Silicone defoaming agent formula is made of silicone grease, emulsifier, fungicide, stabilizer with appropriate amount of water through the process of production.Physical morphology: oil, solution, emulsion, solid.According to the composition: silicone oil, composite, silicone polyether;

  1、The main ingredient of silicone grease is polysiloxane, silicon dioxide or other non-oil soluble polymers.

  2. The carrier in the formula plays the role of supporting medium to the silicone grease, which is convenient to infiltrate the defoaming material into the foaming system.The carrier can be hydrocarbon oil or water or fatty alcohol or solvent;

  3, the main components of the organic silicon defoamer silicone foam composition is not soluble, but is in the process of defoaming agent must quickly emulsifying and dispersing spreading the surface of the foaming system or in the foaming system, so the defoaming agent production must join emulsifier, help defoaming agent faster, more contact surface, thus improve the effect of foam material.Commonly used emulsifiers are non-ionic surfactants, such as TWEEN, OP or polysiliconic surfactants, etc.

  4. The fungicide in the formula is to prevent the product from being damaged by bacteria during storage.It could be something like cassone;

  5, the formula to maintain the stability of defoaming material in the carrier, the use of the product has a certain viscosity, such as water-based thickener can be: carboxymethyl cellulose;

The process of silicone defoaming agent is the reverse process of foam stabilization. From the perspective of mechanism, it includes two aspects: one is to inhibit the generation of foam, and the other is to eliminate the bubbles generated.Correspondingly, silicone defoaming agent is a substance that can change the interface state of the system, destroy or inhibit foam.As a good silicone defoaming agent must have these basic conditions: basically insoluble in foaming liquid, surface tension is lower than foaming liquid, can quickly disperse in foaming liquid.Defoaming agent DF-1O2C, 805 are this type of products.

  Silicone defoaming agent is monosodium glutamate in the industry, some people say it is the catalyst of science and technology, new silicone defoaming agent has higher surface activity, wide application of products, foam suppression lasting, defoaming ability is strong, less dosage, non-toxic, no side effects, good stability, long-term storage, convenient transportation, economic and practical.

  polysiloxane

  Polysiloxane is a kind of polymer with repeated Si-O bond as the main chain and directly connected to organic groups on silicon atoms, where R stands for organic groups, such as methyl, phenyl, etc.N is the number of organic groups connected on the silicon atom (between 1 and 3);M is the degree of polymerization (m not less than 2).

  Its commercial products include: silicone oil, silicone ring, silicone rubber, silicone resin and so on.Insulation effect is very good, in the aviation field has a very important position.
