Retardant amine catalyst 8154: a right-hand assistant to reduce odors during production

In industrial production, various chemical reactions and process flows are often accompanied by headache-inducing “by-products” – odor. This odor not only affects the surrounding environment of the factory, but can also pose a threat to employee health. As an efficient and environmentally friendly catalyst, the delay amine catalyst 8154 has performed well in reducing odors in the production process and has become the new favorite of many chemical companies.

What is the delayed amine catalyst 8154?

The retardant amine catalyst 8154 is a catalyst specially used in the polyurethane foaming process. It ensures balance of each stage during the foam forming process by adjusting the reaction rate, thereby reducing unnecessary side reactions. This not only improves the quality of the product, but also effectively reduces the odor generated during the production process.

Main Functions

Promote the reaction of isocyanate with water: Helps to produce carbon dioxide gas and promotes foam expansion.
Control gelation time: Optimize the foam structure to prevent premature or late solidification.
Reduce by-product formation: Reduce the production of volatile organic compounds (VOCs) such as aldehydes, which are often the main source of odors.

The working principle of delayed amine catalyst 8154

The reason why the delayed amine catalyst 8154 can effectively reduce odor in the production process is mainly due to its unique molecular structure and mechanism of action. First, it can accurately control the reaction rate between isocyanate and polyol, avoid local high temperatures caused by excessive reaction, thereby reducing the generation of thermal decomposition products. Secondly, by adjusting the system pH value, the formation of certain volatile by-products, such as formaldehyde and formic acid, is inhibited.

Effective strategies to reduce odor

Although the delayed amine catalyst 8154 itself has a significant odor reduction effect, in actual applications, other measures are needed to improve this advantage.

Process Optimization

Strictly control raw material ratio

Each raw material has its best use ratio. Too much or too little will break the original chemical balance and lead to unnecessary side reactions. For example, when the isocyanate is excessive, more ureaforate is easily formed, which is a compound with a strongly irritating odor.

Improving hybrid technology

Using advanced mixing equipment and technology can ensure that the catalyst is in full and uniform contact with other components. This not only improves the reaction efficiency, but also reduces abnormal reactions caused by excessive local concentrations.

Environmental Management

Strengthen the ventilation system

Good ventilation is one of the most effective ways to remove residual odor in the workshop. Design a reasonable airflow direction and speed to ensure that harmful gases can be quickly discharged from the outdoors while introducing fresh air to replenish them.

Installing an air purification device

For those odors that are difficult to completely eliminate with natural ventilation, consider installing a professional air purifier. They use activated carbon adsorption and ultraviolet sterilization to further purify pollutants in the air.

Equipment Maintenance

Check the status of the production equipment regularly and replace aging parts in time to prevent additional chemical reactions caused by mechanical failures. In addition, it is also important to keep the equipment surface clean, as accumulated dirt can become a new source of pollution.

Status of domestic and foreign research

Scholars at home and abroad have conducted a lot of in-depth research on the delayed amine catalyst 8154 and its application in reducing odor in production.

Domestic Research

In recent years, with the increase in environmental awareness, domestic scientific research institutions have invested more attention to green chemical technology. A study from the Department of Chemical Engineering of Tsinghua University showed that the use of delayed amine catalyst 8154 under specific conditions can reduce VOCs emissions by nearly 40%. In addition, the team has developed a real-time monitoring system based on IoT technology to evaluate the effectiveness of catalysts under different formulations.

Foreign progress

In foreign countries, especially developed countries in Europe and the United States, research in related fields has started early and achieved fruitful results due to strict environmental protection regulations. The new delay amine catalyst series launched by BASF, Germany, has added anti-oxidation and photolysis functions on the original basis, further improving the stability and scope of application of the product. Dupont, USAThe company focuses on exploring how to apply such catalysts to a wider range of industrial fields, including the manufacturing of automotive interior materials and the production of building insulation panels.

Conclusion

To sum up, the delayed amine catalyst 8154 has shown great potential in reducing odor during production due to its excellent performance. However, in order to truly achieve the goal of odor-free production, comprehensive measures need to be implemented from multiple angles. I hope that with the continuous advancement of science and technology in the future, we can find more perfect solutions and make our world a better place!
