11, water defoamers Silicone defoamers for aqueous foam system has a strong defoaming function, add a small amount and the cost is relatively low, is ideal defoamers aqueous systems 12, high temperature anti-foaming agent heat and acid resistance, high shear and a wide range of PH value (2-14), high temperature (300 ℃) are stable under the conditions, the system can be used for water and oil foaming, defoamers Low-cost, the higher the temperature, the higher the efficiency of use, Shandong defoamers, the better. Washing additives can be used in the next, oil drilling and other kinds of extreme conditions of high temperature and strong acid medium defoaming. Composition (1) the role of active ingredient: breaking foam, defoaming, reduce the surface tension: representation of: silicone, polyether, a higher alcohol, mineral oil, vegetable oil and the like. [2] (2) emulsifier: the active ingredient is dispersed into small particles, dispersed in water to facilitate better serve defoaming effect. Representative matter: Wang (octyl) phenol ethoxylates, soaps, op series, Twain series, Andean series. (3) vector roles: help-bound carrier and foaming system, easy to disperse in a foaming system, defoamers, to combine the two, defoamers manufacturers, low surface tension of its own to help antifoam, and the cost can be reduced. Representative were: solvent other than water, such as aliphatic hydrocarbons, aromatic hydrocarbons, oxygenated solvents. _ Three defoamers Low level chemical quality assurance (certification) _ defoamers provided by the Jinan Chemical Co., Ltd. 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.
