蛭石 
     我厂专业生产保温防火材料专用蛭石，主要型号有:1-3mm,2-4mm,10-20目,20-40目,40-60目,80-120目等。 
     蛭石系列：  金黄色蛭石，银白色蛭石，蛭石片等 
 
       蛭石说明   
      蛭石是一种层状结构的含镁的水铝硅酸盐次生变质矿物，原矿外似云母，通常由黑（金）云母经热液蚀变作用或风化而成，因其受热失水膨胀时呈挠曲状，形态酷似水蛭，故称蛭石。  
蛭石的化学式为（Mg，Ca）0.7（Mg，Fe，Al）6.0[（Al，Si）8.0]（OH4.8H2O）  
      蛭石按阶段性划分为蛭石原矿和膨胀蛭石,按颜色分类可分为金黄色蛭石、银白色蛭石。乳白色蛭石。  
      我厂生产的蛭石原矿经过高温焙烧其体积可迅速膨胀8-20倍，膨胀后的比重130-180kg/m3。在防火保温具有良好的保温隔热性能。
