What is the difference between water-soluble defoamer and oil-based defoamer?

We all know that although defoamers are a relatively small industry in the chemical industry, there are many different types of defoamers and their functions. From a general perspective, defoamers are mainly divided into water-soluble defoamers and oil-based defoamers. Everyone knows what defoamers are, but they may not be very clear about water-based and oil-based defoamers. Some people even ask this question Are the two the same… Today, Kaiyin Chemical will introduce to you what is the difference between water-soluble defoamers and oil-based defoamers?

Water-soluble defoamer

Water-soluble defoamer is a modified silicone polydimethylsiloxane high-efficiency defoamer emulsion, which can be used to eliminate foam in aqueous systems. Because it is easy to disperse in water, it can be well mixed with liquid products, and it is not easy to demulsify and float oil. It is a general-purpose broad-spectrum room temperature defoamer. Suitable for use in water-soluble foaming systems, with good dispersibility, good wettability, fast defoaming, and strong antifoaming performance. It cannot be used in an oily system, and there will be oil floating and suspended matter.

Oil-based defoamer

Oil-based defoamer is a liquid oil-based powerful defoamer, specially designed for various oil-water systems, with outstanding rapid defoaming and long-lasting foam suppression , especially in oily systems with good dispersibility, ideal for foam control in acid-base systems with high temperatures above 200 degrees and about 20%. Suitable for use in oily foaming systems, with good dispersibility, fast defoaming and strong antifoaming performance. It cannot be used in water-soluble systems, and will appear in an incompatible state.

The difference between water-soluble defoamers and oil-based defoamers:

Water-based defoamer is a water-based system formed after emulsification with emulsifiers and other fillers. The raw materials used in the production process are non-toxic and harmless to the 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, medicine, and food fermentation industry.

The oil-based defoamer is not emulsified and consists of mineral oil and polyether. It has outstanding defoaming and antifoaming properties, especially good dispersion in oily systems, and is less affected by pH. Mainly used in various oil-water systems, such as synthetic resins, adhesives, adhesives, water reducers, phosphites, chemical synthesis, drilling mud, crude oil distillation, lubricating oil, etc…

Okay, after reading this sharing, do you know a lot about these two? In fact, there is a big difference between the two, but it cannot be said that water-based is better than oil-based, after all, both can be used in their respective fields.
