Defoamers, also known as defoamers or defoamers, will produce many foams that affect production during industrial production, and defoamers need to be added. It is widely used to remove harmful foam produced in the production process of latex, textile sizing, food fermentation, biomedicine, paint, petrochemical, papermaking, industrial cleaning, sewage treatment and other industries.

The unique anti-foaming properties of defoamers make them widely used. It has low surface tension, high activity, strong defoaming ability; no change in heat resistance and high temperature, low volatility; good chemical stability, chemical inertness, does not react with other substances, and can be used under harsh conditions; no side effects.

The defoamers on the market are mainly divided into three categories: fermentation defoamers, silicone defoamers and sewage treatment defoamers.

Fermentation defoamer is used in the fermentation industry, it overcomes the stability of high temperature sterilization before fermentation, the inhibition of bacterial growth during fermentation and the shortcomings of fouling in fermentation tanks. Fermentation defoamer is suitable for biological, pharmaceutical and other fermentation processes, such as defoaming in the production and fermentation process of various antibiotics, cephalosporins, penicillin, yeast, soybean protein, amino acids, and spores. Defoaming in industries such as industrial sugar refining, food processing, and elimination of other aqueous foams.

Silicone defoamers are widely used. Due to the special chemical structure of silicone oil, it is neither compatible with water or substances containing polar groups, nor is it compatible with hydrocarbons or organic substances containing hydrocarbon groups. Due to the insolubility of silicone oil to various substances, it has a wide range of applications. It can be used not only in water system for defoaming, but also in oil system.

Sewage treatment defoamer is easy to disperse in water and can be well compatible with liquid products. Its superior rapid dispersibility can be evenly dispersed into water-based systems. Its unique performance is used in various sewage treatment processes such as circulating water treatment, papermaking sewage, printing and dyeing sewage, industrial sewage, chemical sewage, various types of wastewater treatment, urban sewage biological wastewater treatment system and chemical cleaning.
