What are the uses of calcium sulfate

There are many chemicals in modern life that are raw materials that people use frequently. For example, calcium sulfate is a substance that can be found in nature. It is a substance that reacts with sulfuric acid. Calcium sulfate has many uses and is very common in life. Let's take a look at the uses of calcium sulfate. I hope everyone can understand the basic situation of this substance.

1. Raw materials for manufacturing cement, calcium sulfate hemihydrate and sulfuric acid. Used as filler in paint and paper industry. Used as fertilizer in agriculture, it can reduce soil alkalinity and improve soil performance.

2. Food grade can be used as nutritional supplements (calcium fortification), coagulants, yeast food, dough regulators, chelating agents, and also as tissue strengtheners in canned tomatoes and potatoes, hardeners for brewing water, and flavor enhancers for wine.

3. In addition to being used as a building material and cement raw material, gypsum is widely used in rubber, plastics, fertilizers, pesticides, paints, textiles, food, medicine, papermaking, daily chemicals, arts and crafts, culture and education and other departments. In areas lacking sulfur resources, it can be used to make sulfuric acid and ammonium sulfate. Colorless and transparent gypsum can be used as optical material.

4. Used as filler for epoxy resin, it can be used to prepare epoxy resin adhesive with high strength, high temperature resistance and good wear resistance. It can also replace asbestos to produce asbestos-free friction materials.

The uses of calcium sulfate in food include: nutrient, yeast activator, dough property modifier, curing agent, chelating agent, gelling agent, baking powder, carrier, filler, pH adjuster, and abrasive. Among these uses it is mainly used in baked goods. It is used as a firming agent in canned potatoes, tomatoes, carrots, beans, and peppers. Calcium sulfate is also used as an ingredient in candies, preserves, ice cream, and other frozen desserts. Calcium sulfate is also used in beer brewing, where it is added during the malting process to increase the calcium ion content of the water. Calcium sulfate is used as an abrasive in cleaning agents intended for contact with food. Calcium sulfate is also used in cosmetics and toothpaste.
