Mafala Akutoma Nanu Kudziwa, zincy zinc zojambula bwanji?
Zinc ndi chinthu chamankhwala. Chizindikiro chake cha zn, ndipo nambala yake ya atomiki ndi 30. Ili nthawi yachinayi ndi gulu ⅱb ya nyengo ya nyengo ya mankhwala. Zinc ndi chitsulo chopepuka cha imvi ndi chitsulo chachinayi "chofala". Mu makampani amakono, zinc sakhala mu malonda popanga batiri ndipo ndi chitsulo chofunikira kwambiri. Kuphatikiza apo, zinki ndi imodzi mwazinthu zofunikira kwa thupi la munthu ndipo zimagwira gawo lofunika kwambiri.
Zinc ndizovuta kuwotcha mlengalenga ndikutulutsa kuwala koyera koyera kwa mpweya. Pali wosanjikiza wa ma oxide oxide pamwamba pa zinc, yomwe imatulutsa utsi woyera pomwe umayaka. Gawo lalikulu la utsi woyera ndi zinc oxide, lomwe sikuti limangoyang'ana zitsulo, komanso zimawonetsa mtundu wa lawi kuti apange kuwala kotumbulu. Zinc imasungunuka mosavuta mu acid ndipo imatha m'malo mosavuta kulowa golide, siliva, mkuwa, etc. kuchokera yankho. Kanema wa oxide wa zinc ali ndi maziko apamwamba, koma malo osungunuka a zitsulo ndi otsika kwambiri. Chifukwa chotenthetsa zitsamba za chithule choledzera chidzasungunuke ndi kufewetsa zitsulo zam'mimba, koma sizigwa, ndendende chifukwa cha momwe mafilimu owerengera. Zinc imagwiritsidwa ntchito makamaka pazitsulo, mapoto, makina, makampani amagetsi, magetsi, operiridwa, minda yankhondo.
Tsimikizani Kusintha:
1. Vacuum pansi pa miyala yamiyala ndikuwonjezera pang'onopang'ono mpaka 3340ml wa 15% sulfuric acid yankho, ndi kutentha kwa 70 ° C POPHUNZIRA. Pamene H2 sakusefukira, kuchepetsa ndi ma 1200ml amadzi kuti akonzekere yankho la zinc sulfate, tengani 50ml, ndikugwiritsa ntchito zotsalazo pogwiritsa ntchito pambuyo pake. A 4g ya carbonate ya sodium adawonjezeredwa 50ml ya yankho losakanikirana, ndi mpweya wokhazikika wa zinc Crubonita katatu ndi madzi (300ml nthawi iliyonse) kuti mugwiritse ntchito. Sungunulani kuti 7.5 g ya ferrous sulfate Helfate mu 500 ml ya madzi, acid ndi 1 ml ya grade yapamwamba ya sulfuride yopanda kanthu kuti asinthe nyama yonse ya feroxice +. Onjezani njira yokonzekereratu yothekera ku Sulfate Yapamwamba ya Sulfate, ndipo onjezani ma carbonate a carbonate yopanga, kenako kutentha mpaka 30-40ºC mwachangu, ndikuime. Pambuyo yankho ndi lomveka, muzisefa. [Kuchotsa Fe (oh) 3 apansi ndi, p, SB ndi zosafunikira]. Zosefera ndi mankhwala a electrolyzed ndi mtengo wa pH zimasinthidwa kuti Congo ikhale yofiyira pang'ono. Pa electrolysis, gwiritsani ntchito zidutswa za premium kapena zinc monga momwe zatoto, zincrialrialrial monga mawonekedwe awiriwo ndi 2V, ndipo kuchuluka kwa ma electrodis ndi 6v Pambuyo pa 200g ya zinc yazimiririka, ma electrolyte ayenera kuthandizidwanso ndi sulfate ya chitsulo ndi carbonate molingana ndi njira yomwe ili pamwambapa.
2. Kukonzekera kwa zinc kumakonzedwa ndikusungunuka zinc Contee ZNS monga zinthu zazikuluzikulu. Momwemonso, ZNS nthawi zambiri imakhala yoyamikidwa ndikuwerengera kwa oxide wokhala ndi kukhazikitsidwa kwabwino. Kenako gwiritsani ntchito njira yochepetsera kutentha ndi njira ya electrolysis kukonzekera zinc. Mlandu wopangidwa ndi zinc Roasation block ndi ufa wa malasha amayika mu ng'anjo ya zinc ~ ~ 1350 ° zomwe zimapangidwa ndi zitsamba zopangidwa ndi zitsulo, ndipo zitsulo zitsulo zimagwidwa. Zitsulo zam'mimba zomwe zapezeka ndi njirayi ndizosadetsa kwambiri. Kuti mupeze zoyera, kusanja kumafunikira.
3. Sungunulani ma oxide oxide munkhani ndi sulfuric acid, chotsani chitsulo, chotsani mu ufa wa electrolytic, kenako ndikuyika mbale ya sode yokhala ndi chivine. Pa electrolysis, metallic zinc amasungidwa pambale ya aluminium ndikuyipitsidwa kuti ikhale chinthu. Kuyera kwa zitsulo zinc yopangidwa ndi electrolysis imatha kufikira 99.99%.

Chodzikanira: Zambiri zomwe zili m'nkhaniyi ndizazomwe mungafotokozere zokhazokha, osati monga lingaliro lachindunji. Ngati simukufuna kusiya ufulu wanu walamulo, chonde titumizireni patapita nthawi.
