天(tian)然石膏簡介

天然二水石(shi)(shi)膏(gao)(gao)(gao)（CaSO4·2H2O）又(you)稱為(wei)生石(shi)(shi)膏(gao)(gao)(gao)，經過煅燒、磨細可得β型(xing)半水石(shi)(shi)膏(gao)(gao)(gao)（CaSO4·?H2O），即(ji)建筑石(shi)(shi)膏(gao)(gao)(gao)，又(you)稱 熟(shu)石(shi)(shi)膏(gao)(gao)(gao) 、 灰泥 。石(shi)(shi)膏(gao)(gao)(gao)礦以沉積(ji)(ji)型(xing)礦床為(wei)主，儲量占全國90%以上，后生型(xing)及熱液交代型(xing)石(shi)(shi)膏(gao)(gao)(gao)礦不很重要(yao)。石(shi)(shi)膏(gao)(gao)(gao)礦在各地質時代均有(you)產出，以早白堊紀(ji)和第(di)三紀(ji)沉積(ji)(ji)型(xing)石(shi)(shi)膏(gao)(gao)(gao)礦為(wei)最重要(yao)。

天然石(shi)(shi)(shi)(shi)(shi)膏(gao)中用(yong)(yong)(yong)(yong)途最(zui)廣的(de)(de)(de)是二水石(shi)(shi)(shi)(shi)(shi)膏(gao)，其(qi)有(you)效(xiao)成分(fen)為二水硫(liu)酸(suan)鈣(gai)，一般根(gen)據礦(kuang)石(shi)(shi)(shi)(shi)(shi)中二水硫(liu)酸(suan)鈣(gai)含量對(dui)石(shi)(shi)(shi)(shi)(shi)膏(gao)進行(xing)等(deng)級劃分(fen)。石(shi)(shi)(shi)(shi)(shi)膏(gao)應用(yong)(yong)(yong)(yong)領(ling)域較(jiao)寬(kuan)，產品種類也較(jiao)多(duo)(duo)，不同(tong)的(de)(de)(de)用(yong)(yong)(yong)(yong)途對(dui)石(shi)(shi)(shi)(shi)(shi)膏(gao)原(yuan)料(liao)的(de)(de)(de)質量有(you)著(zhu)不同(tong)的(de)(de)(de)要(yao)求，高(gao)品位石(shi)(shi)(shi)(shi)(shi)膏(gao)多(duo)(duo)被用(yong)(yong)(yong)(yong)于(yu)特種石(shi)(shi)(shi)(shi)(shi)膏(gao)產品的(de)(de)(de)生產原(yuan)料(liao)，如食用(yong)(yong)(yong)(yong)、醫用(yong)(yong)(yong)(yong)、藝術品、模型和化工(gong)填料(liao)等(deng)；二水硫(liu)酸(suan)鈣(gai)含量低(di)于(yu)60%的(de)(de)(de)石(shi)(shi)(shi)(shi)(shi)膏(gao)礦(kuang)則很少得到(dao)應用(yong)(yong)(yong)(yong)；高(gao)于(yu)60%的(de)(de)(de)石(shi)(shi)(shi)(shi)(shi)膏(gao)礦(kuang)石(shi)(shi)(shi)(shi)(shi)，則根(gen)據其(qi)含量的(de)(de)(de)不同(tong)，被用(yong)(yong)(yong)(yong)于(yu)建(jian)材、建(jian)筑(zhu)等(deng)各個領(ling)域。
