In modern industrial production, whether in chemical industry, pharmacy, food processing, coating, papermaking, textile and other fields, the generation of foam is often a headache. Foam not only affects production efficiency and increases energy consumption, but also may have adverse effects on product quality, and even cause safety accidents. Therefore, defoamers play a crucial role as a key additive in industrial production.

Defoamers play a role in two ways: one is to destroy the surface tension of foam and make foam burst rapidly; The second is to destroy the stability of foam by infiltrating into the foam liquid membrane, so as to achieve defoaming effect. According to their different chemical compositions, defoamers can be divided into various types such as organic silicon defoamers, mineral oil defoamers, polyether defoamers, etc. Each type has its specific application scenarios and advantages.

The application field of defoamer is also increasingly wide. In the chemical industry, the control of foam is particularly important in the process of chemical reaction, especially those processes involving gas release, such as polymerization, fermentation, etc. Defoamer can effectively avoid foam overflow and ensure production safety. In terms of food processing, in the process of beer brewing, fruit juice concentration, dairy products processing, etc., foam not only affects the appearance of products, but also may accelerate oxidation deterioration. The use of food grade defoamer can effectively remove foam on the premise of ensuring safety. In terms of coatings and inks, foam will affect the uniformity and gloss of coatings in the production and application of coatings and inks. The addition of defoamers can ensure stable quality of coatings and inks. In addition, in the paper industry, in the process of pulp and paper making, foam will affect the uniformity of pulp and the molding quality of paper. The application of defoamers helps to improve paper quality and production efficiency.

With the continuous advancement of industrial technology, the performance of defoamers is also constantly optimized to meet more complex and changing process requirements. In the future, defoamers will play a key role in more fields, promoting the green and efficient development of industrial production.
