Industrial defoamer is a chemical additive widely used in various industrial fields, mainly used to eliminate foam in liquid. In many production processes, the existence of foam may lead to product quality degradation, equipment failure, production efficiency reduction and other problems. Therefore, the use of defoamers is of great significance for improving product quality and reducing energy consumption.

There are many types of defoamers, which can be roughly divided into organic compounds, silica, organosilicon, etc. according to their chemical composition. Specifically, there are alkali resistant defoamer, acid resistant defoamer, high viscosity foam defoamer, paint defoamer, paper defoamer, cement mortar defoamer, silicone defoamer for oilfield industry, cationic defoamer, fermentation defoamer and water treatment defoamer. These defoamers have their own characteristics and are suitable for different industrial production environments.

For example, alkali resistant defoamers can be used in high-temperature and strong alkali environments, with fast defoaming speed, long foam suppression time, good stability, low dosage, no floating oil, and are commonly used in papermaking black liquor treatment and textile printing and dyeing industries. In paper industry, defoamers can be used to eliminate foam in pulp and improve paper quality. In the textile industry, defoamers can be used to eliminate the foam produced by dyes and auxiliaries and improve the printing and dyeing effect. In the coating industry, defoamers can be used to eliminate foam in coatings and improve the stability and coating effect of coatings. In addition, defoamers also play an irreplaceable role in fields such as petrochemicals, wastewater treatment, oilfield industry, pharmaceuticals, and food processing.
