天然石膏簡介

天然二(er)水(shui)石(shi)(shi)(shi)膏(gao)(gao)(gao)(gao)(gao)（CaSO4·2H2O）又(you)稱為(wei)生石(shi)(shi)(shi)膏(gao)(gao)(gao)(gao)(gao)，經過煅(duan)燒(shao)、磨(mo)細可得(de)β型半水(shui)石(shi)(shi)(shi)膏(gao)(gao)(gao)(gao)(gao)（CaSO4·?H2O），即(ji)建筑石(shi)(shi)(shi)膏(gao)(gao)(gao)(gao)(gao)，又(you)稱 熟石(shi)(shi)(shi)膏(gao)(gao)(gao)(gao)(gao) 、 灰泥 。石(shi)(shi)(shi)膏(gao)(gao)(gao)(gao)(gao)礦以沉積型礦床為(wei)主，儲(chu)量占全國90%以上，后生型及熱液交代型石(shi)(shi)(shi)膏(gao)(gao)(gao)(gao)(gao)礦不(bu)很重(zhong)要。石(shi)(shi)(shi)膏(gao)(gao)(gao)(gao)(gao)礦在各地質時代均有產出，以早白堊紀和第三紀沉積型石(shi)(shi)(shi)膏(gao)(gao)(gao)(gao)(gao)礦為(wei)最重(zhong)要。

天然石(shi)(shi)(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)中(zhong)用(yong)(yong)途最(zui)廣的(de)是二水石(shi)(shi)(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)，其有(you)效成分為二水硫(liu)酸鈣，一般根(gen)據礦(kuang)石(shi)(shi)(shi)(shi)(shi)(shi)中(zhong)二水硫(liu)酸鈣含(han)(han)量對石(shi)(shi)(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)進行等(deng)級劃分。石(shi)(shi)(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)應用(yong)(yong)領域較寬，產品(pin)種類也較多(duo)，不同(tong)的(de)用(yong)(yong)途對石(shi)(shi)(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)原料的(de)質量有(you)著不同(tong)的(de)要求，高品(pin)位石(shi)(shi)(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)多(duo)被用(yong)(yong)于特種石(shi)(shi)(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)產品(pin)的(de)生產原料，如(ru)食(shi)用(yong)(yong)、醫用(yong)(yong)、藝術品(pin)、模(mo)型和化工(gong)填料等(deng)；二水硫(liu)酸鈣含(han)(han)量低于60%的(de)石(shi)(shi)(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)礦(kuang)則很少(shao)得(de)到應用(yong)(yong)；高于60%的(de)石(shi)(shi)(shi)(shi)(shi)(shi)膏(gao)(gao)(gao)礦(kuang)石(shi)(shi)(shi)(shi)(shi)(shi)，則根(gen)據其含(han)(han)量的(de)不同(tong)，被用(yong)(yong)于建材、建筑等(deng)各個領域。
