What is the difference between the water-soluble defoamer and oil-based defoamer?
We all know that although defoamer is a relatively small industry in the chemical industry, defoamer has many different types and their role. From the general direction, antifoam defoamer mainly water-soluble defoamer and oil-based defoamer points, we all know what antifoam defoamer, may be water-based and oil-based defoamer is not very clear, and there are even people who ask whether the two are the same... Today RISE Chmical will give you an introduction to the difference between water-based defoamer and oil-based defoamer?
Water-soluble defoamer
Water-soluble defoamer is a kind of modified silicone polydimethylsiloxane high efficient defoamer emulsion, which can be used to eliminate the foam of water-containing system. Because water-soluble defoamer is very easy to disperse in water, can be well soluble with liquid products, not easy to break the emulsion bleaching oil, so water-soluble defoamer is a general-purpose broad-spectrum room-temperature type defoamer. It is suitable for use in water-soluble foaming system, with good dispersion, good wettability, fast defoaming and strong foam inhibition performance. Water-soluble defoamer can not be used in the oily system, there will be drifting oil, the state of the suspension and so on.
Oil-based defoamer
Oil-based defoamer is a kind of liquid oily strong defoamer, specially designed for all kinds of oil and water systems. Oil-based defoamer has outstanding fast defoaming, long lasting foam inhibition, especially in the oily system with good dispersibility, in the high temperature of more than 200 degrees, about 20% of the acid and alkali system foam control ideal. Oil-based defoamer antifoam is suitable for use in oily foaming system, good dispersion, fast defoaming, strong foam inhibition performance. Oil-based defoamer can not be used in water-soluble system, there will be immiscible state
Difference between water-based defoamer and oil-based defoamer
Water-based defoamer is a water-based system formed after emulsification of emulsifier and other fillers. The raw materials used in the production process are non-toxic and harmless to human body. It is especially suitable for defoaming in polyvinyl chloride resin, textile printing and dyeing, chemical reaction, petrochemical industry, metal processing industry, biological fermentation, water treatment, pharmaceuticals, food fermentation industry.
And the oil-based defoamer is not emulsified, composed of mineral oil and polyether. It has outstanding antifoaming and anti-foaming performance, especially in the oily system with good dispersibility and less affected by PH. Mainly used in a variety of oil and water systems, such as synthetic resins, adhesives, adhesives, water reducers, phosphite, chemical synthesis, drilling mud, crude oil distillation, lubricants, etc...
Well, we read this share whether the two know a lot about it? In fact, the two are very different, but can not say that the water-based better than the oil-based, after all, both can be used in the field that belongs to them.
