Select defoamers to comply with the following: 2, the surface tension of the liquid is less than sparkling. Only defoamers intermolecular forces between small, less than sparkling liquid surface tension, defoamers particles before they can bubble membrane immersed and expansion. Notably, the surface tension of the bubble generation liquid surface tension of the solution is not, but the surface tension of the solution to help the bubble. 3, and the bubble generation liquid does not chemically react. Defoamer reaction with the bubble generation liquid, on the one hand the role of a defoaming agent lose aqueous coating defoamers, other hand, may produce harmful substances, affect the growth of microorganisms. How to choose defoamers? 5, volatile small professional industrial grade defoamers, long duration of action. First, make sure the system requires the use of defoamers, aqueous systems or oil system. Such as fermentation industry, it is necessary to use oil-based defoamers, such as polyether modified silicone or polyether. Water-based paint industry should aqueous defoamers, silicone defoamers. Select the defoamers, compare the amount added in the reference price, can be drawn from the most suitable defoamers most economical product.
