前言膨胀珍珠岩是由酸性火山玻璃质熔岩(如珍珠岩、松脂岩、黑曜岩)经过破碎、予热、焙烧而制成的一种白色、多孔构造的粒状物料。以膨胀珍珠岩为骨料,用不同的胶结剂可以制成各种形状和性能的制品。膨胀珍珠岩及其制品具有重量轻、吸声、绝热性好、化学稳定性强、使用温度范围广、吸湿性小、不燃、不腐、耐酸、耐碱、无毒、无味等性能,因而可以广泛应用于建筑、化工、石油、冶金、电力、运输、国防及农业等部门,是一种很有发展前途的高效能轻质吸音、保温、隔热、保冷材料。一九七五年,陕西省陶瓷非金属矿研究所、西安冶金建筑学院、陕西省第二建筑设计
Introduction Expanded perlite is a white, porous structured granular material made from acidic volcanic vitreous lava (such as perlite, rosin, and obsidian) that has been crushed, preheated, and calcined. With expanded perlite as the aggregate, a variety of shapes and properties can be made with different binders. The expanded perlite and its products have the properties of light weight, sound absorption, good heat insulation, strong chemical stability, wide application temperature range, low moisture absorption, non-flammable, non-corrosive, acid-resistant, alkali-resistant, non-toxic, tasteless, etc. Widely used in the construction, chemical, petroleum, metallurgy, electric power, transportation, defense and agriculture sectors, it is a highly efficient, lightweight, sound-absorbing, heat-insulating, heat-insulating, and cold-reserving material.
