Taking natural anhydrate(anhydrous gypsumⅡ) as major raw material,adding composite activator for modification to adjust setting time,flexural strength and compression strength,then mixed and milled with proper amount of composite water-retention agent,fly ash and air entraining agent to obtain plastering gypsum .

以天然硬石膏为主要原料，掺加复合激发剂进行改性处理，调节凝结时间及抗折、抗压强度，然后辅以适量复合保水剂、粉煤灰掺合料、引气剂等，磨细混匀后即得到抹灰用的粉刷石膏。

The chemical activating mechanism of UA is that CG can stimulate pozzolanicity more effective than gypsum because of higher solubility and looser crystal structure; but CG has poor property on retardation setting, and this shortage can be solved by mixing with gypsum; CS can offer alkali activity, which can depolymerize silica and aluminum glass, and benefit for other activity methods and overcome the disadvantage of HF on setting time; Sodium sulfate improves early strength greatly but loses the final strength. NF can improve both early and final strengths.

联合激发技术的化学激发机理是，煅烧石膏溶解度高及晶体结构松弛，比天然石膏的活性激发效率高，但降低石膏的缓凝作用，与天然石膏混合既可提高活性又能保持缓凝作用；干法电石渣提供碱激发，促进高钙灰中硅、铝玻璃体解聚，并克服高钙灰对凝结时间的不利影响；硫酸钠虽然早强作用明显，但使后期强度倒缩，NF使各龄期活性都得到提高；磨细的物理激发使高钙灰大颗粒中的CaO和富集碳组分被磨细、分散，活性增加而危害性降低。
