家里的(de)(de)(de)銅器上(shang)有黑點擦不掉(diao)(diao)，可以用(yong)鹽(yan)洗掉(diao)(diao)；如(ru)宅(zhai)院(yuan)里雜(za)草長很快，可在(zai)雜(za)草上(shang)灑上(shang)一些工(gong)業(ye)鹽(yan)，批(pi)發工(gong)業(ye)鹽(yan)，3、4天(tian)后就可以見作(zuo)用(yong)；在(zai)機(ji)械工(gong)業(ye)中(zhong)在(zai)鑄造時，鹽(yan)可用(yong)作(zuo)非鐵金屬和合金鑄造中(zhong)型砂的(de)(de)(de)優良粘合劑；在(zai)建材工(gong)業(ye)中(zhong)用(yong)鹽(yan)制(zhi)成的(de)(de)(de)純(chun)堿是(shi)生產玻璃(li)的(de)(de)(de)主要原料；化學工(gong)業(ye)主要產品中(zhong)的(de)(de)(de)鹽(yan)酸、、純(chun)堿、氯化銨、等(deng)主要都是(shi)用(yong)工(gong)業(ye)鹽(yan)為原料生產的(de)(de)(de)。工(gong)業(ye)鹽(yan)是(shi)由地下鹵(lu)水(shui)引入鹽(yan)田，再經日曬干燥，濃縮結(jie)晶，制(zhi)得(de)粗品。

工(gong)(gong)(gong)(gong)(gong)(gong)業(ye)(ye)(ye)(ye)(ye)(ye)鹽(yan)(yan)(yan)八大的(de)(de)用(yong)途：在輕工(gong)(gong)(gong)(gong)(gong)(gong)業(ye)(ye)(ye)(ye)(ye)(ye)中(zhong)在制肥皂(zao)中(zhong)，為(wei)保(bao)持(chi)溶(rong)液有合適的(de)(de)粘度，常常加入鹽(yan)(yan)(yan)；在制革(ge)工(gong)(gong)(gong)(gong)(gong)(gong)業(ye)(ye)(ye)(ye)(ye)(ye)需要大量的(de)(de)皮質(zhi)，原料(liao)皮在貯運過程(cheng)中(zhong)，為(wei)防止或(huo)抑(yi)制微(wei)生物(wu)的(de)(de)侵蝕，需要經(jing)過防腐處理，以免降低皮的(de)(de)質(zhi)量。我們(men)知道工(gong)(gong)(gong)(gong)(gong)(gong)業(ye)(ye)(ye)(ye)(ye)(ye)鹽(yan)(yan)(yan)有個稱號(hao)是(shi)“化(hua)(hua)(hua)學工(gong)(gong)(gong)(gong)(gong)(gong)業(ye)(ye)(ye)(ye)(ye)(ye)”，而化(hua)(hua)(hua)學行(xing)業(ye)(ye)(ye)(ye)(ye)(ye)是(shi)經(jing)濟的(de)(de)基(ji)礎行(xing)業(ye)(ye)(ye)(ye)(ye)(ye)，純堿(jian)也(ye)是(shi)基(ji)本(ben)的(de)(de)化(hua)(hua)(hua)學原料(liao)，而純堿(jian)就是(shi)以工(gong)(gong)(gong)(gong)(gong)(gong)業(ye)(ye)(ye)(ye)(ye)(ye)鹽(yan)(yan)(yan)為(wei)原料(liao)生產(chan)的(de)(de)，工(gong)(gong)(gong)(gong)(gong)(gong)業(ye)(ye)(ye)(ye)(ye)(ye)鹽(yan)(yan)(yan)生產(chan)，每(mei)生產(chan)1噸(dun)純堿(jian)就需要消耗1.2-1.4噸(dun)工(gong)(gong)(gong)(gong)(gong)(gong)業(ye)(ye)(ye)(ye)(ye)(ye)鹽(yan)(yan)(yan)，并且在化(hua)(hua)(hua)學工(gong)(gong)(gong)(gong)(gong)(gong)業(ye)(ye)(ye)(ye)(ye)(ye)生產(chan)中(zhong)差不多每(mei)個步(bu)驟(zou)都需要用(yong)到工(gong)(gong)(gong)(gong)(gong)(gong)業(ye)(ye)(ye)(ye)(ye)(ye)鹽(yan)(yan)(yan)。我們(men)都知道工(gong)(gong)(gong)(gong)(gong)(gong)業(ye)(ye)(ye)(ye)(ye)(ye)鹽(yan)(yan)(yan)廣泛應用(yong)于工(gong)(gong)(gong)(gong)(gong)(gong)業(ye)(ye)(ye)(ye)(ye)(ye)行(xing)業(ye)(ye)(ye)(ye)(ye)(ye)上(shang)(shang)，那肯定有人(ren)會有疑問，工(gong)(gong)(gong)(gong)(gong)(gong)業(ye)(ye)(ye)(ye)(ye)(ye)鹽(yan)(yan)(yan)在工(gong)(gong)(gong)(gong)(gong)(gong)業(ye)(ye)(ye)(ye)(ye)(ye)上(shang)(shang)有什(shen)么作(zuo)用(yong)？到底又是(shi)用(yong)來做什(shen)么的(de)(de)呢(ni)？

副產(chan)鹽(yan)(yan)(yan)(yan)是生產(chan)其它化(hua)工(gong)產(chan)品(pin)的(de)(de)(de)過程中(zhong)生成的(de)(de)(de)氯化(hua)鈉(na)產(chan)品(pin)，雜質不(bu)定，工(gong)業(ye)鹽(yan)(yan)(yan)(yan)，主(zhu)要(yao)用(yong)于水泥助磨劑。產(chan)品(pin)存放(fang)要(yao)防(fang)(fang)止(zhi)(zhi)灰(hui)塵(chen)及(ji)其他(ta)雜物的(de)(de)(de)污(wu)染，防(fang)(fang)止(zhi)(zhi)雨(yu)淋。家(jia)里的(de)(de)(de)掃(sao)帚運用(yong)久了就會(hui)掉(diao)光了，氯化(hua)鈉(na)工(gong)業(ye)鹽(yan)(yan)(yan)(yan)，我們可以將新買的(de)(de)(de)掃(sao)帚浸泡于工(gong)業(ye)鹽(yan)(yan)(yan)(yan)水中(zhong)須(xu)臾(yu)，曬(shai)干今后再運用(yong)就不(bu)會(hui)掉(diao)毛了；吸(xi)(xi)潮(chao)性：工(gong)業(ye)鹽(yan)(yan)(yan)(yan)的(de)(de)(de)表面通常(chang)被一層薄膜狀的(de)(de)(de)飽和鹽(yan)(yan)(yan)(yan)溶(rong)液所包(bao)圍，當這層薄膜溶(rong)液的(de)(de)(de)蒸氣(qi)壓(ya)比空(kong)氣(qi)中(zhong)水蒸氣(qi)分壓(ya)低的(de)(de)(de)時(shi)候，工(gong)業(ye)鹽(yan)(yan)(yan)(yan)就會(hui)吸(xi)(xi)附(fu)空(kong)氣(qi)里面的(de)(de)(de)水分而潮(chao)解(jie)，
