1.性能特點(diǎn):硅灰石具有針狀、纖維狀晶體形態(tài)及較高的白度和獨(dú)特的物理化學(xué)性能,可取代或部分取代玻璃纖維作為聚合物復(fù)合材料的增強(qiáng)體,提高材料性能,降低生產(chǎn)成本,起增重和增強(qiáng)補(bǔ)強(qiáng)作用。
Characteristics: the wollastonite has acicular, fibrous crystal form and high whiteness, unique physical and chemical properties, and can replace or partly replace glass fiber as the reinforced polymer composite material, which can improve the material performance, reduce production cost, gain weight and enhance reinforcing effect.
2.應(yīng)用領(lǐng)域:廣泛應(yīng)用于復(fù)合材料(電子元件、封裝材料、高性能橡膠制品。汽車殼體、模具)、陶瓷、油漆、涂料、塑料、橡膠、化工、造紙、電焊條、冶金保護(hù)渣以及作為石棉代用品等領(lǐng)域。
Application fields: widely used in composite material (electronic components, packaging materials, high performance rubber products. Motor shell, mold), ceramics, paint, coatings, plastics, rubber, chemical industry, paper making, welding electrode as asbestos substitute, metallurgical powder and etc.
