        注:可以按照客户的需求生产不同白度、纯度、细度的硅灰石粉。    

    

        2、产品主要用途     

    

              广泛用于复合材料(电子元件、封装材料、高性能橡胶制品、汽车壳体、模具)、造纸、陶瓷、建材、橡胶、塑料、油漆、涂料、化工、电焊条、尼龙、冶金保护渣以及作为石棉代用品等领域。    

    

        3、产品主要作用    

    

            使用在塑料中可以提高产品的冲击强度、增强流动性以及改善抗拉强度、线性拉伸及模收缩率。    

    

            使用在涂料中具有一种良好的补强性,既可以提高涂料的韧性和耐用性,又可以保持涂料表面平整与及良好的光 泽度。而且提高了抗洗刷和抗风化性能,还可减少涂料与油墨的吸油量并保持碱性,具有抗腐蚀能力。可以得到高质量颜色明亮的涂料,并具有良好的均涂性和抗老 化性能。使涂料可以得到更好的机械强度、增加耐久性、增强粘附力和抗腐蚀性能。还有良好的覆盖率、附着力。    

    

            在陶瓷应用中,可增加陶瓷坯体和陶瓷制品的强度,减少陶瓷的碎裂和釉面斑点,增加釉料表面光泽,还可降低燃料的消耗(可节省燃料 60%);用于陶瓷和玻璃制造中过程中的氧化钙和二氧化硅的原料以及冶金工业的低温熔剂等。
