摘要
氟石膏是化工生产排出的废渣,可替代天然石膏作为水泥缓凝剂使用,也可通过掺加外加剂将其改性,辅以其他掺合料用以生产抹灰用粉刷石膏、石膏砌块以及石膏砖等建筑材料,产品的技术性能指标均达到国家标准要求,且成本大大降低。这样既解决了环境污染问题,又实现了化工废渣的资源化利用,其社会效益和经济效益显著。
Fluor - gypsum is off - scum deriving from chemical production. It can replace natural gypsum used as a cement retarder and can also be used to produce such building materials as wall plastering gypsum, gypsum blocks, and gypsum bricks by adding other admixtures. The technical performance standard of this kind of product can not only meet the requirement of the state standard, but also decrease the production cost. As a result, not only the environment pollution problems are solved, and the chemical off- scum is recycled again as a useful resource, but also the social and economic benefits it brings are remarkable.
