As the name suggests, non-silicone defoamer is a silicone-free defoamer, mainly a complex of alcohols and fatty acids, mainly catalyzed by potassium hydroxide, and prepared by polymerization of propylene glycol or glycerol with propylene oxide and ethylene oxide. Non-silicone defoamerThe advantages include large diffusion coefficient, strong foam breaking ability, good stability and can avoid the phenomenon of silica spots, which is suitable for most non-silicon defoaming industries for defoaming and foam suppression.
Application scenario diagram of non-silicone defoamer).
1. What are the product characteristics of non-silicone defoamers?
1. Good diffusion.
Good diffusion, permeability, heat resistance, chemical stability, and strong oxidation resistance.
2. Acid and alkali resistance.
It has a wide range of use conditions, and has good effects in a variety of foam systems or acidic and alkaline conditions.
3. The dosage is small.
At a lower concentration, it can have a better defoaming and antifoaming effect, and the dosage is low and the cost is saved.
4. Strong defoaming.
It has strong defoaming and foaming inhibition ability, and does not affect the basic properties of the foaming system.
2. In which industries can non-silicone defoamers be used?
Non-silicone defoamer can be used in: water treatment, metalworking fluids, cutting fluids, metal cleaning, papermaking, building materials, water-based adhesives, textile printing and dyeing, circuit board cleaning, printing inks, industrial cleaning, oilfield industry, water-based coatings, desulfurization industry, washing, agriculture, fermentation, mining and beneficiation, rubber, water-based general, oily and water-based system general and other industries.
In summary,Non-silicone defoamerIt has good defoaming and foaming inhibition performance, and can be applied to defoaming in different foam systems, but it needs to be noted that not all foams can use non-silicone defoamers, we need to choose more suitable defoamer products for foam defoaming according to the foaming situation of the industry, comprehensive foaming reasons, so as to eliminate the impact of foam and maintain the normal operation of the production process.
