鹽(yan)(yan)，在(zai)(zai)我們(men)(men)生活中很常見，但這里我們(men)(men)介紹的(de)(de)鹽(yan)(yan)卻(que)不是(shi)家中廚房里的(de)(de)鹽(yan)(yan)，而是(shi)工(gong)業(ye)(ye)(ye)(ye)上(shang)常用(yong)到(dao)的(de)(de)鹽(yan)(yan)——工(gong)業(ye)(ye)(ye)(ye)鹽(yan)(yan)。在(zai)(zai)染料工(gong)業(ye)(ye)(ye)(ye)常用(yong)的(de)(de)原料如純(chun)堿是(shi)鹽(yan)(yan)為原料直接(jie)生產(chan)出來的(de)(de)，而且(qie)染料生產(chan)過程中幾(ji)乎每個步驟都要耗用(yong)一定數量的(de)(de)鹽(yan)(yan)；綜上(shang)所述，我們(men)(men)可(ke)以了解到(dao)工(gong)業(ye)(ye)(ye)(ye)鹽(yan)(yan)在(zai)(zai)化學行(xing)業(ye)(ye)(ye)(ye)中的(de)(de)作用(yong)，當然工(gong)業(ye)(ye)(ye)(ye)鹽(yan)(yan)并(bing)不只用(yong)于(yu)化學行(xing)業(ye)(ye)(ye)(ye)上(shang)，工(gong)業(ye)(ye)(ye)(ye)鹽(yan)(yan)廠家批發，還可(ke)以應(ying)用(yong)于(yu)冶金行(xing)業(ye)(ye)(ye)(ye)上(shang)，石油行(xing)業(ye)(ye)(ye)(ye)，印染等行(xing)業(ye)(ye)(ye)(ye)上(shang)。

工(gong)(gong)(gong)(gong)(gong)(gong)(gong)業(ye)(ye)(ye)(ye)(ye)(ye)(ye)(ye)鹽(yan)又叫(jiao)工(gong)(gong)(gong)(gong)(gong)(gong)(gong)業(ye)(ye)(ye)(ye)(ye)(ye)(ye)(ye)用(yong)(yong)鹽(yan)，其主(zhu)要(yao)含量是氯化(hua)鈉(na)。常見的工(gong)(gong)(gong)(gong)(gong)(gong)(gong)業(ye)(ye)(ye)(ye)(ye)(ye)(ye)(ye)鹽(yan)有大(da)顆粒鹽(yan)、小白鹽(yan)、精制鹽(yan)、副產鹽(yan)等。制革工(gong)(gong)(gong)(gong)(gong)(gong)(gong)業(ye)(ye)(ye)(ye)(ye)(ye)(ye)(ye)常用(yong)(yong)的防腐方法，就是鹽(yan)干法；在(zai)(zai)冶金(jin)工(gong)(gong)(gong)(gong)(gong)(gong)(gong)業(ye)(ye)(ye)(ye)(ye)(ye)(ye)(ye)中鹽(yan)在(zai)(zai)冶金(jin)工(gong)(gong)(gong)(gong)(gong)(gong)(gong)業(ye)(ye)(ye)(ye)(ye)(ye)(ye)(ye)中用(yong)(yong)作氯化(hua)焙(bei)燒(shao)劑(ji)和淬火劑(ji)；在(zai)(zai)化(hua)學(xue)(xue)工(gong)(gong)(gong)(gong)(gong)(gong)(gong)業(ye)(ye)(ye)(ye)(ye)(ye)(ye)(ye)中鹽(yan)是化(hua)學(xue)(xue)工(gong)(gong)(gong)(gong)(gong)(gong)(gong)業(ye)(ye)(ye)(ye)(ye)(ye)(ye)(ye)，化(hua)學(xue)(xue)工(gong)(gong)(gong)(gong)(gong)(gong)(gong)業(ye)(ye)(ye)(ye)(ye)(ye)(ye)(ye)是國民經濟的基礎(chu)產業(ye)(ye)(ye)(ye)(ye)(ye)(ye)(ye)。