解(jie)決方案
天(tian)然(ran)二(er)水(shui)石膏(gao)（CaSO4·2H2O）又稱為(wei)生石膏(gao)，經過煅燒(shao)、磨(mo)細(xi)可得β型半(ban)水(shui)石膏(gao)（CaSO4·1/2H2O），即建(jian)筑石膏(gao)，又稱熟石膏(gao)、灰(hui)泥。若煅燒(shao)溫度為(wei)190 °C可得模型石膏(gao)，其細(xi)度和白度均比建(jian)筑石膏(gao)高。若將生石膏(gao)在400-500 °C或高于(yu)800 °C下煅燒(shao)，即得地板石膏(gao)，其凝結(jie)、硬(ying)化較(jiao)慢，但硬(ying)化后(hou)強度、耐(nai)磨(mo)性和耐(nai)水(shui)性均較(jiao)普通建(jian)筑石膏(gao)為(wei)好。通常為(wei)白色(se)(se)、無色(se)(se)，無色(se)(se)透明晶體稱為(wei)透石膏(gao)，有時因(yin)含雜質而成灰(hui)、淺黃、淺褐等色(se)(se)。
石(shi)(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)屬單(dan)斜晶系，解(jie)理度(du)(du)很(hen)(hen)高(gao)(gao)(gao)，容易裂開成(cheng)薄(bo)片。將石(shi)(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)加熱(re)100～200°C，失去部分結(jie)(jie)(jie)晶水(shui)(shui)(shui)(shui)，可(ke)得(de)(de)到半(ban)(ban)(ban)水(shui)(shui)(shui)(shui)石(shi)(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)。 α型(xing)半(ban)(ban)(ban)水(shui)(shui)(shui)(shui)石(shi)(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)結(jie)(jie)(jie)晶良好(hao)、堅(jian)實(shi)； β型(xing)半(ban)(ban)(ban)水(shui)(shui)(shui)(shui)石(shi)(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)是(shi)片狀(zhuang)并(bing)有裂紋的(de)晶體，結(jie)(jie)(jie)晶很(hen)(hen)細，比(bi)表面積比(bi) α型(xing)半(ban)(ban)(ban)水(shui)(shui)(shui)(shui)石(shi)(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)大得(de)(de)多。生產石(shi)(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)制(zhi)(zhi)品時(shi)， α型(xing)半(ban)(ban)(ban)水(shui)(shui)(shui)(shui)石(shi)(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)比(bi) β型(xing)需水(shui)(shui)(shui)(shui)量少(shao)，制(zhi)(zhi)品有較高(gao)(gao)(gao)的(de)密實(shi)度(du)(du)和強(qiang)度(du)(du)。通常用蒸(zheng)壓(ya)釜在(zai)飽和蒸(zheng)汽介質(zhi)中(zhong)蒸(zheng)煉而成(cheng)的(de)是(shi) α型(xing)半(ban)(ban)(ban)水(shui)(shui)(shui)(shui)石(shi)(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)，也稱高(gao)(gao)(gao)強(qiang)石(shi)(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)；用炒鍋或(huo)回轉(zhuan)窯敞(chang)開裝置煅(duan)煉而成(cheng)的(de)是(shi)β型(xing)半(ban)(ban)(ban)水(shui)(shui)(shui)(shui)石(shi)(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)，亦即建(jian)(jian)筑(zhu)(zhu)石(shi)(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)。半(ban)(ban)(ban)水(shui)(shui)(shui)(shui)石(shi)(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)與水(shui)(shui)(shui)(shui)拌和的(de)漿體重(zhong)新形成(cheng)二水(shui)(shui)(shui)(shui)石(shi)(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)、在(zai)干燥過程中(zhong)迅速凝結(jie)(jie)(jie)硬化而獲得(de)(de)強(qiang)度(du)(du)，但(dan)遇水(shui)(shui)(shui)(shui)則(ze)軟化。石(shi)(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)是(shi)生產石(shi)(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)膠(jiao)凝材料(liao)(liao)和石(shi)(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)建(jian)(jian)筑(zhu)(zhu)制(zhi)(zhi)品的(de)主要原料(liao)(liao)，也是(shi)硅酸鹽水(shui)(shui)(shui)(shui)泥的(de)緩凝劑。石(shi)(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)經600～800°C煅(duan)燒(shao)后，加入少(shao)量石(shi)(shi)(shi)(shi)(shi)灰等催化劑共同磨細，可(ke)以得(de)(de)到硬石(shi)(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)膠(jiao)結(jie)(jie)(jie)料(liao)(liao)（也稱金氏膠(jiao)結(jie)(jie)(jie)料(liao)(liao)）；經900～1000°C煅(duan)燒(shao)并(bing)磨細，可(ke)以得(de)(de)到高(gao)(gao)(gao)溫煅(duan)燒(shao)石(shi)(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)。用這兩種(zhong)石(shi)(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)(gao)于(yu)建(jian)(jian)筑(zhu)(zhu)石(shi)(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)制(zhi)(zhi)品，而且硬石(shi)(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)膠(jiao)結(jie)(jie)(jie)料(liao)(liao)有較好(hao)的(de)隔(ge)熱(re)性(xing)，高(gao)(gao)(gao)溫煅(duan)燒(shao)石(shi)(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)有較好(hao)的(de)耐磨性(xing)和抗(kang)水(shui)(shui)(shui)(shui)性(xing)。
