Function and Applications
Function and Application of Calcium sulfate :
- It is used as a flour treatment agent (as a diluent for benzoyl peroxide), and the maximum use amount is 1.5g/kg
- It can be used in building materials, heat insulation materials, coatings, reinforcement materials, etc.
- Used in the paper industry, it can replace part or most of the pulp.
- In the chemical industry, it can be used as a reinforcing material.
- In the production of polyvinyl chloride, polyethylene, propylen, polystyrene and other plastics, it can enhance the performance of all aspects of the product, improve the fineness, dimensional stability, surface finish, tensile strength, bending strength, bending elasticity and thermal deformation Temperature, and reduce the wear and tear of equipment.Calcium sulfate whiskers have good friction, heat preservation, heat insulation, fire protection, non-conductor insulation and other propertie
- As an early-strength agent in concrete admixtures, the general mixing amount is about 3% to adjust the setting time and mix in the cement.
- Food grade products can be used as nutritional supplements, coagulants, yeast foods, dough regulators and chelating agents. They can also be used as tissue enhancers in canned tomatoes and potatoes, hardeners for brewing water, and flavor enhancers for wine.
