制(zhi)革工(gong)(gong)業(ye)(ye)(ye)常用(yong)的(de)(de)防腐方(fang)法，就是(shi)鹽(yan)(yan)干法；在(zai)冶金(jin)(jin)工(gong)(gong)業(ye)(ye)(ye)中鹽(yan)(yan)在(zai)冶金(jin)(jin)工(gong)(gong)業(ye)(ye)(ye)中用(yong)作氯化焙燒劑和(he)淬火劑；在(zai)化學工(gong)(gong)業(ye)(ye)(ye)中鹽(yan)(yan)是(shi)化學工(gong)(gong)業(ye)(ye)(ye)，化學工(gong)(gong)業(ye)(ye)(ye)是(shi)國民經濟的(de)(de)基礎產業(ye)(ye)(ye)。工(gong)(gong)業(ye)(ye)(ye)鹽(yan)(yan)在(zai)工(gong)(gong)業(ye)(ye)(ye)上的(de)(de)用(yong)途很廣，批(pi)發(fa)工(gong)(gong)業(ye)(ye)(ye)鹽(yan)(yan)，它是(shi)外觀無色的(de)(de)立方(fang)結晶(jing)或細小(xiao)(xiao)結晶(jing)粉(fen)末，易溶于水。用(yong)地(di)下鹽(yan)(yan)水和(he)井鹽(yan)(yan)為原料時，通過三(san)效或四(si)效蒸(zheng)發(fa)濃縮，析出結晶(jing)，離心分離制(zhi)得工(gong)(gong)業(ye)(ye)(ye)鹽(yan)(yan)。小(xiao)(xiao)白(bai)鹽(yan)(yan)顆粒一般比工(gong)(gong)業(ye)(ye)(ye)鹽(yan)(yan)小(xiao)(xiao)，工(gong)(gong)業(ye)(ye)(ye)鹽(yan)(yan)批(pi)發(fa)，主(zhu)要(yao)用(yong)于養殖行業(ye)(ye)(ye)中。精制(zhi)鹽(yan)(yan)形狀接近粉(fen)末，顏色白(bai)，流動性好，可(ke)以(yi)長時間(jian)不(bu)結塊(kuai)，黃山(shan)工(gong)(gong)業(ye)(ye)(ye)鹽(yan)(yan)，主(zhu)要(yao)用(yong)作或洗衣液添加劑。

大(da)顆粒(li)鹽(yan)又叫海(hai)鹽(yan)、粗鹽(yan)，或者(zhe)日曬海(hai)鹽(yan)。顆粒(li)大(da)（顆粒(li)大(da)小(xiao)可根據客戶的(de)要(yao)求研磨(mo)）。大(da)顆粒(li)鹽(yan)主(zhu)要(yao)用于(yu)熱敷和鍋(guo)爐水(shui)的(de)處(chu)理。此(ci)外(wai)，還用于(yu)肥皂制造、陶瓷、玻璃生(sheng)(sheng)產、日用化(hua)(hua)(hua)工(gong)、石油鉆(zhan)探、鉆(zhan)井(jing)工(gong)作液(ye)(ye)、完井(jing)液(ye)(ye)、石油化(hua)(hua)(hua)工(gong)脫(tuo)水(shui)液(ye)(ye)、建(jian)筑行(xing)(xing)業(ye)(ye)早強劑(ji)、生(sheng)(sheng)產涂料的(de)凝固劑(ji)、橡(xiang)膠行(xing)(xing)業(ye)(ye)乳膠凝結(jie)劑(ji)、造紙工(gong)業(ye)(ye)添(tian)加劑(ji)及(ji)廢紙張(zhang)脫(tuo)墨(mo)、化(hua)(hua)(hua)學工(gong)業(ye)(ye)的(de)無機(ji)化(hua)(hua)(hua)工(gong)原(yuan)料及(ji)硫酸根脫(tuo)除劑(ji)，我(wo)們知道化(hua)(hua)(hua)學行(xing)(xing)業(ye)(ye)上(shang)多種化(hua)(hua)(hua)學產品都是以工(gong)業(ye)(ye)鹽(yan)為原(yuan)料生(sheng)(sheng)產的(de)，不(bu)僅如(ru)此(ci)，工(gong)業(ye)(ye)鹽(yan)在其他(ta)行(xing)(xing)業(ye)(ye)上(shang)也(ye)都有(you)作用，那下面我(wo)們就一起來探討一下工(gong)業(ye)(ye)鹽(yan)在化(hua)(hua)(hua)學工(gong)業(ye)(ye)上(shang)的(de)作用。

