What are the ingredients of defoaming agent?
In the process of industrial production, many harmful foams will be generated, and defoamers need to be added. Do you know what the ingredients of defoamers are? Let’s take a look.
Ingredients of defoamers:
(1) Active ingredients
Function: breaking bubbles, defoaming, reducing surface tension:
Representatives: silicone oil, polyethers, higher alcohols, mineral oil, vegetable oil, etc.
(2) Emulsifier
Function: dispersing the active ingredients into small particles, making it easier to disperse in water, and better playing the role of defoaming and defoaming.
Representatives: nonyl (octyl) phenol polyoxyethylene ether, soap salt, OP series, Tween series, Span series, etc.
(3) Carrier
Function: helps to combine the carrier and the foaming system, and is easy to disperse into the foaming system. Combining the two, its own surface tension is low, which helps to defoam and reduce costs.
Representative substances: solvents other than water, such as aliphatic hydrocarbons, aromatic hydrocarbons, oxygen-containing solvents, etc.
(4) Emulsifying agents
Function: to improve the emulsification effect.
Representative substances: *Dispersant: hydrophobic silica, etc.; *Thickener: CMC, polyethylene ether, etc.
The above is an introduction to the ingredients of defoamers. I hope it will be helpful to you. If you have any other related knowledge to learn, you can consult us and we will have professionals to answer your questions.
