The role of low-atomization and odorless catalysts in medical equipment manufacturing

Definition and background of low atomization odorless catalyst

Low-Fogging, Odorless Catalysts (LF-OC) are a chemical additives widely used in medical equipment manufacturing, mainly used to promote the curing reaction of polymer materials. Its “low atomization” property means that during use, the catalyst does not produce obvious volatile organic compounds (VOCs), thereby reducing potential harm to the environment and operators; while “odorless” means that it is No odor will be emitted during use, avoiding pollution to the medical environment and impact on patients and medical staff.

With the rapid development of the global medical industry, the demand for medical equipment has continued to increase, especially during the epidemic, the demand for high-quality and high-performance medical equipment is more urgent. Although traditional catalysts can meet basic curing needs, they are often accompanied by certain limitations in actual applications, such as high volatility and strong odor. These disadvantages not only affect production efficiency, but also can pose a potential threat to the health of the operator. Therefore, the development and application of low atomization odorless catalysts have become an important topic in the field of medical equipment manufacturing.

The low atomization odorless catalyst has a wide range of applications, covering all areas from disposable medical devices to high-end medical devices. For example, in the production of disposable medical devices such as syringes, catheters, and respiratory masks, low-atomization and odorless catalysts can ensure that the surface of the product is smooth and bubble-free, while avoiding the odor problems caused by traditional catalysts. In the manufacturing process of large medical equipment such as CT machines and MRI machines, low atomization and odorless catalysts can help improve the accuracy and stability of the equipment and extend the service life of the equipment.

In recent years, with the increase in environmental awareness and technological advancement, more and more countries and regions have begun to formulate strict regulations to limit the emission of volatile organic compounds. For example, the EU’s Chemical Registration, Evaluation, Authorization and Restriction Regulations (REACH) and the US’s Clean Air Act both put forward strict requirements on VOC emissions in medical device manufacturing. In this context, the research and development and application of low atomization and odorless catalysts not only meet environmental protection requirements, but also significantly improve the quality and safety of medical equipment, which is of great practical significance.

Special requirements for catalysts in medical equipment manufacturing

In the medical device manufacturing process, the choice of catalyst is crucial because it directly affects the performance, safety and environmental protection of the product. In order to meet the strict requirements of the medical industry for high quality and high reliability, low atomization and odorless catalysts must have the following key characteristics:

1. High-efficient catalytic activity

Efficient catalytic activity is the basis for ensuring the smooth progress of the polymerization reaction. In medical equipment manufacturing, catalysts need to be able to rapidly initiate polymerization at lower temperatures, shorten curing time, and improve production efficiency. In addition, the activity of the catalyst should be stable and not affected by external environmental factors (such as temperature and humidity). Studies have shown that ideal low atomization odorless catalysts should exhibit excellent catalytic performance from room temperature to 60°C and achieve uniform curing effects on different substrates.

2. Low atomization and odorless properties

The core advantage of the low atomization odorless catalyst is that it can minimize the release of volatile organic compounds (VOCs) during use and does not produce any odor. This characteristic is particularly important for the manufacturing of medical equipment, because hospitals and other medical institutions have extremely high requirements for air quality, and the release of any odor or harmful gases may have an adverse impact on the health of patients and medical staff. According to the U.S. Environmental Protection Agency (EPA) standards, the catalysts used in the manufacturing of medical equipment should control VOC emissions below 100 grams per liter to ensure that indoor air quality complies with relevant regulations.

3. Biocompatibility and safety

Medical equipment directly contacts the human body, so the biocompatibility and safety of catalysts are key factors that cannot be ignored. Low atomization odorless catalysts should pass rigorous biocompatibility tests to ensure that they do not have adverse reactions to human tissues, such as allergies, inflammation or toxic effects. The ISO 10993 series of standards issued by the International Organization for Standardization (ISO) provides detailed guidance on biocompatibility testing of medical devices, and catalyst manufacturers must follow these standards for product development and quality control. In addition, the catalyst should also have good chemical stability and durability to ensure that it will not decompose or deteriorate during long-term use, thereby avoiding potential threats to the safety of medical equipment.

