Golden vermiculite
产品类别有金黄色蛭石,银白色蛭石;品种有蛭石片,蛭石粉,园艺蛭石,混合膨胀蛭石等。主要型号有:1-3mm,2-4mm,3-5mm 4-8mm 10-20目,20-40目,40-60目,80-120目等。
一、 蛭石的性质与结构
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M g × (H2O)[Mg3 × (AlSiO3O10)(H2O)]
化学成分为:
分子式 SiO2 MgO Al2O3 Fe2O3 H2O CaO PH
名称 二氧化硅 氧化镁 三氧化铝 三氧化铁 水 氧化钙 值
含量 % 37-42 11-23 9-17 3.5-15 5-11 1-2 7-1
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。
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,具有很强的保温隔热性能。
