Gabatarwa ga ilimin zinc, ta yaya ake hada zinc karfe?
Zinc wani sinadari ne. Alamar sinadarai ita ce Zn, kuma lambar atom ɗin sa ita ce 30. Tana cikin lokaci na huɗu da rukuni ⅡB na tebur na abubuwan sinadaran. Zinc karfe ne mai haske mai launin toka kuma karfe na "na kowa" na hudu. A masana'antar zamani, zinc ba zai iya maye gurbinsa ba a masana'antar batir kuma yana da mahimmancin ƙarfe. Bugu da kari, zinc shima yana daya daga cikin muhimman abubuwan ganowa ga jikin dan adam kuma yana taka muhimmiyar rawa.
Zinc yana da wuyar ƙonewa a cikin iska kuma yana fitar da haske mai ƙarfi a cikin iskar oxygen. Akwai wani Layer na zinc oxide a saman zinc, wanda ke fitar da farin hayaki idan ya kone. Babban abin da ke tattare da farin hayaki shine zinc oxide, wanda ba wai kawai ya toshe kona zinc ba, har ma yana nuna launin harshen wuta don samar da haske. Zinc yana da sauƙin narkewa a cikin acid kuma yana iya sauƙin maye gurbin zinariya, azurfa, jan karfe, da dai sauransu daga maganin. Fim ɗin oxide na zinc yana da babban wurin narkewa, amma wurin narkewa na zinc ƙarfe yana da ƙasa sosai. Don haka dumama flakes na zinc a kan fitilar barasa zai narke kuma ya yi laushi da tukwane, amma ba ya faɗi ƙasa, daidai saboda tasirin fim ɗin oxide. Ana amfani da Zinc galibi a ƙarfe, ƙarfe, injina, lantarki, sinadarai, masana'antar haske, soja da filayen magunguna.
warware ƙuduri:
1. Ka zubar da 360g na zinc na ƙarfe kuma a hankali ƙara shi zuwa 3340ml na 15% sulfuric acid bayani, da zafi zuwa 70 ° C don amsawa. Lokacin da H2 ya daina ambaliya, a tsoma shi da 1200ml na ruwa don shirya maganin zinc sulfate, cire 50ml, kuma yi amfani da sauran don amfani daga baya. 4g na sodium carbonate aka kara zuwa 50ml na diluted bayani, da kuma precipitate zinc carbonate hazo an wanke sau uku da ruwa (300ml kowane lokaci) don amfani. Narkar da 7.5 g na ferrous sulfate heptahydrate a cikin 500 ml na ruwa, acidify tare da 1 ml na babban sa tsarki sulfuric acid, zafi, da kuma ƙara 30% hydrogen peroxide dropwise don maida duk Fe2+ ions a cikin bayani zuwa Fe3+ ions. Ƙara maganin sulfate na baƙin ƙarfe da aka shirya zuwa bayani na zinc sulfate da aka ambata a sama, kuma ƙara shirye-shiryen zinc carbonate da aka shirya tare da motsawa, sa'an nan kuma zafi zuwa 30-40ºC a ƙarƙashin saurin motsawa, kuma bar shi ya tsaya. Bayan maganin ya bayyana, tace shi. [ Cire Fe (OH) 3 yana haɓaka tare da As, P, Sb da sauran ƙazanta]. Filtrate ɗin yana da wutar lantarki kuma an daidaita ƙimar PH don sanya Kongo ja ɗan shuɗi. A lokacin electrolysis, yi amfani da premium sa tsarki ko tutiya flakes a matsayin cathode, masana'antu zinc a matsayin anode, nisa tsakanin biyu lantarki ne 2-3cm, da ƙarfin lantarki tsakanin biyu electrodes ne 6V, da kuma halin yanzu yawa ya dogara da zafin jiki na electrolyte. Bayan 200g na zinc da aka haɗe, dole ne a sake maganin electrolyte da baƙin ƙarfe sulfate da zinc carbonate bisa ga hanyar da ke sama.
2. Ana shirya shirye-shiryen zinc ta hanyar narkewar zinc blende ZnS a matsayin babban kayan albarkatun kasa. A masana'antu, ZnS yawanci oxidized da calcined a cikin wani oxide tare da mai kyau reactivity. Sa'an nan kuma yi amfani da hanyar rage zafi da hanyar electrolysis don shirya zinc. Ana sanya cajin da aka yi da toshe gasasshen tutiya da foda na kwal a cikin tanderun da ke narkewar zinc a 1300 ~ 1350 ° C don amsawa, tururin zinc na ƙarfe da aka samar ta hanyar rage ɗaukar nauyi yana shiga cikin na'urar na'urar tutiya ta hanyar bututun, kuma an kama zinc ɗin ƙarfe. Zinc ɗin ƙarfe da aka samu ta wannan hanyar yana da ƙayyadaddun ƙayyadaddun ƙazanta. Don samun mafi kyawun zinc, ana buƙatar distillation injin.
3. Narkar da zinc oxide a cikin kayan calcined tare da sulfuric acid, cire baƙin ƙarfe ta oxidation, cire cobalt, jan karfe, nickel da sauran ƙazanta tare da foda zinc, sa'an nan kuma sanya shi a cikin kwayar halitta ta electrolytic tare da gubar a matsayin anode da aluminum farantin kamar cathode. A lokacin electrolysis, zinc na ƙarfe yana ajiyewa akan farantin aluminum kuma ana fitar dashi ya zama samfur. Tsaftar zinc na ƙarfe da electrolysis ke samarwa zai iya kaiwa 99.99%.
