1. Kurwanya ingese cyane
Intego nyamukuru yo gushyiramo amashanyarazi mu byuma binini ni uguhagarika ingese mu nzira zayo—kandi niho urwego rwa zinc oxide ku byuma binini rugaragara. Dore uko bikora: irangi rya zinc ribanza kwangirika, rigafata icyuma kiri munsi yacyo kugira ngo kigume gihagaze igihe kirekire. Iyo hatabayeho iyi nganzo ya zinc, icyuma cyaba gikunze kwangirika cyane, kandi guhura n’imvura, ubushuhe, cyangwa ibindi bintu karemano byakwihutisha kwangirika.
2. Igihe kirekire cyo kubaho
Ubu burambe buturuka ku irangi ririnda. Ubushakashatsi bwerekana ko, mu bihe bisanzwe, ibyuma bya galvanised bikoreshwa mu nganda bishobora kumara imyaka 50. Ndetse no mu bidukikije byangiza cyane—urugero nk'ahantu hari amazi menshi cyangwa ubushuhe bwinshi—bishobora kumara imyaka 20 cyangwa irenga.
3. Imiterere myiza y'ubwiza
Abantu benshi bemeranya ko icyuma gikozwe mu mabati gifite isura nziza kurusha izindi mashini nyinshi zikozwe mu byuma. Ubuso bwacyo bukunze kuba bwiza kandi busukuye, bigatuma gisa neza.
Aho Ibyuma bya Galvanized Bikoreshwa
Uburyo butandukanye bushobora gukoreshwa mu gukurura ibyuma:
2. Gukoresha amashanyarazi mu gukwirakwiza amashanyarazi
3. Gukwirakwira kwa zinki
4. Gutera icyuma
Ishyushye cyane
Mu gihe cyo gushyiramo galvanizing, icyuma cyinjizwa mu bwogero bwa zinc bushongeshejwe. Gushyiramo galvanizing ishyushye (HDG) bikubiyemo intambwe eshatu z'ibanze: gutegura ubuso, gushyiramo galvanizing, no kugenzura.
Gutegura ubuso
Mu gutegura ubuso, icyuma cyakozwe mbere cyoherezwa mu gukaraba ibyuma kandi gikorerwa mu byiciro bitatu byo gusukura: gukuraho amavuta, gukaraba aside no kuvanga. Hatabayeho ubu buryo bwo gusukura, gukaraba ibyuma ntibishobora gukomeza kuko zinc idashobora gukorana n'icyuma cyanduye.
Gutunganya ibyuma
Nyuma yo gutegura ubuso, icyuma cyinjizwa muri 98% ya zinc ishongeshejwe kuri 830°F. Inguni icyuma cyinjizwamo mu nkono igomba gutuma umwuka usohoka mu miterere y'utubumbe cyangwa mu yindi mifuka. Ibi kandi bituma zinc inyura no mu mubiri wose w'icyuma. Muri ubwo buryo, zinc ihura n'icyuma cyose. Icyuma kiri imbere mu cyuma gitangira gukorana na zinc, kigakora irangi rya zinc-iron intermetallic. Ku ruhande rwo hanze, hashyirwamo irangi rya zinc ryuzuye.
Igenzura
Intambwe ya nyuma ni ukugenzura igipfundikizo. Hakorwa igenzura rigaragara kugira ngo harebwe ahantu hose hatarapfundikijwe ku gice cy'icyuma, kuko igipfundikizo kitazafatana n'icyuma cyanduye. Igipimo cy'ubunini bwa magnetique gishobora kandi gukoreshwa kugira ngo hamenyekane ubunini bw'igipfundikizo.
2 Gukoresha amashanyarazi mu gukwirakwiza amashanyarazi
Icyuma gikozwe mu buryo bwa elegitoroniki gikorwa binyuze mu buryo bwa elegitoroniki. Muri ubu buryo, icyuma cyinjizwa mu bwogero bwa zinc, hanyuma amashanyarazi akanyuzwamo. Ubu buryo buzwi kandi nka electroplating.
