工(gong)(gong)業(ye)鹽(yan)(yan)(yan)(yan)也被稱(cheng)為(wei)“氯(lv)(lv)化鈉”。工(gong)(gong)業(ye)鹽(yan)(yan)(yan)(yan)在工(gong)(gong)業(ye)中被廣泛使(shi)用。它是化學工(gong)(gong)業(ye)中Z基本的(de)原(yuan)材料之(zhi)(zhi)一，被稱(cheng)為(wei)“化學工(gong)(gong)業(ye)之(zhi)(zhi)母”。基礎化工(gong)(gong)主要產品(pin)中的(de)鹽(yan)(yan)(yan)(yan)酸、燒堿(jian)、純堿(jian)、氯(lv)(lv)化銨(an)和氯(lv)(lv)主要以工(gong)(gong)業(ye)鹽(yan)(yan)(yan)(yan)為(wei)原(yuan)料生產

工(gong)(gong)(gong)業(ye)(ye)鹽(yan)一般用(yong)于制皂(zao)、陶(tao)瓷(ci)、玻(bo)璃(li)生產、日(ri)用(yong)化(hua)(hua)工(gong)(gong)(gong)、石油(you)鉆井、鉆井液、完井液、，石油(you)化(hua)(hua)工(gong)(gong)(gong)脫(tuo)水液、建筑行業(ye)(ye)的(de)早強劑(ji)、涂料生產用(yong)混凝(ning)劑(ji)、橡膠行業(ye)(ye)的(de)乳膠混凝(ning)劑(ji)、造紙行業(ye)(ye)和(he)廢紙脫(tuo)墨添加(jia)劑(ji)、化(hua)(hua)工(gong)(gong)(gong)行業(ye)(ye)的(de)無機化(hua)(hua)工(gong)(gong)(gong)原料和(he)硫酸鹽(yan)去除劑(ji)、，海(hai)藻(zao)酸鈉(na)凝(ning)固劑(ji)可防(fang)(fang)止和(he)控制小麥、蘋果、卷(juan)心菜(cai)等食品防(fang)(fang)腐劑(ji)的(de)腐爛，制備(bei)金屬鈉(na)和(he)其(qi)他鈉(na)化(hua)(hua)合(he)物，鋼熱(re)處理介質等。鹽(yan)還廣泛(fan)應用(yong)于水處理、公路除雪、，制冷和(he)其(qi)他方(fang)面

[工業鹽的危害]

除了(le)工業(ye)鹽(yan)不含(han)碘(dian)之外(wai)，很大的危害是(shi)它含(han)有過(guo)量(liang)(liang)的亞硝酸(suan)鈉(na)。過(guo)量(liang)(liang)攝入(ru)亞硝酸(suan)鈉(na)后，人們會(hui)出現全(quan)身無(wu)力(li)、頭(tou)痛、頭(tou)暈、惡心、嘔吐、腹瀉(xie)、胸悶、呼吸困難等癥(zheng)狀。在(zai)嚴重(zhong)情況下(xia)，血壓會(hui)下(xia)降、昏迷和(he)死亡。不僅(jin)直接食(shi)(shi)用(yong)工業(ye)鹽(yan)會(hui)導(dao)致中毒，而且食(shi)(shi)用(yong)用(yong)工業(ye)鹽(yan)腌制(zhi)的鴨(ya)蛋和(he)咸魚(yu)也會(hui)導(dao)致中毒。氯(lv)(lv)化鈉(na)的化學式(shi)(shi)(shi)為NaCl，其(qi)式(shi)(shi)(shi)量(liang)(liang)為58.44，由(you)氯(lv)(lv)離子和(he)鈉(na)離子組成(cheng)。除了(le)氯(lv)(lv)化鈉(na)，工業(ye)鹽(yan)還含(han)有過(guo)量(liang)(liang)的亞硝酸(suan)鈉(na)。其(qi)化學式(shi)(shi)(shi)為NaNO2，式(shi)(shi)(shi)量(liang)(liang)為69.00，由(you)亞硝酸(suan)鹽(yan)離子和(he)鈉(na)離子

 2組成。性質：食鹽(yan)的性質相(xiang)對穩定，水(shui)溶液為中(zhong)性。亞硝(xiao)酸(suan)鈉在干燥條件(jian)下(xia)相(xiang)對穩定，但(dan)它能緩慢吸收氧(yang)氣并氧(yang)化為硝(xiao)酸(suan)鈉。水(shui)溶液呈(cheng)堿(jian)性

 3。外觀：均(jun)為(wei)白色。在特殊情況下(xia)，食鹽也(ye)可(ke)能顯(xian)(xian)(xian)示黃(huang)色或淺(qian)藍色，亞硝(xiao)酸鈉也(ye)可(ke)能顯(xian)(xian)(xian)示淺(qian)黃(huang)色。它們都是晶體，在顯(xian)(xian)(xian)微鏡下(xia)幾何形狀有一定差異，但用肉眼無(wu)法分辨。溶解性：亞硝(xiao)酸鈉和食鹽極易(yi)溶于水，易(yi)潮解，無(wu)異味

 5。味(wei)道(dao)：亞硝酸鈉微咸，鹽咸，難以通(tong)過味(wei)道(dao)來區分。
