Light burnt magnesia powder after scientific and technological innovation
Light burned magnesia is a folding, pressure resistant, high strength, gel material. It is widely used in rubber, plastics, wires, cables, dyestuffs, paints, glass, ceramics, chemical reagents, pharmaceuticals, food additives, etc. with the continuous progress and development of science, Magnesium Oxide has made wider use in industry.
Magnesium oxide, Magnesia usta, Calcined magnesia, Magcal, Maglit. Magnesium powder, white powder, odorless, tasteless, it is insoluble in water or ethanol, slightly soluble in ethylene glycol, melting point 2. 852 C, boiling point 3600 C, light burnt magnesia powder has high fire resistance and insulation performance. It can be transformed into crystals by high temperature burning above 1000 C, and sintered magnesia or magnesia by dead burning up to 1500 C. Light burnt magnesia powder is an alkaline oxide, which has the properties of alkaline oxide and belongs to cementitious material. When exposed to air, it is easy to absorb water and carbon dioxide and gradually become basic magnesium carbonate. It combines with water to form magnesium hydroxide, which is slightly alkaline. The pH of saturated water solution is 10.3. Soluble in acid and ammonium salt, insoluble in water, its solution is alkaline. It is insoluble in ethanol.
Physicochemical indices of light burnt magnesia powder:
Light burnt magnesia powder, good color, high purity, magnesium content as high as 85%, processing from 120 mesh to 325 mesh. The light-burnt magnesia powder produced far exceeds the domestic industry standards. On the basis of smooth, bright and beautiful, it has more advantages of pressure and wear resistance, high temperature resistance, corrosion resistance, fire retardant and flame retardant. It is the ideal raw material for replacing green products in thermal insulation buildings which are now the focus of promotion in China.
