解決方(fang)案
天然二水(shui)石(shi)(shi)(shi)(shi)膏(gao)（CaSO4·2H2O）又稱為(wei)(wei)(wei)生(sheng)石(shi)(shi)(shi)(shi)膏(gao)，經過煅燒(shao)(shao)、磨(mo)細可(ke)(ke)得(de)β型半水(shui)石(shi)(shi)(shi)(shi)膏(gao)（CaSO4·1/2H2O），即建(jian)筑(zhu)石(shi)(shi)(shi)(shi)膏(gao)，又稱熟(shu)石(shi)(shi)(shi)(shi)膏(gao)、灰泥。若煅燒(shao)(shao)溫(wen)度(du)(du)為(wei)(wei)(wei)190 °C可(ke)(ke)得(de)模(mo)型石(shi)(shi)(shi)(shi)膏(gao)，其細度(du)(du)和(he)白度(du)(du)均比建(jian)筑(zhu)石(shi)(shi)(shi)(shi)膏(gao)高。若將(jiang)生(sheng)石(shi)(shi)(shi)(shi)膏(gao)在400-500 °C或(huo)高于800 °C下(xia)煅燒(shao)(shao)，即得(de)地板石(shi)(shi)(shi)(shi)膏(gao)，其凝結、硬化(hua)較(jiao)慢，但硬化(hua)后強度(du)(du)、耐(nai)磨(mo)性和(he)耐(nai)水(shui)性均較(jiao)普通建(jian)筑(zhu)石(shi)(shi)(shi)(shi)膏(gao)為(wei)(wei)(wei)好。通常為(wei)(wei)(wei)白色(se)、無色(se)，無色(se)透(tou)明晶體稱為(wei)(wei)(wei)透(tou)石(shi)(shi)(shi)(shi)膏(gao)，有時因含雜質(zhi)而成灰、淺黃、淺褐等色(se)。
石(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)屬單斜晶系，解理度(du)(du)很高(gao)(gao)，容易裂(lie)開(kai)(kai)成薄片(pian)。將石(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)加熱(re)100～200°C，失去部分(fen)結(jie)晶水(shui)，可(ke)(ke)得(de)(de)到(dao)(dao)半(ban)(ban)水(shui)石(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)。 α型(xing)(xing)半(ban)(ban)水(shui)石(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)結(jie)晶良好、堅(jian)實； β型(xing)(xing)半(ban)(ban)水(shui)石(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)是(shi)(shi)(shi)片(pian)狀并有裂(lie)紋的(de)晶體，結(jie)晶很細(xi)，比(bi)表面積比(bi) α型(xing)(xing)半(ban)(ban)水(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(zhi)(zhi)品時(shi)， α型(xing)(xing)半(ban)(ban)水(shui)石(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)比(bi) β型(xing)(xing)需水(shui)量(liang)少，制(zhi)(zhi)品有較(jiao)高(gao)(gao)的(de)密(mi)實度(du)(du)和強(qiang)度(du)(du)。通(tong)常用(yong)(yong)蒸壓釜在(zai)飽(bao)和蒸汽(qi)介質中蒸煉而成的(de)是(shi)(shi)(shi) α型(xing)(xing)半(ban)(ban)水(shui)石(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)，也稱(cheng)高(gao)(gao)強(qiang)石(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)；用(yong)(yong)炒鍋或回轉(zhuan)窯(yao)敞(chang)開(kai)(kai)裝置煅(duan)煉而成的(de)是(shi)(shi)(shi)β型(xing)(xing)半(ban)(ban)水(shui)石(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)，亦即建筑(zhu)石(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)。半(ban)(ban)水(shui)石(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)與(yu)水(shui)拌和的(de)漿體重新形成二水(shui)石(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)、在(zai)干燥過(guo)程中迅速凝結(jie)硬(ying)(ying)化而獲得(de)(de)強(qiang)度(du)(du)，但遇水(shui)則軟化。石(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)是(shi)(shi)(shi)生產石(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)膠凝材料(liao)(liao)(liao)和石(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)建筑(zhu)制(zhi)(zhi)品的(de)主要原料(liao)(liao)(liao)，也是(shi)(shi)(shi)硅酸鹽水(shui)泥的(de)緩凝劑。石(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)經600～800°C煅(duan)燒(shao)后，加入少量(liang)石(shi)(shi)(shi)(shi)灰(hui)等催(cui)化劑共(gong)同磨細(xi)，可(ke)(ke)以得(de)(de)到(dao)(dao)硬(ying)(ying)石(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)膠結(jie)料(liao)(liao)(liao)（也稱(cheng)金(jin)氏膠結(jie)料(liao)(liao)(liao)）；經900～1000°C煅(duan)燒(shao)并磨細(xi)，可(ke)(ke)以得(de)(de)到(dao)(dao)高(gao)(gao)溫(wen)煅(duan)燒(shao)石(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)。用(yong)(yong)這(zhe)兩(liang)種(zhong)石(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)制(zhi)(zhi)得(de)(de)的(de)制(zhi)(zhi)品，強(qiang)度(du)(du)高(gao)(gao)于建筑(zhu)石(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)制(zhi)(zhi)品，而且硬(ying)(ying)石(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)膠結(jie)料(liao)(liao)(liao)有較(jiao)好的(de)隔熱(re)性(xing)，高(gao)(gao)溫(wen)煅(duan)燒(shao)石(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)有較(jiao)好的(de)耐磨性(xing)和抗水(shui)性(xing)。
