Adhesive is magnesium oxide in the use of large, normal adhesive enterprises, basically every month the consumption of magnesium oxide in about 2 tons, which can fully explain magnesium oxide is the indispensable production raw materials in the adhesive, we will understand in detail below the adhesive special magnesium oxide effect how?

Active magnesium oxide is one of the important raw materials of chloroprene adhesive. The activity of magnesium oxide reflects the reaction ability of magnesium oxide and chloroprene adhesive. The higher the activity, the faster the reaction rate with neoprene. Active magnesium oxide has many functions in chloroprene adhesive, such as curing crosslinking, acid absorption, anti-coke burning and chelating with resin.

Due to its large specific surface area and high activity, active magnesium oxide can be used in chloroprene adhesive to improve its initial adhesion and bonding strength. Improve the transparency of adhesive. The biggest characteristic can prevent the lamination precipitation of adhesive.

The activity of active magnesium oxide is generally expressed by the iodine absorption value (mgI2/g). The iodine absorption value less than 40(mgI2/g) is low activity, the iodine absorption value between 40 and 100 is medium activity, and the iodine absorption value greater than 100 is high activity.

High - quality chloroprene adhesive is usually made of highly active magnesium oxide. The reaction of active magnesium oxide with tert-butyl phenolic resin during the chelate reaction requires high activity of active magnesium oxide (iodine absorption value is higher than lOOmgI2/g), large specific surface area, fine particles, good dispersion, and moderate accumulation density (.29/cm3~0.3g/cm3).

High accumulation density, easy to precipitate; Low accumulation density and harsh operating environment. In addition, active magnesium oxide moisture absorption should be prevented.

Because water is adsorbed on the surface of active magnesium oxide, part of the inner and outer surfaces are wetted, which weakens the activity of active magnesium oxide and affects the chelation reaction.

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.
