The data is shocking, and the massive output of fly ash and slag has seriously affected the ecological environment.
目前市场上，存在硅钙板水泥聚苯颗粒隔墙条板，由于水泥的水化特性，脱模时间长，养护时间长，大大限制了隔墙条板的生产产量。 At present, there are calcium silicate board cement polystyrene particle partition wall slats in the market. Due to the hydration characteristics of cement, the demoulding time is long and the curing time is long, which greatly limits the production output of partition wall slats.
本发明通过对工业副产石膏进行无机及有机改性，制备成初终凝时间短的胶凝材料，从而制备夹心复合轻质隔墙条板。 The invention prepares a gelling material with a short initial and final setting time through inorganic and organic modification of the industrial by-product gypsum, thereby preparing a sandwich composite lightweight partition wall strip.
