隨著現代社會對工業鹽的(de)(de)大力需求(qiu),我們是對工業鹽的(de)(de)隱藏(zang)特性進行不斷的(de)(de)研究與討論,下面就由小(xiao)編(bian)為(wei)大家介(jie)紹一下日常工業鹽的(de)(de)吸潮性。
吸(xi)潮(chao)(chao)性(xing):工業(ye)鹽的(de)表面通(tong)常被(bei)一層薄(bo)膜狀的(de)飽和鹽溶(rong)液所包(bao)圍(wei),當(dang)這層薄(bo)膜溶(rong)液的(de)蒸氣(qi)(qi)(qi)壓(ya)低于空(kong)(kong)(kong)氣(qi)(qi)(qi)中(zhong)水蒸氣(qi)(qi)(qi)分壓(ya)時(shi),工業(ye)鹽就吸(xi)附空(kong)(kong)(kong)氣(qi)(qi)(qi)中(zhong)的(de)水分而潮(chao)(chao)解,反(fan)之,當(dang)高(gao)于空(kong)(kong)(kong)氣(qi)(qi)(qi)中(zhong)水蒸氣(qi)(qi)(qi)分壓(ya)時(shi)則呈現干燥狀態(tai),當(dang)然,這只是在工業(ye)鹽被(bei)暴露在空(kong)(kong)(kong)氣(qi)(qi)(qi)中(zhong)才有(you)的(de)現象,密(mi)閉在包(bao)裝袋中(zhong)與(yu)周圍(wei)空(kong)(kong)(kong)氣(qi)(qi)(qi)隔絕(jue)的(de)其他鹽是不會潮(chao)(chao)解的(de)。
對于以上工(gong)業(ye)鹽(yan)的吸潮性大(da)家都了解了嗎(ma),正是因為工(gong)業(ye)鹽(yan)有(you)著不同尋常的特點,所(suo)以才被成(cheng)為化學原料之(zhi)母,被廣(guang)泛使用。
工業(ye)(ye)鹽我(wo)們并不陌生,你可能并沒有(you)(you)見過,但是(shi)生活當(dang)中(zhong)很多物質都是(shi)以(yi)工業(ye)(ye)鹽為原料制作而成(cheng)的,所以(yi)它被(bei)稱之為化(hua)學原料之母(mu)。那么有(you)(you)關工業(ye)(ye)園的吸潮性你是(shi)否有(you)(you)所了解(jie)呢?
工(gong)業鹽(yan)(yan)的(de)(de)(de)(de)表面通(tong)常被一層薄(bo)膜的(de)(de)(de)(de)飽和鹽(yan)(yan)溶液所包圍,當薄(bo)膜溶液中(zhong)的(de)(de)(de)(de)蒸汽降(jiang)低空(kong)氣中(zhong)的(de)(de)(de)(de)水汽分壓(ya)時(shi),工(gong)業鹽(yan)(yan)被空(kong)氣中(zhong)的(de)(de)(de)(de)水汽吸附(fu)而(er)潮解,相反,呈現(xian)(xian)的(de)(de)(de)(de)是干燥狀態,當然(ran),這只是工(gong)業鹽(yan)(yan)是暴露在空(kong)氣中(zhong)的(de)(de)(de)(de)現(xian)(xian)象,在密封袋中(zhong)工(gong)業鹽(yan)(yan)是密封的(de)(de)(de)(de),與(yu)周(zhou)圍空(kong)氣不潮解。
如果工(gong)業(ye)鹽長時(shi)間(jian)暴(bao)露在(zai)外,會(hui)接觸到空氣(qi)中(zhong)的二氧化碳和水。工(gong)業(ye)鹽與二氧化碳和水反(fan)應(ying)生(sheng)成碳酸氫鈉,就會(hui)呈現出我們常看到的結塊現象。工(gong)業(ye)鹽不能長時(shi)間(jian)暴(bao)露在(zai)外,容易(yi)溶解(jie)吸(xi)(xi)濕(shi),工(gong)業(ye)鹽吸(xi)(xi)濕(shi)需要更加重視。
