Silicone Oil Emulsion Defoamer

Silicone oil emulsion type defoamer is generally an oil-in-water (O/W) emulsion, that is, water is the continuous phase, and silicone oil is the discontinuous phase. It is to pre-mix silicone oil, emulsifier and thickener, and then gradually add water to mix, and finally grind repeatedly in a colloid mill until the desired emulsion is obtained.

Main type

1. Silicone oil emulsion defoamer based on dimethyl silicone oil

This type of defoamer is prepared from dimethyl silicone oil plus emulsifier and water, and can be widely used in fermentation, food, paper, fiber, pharmaceutical, synthetic resin and so on.

2. Silicone oil emulsion defoamer based on methyl ethoxy silicone oil

This type of defoamer is made of methyl ethoxy silicone oil and compounding agents.

3. Silicone oil emulsion defoamer based on ethyl silicone oil

In recent years, silicone defoamers are developing in the direction of silicone-polyether block copolymerization (or graft copolymerization). Since this type of defoamer has the characteristics of both silicone and polyether, the defoaming power is greatly improved; the silicone-polyether copolymerized defoamer can also be called a self-emulsifying silicone Block (or graft) a hydrophilic ethylene oxide chain or ethylene oxide propylene oxide chain in the silicone molecular chain, so that the hydrophobic siloxane part is combined with the hydrophilic polyether, such a molecule has a larger As a defoamer, it has a large spreading coefficient, can be evenly dispersed in the foaming medium, and has high defoaming effect. It is a new type of high-efficiency defoamer. This kind of self-emulsifying silicone oil without the use of emulsifiers, the defoaming effect is quite satisfactory for some systems, and it is especially suitable for those occasions where the use of general silicone oil emulsions is not suitable and the general silicone oil emulsions are incompetent.

Packing

Packed in 25kg plastic drum or iron drum, can be customized if necessary.

Storage

It is suitable for storing substances at 10~30°C near the park or in the sun. Add acid, alkali, salt and other substances to this product and use it according to the general chemical storage method, and then ensure that it is sealed to avoid deterioration.
