Product description, Product introduction: Dolomite is White powder, the main ingredient is calcium carbonate and magnesium carbonate.The physical properties of dolomite is that Moh�??s Scale Hardness is from 4.5 to 4.0,density is from 2.8 g/cm3 to 2.9 g/cm3. Dolomite is decomposed into carbon dioxide calcium oxide and magnesium oxide when tempreture is between 700 and 900 degree centigrade. Dolomite is made by crushed Dolomite ore.It is used as friction material to for stable friction coefficient,and can improve process performance, improve the wear resistance of friction material, and reduce the cost.Dolomite used in Brake pad Drum brake or clutch.The recommended regular consumption of Diatomite is unlimited.. The character of Dolomite: Dolomite, also known as bitter ash stone, it is the double salts of calcium carbonate (CaCO3) and magnesium carbonate (MgCO3), The theoretical ratio is: MgC03 accounted for 45.65%, and MgCO3 accounted for 4.35%. Appearance of dolomite is yellow white, Pink.The kind is of shiny crystalline white clouds and crystalline dolomite two absorption. Dolomite has good fireproof , heat insulation and waterproof performance Dolomite can be used as friction material to reduce the cost.with application in the brake pads, the function is to improve the stability of the friction coefficient. Property: A1203: 0.04% SiO2: 1.10% Fe203: 0.23% CaO: 33.96% MgO: 22% min grade:200mesh,325mesh sieving rate: 97%
