工業副產(chan)石膏簡介

工(gong)(gong)業(ye)副(fu)產石(shi)(shi)膏(gao)是指在化工(gong)(gong)生(sheng)(sheng)產過程中所得的以CaSO4·2H2O或CaSO4·H2O為主要成分的副(fu)產品,稱為工(gong)(gong)業(ye)副(fu)產石(shi)(shi)膏(gao)。目前(qian)排放量(liang)較大的有脫硫石(shi)(shi)膏(gao)、磷石(shi)(shi)膏(gao)、氟(fu)石(shi)(shi)膏(gao)、鹽石(shi)(shi)膏(gao)等。工(gong)(gong)業(ye)副(fu)產石(shi)(shi)膏(gao)含(han)有超過10%的游離水(shui)。我公司(si)結合(he)國(guo)內外化學石(shi)(shi)膏(gao)制(zhi)備(bei)建(jian)筑(zhu)石(shi)(shi)膏(gao)粉(fen)(fen)的成功經驗，采用二步法生(sheng)(sheng)產工(gong)(gong)藝(yi)制(zhi)備(bei)建(jian)筑(zhu)石(shi)(shi)膏(gao)粉(fen)(fen)。
