解決方(fang)案(an)
天然二水石(shi)(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)（CaSO4·2H2O）又稱為(wei)生(sheng)石(shi)(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)，經(jing)過煅(duan)(duan)燒(shao)、磨(mo)細(xi)可得(de)β型半(ban)水石(shi)(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)（CaSO4·1/2H2O），即建筑(zhu)石(shi)(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)，又稱熟(shu)石(shi)(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)、灰(hui)泥(ni)。若煅(duan)(duan)燒(shao)溫(wen)度為(wei)190 °C可得(de)模型石(shi)(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)，其(qi)細(xi)度和(he)白(bai)度均比建筑(zhu)石(shi)(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)高(gao)。若將生(sheng)石(shi)(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)在(zai)400-500 °C或高(gao)于(yu)800 °C下煅(duan)(duan)燒(shao)，即得(de)地板石(shi)(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)，其(qi)凝結、硬化(hua)較(jiao)慢，但(dan)硬化(hua)后強度、耐(nai)磨(mo)性和(he)耐(nai)水性均較(jiao)普(pu)通建筑(zhu)石(shi)(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)為(wei)好。通常為(wei)白(bai)色(se)(se)、無色(se)(se)，無色(se)(se)透明晶體稱為(wei)透石(shi)(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)，有時因含(han)雜質(zhi)而成灰(hui)、淺(qian)黃(huang)、淺(qian)褐等色(se)(se)。
石(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)(gao)(gao)屬單(dan)斜(xie)晶(jing)系，解(jie)理(li)度很高，容易裂開(kai)成薄片。將石(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)(gao)(gao)加(jia)熱100～200°C，失去部分結(jie)(jie)(jie)(jie)晶(jing)水(shui)(shui)，可(ke)得(de)到(dao)(dao)(dao)半(ban)(ban)水(shui)(shui)石(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)(gao)(gao)。 α型半(ban)(ban)水(shui)(shui)石(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)(gao)(gao)結(jie)(jie)(jie)(jie)晶(jing)良好、堅(jian)實； β型半(ban)(ban)水(shui)(shui)石(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)(gao)(gao)是片狀(zhuang)并有(you)裂紋的(de)(de)晶(jing)體，結(jie)(jie)(jie)(jie)晶(jing)很細，比(bi)表面積比(bi) α型半(ban)(ban)水(shui)(shui)石(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)(gao)(gao)大(da)得(de)多。生(sheng)產石(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)(gao)(gao)制品(pin)時， α型半(ban)(ban)水(shui)(shui)石(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)(gao)(gao)比(bi) β型需水(shui)(shui)量少(shao)(shao)，制品(pin)有(you)較高的(de)(de)密實度和(he)強(qiang)(qiang)(qiang)度。通常用蒸壓釜(fu)在飽和(he)蒸汽介質中蒸煉而(er)成的(de)(de)是 α型半(ban)(ban)水(shui)(shui)石(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)(gao)(gao)，也稱(cheng)高強(qiang)(qiang)(qiang)石(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)(gao)(gao)；用炒鍋或回(hui)轉窯敞開(kai)裝置煅(duan)煉而(er)成的(de)(de)是β型半(ban)(ban)水(shui)(shui)石(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)(gao)(gao)，亦即建筑(zhu)石(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)(gao)(gao)。半(ban)(ban)水(shui)(shui)石(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)(gao)(gao)與水(shui)(shui)拌和(he)的(de)(de)漿體重新(xin)形成二(er)水(shui)(shui)石(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)(gao)(gao)、在干燥過(guo)程中迅速凝(ning)(ning)結(jie)(jie)(jie)(jie)硬(ying)化(hua)而(er)獲得(de)強(qiang)(qiang)(qiang)度，但遇水(shui)(shui)則軟化(hua)。石(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)(gao)(gao)是生(sheng)產石(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)(gao)(gao)膠凝(ning)(ning)材料和(he)石(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)(gao)(gao)建筑(zhu)制品(pin)的(de)(de)主要原料，也是硅酸鹽水(shui)(shui)泥的(de)(de)緩凝(ning)(ning)劑(ji)。石(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)(gao)(gao)經600～800°C煅(duan)燒(shao)后，加(jia)入少(shao)(shao)量石(shi)(shi)(shi)(shi)灰等催化(hua)劑(ji)共同磨(mo)細，可(ke)以得(de)到(dao)(dao)(dao)硬(ying)石(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)(gao)(gao)膠結(jie)(jie)(jie)(jie)料（也稱(cheng)金氏膠結(jie)(jie)(jie)(jie)料）；經900～1000°C煅(duan)燒(shao)并磨(mo)細，可(ke)以得(de)到(dao)(dao)(dao)高溫煅(duan)燒(shao)石(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)(gao)(gao)。用這兩種(zhong)石(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)(gao)(gao)制得(de)的(de)(de)制品(pin)，強(qiang)(qiang)(qiang)度高于建筑(zhu)石(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)(gao)(gao)制品(pin)，而(er)且硬(ying)石(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)(gao)(gao)膠結(jie)(jie)(jie)(jie)料有(you)較好的(de)(de)隔熱性，高溫煅(duan)燒(shao)石(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)(gao)(gao)有(you)較好的(de)(de)耐磨(mo)性和(he)抗水(shui)(shui)性。
