解(jie)決(jue)方案
天然二水(shui)石(shi)(shi)(shi)膏(gao)(gao)（CaSO4·2H2O）又稱為(wei)(wei)生(sheng)石(shi)(shi)(shi)膏(gao)(gao)，經過煅(duan)(duan)燒(shao)(shao)、磨(mo)(mo)細(xi)可得β型半(ban)水(shui)石(shi)(shi)(shi)膏(gao)(gao)（CaSO4·1/2H2O），即(ji)建(jian)筑石(shi)(shi)(shi)膏(gao)(gao)，又稱熟石(shi)(shi)(shi)膏(gao)(gao)、灰泥。若煅(duan)(duan)燒(shao)(shao)溫(wen)度為(wei)(wei)190 °C可得模(mo)型石(shi)(shi)(shi)膏(gao)(gao)，其細(xi)度和白(bai)度均比建(jian)筑石(shi)(shi)(shi)膏(gao)(gao)高(gao)。若將(jiang)生(sheng)石(shi)(shi)(shi)膏(gao)(gao)在400-500 °C或高(gao)于800 °C下煅(duan)(duan)燒(shao)(shao)，即(ji)得地板石(shi)(shi)(shi)膏(gao)(gao)，其凝結、硬化較慢，但硬化后強度、耐(nai)磨(mo)(mo)性(xing)和耐(nai)水(shui)性(xing)均較普通建(jian)筑石(shi)(shi)(shi)膏(gao)(gao)為(wei)(wei)好。通常為(wei)(wei)白(bai)色(se)(se)(se)(se)、無(wu)色(se)(se)(se)(se)，無(wu)色(se)(se)(se)(se)透明晶(jing)體稱為(wei)(wei)透石(shi)(shi)(shi)膏(gao)(gao)，有時(shi)因含雜質(zhi)而成灰、淺黃、淺褐等色(se)(se)(se)(se)。
石(shi)(shi)(shi)(shi)(shi)膏(gao)(gao)屬單斜晶(jing)系(xi)，解理度(du)很高(gao)(gao)，容易裂開(kai)(kai)成(cheng)薄片。將石(shi)(shi)(shi)(shi)(shi)膏(gao)(gao)加熱(re)(re)100～200°C，失(shi)去部分結(jie)晶(jing)水(shui)(shui)(shui)，可(ke)得(de)(de)到(dao)半水(shui)(shui)(shui)石(shi)(shi)(shi)(shi)(shi)膏(gao)(gao)。 α型(xing)(xing)半水(shui)(shui)(shui)石(shi)(shi)(shi)(shi)(shi)膏(gao)(gao)結(jie)晶(jing)良好(hao)、堅(jian)實； β型(xing)(xing)半水(shui)(shui)(shui)石(shi)(shi)(shi)(shi)(shi)膏(gao)(gao)是(shi)片狀并有裂紋的(de)晶(jing)體，結(jie)晶(jing)很細，比(bi)(bi)表面(mian)積比(bi)(bi) α型(xing)(xing)半水(shui)(shui)(shui)石(shi)(shi)(shi)(shi)(shi)膏(gao)(gao)大得(de)(de)多。生產石(shi)(shi)(shi)(shi)(shi)膏(gao)(gao)制品(pin)時， α型(xing)(xing)半水(shui)(shui)(shui)石(shi)(shi)(shi)(shi)(shi)膏(gao)(gao)比(bi)(bi) β型(xing)(xing)需(xu)水(shui)(shui)(shui)量少，制品(pin)有較(jiao)(jiao)高(gao)(gao)的(de)密實度(du)和強(qiang)度(du)。通常(chang)用(yong)蒸壓釜(fu)在飽和蒸汽介質中(zhong)(zhong)蒸煉而成(cheng)的(de)是(shi) α型(xing)(xing)半水(shui)(shui)(shui)石(shi)(shi)(shi)(shi)(shi)膏(gao)(gao)，也(ye)稱高(gao)(gao)強(qiang)石(shi)(shi)(shi)(shi)(shi)膏(gao)(gao)；用(yong)炒鍋或回轉(zhuan)窯敞開(kai)(kai)裝置(zhi)煅煉而成(cheng)的(de)是(shi)β型(xing)(xing)半水(shui)(shui)(shui)石(shi)(shi)(shi)(shi)(shi)膏(gao)(gao)，亦即建(jian)筑石(shi)(shi)(shi)(shi)(shi)膏(gao)(gao)。半水(shui)(shui)(shui)石(shi)(shi)(shi)(shi)(shi)膏(gao)(gao)與水(shui)(shui)(shui)拌和的(de)漿體重新形成(cheng)二水(shui)(shui)(shui)石(shi)(shi)(shi)(shi)(shi)膏(gao)(gao)、在干燥過程中(zhong)(zhong)迅(xun)速凝結(jie)硬化而獲(huo)得(de)(de)強(qiang)度(du)，但遇水(shui)(shui)(shui)則軟化。石(shi)(shi)(shi)(shi)(shi)膏(gao)(gao)是(shi)生產石(shi)(shi)(shi)(shi)(shi)膏(gao)(gao)膠(jiao)凝材料和石(shi)(shi)(shi)(shi)(shi)膏(gao)(gao)建(jian)筑制品(pin)的(de)主要原料，也(ye)是(shi)硅酸鹽水(shui)(shui)(shui)泥的(de)緩(huan)凝劑。石(shi)(shi)(shi)(shi)(shi)膏(gao)(gao)經(jing)600～800°C煅燒后，加入少量石(shi)(shi)(shi)(shi)(shi)灰等催化劑共同(tong)磨細，可(ke)以(yi)得(de)(de)到(dao)硬石(shi)(shi)(shi)(shi)(shi)膏(gao)(gao)膠(jiao)結(jie)料（也(ye)稱金氏(shi)膠(jiao)結(jie)料）；經(jing)900～1000°C煅燒并磨細，可(ke)以(yi)得(de)(de)到(dao)高(gao)(gao)溫煅燒石(shi)(shi)(shi)(shi)(shi)膏(gao)(gao)。用(yong)這兩(liang)種石(shi)(shi)(shi)(shi)(shi)膏(gao)(gao)制得(de)(de)的(de)制品(pin)，強(qiang)度(du)高(gao)(gao)于建(jian)筑石(shi)(shi)(shi)(shi)(shi)膏(gao)(gao)制品(pin)，而且(qie)硬石(shi)(shi)(shi)(shi)(shi)膏(gao)(gao)膠(jiao)結(jie)料有較(jiao)(jiao)好(hao)的(de)隔(ge)熱(re)(re)性，高(gao)(gao)溫煅燒石(shi)(shi)(shi)(shi)(shi)膏(gao)(gao)有較(jiao)(jiao)好(hao)的(de)耐(nai)磨性和抗水(shui)(shui)(shui)性。
