天然石(shi)膏簡介

天然(ran)二水(shui)石(shi)(shi)膏(gao)(gao)（CaSO4·2H2O）又(you)稱為生石(shi)(shi)膏(gao)(gao)，經(jing)過煅(duan)燒、磨細可得β型(xing)半水(shui)石(shi)(shi)膏(gao)(gao)（CaSO4·?H2O），即建筑石(shi)(shi)膏(gao)(gao)，又(you)稱 熟石(shi)(shi)膏(gao)(gao) 、 灰泥 。石(shi)(shi)膏(gao)(gao)礦以沉積(ji)型(xing)礦床為主，儲(chu)量占(zhan)全國90%以上，后生型(xing)及(ji)熱液交代型(xing)石(shi)(shi)膏(gao)(gao)礦不很重要。石(shi)(shi)膏(gao)(gao)礦在各地質時代均(jun)有產出，以早白堊紀和第三紀沉積(ji)型(xing)石(shi)(shi)膏(gao)(gao)礦為最重要。

天然石(shi)(shi)膏(gao)(gao)(gao)(gao)中(zhong)用(yong)(yong)(yong)(yong)途最(zui)廣的(de)是二(er)(er)水(shui)石(shi)(shi)膏(gao)(gao)(gao)(gao)，其有效成分為二(er)(er)水(shui)硫酸鈣(gai)，一(yi)般根據礦(kuang)石(shi)(shi)中(zhong)二(er)(er)水(shui)硫酸鈣(gai)含(han)量對石(shi)(shi)膏(gao)(gao)(gao)(gao)進行(xing)等(deng)級劃(hua)分。石(shi)(shi)膏(gao)(gao)(gao)(gao)應用(yong)(yong)(yong)(yong)領域較寬(kuan)，產(chan)品(pin)種類也(ye)較多，不(bu)同(tong)的(de)用(yong)(yong)(yong)(yong)途對石(shi)(shi)膏(gao)(gao)(gao)(gao)原料的(de)質(zhi)量有著不(bu)同(tong)的(de)要(yao)求，高品(pin)位石(shi)(shi)膏(gao)(gao)(gao)(gao)多被(bei)用(yong)(yong)(yong)(yong)于(yu)特(te)種石(shi)(shi)膏(gao)(gao)(gao)(gao)產(chan)品(pin)的(de)生產(chan)原料，如(ru)食用(yong)(yong)(yong)(yong)、醫(yi)用(yong)(yong)(yong)(yong)、藝術品(pin)、模(mo)型和化工填(tian)料等(deng)；二(er)(er)水(shui)硫酸鈣(gai)含(han)量低于(yu)60%的(de)石(shi)(shi)膏(gao)(gao)(gao)(gao)礦(kuang)則很少得到應用(yong)(yong)(yong)(yong)；高于(yu)60%的(de)石(shi)(shi)膏(gao)(gao)(gao)(gao)礦(kuang)石(shi)(shi)，則根據其含(han)量的(de)不(bu)同(tong)，被(bei)用(yong)(yong)(yong)(yong)于(yu)建材、建筑等(deng)各個領域。
