5 Characteristics silicone antifoam defoamer comparison with other types of

Silicone defoamers are silicone oil added dispersing aids prepared for a class of silicone secondary processing products. Han Feng Chemical Co., oil type, silicone paste type, solution, emulsion, self-emulsifying type and powder type and other forms (detailed in the table below for everyone culvert peak production table). Water system and the non-foaming liquid water system, has a very good anti-foaming effect. Widely used in chemical, fiber, paper machine drainage sewage treatment and other industries; in which the fiber culvert peak silicone defoamers chemical treatment effect is obvious. Generally silicone oil defoamers in comparison with other types of defoamers, there are five characteristics:
1. On the chemical structure, different bath other organic compounds defoamers, non-polar, not with water and a polar group association occurs, it will not work with hydrocarbons different SP values occurs association . So silicone defoamers in water, animal and vegetable oils, high boiling mineral oil is not dissolved and the majority have a defoaming effect foaming system, and persistent suds is also very good.
2. surface tension, so have a very strong anti-foaming effect, the general amount of foaming liquid volume only 10X10 ^ 5 ~ 200X10 ^ -8, to tender to achieve good results. Due to the small amount of the performance of the final product is not affected.
3. chemical stability, heat resistance, anti-foaming neutral foaming system can adapt to the high temperature of 150 ?.
4. simethicone with physical inertia, can be used in the food industry, the cosmetics and pharmaceutical industry, which formulated defoamers human security. Silicone defoamers biochemical oxygen demand (BOD) is minimal. Defoaming systems for sewage sludge does not increase the load.
