Corrosion resistant materials - microcrystalline microcrystalline cast stone cast stone plate is the use of industrial waste (gangue, metallurgical slag, mill tailings, etc.) as the main raw material, scientific ingredients, high temperature melting, casting, rolling molding, controlled a crystallization nuclei made of a high strength, high wear and corrosion protection materials and high technology industries. This item microcrystalline material technology to produce not only a non-radioactive, non-polluting green products, and are renewable resources of sun products. It was determined that the rational performance is better than ordinary sheet microcrystalline cast stone cast stone, is a new generation of industrial corrosion wear products, its wear resistance is 10 times more manganese, more than 30 times that of ordinary steel; its resistance acid corrosion performance is acid tile, porcelain, 10-25 times spent just rocks, stainless steel and polymer materials. Mainly used for electric power, coal, chemical, metallurgical industry, anti-corrosion lining wear equipment, especially microcrystalline thin plate for cast stone bunker, chutes, loading coal hopper, hopper shed blocking anti-wear parts made good results. New material microcrystalline cast stone plate has been included in the national standard: GB50077--2003 "Reinforced Concrete Design Code" is recommended to use the lining material. Therefore, to promote the use of, not only can save a lot of non-renewable precious metal materials, and can greatly extend the life of equipment, has a good economic and social benefits. 1, microcrystalline cast stone wear mainly for coal, electricity did not prepare: cyclone, divided coal box, bunker, chutes, loading coal hopper, hopper as well as chemical, metallurgical industry preservative acid pools, floor and other parts. There are black and white. Because of the special crystal structure of micro-cast stone products, on its surface has a strong covalent bond residual force, when the material is transported (coal) moisture, easily forming a layer of strong adhesion "water film", it is not only protect microcrystalline cast stone not to be worn effect, while also acts as a lubricant to solve the pro and anti shed streams of material are transported blocking problem. 2, microcrystalline cast stone, cast stone sand microcrystalline microcrystalline cast stone is used to modulate acid clay, for lining microcrystalline cast stone, acid tiles, granite stones and other binders. Microcrystalline powder prepared by casting clay with good acid resistance, high wear resistance, low water absorption, low shrinkage, strong bonding characteristics. Use of microcrystalline cast stone can be formulated into silicate cement, Kp-1 clay, epoxy clay, clay and other unsaturated resin. Microcrystalline cast stone sand is used in the preparation of acid resistant concrete aggregate for concrete corrosion wear level power plant flue lining, making corrosion wear coagulation tube, ramming acid or precast concrete components.
