泡(pao)花(hua)(hua)(hua)(hua)堿(jian)(jian)(jian)(jian)(jian)(jian)生產(chan)工藝可分為(wei)(wei)(wei)干法(fa)和濕法(fa)兩(liang)種，通(tong)常所使用的是干法(fa)生產(chan)固體泡(pao)花(hua)(hua)(hua)(hua)堿(jian)(jian)(jian)(jian)(jian)(jian)，再經(jing)溶(rong)(rong)解轉變成(cheng)所需規格的液(ye)體泡(pao)花(hua)(hua)(hua)(hua)堿(jian)(jian)(jian)(jian)(jian)(jian)，其轉換率為(wei)(wei)(wei)1∶2。5。生產(chan)泡(pao)花(hua)(hua)(hua)(hua)堿(jian)(jian)(jian)(jian)(jian)(jian)的原(yuan)料為(wei)(wei)(wei)石英砂(sha)、純堿(jian)(jian)(jian)(jian)(jian)(jian)，將二者按一(yi)定比(bi)例(li)混合送至反射窯爐中(zhong)，經(jing)高溫煅燒溶(rong)(rong)化(hua)爐水淬(cui)后包裝即為(wei)(wei)(wei)固體泡(pao)花(hua)(hua)(hua)(hua)堿(jian)(jian)(jian)(jian)(jian)(jian)。固體泡(pao)花(hua)(hua)(hua)(hua)堿(jian)(jian)(jian)(jian)(jian)(jian)有利于運輸、貯存。將固體泡(pao)花(hua)(hua)(hua)(hua)堿(jian)(jian)(jian)(jian)(jian)(jian)在一(yi)定溫度、壓力(li)下將其溶(rong)(rong)化(hua)成(cheng)液(ye)體即為(wei)(wei)(wei)液(ye)體泡(pao)花(hua)(hua)(hua)(hua)堿(jian)(jian)(jian)(jian)(jian)(jian)。
化學反應式
化學反應式為(wei)：Na2CO3+SiO2—（高溫）Na2SiO3+CO2↑
制備
石(shi)英砂(sha)、純(chun)堿→混(hun)合→煅燒(shao)→水淬→固(gu)體(ti)泡花(hua)堿→經溶化→液體(ti)泡花(hua)堿
濕法生產
濕(shi)(shi)法(fa)(fa)(fa)生(sheng)(sheng)(sheng)產(chan)(chan)(chan)(chan)(chan)泡(pao)花(hua)堿又分為傳統濕(shi)(shi)法(fa)(fa)(fa)工藝(yi)(yi)和(he)活性(xing)SiO2常壓(ya)生(sheng)(sheng)(sheng)產(chan)(chan)(chan)(chan)(chan)工藝(yi)(yi)兩種。傳統濕(shi)(shi)法(fa)(fa)(fa)生(sheng)(sheng)(sheng)產(chan)(chan)(chan)(chan)(chan)工藝(yi)(yi)傳統濕(shi)(shi)法(fa)(fa)(fa)生(sheng)(sheng)(sheng)產(chan)(chan)(chan)(chan)(chan)泡(pao)花(hua)堿產(chan)(chan)(chan)(chan)(chan)量高，能耗低，勞動(dong)強(qiang)度低，原(yuan)料(liao)(liao)易(yi)得(de)，但該法(fa)(fa)(fa)只能生(sheng)(sheng)(sheng)產(chan)(chan)(chan)(chan)(chan)模(mo)數(shu)小于(yu)2.5的(de)(de)(de)(de)產(chan)(chan)(chan)(chan)(chan)品，其(qi)生(sheng)(sheng)(sheng)產(chan)(chan)(chan)(chan)(chan)原(yuan)理是石英砂在高溫燒堿中(zhong)(zhong)溶解生(sheng)(sheng)(sheng)成(cheng)硅酸(suan)鈉。活性(xing)SiO2常壓(ya)生(sheng)(sheng)(sheng)產(chan)(chan)(chan)(chan)(chan)工藝(yi)(yi)活性(xing)SiO2常壓(ya)生(sheng)(sheng)(sheng)產(chan)(chan)(chan)(chan)(chan)泡(pao)花(hua)堿是在近(jin)幾(ji)年的(de)(de)(de)(de)三廢治(zhi)理過程(cheng)(cheng)中(zhong)(zhong)開發的(de)(de)(de)(de)一(yi)種新工藝(yi)(yi)，目前采用(yong)該法(fa)(fa)(fa)生(sheng)(sheng)(sheng)產(chan)(chan)(chan)(chan)(chan)廠家不(bu)多，該法(fa)(fa)(fa)可生(sheng)(sheng)(sheng)產(chan)(chan)(chan)(chan)(chan)模(mo)數(shu)為2.2～3.7的(de)(de)(de)(de)任何產(chan)(chan)(chan)(chan)(chan)品。其(qi)機理是利用(yong)工業生(sheng)(sheng)(sheng)產(chan)(chan)(chan)(chan)(chan)中(zhong)(zhong)產(chan)(chan)(chan)(chan)(chan)生(sheng)(sheng)(sheng)的(de)(de)(de)(de)副產(chan)(chan)(chan)(chan)(chan)品或(huo)下腳(jiao)料(liao)(liao)中(zhong)(zhong)的(de)(de)(de)(de)活性(xing)SiO2（或(huo)硅膠(jiao)）在常壓(ya)下加熱與(yu)燒堿反應(ying)生(sheng)(sheng)(sheng)成(cheng)硅酸(suan)鈉。反應(ying)方程(cheng)(cheng)式(shi)與(yu)傳統濕(shi)(shi)法(fa)(fa)(fa)工藝(yi)(yi)相同
