天然石(shi)膏簡介

天(tian)然(ran)二水石(shi)(shi)膏(gao)(gao)（CaSO4·2H2O）又(you)稱(cheng)為(wei)生石(shi)(shi)膏(gao)(gao)，經過(guo)煅(duan)燒、磨(mo)細可得(de)β型(xing)(xing)(xing)半水石(shi)(shi)膏(gao)(gao)（CaSO4·?H2O），即建筑石(shi)(shi)膏(gao)(gao)，又(you)稱(cheng) 熟(shu)石(shi)(shi)膏(gao)(gao) 、 灰(hui)泥(ni) 。石(shi)(shi)膏(gao)(gao)礦(kuang)以(yi)沉(chen)積型(xing)(xing)(xing)礦(kuang)床為(wei)主，儲(chu)量(liang)占全國90%以(yi)上，后生型(xing)(xing)(xing)及熱液交代(dai)型(xing)(xing)(xing)石(shi)(shi)膏(gao)(gao)礦(kuang)不很重要。石(shi)(shi)膏(gao)(gao)礦(kuang)在(zai)各地質(zhi)時代(dai)均有產出，以(yi)早(zao)白堊紀和第三(san)紀沉(chen)積型(xing)(xing)(xing)石(shi)(shi)膏(gao)(gao)礦(kuang)為(wei)最重要。

天(tian)然石(shi)(shi)(shi)膏(gao)(gao)(gao)(gao)中用(yong)(yong)(yong)(yong)途最廣的(de)是二(er)水(shui)石(shi)(shi)(shi)膏(gao)(gao)(gao)(gao)，其有效成分為二(er)水(shui)硫酸(suan)鈣(gai)，一(yi)般根據礦(kuang)石(shi)(shi)(shi)中二(er)水(shui)硫酸(suan)鈣(gai)含量對石(shi)(shi)(shi)膏(gao)(gao)(gao)(gao)進行等(deng)級劃分。石(shi)(shi)(shi)膏(gao)(gao)(gao)(gao)應用(yong)(yong)(yong)(yong)領域較寬，產(chan)品種類也較多，不(bu)同(tong)的(de)用(yong)(yong)(yong)(yong)途對石(shi)(shi)(shi)膏(gao)(gao)(gao)(gao)原料(liao)的(de)質(zhi)量有著不(bu)同(tong)的(de)要求，高品位(wei)石(shi)(shi)(shi)膏(gao)(gao)(gao)(gao)多被用(yong)(yong)(yong)(yong)于(yu)(yu)特種石(shi)(shi)(shi)膏(gao)(gao)(gao)(gao)產(chan)品的(de)生產(chan)原料(liao)，如食(shi)用(yong)(yong)(yong)(yong)、醫用(yong)(yong)(yong)(yong)、藝術品、模型(xing)和化工填料(liao)等(deng)；二(er)水(shui)硫酸(suan)鈣(gai)含量低于(yu)(yu)60%的(de)石(shi)(shi)(shi)膏(gao)(gao)(gao)(gao)礦(kuang)則(ze)很少得到應用(yong)(yong)(yong)(yong)；高于(yu)(yu)60%的(de)石(shi)(shi)(shi)膏(gao)(gao)(gao)(gao)礦(kuang)石(shi)(shi)(shi)，則(ze)根據其含量的(de)不(bu)同(tong)，被用(yong)(yong)(yong)(yong)于(yu)(yu)建材、建筑等(deng)各個領域。
