摘要
本文通过对电石渣的危害分析,利用电石渣-稀酸中和反应机理制备高强度石膏,实现“变废为宝”,介绍了电石渣与稀酸反应制备主要工艺流程,分析了高强石膏市场应用情况。
The harm of carbide slag is analyzed in this paper,and it also deals with how to prepare high strength gypsum by neutralizing carbide slag and waste dilute acid so that the waste can be changed into resources.The main technological process of preparing high strength gypsum by reaction of carbide slag with sulphuric acid was introduced,and then analyzed the application of high strength gypsum.
