解決(jue)方案
天然二水(shui)石(shi)(shi)膏(gao)(gao)（CaSO4·2H2O）又稱為生石(shi)(shi)膏(gao)(gao)，經過煅(duan)燒(shao)、磨細可(ke)得(de)β型(xing)(xing)半水(shui)石(shi)(shi)膏(gao)(gao)（CaSO4·1/2H2O），即建(jian)(jian)筑石(shi)(shi)膏(gao)(gao)，又稱熟石(shi)(shi)膏(gao)(gao)、灰(hui)泥(ni)。若煅(duan)燒(shao)溫度(du)為190 °C可(ke)得(de)模型(xing)(xing)石(shi)(shi)膏(gao)(gao)，其細度(du)和(he)白度(du)均(jun)比建(jian)(jian)筑石(shi)(shi)膏(gao)(gao)高(gao)。若將生石(shi)(shi)膏(gao)(gao)在400-500 °C或高(gao)于800 °C下煅(duan)燒(shao)，即得(de)地板(ban)石(shi)(shi)膏(gao)(gao)，其凝結、硬化較慢，但(dan)硬化后強(qiang)度(du)、耐磨性和(he)耐水(shui)性均(jun)較普通建(jian)(jian)筑石(shi)(shi)膏(gao)(gao)為好(hao)。通常(chang)為白色(se)、無(wu)色(se)，無(wu)色(se)透(tou)明晶體(ti)稱為透(tou)石(shi)(shi)膏(gao)(gao)，有時因含雜質而成灰(hui)、淺黃、淺褐等色(se)。
石(shi)(shi)(shi)膏(gao)(gao)(gao)(gao)屬單斜晶(jing)(jing)系，解理度(du)很(hen)(hen)高，容易裂開成薄片(pian)(pian)。將石(shi)(shi)(shi)膏(gao)(gao)(gao)(gao)加熱100～200°C，失去(qu)部分(fen)結(jie)晶(jing)(jing)水(shui)(shui)(shui)，可(ke)(ke)得到半(ban)(ban)水(shui)(shui)(shui)石(shi)(shi)(shi)膏(gao)(gao)(gao)(gao)。 α型半(ban)(ban)水(shui)(shui)(shui)石(shi)(shi)(shi)膏(gao)(gao)(gao)(gao)結(jie)晶(jing)(jing)良好(hao)、堅(jian)實； β型半(ban)(ban)水(shui)(shui)(shui)石(shi)(shi)(shi)膏(gao)(gao)(gao)(gao)是(shi)(shi)片(pian)(pian)狀并(bing)有(you)裂紋的晶(jing)(jing)體，結(jie)晶(jing)(jing)很(hen)(hen)細(xi)，比表面積(ji)比 α型半(ban)(ban)水(shui)(shui)(shui)石(shi)(shi)(shi)膏(gao)(gao)(gao)(gao)大得多。生產石(shi)(shi)(shi)膏(gao)(gao)(gao)(gao)制(zhi)(zhi)品(pin)(pin)時(shi)， α型半(ban)(ban)水(shui)(shui)(shui)石(shi)(shi)(shi)膏(gao)(gao)(gao)(gao)比 β型需水(shui)(shui)(shui)量少(shao)，制(zhi)(zhi)品(pin)(pin)有(you)較(jiao)高的密實度(du)和(he)強度(du)。通常用蒸壓釜在飽和(he)蒸汽介質中(zhong)蒸煉(lian)而成的是(shi)(shi) α型半(ban)(ban)水(shui)(shui)(shui)石(shi)(shi)(shi)膏(gao)(gao)(gao)(gao)，也(ye)稱(cheng)(cheng)高強石(shi)(shi)(shi)膏(gao)(gao)(gao)(gao)；用炒鍋或回轉窯敞(chang)開裝置煅煉(lian)而成的是(shi)(shi)β型半(ban)(ban)水(shui)(shui)(shui)石(shi)(shi)(shi)膏(gao)(gao)(gao)(gao)，亦即建(jian)筑(zhu)石(shi)(shi)(shi)膏(gao)(gao)(gao)(gao)。半(ban)(ban)水(shui)(shui)(shui)石(shi)(shi)(shi)膏(gao)(gao)(gao)(gao)與水(shui)(shui)(shui)拌和(he)的漿體重新形成二水(shui)(shui)(shui)石(shi)(shi)(shi)膏(gao)(gao)(gao)(gao)、在干燥過程中(zhong)迅速凝(ning)結(jie)硬化而獲得強度(du)，但(dan)遇水(shui)(shui)(shui)則軟化。石(shi)(shi)(shi)膏(gao)(gao)(gao)(gao)是(shi)(shi)生產石(shi)(shi)(shi)膏(gao)(gao)(gao)(gao)膠凝(ning)材料和(he)石(shi)(shi)(shi)膏(gao)(gao)(gao)(gao)建(jian)筑(zhu)制(zhi)(zhi)品(pin)(pin)的主要原料，也(ye)是(shi)(shi)硅酸鹽水(shui)(shui)(shui)泥(ni)的緩凝(ning)劑(ji)(ji)。石(shi)(shi)(shi)膏(gao)(gao)(gao)(gao)經600～800°C煅燒(shao)(shao)后(hou)，加入少(shao)量石(shi)(shi)(shi)灰等催化劑(ji)(ji)共同磨(mo)細(xi)，可(ke)(ke)以得到硬石(shi)(shi)(shi)膏(gao)(gao)(gao)(gao)膠結(jie)料（也(ye)稱(cheng)(cheng)金氏(shi)膠結(jie)料）；經900～1000°C煅燒(shao)(shao)并(bing)磨(mo)細(xi)，可(ke)(ke)以得到高溫(wen)煅燒(shao)(shao)石(shi)(shi)(shi)膏(gao)(gao)(gao)(gao)。用這兩種石(shi)(shi)(shi)膏(gao)(gao)(gao)(gao)制(zhi)(zhi)得的制(zhi)(zhi)品(pin)(pin)，強度(du)高于建(jian)筑(zhu)石(shi)(shi)(shi)膏(gao)(gao)(gao)(gao)制(zhi)(zhi)品(pin)(pin)，而且硬石(shi)(shi)(shi)膏(gao)(gao)(gao)(gao)膠結(jie)料有(you)較(jiao)好(hao)的隔熱性，高溫(wen)煅燒(shao)(shao)石(shi)(shi)(shi)膏(gao)(gao)(gao)(gao)有(you)較(jiao)好(hao)的耐磨(mo)性和(he)抗水(shui)(shui)(shui)性。
