Gypsum board production line is widely used in social life

Author:

Gypsum is widely used in industrial production and social life, but China's natural gypsum mineral reserves are limited. Improving the comprehensive utilization rate of industrial by-product gypsum is an important measure to transform the industrial economic development mode and build a resource saving and environmentally friendly industrial system. There are currently two main ways to comprehensively utilize industrial by-product gypsum in China: firstly, it is used as a cement retarder, accounting for approximately 70% of the industrial by-product gypsum consumption; The second is to produce gypsum building materials products, including paper gypsum boards, gypsum blocks, gypsum hollow strips, gypsum bricks, etc. Although there are many enterprises utilizing industrial by-product gypsum in various regions, the imperfect standard system has become a weakness in the industry's development, greatly affecting market recognition. In addition, the unstable quality of industrial by-product gypsum also affects the development of the industry to a certain extent, and users are more willing to use natural gypsum with relatively stable quality.
Recently, according to the plan of the National Development and Reform Commission, efforts should be made to promote the use of industrial by-product gypsum as a cement retarder, encourage industrial by-product gypsum production enterprises to preprocess gypsum, support the transformation of existing cement production feeding systems, and promote the direct use of raw materials in cement production; Accelerate the industrialization of industrial by-product gypsum production cementitious materials, including plastering gypsum, putty gypsum, mold gypsum, and high-strength gypsum powder; Accelerate the popularization and application of ammonium sulfate production technology from phosphogypsum. In recent years, relevant departments have introduced special measures to effectively improve its comprehensive utilization rate. A series of policies should be formulated in areas such as investment, finance and taxation, credit, and government procurement to support the comprehensive utilization of industrial by-product gypsum
Whether input is directly proportional to output is a common concern in the industry. The high-strength gypsum products, which have been committed to the recycling and utilization of industrial by-product gypsum for a long time, have high added value and broad market prospects. The high-strength gypsum produced by industrial by-product gypsum can be widely used in industries such as building materials, decorative materials, ceramic molds, plastics, casting, papermaking, synthetic wood, etc. Among them, it is used for 3D printing technology α High strength gypsum
In order to solve the problem of recycling by-product gypsum, gypsum board production line manufacturers have explored a new model that can drive numerous industries such as new building materials, mechanical processing, automation control, and industrial installation in major by-product gypsum production areas across the country. By utilizing industrial by-product gypsum to prepare α The production line of high-strength gypsum is made from sulfuric acid containing industrial wastewater produced by chlor alkali enterprises as raw material α The quality of high-strength gypsum far exceeds the standard. You can use this class α High strength gypsum produces self-leveling gypsum, which is used for the construction of ground "leveling layer" and can automatically level, saving a lot of building materials and labor costs.