制革(ge)工(gong)(gong)(gong)(gong)業(ye)(ye)常用(yong)的(de)(de)(de)防(fang)腐方法，就(jiu)(jiu)是(shi)鹽(yan)(yan)(yan)干法；在冶(ye)金(jin)工(gong)(gong)(gong)(gong)業(ye)(ye)中(zhong)(zhong)鹽(yan)(yan)(yan)在冶(ye)金(jin)工(gong)(gong)(gong)(gong)業(ye)(ye)中(zhong)(zhong)用(yong)作氯化(hua)(hua)(hua)(hua)(hua)焙燒劑和淬火(huo)劑；在化(hua)(hua)(hua)(hua)(hua)學(xue)(xue)工(gong)(gong)(gong)(gong)業(ye)(ye)中(zhong)(zhong)鹽(yan)(yan)(yan)是(shi)化(hua)(hua)(hua)(hua)(hua)學(xue)(xue)工(gong)(gong)(gong)(gong)業(ye)(ye)，化(hua)(hua)(hua)(hua)(hua)學(xue)(xue)工(gong)(gong)(gong)(gong)業(ye)(ye)是(shi)國民經濟(ji)的(de)(de)(de)基(ji)礎產(chan)業(ye)(ye)。化(hua)(hua)(hua)(hua)(hua)學(xue)(xue)工(gong)(gong)(gong)(gong)業(ye)(ye)主要產(chan)品中(zhong)(zhong)的(de)(de)(de)鹽(yan)(yan)(yan)酸、、純堿(jian)(jian)、氯化(hua)(hua)(hua)(hua)(hua)銨(an)、等主要都是(shi)用(yong)工(gong)(gong)(gong)(gong)業(ye)(ye)鹽(yan)(yan)(yan)為(wei)原料(liao)生產(chan)的(de)(de)(de)。工(gong)(gong)(gong)(gong)業(ye)(ye)鹽(yan)(yan)(yan)是(shi)由地下鹵(lu)水引入鹽(yan)(yan)(yan)田，再(zai)經日曬(shai)干燥，濃(nong)縮結晶，生產(chan)工(gong)(gong)(gong)(gong)業(ye)(ye)鹽(yan)(yan)(yan)，制得粗品。我們知道工(gong)(gong)(gong)(gong)業(ye)(ye)鹽(yan)(yan)(yan)有(you)個(ge)稱號是(shi)“化(hua)(hua)(hua)(hua)(hua)學(xue)(xue)工(gong)(gong)(gong)(gong)業(ye)(ye)”，而化(hua)(hua)(hua)(hua)(hua)學(xue)(xue)行業(ye)(ye)是(shi)經濟(ji)的(de)(de)(de)基(ji)礎行業(ye)(ye)，純堿(jian)(jian)也是(shi)基(ji)本的(de)(de)(de)化(hua)(hua)(hua)(hua)(hua)學(xue)(xue)原料(liao)，而純堿(jian)(jian)就(jiu)(jiu)是(shi)以(yi)工(gong)(gong)(gong)(gong)業(ye)(ye)鹽(yan)(yan)(yan)為(wei)原料(liao)生產(chan)的(de)(de)(de)，每(mei)生產(chan)1噸純堿(jian)(jian)就(jiu)(jiu)需要消耗1.2-1.4噸工(gong)(gong)(gong)(gong)業(ye)(ye)鹽(yan)(yan)(yan)，并且在化(hua)(hua)(hua)(hua)(hua)學(xue)(xue)工(gong)(gong)(gong)(gong)業(ye)(ye)生產(chan)中(zhong)(zhong)差不多每(mei)個(ge)步驟都需要用(yong)到工(gong)(gong)(gong)(gong)業(ye)(ye)鹽(yan)(yan)(yan)。
