Introduction to Widely Applicable Silicone Defoamers
Nov 22, 2024
Principle of Silicone Defoamer
Silicone defoamer achieves defoaming function by reducing liquid surface tension and destroying foam stability. Its main functions include:
Rapid defoaming: can quickly penetrate into the foam surface, destroy the elasticity and stability of the foam film, and make the foam disappear quickly.
Long-lasting antifoaming: forms a hydrophobic film on the liquid surface to inhibit the regeneration of foam.
High temperature and chemical corrosion resistance: suitable for defoaming needs under extreme conditions.
Silicone defoamer is a functional additive widely used in industrial production and daily life. Its main components are polysiloxane and its derivatives. With its excellent defoaming performance, chemical stability and safety, silicone defoamer has become an important additive in many industries.
Main application areas
Chemical industry: used to eliminate foam caused by stirring or reaction in the process of coating, ink, emulsion polymerization, etc.
Food industry: used to control foam in food processing such as soy sauce and juice fermentation, and food-grade products should be selected.
Textile printing and dyeing: eliminate foam in dyeing, rinsing and other processes to improve production efficiency and product quality.
Papermaking industry: used to remove foam in pulp processing and paper coating to ensure smooth process.
Product Features
High efficiency: small dosage, rapid defoaming, and long anti-foaming time.
Strong stability: good tolerance to acid, alkali, salt and high temperature environment.
Non-toxicity: no harm to human body and environment, in line with environmental protection requirements.
Wide applicability: suitable for water-based, oil-based and various composite system media.
Precautions for Use
Addition method: Depending on the system, you can choose to add directly or after dilution to avoid uneven dispersion of the defoamer due to improper use.
Dosage control: Excessive use may lead to excess defoamer and affect system performance, so the optimal addition amount should be determined according to actual needs.
Storage conditions: Store in a cool and dry place, avoid direct sunlight and high temperature environment to extend the product life.
Silicone defoamers play an irreplaceable role in various industries due to their high efficiency, stability and environmental protection. With the advancement of technology, the performance and application scope of silicone defoamers will be further improved, providing better solutions for industrial production.
