Silicone defoamers are silicone adddispersing aids prepared for a class of silicone secondary processing products.Oil type, silicone type ointment, solution, emulsion, self-emulsifying type andthe like powdered form. On the tax system and the non-foaming liquid watersystem, there is a very good anti-foaming effect. Widely used in petroleum,chemical, fiber, paper, food, fermentation, drainage and sewage treatment andother industries. Silicone defoamers comparison with other types of defoamers,there are five characteristics:
In the chemical structure, unlike otherorganic compounds defoamers, non-polar. Will work with water and polar groupsunderwent association nor hydrocarbon compounds different SP values occursassociation. Therefore, silicone defoamers are not dissolve in water, animaland vegetable oils, mineral oil, high boiling point, for most of the foamingsystem has a defoaming effect. Also, persistent suds is also very good.
Surface tension is small, it is also a verystrong anti-foaming effect. Usually only the amount of foaming liquid amount of10 × 10-6 ~ 200 × 10-6, will be able to achieve goodresults. Due to the small amount of the performance of the final product is notaffected.
Chemical stability, heat resistance,anti-foaming neutral foaming system can adapt to high temperature of 150 ℃.
Methyl silicone oil with physical inertia,can be used in the food industry, cosmetics and pharmaceutical industries,formulated defoamers human security.
Small BOD silicone defoamers andanti-foaming system for sewage sludge does not increase the load.
Variety models and more choice for avariety of foaming system.
