DOWDF 103

Defoamer Defoamer, also known as anti-foam agent, in the process of industrial production will have a number of harmful bubbles, you need to add defoamers. Widely used clear latex, textile sizing, food fermentation, bio-medicine, paint, petrochemicals, paper, industrial cleaning and other industries in the manufacturing process harmful foam. 1) The role of active ingredients: broken foam, foaming, reduce the surface tension: on behalf of property: silicone oil, polyether, high alcohol. (2) emulsifier role: to make the active ingredient dispersed into small particles, easy to disperse in the water, better play defoaming, foam inhibition effect. Representative objects: Wang (H) phenol polyoxyethylene ether, salt, soap, op series, Tween series, Sri plate series. (3) vector function: to help carriers and the combination of foaming system, easy to spread foam system, there is the combination of the low surface tension of their own, contribute to suppressing foam, and reduce costs. Representative objects: In addition to solvents other than water, such as aliphatic hydrocarbons, aromatic hydrocarbons, oxygenated solvents, etc. (4) the role of emulsifying additives: emulsify better. Representative objects: * Dispersant: hydrophobic silica, etc.; * Tackifier: CMC, polyethylene ether.
