要(yao)理解(jie)(jie)工業(ye)(ye)鹽(yan)(yan)加工設備工業(ye)(ye)鹽(yan)(yan)為何能融雪，先要(yao)搞知道它是(shi)什(shen)麼，其(qi)次要(yao)成分(fen)爲Nacl，它溶于水(shui)，并且容易吸(xi)潮(chao)，細(xi)心察看家里常常放鹽(yan)(yan)的(de)中(zhong)央(yang)總是(shi)濕濕的(de)，久(jiu)久(jiu)不(bu)干，緣由(you)就是(shi)鹽(yan)(yan)的(de)吸(xi)潮(chao)性，工業(ye)(ye)鹽(yan)(yan)加工設備加工，它外表(biao)被一(yi)層薄(bo)膜狀(zhuang)的(de)飽和(he)鹽(yan)(yan)溶液解(jie)(jie)圍，當這層薄(bo)膜溶液的(de)蒸氣(qi)壓低于空(kong)氣(qi)中(zhong)水(shui)蒸氣(qi)分(fen)壓時，食(shi)鹽(yan)(yan)就吸(xi)附(fu)空(kong)氣(qi)中(zhong)的(de)水(shui)分(fen)而潮(chao)解(jie)(jie)；反(fan)之，當高于空(kong)氣(qi)中(zhong)水(shui)蒸氣(qi)分(fen)壓時則出現(xian)枯燥形(xing)態。當然，這只是(shi)在食(shi)鹽(yan)(yan)被表(biao)露在空(kong)氣(qi)中(zhong)才(cai)有的(de)景象，密閉在包裝(zhuang)袋(dai)中(zhong)與四周(zhou)空(kong)氣(qi)隔絕的(de)食(shi)鹽(yan)(yan)是(shi)不(bu)會潮(chao)解(jie)(jie)的(de)。

工(gong)(gong)(gong)業(ye)鹽(yan)加(jia)工(gong)(gong)(gong)設備工(gong)(gong)(gong)業(ye)鹽(yan)在工(gong)(gong)(gong)業(ye)上的(de)用(yong)途很廣，是化學(xue)工(gong)(gong)(gong)業(ye)的(de)基本原(yuan)料之一，被稱為(wei)“化學(xue)工(gong)(gong)(gong)業(ye)”。基本化學(xue)工(gong)(gong)(gong)業(ye)主要(yao)產品中的(de)鹽(yan)酸、、純堿(jian)、氯化銨、等主要(yao)是用(yong)工(gong)(gong)(gong)業(ye)鹽(yan)為(wei)原(yuan)料生產的(de)。

工(gong)(gong)(gong)業(ye)(ye)鹽(yan)(yan)(yan) 指的(de)是(shi)原(yuan)鹽(yan)(yan)(yan)，原(yuan)鹽(yan)(yan)(yan)有(you)湖鹽(yan)(yan)(yan)、井鹽(yan)(yan)(yan)和海(hai)鹽(yan)(yan)(yan)之分，其中因(yin)為海(hai)鹽(yan)(yan)(yan)中的(de)海(hai)水溶入了多(duo)種元素，所以海(hai)鹽(yan)(yan)(yan)的(de)工(gong)(gong)(gong)業(ye)(ye)價值相對要(yao)高些，食用價值要(yao)低些。工(gong)(gong)(gong)業(ye)(ye)鹽(yan)(yan)(yan)是(shi)白色(se)(se)無味或者(zhe)是(shi)灰白色(se)(se)有(you)色(se)(se)，無色(se)(se)結晶性粉末(mo)，熔點240℃（分解）。不溶于(yu)水，乙醇和一般的(de)，微溶于(yu)水，工(gong)(gong)(gong)業(ye)(ye)鹽(yan)(yan)(yan)加工(gong)(gong)(gong)設備(bei)，但易溶于(yu)和氨水，工(gong)(gong)(gong)業(ye)(ye)鹽(yan)(yan)(yan)加工(gong)(gong)(gong)設備(bei)生產(chan)線，溶于(yu)100℃沸水160。其堿鹽(yan)(yan)(yan)可(ke)溶于(yu)水，一般用四(si)鈉鹽(yan)(yan)(yan)代替EDTA。

工業鹽(yan)加工設備工業鹽(yan)的使用注意事項(xiang)：

1、工(gong)業(ye)(ye)鹽的(de)主(zhu)要成分雖然也(ye)是氯化鈉，但不(bu)(bu)像食(shi)用(yong)鹽一(yi)樣經過高純度(du)提取，可能會不(bu)(bu)同(tong)程度(du)地含有一(yi)些(xie)雜質，甚(shen)至可能存(cun)在重(zhong)金屬超(chao)標的(de)情況，人類食(shi)用(yong)的(de)話(hua)可能會導致(zhi)或者慢性危(wei)害(hai)。工(gong)業(ye)(ye)鹽不(bu)(bu)能食(shi)用(yong)，食(shi)融雪工(gong)業(ye)(ye)用(yong)鹽后果(guo)嚴重(zhong)，不(bu)(bu)能用(yong)作菜品制(zhi)作。

2、帶包裝的產(chan)品應在包裝上注明產(chan)品名稱、規格、商(shang)標、等級(ji)、生產(chan)單位以及本標準(zhun)編號。

3、運(yun)輸(shu)時應有遮(zhe)蓋物，不應與能(neng)導致產品污染的貨物混裝。

4、產品(pin)存放要防(fang)止灰塵及(ji)其他雜物(wu)的污染(ran)，防(fang)止雨淋。
