氢氧化镁(阻燃剂)

Environment-friendly products,excellent flame retardent for plastic and rubber ariticles. For super small particle ,it can mainly be used as additive for oil products with corrosion resistence and desulfurization functions . For its high purity and small particle size ,it is used in medicine as magnesium source and purgative ,etc and as anti-acid agent in toothpaste cosmetics . Mg(OH)2 Content% 98.0%min SiO2(%) 1.0max CaO(%) 3.0max Fe2O3(%) 0.3max Sulphate(SO4) 0.5%max Attached water(%) 0.8%max Loss on ignition(%) 29.0-31.0 Insoluble in HCI Solution( %) 0.1max PH vaule 9.0-11.0 Whiteness (%) Min95.0 Mean particle diameter 15.0max Because ite demoposition temperature is lower magnetite ,the soft burned magnesium hydroxide will have a high acticity,and may be used to prodeuce magnesium oxide with higy activity. Besides ,As Mg-based compound resource ,it is also widely used for the production of magnesium salt such as magnesia as well as downstream products ,such as magnesium acetate ,magneisum carbonate. In environmental protection field ,it can replace caustic soda and lime as neutralizing agent for acid containing wastewater It may also be used to smelt magnesium metal and as a material in heat perserving products or compounds Heavy grade of Magnesium Hydroxide may also be applied to pottery industry
