Silicone defoamer is a white viscous emulsion. It has been applied earlier and has a wide range. It has attracted more and more attention from all walks of life. Silicone defoamers are widely used in sewage, chemical, paper, power plants, paint, food, textile, pharmaceutical and other industries.


The main component of silicone defoamer is silicone oil. Silicone oil is a non-volatile oily liquid at room temperature. It is insoluble in water, animal and vegetable oils and mineral oils, or has a low solubility. It can withstand high temperatures and low temperatures. Therefore, after the silicone oil is added with water and emulsified with an emulsifier, the oily components with defoaming effect can be uniformly dispersed in the water.


Therefore, the amount of water added and the level of emulsification determine the effect and price of the silicone defoamer. The more water is added, the lower the solid content, and the price will naturally decrease. The defoaming effect is not as good as the high content of silicone defoamers. The solid content is an important indicator of silicone defoamers. The level of emulsification determines the stability and defoaming effect of the silicone defoamer. The stability is high. Water and silicone oil are not easy to layer, and they will not be separated after long-term storage. Therefore, stability is also an important indicator of silicone defoamers.
