解決方案
天然二(er)水石(shi)(shi)(shi)膏(gao)(gao)(gao)（CaSO4·2H2O）又(you)稱(cheng)為生石(shi)(shi)(shi)膏(gao)(gao)(gao)，經過煅(duan)燒(shao)、磨細(xi)可得β型(xing)半水石(shi)(shi)(shi)膏(gao)(gao)(gao)（CaSO4·1/2H2O），即建(jian)筑(zhu)石(shi)(shi)(shi)膏(gao)(gao)(gao)，又(you)稱(cheng)熟石(shi)(shi)(shi)膏(gao)(gao)(gao)、灰泥。若煅(duan)燒(shao)溫度(du)為190 °C可得模型(xing)石(shi)(shi)(shi)膏(gao)(gao)(gao)，其細(xi)度(du)和(he)白(bai)度(du)均(jun)比(bi)建(jian)筑(zhu)石(shi)(shi)(shi)膏(gao)(gao)(gao)高。若將生石(shi)(shi)(shi)膏(gao)(gao)(gao)在400-500 °C或(huo)高于800 °C下煅(duan)燒(shao)，即得地板石(shi)(shi)(shi)膏(gao)(gao)(gao)，其凝結(jie)、硬(ying)化(hua)較慢，但硬(ying)化(hua)后強度(du)、耐磨性和(he)耐水性均(jun)較普通建(jian)筑(zhu)石(shi)(shi)(shi)膏(gao)(gao)(gao)為好。通常為白(bai)色、無色，無色透明晶體稱(cheng)為透石(shi)(shi)(shi)膏(gao)(gao)(gao)，有時(shi)因含雜質而成(cheng)灰、淺黃(huang)、淺褐等色。
石(shi)(shi)(shi)(shi)膏(gao)屬(shu)單斜晶(jing)系，解理度(du)很高(gao)，容易裂(lie)開成(cheng)薄(bo)片。將石(shi)(shi)(shi)(shi)膏(gao)加熱100～200°C，失(shi)去(qu)部分結(jie)(jie)晶(jing)水(shui)(shui)，可得(de)(de)到(dao)半(ban)(ban)(ban)(ban)水(shui)(shui)石(shi)(shi)(shi)(shi)膏(gao)。 α型(xing)(xing)(xing)半(ban)(ban)(ban)(ban)水(shui)(shui)石(shi)(shi)(shi)(shi)膏(gao)結(jie)(jie)晶(jing)良好、堅(jian)實； β型(xing)(xing)(xing)半(ban)(ban)(ban)(ban)水(shui)(shui)石(shi)(shi)(shi)(shi)膏(gao)是(shi)片狀并有裂(lie)紋的(de)(de)(de)(de)(de)晶(jing)體(ti)，結(jie)(jie)晶(jing)很細(xi)，比表面積(ji)比 α型(xing)(xing)(xing)半(ban)(ban)(ban)(ban)水(shui)(shui)石(shi)(shi)(shi)(shi)膏(gao)大得(de)(de)多。生產石(shi)(shi)(shi)(shi)膏(gao)制(zhi)品(pin)時， α型(xing)(xing)(xing)半(ban)(ban)(ban)(ban)水(shui)(shui)石(shi)(shi)(shi)(shi)膏(gao)比 β型(xing)(xing)(xing)需水(shui)(shui)量少，制(zhi)品(pin)有較(jiao)高(gao)的(de)(de)(de)(de)(de)密實度(du)和(he)強度(du)。通常用(yong)蒸壓釜(fu)在飽和(he)蒸汽介質(zhi)中(zhong)蒸煉而(er)成(cheng)的(de)(de)(de)(de)(de)是(shi) α型(xing)(xing)(xing)半(ban)(ban)(ban)(ban)水(shui)(shui)石(shi)(shi)(shi)(shi)膏(gao)，也(ye)稱高(gao)強石(shi)(shi)(shi)(shi)膏(gao)；用(yong)炒鍋(guo)或回轉(zhuan)窯(yao)敞開裝置煅(duan)煉而(er)成(cheng)的(de)(de)(de)(de)(de)是(shi)β型(xing)(xing)(xing)半(ban)(ban)(ban)(ban)水(shui)(shui)石(shi)(shi)(shi)(shi)膏(gao)，亦(yi)即建(jian)筑(zhu)石(shi)(shi)(shi)(shi)膏(gao)。半(ban)(ban)(ban)(ban)水(shui)(shui)石(shi)(shi)(shi)(shi)膏(gao)與水(shui)(shui)拌和(he)的(de)(de)(de)(de)(de)漿體(ti)重新形成(cheng)二水(shui)(shui)石(shi)(shi)(shi)(shi)膏(gao)、在干(gan)燥過(guo)程中(zhong)迅速凝(ning)結(jie)(jie)硬(ying)化(hua)而(er)獲得(de)(de)強度(du)，但遇水(shui)(shui)則軟化(hua)。石(shi)(shi)(shi)(shi)膏(gao)是(shi)生產石(shi)(shi)(shi)(shi)膏(gao)膠凝(ning)材料(liao)和(he)石(shi)(shi)(shi)(shi)膏(gao)建(jian)筑(zhu)制(zhi)品(pin)的(de)(de)(de)(de)(de)主要原料(liao)，也(ye)是(shi)硅酸鹽水(shui)(shui)泥的(de)(de)(de)(de)(de)緩凝(ning)劑。石(shi)(shi)(shi)(shi)膏(gao)經600～800°C煅(duan)燒(shao)后(hou)，加入少量石(shi)(shi)(shi)(shi)灰等(deng)催化(hua)劑共同磨(mo)細(xi)，可以得(de)(de)到(dao)硬(ying)石(shi)(shi)(shi)(shi)膏(gao)膠結(jie)(jie)料(liao)（也(ye)稱金氏膠結(jie)(jie)料(liao)）；經900～1000°C煅(duan)燒(shao)并磨(mo)細(xi)，可以得(de)(de)到(dao)高(gao)溫(wen)煅(duan)燒(shao)石(shi)(shi)(shi)(shi)膏(gao)。用(yong)這(zhe)兩種石(shi)(shi)(shi)(shi)膏(gao)制(zhi)得(de)(de)的(de)(de)(de)(de)(de)制(zhi)品(pin)，強度(du)高(gao)于建(jian)筑(zhu)石(shi)(shi)(shi)(shi)膏(gao)制(zhi)品(pin)，而(er)且硬(ying)石(shi)(shi)(shi)(shi)膏(gao)膠結(jie)(jie)料(liao)有較(jiao)好的(de)(de)(de)(de)(de)隔熱性，高(gao)溫(wen)煅(duan)燒(shao)石(shi)(shi)(shi)(shi)膏(gao)有較(jiao)好的(de)(de)(de)(de)(de)耐(nai)磨(mo)性和(he)抗水(shui)(shui)性。
