Bubbles are a common problem across various industries. Their formation can impact production and even product quality. How to efficiently and conveniently eliminate or control foam is a concern for every manufacturer. Therefore, defoamers have become the best solution for every manufacturer to address foam issues.
As the name suggests, a defoamer is a chemical additive that eliminates foam. When an organosilicone defoamer is added to a foaming system, it disperses quickly. The surfactant molecules align on the bubble surface. When the organosilicone defoamer reaches a certain concentration, and there are enough surfactant molecules, a thin film forms on the bubble wall, reducing its surface tension and increasing the gas-liquid contact area. This ultimately makes the bubbles less likely to coalesce and break. Compared to other types of defoamers, organosilicone defoamers have the following characteristics: 1. Wide application range: Due to the insolubility of silicone oil in various substances, it has a wide range of applications, suitable for both water and oil systems. 2. Low surface tension and good defoaming efficiency. 3. Good thermal stability, usable over a wide temperature range.
4. Good chemical stability; with proper formulation, silicone defoamers can be used in systems containing acids, alkalis, and salts. Silicone defoamers possess excellent defoaming and foam-suppressing properties, are characterized by low dosage, good chemical inertness, and the ability to function effectively under harsh conditions. In recent years, they have experienced rapid development, with new varieties and models constantly emerging to suit different application environments, and their application scope continuously expanding.