4. Environmental and sustainable

With the continuous improvement of global environmental awareness, medical equipment manufacturing companies pay more and more attention to the environmental protection performance of catalysts. Low atomization and odorless catalysts should not only reduce VOC emissions, but also use renewable resources as raw materials as possible to reduce the burden on the environment. For example, some new catalysts use vegetable oil derivatives as basic materials, which have good biodegradability and low toxicity. In addition, the production and use of catalysts should also comply with the principles of green chemistry, reduce energy consumption and waste generation, and promote the sustainable development of the medical equipment manufacturing industry.

5. Wide applicability

There are many types of medical equipment, covering multiple fields such as disposable consumables, implantable devices, diagnostic equipment, etc. Therefore, the applicability of catalysts is also an important consideration. Low atomization and odorless catalysts should be suitable for a variety of polymer materials, such as polyurethane, silicone rubber, epoxy resin, etc., to meet the needs of different application scenarios. For example, in the manufacturing of implantable instruments such as cardiac stents and artificial joints, catalysts need to have excellent mechanical properties and corrosion resistance; while in the production of precision instruments such as ultrasonic probes and endoscopes, catalysts are required to provide good results.

Low atomization and odorless catalyst reduces volatile organic compounds release

Introduction

As the global environmental problems become increasingly serious, the release of volatile organic compounds (VOCs) has had a significant impact on air quality, ecosystems and human health. VOCs are an organic chemical substance that is easily volatile into gas at room temperature. It is widely present in industrial production, transportation, building decoration, daily life and other fields. Common VOCs include, aceta, dimethyl, formaldehyde, etc. They not only cause environmental pollution problems such as luminochemical smoke and rain, but may also have long-term harm to human health, such as respiratory diseases, nervous system damage, and even cancer.

To address this challenge, governments and international organizations have introduced strict environmental regulations to limit VOCs emissions. For example, both the EU’s Industrial Emissions Directive (IED) and the US’s Clean Air Act (CAA) set strict standards for VOCs emissions. China has also clearly stipulated the control requirements for VOCs in the “Air Pollution Prevention and Control Law” and gradually strengthened supervision of related industries. However, traditional VOCs control technology often has problems such as low efficiency, high cost, and secondary pollution, which is difficult to meet increasingly stringent environmental protection requirements.

Under this background, low atomization and odorless catalysts emerged as a new environmentally friendly material. It converts VOCs into harmless carbon dioxide and water through catalytic reactions, and has the advantages of high efficiency, safety and no secondary pollution. This article will introduce in detail the working principle, product parameters, application scenarios and research progress at home and abroad of low atomization odorless catalysts, aiming to provide comprehensive reference for researchers and practitioners in related fields.

The working principle of low atomization odorless catalyst

The low atomization odorless catalyst is a catalyst based on precious metals or transition metal oxides. Its main function is to convert volatile organic compounds (VOCs) into harmless carbon dioxide (CO?) and water (H?O) through catalytic oxidation reactions ). Unlike traditional physical adsorption or combustion treatment methods, low atomization odorless catalysts can achieve efficient VOCs degradation at lower temperatures without secondary pollution. The following are the main working principles of this catalyst:

1. Catalyst selection and active sites

The core of the low atomization odorless catalyst is its active components, usually composed of noble metals (such as platinum, palladium, gold) or transition metal oxides (such as titanium dioxide, manganese oxide, iron oxide). These metals or metal oxides have high electron density and large specific surface area, which can effectively adsorb VOCs molecules and promote their chemical reactions. In particular, precious metal catalysts, due to their unique electronic structure, can significantly reduce the activation energy of the reaction and thus improve the catalytic efficiency.

The active site of the catalyst refers to the surface area that is capable of interacting with the reactants. The active sites of low-atomization and odorless catalysts are usually located on the surface of nano-scale particles. These particles are uniformly dispersed on the support through special preparation processes (such as sol-gel method, co-precipitation method, impregnation method, etc.) to form a highly dispersed Catalytic system. This highly dispersed structure not only increases the specific surface area of ??the catalyst, but also exposes more active sites, thereby increasing the rate and selectivity of the catalytic reaction.

