工业用盐与食用盐的区别有哪些

编辑:山东合展化工有限公司时(shi)间(jian):2022-07-14

  工(gong)业盐(yan)冒充食盐(yan)并(bing)不少见。非(fei)法(fa)非(fei)法(fa)商人利用(yong)工(gong)业盐(yan)和食用(yong)盐(yan)的(de)价差(cha),开办非(fei)法(fa)生意。那么(me)工(gong)业盐(yan)是什(shen)么(me)物(wu)质呢?工(gong)业用(yong)盐(yan)和食用(yong)盐(yan)有什(shen)么(me)区别?对人体有什(shen)么(me)危害?我(wo)认为需要作一个简单的(de)介绍。

  J9九游会AG 来谈谈三个相(xiang)关的概念:盐、工业盐和食用(yong)盐。

  1.盐

  从化(hua)(hua)学角度看,盐(yan)(yan)是指金属离(li)(li)子或铵离(li)(li)子(NH4+)与酸(suan)离(li)(li)子或非(fei)金属离(li)(li)子结合形成的化(hua)(hua)合物。如氯(lv)化(hua)(hua)钠、硝酸(suan)钙(gai)、硫酸(suan)亚铁、乙(yi)酸(suan)铵、硫酸(suan)钙(gai)、氯(lv)化(hua)(hua)铜、乙(yi)酸(suan)钠等化(hua)(hua)合物。J9九游会AG 日常生活中提到(dao)的盐(yan)(yan)也是食用盐(yan)(yan)的缩写。

  2.工(gong)业盐

  工(gong)业盐(yan)在工(gong)业中(zhong)应用(yong)广泛(fan)。它是化学工(gong)业中(zhong)基本的原料之(zhi)一。其主(zhu)(zhu)要成分是氯化钠(na),被誉为(wei)“化工(gong)之(zhi)母”。基础化工(gong)主(zhu)(zhu)要产(chan)品中(zhong)的盐(yan)酸、烧碱(jian)、纯碱(jian)、氯化钠(na)、氯气主(zhu)(zhu)要以工(gong)业盐(yan)为(wei)原料生产(chan)。

  3.食用盐

  食(shi)用(yong)(yong)盐(yan)(yan)(yan)是(shi)指(zhi)以氯化钠(na)为主(zhu)要成分,从海水、地(di)下岩(矿(kuang))盐(yan)(yan)(yan)矿(kuang)床、天然卤(盐(yan)(yan)(yan))水等中(zhong)提(ti)取的(de)加工食(shi)用(yong)(yong)盐(yan)(yan)(yan),食(shi)用(yong)(yong)盐(yan)(yan)(yan)是(shi)烹饪中(zhong)常(chang)用(yong)(yong)的(de)调味(wei)品之一,也是(shi)人(ren)体正常(chang)生理(li)活(huo)动(dong)不可缺(que)少的(de)物(wu)质,我国对食(shi)用(yong)(yong)盐(yan)(yan)(yan)的(de)质量有严格(ge)的(de)规定。

  工(gong)(gong)(gong)业(ye)用(yong)(yong)(yong)盐(yan)与(yu)食(shi)(shi)(shi)用(yong)(yong)(yong)盐(yan)的异同(tong)(tong)有(you)哪些呢?说(shuo)到工(gong)(gong)(gong)业(ye)盐(yan)和食(shi)(shi)(shi)用(yong)(yong)(yong)盐(yan)的异同(tong)(tong),相同(tong)(tong)的是(shi)(shi)(shi)两者都以氯(lv)化(hua)钠为(wei)主要成分(fen)(fen)。区别(bie)只(zhi)是(shi)(shi)(shi)标准(zhun)(zhun)不(bu)(bu)同(tong)(tong),用(yong)(yong)(yong)途不(bu)(bu)同(tong)(tong)。不(bu)(bu)用(yong)(yong)(yong)说(shuo),一(yi)个是(shi)(shi)(shi)工(gong)(gong)(gong)业(ye),一(yi)个是(shi)(shi)(shi)食(shi)(shi)(shi)品(pin)。那么,标准(zhun)(zhun)为(wei)何不(bu)(bu)同(tong)(tong)呢?让J9九游会AG 来看(kan)看(kan)国标GB/T 5662-2003《工(gong)(gong)(gong)业(ye)盐(yan)》和GB2211-2003《食(shi)(shi)(shi)用(yong)(yong)(yong)盐(yan)卫(wei)生标准(zhun)(zhun)》中(zhong)有(you)关(guan)工(gong)(gong)(gong)业(ye)盐(yan)和食(shi)(shi)(shi)用(yong)(yong)(yong)盐(yan)理化(hua)指(zhi)标的有(you)关(guan)规(gui)定。这(zhei)里主要对(dui)理化(hua)指(zhi)标进行对(dui)比分(fen)(fen)析。有(you)关(guan)工(gong)(gong)(gong)业(ye)盐(yan)和食(shi)(shi)(shi)用(yong)(yong)(yong)盐(yan)的其他(ta)标准(zhun)(zhun),感兴趣的朋友可以查看(kan)相应的标准(zhun)(zhun)。

  “工业盐(yan)”通常(chang)指亚硝酸盐(yan)。工业盐(yan)主(zhu)要用于(yu)制(zhi)碱、锅(guo)炉软水、染料、肥皂洗衣(yi)粉、饲料加工等领域,但流入食用领域时(shi)会产(chan)生危(wei)害。

  食用工业盐(yan)后,会感到头晕(yun)、呕吐、腹泻和虚弱。工业盐(yan)含有亚(ya)硝酸(suan)盐(yan)。人体摄入0.3-0.5克亚(ya)硝酸(suan)盐(yan)可(ke)引(yin)起急性(xing)中毒,3克可(ke)致(zhi)死(si)。一旦中毒,会引(yin)起头晕(yun)、头晕(yun)、耳(er)鸣(ming)、全身无(wu)力、手脚麻(ma)木(mu)、恶心(xin)、呕吐、腹泻、紫绀(gan)、心(xin)悸、血压下(xia)降、呼(hu)吸(xi)困难等症状。严(yan)重时会引(yin)起抽搐和昏迷。如(ru)果抢救不及时或摄入过(guo)多(duo),会导致(zhi)呼(hu)吸(xi)衰竭和死(si)亡。所以J9九游会AG 用盐(yan)的时候(hou)要非常小心(xin)。

  以上是小编带给您(nin)的工业用盐的相关(guan)介绍,希(xi)望能对您(nin)有(you)所帮助。如(ru)果您(nin)想(xiang)了解(jie)更多相关(guan)信息,欢迎(ying)访问J9九游会AG 的网站,J9九游会AG 将竭(jie)诚为(wei)您(nin)服务(wu)。
