泡(pao)(pao)(pao)花(hua)堿(jian)生(sheng)產工藝可(ke)分(fen)為干法(fa)和濕(shi)法(fa)兩種(zhong)，通(tong)常所使用的(de)(de)是干法(fa)生(sheng)產固(gu)體(ti)泡(pao)(pao)(pao)花(hua)堿(jian)，再經(jing)溶(rong)解轉變成所需規格(ge)的(de)(de)液(ye)(ye)體(ti)泡(pao)(pao)(pao)花(hua)堿(jian)，其(qi)轉換(huan)率為1∶2。5。生(sheng)產泡(pao)(pao)(pao)花(hua)堿(jian)的(de)(de)原(yuan)料為石英砂、純堿(jian)，將(jiang)(jiang)二者按一定比(bi)例(li)混(hun)合送至反射窯爐(lu)中，經(jing)高溫煅燒溶(rong)化爐(lu)水淬(cui)后包裝即為固(gu)體(ti)泡(pao)(pao)(pao)花(hua)堿(jian)。固(gu)體(ti)泡(pao)(pao)(pao)花(hua)堿(jian)有利(li)于運輸、貯存(cun)。將(jiang)(jiang)固(gu)體(ti)泡(pao)(pao)(pao)花(hua)堿(jian)在一定溫度(du)、壓力下將(jiang)(jiang)其(qi)溶(rong)化成液(ye)(ye)體(ti)即為液(ye)(ye)體(ti)泡(pao)(pao)(pao)花(hua)堿(jian)。
化學反應式
化(hua)學反應式為：Na2CO3+SiO2—（高(gao)溫(wen)）Na2SiO3+CO2↑
制備
石英砂(sha)、純(chun)堿→混合→煅燒→水淬→固體泡花堿→經溶化→液體泡花堿
濕法生產
