氟化物 KM-F004冰晶石 冰晶石厂家 冰晶石批发 无机盐

属单斜晶系，呈灰白色或灰黄色，其主要成分是氟化钠，它和工业氟化钠都被作为良好的增摩填料，用于摩擦材料中，与树脂相容性很好，具有包覆、减磨作用，能在摩擦界面形成一层薄膜，因而可以降低磨损，避免产生噪音。它和萤石（氟化钙）想比较，具有较低的磨损率，而价格高。冰晶石和萤石在摩擦材料中，是系数硬度不高，但具有增摩效果的填料品种之一。

Cryolite

Monoclinic, grayish white or pale yellow, its mainingredient is sodium fluoride, sodium fluoride and industry are as good asfiller for increasing friction, friction materials, compatibility with resinwell, with a coating, reduce wear, can form a layer of film on the frictionsurface, which can reduce the wear, avoid noise and fluorite ( CaF2 ) he wantsto compare, has low wear rate, and the high price. Cryolite and fluorite in thefriction material, is the coefficient of hardness is not high, but withincreasing friction effect of packing varieties.
