泡(pao)(pao)花(hua)堿(jian)(jian)(jian)生產工藝可(ke)分為(wei)(wei)干法和濕法兩(liang)種(zhong)，通常所使用的是干法生產固體(ti)泡(pao)(pao)花(hua)堿(jian)(jian)(jian)，再經(jing)溶(rong)解轉(zhuan)變成(cheng)所需規(gui)格的液(ye)體(ti)泡(pao)(pao)花(hua)堿(jian)(jian)(jian)，其轉(zhuan)換率為(wei)(wei)1∶2。5。生產泡(pao)(pao)花(hua)堿(jian)(jian)(jian)的原料為(wei)(wei)石英砂、純堿(jian)(jian)(jian)，將(jiang)二者按一定比(bi)例(li)混(hun)合送至反射窯爐中，經(jing)高溫(wen)煅(duan)燒(shao)溶(rong)化(hua)爐水淬后(hou)包裝即為(wei)(wei)固體(ti)泡(pao)(pao)花(hua)堿(jian)(jian)(jian)。固體(ti)泡(pao)(pao)花(hua)堿(jian)(jian)(jian)有利于運輸、貯存(cun)。將(jiang)固體(ti)泡(pao)(pao)花(hua)堿(jian)(jian)(jian)在(zai)一定溫(wen)度、壓力下(xia)將(jiang)其溶(rong)化(hua)成(cheng)液(ye)體(ti)即為(wei)(wei)液(ye)體(ti)泡(pao)(pao)花(hua)堿(jian)(jian)(jian)。
化學反應式
化學反應式為：Na2CO3+SiO2—（高溫）Na2SiO3+CO2↑
制備
石英(ying)砂、純堿(jian)→混合→煅燒→水(shui)淬→固體泡花堿(jian)→經溶化→液(ye)體泡花堿(jian)
濕法生產
濕(shi)法(fa)(fa)生(sheng)(sheng)(sheng)(sheng)產(chan)泡花(hua)堿(jian)(jian)又分(fen)為傳(chuan)統(tong)濕(shi)法(fa)(fa)工(gong)(gong)(gong)(gong)藝(yi)(yi)和(he)活性(xing)SiO2常壓(ya)生(sheng)(sheng)(sheng)(sheng)產(chan)工(gong)(gong)(gong)(gong)藝(yi)(yi)兩種。傳(chuan)統(tong)濕(shi)法(fa)(fa)生(sheng)(sheng)(sheng)(sheng)產(chan)工(gong)(gong)(gong)(gong)藝(yi)(yi)傳(chuan)統(tong)濕(shi)法(fa)(fa)生(sheng)(sheng)(sheng)(sheng)產(chan)泡花(hua)堿(jian)(jian)產(chan)量高(gao)，能耗低(di)，勞(lao)動強度低(di)，原料易得(de)，但該(gai)法(fa)(fa)只能生(sheng)(sheng)(sheng)(sheng)產(chan)模數小于2.5的產(chan)品(pin)，其(qi)生(sheng)(sheng)(sheng)(sheng)產(chan)原理是(shi)(shi)石英砂(sha)在高(gao)溫燒堿(jian)(jian)中溶解生(sheng)(sheng)(sheng)(sheng)成硅(gui)酸鈉。活性(xing)SiO2常壓(ya)生(sheng)(sheng)(sheng)(sheng)產(chan)工(gong)(gong)(gong)(gong)藝(yi)(yi)活性(xing)SiO2常壓(ya)生(sheng)(sheng)(sheng)(sheng)產(chan)泡花(hua)堿(jian)(jian)是(shi)(shi)在近幾年的三廢治理過程中開發的一種新工(gong)(gong)(gong)(gong)藝(yi)(yi)，目前采(cai)用(yong)該(gai)法(fa)(fa)生(sheng)(sheng)(sheng)(sheng)產(chan)廠家不多，該(gai)法(fa)(fa)可生(sheng)(sheng)(sheng)(sheng)產(chan)模數為2.2～3.7的任何產(chan)品(pin)。其(qi)機理是(shi)(shi)利(li)用(yong)工(gong)(gong)(gong)(gong)業生(sheng)(sheng)(sheng)(sheng)產(chan)中產(chan)生(sheng)(sheng)(sheng)(sheng)的副產(chan)品(pin)或下(xia)腳料中的活性(xing)SiO2（或硅(gui)膠）在常壓(ya)下(xia)加(jia)熱與(yu)(yu)燒堿(jian)(jian)反(fan)應(ying)生(sheng)(sheng)(sheng)(sheng)成硅(gui)酸鈉。反(fan)應(ying)方程式與(yu)(yu)傳(chuan)統(tong)濕(shi)法(fa)(fa)工(gong)(gong)(gong)(gong)藝(yi)(yi)相同
