Organosilicon defoamer is made of silicone grease, emulsifier, waterproof agent, thickener, etc. with appropriate amount of water by mechanical emulsification. It is characterized by low surface tension, high surface activity, strong defoaming power, low consumption and low cost. It is immiscible with water and most organic matters, and can defoaming most bubble media. It has good thermal stability and can be used in a wide temperature range of 5 ℃ - 150 ℃; it has good chemical stability and is difficult to react with other substances. It can be used in acid, alkali and salt solutions as long as the configuration is appropriate, without damaging the product quality; it also has physiological inert ld250g / kg mice, which are usually used in food and medicine industries. It has the functions of inhibiting and breaking bubbles for all bubble systems and belongs to the category of broad-spectrum defoamer. It is widely used for defoaming in detergent, papermaking, pulp, sugar making, electroplating, chemical fertilizer, additives, wastewater treatment and other production processes. In the petroleum industry, it is widely used in the desulfurization of natural gas, accelerating the separation of oil and gas; it is also used in the drying of glycol, extraction of aromatic hydrocarbon, processing of asphalt, dewaxing of lubricating oil and other devices to control or inhibit bubbles. In textile industry, it is used for defoaming in dyeing, refining, sizing and other processes; in chemical industry, it is used for defoaming in synthetic resin, latex, paint, ink and other processes; in food industry, it is used for defoaming in various concentration, fermentation, distillation processes. The silicone grease can be applied on the wall, the outlet or on the metal net for defoaming. It can be used for defoaming in oil system. Silicone grease and low viscosity silicone oil can be used as water emulsion, which can be used for defoaming in various aqueous systems. In medicine, it is usually used to remove the flatulence of organs or stomach organs before operation, X-ray and gastroscopy.


Defoamers can be roughly divided into two categories: one can eliminate the generated bubbles, such as ethanol; the other can inhibit the formation of bubbles, such as emulsified silicone oil. The defoamers approved for use in China are emulsified silicone oil, high carbon alcohol fatty acid ester complex, polyoxyethylene polyoxypropylene pentaerythritol ether, polyoxyethylene polyoxypropanol amine ether, polyoxypropylene glycerin ether and polyoxypropylene

Combined with the advantages of polyether and organosilicon defoamer, it is non-toxic and harmless, harmless to bacteria, with a small amount of additives, and is a cost-effective product
