产品介绍
闭孔珍珠岩(又称玻化珍珠岩),该产品精选特殊粒径要求的矿砂,在电炉加热方式下膨化,通过对温度和物料滞空时间的精确控制,使产品表面溶融,气孔封闭,而内部为蜂窝状结构,外观呈微球型.与传统多孔珍珠岩相比,除保留了保温,绝热,隔音的特性外,更具有强度高,吸水率低,易和性好的特点。
Product introduction
Perlite obturator perlite (also called bo), the product selection of special particle size of ore, bulking under electric furnace heating mode, through the accurate control of temperature and empty material time, make the product surface melt, stomata closed, and internal to the honeycomb structure, the appearance is slightly ball. Compared with the traditional expanded perlite, in addition to retain the heat preservation, adiabatic, sound insulation of features, has high strength, bibulous rate is low, easy and good characteristics.
主要特性
该产品具有强度高,吸水率低,易分散等特点。
The main features
The product has high strength, bibulous rate is low, etc.
