Magnesium hydroxide is a colorless hexagonal crystal or white powder, insoluble in water and alcohol, soluble in dilute acid and ammonium salt solution, the aqueous solution was weakly alkaline.
Magnesium hydroxide is recognized as an excellent flame retardant with three functions of flame retardancy, smoke suppression and filling in the rubber and plastic industry. It’s widely used in rubber, chemicals, building materials, plastics and electronics, unsaturated polyester and paint, coatings and other polymer materials. Especially for the mine air duct coating cloth, PVC whole core transport belt, flame retardant aluminum panels, flame retardant tarpaulin, PVC wire and cable materials, mining cable sheath, cable accessories flame retardant, smoke and antistatic , Can replace aluminum hydroxide, with excellent flame retardant effect. Compared with similar inorganic flame retardants, magnesium hydroxide has a better smoke suppressing effect. Magnesium hydroxide in the production, use and disposal of non-hazardous substances in emissions, but also to neutralize the combustion process of acid and corrosive gases. When used alone, the amount is generally 40% to 60%.
For Magnesium Hydroxide Ultrafine grinding mill, Guilin hengda is a good choice. HGM ultrafine grinding mill is a new type grinding equipment with optimum structure design for the ultrafine powder industry. It has the following advantages.
1.PatentedTechnology structural innovation
Grinding the use of multiple layers of multiple grinding roller, grinding wheel bracket with a combination of structure, the drive spindle is a multi-angle diamond-shaped structure, crushing power strong,less maintenance, easy demolition, low cost, and the finished product does not turn
2. High energy efficiency
Feed size <10mm of the lump, a one-time processing of 5 ~ 75Ојm micron powder, high content of fine powder, the product of large surface area.
3. Stable performance with good fineness
HGM multi-layer curved roller mill is the ideal equipment for the current dry production of non-metallic mineral powder. Main Unit equipped with built-grading institutions, grading wheel unique structure, grading effect, powder particles concentrated, no large particles of pollution.
4.Material resistance, good shock absorption
Grinding ring with a special wear-resistant alloy steel or high chromium manufacturing, life increased by 2 to 3 times. Main unit base with the overall cast steel structure, high structural strength, shock absorption performance.