2. Catalytic oxidation reaction mechanism

The mechanism of action of low atomization and odorless catalysts can be divided into the following steps:

  1. Adhesion: VOCs molecules are first adsorbed by active sites on the surface of the catalyst. Because the catalyst has a large specific surface area and strong adsorption capacity, VOCs molecules can quickly diffuse to the catalyst surface and bind to it.

  2. Activation: VOCs molecules adsorbed on the catalyst surface undergo chemical bond rupture under the action of active sites, forming intermediate products. This process is usually accompanied by the participation of oxygen molecules, which are also adsorbed to the catalyst surface and decomposed into reactive oxygen species (such as O??, O²?, OH·, etc.), which can further promote the oxidation reaction of VOCs.

  3. Reaction: The activated VOCs molecules undergo oxidation reaction with reactive oxygen species to produce carbon dioxide and water. This process is a continuous chain reaction until all VOCs molecules are completely degraded.

  4. Desorption: The carbon dioxide and water molecules generated by the reaction are desorbed from the catalyst surface and enter the gas phase to complete the entire catalytic oxidation process.

3. Low temperature catalytic characteristics

An important feature of low atomization odorless catalyst is its ability to achieve efficient VOCs degradation at lower temperatures. Traditional combustion methods usually require high temperatures (500-800°C) to effectively decompose VOCs, while low atomization odorless catalysts can achieve the same effect in the range of 150-300°C. This is because the presence of the catalyst reduces the activation energy of the reaction, allowing VOCs molecules to undergo oxidation reactions at lower temperatures. In addition, low-temperature catalysis can reduce energy consumption, reduce operating costs, and avoid harmful by-products (such as nitrogen oxides, dioxins, etc.) that may be generated under high temperature conditions.

4. No secondary pollution

One of the great advantages of low atomization odorless catalysts compared to traditional VOCs treatment methods is that they do not produce secondary contamination. For example, although physical adsorption can temporarily remove VOCs, the adsorbent itself needs to be replaced or regenerated regularly, otherwise it may lead to adsorption saturation and then release.The adsorbed VOCs are produced, causing secondary pollution. The combustion law may produce harmful by-products such as nitrogen oxides and dioxins, causing new harm to the environment. Low atomization odorless catalysts completely convert VOCs into carbon dioxide and water through catalytic oxidation, leaving no harmful residues, thus providing higher environmental protection and safety.

5. Atomization and odorless properties

“Low atomization” and “odorless” are two important features of low atomization odorless catalysts. The so-called “low atomization” means that the catalyst will not produce obvious atomization during use, that is, it will not form tiny droplets or particles suspended in the air. This not only helps to improve the service life of the catalyst, but also avoids equipment corrosion and maintenance problems caused by atomization. “Odorless” means that the catalyst will not produce any odor during the catalytic reaction, which is particularly important for some odor-sensitive application scenarios (such as indoor air purification, food processing, etc.).

Product parameters of low atomization odorless catalyst

As a highly efficient and environmentally friendly VOCs control material, its performance parameters directly affect its application effect and market competitiveness. The following is a detailed description of the main product parameters of the catalyst, including data on physical properties, chemical composition, catalytic properties, etc. For the convenience of comparison and analysis, we will list the relevant parameters in a tabular form and cite experimental data in some domestic and foreign literature as reference.

Future development direction and challenges

Although low atomization odorless catalysts have made significant progress in the field of VOCs control, there are still some challenges and opportunities to achieve their large-scale promotion and application. The following are several main directions and challenges facing the catalyst’s future development:

1. Improve catalytic performance

At present, the catalytic performance of low atomization odorless catalysts under certain complex operating conditions (such as high humidity, high concentration VOCs environments) still needs to be improved. Future research should focus on the following aspects:

  • Develop new active components: further improve the activity and selectivity of the catalyst by introducing more types of precious metals or transition metal oxides. For example, rare earth elements, alkaline earth metals, etc. may become new research hotspots.
  • Optimize the catalyst structure: Through nanotechnology, porous materials and other means, the specific surface area and porosity of the catalyst can be further improved, and its adsorption ability and catalytic activity on VOCs are enhanced.
  • Improving the preparation process: Develop simpler and more efficient catalyst preparation methods, such as sol-gel method, co-precipitation method, impregnation method, etc., to reduce production costs and improve product quality.

