寧夏工業鹽在(zai)染(ran)(ran)料(liao)工(gong)(gong)(gong)(gong)業(ye)(ye)(ye)中的(de)(de)(de)應用(yong)(yong)(yong)染(ran)(ran)料(liao)工(gong)(gong)(gong)(gong)業(ye)(ye)(ye)常(chang)(chang)用(yong)(yong)(yong)的(de)(de)(de)原料(liao)如燒堿、純(chun)堿是(shi)鹽(yan)(yan)(yan)為原料(liao)直接(jie)生產出來的(de)(de)(de)，鹽(yan)(yan)(yan)酸(suan)、硫化(hua)(hua)鈉、保險粉等(deng)是(shi)鹽(yan)(yan)(yan)經深加工(gong)(gong)(gong)(gong)制得的(de)(de)(de)化(hua)(hua)工(gong)(gong)(gong)(gong)產品(pin)(pin)；此(ci)外(wai)，還(huan)直接(jie)耗(hao)用(yong)(yong)(yong)大量(liang)的(de)(de)(de)鹽(yan)(yan)(yan)。所(suo)以(yi)(yi)說(shuo)，染(ran)(ran)料(liao)工(gong)(gong)(gong)(gong)業(ye)(ye)(ye)是(shi)除(chu)了氯堿工(gong)(gong)(gong)(gong)業(ye)(ye)(ye)以(yi)(yi)外(wai)，與鹽(yan)(yan)(yan)業(ye)(ye)(ye)關系非常(chang)(chang)密(mi)切的(de)(de)(de)行業(ye)(ye)(ye)之一(yi)。而且(qie)染(ran)(ran)料(liao)生產過(guo)程中幾乎每(mei)個(ge)步(bu)驟都要(yao)耗(hao)用(yong)(yong)(yong)一(yi)定數量(liang)的(de)(de)(de)鹽(yan)(yan)(yan)。在(zai)冶(ye)(ye)金(jin)(jin)工(gong)(gong)(gong)(gong)業(ye)(ye)(ye)中的(de)(de)(de)應用(yong)(yong)(yong)工(gong)(gong)(gong)(gong)業(ye)(ye)(ye)鹽(yan)(yan)(yan)在(zai)冶(ye)(ye)金(jin)(jin)工(gong)(gong)(gong)(gong)業(ye)(ye)(ye)中用(yong)(yong)(yong)作氯化(hua)(hua)焙燒劑和(he)淬火(huo)劑，也作處(chu)理金(jin)(jin)屬(shu)礦石(shi)的(de)(de)(de)脫硫劑和(he)澄清劑。鋼制品(pin)(pin)和(he)鋼軋制品(pin)(pin)浸入食鹽(yan)(yan)(yan)溶液，可使其表面硬化(hua)(hua)并除(chu)去氧化(hua)(hua)膜。帶鋼及(ji)不銹鋼的(de)(de)(de)酸(suan)洗，煉(lian)鋁、電解(jie)解(jie)金(jin)(jin)屬(shu)鈉等(deng)的(de)(de)(de)助焙劑都要(yao)用(yong)(yong)(yong)到(dao)鹽(yan)(yan)(yan)化(hua)(hua)工(gong)(gong)(gong)(gong)產品(pin)(pin)，以(yi)(yi)及(ji)冶(ye)(ye)煉(lian)中的(de)(de)(de)耐(nai)火(huo)材料(liao)等(deng)都需(xu)要(yao)鹽(yan)(yan)(yan)化(hua)(hua)工(gong)(gong)(gong)(gong)產品(pin)(pin)。

在工(gong)業化(hua)的(de)(de)時代(dai)中，人們所(suo)認識(shi)的(de)(de)鹽(yan)(yan)不(bu)是現代(dai)化(hua)學科學中所(suo)說的(de)(de)工(gong)業鹽(yan)(yan)，所(suo)以鹽(yan)(yan)還分為可食(shi)(shi)用鹽(yan)(yan)和不(bu)可食(shi)(shi)用的(de)(de)工(gong)業鹽(yan)(yan)，只有在正確認識(shi)到這一點之(zhi)后，才(cai)可保證不(bu)會因(yin)為誤食(shi)(shi)有毒(du)鹽(yan)(yan)類(lei)而引發群體中了(le)毒(du)事件。

工業鹽的用途

用于肥皂制造、陶瓷、玻璃(li)出(chu)產、日(ri)用化(hua)工、石油鉆探(tan)、鉆井(jing)(jing)工作液(ye)、完井(jing)(jing)液(ye)、石油化(hua)工脫(tuo)水液(ye)、建(jian)筑行業(ye)早強劑(ji)(ji)、出(chu)產涂(tu)料的(de)凝固劑(ji)(ji)、橡(xiang)膠(jiao)行業(ye)乳膠(jiao)凝聚(ju)劑(ji)(ji)、造紙產業(ye)添(tian)加(jia)劑(ji)(ji)及廢紙張(zhang)脫(tuo)墨、化(hua)學產業(ye)的(de)無機化(hua)工原料及硫酸根(gen)脫(tuo)除劑(ji)(ji)等。

