摘要
磷石膏的无害化处理及综合利用是固体废物处理与资源化领域的研究热点,也是磷化工持续发展的迫切需要。通过添加各种外加剂对磷建筑石膏进行改性并配制附加值较高的粉刷材料是其资源化利用的有效途径。粉刷材料工作性的好坏决定其能否更好地在工程中应用。重点研究了磷石膏基粉刷材料的凝结时间和保水性的影响因素。
The research on harmless treatment and multipurpose use of phosphogypsum is popular in the research field of solid waste disposal and recycling, which is also the needs of the sustainable development of phosphorus chemical industry. Modifying the phosphorus building gypsum by adding various additives and then preparing the high added value plaster material is an effective way to use the phosphogypsum as resources. Whether the plaster can be better used in engineering depends on its workability. In this paper, the influencing factors on the setting time and water retention of phosphogypsum-based plaster are studied.
