Medical use of magnesium hydroxide

Magnesium hydroxide is widely used in PE, PP, PVC, ABS, PS, HIPS, PA, PBT, unsaturated polyester, epoxy resin, rubber, flame retardant filler of paint, chemical industry, environmental protection and other industrial fields; It is an excellent flame retardant and filler for polymer materials such as plastics and rubber. It can be used as flue gas desulfurizer in environmental protection and can replace caustic soda and lime as neutralizer for acid containing wastewater; It can be used as oil additive to prevent corrosion and desulfurization; Used for the refining of electronic industry, medicine and sugar; It is used for thermal insulation materials and other magnesium salt products.


Ordinary magnesium hydroxide: used in rubber, plastic, paint, coating, chemical industry and other industries.


Active magnesium hydroxide: active magnesium hydroxide flame retardant is widely used in rubber, chemical industry, building materials, plastics (polypropylene, polyethylene, polyvinyl chloride, ethylene propylene diene monomer), electronics, unsaturated polyester, paint, coating and other polymer materials, especially for flame retardant, smoke suppression and anti-static of coated cloth for mine air duct, PVC whole core transport belt, flame retardant rubber sheet, tarpaulin, PVC wire and cable material, mine cable sheath, cable accessories, It can replace aluminum hydroxide and has excellent flame retardant effect.


Appearance: white crystal or powder.


Packaging: The product is packed in a composite paper bag, and the inner layer is a plastic film bag, with a net weight of 25kg per bag.


Handling and storage: handle with care, seal and keep away from moisture.


Physical and chemical properties: white crystal or powder. The aqueous solution is alkaline. 2.36g/cm3。 Soluble in dilute acid and ammonium salt solution, almost insoluble in water and alcohol. The solubility in water (18 ℃) is 0.0009g/100g. Easily absorb carbon dioxide in the air. When heated to above 200 ℃ in alkaline solution, it becomes hexagonal crystal system. It is decomposed into magnesium oxide and water at 350 ℃. When the temperature is higher than 500 ℃, the water lost will be converted into magnesium oxide. Magnesium carbonate in boiling water can be converted into magnesium hydroxide with worse solubility. Particle size 1.5-2 μ m. The mesh number is 10000, and the whiteness is ≥ 95.
