解(jie)決方(fang)案
天然二水(shui)石(shi)(shi)(shi)膏(gao)(gao)(gao)(gao)（CaSO4·2H2O）又稱為(wei)生石(shi)(shi)(shi)膏(gao)(gao)(gao)(gao)，經過煅(duan)燒(shao)、磨細可(ke)得(de)β型(xing)半(ban)水(shui)石(shi)(shi)(shi)膏(gao)(gao)(gao)(gao)（CaSO4·1/2H2O），即建筑石(shi)(shi)(shi)膏(gao)(gao)(gao)(gao)，又稱熟石(shi)(shi)(shi)膏(gao)(gao)(gao)(gao)、灰(hui)泥。若煅(duan)燒(shao)溫度(du)為(wei)190 °C可(ke)得(de)模型(xing)石(shi)(shi)(shi)膏(gao)(gao)(gao)(gao)，其(qi)細度(du)和白度(du)均比建筑石(shi)(shi)(shi)膏(gao)(gao)(gao)(gao)高(gao)。若將生石(shi)(shi)(shi)膏(gao)(gao)(gao)(gao)在400-500 °C或(huo)高(gao)于800 °C下(xia)煅(duan)燒(shao)，即得(de)地板石(shi)(shi)(shi)膏(gao)(gao)(gao)(gao)，其(qi)凝結(jie)、硬(ying)化(hua)較慢，但硬(ying)化(hua)后強度(du)、耐磨性和耐水(shui)性均較普通建筑石(shi)(shi)(shi)膏(gao)(gao)(gao)(gao)為(wei)好。通常為(wei)白色、無色，無色透明(ming)晶體稱為(wei)透石(shi)(shi)(shi)膏(gao)(gao)(gao)(gao)，有時因含雜質而(er)成灰(hui)、淺黃、淺褐等色。
