工業鹽是什么？

工業鹽是化工*基本的原料之一，被稱為“化工之母”。廣泛應用于兩堿化工、精細化工、印染、農藥、玻璃、合成橡膠、制冷劑、粘合劑、成像管、陶瓷制品、皮革加工、造紙等行業。
誤食工業鹽有什么危害？
工(gong)(gong)業(ye)鹽(yan)除了不(bu)含(han)碘外，*大的(de)(de)危害是含(han)有過量(liang)的(de)(de)亞(ya)硝酸鈉。過量(liang)食(shi)用亞(ya)硝酸鹽(yan)中毒后，表現為全(quan)身(shen)無(wu)力(li)、頭(tou)(tou)痛、頭(tou)(tou)暈、惡心、嘔吐(tu)、腹(fu)瀉(xie)、胸(xiong)部急(ji)迫感、呼吸困(kun)難，檢查皮膚粘膜(mo)明(ming)顯發紺；嚴重(zhong)者(zhe)，血壓下(xia)降、昏迷(mi)、死亡。不(bu)僅直接食(shi)用會引起中毒，用工(gong)(gong)業(ye)鹽(yan)腌制食(shi)品甚至鴨蛋也(ye)會引起中毒。由于亞(ya)硝酸鹽(yan)和鹽(yan)表面難以(yi)區分，一些(xie)非(fei)法經營者(zhe)只(zhi)是盈利(li)，為了賺取高利(li)潤，從化工(gong)(gong)廠家購買極低的(de)(de)廢鹽(yan)，腳鹽(yan)，銷往(wang)鹽(yan)市場，容(rong)易造成巨大的(de)(de)食(shi)品安全(quan)風(feng)險。
工(gong)業(ye)(ye)鹽(yan)作為食(shi)(shi)用鹽(yan)對(dui)我們的健康有什么(me)危(wei)害(hai)？由于工(gong)業(ye)(ye)鹽(yan)和食(shi)(shi)用鹽(yan)的主要成分是(shi)(shi)氯化(hua)鈉，味道差別不大，烹飪中作為調味品的鹽(yan)量(liang)有限，工(gong)業(ye)(ye)鹽(yan)對(dui)人(ren)(ren)體的危(wei)害(hai)主要是(shi)(shi)一個慢(man)性過程，如(ru)鉛、砷(shen)、汞、鎘、亞硝酸鹽(yan)等雜質，重金屬(shu)的長期積(ji)累可能(neng)導致頭暈、皮膚(fu)病、心肌(ji)損傷、神經炎、多器官功能(neng)障礙、肌(ji)肉(rou)痙攣、腹痛、嘔(ou)吐(tu)、骨痛、腎炎，甚至致癌和致畸。此(ci)外(wai)，大量(liang)的亞硝酸鹽(yan)會(hui)在進入人(ren)(ren)體后將(jiang)攜帶氧氣的低鐵血紅(hong)蛋白(bai)轉(zhuan)化(hua)為高鐵血紅(hong)蛋白(bai)。高鐵血紅(hong)蛋白(bai)一旦(dan)遇到氧氣，就會(hui)牢固結(jie)合，不易分離。這(zhe)樣，人(ren)(ren)體的全(quan)身組織就會(hui)缺氧。
工(gong)業(ye)鹽(yan)用(yong)(yong)作冶金(jin)工(gong)業(ye)中(zhong)的氯化(hua)焙(bei)燒劑(ji)和(he)淬火劑(ji)，也用(yong)(yong)作處理金(jin)屬礦石的脫硫劑(ji)和(he)澄(cheng)清劑(ji)。將鹽(yan)溶液(ye)浸泡在鋼制品(pin)和(he)鋼軋制品(pin)中(zhong)，可使(shi)其表(biao)面硬化(hua)并(bing)去(qu)除(chu)氧化(hua)膜。鹽(yan)化(hua)工(gong)產品(pin)用(yong)(yong)于酸洗、煉(lian)鋁、電解金(jin)屬鈉等。以及冶煉(lian)中(zhong)的耐火材料，都需要鹽(yan)化(hua)工(gong)產品(pin)。
為(wei)了使(shi)工業(ye)鹽(yan)更*地用于冶金行業(ye)，在(zai)采購時也要注意其質(zhi)量(liang)控制，使(shi)其在(zai)行業(ye)領域(yu)發揮更*的(de)作用。
