Too much foam is hindering production? Quickly understand the magic of silicone defoamers!
Are you often plagued by foam issues on the production floor? It not only slows down production but also affects product quality. Today, let's talk about the "all-rounder" in the industrial defoaming world—silicone defoamer. Why are silicone defoamers so powerful? Are they suitable for your production line? Let's find out!
How do silicone defoamers eliminate foam?
The core formula of silicone defoamer is very simple: polydimethylsiloxane (silicone oil) + silica + emulsifier. However, the defoaming ability of silicone defoamer is highly recognized in the industry.
1. Rapid Penetration: Silicone oil has extremely low surface tension, much lower than that of foam liquid films. Upon contact, the silicone oil can instantly penetrate into the foam and spread rapidly.
2. Powerful Foam Destruction: As the defoamer spreads on the surface of the liquid film, it carries away the liquid, disrupting the elastic balance of the foam surface and forcibly thinning the originally stable liquid film until it breaks instantly.
3. Long-Lasting Foam Suppression: Silicone oil particles are evenly dispersed in the system, acting like "sentinels" to prevent surfactant foaming in advance and prevent the formation of new foam.
Why are silicone defoamers so popular?
1. Extremely economical dosage, lower cost: The dosage of silicone defoamer is only 0.01% - 0.1%, far lower than that of polyether defoamers. You can solve more foaming problems with less money.
2. Chemically inert: Silicone antifoam itself does not participate in chemical reactions and does not change the pH, viscosity, or color of the system. It does not affect resin film formation, cutting fluid rust prevention, or pigment coloring.
3. Acid and alkali resistant, salt and calcium resistant: Silicone defoamer remains stable in environments with a pH range of 2-12. It maintains excellent defoaming effects in strong acids, strong alkalis, and high-salt slurries.
4. Versatile: Silicone defoamer is suitable for multiple industries, including papermaking, wastewater treatment, oil extraction, adhesives, steel rolling mill cleaning, etc.
