シリコーン消泡剤の特性

The silicone oil-based defoamer is insoluble in water and mineral oil, so its antifoaming ability is strong as well as its antifoaming effect is greatly enhanced. Because Si-O bond and Si-C bond are relatively stable, and they are allowed to be used in systems containing a small amount of acid, alkali and salt. Most of the commonly used silicone defoamers in industrial production are a kind of secondary processing product of silicone oil made by adding dispersants to silicone oil, which are all liquid mixtures.

The antifoaming active ingredient of silicone defoamer is silicon paste. Hydrophobic silica particles in silicone paste can form a defoaming agent dispersion with silicone oil, help silicone oil droplets insert into the surface of foam film, reduce insertion resistance of silicone oil drops and foam drainage time, increase the depth of foam dispersant inserted on the surface of foam film, improve the ability to destroy the oil-water-air film, and accelerate the defoaming speed.

加熱条件下において、メチルMQシリコーン樹脂中のSI-OH結合は、ジメチルシリコーンオイル及び疎水性気相法シリカ中の残留Si-Ohと反応し、複雑な高分子鎖構造を持つ有機ポリマーを形成することができます。このポリマーはシリカの分散性を効果的に向上させ、シリカとジメチルシリコーンオイルの相乗的な消泡・防泡性能をさらに強化します。.

Emulsion type silicone defoamer uses two methyl silicone oil as the main raw materials, which is a defoamer emulsified by adding methyl MQ silicone resin and hydrophobic carbon black. It can be widely used in food, paper, leather, environmental management, and other aspects of chemical production.

Silicone defoamer is suitable for industrial circulating water, water treatment, circuit board cleaning, metal cutting fluid, metal cleaning, oil processing grinding fluid, and alkaline cleaning fluid. Also, it is suitable for defoaming of textile, printing and dyeing, emulsion polymerization, civil washing, various kinds of colorants and coatings.
