天然石(shi)膏簡介

天然二水石(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)（CaSO4·2H2O）又(you)稱(cheng)為生石(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)，經過煅(duan)燒、磨(mo)細(xi)可得β型(xing)(xing)半水石(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)（CaSO4·?H2O），即建(jian)筑石(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)，又(you)稱(cheng) 熟(shu)石(shi)(shi)(shi)(shi)膏(gao)(gao)(gao) 、 灰(hui)泥 。石(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)礦(kuang)以沉積型(xing)(xing)礦(kuang)床為主，儲(chu)量占全國90%以上，后生型(xing)(xing)及熱(re)液交代(dai)型(xing)(xing)石(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)礦(kuang)不很重要(yao)。石(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)礦(kuang)在(zai)各(ge)地質時代(dai)均有產出(chu)，以早白堊紀(ji)和第(di)三紀(ji)沉積型(xing)(xing)石(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)礦(kuang)為最重要(yao)。

天(tian)然石(shi)(shi)(shi)(shi)膏(gao)中用(yong)(yong)途最廣的(de)是二水石(shi)(shi)(shi)(shi)膏(gao)，其(qi)有(you)效成分為(wei)二水硫(liu)(liu)酸(suan)鈣，一般根(gen)據礦(kuang)石(shi)(shi)(shi)(shi)中二水硫(liu)(liu)酸(suan)鈣含(han)量對石(shi)(shi)(shi)(shi)膏(gao)進(jin)行(xing)等(deng)級(ji)劃分。石(shi)(shi)(shi)(shi)膏(gao)應用(yong)(yong)領(ling)域較寬，產(chan)品(pin)種(zhong)類也(ye)較多(duo)，不(bu)同的(de)用(yong)(yong)途對石(shi)(shi)(shi)(shi)膏(gao)原(yuan)料(liao)的(de)質(zhi)量有(you)著(zhu)不(bu)同的(de)要求，高品(pin)位石(shi)(shi)(shi)(shi)膏(gao)多(duo)被用(yong)(yong)于特種(zhong)石(shi)(shi)(shi)(shi)膏(gao)產(chan)品(pin)的(de)生產(chan)原(yuan)料(liao)，如食用(yong)(yong)、醫用(yong)(yong)、藝術品(pin)、模型和化(hua)工填料(liao)等(deng)；二水硫(liu)(liu)酸(suan)鈣含(han)量低于60%的(de)石(shi)(shi)(shi)(shi)膏(gao)礦(kuang)則很(hen)少得到應用(yong)(yong)；高于60%的(de)石(shi)(shi)(shi)(shi)膏(gao)礦(kuang)石(shi)(shi)(shi)(shi)，則根(gen)據其(qi)含(han)量的(de)不(bu)同，被用(yong)(yong)于建(jian)(jian)材、建(jian)(jian)筑等(deng)各個領(ling)域。
