工業副(fu)產石膏簡介

工(gong)業副產(chan)(chan)石(shi)(shi)膏是指(zhi)在化(hua)工(gong)生產(chan)(chan)過程中(zhong)所(suo)得的以CaSO4·2H2O或CaSO4·H2O為主要成(cheng)分的副產(chan)(chan)品,稱為工(gong)業副產(chan)(chan)石(shi)(shi)膏。目前排放量(liang)較(jiao)大的有脫硫石(shi)(shi)膏、磷(lin)石(shi)(shi)膏、氟石(shi)(shi)膏、鹽石(shi)(shi)膏等。工(gong)業副產(chan)(chan)石(shi)(shi)膏含有超過10%的游離水(shui)。我公司結合國內(nei)外化(hua)學石(shi)(shi)膏制備建筑(zhu)石(shi)(shi)膏粉的成(cheng)功(gong)經驗，采用二步法(fa)生產(chan)(chan)工(gong)藝制備建筑(zhu)石(shi)(shi)膏粉。
