天然石膏簡介

天然(ran)二水(shui)石膏(gao)(gao)(gao)(gao)（CaSO4·2H2O）又(you)稱(cheng)為生石膏(gao)(gao)(gao)(gao)，經過煅(duan)燒、磨細可得β型(xing)半水(shui)石膏(gao)(gao)(gao)(gao)（CaSO4·?H2O），即建筑石膏(gao)(gao)(gao)(gao)，又(you)稱(cheng) 熟石膏(gao)(gao)(gao)(gao) 、 灰泥(ni) 。石膏(gao)(gao)(gao)(gao)礦以(yi)沉積型(xing)礦床為主(zhu)，儲量占全國(guo)90%以(yi)上，后生型(xing)及熱液交代型(xing)石膏(gao)(gao)(gao)(gao)礦不很重(zhong)要。石膏(gao)(gao)(gao)(gao)礦在各地質時代均有產出(chu)，以(yi)早白堊紀和(he)第三(san)紀沉積型(xing)石膏(gao)(gao)(gao)(gao)礦為最重(zhong)要。

天然(ran)石(shi)(shi)(shi)(shi)(shi)(shi)膏(gao)(gao)中用(yong)(yong)(yong)(yong)途(tu)(tu)最廣的(de)是二(er)水石(shi)(shi)(shi)(shi)(shi)(shi)膏(gao)(gao)，其有效成(cheng)分(fen)為二(er)水硫(liu)酸(suan)鈣，一般根據礦石(shi)(shi)(shi)(shi)(shi)(shi)中二(er)水硫(liu)酸(suan)鈣含量(liang)(liang)(liang)對石(shi)(shi)(shi)(shi)(shi)(shi)膏(gao)(gao)進行(xing)等(deng)(deng)級劃分(fen)。石(shi)(shi)(shi)(shi)(shi)(shi)膏(gao)(gao)應用(yong)(yong)(yong)(yong)領(ling)域(yu)較(jiao)寬，產品(pin)種(zhong)類(lei)也較(jiao)多，不(bu)(bu)同的(de)用(yong)(yong)(yong)(yong)途(tu)(tu)對石(shi)(shi)(shi)(shi)(shi)(shi)膏(gao)(gao)原料(liao)的(de)質量(liang)(liang)(liang)有著不(bu)(bu)同的(de)要求(qiu)，高品(pin)位石(shi)(shi)(shi)(shi)(shi)(shi)膏(gao)(gao)多被(bei)用(yong)(yong)(yong)(yong)于(yu)(yu)特(te)種(zhong)石(shi)(shi)(shi)(shi)(shi)(shi)膏(gao)(gao)產品(pin)的(de)生產原料(liao)，如食用(yong)(yong)(yong)(yong)、醫用(yong)(yong)(yong)(yong)、藝術品(pin)、模型和化工填料(liao)等(deng)(deng)；二(er)水硫(liu)酸(suan)鈣含量(liang)(liang)(liang)低于(yu)(yu)60%的(de)石(shi)(shi)(shi)(shi)(shi)(shi)膏(gao)(gao)礦則很少得到應用(yong)(yong)(yong)(yong)；高于(yu)(yu)60%的(de)石(shi)(shi)(shi)(shi)(shi)(shi)膏(gao)(gao)礦石(shi)(shi)(shi)(shi)(shi)(shi)，則根據其含量(liang)(liang)(liang)的(de)不(bu)(bu)同，被(bei)用(yong)(yong)(yong)(yong)于(yu)(yu)建材、建筑等(deng)(deng)各個領(ling)域(yu)。