工(gong)業鹽水有(you)(you)著(zhu)再生(sheng)離(li)(li)子(zi)(zi)(zi)(zi)交換樹(shu)脂(zhi)(zhi)(zhi)(zhi)的(de)(de)(de)主要功能。水中(zhong)的(de)(de)(de)不良離(li)(li)子(zi)(zi)(zi)(zi)主要由鈣(gai)、鎂(mei)(mei)(mei)離(li)(li)子(zi)(zi)(zi)(zi)組成，一(yi)般去(qu)(qu)除(chu)鈣(gai)鎂(mei)(mei)(mei)離(li)(li)子(zi)(zi)(zi)(zi)的(de)(de)(de)方(fang)法是(shi)，想辦法讓水通過裝有(you)(you)陽離(li)(li)子(zi)(zi)(zi)(zi)交換樹(shu)脂(zhi)(zhi)(zhi)(zhi)的(de)(de)(de)軟水裝置(zhi)設備，將水中(zhong)的(de)(de)(de)鈣(gai)離(li)(li)子(zi)(zi)(zi)(zi)、鎂(mei)(mei)(mei)離(li)(li)子(zi)(zi)(zi)(zi)置(zhi)換出來，隨(sui)著(zhu)樹(shu)脂(zhi)(zhi)(zhi)(zhi)內鈣(gai)離(li)(li)子(zi)(zi)(zi)(zi)、鎂(mei)(mei)(mei)離(li)(li)子(zi)(zi)(zi)(zi)的(de)(de)(de)增加，然后用(yong)樹(shu)脂(zhi)(zhi)(zhi)(zhi)去(qu)(qu)除(chu)鈣(gai)離(li)(li)子(zi)(zi)(zi)(zi)、鎂(mei)(mei)(mei)離(li)(li)子(zi)(zi)(zi)(zi)的(de)(de)(de)效能逐漸降低。當(dang)樹(shu)脂(zhi)(zhi)(zhi)(zhi)吸收(shou)一(yi)定量的(de)(de)(de)工(gong)業鹽中(zhong)的(de)(de)(de)鈣(gai)鎂(mei)(mei)(mei)離(li)(li)子(zi)(zi)(zi)(zi)時(shi)，就必須進行再生(sheng)創造(zao)，而(er)樹(shu)脂(zhi)(zhi)(zhi)(zhi)的(de)(de)(de)再生(sheng)過程就是(shi)用(yong)工(gong)業鹽水沖洗樹(shu)脂(zhi)(zhi)(zhi)(zhi)層，把樹(shu)脂(zhi)(zhi)(zhi)(zhi)上的(de)(de)(de)鈣(gai)鎂(mei)(mei)(mei)離(li)(li)子(zi)(zi)(zi)(zi)置(zhi)換出來，然后樹(shu)脂(zhi)(zhi)(zhi)(zhi)就恢復原有(you)(you)功能。

純(chun)(chun)(chun)堿(jian)(jian)有保質(zhi)期嗎純(chun)(chun)(chun)堿(jian)(jian)學(xue)名碳酸(suan)鈉，俗稱蘇(su)打、石(shi)堿(jian)(jian)、堿(jian)(jian)灰(hui)、堿(jian)(jian)粉、洗滌堿(jian)(jian)，屬(shu)于鹽類，純(chun)(chun)(chun)堿(jian)(jian)外觀為白色粉末或細粒結(jie)晶，味澀，水溶液(ye)呈堿(jian)(jian)性(xing)。純(chun)(chun)(chun)堿(jian)(jian)的分類有很多，按(an)照(zhao)用途有工(gong)業級純(chun)(chun)(chun)堿(jian)(jian)和食品(pin)級純(chun)(chun)(chun)堿(jian)(jian)，按(an)照(zhao)顆(ke)粒密(mi)度可分為輕質(zhi)純(chun)(chun)(chun)堿(jian)(jian)和重質(zhi)純(chun)(chun)(chun)堿(jian)(jian)，按(an)照(zhao)生產工(gong)藝可分為天然(ran)堿(jian)(jian)、氨(an)堿(jian)(jian)法和聯減法，另外還(huan)有副產純(chun)(chun)(chun)堿(jian)(jian)和落地(di)堿(jian)(jian)。

食(shi)品級純堿的保(bao)質期是180天。

工(gong)業純堿(jian)一(yi)般是(shi)不易變質的，一(yi)般沒有保質期，但是(shi)固體(ti)碳酸鈉(na)在(zai)空氣(qi)中(zhong)吸水(shui)性(xing)強，所以(yi)還是(shi)要注意(yi)儲存方法，一(yi)般放在(zai)陰涼(liang)、通風(feng)處，一(yi)定要注意(yi)遠離火種、熱源，要跟酸類等分開存放，放在(zai)密封罐(guan)和玻璃罐(guan)中(zhong)是(shi)明智的選擇了。
