膨胀珍珠岩制品是近年来发展较快的一种廉价高效保温制品。当前国内生产的品种主要有水泥珍珠岩制品、沥青珍珠岩制品和水玻璃珍珠岩制品等,被广泛用于工业保温,热力管线绝热及房屋建筑等郜门,但是由于这些电制品强度较低,特别是抗折强度低,在运输搬运施工中损失高达30～40％,其重复使用率也很低,因而大大缩小了应用领域。目前膨胀珍珠岩制品在国外已全部被纤维 Expanded perlite products are a kind of cheap and efficient thermal insulation products that have developed rapidly in recent years. At present, domestically produced varieties mainly include cement perlite products, asphalt perlite products, and water glass perlite products. They are widely used in industrial insulation, thermal insulation, and building construction, but due to the low strength of these electric products, In particular, the low flexural strength, the loss of up to 30-40% in the transportation and transportation construction, and its low reuse rate, thus greatly reducing the application field. At present, expanded perlite products have been completely
