Mainly used in cables, rubber, medicine, adhesives, metallurgy, ceramics and other industries.
With the industrialization upgrade and the demand and development of the high-tech functional material market, a series of high-tech fine magnesium oxide products have been developed and produced, which are mainly used in advanced lubricating oil, advanced tanning and alkali extraction, pharmaceutical and food grades. It is composed of nearly ten varieties such as silicon steel grade, advanced electromagnetic grade, and high-purity magnesium oxide.
Although magnesium oxide is an auxiliary material, its application and role in different industries are very huge.
Role in the cable industry: role as vulcanization accelerator, anti-scorch agent, filler, acid absorber, fire retardant, high temperature resistance, corrosion resistance, wear resistance; role in the adhesive industry: role as vulcanization accelerator, The role of anti-scorch agent and acid absorbing agent accelerates the reaction in the resin reaction liquid. It can be seen that many products are added with magnesium oxide, just like in daily cooking, it is necessary to put MSG in it.
In recent years, with the development of technology, functional materials have become a research hotspot, and the quality level of raw materials of functional materials has become a measure of the development of functional materials. At present, it has mainly developed applications in luminescent functional materials, optical functional materials, electronic functional materials and other fields. The above functional materials have very strict requirements on the purity of raw materials.
Although there is no general industry standard in the world, in addition to the application requirements of the functional materials themselves, the standard of chemical reagents will also be used as the reference standard. Taking high-purity electronic grade basic magnesium carbonate and magnesium oxide as an example, they are mainly used in aerospace electronic components, military electronic components, communication equipment, radar, etc., thus determining the technical indicators of high-purity electronic grade basic magnesium carbonate and magnesium oxide. Require.
One of the main uses of magnesium oxide is as a flame retardant.
Traditional flame retardant materials widely use halogen-containing polymers or flame-retardant mixtures composed of halogen-containing flame retardants. Once a fire occurs, a large amount of smoke and toxic corrosive gases will be generated due to combustion and thermal decomposition, which will corrode instruments and equipment, thereby hindering fire fighting and evacuation. According to statistics, more than 80% of the fatalities in fires are caused by the thick smoke and toxic gases produced by materials. Therefore, in addition to the flame retardant efficiency, low smoke and low toxicity have become indispensable indicators of flame retardants.
In line with the development trend of low toxicity, low smoke and pollution-free flame retardants in the world, the development, production and application of magnesium oxide flame retardants are imperative.
The development of China's flame retardant industry is extremely unbalanced. However, chlorine-based flame retardants will release toxic gases when they act, which is far from the non-toxic and efficient pursuit of modern life.
