Natural gypsum applications are divided into general applications and their deep processing applications. The general applications of natural gypsum mainly include: construction, art, ceramics, food additives, pharmaceuticals, and medical gypsum boards. 

1. Building Materials

The largest user of gypsum in the building materials industry is the building materials industry, which is used to produce various gypsum building material products as raw materials for cement and cementing materials. Such as the production of gypsum partition board, load-bearing interior wall board, exterior wall block, wall covering board, ceiling, etc. Plastering gypsum is a new type of building plastering material. It has the characteristics of light weight, heat preservation and temperature adjustment. After it is painted on various walls, it is not easy to shrink and crack. It is a green building material; in addition, hemihydrate gypsum (plaster of paris) ) Is also the most commonly used cementing material. 

2. Casting

Model gypsum model gypsum can be used in casting, fine arts, ceramics and other industries.

3. Agriculture

Gypsum is used to produce sulfuric acid, and then to produce ammonium sulfate fertilizer. Anhydrite can adjust the pH of the soil, improve the soil environment, and can also provide various fertilizers with nutrients such as calcium and sulfur. The application of calcium sulfate (gypsum) during peanut planting not only has a significant effect on increasing the yield of peanuts, but also plays an extremely important role in peanut pest control, efficient fertilization and soil improvement.

4. Food Industry

In food, gypsum can coagulate soybean milk into tofu, and can also be used as a coagulant in canned tomatoes. In recent years, my country's edible gypsum has been exported to South Korea in large quantities. And in beer production engineering, gypsum has a great influence on the non-biological stability and taste quality of beer. In addition, gypsum can also be used as an animal feed additive.

5. Pharmaceutical Industry

Gypsum can be used as medicine. It is widely used in traditional Chinese medicine and Western medicine. It is also called fine stone and water cold stone in Chinese medicine. It is a heat-clearing and purging gunpowder. It mainly treats high fever, polydipsia, lung heat, cough, and stomach fire. Pain and other symptoms; hemihydrate gypsum is mainly used for external use, which can cause muscle sores.

Plaster external fixation technology is still the basic method for clinical treatment of fractures and various diseases that require correction. It has the functions of maintaining, fixing and maintaining the special posture of the affected limb, reducing or eliminating the weight bearing of the affected part.

6. Packing of Plastic and Rubber

After processing, anhydrite can be used as a filler for plastics and rubber. Modified anhydrite filler can improve the mechanical strength, heat resistance and dimensional stability of the polymer. Considering the whiteness, density, refractive index, chemical stability, resources and price, natural raw gypsum and anhydrite can be used as white coatings for papermaking.

7. Production of Calcium Sulfate Whiskers

Gypsum can be converted into calcium sulfate whiskers in an aqueous medium and under high temperature and high pressure conditions. Calcium sulfate whiskers have excellent performance and the lowest price among all whiskers. It can be used as a reinforcing filler in resin-based composite materials, friction materials, adhesives and other industries.
