    Xiaobian for everyone to explain the role of light burn powder and magnesium oxide

    Date:2019-10-08 Author: Click:

    "Light burnt powder" is a product that is lightly burned at about 900 ° C with natural magnesite or brucite. Commonly known as light burnt powder. The main chemical component is magnesium oxide. Magnesium oxide expressed in the general sense refers to magnesium oxide produced by chemical methods. It is a magnesium oxide obtained by calcination using magnesium-containing raw materials, magnesium carbonate or magnesium hydroxide produced by a chemical method. Therefore, the so-called magnesium oxide, generally, the purity, particle size, live *** and other indicators and light burning powder are significantly different. Fused magnesium


    Uses: Used in rubber, plastics, wire, cable dyes, paints, glass, ceramics, chemical reagents, medicines, food additives, etc. 1. Metallurgy industry: used to make refractory materials and furnace arm adhesives, and is manufactured No. 2 flux and raw material for smelting magnesium metal.


    2. Chemical industry: mainly used to make various magnesium salts, such as magnesium oxide, magnesium hydroxide, magnesium carbonate, and also used as raw materials for antifreeze.


    3. Building materials: Made of hard and corrosion-resistant magnesia cement with diamond bituminous earth (MgO), can be used to make marble, bitter tile, floor, ceiling, decorative board, fireproof board, greenhouse bracket, partition board, magnesite Manhole covers, bathtubs, door and window frames, and mobile homes.

    4. Machinery industry: In life, the use of diamond bitter soil can be made into mechanical packaging boxes, triangular cushions and furniture, etc., which is a good material for “materials by earth”.


    5. Food industry: Tofu made from brine (magnesium chloride aqueous solution) is more toasted than stone, which is tender and fresh, and is a food additive.


    6. Transportation industry: used as a road ice melting agent, the ice speed is fast, the corrosion to the vehicle is small, and it is higher than the sodium chloride effect. ?


    7. Medicine: It is medicinal to make "halogen dry" with magnesium chloride.


    8. Agriculture: It can be used as magnesium fertilizer, potassium magnesium fertilizer and cotton defoliant. Light-burning powder: Magnesite is calcined at a temperature of 750-1100, which is called "light burn". Its product is called light burned magnesium powder. Since the reduction of magnesite is generally about 50%, the content of MgO in ore is lightly burned. It can be almost doubled. In this sense, light burning is an effective means of enriching MgO. In addition, light burning is also a preparatory operation for hot selection of magnesite and some re-election. Light burnt magnesium has high activity. It is an ideal raw material for the production of high-density magnesia.


    Light burnt magnesium mainly manufactures cementitious materials, such as magnesium-containing cement, building materials that are insulated and sound-insulating, and can also be used as ceramic raw materials. After chemical treatment of light burnt magnesium, a variety of magnesium salts can be made for use as medicine.
