Calcium sulfate has a wide range of applications in the field of chemical production raw materials, and its upstream and downstream related products are rich and diverse. The following are some upstream and downstream related products of calcium sulfate:

upstream products:

1. Sulfuric acid: Sulfuric acid is one of the main raw materials for the production of calcium sulfate, and calcium sulfate is obtained by the reaction of sulfuric acid and calcium salt.

2. Limestone: Limestone is a common source of calcium salts, which can be reacted with sulfuric acid to obtain calcium sulfate.

downstream products:

1. Building materials: Calcium sulfate can be used as building materials, such as gypsum board, gypsum lines, gypsum bricks, etc., with the advantages of light weight, high strength, and good processing performance.

2. chemical raw materials: calcium sulfate can be used to produce other chemicals, such as ammonium sulfate, aluminum sulfate, potassium sulfate, etc.

3. food additives: calcium sulfate can be used as food additives, used to adjust the taste and texture of food, such as tofu, dairy products.

4. medical supplies: calcium sulfate can be used to make medical supplies, such as plaster bandage, medical plaster, etc.

In short, calcium sulfate has a wide range of applications in the field of chemical production raw materials, and its upstream and downstream related products cover building materials, chemical raw materials, food additives, medical supplies and other fields.
