Product description, Product introduction:
Barite powder is grey ink or white powder, it is
made bybarite ore,the main composition is BaS04.
physical properties of barite: Mohs Scale Hardness is from 2.5 to 4.5,density is from 4.3 g/cm3 to 4.5 g/cm3,and the melting point is 1580 degree centigrade .
whenBarite is used in friction materials ,it can improve performance and reduce the cost,it is suitable for disc brake pads,drum brake pads and clutch
etc..
The recommended regular consumption of barite is from 2% to 8%.
The character of Feldspar:
Barite is the most widely used friction material, it can keep stable friction coefficient and small particles.
Barite especially can form a stable boundary friction layer at high temperatures to prevent the dual material surface scratch and to make the dual surface grinding more bright and clean.
Used in the friction material,with dispersity barite is easy to adsorption with all kinds of resin, so as to improve high temperature resistant andwear resistance of the adhesive.
With unique physical and chemical properties,Barite is widely used in all industries,especially in the oil industry,chemical industry,friction industry and abrasive industry etc.
