寧夏工業鹽在(zai)染(ran)料(liao)工(gong)(gong)(gong)業(ye)中(zhong)的(de)(de)(de)應用(yong)(yong)染(ran)料(liao)工(gong)(gong)(gong)業(ye)常用(yong)(yong)的(de)(de)(de)原料(liao)如燒堿(jian)、純堿(jian)是(shi)鹽(yan)為(wei)原料(liao)直接(jie)生產(chan)出來的(de)(de)(de)，鹽(yan)酸、硫化(hua)(hua)鈉、保險(xian)粉等是(shi)鹽(yan)經深加工(gong)(gong)(gong)制得的(de)(de)(de)化(hua)(hua)工(gong)(gong)(gong)產(chan)品；此外(wai)，還(huan)直接(jie)耗(hao)用(yong)(yong)大量(liang)的(de)(de)(de)鹽(yan)。所以說(shuo)，染(ran)料(liao)工(gong)(gong)(gong)業(ye)是(shi)除(chu)了氯堿(jian)工(gong)(gong)(gong)業(ye)以外(wai)，與鹽(yan)業(ye)關系非(fei)常密切的(de)(de)(de)行業(ye)之一。而(er)且染(ran)料(liao)生產(chan)過程中(zhong)幾乎每個(ge)步驟都(dou)要(yao)耗(hao)用(yong)(yong)一定數量(liang)的(de)(de)(de)鹽(yan)。在(zai)冶(ye)金(jin)工(gong)(gong)(gong)業(ye)中(zhong)的(de)(de)(de)應用(yong)(yong)工(gong)(gong)(gong)業(ye)鹽(yan)在(zai)冶(ye)金(jin)工(gong)(gong)(gong)業(ye)中(zhong)用(yong)(yong)作氯化(hua)(hua)焙(bei)燒劑(ji)和淬火劑(ji)，也作處理金(jin)屬礦石(shi)的(de)(de)(de)脫硫劑(ji)和澄清劑(ji)。鋼制品和鋼軋(ya)制品浸(jin)入(ru)食鹽(yan)溶液，可(ke)使(shi)其表面硬化(hua)(hua)并除(chu)去氧化(hua)(hua)膜(mo)。帶鋼及不(bu)銹鋼的(de)(de)(de)酸洗，煉鋁、電解解金(jin)屬鈉等的(de)(de)(de)助焙(bei)劑(ji)都(dou)要(yao)用(yong)(yong)到鹽(yan)化(hua)(hua)工(gong)(gong)(gong)產(chan)品，以及冶(ye)煉中(zhong)的(de)(de)(de)耐(nai)火材(cai)料(liao)等都(dou)需要(yao)鹽(yan)化(hua)(hua)工(gong)(gong)(gong)產(chan)品。

在工(gong)業化(hua)的時(shi)代(dai)中，人(ren)們所(suo)認(ren)識的鹽不是現代(dai)化(hua)學(xue)科學(xue)中所(suo)說的工(gong)業鹽，所(suo)以鹽還分為(wei)可食(shi)用鹽和(he)不可食(shi)用的工(gong)業鹽，只有(you)在正確認(ren)識到這(zhe)一(yi)點之后(hou)，才可保(bao)證不會因(yin)為(wei)誤食(shi)有(you)毒(du)(du)鹽類(lei)而引發群體(ti)中了毒(du)(du)事(shi)件(jian)。

工業鹽的用途

用于肥皂制造、陶瓷、玻璃(li)出產(chan)(chan)(chan)、日(ri)用化(hua)工(gong)、石油(you)鉆探、鉆井工(gong)作液(ye)、完井液(ye)、石油(you)化(hua)工(gong)脫水液(ye)、建筑行業(ye)早強劑(ji)(ji)、出產(chan)(chan)(chan)涂料的(de)凝固劑(ji)(ji)、橡膠(jiao)行業(ye)乳膠(jiao)凝聚劑(ji)(ji)、造紙(zhi)產(chan)(chan)(chan)業(ye)添加劑(ji)(ji)及廢(fei)紙(zhi)張(zhang)脫墨、化(hua)學產(chan)(chan)(chan)業(ye)的(de)無機(ji)化(hua)工(gong)原料及硫酸(suan)根(gen)脫除劑(ji)(ji)等。

工業鹽水有著再生(sheng)離(li)子交換(huan)樹(shu)脂的(de)(de)主(zhu)要功(gong)能。水中的(de)(de)不良離(li)子主(zhu)要由鈣(gai)(gai)、鎂(mei)(mei)離(li)子組成，一般(ban)去除(chu)鈣(gai)(gai)鎂(mei)(mei)離(li)子的(de)(de)方(fang)法(fa)是(shi)，想辦法(fa)讓水通過裝有陽離(li)子交換(huan)樹(shu)脂的(de)(de)軟水裝置設備(bei)，將(jiang)水中的(de)(de)鈣(gai)(gai)離(li)子、鎂(mei)(mei)離(li)子置換(huan)出來，隨著樹(shu)脂內鈣(gai)(gai)離(li)子、鎂(mei)(mei)離(li)子的(de)(de)增(zeng)加，然(ran)后(hou)用樹(shu)脂去除(chu)鈣(gai)(gai)離(li)子、鎂(mei)(mei)離(li)子的(de)(de)效能逐漸降低。當樹(shu)脂吸收(shou)一定(ding)量的(de)(de)工業鹽中的(de)(de)鈣(gai)(gai)鎂(mei)(mei)離(li)子時，就(jiu)必須進(jin)行再生(sheng)創(chuang)造，而樹(shu)脂的(de)(de)再生(sheng)過程就(jiu)是(shi)用工業鹽水沖洗樹(shu)脂層，把樹(shu)脂上(shang)的(de)(de)鈣(gai)(gai)鎂(mei)(mei)離(li)子置換(huan)出來，然(ran)后(hou)樹(shu)脂就(jiu)恢復原有功(gong)能。