Mbere yo gukoresha electrogalvanizing, icyuma kigomba gusukurwa. Aha, zinc ikora nk'anode yo kurinda icyuma. Kuri electrolysis, zinc sulfate cyangwa zinc cyanide ikoreshwa nk'electrolyte, mu gihe cathode irinda icyuma kwangirika. Iyi electrolyte ituma zinc iguma ku buso bw'icyuma nk'igitambaro. Uko icyuma kimara igihe kinini cyinjijwe mu bwogero bwa zinc, niko igitambaro kirushaho kuba kinini.
Kugira ngo hongerwe uburyo bwo kurwanya ingese, hari uburyo bwo guhindura imiterere y’ibintu bugira akamaro kanini. Ubu buryo butanga urwego rw’inyongera rwa zinc na chromium hydroxide, bigatuma icyuma gisa n’ubururu.
3 Kwinjira kwa Zinc
Gushyira zinc kuri zinc bikubiyemo gukora irangi rya zinc ku buso bw'icyuma cyangwa icyuma kugira ngo hirindwe ingese y'icyuma.
Muri ubu buryo, icyuma gishyirwa mu kintu kirimo zinc, hanyuma kigafungwa kigashyuha kugeza ku bushyuhe buri munsi y’aho zinc ishongera. Ingaruka z’iki gikorwa ni ukurema ibumba rya zinc-iron, hamwe n’urukuta rukomeye rwa zinc isanzwe ifata ku buso bw’icyuma kandi igatanga ubudahangarwa bukomeye bwo kwangirika. Iki gipfundikizo kandi cyoroshya gufatana neza kw’irangi ku buso.
Ku bintu bito by'icyuma, gutwikira zinc ni bwo buryo bwiza. Ubu buryo bukwiriye cyane cyane ibice by'icyuma bifite imiterere idasanzwe, kuko urwego rwo hanze rushobora gukurikiza byoroshye igishushanyo cy'icyuma cy'ibanze.
4 Gutera icyuma
Mu gikorwa cyo gutera zinc mu cyuma, uduce twa zinc twashongeshejwe dukoresha amashanyarazi cyangwa atome duterwa hejuru y'icyuma. Iki gikorwa gikoreshwa hakoreshejwe imbunda ikoresha intoki cyangwa umuriro wihariye.
Mbere yo gukoresha zinc packaging, imyanda yose, nk'iy'ubuso budakenewe, amavuta, n'ingese, igomba gukurwaho. Nyuma yo gusukura, uduce twa zinc twashongeshejwe dushyirwa ku buso buto, aho dukomera.
Ubu buryo bwo gusiga icyuma ni bwo bwiza cyane mu gukumira gushwanyagurika no gucika, ariko si bwiza mu gutanga ubudahangarwa bukomeye bwo kwangirika.
Igishishwa cya zinc kimara igihe kingana iki?
Ku bijyanye no kuramba, akenshi biterwa n'ubugari bw'igitambaro cya zinc, ndetse n'ibindi bintu nk'ubwoko bw'ibidukikije, ubwoko bw'igitambaro cya zinc gikoreshwa, n'ubwiza bw'igitambaro cya zinc cyangwa spray. Uko igitambaro cya zinc kiba kinini, niko kiramba.
Gukoresha galvanizing ishyushye ugereranije no gukoresha galvanizing ikonjeImyambaro ishyushye ikoreshwa mu gukaraba muri rusange iramba kurusha iy'icyuma gikonje kuko akenshi iba ikomeye kandi ikomeye. Gukaraba muri icyuma bikoresha gukaraba muri zinc ishongeshejwe, mu gihe mu buryo bwo gukaraba muri galvanizing ikonje, urwego rumwe cyangwa ebyiri ziterwaho cyangwa zigasigwaho amavuta.
Ku bijyanye no kuramba, irangi rishyushye rishobora kumara imyaka irenga 50 hatitawe ku miterere y'ibidukikije. Mu buryo bunyuranye, irangi rishyushye rikunze kumara amezi make kugeza ku myaka mike, bitewe n'ubunini bw'irangi.
Byongeye kandi, mu bidukikije byangiza cyane nko mu nganda, igihe cyo kumaraho irangi rya zinc gishobora kuba gito. Kubwibyo, guhitamo irangi rya zinc ryiza no kurigumana mu gihe kirekire ni ingenzi cyane mu kurinda ingese, kwangirika no kwangirika.
