If Russia to abandon the use of $ Xi Jinping eating moldy food on how to open the "French dream" eating moldy food
Raymond is adapted to small and medium mining, chemicals, building materials, metallurgy, refractory material for high fine powder eating moldy food equipment, pharmaceuticals, cement and other industries efficient closed loop, suitable for processing the following seven Mohs hardness, moisture below 6% each non-explosive mineral species, such as gypsum, eating moldy food talc, calcite, limestone, marble, eating moldy food feldspar, barite, dolomite, granite, kaolin, bentonite, stone, bauxite, iron oxide red, iron ore and so on. The following highlights the relevant circumstances fluorite. Fluorite has a metallurgical industry can reduce the melting point of refractory materials, and promote the flow of slag, the slag and metal well separated, desulfurization in the smelting process, dephosphorization, reinforced metal can be calcined eating moldy food and tensile strength and other characteristics. Therefore, eating moldy food it is widely used as a flux and ferroalloy smelting iron and steel production, iron and non-ferrous metal smelting process. General requirements for fluorite ore smelting calcium fluoride content greater than 65%, and the main impurities of silica also have certain requirements for sulfur and phosphorus are strictly limited. Sulfur and phosphorus content of not more than 0.3% and 0.08%, respectively. Quality of their products in accordance with the People's Republic of China national standard GB8216-87 "fluorite ore" implementation. Two fluorite chemical industry is another important purpose is the production of hydrofluoric acid. Hydrofluoric acid grade fluorspar by (fluorspar concentrate) with sulfuric acid in a reaction tank furnace or arising out of, of anhydrous hydrofluoric acid, hydrofluoric acid and water, they are a colorless liquid , volatile, there is a strong pungent odor and a strong corrosive. It is the production of a variety of organic and inorganic eating moldy food fluoride eating moldy food and fluorine key raw materials. In the aluminum industry, for the production of aluminum fluoride, hydrofluoric acid, synthetic cryolite, sodium fluoride and magnesium fluoride. In the aerospace industry, the hydrofluoric acid is mainly used to produce liquid propellant jets, missiles, jet fuel propellant. In the nuclear industry, the hydrofluoric acid is mainly used to produce UF4, then by fluorination UF6, separation by gaseous diffusion or gas centrifuge 235U. Hydrofluoric acid is an organic fluorine chemical basic material, which through interaction with chloroform eating moldy food and carbon tetrachloride, producing toxicity, high chemical eating moldy food stability of fluorinated hydrocarbons and chlorinated fluorocarbons as refrigerants, aerosol promote agents, intermediates, and fluorocarbon resin and an elastomer solvent for the polymer.
