High Purity Magnesium Hydroxide

High Purity Magnesium Hydroxide, the chemical formula is Mg(OH), white solid, crystalline or amorphous powder, insoluble in water, alkaline solution, dilute acid and ammonium salt solution, decomposed to magnesium oxide and water by heating, the initial decomposition temperature is 340oC, the decomposition is completed at 490 oC. Adopting the advanced technology, processed by reaction synthesis, filtering, washing, drying processes, the content more than 99%, average particle size is 50μm, bulk density is 1.29g/cm3, also supply on request, it can be processed to 1～50μm, the bulk density reach 0.3～1.29 g/cm3. The product if safe and non-toxic, non-hazardous to the environment, does not belong to the flammable, explosive product. The quality is better than other similar product. The product uses the bischofite (MgCI·HO2) of Qinghai Salt Lake as raw material, adopting synthetic production, all products reach the high purity level, as the end product can be used directly in the flame retardant (iron and steel, non-ferrous, chemical, plastics, rubber), electronics, medicine, food and other industries, where the greatest demand is flame retardant industry, it is also used as the good raw material of the production of light purity magnesium oxide, high purity heavy magnesium oxide, pharmaceutical grade magnesium oxide, food-grade magnesium oxide, electrical oxide magnesium, silicon steel grade magnesium oxide and other high-end magnesia products. The product as an excellent flame retardants and filler can be widely used in EVA, PP, PVC, PS, HIPS, and ABS plastic, can also be used in unsaturated polyester, paints and coatings. In environmental engineering as a pollution-free neutralizer, filler in the paper industry, gas purification and boiler exhaust gas and waste oil desulfurizer, also for magnesium manufacturing, sugar refining, pharmaceutical, tooth powder, insulation materials, wire and cable, conveyor belt, the wind guide Jane, electrical equipment, new building materials, glass fiber reinforced plastic products, paints, and as a soil conditioner and so on, is an environment-friendly functional material.   Test Sheet   Product: Magnesium Hydroxide                           Date: 24 March 18 指标项目 Items 氢氧化镁原粉 Unmilled MH 氢氧化镁细粉(Milled MH) 氧化镁 CCM XMH-15 XMH-55 SCH-13 SCH-13.1 SCH-13.2 氢氧化镁(Mg(OH)2) Magnesium hydroxide ≥99.00% ≥97.5% 氧化钙（CaO） Calcium oxide ≤0.05% ≤0.05% // 盐酸不溶物 Insoluble matter in HCl ≤0.10% // 水分 Moisture ≤0.50% // 总氯化物(以Cl-计) Total chloride(in Cl-) ≤0.50% ≤0.50% 0.51%-0.6% ≥0.61% ≤0.4% 铁（Fe2O3） Iron oxide  ≤0.01%   灼烧失量 LOI ≥30% ≤3.0% 白度 Whiteness  ≥97.0%   激光粒度（D50）/μm Laser Particle size(D50) 40-60 1-2 5-6 1-3   激光粒度(D100)/μm Laser Particle size(D100) // 15 //   //   325目通过率 Passing rate on 325mesh // // ≥99%   //   堆积密度(g/cm3) Bulk density ≥0.90 // ≥0.70
