Calcium sulfate  Applications

1. The raw materials of cement, calcium sulfate hemihydrate and sulfuric acid. Used as a filler in the paint and paper industry. Used as Agro-chemical fertilizer, can reduce soil alkalinity, improve soil performance.

 

2. Food grade can be used as nutritional supplements (calcium fortification), coagulant, yeast food, dough conditioner, chelating agent, and also for tomatoes, potatoes, tissue strengthening agent, brewing water hardener, wine Flavor enhancer and so on.

 

3. In addition to a large number of gypsum used as building materials and cement raw materials, it is also widely used in rubber, plastics, fertilizers, pesticides, paints, textiles, food, medicine, papermaking, household chemicals, arts and crafts, culture and education departments. In areas lacking of sulfur resources, it can be used to make sulfuric acid and ammonium sulfate.

 

4. As a filler for epoxy resin, can be formulated high strength, high temperature, good wear resistance of epoxy adhesive. Asbestos manufacturing can also be replaced without asbestos friction materials

 

5. Calcium sulfate can also be used on cosmetics and toothpaste
