解決(jue)方案
天然二(er)水石(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(duan)(duan)燒(shao)、磨(mo)細可(ke)得β型(xing)半水石(shi)(shi)(shi)膏(gao)(gao)（CaSO4·1/2H2O），即建(jian)(jian)(jian)筑(zhu)(zhu)(zhu)石(shi)(shi)(shi)膏(gao)(gao)，又稱(cheng)(cheng)熟石(shi)(shi)(shi)膏(gao)(gao)、灰泥。若煅(duan)(duan)燒(shao)溫度為(wei)190 °C可(ke)得模(mo)型(xing)石(shi)(shi)(shi)膏(gao)(gao)，其細度和(he)白(bai)度均比建(jian)(jian)(jian)筑(zhu)(zhu)(zhu)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(yu)800 °C下煅(duan)(duan)燒(shao)，即得地板石(shi)(shi)(shi)膏(gao)(gao)，其凝結、硬化較慢(man)，但硬化后強度、耐磨(mo)性和(he)耐水性均較普通(tong)(tong)建(jian)(jian)(jian)筑(zhu)(zhu)(zhu)石(shi)(shi)(shi)膏(gao)(gao)為(wei)好。通(tong)(tong)常為(wei)白(bai)色(se)(se)、無色(se)(se)，無色(se)(se)透明晶(jing)體稱(cheng)(cheng)為(wei)透石(shi)(shi)(shi)膏(gao)(gao)，有時因含(han)雜(za)質而成灰、淺黃、淺褐等色(se)(se)。
石(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)屬單斜晶(jing)(jing)系，解理度很高，容易(yi)裂開成薄片。將石(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)加熱100～200°C，失去部分結(jie)(jie)晶(jing)(jing)水(shui)(shui)(shui)，可(ke)得(de)(de)到(dao)半(ban)水(shui)(shui)(shui)石(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)。 α型(xing)半(ban)水(shui)(shui)(shui)石(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)結(jie)(jie)晶(jing)(jing)良好(hao)、堅實； β型(xing)半(ban)水(shui)(shui)(shui)石(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)是(shi)片狀并(bing)有裂紋(wen)的(de)晶(jing)(jing)體，結(jie)(jie)晶(jing)(jing)很細，比(bi)表(biao)面(mian)積(ji)比(bi) α型(xing)半(ban)水(shui)(shui)(shui)石(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)大得(de)(de)多。生產石(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)制品(pin)(pin)時(shi)， α型(xing)半(ban)水(shui)(shui)(shui)石(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)比(bi) β型(xing)需水(shui)(shui)(shui)量少，制品(pin)(pin)有較(jiao)高的(de)密實度和(he)(he)強(qiang)度。通常用(yong)蒸壓釜在飽和(he)(he)蒸汽(qi)介質中(zhong)蒸煉(lian)而成的(de)是(shi) α型(xing)半(ban)水(shui)(shui)(shui)石(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)，也稱高強(qiang)石(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)；用(yong)炒鍋或回轉窯(yao)敞開裝(zhuang)置煅(duan)(duan)煉(lian)而成的(de)是(shi)β型(xing)半(ban)水(shui)(shui)(shui)石(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)，亦即建筑(zhu)(zhu)石(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)。半(ban)水(shui)(shui)(shui)石(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)與水(shui)(shui)(shui)拌(ban)和(he)(he)的(de)漿體重新形成二(er)水(shui)(shui)(shui)石(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)、在干燥過(guo)程(cheng)中(zhong)迅速凝(ning)結(jie)(jie)硬(ying)(ying)化(hua)而獲得(de)(de)強(qiang)度，但遇水(shui)(shui)(shui)則軟化(hua)。石(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)是(shi)生產石(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)膠(jiao)凝(ning)材料(liao)和(he)(he)石(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)建筑(zhu)(zhu)制品(pin)(pin)的(de)主要原料(liao)，也是(shi)硅酸鹽(yan)水(shui)(shui)(shui)泥的(de)緩凝(ning)劑。石(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)經600～800°C煅(duan)(duan)燒(shao)后，加入少量石(shi)(shi)(shi)(shi)灰等催化(hua)劑共同(tong)磨細，可(ke)以得(de)(de)到(dao)硬(ying)(ying)石(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)膠(jiao)結(jie)(jie)料(liao)（也稱金氏(shi)膠(jiao)結(jie)(jie)料(liao)）；經900～1000°C煅(duan)(duan)燒(shao)并(bing)磨細，可(ke)以得(de)(de)到(dao)高溫(wen)煅(duan)(duan)燒(shao)石(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)。用(yong)這兩種(zhong)石(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)制得(de)(de)的(de)制品(pin)(pin)，強(qiang)度高于建筑(zhu)(zhu)石(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)制品(pin)(pin)，而且硬(ying)(ying)石(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)膠(jiao)結(jie)(jie)料(liao)有較(jiao)好(hao)的(de)隔熱性，高溫(wen)煅(duan)(duan)燒(shao)石(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)有較(jiao)好(hao)的(de)耐磨性和(he)(he)抗水(shui)(shui)(shui)性。