我們(men)知道工(gong)(gong)(gong)(gong)(gong)(gong)(gong)業(ye)(ye)(ye)(ye)(ye)(ye)(ye)(ye)鹽(yan)有個(ge)稱號是“化(hua)學(xue)(xue)工(gong)(gong)(gong)(gong)(gong)(gong)(gong)業(ye)(ye)(ye)(ye)(ye)(ye)(ye)(ye)”，而化(hua)學(xue)(xue)行(xing)業(ye)(ye)(ye)(ye)(ye)(ye)(ye)(ye)是經濟的基礎(chu)行(xing)業(ye)(ye)(ye)(ye)(ye)(ye)(ye)(ye)，純(chun)堿也是基本的化(hua)學(xue)(xue)原料，肥東工(gong)(gong)(gong)(gong)(gong)(gong)(gong)業(ye)(ye)(ye)(ye)(ye)(ye)(ye)(ye)鹽(yan)，而純(chun)堿就是以工(gong)(gong)(gong)(gong)(gong)(gong)(gong)業(ye)(ye)(ye)(ye)(ye)(ye)(ye)(ye)鹽(yan)為原料生產的，每生產1噸(dun)純(chun)堿就需(xu)要(yao)消耗1.2-1.4噸(dun)工(gong)(gong)(gong)(gong)(gong)(gong)(gong)業(ye)(ye)(ye)(ye)(ye)(ye)(ye)(ye)鹽(yan)，并(bing)且在(zai)(zai)化(hua)學(xue)(xue)工(gong)(gong)(gong)(gong)(gong)(gong)(gong)業(ye)(ye)(ye)(ye)(ye)(ye)(ye)(ye)生產中差不多每個(ge)步(bu)驟(zou)都需(xu)要(yao)用(yong)(yong)到(dao)工(gong)(gong)(gong)(gong)(gong)(gong)(gong)業(ye)(ye)(ye)(ye)(ye)(ye)(ye)(ye)鹽(yan)。

工業(ye)(ye)(ye)(ye)鹽(yan)(yan)八(ba)大(da)的(de)(de)(de)用(yong)途：在(zai)輕(qing)工業(ye)(ye)(ye)(ye)中在(zai)制肥皂中，為保(bao)持溶液(ye)有(you)(you)合適的(de)(de)(de)粘度，批發工業(ye)(ye)(ye)(ye)鹽(yan)(yan)，常常加入鹽(yan)(yan)；在(zai)制革工業(ye)(ye)(ye)(ye)需(xu)要大(da)量(liang)的(de)(de)(de)皮(pi)質，原(yuan)料皮(pi)在(zai)貯運過(guo)(guo)程(cheng)中，為防止或抑制微生(sheng)(sheng)物的(de)(de)(de)侵蝕，需(xu)要經(jing)過(guo)(guo)防腐處理，以(yi)免降低皮(pi)的(de)(de)(de)質量(liang)。我(wo)們知(zhi)道(dao)工業(ye)(ye)(ye)(ye)鹽(yan)(yan)有(you)(you)個稱號是“化(hua)學工業(ye)(ye)(ye)(ye)”，而化(hua)學行業(ye)(ye)(ye)(ye)是經(jing)濟的(de)(de)(de)基(ji)礎(chu)行業(ye)(ye)(ye)(ye)，純堿也是基(ji)本(ben)的(de)(de)(de)化(hua)學原(yuan)料，而純堿就是以(yi)工業(ye)(ye)(ye)(ye)鹽(yan)(yan)為原(yuan)料生(sheng)(sheng)產的(de)(de)(de)，工業(ye)(ye)(ye)(ye)鹽(yan)(yan)多(duo)少錢一斤，每生(sheng)(sheng)產1噸純堿就需(xu)要消耗1.2-1.4噸工業(ye)(ye)(ye)(ye)鹽(yan)(yan)，并且在(zai)化(hua)學工業(ye)(ye)(ye)(ye)生(sheng)(sheng)產中差不多(duo)每個步驟都(dou)需(xu)要用(yong)到(dao)工業(ye)(ye)(ye)(ye)鹽(yan)(yan)。我(wo)們都(dou)知(zhi)道(dao)工業(ye)(ye)(ye)(ye)鹽(yan)(yan)廣泛(fan)應用(yong)于工業(ye)(ye)(ye)(ye)行業(ye)(ye)(ye)(ye)上，那肯定有(you)(you)人會(hui)有(you)(you)疑問，工業(ye)(ye)(ye)(ye)鹽(yan)(yan)在(zai)工業(ye)(ye)(ye)(ye)上有(you)(you)什么作(zuo)用(yong)？到(dao)底又是用(yong)來做什么的(de)(de)(de)呢？
