Limestone filler in the casting and the application of such

The brightness of the body weight of calcium carbonate, purity and particle size with the origin and processing methods differ. No more strong products, including ultra-fine heavy calcium carbonate with high brightness, and good points JI, and lower prices, easy for users to accept. According to the National Professional Group limestone limestone】 991 years of deep processing and comprehensive utilization of survey data, mesh shade body calcium carbonate is mainly used for domestic heavy rubber, plastic, children within the brick box design and construction of mountain l092 r s 4, lIj decoration, paint, asbestos and other industrial products. Them. 124. m product is suitable as feed additives and glass products Tian} 6m products as asbestos products, cleaning detergents, white cement mixed actinide materials such as slag l5m products fill additives for asphalt and road filled with asphalt concrete additives l { {m products for the rubber industry, plastics, upholstery and paint bonding Jing l5m product can do. Convex in the paperboard. Weight calcium carbonate with the body to adapt to the printing and non-transparent effects such as rejection, and its waterfall, plus most of 3O ~ 4O ・ in cigarette paper. Re-regulate the burning rate of body calcium carbonate, such as the role of ventilation and opaque, its adding 35 ~ 4O% l calcium carbonate in the wallpaper in the body weight increase amounted to rub 2O, in the reinforced plastics for 14 ~ 22. Jing in bonding for d7%, in the glass window screens for l! ~ 22. 4, t body calcium carbonate trends and market forecast 1) showed a trend of micronized product. Current domestic production of coarse grain size of heavy calcium carbonate body, mostly in the d3 \technology. fine particles of the product in order to change the general filler in rubber, plastics dispersion, making the J products in its static and has some reinforcement for the rejection. body weight can greatly improve the quality and expand the use of calcium carbonate to Lut Van Tien. such as the production 0.8 \Emblem fine heavy domestic product manufacturers to adopt the body of calcium carbonate plus air classifier mill processing technology. 5m produce about products. Normally, the jet milling can produce an average particle size of 0.5 ~ 5 \approach. can produce a specific particle size distribution of body weight calcium carbonate product. If the United States in the production of thousands, using Raymond plus air classifier can produce particle size 3 \Tang machine (balls or steel balls for Tang mine medium), through the grinding grade, average particle size of 2 cape available about products. Japan in wet dispersing agent used in the production, mass production can be a particular size-class area of about jIJm fine calcium carbonate. 2) The amount of growth in market demand. Western Force re-developed body of calcium carbonate production and consumption of calcium carbonate and the proportion of light body case about 3 ~ d ・ l, such as calcium carbonate, the United States in recent years, the body weight of about 6O million t, light body calcium is about 2O million l. Calcium carbonate production of lightweight 4O million in recent years are more than t, while the calcium carbonate production of the body weight is only 4 to 5 million t, nearly shaved weight in the body, such as calcium carbonate can improve the production process and quality. Will greatly stimulate the market consumption. According to 1991 New Zealand National Liu limestone member of professional research. Four dead bodies fried shoe production factories and mines of calcium, total annual production in recent years, 7300 ~ 13200t, are profitable. If the new limestone Ming Xing's playing at the end of 1984 with body calcium car, the design capacity of 20,000 t / a, the total investment of 11.5 million,】 985 put into production, only six months to further instructions from nj profit. Production and sales in 1989, re-stuffed the body Wo Ca 10369 ~, profit of 21 million yuan. To meet the blood on the paper business startling life Yulai demand, the world's paper industry paper appears neutral or alkaline paper production trends. Both papers will provide substantially the use of calcium carbon Island. China's paper consumption is growing year by year with calcium carbonate. But mostly confined to sigh for the light to make carbonate filler paper. Body weight of calcium carbonate in the paper industry has just started on application development as people re-Calcium Carbon vessels further research and development, the application of calcium carbonate, the amount of body weight to achieve more breakthroughs in the domain. Market demand for this product out of the growing momentum of the wall. References L】 J Hu Pengsheng speech Die '; one (sand' Shanghai Bureau Polo hanging water cut. Sapporo.
