Defoamers are of great origin


With the development of domestic economy, the development of Defoamer Market is facing tremendous opportunities and challenges. In terms of market competition, there are more and more defoamer enterprises, and the market is facing the asymmetry of supply and demand. The defoamer industry has strong requirements for further shuffling. However, there is still much room for development in some Defoamer Market segments. Informationization technology will become the core competitiveness.


The production of defoamer is not a simple mixing and stirring of each component in defoamer. The specific technology and proportion of defoamer will vary greatly according to the level of research and development of each manufacturer, thus the quality of defoamer can be divided into good and bad.


Although the era of heroism by descent has passed, it is necessary to understand the descent of defoamers.


Blood composition of defoamers: active ingredients, emulsifiers, carriers, emulsifiers.


Functions of active ingredients: defoaming, defoaming, reducing surface tension; representatives are silicone oil, polyether, higher alcohols, etc.


The role of emulsifier: disperse active ingredients into small particles, easy to disperse in water, better play a defoaming, anti-foaming effect. Representatives: Nonyl (octyl) phenol polyoxyethylene ether, soap salt, etc.


Function of carrier: It is helpful for the combination of carrier and foaming system. It is easy to disperse into foaming system. Combining the two, the surface tension of carrier itself is low, which helps to restrain foaming and reduce cost. Representatives: Solvents other than water, such as aliphatic hydrocarbons, oxygen-containing solvents, etc.


The role of emulsifying aids: make the emulsifying effect better, representative: hydrophobic silicon dioxide, polyethylene ether and so on.


The slight adjustment of the proportion of each component in the blood of defoamers will bring subtle changes in defoamers'antifoaming properties.
