In modern industrial production and daily life, the problem of bubbles is everywhere, from chemical industry, food, medicine to construction, environmental protection and many other fields, the generation of bubbles often bring a lot of problems to the production process and product quality. Polyether modified silicon defoamer, as a new defoamer with the advantages of both polyether and silicone defoamer, is gradually emerging and becoming an efficient new choice to solve the foam problem in many industries.



Polyether modified silicon defoamer has excellent properties due to its unique structure. It is made of polyether chain segment and polysiloxane chain segment by chemical bonding, and this special molecular structure gives it the good water solubility of polyether and the low surface tension of silicone. Polyether chain segment can enhance the dispersibility and stability of defoamer in aqueous solution, which makes it easier to interact with other components in the system. The polysiloxane segment can spread quickly on the surface of the foam by its very low surface tension, destroying the stability of the foam, so as to achieve rapid defoaming and lasting foam suppression effect.


Polyether modified silicon defoamer is widely used in chemical industry. In the production process of synthetic rubber, plastic and other polymer materials, polymerization reaction, emulsion polymerization and other processes are prone to produce a large number of foams, these foams will not only affect the normal progress of the reaction, but also may lead to a decline in product quality. Polyether modified silicon defoamer can quickly eliminate foam without affecting the reaction system, ensure the smooth progress of the reaction, and improve the quality and yield of the product. For example, in the emulsion polymerization process of styrene butadiene rubber, the generation of foam will cause the polymerization reaction to be uneven and affect the performance of rubber. After using polyether modified silicon defoamer, the generation of foam can be effectively controlled, the polymerization reaction is more stable, and the styrene butadiene rubber produced is of higher quality and better performance.


In the food industry, the safety of defoamer is of Paramount importance. Polyether modified silicon defoamer, as a safe and efficient food additive, plays an important role in food processing. In the production of fermented food, such as beer, yogurt, bread, etc., microbial fermentation will produce a large number of bubbles, which will affect the taste and quality of food if not eliminated in time. Polyether modified silicon defoamer can quickly eliminate foam without affecting microbial fermentation, and ensure the quality and taste of food. At the same time, it meets the strict standards of food additives and does not cause any harm to human health. For example, in the beer brewing process, the use of polyether modified silicon defoamer can effectively control the foam in the fermentation process, making the beer taste more refreshing and the foam more delicate and lasting.


The pharmaceutical industry has high requirements for product quality and safety. Polyether modified silicon defoamer has important applications in drug synthesis and preparation production. In the process of drug synthesis, the foam in the reaction system may affect the progress of the reaction and the purity of the product. Using polyether modified silicon defoamer can quickly eliminate the foam and ensure the smooth progress of drug synthesis. In the production of preparation, such as injection, oral liquid, etc., the presence of foam will affect the quality and stability of the product, and polyether modified silicon defoamer can effectively eliminate foam and improve the quality and safety of the preparation. For example, in the production process of antibiotics, polyether modified silicon defoamer can eliminate the foam produced in the fermentation process to ensure the yield and quality of antibiotics; In the preparation process of oral liquid, it can eliminate the foam generated during the filling process, making the product more beautiful and stable.


In the construction industry, polyether modified silicon defoamer is also widely used. In the production process of concrete, waterproof coating and other building materials, mixing, mixing and other operations are easy to produce a large number of foams, which will affect the performance of the material and the construction effect. Polyether modified silicon defoamer can quickly eliminate foam, improve the quality of building materials and construction efficiency. For example, in the production of concrete, the use of polyether modified silicon defoamer can reduce the content of bubbles in concrete and improve the strength and durability of concrete; In the production of waterproof coating, it can make the coating better leveling, more uniform coating, improve the waterproof effect.


In addition, polyether modified silicon defoamer also plays an important role in the field of environmental protection. In the process of sewage treatment, aeration, stirring and other operations will produce a lot of foam, which will not only affect the normal operation of sewage treatment equipment, but also may lead to sewage overflow and pollute the environment. Polyether modified silicon defoamer can effectively eliminate foam and ensure the smooth progress of sewage treatment. At the same time, it is environmentally friendly and will not cause pollution to water and soil. For example, in the municipal sewage treatment plant, the use of polyether modified silicon defoamer can effectively control the foam in the aeration tank, improve the efficiency of sewage treatment, and reduce environmental pollution.


Polyether modified silicon defoamer provides an efficient and safe defoamer solution for many industries with its unique properties and wide application fields. It not only improves production efficiency, reduces production costs, but also ensures product quality and safety, and has played a positive role in promoting the development of various industries. With the continuous progress of science and technology and the continuous development of industry, the performance of polyether modified silicon defoamer will continue to improve, and the application field will continue to expand, I believe that in the future, it will bring more surprises and value to more industries, and become a bright star in the field of defoamer.
