Applications of Magnesium Oxide

There are many different applications of magnesium oxide. Refractories Magnesium include has always been a source for making refractory brick in the steel industry. The ceramic material is typically impregnated with carbon materials, such as tar, pitch, or graphite to enhance the properties of the finished material, especially against corrosion in environments of basic slags. Magnesia bricks are widely used in combination with spinel or chrome in ferroalloy, non-ferrous, glass and cement manufacturing industries. Crucibles Magnesia crucibles are used in the superalloy, nuclear industry, and chemicals industries to mitigate the corrosion of the substance. Magnesium crumbles often come in different purity…

Application of nano magnesium oxide in textile and mask

The PM2.5 masks commonly used in the market can only filter particles with a diameter of 2.5μm in the air, while N95 masks can block 95% of particles with a diameter of 2.5μm in the air. viruses such as influenza, Ebola and mers can be suspended in the air with a diameter generally between 60-140nm and a minimum diameter of up to 70-90nm. by comparison it can be seen that PM2.5 mask cannot resist the attack of the virus. If a new type of protective equipment can resist the invasion of nano virus, the infection rate of human will…

Compression resistance properties and effect of magnesium oxide in rubber

Magnesium oxide is a common chemical, its use is very wide, in the rubber products magnesium oxide can improve the dispersion, with the amount of magnesium oxide increases, the storage energy modulus difference is decreasing trend. The dispersion of filler in rubber is best when the amount of magnesium oxide is a certain proportion. The effect of the amount of magnesium oxide on the loss modulus of the kneading rubber, with the increase of the amount of magnesium oxide, in order to reduce, indicating that magnesium oxide can destroy the filler in the rubber formed by the aggregation network,…

A preparation method of surface-modified magnesium oxide nanomaterials dedicated to SMC thickening

SMC material is composed of SMC special yarn, unsaturated resin, low shrinkage additives, thickeners and other fillers. It has a wide range of applications in the transportation vehicle, construction, and electronic/electrical industries because of its superior electrical properties, corrosion resistance, and high flexibility. During the preparation of SMC, thickening agents have a great influence on the properties of SMC materials. For chemical thickening of unsaturated polyesters, the most used are alkali metal oxides or hydroxides, such as magnesium oxide, calcium oxide, or barium oxide and corresponding hydroxides. But the relevant industry experience and research results show that: calcium-related materials…

Magnesium oxide can improve the heat resistance and anti-aging property of rubber

The heat resistance of rubber is closely related to its molecular structure and rubber components, temperature, mechanical action and surrounding environmental media. Usually the chemical stability of rubber is also a key factor affecting the heat resistance performance. General conventional light-colored filler heat resistance aging performance is better than reinforcing filler carbon black, can choose white easy powder of magnesium oxide and white carbon black and improve the heat resistance of nitrile rubber material. Use magnesium oxide as acid absorbing agent or vulcanizing agent, it can produce adiabatic effect which can improve the heat resistance of rubber material, and…
