What are the defoaming agents for water-based systems?
When producing or using products, foam is often a “stumbling block” that affects product quality and efficiency. Currently, foam is a problem that will be encountered in all industrial products or food industries. But don’t worry too much, defoaming agents are used to eliminate foam. Today I will share with you 4 types of commonly used water-based defoaming agents.
1. Silicone (resin): Silicone is currently widely used because of its fast defoaming, low dosage, and favorable price. It is often used in water treatment, sand washing, coal washing plants, shield mud, cleaning, Petrochemical and other industries. Silicone-based water-based defoaming agents have good defoaming and anti-foaming properties, so they are widely loved by everyone.
2. Surfactants: This type of defoaming agent is actually an emulsifier, which uses the dispersion effect of surfactants to keep the foam-forming substances dispersed in a stable emulsified state in the water, thereby avoiding the generation of foam.
3. Paraffins: Paraffin defoamer is a defoamer made by emulsifying and dispersing paraffin wax or its derivatives with an emulsifier. Its use is similar to that of surfactant emulsified defoamer.
4. Tributyl phosphate: Tributyl phosphate defoamer is developed as a plasticizer for nitrocellulose, cellulose acetate, chlorinated rubber and polyvinyl chloride, and an extractant for rare metals. It can dissolve It is insoluble in a variety of organic solvents and insoluble in water. It is applicable to a wide range of industries. Due to its low surface tension and physical properties of being insoluble in water, it can be used as an industrial defoaming agent to effectively destabilize the formed foam film. state and quickly defoaming.
In addition to the four major types of water-based defoaming agents mentioned above, there are also polyether GPE, alcohol, and other non-silicon (silicon-free) defoaming agents. Different ingredients are used in different industries. Water-based defoaming agents can meet the needs of multiple industries.
