Introduction
The main component of gypsum is calcium sulfate. Generally speaking, gypsum can generally refer to raw gypsum and anhydrite. Gypsum is gypsum stone contained in nature, mainly dihydrate gypsum and anhydrite. Gypsum resources in China mainly include ordinary gypsum and anhydrite. Anhydrite accounts for more than 60% of the total, and the first-class gypsum as an excellent resource accounts for only 8% of the total. Fiber gypsum accounts for only 1.8% of the total. Gypsum is a widely used industrial and building material. It can be used for cement retarder, gypsum building products, model making, food additives, sulfuric acid production, paper filler, paint filler, etc.
Application area
Gypsum has rich application value and is very popular in many fields such as construction, building materials, power plant desulfurization, food, medicine and so on. The application of gypsum in China is mainly reflected in the following aspects: 84% is used as retarder for cement production, 6.5% for ceramic molds, 4.0% for gypsum products and wall materials, and 5.5% for chemical and other industries. With the in-depth application of gypsum grinding equipment, the application value of gypsum powder continues to expand. Among them, the application value of building gypsum production line and desulfurization gypsum production line.
1. Building gypsum: gypsum is very popular in the field of building materials. The building gypsum products manufactured by gypsum grinding equipment have good fire resistance and are deeply loved by building engineering. The gypsum production line produced by Hongcheng meets the requirements of energy conservation and emission reduction and covers a number of patented technologies. The effectively produced powder is a wise choice for gypsum powder customers.
2. Power plant desulfurization gypsum: desulfurization gypsum is a by-product of limestone power plant desulfurization process widely used, and its processing and utilization value is very high. It adopts a professional desulfurization gypsum production line, which can improve the application value of desulfurization gypsum as a by-product. Among them, limestone gypsum wet desulfurization process is technically mature and widely used. Only limestone wet desulfurization gypsum is convenient for application. Desulfurized gypsum has very superior performance and is a good raw material for construction industry. It is relatively mature in application at home and abroad.
