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…

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…

Since the pharmaceutical and food grade magnesium oxide project of Hebei Messi Biology Co., Ltd. has been put into production, the production and sales of magnesium oxide has reached an annual doubling growth rate. At present, the green industry chain has been formed with magnesium oxide as the source, mutual supply of products and raw materials, and finally the production of high value-added products. It is with the support of green industry chain, the company’s magnesium oxide industry to achieve benign development. In the field of fine chemicals of derivatives downstream of magnesium oxide industry chain, Messi Biology itself…

Magnesium oxide is a safe antibacterial agent, magnesium oxide antibacterial effect is related to particle size and surface morphology, magnesium oxide has no dependence on ultraviolet light compared with other materials, can avoid the toxicity of antibacterial materials due to photocatalysis, with low production cost and antibacterial conditions require simple and other significant features. Magnesium oxide also has the characteristics of non-conductivity, high temperature resistance and thermal conductivity, which is widely used in chemical, medical and food industries. The inhibition mechanism of magnesium oxide is mainly divided into oxidative damage and adsorption, magnesium oxide produces peroxide ion through redox…

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,…

As an environment-friendly inorganic chemical product, magnesium hydroxide has the advantages of high thermal decomposition temperature, better adsorption capacity and high activity, which is widely used in aerospace, environmental protection, flame retardant and other fields. Due to its physical surface properties, magnesium hydroxide is not favorable for the preparation of composite materials, so improving the physicochemical or mechanical properties of magnesium hydroxide by surface modification methods is the current direction of many scholars’ efforts. 　　1、Dry modification Dry modification refers to the modification process in the dry state of magnesium hydroxide. Hebei magnesium xi biological limited company with silane class…

Magnesium oxide to play excellent performance in different materials and applications, can not be separated from the basic research and industrial research and development in conjunction. Hebei Messi Biology Co., Ltd. pointed out that the current magnesium oxide industry is still in the low-end field, which is in urgent need of transformation and upgrading to improve the added value of products. The first thing to promote is the real combination of enterprises, research institutions and university innovation teams. Scientific research results must be truly integrated into the assembly line of enterprise operation. On the one hand, enterprises can be…

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…

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…

Light magnesium oxide reacts with water to generate magnesium hydroxide, powdered magnesium oxide reacts with sewage to generate magnesium hydroxide MgO+H2O=Mg(OH)2, magnesium hydroxide has the characteristics of buffering, large activity, strong adsorption capacity, not corrosive, safe, non-toxic and harmless, which can react out the harmful impurities such as silica in sewage, and has been widely used in water treatment system in recent years. Especially the heavy metal in the sewage is more serious to the environment because of its high toxicity, not easy to be metabolized in the environment, easy to be biologically enriched and expand along the biological…

Pharmaceutical food grade magnesium oxide is a fine magnesium salt products, only a small amount of domestic production, only a few enterprises such as Hebei Messi Biology Co., Ltd. economic benefits; most of the small size of enterprises, quality is not high, backward technology and equipment, poor market development capabilities, the industry itself is not satisfactory benefits. Reversing this passive situation, first of all, to improve the level of science and technology, increase information exchange. Improve magnesium oxide R & D and production capacity, out of the country, to participate in the global economic competition, give full play to…

ICP, XRD, particle size distribution characterization and volumetric resistivity of magnesium oxide powder were carried out by Hebei Messi Biology Co., Ltd. The results show that the insulation performance of magnesium oxide powder is not related to magnesium oxide crystalline structure, but to the particle size distribution of magnesium oxide. The narrower the particle size distribution and the smaller the particle size, the better the insulation performance of the powder. Research shows that the magnesium oxide microstructure shows that the magnesium oxide molecule has a valence band full of electrons and a very wide forbidden band, at room temperature,…
