摘要
研究了制备晶体石硫合剂的实验方法和最佳条件。原料质量为CaO∶S∶H2 O =1∶1 9∶6 ,常压微沸 45min ,水剂低温脱水密度达 1 38g/ml,- 10℃低温结晶。可得到CaS4 含量大于
The experimental method and the optimal process conditions for the production of crystal calcium polysulfide is studied.It includes raw material mass ratio CaO∶S∶H 2O=1∶1.9∶6,small boiling for 45 min at atmospheric pressure,the density of the solution should amount to 1.38 g/ml by dehydrate in low temperature,crystallizing in -10 ℃.The product that CaS 4 content over 47% is obtained.
