Light burned magnesium powder It is the product of light burning of natural magnesite or brucite at about 900 ℃. It is commonly known as light calcined powder. The main chemical composition of calcined powder is magnesium oxide. Generally speaking, magnesium oxide refers to magnesium oxide produced by chemical method. It is the magnesium oxide obtained by calcining the magnesium carbonate or magnesium hydroxide produced by chemical method using magnesium containing raw materials. Therefore, the so-called magnesium oxide generally has obvious differences in purity, particle size, and other indicators from the light calcined powder.
Uses: Used in rubber, plastic, wire, cable dye, paint, glass, ceramics, chemical reagent, medicine, food additive, etc 1. Metallurgy industry: It is used to manufacture refractory materials and adhesives for building furnace arms, and is the raw material for manufacturing No. 2 flux and smelting magnesium metal.
2. Chemical industry: It is mainly used to produce various magnesium salts, such as magnesium oxide, magnesium hydroxide, magnesium carbonate, and also used as the raw material of antifreeze.
3. Building materials: hard corrosion-resistant magnesia cement made with magnesite clay (MgO) can be used to manufacture marble, terrazzo tile, floor, ceiling, decorative board, fireproof board, greenhouse support, partition board, magnesite manhole cover, bathtub, door and window frames, mobile houses, etc.
4. Machinery industry: In our daily life, we can make machinery packing boxes, triangular ribs and furniture with bitter clay, which is a good material for "replacing materials with soil".
5. Food industry: Tofu made with brine (magnesium chloride aqueous solution) is more tender and delicious than that made with stone. It is an additive for some foods.
6. Transportation industry: It is used as road deicing and snow melting agent. It has fast deicing speed, low corrosiveness to vehicles, and is more effective than sodium chloride?
7. Medicine: "dried halogen" made of magnesium chloride can be used as medicine.
8. Agriculture: It can be used as magnesium fertilizer, potassium magnesium fertilizer and cotton defoliant. Light calcined powder: Magnesite calcined at 750-1100 is called "light calcined", and its product is called light calcined magnesium powder. Since the reduction of magnesite calcination is generally about 50%, the content of MgO in ore can almost be doubled by light calcination. In this sense, light calcination is an effective means of MgO enrichment. In addition, light calcination is also a preparatory operation for magnesite thermal separation and some gravity separation. Light calcined magnesium has high activity, It is an ideal raw material for producing high density magnesia
Light burned magnesium is mainly used to manufacture cementitious materials, such as magnesium cement, building materials for heat insulation and sound insulation, and also can be used as ceramic raw materials. After chemical treatment, light burned magnesium can be made into various magnesium salts for medicine
