What are the ingredients of defoaming agent?
Defoamers, also known as antifoaming agents, will produce a lot of harmful foams during industrial production, and defoamers need to be added. So do you know what the ingredients of defoamers are? The following is an introduction:
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) Emulsifiers
Function: Disperse the active ingredients into small particles, which are easy to disperse in water and have better defoaming and antifoaming effects.
Representatives: nonyl (octyl) phenol polyoxyethylene ether, soap salt, OP series, Tween series, Span series, etc.
(3) Carriers
Function: It 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 suppress foam and can reduce costs.
Representative substances: solvents other than water, such as aliphatic hydrocarbons, aromatic hydrocarbons, oxygen-containing solvents, etc.
(4) Emulsifying aids
Function: to improve the emulsification effect.
Representative substances: dispersants: hydrophobic silica, etc.; thickeners: CMC, polyethylene ether, etc.
