直销 非金属粉末 批发硫化锑 硫化锑厂家

硅灰石有针状硅灰棉和硅灰粉两种，针状硅灰棉具有耐酸、耐碱化学腐蚀等。它的长径范围为18：1到20：1，具有增强作用，增强效果随长径比的增大而增加，硅灰石粉属于钙质偏硅酸盐矿物，有较好的增摩效果。硅灰棉在无石棉制品相当六级石棉增强效果，硅灰棉和少量强度好的纤维等制造具有足够的摩擦材料制品，因此得到了许多摩擦材料厂及公司广泛应用。

Wollastonite

wollastonite needle-like wollastonite wollastonite powder with cottonand two, needle-like wollastonite cotton with acid, alkali and chemicalcorrosion. Its long diameter range from 18:1 to 20:1, has enhanced the role,reinforcing effect increases with the ratio of length to diameter increases,wollastonite powder belongs to the calcareous partial silicate minerals, hasgood friction-increasing effect. Silica fume cotton in the non-asbestosproducts is six asbestos reinforced effect of silica fume, cotton and a smallamount of strength of fiber manufacturing with friction material productsenough, so had many friction material factory and the company are widely used.
