解決方(fang)案
天然(ran)二(er)水(shui)石(shi)(shi)(shi)膏(gao)(gao)(gao)(gao)（CaSO4·2H2O）又(you)稱為生石(shi)(shi)(shi)膏(gao)(gao)(gao)(gao)，經過(guo)煅(duan)燒(shao)、磨細可得(de)β型(xing)半(ban)水(shui)石(shi)(shi)(shi)膏(gao)(gao)(gao)(gao)（CaSO4·1/2H2O），即建筑石(shi)(shi)(shi)膏(gao)(gao)(gao)(gao)，又(you)稱熟石(shi)(shi)(shi)膏(gao)(gao)(gao)(gao)、灰泥(ni)。若煅(duan)燒(shao)溫(wen)度為190 °C可得(de)模型(xing)石(shi)(shi)(shi)膏(gao)(gao)(gao)(gao)，其(qi)細度和(he)白(bai)度均比(bi)建筑石(shi)(shi)(shi)膏(gao)(gao)(gao)(gao)高。若將(jiang)生石(shi)(shi)(shi)膏(gao)(gao)(gao)(gao)在(zai)400-500 °C或(huo)高于(yu)800 °C下煅(duan)燒(shao)，即得(de)地板石(shi)(shi)(shi)膏(gao)(gao)(gao)(gao)，其(qi)凝結、硬化較慢，但硬化后強(qiang)度、耐(nai)磨性和(he)耐(nai)水(shui)性均較普通建筑石(shi)(shi)(shi)膏(gao)(gao)(gao)(gao)為好。通常為白(bai)色(se)(se)、無色(se)(se)，無色(se)(se)透明晶體稱為透石(shi)(shi)(shi)膏(gao)(gao)(gao)(gao)，有時(shi)因含雜質而成灰、淺黃(huang)、淺褐等色(se)(se)。
石(shi)(shi)(shi)膏(gao)(gao)(gao)屬單斜晶(jing)系(xi)，解理度(du)很高，容(rong)易裂(lie)開成薄片。將石(shi)(shi)(shi)膏(gao)(gao)(gao)加(jia)(jia)熱100～200°C，失去(qu)部分結(jie)晶(jing)水(shui)，可得(de)到半(ban)(ban)水(shui)石(shi)(shi)(shi)膏(gao)(gao)(gao)。 α型(xing)半(ban)(ban)水(shui)石(shi)(shi)(shi)膏(gao)(gao)(gao)結(jie)晶(jing)良好、堅(jian)實(shi)； β型(xing)半(ban)(ban)水(shui)石(shi)(shi)(shi)膏(gao)(gao)(gao)是(shi)(shi)片狀(zhuang)并(bing)有(you)(you)裂(lie)紋的(de)晶(jing)體，結(jie)晶(jing)很細，比(bi)表面積(ji)比(bi) α型(xing)半(ban)(ban)水(shui)石(shi)(shi)(shi)膏(gao)(gao)(gao)大得(de)多。生(sheng)產石(shi)(shi)(shi)膏(gao)(gao)(gao)制(zhi)品(pin)(pin)時， α型(xing)半(ban)(ban)水(shui)石(shi)(shi)(shi)膏(gao)(gao)(gao)比(bi) β型(xing)需(xu)水(shui)量少，制(zhi)品(pin)(pin)有(you)(you)較(jiao)高的(de)密實(shi)度(du)和(he)(he)強(qiang)度(du)。通常用蒸壓(ya)釜在飽和(he)(he)蒸汽(qi)介質中蒸煉而(er)成的(de)是(shi)(shi) α型(xing)半(ban)(ban)水(shui)石(shi)(shi)(shi)膏(gao)(gao)(gao)，也稱(cheng)高強(qiang)石(shi)(shi)(shi)膏(gao)(gao)(gao)；用炒鍋(guo)或回(hui)轉窯敞開裝(zhuang)置煅(duan)(duan)(duan)煉而(er)成的(de)是(shi)(shi)β型(xing)半(ban)(ban)水(shui)石(shi)(shi)(shi)膏(gao)(gao)(gao)，亦即建筑石(shi)(shi)(shi)膏(gao)(gao)(gao)。半(ban)(ban)水(shui)石(shi)(shi)(shi)膏(gao)(gao)(gao)與水(shui)拌和(he)(he)的(de)漿體重(zhong)新形(xing)成二水(shui)石(shi)(shi)(shi)膏(gao)(gao)(gao)、在干(gan)燥過程中迅速凝結(jie)硬(ying)化而(er)獲得(de)強(qiang)度(du)，但遇水(shui)則(ze)軟(ruan)化。石(shi)(shi)(shi)膏(gao)(gao)(gao)是(shi)(shi)生(sheng)產石(shi)(shi)(shi)膏(gao)(gao)(gao)膠凝材料(liao)和(he)(he)石(shi)(shi)(shi)膏(gao)(gao)(gao)建筑制(zhi)品(pin)(pin)的(de)主要原料(liao)，也是(shi)(shi)硅酸鹽水(shui)泥的(de)緩凝劑(ji)。石(shi)(shi)(shi)膏(gao)(gao)(gao)經600～800°C煅(duan)(duan)(duan)燒(shao)后(hou)，加(jia)(jia)入少量石(shi)(shi)(shi)灰(hui)等催(cui)化劑(ji)共同磨(mo)細，可以(yi)得(de)到硬(ying)石(shi)(shi)(shi)膏(gao)(gao)(gao)膠結(jie)料(liao)（也稱(cheng)金氏膠結(jie)料(liao)）；經900～1000°C煅(duan)(duan)(duan)燒(shao)并(bing)磨(mo)細，可以(yi)得(de)到高溫煅(duan)(duan)(duan)燒(shao)石(shi)(shi)(shi)膏(gao)(gao)(gao)。用這兩種石(shi)(shi)(shi)膏(gao)(gao)(gao)制(zhi)得(de)的(de)制(zhi)品(pin)(pin)，強(qiang)度(du)高于建筑石(shi)(shi)(shi)膏(gao)(gao)(gao)制(zhi)品(pin)(pin)，而(er)且硬(ying)石(shi)(shi)(shi)膏(gao)(gao)(gao)膠結(jie)料(liao)有(you)(you)較(jiao)好的(de)隔熱性(xing)，高溫煅(duan)(duan)(duan)燒(shao)石(shi)(shi)(shi)膏(gao)(gao)(gao)有(you)(you)較(jiao)好的(de)耐(nai)磨(mo)性(xing)和(he)(he)抗(kang)水(shui)性(xing)。
