经过拣选、破碎、磨细到325-1250目**成为白云石粉，在摩擦材料中，其作用与轻钙粉性能基本相同。经表面改性剂改变白云石粉表面碱性，提高其与橡胶摩擦材料制品的结合性能从而大大增加其补强性能。由于其开采容易，成本低廉，在作为摩擦材料的填料当中被广泛采用。
Dolomite powder
Dolomite powder is sorted, crushed, grindedto 325-1250 Mesh , in the friction material, its role is basically the samewith the light calcium powder performance. after surface modification agent tochange the white surface alkaline powder, improve and rubber friction withproperties of materials so as to greatly increase the reinforcing properties.Because of its mining easy, low cost, is widely used in friction as filler.
