在機械工(gong)(gong)業(ye)中在鑄造時，鹽(yan)(yan)可(ke)用作非鐵金屬和(he)合金鑄造中型砂的優良粘合劑；在建材(cai)工(gong)(gong)業(ye)中用鹽(yan)(yan)制成的純堿(jian)是生產玻璃的主要(yao)原料(liao)；用鹽(yan)(yan)水洗藤、竹器，會變的很(hen)(hen)經用；工(gong)(gong)業(ye)鹽(yan)(yan)在工(gong)(gong)業(ye)上的用途(tu)很(hen)(hen)廣，它(ta)是外觀無色的立(li)方結(jie)(jie)晶(jing)或(huo)(huo)細小結(jie)(jie)晶(jing)粉末，工(gong)(gong)業(ye)鹽(yan)(yan)銷售，易(yi)溶于水。用地下(xia)鹽(yan)(yan)水和(he)井鹽(yan)(yan)為原料(liao)時，合肥(fei)工(gong)(gong)業(ye)鹽(yan)(yan)，通過三效或(huo)(huo)四效蒸發濃縮，析出結(jie)(jie)晶(jing)，離心分離制得工(gong)(gong)業(ye)鹽(yan)(yan)。

化學工(gong)業(ye)(ye)主(zhu)要產(chan)(chan)品(pin)中(zhong)的(de)鹽(yan)(yan)(yan)(yan)(yan)酸、、純堿(jian)、氯化銨、等(deng)主(zhu)要都是用(yong)工(gong)業(ye)(ye)鹽(yan)(yan)(yan)(yan)(yan)為原料生(sheng)產(chan)(chan)的(de)。工(gong)業(ye)(ye)鹽(yan)(yan)(yan)(yan)(yan)是由地下鹵水引入鹽(yan)(yan)(yan)(yan)(yan)田，再經日曬干燥，濃縮結晶，制(zhi)得粗品(pin)。綜上所述，精致工(gong)業(ye)(ye)鹽(yan)(yan)(yan)(yan)(yan)，我們(men)可以(yi)了解到(dao)工(gong)業(ye)(ye)鹽(yan)(yan)(yan)(yan)(yan)在化學行業(ye)(ye)中(zhong)的(de)作用(yong)，當然(ran)工(gong)業(ye)(ye)鹽(yan)(yan)(yan)(yan)(yan)并不只用(yong)于(yu)化學行業(ye)(ye)上，工(gong)業(ye)(ye)鹽(yan)(yan)(yan)(yan)(yan)生(sheng)產(chan)(chan)，還可以(yi)應用(yong)于(yu)冶(ye)金(jin)行業(ye)(ye)上，石油行業(ye)(ye)，印染等(deng)行業(ye)(ye)上。工(gong)業(ye)(ye)鹽(yan)(yan)(yan)(yan)(yan)又叫(jiao)工(gong)業(ye)(ye)用(yong)鹽(yan)(yan)(yan)(yan)(yan)，其主(zhu)要含量是氯化鈉。常見(jian)的(de)工(gong)業(ye)(ye)鹽(yan)(yan)(yan)(yan)(yan)有大顆粒鹽(yan)(yan)(yan)(yan)(yan)、小白鹽(yan)(yan)(yan)(yan)(yan)、精制(zhi)鹽(yan)(yan)(yan)(yan)(yan)、副產(chan)(chan)鹽(yan)(yan)(yan)(yan)(yan)等(deng)。

工業(ye)(ye)鹽(yan)又叫工業(ye)(ye)用(yong)鹽(yan)，其主(zhu)要含(han)量是氯化鈉(na)。常見的(de)(de)工業(ye)(ye)鹽(yan)有大(da)顆粒鹽(yan)、小白鹽(yan)、精制鹽(yan)、副產鹽(yan)等(deng)。油井鉆探過程(cheng)中，為(wei)保護巖鹽(yan)層巖心的(de)(de)完整性，需在(zai)泥(ni)漿中添加鹽(yan)作穩定(ding)劑(ji)；在(zai)工業(ye)(ye)化時(shi)代(dai)之前，人們所說的(de)(de)鹽(yan)，特指生活(huo)中調味(wei)用(yong)的(de)(de)，而不是現在(zai)化學科學中的(de)(de)“鹽(yan)”。在(zai)機械工業(ye)(ye)中在(zai)鑄造(zao)時(shi)，鹽(yan)可(ke)用(yong)作非鐵(tie)金屬和合金鑄造(zao)中型砂的(de)(de)優良(liang)粘合劑(ji)；在(zai)建材(cai)工業(ye)(ye)中用(yong)鹽(yan)制成的(de)(de)純堿是生產玻璃的(de)(de)主(zhu)要原料；
