工業鹽又稱氯化鈉，廣泛應用于工業中。它是化工的基本原料之一，被稱為化工之母。鹽酸、燒堿、純堿、氯化銨、氯氣等主要基礎化工產品主要以工業鹽為原(yuan)料(liao)生(sheng)產(chan)(chan)。有(you)機(ji)合成工(gong)業(ye)需要大量的(de)氯化(hua)(hua)鈉(na)。此(ci)外，還用于肥皂制造、陶(tao)瓷、玻璃生(sheng)產(chan)(chan)、日常化(hua)(hua)工(gong)、石油(you)鉆(zhan)探、鉆(zhan)井工(gong)作液(ye)、完井液(ye)、石化(hua)(hua)脫水液(ye)、建筑行業(ye)早(zao)強(qiang)劑、生(sheng)產(chan)(chan)涂料(liao)凝固(gu)(gu)劑、橡膠行業(ye)乳(ru)膠凝固(gu)(gu)劑、造紙行業(ye)添加劑及廢紙脫墨(mo)、化(hua)(hua)工(gong)無機(ji)化(hua)(hua)工(gong)原(yuan)料(liao)及硫(liu)酸根脫墨(mo)劑、褐藻(zao)酸鈉(na)凝固(gu)(gu)劑、防治小麥、蘋果、卷(juan)心菜等腐爛(lan)食(shi)品防腐劑、制備金屬鈉(na)等鈉(na)化(hua)(hua)合物、鋼熱(re)處理介質等。鹽也廣泛應用于水處理、公路除(chu)雪、制冷等領域。

     工業鹽基本介紹：
     鹽(yan)(yan)(yan)在工(gong)(gong)(gong)(gong)業上應用(yong)廣泛，是化(hua)(hua)工(gong)(gong)(gong)(gong)的基本原料之一，被稱(cheng)為化(hua)(hua)工(gong)(gong)(gong)(gong)之母。鹽(yan)(yan)(yan)酸、燒堿(jian)、純堿(jian)、氯化(hua)(hua)銨、氯氣等(deng)主要基礎化(hua)(hua)工(gong)(gong)(gong)(gong)產(chan)(chan)(chan)品主要以工(gong)(gong)(gong)(gong)業鹽(yan)(yan)(yan)為原料生產(chan)(chan)(chan)。有機合成工(gong)(gong)(gong)(gong)業需要大(da)量的氯化(hua)(hua)鈉。工(gong)(gong)(gong)(gong)業鹽(yan)(yan)(yan)價(jia)格，此外，還用(yong)于(yu)(yu)肥(fei)皂(zao)制(zhi)造(zao)、陶瓷、玻璃(li)生產(chan)(chan)(chan)、日常化(hua)(hua)工(gong)(gong)(gong)(gong)、石油鉆探、鉆井(jing)工(gong)(gong)(gong)(gong)作液、井(jing)液、石化(hua)(hua)脫水(shui)、建筑業早期(qi)強化(hua)(hua)劑(ji)、生產(chan)(chan)(chan)涂料凝固劑(ji)、橡膠工(gong)(gong)(gong)(gong)業乳(ru)膠凝固劑(ji)、造(zao)紙(zhi)工(gong)(gong)(gong)(gong)業添(tian)加劑(ji)、廢紙(zhi)脫墨、化(hua)(hua)工(gong)(gong)(gong)(gong)無機化(hua)(hua)工(gong)(gong)(gong)(gong)原料、硫酸根除劑(ji)、褐藻(zao)酸鈉凝固劑(ji)、防(fang)(fang)治小(xiao)麥(mai)、蘋果、卷心(xin)菜等(deng)腐爛(lan)食品防(fang)(fang)腐劑(ji)、制(zhi)備金屬鈉等(deng)鈉化(hua)(hua)合物、鋼熱處理介質(zhi)等(deng)。鹽(yan)(yan)(yan)也廣泛應用(yong)于(yu)(yu)水(shui)處理、公路除雪(xue)、制(zhi)冷等(deng)領域。
      氯化鈉(na)仍然是工業鹽的(de)重要成分，但它含有大量(liang)對人(ren)體(ti)有害的(de)物質(zhi)，如(ru)亞(ya)硝酸(suan)鉀、亞(ya)硝酸(suan)鈉(na)、碳酸(suan)鈉(na)、鉛和砷。
      機(ji)械工業中工業鹽的用途：
   ;   (1)高溫(wen)下，工(gong)業鹽使鑄件芯變軟，防止鑄件熱裂紋；
      (2)工業鹽可作(zuo)為非鐵金屬和合(he)金鑄造中型砂(sha)的(de)優(you)良粘合(he)劑；
   ;  (3)電鍍(du)前(qian)強(qiang)酸(suan)洗黑金(jin)屬(shu)、銅、銅合金(jin)需要工(gong)業鹽(yan)；
     (4)鋼制機械零(ling)件或工具在(zai)熱(re)處(chu)理時(shi)，常用的加熱(re)設備是鹽浴(yu)爐。
