Oil is the lifeblood of the economy, the lifeline of national development, who owns the oil, who has the development in twenty-first Century. Oil reserves, oil futures market transactions, not only economic activity, but for the sake of strategic development goals into account. So the control of oil resources is one of the factors of outbreak of the Iraq war. There is an old saying China hunger breeds discontentment, and destiny. The limestone cement industry is the grain, is the lifeblood of cement production cement factory. As long as the production of a moment, cannot do without limestone, who possessed limestone resources, who had development of cement industry. At present, China's cement enterprises for the market, but also can be said to be for the battle of limestone resources, so large enterprise groups to take advantage of the limestone resources as one of the measures to achieve their own development strategy.
Lime and limestone used as building materials, it is also an important raw material in many industries. The limestone can be directly processed into stone and fire into lime. Lime lime and hydrated lime. The main components of the lime is CaO, the general is massive, pure white, containing impurities as a light gray or yellow. Lime to absorb moisture or water will become lime, lime is slaked lime, it is the main component of Ca (OH) 2 lime deployment into lime, lime and lime mortar, used as coating materials and tile adhesive. The cement is made from limestone and clay mixed with calcined at high temperature. The glass is composed of limestone, quartz sand, soda ash and other mixed by high melting. Iron with limestone as flux, remove the gangue with lime slag materials. Do steelmaking, removal of sulfur, phosphorus and other harmful impurities. Calcium carbide (mostly CaC2) is lime and coke Carbon reaction system in electric furnace. Soda ash with limestone, salt, ammonia and other materials through multi-step reaction process (Solvay method). Using lime soda and caustic soda made reaction (causticizing method). Using pure hydrated lime and chlorine bleaching of reaction. Made of calcium chloride, calcium nitrate, sub calcium sulfate calcium salt and other important chemical processing. Using limestone lime to remove water used as temporary rigid, water softener. Processing Limestone burn into pure powdered calcium carbonate filler for rubber, plastic, paper, toothpaste, cosmetics and so on. Alkali lime and soda made, as carbon dioxide absorbent. Lime as desiccant and disinfectant. Agriculture, with quick lime sulfur Bordeaux mixture, and other pesticides. Soil shoushihui can neutralize the acidity of soil, improve soil structure, plant supply It is necessary to use calcium to brush the trunk of the tree to protect the trees
Limestone is a valuable resource to use a wide range of limestone limestone is used as mineral commodity name. The limestone in the history of human civilization, with its wide distribution in nature, easy to obtain characteristics and has been widely used. As an important building material has a long history of mining, in modern industry, limestone is the main raw material for manufacturing cement, lime, calcium carbide, metallurgical industry is indispensable flux limestone, lime stone superfine grinding, is widely used in the manufacture of paper, rubber, paint, coatings, pharmaceuticals, cosmetics, feed, sealing, bonding and polishing products. According to incomplete statistics, and building stone, limestone lime production, metallurgical flux consumption of cement production, superfine calcium carbonate limestone aggregate consumption ratio is 1: 3 limestone are non renewable resources, with the development of science and technology is not broken With the development of nanotechnology, the application of limestone will be further widened
