解決(jue)方案
天然二水(shui)石(shi)(shi)(shi)膏(gao)(gao)（CaSO4·2H2O）又稱(cheng)(cheng)為(wei)生(sheng)石(shi)(shi)(shi)膏(gao)(gao)，經過煅燒、磨細可得β型半水(shui)石(shi)(shi)(shi)膏(gao)(gao)（CaSO4·1/2H2O），即(ji)建(jian)筑石(shi)(shi)(shi)膏(gao)(gao)，又稱(cheng)(cheng)熟石(shi)(shi)(shi)膏(gao)(gao)、灰泥。若煅燒溫度為(wei)190 °C可得模型石(shi)(shi)(shi)膏(gao)(gao)，其細度和白(bai)度均(jun)比建(jian)筑石(shi)(shi)(shi)膏(gao)(gao)高。若將生(sheng)石(shi)(shi)(shi)膏(gao)(gao)在400-500 °C或高于800 °C下煅燒，即(ji)得地板石(shi)(shi)(shi)膏(gao)(gao)，其凝結、硬(ying)化(hua)較慢，但硬(ying)化(hua)后強(qiang)度、耐磨性和耐水(shui)性均(jun)較普通建(jian)筑石(shi)(shi)(shi)膏(gao)(gao)為(wei)好。通常(chang)為(wei)白(bai)色(se)、無(wu)色(se)，無(wu)色(se)透(tou)明晶體稱(cheng)(cheng)為(wei)透(tou)石(shi)(shi)(shi)膏(gao)(gao)，有時因含雜質而成灰、淺黃、淺褐等(deng)色(se)。
石(shi)(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)(gao)(gao)屬單(dan)斜晶系(xi)，解理度(du)很高(gao)(gao)，容易裂(lie)(lie)開成(cheng)(cheng)薄(bo)片(pian)。將石(shi)(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)(gao)(gao)加熱(re)100～200°C，失去部分結晶水(shui)，可(ke)(ke)得(de)(de)(de)到半(ban)水(shui)石(shi)(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)(gao)(gao)。 α型(xing)(xing)半(ban)水(shui)石(shi)(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)(gao)(gao)結晶良好、堅實； β型(xing)(xing)半(ban)水(shui)石(shi)(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)(gao)(gao)是片(pian)狀并有(you)(you)裂(lie)(lie)紋的(de)晶體，結晶很細，比表面(mian)積比 α型(xing)(xing)半(ban)水(shui)石(shi)(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)(gao)(gao)大得(de)(de)(de)多。生產石(shi)(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)(gao)(gao)制(zhi)品時， α型(xing)(xing)半(ban)水(shui)石(shi)(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)(gao)(gao)比 β型(xing)(xing)需水(shui)量少，制(zhi)品有(you)(you)較(jiao)高(gao)(gao)的(de)密實度(du)和(he)強度(du)。通常(chang)用蒸(zheng)壓(ya)釜在飽和(he)蒸(zheng)汽介質中蒸(zheng)煉而成(cheng)(cheng)的(de)是 α型(xing)(xing)半(ban)水(shui)石(shi)(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)(gao)(gao)，也稱高(gao)(gao)強石(shi)(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)(gao)(gao)；用炒鍋或回轉窯敞(chang)開裝置煅(duan)煉而成(cheng)(cheng)的(de)是β型(xing)(xing)半(ban)水(shui)石(shi)(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)(gao)(gao)，亦即建筑石(shi)(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)(gao)(gao)。半(ban)水(shui)石(shi)(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)(gao)(gao)與水(shui)拌和(he)的(de)漿體重(zhong)新形成(cheng)(cheng)二水(shui)石(shi)(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)(gao)(gao)、在干燥過(guo)程中迅速凝(ning)結硬化而獲得(de)(de)(de)強度(du)，但(dan)遇水(shui)則軟化。石(shi)(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)(gao)(gao)是生產石(shi)(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)(gao)(gao)膠凝(ning)材料(liao)和(he)石(shi)(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)(gao)(gao)建筑制(zhi)品的(de)主要原料(liao)，也是硅酸鹽水(shui)泥的(de)緩凝(ning)劑(ji)。石(shi)(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)(gao)(gao)經600～800°C煅(duan)燒后，加入少量石(shi)(shi)(shi)(shi)(shi)灰等催(cui)化劑(ji)共同磨細，可(ke)(ke)以得(de)(de)(de)到硬石(shi)(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)(gao)(gao)膠結料(liao)（也稱金氏膠結料(liao)）；經900～1000°C煅(duan)燒并磨細，可(ke)(ke)以得(de)(de)(de)到高(gao)(gao)溫煅(duan)燒石(shi)(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)(gao)(gao)。用這兩種石(shi)(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)(gao)(gao)制(zhi)得(de)(de)(de)的(de)制(zhi)品，強度(du)高(gao)(gao)于建筑石(shi)(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)(gao)(gao)制(zhi)品，而且硬石(shi)(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)(gao)(gao)膠結料(liao)有(you)(you)較(jiao)好的(de)隔熱(re)性(xing)，高(gao)(gao)溫煅(duan)燒石(shi)(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)(gao)(gao)有(you)(you)較(jiao)好的(de)耐磨性(xing)和(he)抗(kang)水(shui)性(xing)。
