氢氧化镁应用领域 Applications of Magnesium Hydroxide

1. Magnesium hydroxide is an excellent flame retardant for plastic and rubber products. As flue gas desulfurizer in environmental protection, it can replace caustic soda and lime as neutralizer of acid-containing wastewater. It can also be used as an oil additive to prevent corrosion and desulfurize. In addition, it can also be used in the electronics industry, medicine, sugar refining, thermal insulation materials and other magnesium salt products.


2. Magnesium hydroxide has excellent cushioning performance, reaction activity, adsorptive force and thermal decomposition performance. It can be used not only as chemical materials and intermediates, but also as a green flame retardant and additive for rubber, plastics, fibers and resins. Magnesium hydroxide is mainly used as flame retardant, acid wastewater treatment agent, heavy metal removal agent and flue gas desulfurization agent in the field of environmental protection.


3. The product can be used as flame retardant or flame retardant filler to add to polyethylene, polypropylene, polystyrene and ABS resin. It has good flame retardant and smoke suppression effect, and the amount of addition is 40-20 phr. Anionic surfactants such as alkali metal salts, alkyl sulfates and sulfonated succinates can be used to treat the surface of particles, and the dosage is about 3%. The product is also used in the manufacture of magnesium salts, refinement of granulated sugar, pharmaceutical industry, daily chemical industry and so on.


4. Magnesium hydroxide is a new type of filled flame retardant, which releases bound water and absorbs a large amount of latent heat during thermal decomposition to reduce the surface temperature of the composite filled with it in the flame. It has the function of inhibiting polymer decomposition and cooling the flammable gas produced. Magnesium oxide produced by decomposition is also a good refractory, and it can also help improve the fire resistance of synthetic materials. At the same time, the water vapor it emits can also be used as a smoke suppressant. Magnesium hydroxide is recognized as an excellent flame retardant with three functions of flame retardant, smoke suppression and filling in the rubber and plastic industry. It is widely used in rubber, chemical industry, building materials, plastics and electronics, unsaturated polyester, paint, paint and other polymer materials. Especially, it can replace aluminium hydroxide with flame retardant effect for coating of mine air duct, PVC Whole-core conveyor belt, flame retardant aluminium plastic plate, flame retardant tarpaulin, PVC wire and cable material, mine cable sheath, cable accessories, flame retardant, smoke suppression and antistatic. Compared with similar inorganic flame retardants, magnesium hydroxide has better smoke suppression effect. Magnesium hydroxide does not emit harmful substances in the process of production, use and waste, and can neutralize acid and corrosive gases produced during combustion. When used alone, the dosage is generally 40%-60%. It has good compatibility with base resin and is an excellent flame retardant for thermoplastic resins and rubber products. Adhesives are often used as additive flame retardants or flame retardant fillers with reference dosage of 40-200 phr. It is used in manufacturing magnesium salts, active magnesium oxide, pharmaceuticals, fine ceramics, thermal insulation materials, sugar refining, flue gas desulfurizer, oil anti-corrosion additives, acid-containing wastewater neutralizer, color TV picture tube cone glass coating and so on.


5. The product is also used in the manufacture of magnesium salts, refinement of granulated sugar, pharmaceutical industry, daily chemical industry and so on. At the same time, the water vapor it emits can also be used as a smoke suppressant. Magnesium hydroxide is an excellent flame retardant with three functions of flame retardant, smoke suppression and filling in the rubber and plastic industry.


6. Magnesium hydroxide emulsion suspension is used as an acid-making agent and a laxative in medicine.
