, its surface properties can be changed, its interaction with reactants can be enhanced, thereby improving catalytic efficiency and reducing atomization. For example, the researchers successfully reduced the tendency of the catalyst to atomize in liquid media by introducing hydrophilic or hydrophobic groups on the catalyst surface.

3. Reaction mechanism and thermal stability

The reaction mechanism of low atomization odorless catalyst is closely related to its thermal stability. In high temperature environments, the thermal stability of the catalyst determines whether it will decompose or volatilize, which will affect its atomization performance. To improve the thermal stability of the catalyst, researchers usually use a variety of methods, such as doping other metal elements, introducing high-temperature-resistant support materials, etc. These measures can not only enhance the thermal stability of the catalyst, but also effectively prevent it from decomposing or volatilizing at high temperatures, thereby reducing the occurrence of atomization.

In addition, the reaction mechanism of the catalyst also has an important impact on its atomization performance. Studies have shown that some catalysts produce intermediate products or by-products during the reaction, which may cause changes in the catalyst surface, which in turn affects its atomization performance. Therefore, optimizing the reaction mechanism of the catalyst and reducing the generation of by-products is also one of the important ways to reduce atomization.

4. Control of Volatile Organic Compounds (VOCs)

An important feature of low atomization odorless catalyst is its effective control of volatile organic compounds (VOCs). VOCs are a class of easily volatile organic compounds that can cause harm to human health and the environment when they spread in the air. Traditional catalysts often release large amounts of VOCs during use, while low atomization and odorlessness are stimulated.The agent significantly reduces the emission of VOCs by improving the molecular structure and reaction mechanism. Research shows that some low atomization odorless catalysts can reduce the emission of VOCs to 1/10 or even lower than traditional catalysts, thereby greatly reducing environmental pollution.

Product parameters of low atomization odorless catalyst

In order to more intuitively demonstrate the technical characteristics and performance advantages of low atomization odorless catalysts, this article will list its main product parameters in a table. The following table summarizes the technical indicators of several common low-atomization and odorless catalysts on the market, including key parameters such as catalyst type, chemical composition, appearance morphology, atomization rate, VOCs emissions, thermal stability, etc.

Catalytic Type Chemical composition Appearance shape Atomization rate (%) VOCs emissions (mg/L) Thermal Stability (?) Applicable temperature range (?) Applicable fields
Organometal Catalyst Rubsonium, palladium, platinum Solid Powder < 0.5 < 10 300 – 500 200 – 400 Petrochemical, automotive exhaust treatment
Nanoparticle Catalyst TiO?, ZnO Nano powder < 0.3 < 5 400 – 600 150 – 500 Coatings, adhesives, air purification
Polymer Catalyst Polyurethane, polyamide Liquid < 0.1 < 2 200 – 300 100 – 300 Coating, adhesive, plastic processing
Biomass Catalyst Plant Extract Solid Particles < 0.2 < 8 250 – 400 150 – 350 Agricultural waste treatment, biofuel production
Inorganic salt catalyst Sulphur copper, nitr silver Solid Powder < 0.4 < 15 350 – 550 200 – 500 Water treatment, waste gas treatment

From the above table, it can be seen that different types of low atomization odorless catalysts have differences in chemical composition, appearance morphology, atomization rate, VOCs emissions, thermal stability, etc. Among them, nanoparticle catalysts and polymer catalysts exhibit lower atomization rate and VOCs emissions due to their unique molecular structure and surfactivity, which are suitable for areas with high environmental protection requirements; while organic metal catalysts and inorganic salt catalysts Because of its high thermal stability and wide applicable temperature range, it is often used in catalytic reactions in high temperature environments.

The position of low atomization and odorless catalysts in environmental protection regulations

As the global environmental awareness increases, governments across the country have issued a series of strict environmental protection regulations aimed at reducing the negative impact of industrial production on the environment. As an environmentally friendly catalyst, low-atomization and odorless catalysts have become increasingly prominent in environmental protection regulations and have become an important tool for enterprises to achieve green production. Here are several key points of low atomization and odorless catalysts in environmental regulations:

1. Meet VOCs emission reduction requirements

Volatile organic compounds (VOCs) are one of the main sources of air pollution, and many countries and regions have formulated strict VOCs emission standards. For example, the EU’s Industrial Emissions Directive (IED) stipulates that industrial enterprises must take effective measures to reduce VOCs emissions to ensure that their emissions do not exceed the specified limit. The U.S. Environmental Protection Agency (EPA) also clearly stipulates VOCs emission standards in the Clean Air Act and requires companies to use raw materials and processes with low VOCs emissions during production.

Low atomization odorless catalysts can significantly reduce VOCs emissions in industrial production due to their effective control of VOCs, helping enterprises easily meet the requirements of environmental protection regulations. Research shows that companies using low atomization odorless catalysts can reduce VOCs emissions to 1/10 or even lower than traditional catalysts, thus greatly reducing pollution to the atmospheric environment.

2. Reduce PM2.5 and PM10 emissions

Fine particulate matter (PM2.5) and inhalable particulate matter (PM10) are important components of air pollution. Long-term exposure to high concentrations of PM2.5 and PM10 environments will have serious impacts on human health. Therefore, many countries and regions have introduced strict PM2.5 and PM10 emission standards. For example, China’s “Action Plan for Air Pollution Prevention and Control” requires that by 2025, the national PM2.5 concentration will drop by more than 18%, and the PM2.5 concentration in key areas will drop by more than 25%.

The low atomization odorless catalyst has almost no atomization phenomenon during use, so it can effectively reduce the emissions of PM2.5 and PM10. Research shows that enterprises using low atomization odorless catalysts can reduce their PM2.5 and PM10 emissions to 1/5 or even lower than traditional catalysts, thereby significantly improving air quality and protecting public health.

3. Comply with the regulations on the management of hazardous chemicals

Many traditional catalysts are hazardous chemicals, and they have certain safety hazards during production, storage and transportation. In order to ensure public safety, governments have formulated strict regulations on the management of hazardous chemicals. For example, the EU’s Chemical Registration, Evaluation, Authorization and Restriction Regulations (REACH) stipulates that all chemicals entering the EU market must be registered and subject to strict safety assessments. The US’s Toxic Substance ControlThe TSCA also strictly regulates the production, use and import and export of chemicals.

Due to its non-toxic, harmless and odorless characteristics, low-atomization and odorless catalysts meet the requirements of hazardous chemical management regulations and can effectively reduce the safety risks of enterprises. Research shows that low atomization and odorless catalysts will not cause harm to human health and the environment during use, so they are widely used in chemical industry, energy, automobiles and other fields.

4. Support circular economy and sustainable development

Circular economy and sustainable development are important trends in the development of global economic today. Many countries and regions have introduced relevant policies to encourage enterprises to adopt environmentally friendly materials and technologies to promote the recycling of resources and energy conservation and emission reduction. For example, China’s “Circular Economy Promotion Law” stipulates that enterprises should give priority to the use of renewable resources and environmentally friendly materials to reduce resource waste and environmental pollution.

As an environmentally friendly catalyst, low atomization and odorless catalyst can not only reduce pollutant emissions in industrial production, but also improve resource utilization efficiency and support circular economy and sustainable development. Research shows that enterprises using low atomization odorless catalysts can improve their production efficiency by 10%-20%, and energy consumption and raw material consumption can also be significantly reduced, thus achieving a win-win situation of economic and environmental benefits.
