在轻质保温材料的生产中,一个突出问题就是容重与强度的关系,既要轻质,又要高强,如何解决这对矛盾,使其真正做到容重轻强度高呢?日本在70年代中期到80年代初,集中了数家大公司和科研所,用了7年的时间,换了二代专利,终于获得解决,这就是固增强和封闭技术,被称之为划时代的增强技术。这种增强技术比增加压缩比、增加水泥用量都灵敏、因此,效果特别好。 近年来,我国对这项新技术也进行了研究,并有进展 1.珍珠岩的固化增强 In the production of lightweight thermal insulation materials, a prominent issue is the relationship between density and strength, which is both light and high-strength. How to resolve this contradiction and make it really light weight? Japan in the mid-1970s. By the early 1980s, several large companies and research institutes were concentrated, and it took seven years to replace the second-generation patent and finally solved it. This is the solid-enhanced and closed technology, which is called the epoch-making enhancement technology. This reinforcement technique is more sensitive than increasing the compression ratio and increasing the amount of cement, so the effect is particularly good. In recent years, China has also conducted research on this new technology and made progress. 1. The solidification of perlite has been enhanced.
