Zinc ndi chitsulo choyera choyera chokhala ndi mawonekedwe a hertal oyandikira. Imakhala ndi malo osungunula 419.58 ° C, malo owira 907 ° C, kulimba kwa ma mohs kwa 2.5, kunyinyirika kwamagetsi kwa 2,02 ωna mm.
Zinc Dzuwa limabwera m'magawo awiri: zowoneka bwino komanso zowoneka ngati. Flake-Nthumba ya zinzi ili ndi mphamvu yayikulu kwambiri.
Mankhwala, fumbi la zikisi limayandikana. Munthawi zonse za m'mlengalenga, zimapanga zocheperako, zowirira za carbonate yoyambira pansi, yomwe imalepheretsa oxidation, ndikupangitsa kuti zisawonongeke kwambiri mumlengalenga. Komabe, sizikugwirizana ndi kuchuluka kwa acidic kapena mchere wa alkaline. Imasungunuka mu itorganic acids, zodetsa, ndi aceti acid koma ndizopanda madzi.
Zinc Fumbi limayaka ndi lawi loyera loyera bwino mpweya wabwino koma ndizovuta kuyimitsa mpweya wabwinobwino, motero sichinapangidwe ngati cholimba. Mu malo abwinobwino, zinc Nthambi zimakhudzana ndi chinyezi kapena madzi kuti mupange mpweya wa hydrogen, koma kuchuluka kwa ntchito hydrogen, osakwana 1 L / (KAG · (KIGE). Chifukwa chake, zinc Nthumbe sinasanjidwe ngati chinthu chomwe chimatulutsa mpweya woyaka womwe umalumikizana ndi madzi. Komabe, kwa otetezeka komanso osungirako, ndikofunikira kuchita monga gulu la anthu 4.3 Zowopsa (zinthu zomwe ndizowopsa zikanyowa). Pakadali pano, malamulo pa kusungidwa ndi mayendedwe a ufa wa zinc ufa kusiyanasiyana kudera lina ku China, ndi ena kukhala oganiza bwino komanso ena okhazikika.
Zinc Fumbi limatha kuphulika, njira yolumikizira mpweya. Mwachitsanzo, fumbi la micron-stud-incron limakhala ndi nthawi yovuta kwambiri ya 180 ms, ndi malire ophulika a 1500-2000 g / m³. Pa ndende ya 5000 g / m³, imafikira kuchuluka kwambiri, kuchuluka kwa kuphulika kwaphulika, komanso index yophukira, komwe ndi 0,481 MPA, ndi 12.67 Mpamwamba. Mlingo wa zitsamba wa micron-ufa wa zinc ufa wotchulidwa ngati st1, kuwonetsa chiopsezo chotsika.
Njira Zopangira:
1. Mmwamba-zinc Ore smelting:
China ili ndi zopangira zochulukirapo, makansadwe pafupifupi 20% ya malo osungirako padziko lonse lapansi, yachiwiri kokha ku Australia. China ndi chopanga chachikulu cha zinzi, zimapereka gawo limodzi mwa magawo atatu a kupanga padziko lonse lapansi, litakhazikitsidwa padziko lonse lapansi. Njira yosungunulira imaphatikizapo kutsuka zinc ore kuti mupeze zinc sulfide amangokhazikika, omwe amachepetsedwa kuti akhazikike zinc
Mu 2022, China chanc's zinc Ingotic adafikira matani 6.72 miliyoni. Mtengo wa Zinc Misanda pamapeto pake pamapeto pake amawona mtengo wa zinc ufa ufa, zomwe zitha kuwerengedwa pa 1.15-1.2 nthawi zonse mtengo wa zincbots.
2. Zinc Fumbi-anomiation njira: **
Oyeza kwambiri (99.5%) zinc) zinc Zinni zinchi zimasamutsidwa kuti zisawonongeke komanso kuwonongedwa mozama komanso mikhalidwe yolumikizidwa, yokhala ndi mpweya wokakamizidwa ndi 0.3-0.6 MPA. Ufa wa atomated unn umasonkhanitsidwa munthawi yafumbi kenako ndikudutsa sume yothilira kwambiri kuti ilekanitse mkati mwa tinthu tating'onoting'ono tisanakhazikitse.

