Active Magnesium oxide is one of the important raw materials of neoprene adhesive. The activity of magnesium oxide reflects the reaction ability between magnesium oxide and neoprene adhesive. The activity of active Magnesium oxide is usually absorbed by iodine (mgT2lg). When the iodine absorption value is lower than 40, the activity is lower (mgIz/g). Intermediate activity is between 40-100 of iodine absorption value. It is highly active when the iodine absorption value is higher than I0. In general, high quality neoprene requires highly active iron oxide. Poly-neoprene is an important type of fluorine rubber adhesive, with large production capacity and wide use. It has the advantages of high initial adhesion, high bonding strength, flexible bonding layer and good elasticity. More importantly, it has anti-impact, water resistance, oil resistance, alkaline resistance, acid resistance and solvent resistance. Of course, it has a good reaction. It is resistant to ozone, aging, durability and fire resistance. Therefore, it can put many metal materials and non- Metal material. For example, it can be used to glue rubber, leather, fabric, artificial leather, wood, beton, asbestos, etc. It is especially suitable for the bonding between the above materials and different materials such as metal and plastic. Also, it has three types. Solvent-based, liquid-based and non-solvent type. Among them, the solvent-based neoprene adhesive is the most widely used. The solvent type of neoprene adhesive can be divided into hot curing type and cold bonding type. At present, the most extensive The used neoprene is a solvent-based and cold-adhesive. Meishen technology is a professional magnesium oxide manufacturer that can produce all kinds of magnesium oxide. The specialty magnesium oxide used in the adhesive is one of the company\'s brand magnesium sands. Its market share is over 90%. In Shandong, Hebei, Shanghai, Jiangsu and other industries, the market share of the rubber cable industry has always been more than 80%. The company is a well-known brand in the magnesium salt industry, leading the light magnesium oxygen and active magnesium oxygen market used in the domestic adhesive industry from 1995 to 2006.
