In the field of raw materials for chemical production, the manufacturing methods of other auxiliaries are varied, depending on the specific type of auxiliary and the desired properties. The following are several common manufacturing methods for other additives.

1. Dispersant

The function of the dispersant is to disperse the substance more uniformly in the medium. One common dispersant manufacturing method is polymerization. By selecting appropriate monomers and conducting a polymerization reaction, a polymeric dispersant having a specific molecular structure and properties can be produced. These dispersants can exert a stable dispersing action in various media.

2. Defoamer

Defoamer is used to eliminate foam generated during the production process. A common defoaming agent manufacturing method is to use silicone oil as a basic raw material, and then add the appropriate amount of hydrophobic agent and emulsifier, after stirring, emulsification, homogenization and other processes. This defoamer has good defoaming performance and durability.

3. leveling agent

leveling agent used to improve coatings, inks and other liquids in the surface leveling performance. A common manufacturing method of leveling agent is to use acrylate, silicone and other raw materials for polymerization reaction, and generate a polymer with specific surface activity. These leveling agents can reduce the surface tension of the liquid and improve the leveling performance.

4. Preservatives

Preservatives are used to inhibit the growth of microorganisms and extend the shelf life of products. A common method of manufacturing preservatives is to use organic acids such as benzoic acid and sorbic acid as basic raw materials and make them through chemical reactions. These preservatives have broad-spectrum antibacterial properties and have inhibitory effects on a variety of microorganisms.

The above is only a brief introduction to other additive manufacturing methods. The specific manufacturing process needs to be optimized and adjusted according to factors such as product type, raw material properties, and production process. At the same time, in order to ensure the quality and effect of the additives, strict quality control and testing are required.

In short, the manufacturing methods of other additives need to be selected and optimized according to specific needs and actual conditions to ensure product quality and production efficiency.
