寧夏工業鹽在染(ran)(ran)料(liao)(liao)工(gong)業(ye)(ye)中(zhong)(zhong)的(de)(de)(de)(de)(de)應用(yong)(yong)染(ran)(ran)料(liao)(liao)工(gong)業(ye)(ye)常(chang)用(yong)(yong)的(de)(de)(de)(de)(de)原料(liao)(liao)如燒堿(jian)、純堿(jian)是鹽(yan)為原料(liao)(liao)直(zhi)接生(sheng)產出來的(de)(de)(de)(de)(de)，鹽(yan)酸(suan)、硫(liu)化(hua)鈉、保險粉(fen)等是鹽(yan)經深加工(gong)制得的(de)(de)(de)(de)(de)化(hua)工(gong)產品(pin)(pin)；此外，還直(zhi)接耗用(yong)(yong)大(da)量(liang)的(de)(de)(de)(de)(de)鹽(yan)。所以說，染(ran)(ran)料(liao)(liao)工(gong)業(ye)(ye)是除了氯堿(jian)工(gong)業(ye)(ye)以外，與鹽(yan)業(ye)(ye)關系(xi)非常(chang)密切的(de)(de)(de)(de)(de)行(xing)業(ye)(ye)之一。而且(qie)染(ran)(ran)料(liao)(liao)生(sheng)產過程中(zhong)(zhong)幾乎每個步驟都(dou)要耗用(yong)(yong)一定數量(liang)的(de)(de)(de)(de)(de)鹽(yan)。在冶金(jin)工(gong)業(ye)(ye)中(zhong)(zhong)的(de)(de)(de)(de)(de)應用(yong)(yong)工(gong)業(ye)(ye)鹽(yan)在冶金(jin)工(gong)業(ye)(ye)中(zhong)(zhong)用(yong)(yong)作氯化(hua)焙燒劑(ji)和淬火劑(ji)，也(ye)作處(chu)理金(jin)屬礦石的(de)(de)(de)(de)(de)脫(tuo)硫(liu)劑(ji)和澄清劑(ji)。鋼制品(pin)(pin)和鋼軋制品(pin)(pin)浸入食鹽(yan)溶液，可(ke)使其(qi)表面硬(ying)化(hua)并除去氧化(hua)膜。帶鋼及(ji)不銹鋼的(de)(de)(de)(de)(de)酸(suan)洗(xi)，煉鋁、電(dian)解解金(jin)屬鈉等的(de)(de)(de)(de)(de)助焙劑(ji)都(dou)要用(yong)(yong)到鹽(yan)化(hua)工(gong)產品(pin)(pin)，以及(ji)冶煉中(zhong)(zhong)的(de)(de)(de)(de)(de)耐(nai)火材(cai)料(liao)(liao)等都(dou)需要鹽(yan)化(hua)工(gong)產品(pin)(pin)。

在工業(ye)(ye)化的(de)(de)時代中，人(ren)們所認(ren)(ren)識的(de)(de)鹽(yan)不是(shi)現代化學科學中所說的(de)(de)工業(ye)(ye)鹽(yan)，所以鹽(yan)還分為可(ke)食(shi)用鹽(yan)和不可(ke)食(shi)用的(de)(de)工業(ye)(ye)鹽(yan)，只有(you)在正確認(ren)(ren)識到這一(yi)點之后(hou)，才可(ke)保證不會(hui)因為誤食(shi)有(you)毒鹽(yan)類(lei)而引(yin)發(fa)群體中了毒事件。

工業鹽的用途

用(yong)(yong)于肥皂制造、陶(tao)瓷、玻(bo)璃出產、日用(yong)(yong)化(hua)工(gong)(gong)、石油鉆探(tan)、鉆井工(gong)(gong)作(zuo)液、完井液、石油化(hua)工(gong)(gong)脫(tuo)水(shui)液、建筑行業早強劑、出產涂料的凝(ning)固劑、橡膠行業乳膠凝(ning)聚(ju)劑、造紙(zhi)產業添加劑及(ji)廢紙(zhi)張脫(tuo)墨、化(hua)學產業的無機化(hua)工(gong)(gong)原料及(ji)硫(liu)酸根(gen)脫(tuo)除劑等。

