Light burned powder and magnesium oxide

[MgO] uses: used for rubber, plastics, wire, cable dyes, paint, glass, ceramics, chemical reagents, medicine, food additives, etc. 1. Metallurgical industry: used to make adhesives for refractory materials and furnace building arms, as well as raw materials for manufacturing No. 2 flux and smelting metal magnesium


2. Chemical industry: it is mainly used to make various magnesium salts, such as magnesium oxide, magnesium hydroxide and magnesium carbonate. It is also used as raw material of antifreeze


3. Building materials: hard and corrosion-resistant magnesia cement is made with magnesia bittern (MgO), which can be made into adult marble, bittern tile, floor, ceiling, decorative board, fireproof board, greenhouse support, partition board, magnesite well cover, bathtub, door and window frame, movable house, etc


4. Machinery Industry: in life, it can be used to make mechanical packing boxes, triangular cushion edges and furniture. It is a good material for "replacing materials with soil"


5. Food industry: tofu made with brine (magnesium chloride aqueous solution) is tender and delicious compared with tofu made with stone. It is an additive for some foods


6. Transportation industry: it is used as road deicing and snow melting agent, with fast deicing speed and low corrosion to vehicles, which is higher than that of sodium chloride?


7. Medicine: it is made of magnesium chloride and can be used as medicine


8. Agriculture: it can be used as magnesium fertilizer, potassium magnesium fertilizer and cotton defoliating agent. Light burning powder: MAGNESITE calcined at 750-1100 temperature is called "light burning", and its product is called light burning magnesium powder. Since the burning loss of magnesite is generally about 50%, the MgO content in the ore can be almost doubled by light burning. In this sense, light burning is the most effective means of MgO enrichment. In addition, Light burning is also a preparatory operation for magnesite thermal separation and some gravity separation. Light burning magnesium has high activity and is an ideal raw material for the production of high body density magnesia


Light burned magnesium is mainly used to make cementitious materials, such as magnesium containing cement, building materials for thermal insulation and sound insulation, and ceramic raw materials. After chemical treatment, light burned magnesium can be made into a variety of magnesium salts, which can be used as raw materials for medicine, rubber, man-made fiber, papermaking, etc. heavy burned magnesium is mostly used as refractory materials for metallurgy, It is used to make magnesia brick, chrome magnesia brick, magnesia, metallurgical powder and fused magnesia. It is mainly used as medium and high frequency induction furnace lining and magnesium crucible for smelting special alloy steel, nonferrous metals and precious metals. It can also be used as high-temperature electrical insulation material. "Their similarity is fire resistance."
