China chemical polyether type antifoamer polyether type defoamer

Short Description:

Defoamer/antifoamer

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.

Product Detail

Product Tags

Substances that can reduce the surface tension of water, solutions, suspensions, etc., prevent the formation of foam, or reduce or eliminate the original foam.

Defoamer is widely used in food industry, paper industry, water treatment, oil extraction industry, printing and dyeing industry, coating industry, detergent industry, rubber latex industry, aerosol industry, daily chemical industry, pharmaceutical industry, dairy industry, etc. .

Composition

Active ingredients, emulsifiers, carriers and emulsification aids

Defoamer is an additive that eliminates foam.In the process of production and application in coatings, textiles, medicine, fermentation, paper making, water treatment and petrochemical industries, a large amount of foam will be produced.And then affect the product quality, production process. Based on the inhibition and elimination of foam, a specific amount of defoamer is usually added to it during production.

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.
