石膏专用耐水增强剂
摘要：
本发明公开了一种石膏专用耐水增强剂。该石膏专用耐水增强剂主要由无机水硬性胶凝材料和有机物减水剂组成；其中，有机物减水剂占无机水硬性胶凝材料重量的0.2～2％；该石膏专用耐水增强剂的细度为180～325目。本发明石膏专用耐水增强剂在不降低石膏干强度的情况下使石膏制品的湿强度和软化系数大幅度提高。
摘要（英）：

The invention discloses a special gypsum water-resistant reinforcing agent. The special gypsum water-resistant reinforcing agent is mainly composed of an inorganic hydraulic binding material and an organic water reducing agent; wherein, the organic water reducing agent is 0.2 to 2 percent weight of the inorganic hydraulic binding material; and the fineness of the special gypsum water-resistant reinforcing agent is 180 to 325 meshes. The special gypsum water-resistant reinforcing agent substantially increases the wet strength and coefficient of softening of gypsum products under the condition of not reducing the dry strength of gypsum.
