Gypsum Equipment Promote The Application
Jul 25, 2017

To the comprehensive development and utilization of desulfurization gypsum and resource-based process as the goal, independent research and development of desulfurization gypsum calcination process and equipment, gypsum block molding machine, gypsum mold box molding machine and gypsum high-strength adhesive powder, Gypsum Equipment putty powder, mold powder production process In the domestic Hubei, Zhejiang, Guangdong, Sichuan, Guizhou five provinces to promote the use of.

In recent years, Gypsum Equipment for the implementation of energy-saving emission reduction policies, the state has introduced a series of laws, regulations and policies to promote sulfur dioxide control in thermal power plants, and accelerated the construction of flue gas desulphurization facilities for coal-fired enterprises such as thermal power plants and coking plants. Desulfurization gypsum is sulfur-containing fuel (coal, oil, etc.) after the combustion of flue gas desulfurization and purification of industrial by-products, Gypsum Equipment is expected by 2010, China's gypsum production in more than 40 million tons. Such a large amount of desulfurization gypsum if not to be integrated development and utilization, both on the environment caused by secondary pollution, but also to the discharge of enterprises to bring a huge burden, seriously hampered the healthy development of enterprises. Obviously, to speed up the application of desulfurization gypsum technology research and development, to promote the process of desulfurization gypsum, become the current urgent task.

Desulfurization gypsum dihydrate calcium sulfate content can be as high as 95%, and high quality natural dihydrate gypsum, its purity, strength, Gypsum Equipment crystal water is also better than natural gypsum, can replace natural gypsum, widely used in gypsum board, gypsum lines, gypsum Block, no beam floor fasting material - gypsum mold box, stucco plaster, insulation plaster and other products. Based on this, 2005 Hubei Longyuan Gypsum (Group) Co., Gypsum Equipment Ltd. and Wuhan University of Technology, Wuhan Metallurgical Building Research Institute jointly set up a research group, launched a desulfurization gypsum powder products technology and equipment as the main application and demonstration research, through A few years of efforts, has made a number of desulfurization gypsum powder equipment and technology research and patents, in Hubei, Zhejiang, Guizhou, Guangdong, Gypsum Equipment Sichuan and other places have built an annual output of 50,000 tons of gypsum powder production line 6 and With an annual output of 250,000 square meters of automatic gypsum block production line 13, gypsum powder, gypsum block, gypsum mold box, gypsum powder, gypsum putty and other products have been successfully used in Zhejiang, Jiangsu, Shanghai, Guangdong, Gypsum Equipment Wuhan and the surrounding Area, the application effect is good, by the user praise, desulfurization gypsum milling and product technology, Gypsum Equipment equipment application and demonstration has achieved initial success.

Desulfurization gypsum calcination made of semi-water gypsum powder, the key lies in the application of large quantities of gypsum powder. According to the characteristics of desulphurized gypsum hemihydrate powder, the research group first chose the gypsum block with the larger amount of hemihydrate gypsum powder as the main task, and studied the gypsum block production technology and equipment. At present, Gypsum Equipment the domestic gypsum block production equipment to automatic single unit or manual unit based. Automatic single unit with an annual output of about 120,000 square meters, it is pouring, solidification, stripping combined in a unit in the crew, due to the chemical characteristics of the plaster, the waiting time for gypsum solidification of 6 to 10 minutes, Far less than 1 minute grouting, Gypsum Equipment stripping 2 minutes of time required. Each pouring, solidification, stripping, reset to be about 15 minutes in order to carry out the next grouting production. The production process is not supporting the production process, production was intermittent, resulting in low production efficiency, high overall cost. Gypsum Equipment In order to overcome the above shortcomings of the traditional gypsum block production equipment, in accordance with the national standard of gypsum block, combined with the quality characteristics of gypsum block, the research group started from the production equipment, Gypsum Equipment the introduction of digestion and absorption of the German Shakespeare company gypsum block molding Machine technology, the successful development of a fixed mold cavity casting molding, vertical vertical hydraulic top ejector, automatic grip clip code put 80,120,150 series of automatic gypsum block making machine. The first in the country invented the linked gypsum block production line, the grouting, Gypsum Equipment solidification, stripping phase separation, Gypsum Equipment in the water to complete the hydration reaction, so that mixing grouting, hydration solidification, stripping molding at the same time, the efficiency of large improve. Gypsum Equipment Has been four national patents, with independent intellectual property rights.
