摘要
在粉刷石膏浆料的制备中,用改性膨润土代替传统的有机保水剂甲基纤维素。试验表明,在缓凝剂掺量一定时,单掺改性膨润土的粉刷石膏加水拌合后,其保水性、强度和黏聚性等各项性能指标,均优于掺有甲基纤维素的粉刷石膏,文中还对保水机理进行了分析。
The application of modified bentonite in replace of conventional organic water-retention agent methyl cellulose in stucco gypsum was studied. The results showed that under a given delayed coagulant, water retentiveness and cohesive strength of stucco gypsum mixed with modified bentonite were higher than that of methyl cellulose. The water-retention mechanisms were analyzed based on experimental data.
