      Basic requirements:                

It is generally divided into two kinds: Magnesium Oxide for pressing glue and Magnesium Oxide for direct application.

Magnesium oxide used for gluing is of large volume, good dispersibility, moderate activity and non-stick roller, and its specific volume is better at 80-120.

  Direct application of magnesium oxide requires a better activity between 120 and 150, and a better specific volume of about 5. Both kinds of magnesium oxide require calcium, and the lower the iron content, the better.

  Common quality problems:

  It is easy to produce white suspended substance if the content of magnesium oxide is too low, while the content of calcium in magnesium oxide is too high, the activity is too poor, and the fineness is not enough to easily cause precipitation and stratification.

  It is normal to produce a thin layer of white sediment at the bottom of the adhesive container. If too much is abnormal, it is a problem of magnesium oxide. It may also be a problem of talcum powder in neoprene.

  If it's too much, it's not a magnesium oxide problem. It could be a resin or solvent problem. Iron content is too high, easy to make the glue color red, iron content should not be higher than 0.05(preferably below 0.03);If it turns a little red or pink, it could be magnesium oxide or it could be neoprene; If send dark red, pig is blood-red, dark red, it is not magnesia problem, explain solvent, resin to have a problem commonly.

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.
