Some indexes of active magnesium oxide are different from those of ordinary magnesium oxide.

For example, active magnesium oxide should have a suitable particle size distribution, and its microscopic morphology should be irregular particles or near-spherical particles and flaky crystals. Because of its high dispersibility and high activity, it can even be made into fibrous magnesium oxide, which is easy to be combined with polymers and other materials.

Because the ultramicron magnesium oxide has the high dispersibility, also may use as the paint, the cosmetics, the paper filler, as well as the rubber and the plastic reinforcement and the filler, each kind of electronic material auxiliary material and so on. The activity of magnesium oxide mainly depends on two factors: one is the crystallization of magnesium oxide. The more complete the crystallization, the fewer defects, the more stable and the lower the activity.

Moreover, high calcination temperature is conducive to the crystallization of magnesium oxide. The higher the calcination temperature, the more complete the crystallization of magnesium oxide and the lower the activity. The second is the particle size of magnesium oxide. The smaller the particle size is, the greater the surface free energy is and the higher the activity is.

In China, industrial magnesium oxide is roughly divided into active magnesium oxide and light magnesium oxide. In industry, the active magnesium oxide is mainly used in fiberglass, fluororubber, medical rubber plug, adhesive and other industries.

Active magnesium oxide can be used in the adhesive industry, mainly used in neoprene adhesives, common rubber, all-purpose glue, A90 neoprene glue, etc., mostly appear in the shoe material market and decorative material market. Among them, the activity value of magnesium oxide for FRP is =60-120, that for fluororubber is =120-150, that for medical rubber plug is =150, and that for adhesive is =150.

At the same time, Magnesium God company can also according to different manufacturers, different formula, different process for professional customization, the proportion of suitable special magnesium oxide. Ultrafine high active magnesium oxide is a new type of high functional fine inorganic material.

In general, ultrafine powders refer to aggregates of nanoparticles with particle sizes ranging from 1 to 2000nm. Because the particles are fine, it has the special properties of light, electricity, heat, chemistry and mechanics, which are different from the bulk materials.

Ultrafine magnesium oxide can be combined with polymers or other materials and has good microwave absorption performance. The ultrafine powder magnesium oxide can be sintered at low temperature without the use of sintering assistant, and the high density fine crystal ceramics can be made. Therefore, the ultrafine magnesium oxide powder is expected to be developed into a cutting-edge material that can be used in the harsh conditions of high corrosion and high temperature.

Secondly, ultrafine magnesium oxide powder can also be used as a stabilizer and sintering assistant for other nanoparticles such as iron oxide, alumina and zirconia, so as to make high quality nanometer phase ceramics.

At the same time, it can also be used as an auxiliary material for various electronic materials. In addition, generally, magnesium oxide with iodine absorption value higher than 120mg/g is classified as highly active magnesium oxide, which is mainly used as activator and promoter for fluororubber, butyl rubber, neoprene rubber, nitrile rubber, and also as filler for adhesives, paints, plastics and paper. Ultra-fine and highly active magnesium oxide has high surface chemical activity and strong adsorbability, so it can be used as a highly effective dissociation adsorbent to adsorb toxic chemicals.

Meishen is the world's leading producer of magnesium oxide, Magnesium oxide is an oxide of magnesium, an ionic compound. It is a white solid at room temperature. Magnesium oxide exists in the form of periclase in nature and is a raw material for magnesium smelting. Magnesium oxide is white or light yellow powder, odorless, tasteless, this product is insoluble in water and ethanol, melting point 2852 ° C, boiling point 3600 ° C, magnesium oxide has high refractory insulation properties. It can be converted into crystal by burning at a temperature above 1000 ° C. If it rises above 1500 ° C, it will form a burnt magnesia or sintered magnesia.

Magnesium oxide can be used in the manufacture of metallurgy, smelting, advanced magnesia bricks, refractory materials and moisturizing materials. It is also widely used in rubber, rubber sheet, rubber products, pharmaceutical industry, food industry, plastic sheet accelerator, glass fiber reinforced plastics and Surface coating of silicon steel sheet, paper production, steel ball polishing, leather treatment, insulation materials, grease, dyes, ceramics, desiccant, resin, flame retardant, etc.

Hebei Meishen Chemical Technology Group is the main magnesium oxide producer in the world. It is also the largest magnesium salt producer in China and has won the ISO9002 quality system certification. It also has GMP-Certification.

With rich experience in the research, development, production, management and operation of magnesium oxide products, Meishen Group has always attached great importance to the research and development of new products and strict requirements on product quality. Meishen has a high-level sales team. The business covers more than 20 countries and regions around the world. It is widely welcomed by new and old customers.