工(gong)業(ye)鹽水有(you)(you)著再生(sheng)離(li)(li)(li)(li)(li)子(zi)(zi)交換(huan)(huan)樹脂(zhi)(zhi)的(de)主要功(gong)能。水中的(de)不良離(li)(li)(li)(li)(li)子(zi)(zi)主要由(you)鈣、鎂(mei)離(li)(li)(li)(li)(li)子(zi)(zi)組成，一(yi)般去除鈣鎂(mei)離(li)(li)(li)(li)(li)子(zi)(zi)的(de)方法是，想辦法讓水通過裝有(you)(you)陽離(li)(li)(li)(li)(li)子(zi)(zi)交換(huan)(huan)樹脂(zhi)(zhi)的(de)軟水裝置設備，將(jiang)水中的(de)鈣離(li)(li)(li)(li)(li)子(zi)(zi)、鎂(mei)離(li)(li)(li)(li)(li)子(zi)(zi)置換(huan)(huan)出來，隨著樹脂(zhi)(zhi)內鈣離(li)(li)(li)(li)(li)子(zi)(zi)、鎂(mei)離(li)(li)(li)(li)(li)子(zi)(zi)的(de)增加，然(ran)后(hou)用樹脂(zhi)(zhi)去除鈣離(li)(li)(li)(li)(li)子(zi)(zi)、鎂(mei)離(li)(li)(li)(li)(li)子(zi)(zi)的(de)效能逐漸降低。當樹脂(zhi)(zhi)吸(xi)收一(yi)定(ding)量的(de)工(gong)業(ye)鹽中的(de)鈣鎂(mei)離(li)(li)(li)(li)(li)子(zi)(zi)時，就(jiu)必須(xu)進行再生(sheng)創造，而樹脂(zhi)(zhi)的(de)再生(sheng)過程就(jiu)是用工(gong)業(ye)鹽水沖洗樹脂(zhi)(zhi)層，把樹脂(zhi)(zhi)上的(de)鈣鎂(mei)離(li)(li)(li)(li)(li)子(zi)(zi)置換(huan)(huan)出來，然(ran)后(hou)樹脂(zhi)(zhi)就(jiu)恢復原有(you)(you)功(gong)能。

純(chun)(chun)(chun)(chun)堿(jian)(jian)(jian)(jian)(jian)有(you)(you)保質期嗎(ma)純(chun)(chun)(chun)(chun)堿(jian)(jian)(jian)(jian)(jian)學名碳酸鈉(na)，俗(su)稱蘇(su)打、石堿(jian)(jian)(jian)(jian)(jian)、堿(jian)(jian)(jian)(jian)(jian)灰(hui)、堿(jian)(jian)(jian)(jian)(jian)粉、洗滌堿(jian)(jian)(jian)(jian)(jian)，屬于(yu)鹽(yan)類(lei)，純(chun)(chun)(chun)(chun)堿(jian)(jian)(jian)(jian)(jian)外觀為(wei)白色粉末或細粒(li)結晶，味澀，水溶液呈堿(jian)(jian)(jian)(jian)(jian)性。純(chun)(chun)(chun)(chun)堿(jian)(jian)(jian)(jian)(jian)的分類(lei)有(you)(you)很多，按照用(yong)途(tu)有(you)(you)工(gong)業級純(chun)(chun)(chun)(chun)堿(jian)(jian)(jian)(jian)(jian)和(he)(he)食品級純(chun)(chun)(chun)(chun)堿(jian)(jian)(jian)(jian)(jian)，按照顆粒(li)密度可(ke)分為(wei)輕(qing)質純(chun)(chun)(chun)(chun)堿(jian)(jian)(jian)(jian)(jian)和(he)(he)重質純(chun)(chun)(chun)(chun)堿(jian)(jian)(jian)(jian)(jian)，按照生產工(gong)藝可(ke)分為(wei)天然堿(jian)(jian)(jian)(jian)(jian)、氨堿(jian)(jian)(jian)(jian)(jian)法和(he)(he)聯減法，另外還有(you)(you)副產純(chun)(chun)(chun)(chun)堿(jian)(jian)(jian)(jian)(jian)和(he)(he)落地堿(jian)(jian)(jian)(jian)(jian)。

食品(pin)級純(chun)堿的(de)保(bao)質(zhi)期(qi)是180天(tian)。

工業純堿一般(ban)(ban)(ban)是不易(yi)變質的，一般(ban)(ban)(ban)沒有保(bao)質期，但是固體(ti)碳(tan)酸鈉在(zai)空(kong)氣中吸(xi)水性強，所以還是要(yao)(yao)注意儲存方法，一般(ban)(ban)(ban)放(fang)在(zai)陰涼、通(tong)風處，一定要(yao)(yao)注意遠離(li)火種、熱源，要(yao)(yao)跟酸類等分開存放(fang)，放(fang)在(zai)密(mi)封罐和玻璃罐中是明(ming)智(zhi)的選擇了。
