In the production of products or use, foam is often affecting the quality of products and use efficiency of the "block", at present in all industrial products or food industry, will encounter the problem of foam. But do not worry too much, the appearance of defoamer is used to eliminate foam. Today, let's share four types of commonly used water-based system defoamer.













What are the types of water-based system defoamer










1, silicone (resin) class: silicone is currently used more widely, because of its fast defoaming, less consumption, price concessions, often used in water treatment, sand washing, coal washing plant, shield mud, cleaning, petrochemical and other industries. Silicon-based water-based system defoamer has good defoaming and defoaming properties, so it is widely loved by everyone.


2, surfactants: This type of defoamer is actually an emulsifier, that is, the use of the dispersion of surfactants, so that the substance forming the foam in the water to maintain a stable emulsion state of dispersion, so as to avoid the formation of foam.


3. Paraffin: paraffin defoamer is a defoamer made of paraffin wax or its derivatives emulsified and dispersed by emulsifying agent, and its use is similar to that of surfactant emulsified defoamer.


4, tributyl phosphate: tributyl phosphate defoamer as nitrocellulose, cellulose acetate, chlorinated rubber and polyvinyl chloride plasticizer, rare metal extractant, etc., and developed, soluble in a variety of organic solvents, insoluble in water, applicable to a wide range of industries, due to its low surface tension, insoluble in water physical properties, can be used as an industrial defoamer, Effectively make the formed foam film in an unstable state and quickly defoaming.










In addition to the above four types of water-based system defoamer, there are polyether GPE, alcohols, and other non-silicon (silicon-free) defoamer. Different ingredients are used in different industries, water-based system defoamer can meet the needs of a number of industries, if you need to know more about foam solutions, please feel free to lift, leave you need to solve the foam problem.
