Everyone knows that although defoaming agents are a relatively small industry in the chemical industry, there are many different types of defoaming agents and their functions. From a general perspective, defoaming agents mainly include water-soluble defoaming agents and oil-based defoaming agents. Everyone knows what a defoaming agent is, but may not know much about water-based and oil-based defoaming agents. Some people even ask this Are the two the same… Today, Chemical Industry will introduce to you what is the difference between water-soluble defoamer and oil-based defoamer?
Water-soluble defoaming agent
Water-soluble defoamerYes A modified silicone polydimethylsiloxane high-efficiency defoamer emulsion that can be used to eliminate foam in aqueous systems. Because it is easily dispersed in water and can be well miscible with liquid products, it is not easy to break emulsions and float oil. It is a general-purpose broad-spectrum room-temperature defoamer. Suitable for use in water-soluble foaming systems, with good dispersion, good wettability, fast defoaming and strong foam suppression performance. It cannot be used in oily systems, as oil drift, suspended matter, etc. may occur.
Oil-based defoaming agent
Oil-based defoameris a liquid A powerful oil-based defoaming agent, specially designed for use in various oil-water systems. It has outstanding rapid defoaming and long-lasting foam suppression. It has good dispersion in oily systems and can control foaming in acid and alkali systems at temperatures above 200 degrees and about 20%. ideal. Suitable for use in oily foaming systems, with good dispersion, fast defoaming and strong foam suppression performance. It cannot be used in water-soluble systems, as it will cause incompatibility.
The difference between water-soluble defoamer and oil-based defoamer ：
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, pharmaceuticals, and food fermentation industries.
Oil-based defoaming agents are not emulsified and are composed of mineral oil and polyether. It has outstanding anti-foaming and anti-foaming properties, especially good dispersion in oily systems, and is less affected by pH. Mainly used in various oil and water systems, such as synthetic resins, adhesives, adhesives, water reducing agents, phosphites, chemical synthesis, drilling mud, crude oil distillation, lubricants, etc…
Okay, after reading this sharing, do you know much 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.
