Silicone defoamers are silicone add dispersing aids prepared for aclass of silicone secondary processing products. Oil type, silicone typeointment, solution, emulsion, self-emulsifying type and the like powdered form.On the tax system and the non-foaming liquid water system, there is a very goodanti-foaming effect. Widely used in petroleum, chemical, fiber, paper, food,fermentation, drainage and sewage treatment and other industries. Siliconedefoamers comparison with other types of defoamers, there are fivecharacteristics:
In the chemical structure, unlike other organic compounds defoamers,non-polar. Will work with water and polar groups underwent association norhydrocarbon compounds different SP values occurs association. Therefore,silicone defoamers are not dissolve in water, animal and vegetable oils,mineral oil, high boiling point, for most of the foaming system has a defoamingeffect. Also, persistent suds is also very good.
Surface tension is small, it is also a very strong anti-foaming effect.Usually only the amount of foaming liquid amount of 10 × 10-6 ~ 200× 10-6, will be able to achieve good results. Due to the smallamount of the performance of the final product is not affected.
Chemical stability, heat resistance, anti-foaming neutral foamingsystem can adapt to high temperature of 150 ℃.
Methyl silicone oil with physical inertia, can be used in the foodindustry, cosmetics and pharmaceutical industries, formulated defoamers humansecurity.
Small BOD silicone defoamers and anti-foaming system for sewage sludgedoes not increase the load.
Variety models and more choice for a variety of foaming system.