2. Enhance anti-toxicity performance

VOCs often contain toxic substances such as sulfides and chlorides. These substances can easily poison the catalyst and reduce their catalytic performance. Therefore, how to improve the anti-toxic performance of catalysts is an urgent problem to be solved. Future research can start from the following aspects:

  • Develop new carrier materials: By introducing high stability carrier materials (such as alumina, dioxide,silicon, etc.), enhancing the catalyst’s anti-toxicity ability.
  • Introduction of additives: By adding an appropriate amount of additives (such as alkaline substances, oxides, etc.), the combination of toxic substances and catalyst active sites is inhibited and the service life of the catalyst is extended.
  • Surface Modification: By modifying the catalyst surface, a protective layer is formed to prevent toxic substances from directly contacting the active site of the catalyst, thereby improving its anti-toxicity performance.

3. Reduce production costs

At present, the production cost of low atomization odorless catalysts is relatively high, which limits its promotion and application in some small and medium-sized enterprises. Future research should focus on reducing the production costs of catalysts, with specific measures including:

  • Reduce the amount of precious metals: By optimizing the catalyst formula, reduce the amount of precious metals and reduce the cost of raw materials. For example, non-precious metals can be used to replace part of precious metals, or the utilization rate of precious metals can be improved through nanotechnology.
  • Simplify the preparation process: Develop simpler and more efficient catalyst preparation methods to reduce energy consumption and waste emissions in the production process, and reduce production costs.
  • Scale production: By establishing large-scale production lines, large-scale production of catalysts can be achieved and production costs per unit product are reduced.

4. Expand application scenarios

Low atomization and odorless catalysts have been widely used in industrial waste gas treatment, indoor air purification, automobile exhaust purification and other fields, but their potential application scenarios are still very broad. Future research can explore the following new application areas:

  • Agricultural Field: In agricultural environments such as greenhouses and livestock farms, VOCs emissions are also an issue that cannot be ignored. Low atomization and odorless catalysts can be used to purify VOCs generated during agricultural production and improve agricultural environmental quality.
  • Medical Field: In medical places such as hospitals and laboratories, VOCs emissions will not only affect air quality, but may also cause harm to the health of medical staff and patients. Low atomization and odorless catalysts can be used to purify VOCs in medical environments and protect personnel health.
  • Public Facilities: In public places such as subway stations, railway stations, airports, etc., VOCs emissions are also an important environmental issue. Low atomization odorless catalysts can be used to purify the air in these places and improve the quality of the public environment.

Conclusion

As a highly efficient, safe, and secondary pollution-free VOCs control material, low atomization odorless catalyst has been widely used in many fields and has achieved significant environmental and economic benefits. Through detailed analysis of its working principle, product parameters and application scenarios, it can be seen that the catalyst has broad market prospects and development potential. However, to achieve its large-scale promotion and application, some technical and economic challenges still need to be overcome, such as improving catalytic performance, enhancing anti-toxicity performance, and reducing production costs. Future research should focus on these issues, promote technological innovation and industrial upgrading of low-atomization odorless catalysts, and make greater contributions to the global environmental protection cause.

Examples of low atomization and odorless catalysts in artificial leather production

Background of application of low atomization and odorless catalysts in artificial leather production

As a material widely used in clothing, furniture, automotive interiors and other fields, artificial leather is crucial to its production process and quality control. With the continuous increase in consumer requirements for environmental protection and health, the odors and harmful substances produced by traditional catalysts in the production of artificial leather have gradually become bottlenecks in the development of the industry. Especially in the fields of automotive interiors, household goods, etc., the application of low atomization and odorless catalysts is particularly important.

Traditional catalysts such as organotin compounds, although excellent in promoting polymerization, are easily decomposed at high temperatures, producing volatile organic compounds (VOCs). These compounds are not only harmful to human health, but also cause product surfaces. Atomization occurs, affecting the appearance and performance of the product. In addition, the odor problem of traditional catalysts has also seriously affected the working environment of workers and the user experience of consumers.

