1 前言本消泡剂是采用二甲基硅油与非离子表面活性剂复配而成的乳状液消泡剂。外观呈浅灰色悬浮液体,pH值近中性。由于二甲基硅油的表面张力低于水溶液和油,因而此类消泡剂可用于石油、造纸、涂料等工业领域。本产品以二甲基硅油、表面活性剂、悬浮剂、增稠剂为原料制成消泡剂。 2 研制依据 2.1 由于工业领域各行各业的生产,泡沫的存在都会影响生产和产品质量,为了消除不利于生产的泡沫,需要加入一定量的消泡剂。 2.2 消泡剂在我国的应用和发展已有数十年的历史了,品种和数量随着科学的发展和工业领域的扩展而不断的增加。聚硅氧烷由于它独特的表面活性,用于消泡剂在我国已有数十年(30年代开始)的
1 Foreword The defoamer is a mixture of dimethyl silicone oil and nonionic surfactant emulsion defoamers. The appearance of light gray suspension liquid, pH near neutral. Due to the lower surface tension of simethicone than aqueous solutions and oils, such defoamers can be used in the petroleum, papermaking, coatings and other industrial fields. This product is made of dimethyl silicone oil, surfactant, suspending agent and thickener as defoamer. 2 basis for the development of 2.1 due to the production of various industries in the industry, the presence of foam will affect the production and product quality, in order to eliminate unfavorable foam, you need to add a certain amount of defoamer. 2.2 Defoamer application and development in our country has decades of history, variety and quantity with the scientific development and industrial expansion continues to increase. Due to its unique surface activity, polysiloxanes have been used in defoamers in our country for decades (beginning in 1930s)
