工業(ye)鹽(yan)，是(shi)化(hua)(hua)學工業(ye)的最基本原料之一(yi)，主(zhu)要成分有氯(lv)化(hua)(hua)鈉(na)(na)、亞硝酸鈉(na)(na)等，被稱(cheng)為“化(hua)(hua)學工業(ye)之母(mu)”。基本化(hua)(hua)學工業(ye)主(zhu)要產品中的鹽(yan)酸、燒堿、純(chun)堿、氯(lv)化(hua)(hua)銨、氯(lv)氣等主(zhu)要是(shi)用工業(ye)鹽(yan)為原料生產的。

　　基本化學(xue)工(gong)(gong)(gong)業主要產品中的(de)(de)鹽酸、燒堿(jian)、純(chun)堿(jian)、氯化銨、氯氣(qi)等(deng)(deng)(deng)主要是用(yong)(yong)工(gong)(gong)(gong)業鹽為原(yuan)(yuan)料生(sheng)產的(de)(de)。此外(wai)，還用(yong)(yong)于肥皂(zao)制(zhi)(zhi)造(zao)(zao)、陶瓷(ci)、玻璃生(sheng)產、日用(yong)(yong)化工(gong)(gong)(gong)、石(shi)油(you)鉆探、鉆井(jing)工(gong)(gong)(gong)作液(ye)、完井(jing)液(ye)、石(shi)油(you)化工(gong)(gong)(gong)脫(tuo)水液(ye)、建筑行業早強劑(ji)、生(sheng)產涂料的(de)(de)凝固劑(ji)、橡(xiang)膠(jiao)行業乳膠(jiao)凝結劑(ji)、造(zao)(zao)紙工(gong)(gong)(gong)業添加(jia)劑(ji)及(ji)廢紙張脫(tuo)墨(mo)、化學(xue)工(gong)(gong)(gong)業的(de)(de)無機化工(gong)(gong)(gong)原(yuan)(yuan)料及(ji)硫酸根(gen)脫(tuo)除(chu)劑(ji)，褐藻酸鈉的(de)(de)凝固劑(ji)、防治(zhi)小麥、蘋果、白(bai)菜等(deng)(deng)(deng)腐爛及(ji)食品防腐劑(ji)、制(zhi)(zhi)取金屬鈉及(ji)其他鈉化合物、鋼(gang)鐵熱處理介質等(deng)(deng)(deng)。在(zai)水處理、公(gong)路(lu)除(chu)雪、制(zhi)(zhi)冷冷藏等(deng)(deng)(deng)方面，鹽也有廣泛的(de)(de)用(yong)(yong)途
