工(gong)(gong)業(ye)鹽(yan)屬于工(gong)(gong)業(ye)用鹽(yan)，工(gong)(gong)業(ye)鹽(yan)和(he)食用鹽(yan)的(de)(de)區別很(hen)多，不管是屬性還(huan)是使(shi)(shi)用方法都有很(hen)大的(de)(de)不同，接下(xia)(xia)來為大家介紹一(yi)下(xia)(xia)工(gong)(gong)業(ye)鹽(yan)的(de)(de)屬性和(he)使(shi)(shi)用：

    工業鹽(yan)的(de)屬(shu)性：

　　工(gong)(gong)(gong)(gong)業鹽(yan)在工(gong)(gong)(gong)(gong)業上(shang)的用(yong)途很(hen)廣，是化(hua)學工(gong)(gong)(gong)(gong)業的基本原(yuan)料(liao)(liao)之(zhi)(zhi)一，被稱為“化(hua)學工(gong)(gong)(gong)(gong)業之(zhi)(zhi)母”。基本化(hua)學工(gong)(gong)(gong)(gong)業主要(yao)產品(pin)中的鹽(yan)酸、燒堿、純堿、氯(lv)(lv)化(hua)銨、氯(lv)(lv)氣(qi)等主要(yao)是用(yong)工(gong)(gong)(gong)(gong)業鹽(yan)為原(yuan)料(liao)(liao)生產的。

工業(ye)鹽(yan)(yan) 指的(de)(de)是原鹽(yan)(yan)，原鹽(yan)(yan)有(you)湖鹽(yan)(yan)、井鹽(yan)(yan)和(he)海鹽(yan)(yan)之分，其(qi)中(zhong)(zhong)因(yin)為(wei)海鹽(yan)(yan)中(zhong)(zhong)的(de)(de)海水(shui)溶(rong)入了多種元素(su)，所以(yi)海鹽(yan)(yan)的(de)(de)工業(ye)價(jia)值(zhi)相對要高(gao)些，食用價(jia)值(zhi)要低些。工業(ye)鹽(yan)(yan)是白(bai)色(se)(se)無味或者是灰白(bai)色(se)(se)有(you)色(se)(se)，無色(se)(se)結晶性(xing)粉末，熔(rong)點240℃（分解）。不溶(rong)于水(shui)，乙醇(chun)和(he)一般(ban)的(de)(de)有(you)機(ji)溶(rong)劑，微溶(rong)于水(shui)，但易(yi)溶(rong)于氫氧(yang)化鈉(na)(na)溶(rong)液和(he)氨水(shui)，溶(rong)于100℃沸(fei)水(shui)160。其(qi)堿鹽(yan)(yan)可溶(rong)于水(shui)，一般(ban)用乙二胺四乙酸鈉(na)(na)鹽(yan)(yan)代替(ti)EDTA。

      工業鹽使用：

　　EDTA是一種重要(yao)的絡(luo)合(he)(he)劑(ji)(ji)工(gong)(gong)(gong)(gong)業(ye)(ye)鹽。 EDTA工(gong)(gong)(gong)(gong)業(ye)(ye)鹽用(yong)途很廣，可(ke)以用(yong)作漂白(bai)，染色助劑(ji)(ji)定影(ying)液(ye)體，纖維加工(gong)(gong)(gong)(gong)助劑(ji)(ji)，化(hua)妝品(pin)(pin)添加劑(ji)(ji)，血(xue)抗凝，洗滌劑(ji)(ji)，穩定劑(ji)(ji)，合(he)(he)成(cheng)橡膠聚合(he)(he)引發(fa)劑(ji)(ji)的著色感光材料沖洗加工(gong)(gong)(gong)(gong)，EDTA是具有代(dai)表(biao)性的物質螯合(he)(he)劑(ji)(ji)。稀土(tu)元素和過渡金屬可(ke)以與堿金屬，以形(xing)成(cheng)穩定的水溶性絡(luo)合(he)(he)物。工(gong)(gong)(gong)(gong)業(ye)(ye)鹽在其他行(xing)業(ye)(ye)也(ye)有很好的應用(yong)，比如：造紙行(xing)業(ye)(ye)制造紙漿、漂白(bai)紙漿以及作填充(chong)劑(ji)(ji)等，要(yao)用(yong)硫(liu)酸鈉、硫(liu)酸鎂、氯酸鈉等鹽化(hua)工(gong)(gong)(gong)(gong)產(chan)品(pin)(pin)。火柴、火藥、印(yin)刷、電影(ying)和照(zhao)相行(xing)業(ye)(ye)也(ye)廣泛使用(yong)多種鹽化(hua)工(gong)(gong)(gong)(gong)產(chan)品(pin)(pin)。

   在(zai)鹽(yan)田曬(shai)制的(de)(de)海鹽(yan)及在(zai)天然鹽(yan)湖或鹽(yan)礦開采出的(de)(de)未經人工處(chu)理的(de)(de)湖鹽(yan)或巖鹽(yan)等的(de)(de)統(tong)稱。主要組分是氯化鈉，夾雜有不溶性(xing)泥沙和可溶性(xing)的(de)(de)鈣、鎂鹽(yan)類。

鍋爐(lu)用(yong)水一般要求鹽度不超過20PPM.

概念上講是用(yong)如鍋爐給水(shui)(shui)處理，確切的(de)說是鍋爐給水(shui)(shui)處理(軟化(hua)器)設(she)備的(de)再生劑。理論(lun)上說；所飲(yin)用(yong)的(de)井水(shui)(shui)、城市自來水(shui)(shui)都含有鈣、鎂離子(通常稱(cheng)為硬水(shui)(shui))，這是結水(shui)(shui)垢的(de)物質(zhi)必須除(chu)掉，就象(xiang)燒開水(shui)(shui)的(de)水(shui)(shui)壺一(yi)(yi)樣(yang)，壺底一(yi)(yi)層水(shui)(shui)垢。所以這樣(yang)的(de)水(shui)(shui)是不能直接(jie)進入鍋爐，必需(xu)經過(guo)軟化(hua)器設(she)備軟化(hua)后(hou)(稱(cheng)為軟水(shui)(shui))才能供鍋爐使用(yong)。
