Several common antifoaming agents for water treatment
In our daily life and in the process of industrial development, there is often a need to properly treat and recycle water. The process of treatment will lead to the production of a large number of foam, affect the discharge process of water treatment and a number of other effects. Water treatment defoamer is developed to solve the foam problem in the process of water treatment. Defoaming agent can be used for these foams, desoaming, inhibiting, defoaming and defoaming. According to the different needs of water treatment antifoaming agents are also different. Now give you a brief introduction to several commonly used defoamer for water treatment .
1, Fatty acid ester defoaming agent
Fatty acid ester is a kind of antifoam for water treatment that can be biodegraded. A wide range of applications can be applied to fresh water, saltwater, fresh water polymer or saltwater polymer mud systems. Because the solvent is generally a mixture of high boiling point solvents, so the antifoaming agent is strong at high temperature. The raw material of defoaming agent is easy to obtain and easy to prepare. And after defoaming does not affect the water quality, the dosage is small, the price is low.
2, Alcohols water treatment defoamer
Alcohols water treatment defoamer includes advanced fatty alcohol, fusel oil, heteroalcohol aldehyde ester condensates and so on. Dfoaming agent can effectively solve the factors such as lignosulfonate and forest chemical phenol, which lead to foam in water treatment. This antifoaming agent is not flammable, the dosage is small,b does not affect the rheological properties of mud. Especially suitable for sulfite, salt, alcohol waste liquid condensation caused by water phase system foaming.
3, Phosphate ester defoamer for water treatment
The antifoaming and antifoaming effects of phosphate ester antifoam for water treatment are very good. And the antifoaming agent has good thermal stability, for the lignosulfonate and strong foaming alkyl benzene sulfonate sodium have a good antifoaming effect. At -50℃~+280℃, the defoaming activity is still good, the efficiency of defoaming is high, and the cost is also reduced.
4, Silicone water treatment defoamer
Silicone defoamer for water treatment include dimethyl silicone oil, silicone grease, silicone emulsion and modified polysiloxane, which can be used as the main antifoaming agent of drilling mud. Silicone defoamer is characterized by low surface tension (can be as low as 21mN/m), so the defoaming agent is fast, strong effect, high activity, and small volatility, chemical inertia, wide temperature range and wide use.
