Usage: Magnesium hydroxide is widely used in PE, PP, PVC, ABS, PS, HIPS, PA, PBT, unsaturated polyester, epoxy resin, rubber, flame retardant filler for paint, chemical industry, environmental protection and other industrial fields; Excellent flame retardant and filler for polymer materials such as plastics and rubber, used as flue gas desulfurizer in environmental protection, can replace caustic soda and lime as neutralizer for acid-containing wastewater; It can be used as oil additive to prevent corrosion and desulfurize; Used for refining of electronic industry, medicine and granulated sugar; It is used for thermal insulation materials and other magnesium salt products.
Ordinary magnesium hydroxide: used in rubber, plastic, paint, paint, chemical and other industries.
Active magnesium hydroxide: active magnesium hydroxide flame retardant, widely used in rubber, chemical industry, building materials, plastics (polypropylene, polyethylene, polyvinyl chloride, EPDM) and electronic, unsaturated polyester, paint, coating and other polymer materials, especially for the flame retardant, smoke suppression and anti-static of mining air duct coating cloth, PVC whole-core conveyor belt, flame retardant rubber plate, tarpaulin, PVC wire and cable material, mining 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 composite paper bags, and the inner layer is made of plastic film bags, with a net weight of 25kg.
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. It is easy to 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 lost water is 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. Mesh count 10000, whiteness ≥ 95.
