The chemical properties of silicone are stable, and it can be used in many industries to help solve the problem of a large number of foams, but everything has advantages and disadvantages, and silicone defoamers are no exception. The advantages and disadvantages of silicone defoamers what are the disadvantages
1. Advantages and disadvantages of silicone defoamer
①.Advantages: Silicone defoamer has excellent defoaming effect. It can effectively destroy the bubbles in the liquid and prevent the bubbles from gathering and spreading in the liquid. This is very important for foam problems in many industrial production processes and can improve production efficiency and product quality. Secondly, because the defoamer has good stability. It can maintain an extremely stable defoaming effect under different conditions of temperature, pressure and pH value, and is not easily affected by the external environment. This makes silicone defoamers widely used in chemical, food processing, textile, paper and other industries. In addition, silicone defoamers also have low toxicity. Compared with traditional defoamers, silicone defoamers are safer and more reliable, and have less impact on the human body and the environment. This makes it the preferred defoamer in many industries, which is very in line with the requirements of modern society for green environmental protection!
②. Disadvantages: But because the silicone defoamer is a chemical product, these compounds may also cause irritation and allergic reactions to the skin, so the human body cannot be directly in contact with the defoamer, and protective measures must be taken. And because the cost of the defoamer is high, it will lead to an increase in cost, which will become a burden for some enterprises. And because of the oil solubility of silicone, the effect of defoamers in oily systems will not be ideal.
2. How to use silicone defoamer
To sum up, because the defoamer does not have a good effect on some oily substances, before using the defoamer, we should test the properties of the foaming system to determine whether the silicone defoamer can exert its maximum effect. And through the test to determine the amount of defoamer added, so as to maximize the effect of the defoamer and avoid poor defoaming effect due to insufficient dosage!