In order to deal with these problems, in recent years, the research and development and application of low atomization and odorless catalysts have gradually become a hot topic in the artificial leather industry. Low atomization odorless catalysts have excellent catalytic properties and can significantly reduce or eliminate product atomization phenomena and odor problems without affecting production efficiency. This type of catalyst can not only meet strict environmental protection standards, but also improve the quality of products and market competitiveness.

This article will discuss in detail the application examples of low atomization and odorless catalysts in artificial leather production, analyze their technical characteristics, product parameters, and application scenarios, and conduct in-depth discussions in combination with domestic and foreign literature, aiming to provide relevant enterprises and researchers with Reference for value.

Technical features of low atomization odorless catalyst

The reason why low atomization and odorless catalysts can be widely used in artificial leather production is mainly due to their unique technical characteristics. Compared with traditional catalysts, low atomization and odorless catalysts show significant advantages in the following aspects:

1. Efficient catalytic performance

Low atomization odorless catalysts usually adopt advanced molecular design and synthesis processes, which can achieve efficient catalytic effects at lower doses. Studies have shown that the active centers of this type of catalyst have higher selectivity and stability and can maintain good catalytic performance over a wide temperature range. For example, some low atomization odorless catalysts can effectively promote the cross-linking reaction of polyurethane (PU) resins in a temperature range of 100°C to 200°C without significant side reactions or decomposition products.

Catalytic Type Active temperature range (°C) Best dosage (wt%)
Traditional Organotin Catalyst 150-250 0.5-2.0
Low atomization odorless catalyst 100-200 0.1-0.5

As can be seen from the table, low atomization odorless catalysts can not only function at lower temperatures, but also require significantly reduced amounts. This not only reduces production costs, but also reduces the impact of catalyst residue on product quality.

2. Low atomization characteristics

Atomization phenomenon refers to the catalyst or other additives evaporate at high temperatures and form a layer of mist on the surface of the product, affecting the transparency and gloss of the product. The low-atomization odorless catalyst reduces the volatility of the catalyst at high temperatures by optimizing the molecular structure, thereby effectively inhibiting the occurrence of atomization. Studies have shown that the volatile nature of low atomization and odorless catalysts is 30%-50% lower than that of traditional catalysts, especially in artificial leather applications such as automotive interiors, which is particularly important.

Catalytic Type Atomization rate (%) Surface gloss (60°)
Traditional Organotin Catalyst 15-20 80-85
Low atomization odorless catalyst 5-10 90-95

It can be seen from the table that low atomization odorless catalyst not only significantly reduces the atomization rate, but also improves the surface gloss of the product, making the product appearance more beautiful.

3. Odorless properties

Traditional catalysts often release pungent odors during production, which adversely affect workers’ health and working environment. The low atomization odorless catalyst effectively inhibits the generation of odor by introducing special functional groups or adopting a closed structure. Studies have shown that the odor intensity of low atomization odorless catalysts is 70%-80% lower than that of traditional catalysts, and produces almost no odor during the production process.

Catalytic Type Odor intensity (grade) Comfort in working environment
Traditional Organotin Catalyst 4-5 Poor
Low atomization odorless catalyst 1-2 Good

It can be seen from the table that the odorless properties of low atomization odorless catalysts not only improve workers’ working environment, but also improve production efficiency and reduce shutdowns and complaints caused by odor problems.

4. Environmental protection and safety

Another important feature of low atomization odorless catalyst is its environmental protection and safety. Traditional catalysts such as organotin compounds will release harmful heavy metal ions and volatile organic compounds (VOCs) during production and use, which will constitute a strong impact on the environment and human health.Strong. The low-atomization and odorless catalyst adopts more environmentally friendly raw materials and synthesis processes to avoid the formation of harmful substances. Research shows that the VOC emissions of low atomization and odorless catalysts are 60%-80% lower than those of traditional catalysts, and they comply with EU REACH regulations and Chinese GB/T 39551-2020 and other environmental protection standards.

Catalytic Type VOC emissions (g/m²) Whether it meets environmental protection standards
Traditional Organotin Catalyst 50-100 Not in compliance
Low atomization odorless catalyst 10-20 Compare

It can be seen from the table that the environmental performance of low atomization and odorless catalysts is far better than that of traditional catalysts and can meet increasingly stringent environmental protection requirements.
