解決方(fang)案(an)
天然二(er)水(shui)石(shi)(shi)(shi)(shi)(shi)膏(gao)（CaSO4·2H2O）又稱(cheng)為(wei)生(sheng)石(shi)(shi)(shi)(shi)(shi)膏(gao)，經過煅燒、磨細(xi)可(ke)得β型半水(shui)石(shi)(shi)(shi)(shi)(shi)膏(gao)（CaSO4·1/2H2O），即(ji)建筑(zhu)石(shi)(shi)(shi)(shi)(shi)膏(gao)，又稱(cheng)熟石(shi)(shi)(shi)(shi)(shi)膏(gao)、灰泥。若(ruo)煅燒溫(wen)度(du)為(wei)190 °C可(ke)得模型石(shi)(shi)(shi)(shi)(shi)膏(gao)，其(qi)細(xi)度(du)和(he)白度(du)均比建筑(zhu)石(shi)(shi)(shi)(shi)(shi)膏(gao)高。若(ruo)將生(sheng)石(shi)(shi)(shi)(shi)(shi)膏(gao)在400-500 °C或(huo)高于800 °C下煅燒，即(ji)得地(di)板(ban)石(shi)(shi)(shi)(shi)(shi)膏(gao)，其(qi)凝結、硬化(hua)較慢，但硬化(hua)后強度(du)、耐磨性(xing)和(he)耐水(shui)性(xing)均較普通(tong)建筑(zhu)石(shi)(shi)(shi)(shi)(shi)膏(gao)為(wei)好。通(tong)常為(wei)白色(se)、無色(se)，無色(se)透明晶體稱(cheng)為(wei)透石(shi)(shi)(shi)(shi)(shi)膏(gao)，有時因(yin)含雜(za)質而成(cheng)灰、淺(qian)(qian)黃、淺(qian)(qian)褐等色(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(lie)開成(cheng)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)，可得(de)到(dao)半(ban)水(shui)(shui)石(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)。 α型(xing)(xing)(xing)半(ban)水(shui)(shui)石(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)結(jie)(jie)晶(jing)(jing)良好(hao)(hao)、堅(jian)實； β型(xing)(xing)(xing)半(ban)水(shui)(shui)石(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)是(shi)片狀并有裂(lie)紋的(de)(de)晶(jing)(jing)體，結(jie)(jie)晶(jing)(jing)很細(xi)，比(bi)表(biao)面積(ji)比(bi) α型(xing)(xing)(xing)半(ban)水(shui)(shui)石(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)大得(de)多。生產石(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)制品時， α型(xing)(xing)(xing)半(ban)水(shui)(shui)石(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)比(bi) β型(xing)(xing)(xing)需(xu)水(shui)(shui)量少(shao)，制品有較高的(de)(de)密(mi)實度和(he)強度。通常用蒸(zheng)壓釜在飽和(he)蒸(zheng)汽介質中(zhong)蒸(zheng)煉而(er)成(cheng)的(de)(de)是(shi) α型(xing)(xing)(xing)半(ban)水(shui)(shui)石(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)，也(ye)稱高強石(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)；用炒(chao)鍋或回(hui)轉窯敞開裝置煅煉而(er)成(cheng)的(de)(de)是(shi)β型(xing)(xing)(xing)半(ban)水(shui)(shui)石(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)，亦即建(jian)筑石(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)。半(ban)水(shui)(shui)石(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)與水(shui)(shui)拌和(he)的(de)(de)漿體重新形(xing)成(cheng)二水(shui)(shui)石(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)、在干燥過程中(zhong)迅速凝結(jie)(jie)硬(ying)化而(er)獲得(de)強度，但(dan)遇水(shui)(shui)則軟(ruan)化。石(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)是(shi)生產石(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)膠(jiao)(jiao)凝材料(liao)和(he)石(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)建(jian)筑制品的(de)(de)主(zhu)要原(yuan)料(liao)，也(ye)是(shi)硅酸鹽水(shui)(shui)泥的(de)(de)緩凝劑。石(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)經(jing)600～800°C煅燒(shao)(shao)后，加入(ru)少(shao)量石(shi)(shi)(shi)(shi)灰等(deng)催化劑共同磨(mo)細(xi)，可以得(de)到(dao)硬(ying)石(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)膠(jiao)(jiao)結(jie)(jie)料(liao)（也(ye)稱金氏膠(jiao)(jiao)結(jie)(jie)料(liao)）；經(jing)900～1000°C煅燒(shao)(shao)并磨(mo)細(xi)，可以得(de)到(dao)高溫煅燒(shao)(shao)石(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)。用這兩種石(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)制得(de)的(de)(de)制品，強度高于建(jian)筑石(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)制品，而(er)且硬(ying)石(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)膠(jiao)(jiao)結(jie)(jie)料(liao)有較好(hao)(hao)的(de)(de)隔熱性(xing)，高溫煅燒(shao)(shao)石(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)有較好(hao)(hao)的(de)(de)耐磨(mo)性(xing)和(he)抗水(shui)(shui)性(xing)。
