粉刷石膏复合缓凝剂正交实验分析

Orthogonal Experiments Analysis of Composite Retarders About Render Gy psum

利用正交试验,考察了复合缓凝剂对粉刷石膏的凝结时间、保水性、扩散度等性质的影响,确定了复合缓凝剂的最佳配比方案,使粉刷石膏的综合性能有较大提高。

Using orthogonal experiments,We study the properties of render gypsum,s uch as setting time,water retention and diffuse extent,when mixing into differen t quantities of composite retarders;and we get its best ratio,which can better i mprove composite property of render gypsum.
