Mainly used in cable, rubber, medicine, adhesives, metallurgy, ceramics other industries. With the upgrading of industrialization the demand development of the high-tech functional material market, a series of high-tech fine magnesium oxide products have been developed produced, which are mainly used for lubricants, tanning alkali grade, medicine, food grade. It is composed of nearly ten varieties of silicon steel grade, electromagnetic grade, high-purity magnesium oxide. Talc manufacturer
Although magnesium oxide is an auxiliary material, its application different industries play a huge role. The role in the cable industry: play the role of vulcanization accelerator, anti-scorch agent, filler, acid absorbent, fire retardant, high temperature resistance, corrosion resistance, wear resistance; role in the adhesive industry: play The role of anti-scorching agent acid absorbent accelerates the reaction in the resin reaction liquid. It can be seen that the addition of magnesium oxide to many products is just like the need to put MSG in daily cooking, there is no taste if you put a little bit of this dish to taste delicious.
In recent years, with the development of technology, functional materials have become a research hotspot, the quality level of the raw materials of functional materials has become a yardstick for the development of functional materials. At present, it has mainly developed applications in light-emitting functional materials, optical functional materials, electronic functional materials other fields. The above functional materials have very strict requirements on the purity of raw materials.
Although there is currently no universal industry standard in the world, in addition to the application requirements of the functional material itself, the chemical reagent standard will be used as a reference standard. Taking high-purity electronic grade basic magnesium carbonate magnesium oxide as examples, they are mainly used in aerospace electronic components, military electronic components, communication equipment, radar, etc., which determine the technical indicators of high-purity electronic grade basic magnesium carbonate magnesium oxide Claim.
One of the main uses of magnesium oxide is as a flame retardant. Traditional flame-retardant materials widely use halogen-containing polymers flame-retardant mixtures composed of halogen-containing flame retardants. In the event of a fire, due to combustion thermal decomposition, a large amount of smoke toxic corrosive gases will be generated, which will corrode instruments equipment, thereby hindering fire fighting evacuation. According to statistics, more than 80% of fatalities in fires are caused by dense smoke toxic gases produced by materials. Therefore, in addition to flame retardant efficiency, low smoke low toxicity have become indispensable indicators for flame retardants.
The development of China's flame retardant industry is extremely uneven. Chlorine-based flame retardants account for a heavier proportion are the first among flame retardants. Among them, chlorinated paraffin has a monopoly position. However, chlorine-based flame retardants will release toxic gases when they act, which is far the non-toxic high efficiency pursued by modern life. Therefore, in order to comply with the development trend of flame retardants with low toxicity, low smoke no pollution, the development, production application of magnesium oxide flame retardants are imperative.
