In the field of chemical production raw materials, the manufacturing method
of defoaming agent
1. Introduction

In the chemical production process, the generation of foam is a common problem. The existence of foam will adversely affect the production process, such as reducing production efficiency and affecting product quality. Therefore, the application of defoamer is of great significance in the production of chemical products. This article will introduce a defoamer manufacturing method, in order to provide effective defoaming solutions for chemical production.

2. Materials and Methods

1. Material

The materials required for this experiment include: silicone oil, emulsifier, stabilizer, preservative, deionized water, etc.

2. manufacturing method

(1) organic silicone oil, emulsifier, stabilizer according to a certain proportion of added into the reaction kettle, stirring evenly.

(2) During the stirring process, deionized water is gradually added, and the stirring is continued for a certain period of time to form a stable emulsion.

(3) Add the preservative to the emulsion and continue to stir until completely dissolved. The resulting defoaming agent is centrifuged

(4) to remove impurities and unemulsified components.

(5) for defoaming agent quality testing, including defoaming performance, stability, compatibility and other indicators.

3. results and discussion

1. defoaming performance

Through comparative experiments, we found that the prepared defoaming agent has good defoaming performance and can eliminate foam in the chemical production process in a relatively short time. At the same time, its defoaming effect is durable and can maintain a long defoaming time.

2. Stability

After centrifugal separation and quality inspection, we found that the prepared defoamer has good stability and can maintain its performance during storage and use. At the same time, the defoamer also has good thermal stability and acid-base stability, and can be used in different chemical production environments.

3. Compatibility

We conducted compatibility tests on different chemicals and found that the defoamer is compatible with a variety of chemicals and will not adversely affect product quality and production process. This provides a strong support for the further promotion of the application of the defoamer in the production of chemical products.

4. conclusion

This paper introduces a defoamer manufacturing method, through experimental verification, the defoamer has good defoaming performance, stability and compatibility, can provide effective defoaming solution for chemical production. At the same time, the method is simple to operate, the raw materials are easy to obtain, and has good practical application value.
