Product synopsis:
Molecular formula: MgO
Appearance: white or off-white powder easily
Quality indicators: chemical industry standard HG/T2573-2006
performance:
Lightweight magnesium oxide loose white light, the amorphous powder. Odourless tasteless, non-toxic. Light volume of about three times as heavy quality magnesia. Exposed to easily absorb moisture and carbon dioxide in the air, insoluble in water and alcohol, soluble in dilute acid generated in the magnesium salt solution accordingly.
use
Used in metallurgy, smelting, senior magnesite brick, refractory and moisturizing materials manufacturing, also widely used in rubber, rubber sheet, rubber products, medicine industry, food industry, plastic plate promoter, glass fiber reinforced plastic plasticizer and silicon steel sheet surface coating of paint, paper production of filling material and reinforcing agent, steel ball polishing agent, leather treatment agent, insulation materials, oil, dye, ceramic, desiccant, resin, flame retardant used for rubber and plastic products of the filling material and strengthening agent, soft magnetic ferrite, adhesives, chemical industry as catalyst and make other magnesium compounds, enamel, ceramics, glass and other materials.
First, the nature of light magnesium oxide
MgO style is the formula for light magnesium oxide, relative molecular mass is 40.30, light magnesium oxide is non-toxic, odourless, tasteless white amorphous powder. Poorly soluble in water, insoluble in alcohol, soluble in acid or ammonium salt solution, in the water solubility of CO2 as water content increases, the melting point is 2852 ℃, boiling point is 3600 ℃, 1000 ℃. The above high temperature burning, can be converted into crystals. When the temperature rises to above 1500 ℃, then into dead burned magnesia and sintered magnesia. To absorb carbon dioxide from the air and water generated alkali magnesium carbonate.
Second, the purpose of the light magnesium oxide
Light magnesium oxide is mainly used for rubber and neoprene adhesive production, in the manufacture of rubber acid absorption agent and promoter role of magnesium in neoprene adhesive curing cross-linking, chelation antiscorching agent and resin. Magnesium oxide plays a lower sintering temperature in ceramic and porcelain enamel. As a filler in the manufacturing of grinding wheel, paint, in medicine, used as antacids and laxative for the treatment of hydrochloric acid in gastric juice is overmuch, gastric and duodenal ulcer disease, can be used as a whitening agent or sugar in food processing in delicate decoloring agent. Biggest use is used as fertilizer in agriculture and livestock feed, is a major element in the process of metabolism of plants and animals, as the cow feed, can prevent caused by magnesium deficiency neurological dysfunction. In addition can also be used for glass fiber reinforced plastic, dye and pharmaceutical industry and electronic industry, insulation materials, oil additives, casting, bakelite, etc.