Njirayi imatha kukhala youma kapena yonyowa, ndikupanga fumbi louma louma kapena lotalika ngati fumbi la flake. Mwachitsanzo, mphero zonyowa za mpira zimatha kupanga phala ngati flaked zinc. Atomime ufa ufa wosakanizidwa ndi Aliphac hydrobon solcon ndi mafuta ochepa mu mphero. Chinyengo chomwe mukufuna ndikuchita bwino, kusalala kumasefedwa kuti apange keke yosefera ndi 90% ZICS. Keke ya fyulumu ndiye yosakanikirana kuti ipange zonunkhira zam'madzi zokutira, ndi zitsulo zoposa 90%.
Gwiritsani Ntchito:
Zinc Fumbi limagwiritsidwa ntchito mu makampani ophatikizika, monganso zokutira zopangidwa ndi zinthu zachilengedwe. Amagwiritsidwanso ntchito mu utoto, metallingo, mankhwala, ndi mankhwala. Maakaunti ophatikizira pafupifupi 60% ya ufa wa zinc, wotsatiridwa ndi makampani opanga mankhwala (28%) ndi mafakitale opangira mankhwala (4%).
Nthambi yazitsulo ili ndi dothi lozungulira, kuphatikiza fumbi lam'madzi ndi lamphamvu kwambiri. Omaliza ali ndi zinthu zapamwamba, zodetsa nkhawa, tinthu tating'ono tating'ono, ntchito zabwino, kuphatikiza kwapadera tinthu tating'onoting'ono, komanso kuphatikizika kwambiri kagawo kamene kakugawidwa, kumapangitsa kuti ikhale yopanga kwambiri. Nthambi yabwino kwambiri ya ultra-ntchito imagwiritsidwa ntchito kwambiri ndikugwiritsa ntchito zokuthandizani komanso kugwiritsa ntchito njira zogwirira ntchito, makamaka m'makanema olemera kapena zolembedwa mwachindunji. Pakuchikutira, nthaka inc ndi tinthu tating'onoting'ono osati zosakwana 28 μm imagwiritsidwa ntchito. Nthambi yapamwamba ya ultra-inc yopanda ndalama imasunga zothandizira, imathandizira kugwiritsa ntchito bwino, ndikuwonjezera magwiritsidwe ogwiritsa ntchito - kuwononga magwiridwe antchito, kupereka chiyembekezo pamsika.
Fufu la Flake Zinc lili ndi mawonekedwe a flake, ndipo amapangidwa ndi mphero yakukhotakhota kapena yamphamvu (PVD). Ili ndi gawo lalikulu la gawo lapamwamba (30-100), kufalikira kwabwino, kuphimba, ndi zotchinga katundu, ndipo zimagwiritsidwa ntchito makamaka mu zokutira za dacmet (zinc-aluminiyamu). Furket zinc Nkhumba limapereka bwino zojambula bwino, kuthekera koyandama, kuthekera kokhazikika, kuthekera kosakhazikika, komanso zolimbitsa thupi mosiyanasiyana poyerekeza ndi ufa wa sporrial zinc. Mu zofunda za dacmet, fumbi la flaket zitsulo limafalikira molunjika, ndikupanga zigawo zingapo zofananira ndi kulumikizana pamaso pa nkhope, kukonza mawonekedwe pakati pa zinzi ndi pakati pa zinc. Izi zimapangitsa kuti muoneke wokutira kwamphamvu, njira zochepetsera, njira zochepetsera zinnnnn zogwiritsidwa ntchito ndi makulidwe, ndikukulitsa zotchinga ndi anti-carris. Zovala za Anti-Corluon zopangidwa ndi fumbi lambiri limawonetsa bwino kwambiri kuposa zokutira zamagetsi kapena zoponyera zoponyera zowonongeka, zomwe zimachitika pamsonkhano wotsika, chilengedwe cha chilengedwe.
