摘要
初步研究了水洗、石灰中和、浮选等不同预处理过程对高强石膏粉样品强度及晶体形貌的影响。结果表明:石灰中和预处理成本低,操作简单,无二次污染,样品强度可以达到17.2 MPa。
The pretreatments such as washing,neutralizing with quick lime,and floating were analyzed,and the influences of strength and crystal morphology on high-strength gypsum were preliminarily studied.The results showed that the cost of neutralizing with quick lime was low,its operation was simple,and the strength of the sample can achieve 17.2 MPa,with no pollution.
