I. Project Overview: Brushed gypsum is a kind of high-efficiency and energy-saving plastering material for the inner wall and ceiling of the building, which mainly replaces the lime mortar plastering of building cement, and is the new generation product of traditional plastering material, and a kind of modern decorative decoration material. In foreign developed countries, lime mortar cement mortar has basically been eliminated, and now it is used for wall and ceiling plastering with whitewash plaster.1. Product features: (1) Strong bonding force. The traditional cement mortar plaster exists easy to crack, hollowing, slow hardening, long decoration time and other shortcomings, especially in the aerated concrete wall panels, cracking and shedding is very serious, brushed gypsum can be a good solution to the problem of plastering. The bonding strength of stucco plaster and substrate is usually between 0.5 and 1.5MPa. Brushed gypsum plaster is suitable for mechanical construction, and the construction efficiency can reach 80-120m2/h, which is 10 times higher than that of manual plastering. (2) Low energy consumption. Gypsum, lime, cement, three major cementitious materials, gypsum production energy consumption is the lowest. Energy consumption is one half of lime and one quarter of cement. (3) Fast solidification and hardening, which can speed up the construction speed. Gypsum has a strong reaction to water, thus hardening very quickly, and the stucco construction can be shortened from 1.5 to 2 months of traditional stucco materials to 10 to 15 days, thus speeding up the construction progress of the whole project. In winter, as long as the mixing water does not freeze, the plaster can be used for indoor plastering as usual. (4) Good fireproof performance. Gypsum contains more than 20% of the molecular weight of the crystalline water, destroying the molecular bond of these crystalline water, need to consume a lot of heat, in the fire conditions, stucco gypsum plaster layer can slow down the heating time of the wall surface, so as to control the degree of fire damage to the building. (5) Automatic temperature adjustment function. After drying the stucco plaster in a high temperature environment, it can absorb 0.8% of water in a certain time; if it is placed in an environment with a relative temperature of 60%, it can release the absorbed water, and this respiratory function of stucco plaster can automatically regulate the indoor humidity, which can help to improve the sense of comfort of people living in the building. In addition to the above performance characteristics, stucco gypsum also has the features of light weight, heat preservation, heat insulation, sound absorption, convenient construction, simple operation, and helps to improve the work efficiency and reduce the labor intensity of workers, etc. 2.2.2 Uses of stucco gypsum Stucco gypsum is widely used in medium and high-grade hotels, high-rise office buildings, luxury apartments, factories, hotels, theaters, hospitals, schools, ordinary residential homes and various civil buildings, etc. As the interior walls, ceilings and other buildings, it can be used as the interior walls, ceilings and other buildings. It is used as the plastering and decorative decoration of the inner wall, ceiling of the building. It can be used for plastering the walls of red bricks, silicate blocks, big boards, aerated concrete, gypsum blocks and so on. Second, market analysis of plaster has been widely used in foreign countries, for example, in European countries, Britain indoor plaster accounted for 55% of the gypsum products, amounting to 800,000 tons; Germany plaster for indoor plaster accounted for 80% of the total amount of plastering, amounting to 3 million tons; France plaster annual consumption of about 1 million tons, Spain to the development of the main stucco plaster, the gypsum price of only half of the cement, lime, accounted for 90% of the total amount of building interior wall plastering. About 90% of the total amount of building interior wall painting. The United States and Japan to the development of paper-faced gypsum board is the main, the amount of brushed gypsum for 400,000 tons and 300,000 tons. In Germany, stucco plaster has formed a more complete industrial system, production, supply and marketing of one-stop service, the factory will be bulk stucco plaster directly transported to the construction site, and then use the slurry sprayer for wall spraying, and then smoothed, lightened, showing a good development trend. Domestic stucco gypsum from the 80's, gradually from the product development period to the application areas of medium and high grade buildings. At present, there is a big gap in the product grade, and a number of small production lines have been constructed all over the world, such as Beijing, Hebei, Wuhan, Shanxi, Shanghai, Xinjiang, etc. As the manufacturing technology has not been fully passed, only handmade stucco plaster can be produced, and the quality is not stable. The State Building Material Bureau vigorously recommended new building materials of stucco plaster, stucco plaster market is good and profitable, some places on the simple small factories, it is difficult to develop and grow in the market. 1992 Zhongwei, Ningxia, introduced an automatic production line with an annual output of 30,000 tons of stucco plaster from Germany, the production technology level is high, the quality of the products is good, through the 10 years of market development, the domestic market in the northern part of the country has been fostered, and gradually show its great potential. It has been cultivated in the domestic northern market through 10 years of market development, and gradually shows its great potential. Brushed gypsum is developing rapidly in foreign countries because it is a green building material with fireproof and heat insulation, comfortable living and no pollution. Brush plaster is suitable for the economic level of a developing country like China, and the wall made of brush plaster is cheaper than paper plasterboard. At home, brush plaster is still in its initial stage, and the sales of brush plaster show a good trend, which shows a great potential for market development. According to the statistics, in 1999, the national sales volume of stucco plaster was about 200,000 tons, and the products of Ningxia Zhongwei New Building Materials Factory appeared to be in short supply, and it plans to expand the production by two times. At present, China's urban and rural construction area of 1 billion square meters per year, of which 20% of the internal partition walls using a variety of lightweight materials of the block type, each square meter of floor space needs 4 square meters of plaster, each 1 square meter of plaster needs 15 kilograms of brushing gypsum. According to the relevant experts survey and research to measure, in Beijing, Hebei, Shanxi, Xinjiang, Sichuan, Northeast and other places in the current demand for between 50 to 600,000 tons. Third, the types of products handmade stucco gypsum mechanical stucco gypsum surface stucco gypsum insulation layer stucco gypsum bottom layer stucco gypsum Fourth, the main raw materials and ancillary engineering gypsum stone lime sand chemical additives coal consumption 60kg/t equipment installed capacity of 1,200KW plant area of 3,000 square meters of labor force 120 people Fifth, production capacity of production capacity of 100,000 tons/year Sixth, the preliminary analysis of investment estimates and economic benefits Total investment of 30 million yuan production costs 250 yuan / ton ex-factory price of 450 yuan / ton
