The Difference Between Silicone Defoamer And Non-silicone Defoamer

Mar 28, 2019

    Defoamer, as its name implies, is an additive for eliminating foam. It is often used to eliminate harmful foams during industrial production. There are many kinds of defoamers, which are mainly divided into silicone defoamers and non-silicone defoamers. What is the difference in diameter? Let's take a look.

    1. Silicone defoamer:

    The silicone antifoaming agent is formed by mechanical emulsification of a suitable amount of water, such as a silicone grease, an emulsifier, a water repellent, and a thickening agent. It is characterized by small surface tension, high surface activity, strong defoaming power, low dosage and low cost. It is not miscible with water and most organic matter and defoams most bubble media. It has good thermal stability and can be used in a wide temperature range of -5 ° C ~ -150 ° C; its chemical stability is good, it is difficult to react with other substances, as long as the configuration is appropriate, it can be in acid, alkali, salt solution Used in, non-destructive product quality; it is also physiologically inert and is commonly used in the food and pharmaceutical industries. It has both anti-foaming and foam-breaking properties for all bubble systems and belongs to the broad-spectrum defoamer category. It is widely used in defoaming in the production processes of detergents, paper, pulp, sugar, electroplating, fertilizers, auxiliaries, and wastewater treatment.

    Second, the introduction of non-silicone defoamer:

    The non-silicone antifoaming agent is a liquid component which is slightly yellowish white and has a pH of about 7. The defoaming effect is extremely obvious. Non-silicone defoamers are processed from polyethers, alcohols, hydrocarbons, and the like. The non-silicon type defoamer has the advantage of being able to penetrate the inside of the foam quickly and diffuse rapidly. It can eliminate a variety of intractable foams and stabilize defoaming at high temperatures. And no silicon spots remain. good results.

    Features of non-silicone defoamer:

    The non-silicone defoamer is produced by imported technology and its composition is completely free of silicone. So there is no residue of silicon spots. Adding to water-based inks, inks, coatings, and glue does not cause problems in the product. Especially for the production of PCB circuit boards, the sewage treatment industry, etc. have a great help.

    Third, the use of non-silicone defoamer:

1. Modulate according to different foam systems. It is recommended to range from 0.4 to 0.5 percent.

2. Stir in water or working solution or add directly.

3. Use only in water systems below 100 degrees Celsius.

4. Stir well when using.
