Classification of defoamer

Types of Defoamers

Defoamers can be classified into five categories according to different classification standards, such as solid particle type, emulsion type, dispersion type, oil type and paste type;According to the application of defoamer in different industrial production, it can be divided into textile industry defoamer, paper industry defoamer, coating industry defoamer, food industry defoamer and petroleum industry defoamer;According to the chemical structure and composition of defoamer, it can be divided into mineral oils, alcohols, fatty acids and fatty acid esters, amides, phosphate esters, silicones, polyethers, and polyether-modified polysiloxanes etc.

Technical data

The defoamer should have the following properties:①Strong defoaming power and less dosage; ②Adding to the foaming system does not affect the basic properties of the system, that is, it does not react with the defoamed system;③ Small surface tension; ④ Good balance with the surface;⑤Good heat resistance; ⑥Good diffusivity and permeability, high positive spreading coefficient;⑦Chemical stability, strong oxidation resistance; ⑧Gas solubility, good permeability;⑨ Low solubility in foaming solution; ⑩ No physiological activity and high safety.
