Magnesium Oxide application area (2)

    One of the main uses of magnesium oxide is as a flame retardant. Traditional flame retardant materials widely use halogen-containing polymer or halogen-containing flame retardant mixture. However, once a fire occurs, due to thermal decomposition and combustion, a large number of smoke and toxic corrosive gases will be generated, which hinders fire fighting and evacuation of personnel, corrodes instruments and equipment. In particular, it was found that more than 80% of the deaths in fires were caused by smoke and toxic gases produced by materials. Therefore, besides flame retardant efficiency, low smoke and low toxicity are also indispensable indicators of flame retardants. The development of China's flame retardant industry is extremely unbalanced. Chlorine-based flame retardants account for a large proportion, ranking first among all flame retardants, among which chlorinated paraffin is the monopoly. But when chlorine flame retardants act, they release toxic gases, which is far from the harmless and efficient pursuit of modern life. Therefore, in order to conform to the world flame retardant development trend of low smoke, low toxicity and no pollution, the development, production and application of magnesium oxide flame retardant is imperative.
