Silicone defoamer comprising polydimethylsiloxane generally like. Silicone defoamer defoamers poor solubility properties at room temperature, anti-foaming fast, suds defoamers better spot, but stratification occurs at high temperature, anti-foaming slower, suds poor and so on. Polyether defoamers include polyoxyethylene polyoxypropylene glyceryl ether and the like. Polyether defoamer defoaming a long time, good effect, anti-foaming speed, good thermal stability. For example, in fruit and vegetable drinks, soy, sugar and other production processes will be used defoamers. Defoamers can be divided into two categories: one to eliminate the bubbles have been produced, such as ethanol; the other is able to inhibit the formation of bubbles, such as silicone oil emulsion. Chinese license are emulsified antifoam silicone oil, higher alcohol fatty acid ester compound, a polyoxyethylene polyoxypropylene pentaerythritol ether, polyoxyethylene polyoxypropylene propanolamine ether, polyoxypropylene glyceryl ether and polyoxypropylene 6, The new self-emulsifying defoamer containing a special modified silicone. Has excellent heat resistance and acid resistance and chemical stability, over a wide temperature range are widely used foam to the harsh system of elimination and suppression. Defoamers spot, three level chemical quality assurance (certification), defoamers by Chemical Co., Ltd. Jinan three levels. Jinan three ping Chemical Co., Ltd. (www.sanpinghuagong.com) Shandong Jinan, chemical products leader, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. Three-ping Chemical leadership with the staff warmly welcome all inquiries negotiations to create three levels of chemical better future.
