Application of silicone defoamer in technology

Silicone defoamer is a common defoamer. It mainly eliminates foam generated in liquid. By changing the surface tension and interfacial tension of the liquid, the foam film is destroyed to achieve rapid defoamer and foam suppression. It is often widely used in water treatment, pharmaceuticals, food processing, textile printing and dyeing, papermaking, coatings, chemicals and other industries. Since the existence of foam will cause greater harm to product quality and production and construction processes, in order to maintain the normal operation of industry production and construction processes, it is necessary to select appropriate defoamer to eliminate these negative effects, among which organic Silicone defoamer has played a great role in promoting the development of the industry.
The application industries of silicone defoamer are very wide. In many industrial sectors such as water treatment, chemical industry, papermaking, coating, food, textile and so on, silicone defoamer has become an indispensable additive in the production process. . Its main function is to remove foam on the liquid surface of the process medium, thereby improving the separation, gasification and drainage effects of filtration, washing, extraction, distillation, evaporation, dehydration, drying and other processes, and ensuring that all types of materials are held and processed in containers capacity is fully utilized.

For example, in the papermaking industry, silicone defoamer are widely used in pulping, coatings, and papermaking. and papermaking wastewater treatment. Due to its low surface tension, high stability and high temperature resistance, silicone defoamer agents have excellent effects in controlling and eliminating foam problems in liquids.

Silicone defoamer are mainly made by polymerizing propylene glycol or glycerin with propylene oxide, ethylene oxide, etc. under the catalysis of potassium hydroxide. It is characterized by fast defoamer, strong stability, and no stains. It is suitable for defoamer and foam suppression needs in most silicone defoamer agent industries.
