At present, the most important use of magnesium oxide by magnesium oxide manufacturers is magnesium oxide as a flame retardant. As a traditional flame retardant material, flame retardant mixtures composed of halogen-containing polymers or halogen-containing flame retardants are generally selected. However, once a fire occurs, due to thermal decomposition and incineration, there will be a lot of smoke and toxic corrosive gases, which will hinder the lax fire fighting and personnel and corrode instruments and equipment. 96 fused magnesia

In particular, more than 80% of deaths in fires are caused by smoke and toxic gases. Therefore, in addition to flame retardant ability, low smoke and low toxicity is also an indispensable principle of flame retardants. China's flame retardant industry market is not very stable, chlorine-based flame retardants account for a large proportion of all flame retardants, of which chlorinated paraffin dominates. However, chlorine flame retardants release toxic gases when they react, which is far from the toxic efficiency that is pursued in today's life. Therefore, in order to adapt to the development trend of low smoke, low toxicity and no pollution of flame retardants in the world, it is imperative to develop, produce and use magnesium oxide flame retardants.

For the determination of sulfur and arsenic in coal, pyrite and steel. White pigment specification. Light magnesia is widely used in various fields. It can also be used as chloroprene rubber, fluorine rubber polish, binder, coating, papermaking filler, catalyst and activator. After mixing with magnesium chloride, magnesium oxide is prepared for water transfer. It is used in medicine as an antacid and laxative to treat excess stomach acid and duodenal ulcers. Used in the chemical industry as a catalyst and material for magnesium salt production. It can also be used in glass, dyeing powder, phenolic plastic and so on. Magnesium oxide heavy magnesium oxide is used for milling and semi-milling in the rice milling industry. The construction industry mainly uses artificial chemical floor, artificial marble insulation board, soundproof board and plastic industry as filling materials. It can also be used to produce other magnesium salts.

It has a strong refractive index in the visible and near ultraviolet light programs. Magnesite (MgCO3), dolomite (MgCO3) and seawater are the main data for the production of magnesia. Magnesia manufacturers of magnesium oxide is obtained by the thermal decomposition of magnesite or dolomite. Magnesium hydroxide is accumulated by treating seawater with lime, and magnesium hydroxide is obtained by burning magnesium hydroxide. This is still the most basic information that can be extracted using seawater. At the same time, it can also produce a certain amount of magnesium oxide, or form a deposit of basic magnesium carbonate, and then burn to obtain magnesium oxide.
