Galvanised
Urupapuro rwometseho Zinc rwagura ubuzima bwibicuruzwa kandi rufasha kwirinda kwangirika.Hamwe nubushyuhe bwinshi kandi bugaragara neza, nibyiza mukubaka inyubako zinganda, silos, ibigega, mubindi bikorwa.umusanzu wo kwerekana ubushyuhe.
Urupapuro
Urupapuro rw'urukiramende rwometseho urukiramende rufite imbaraga nyinshi zo kurwanya ruswa, nibyiza byo kubaka ibisenge hamwe nu ruganda.Hamwe nubuzima burebure bwingirakamaro, birwanya ibidukikije kandi
Galvanizing nuburyo bwubukungu kandi bunoze bwo kwirinda kwangirika kwicyuma, kandi ubunini bwibyuma bya galvanis muri rusange ni 0.35 kugeza 3 mm.Icyongereza "galvanizing" bivuze ko urwego rwa galvanised rushobora kurinda amashanyarazi icyuma.Mu 1742, Umufaransa Meloman (Melomin) yize neza uburyo bushyushye bwa galvaniza.Mu 1836, Sorel y'Abafaransa (Sorel) yakoresheje uburyo bwa hot-dip galvanizing mu nganda.Mu 1837, HW Grawford yabonye ipatanti yo gushyushya ibishishwa hakoreshejwe flux.Mu 1935, Umunyamerika Sendzimir (T. Sendzimir) yasabye ko hakoreshwa uburyo bwo kugabanya gazi yo gukingira kugira ngo ikomeze gushyushya ibyuma bikabije, bizwi ku izina rya "Uburyo bwa Sendzimir".Mu 1937, muri Amerika hubatswe umurongo wa mbere wa Sendzimir ukomeje gushyuha.Ubushinwa bwatangiye gukora amashyanyarazi ashyushye muri Anshan mu myaka ya za 1940, naho mu 1979, hubatswe umurongo wa mbere uhoraho wa hot-dip galvanizing wibyuma bya Wuhan。
Kwibira bishyushye
Hariho ubwoko bubiri bwubushyuhe-dip uburyo bwo gukoresha amashanyarazi.Ubunini bwubushyuhe bwa dip zinc ni 60 ~ 300g / m2 (uruhande rumwe), bukoreshwa mubice bisaba kurwanya ruswa ikomeye.Amashanyarazi ya zinc ni 10-50g / m2 (uruhande rumwe), ikoreshwa cyane mubice bisize irangi cyangwa ibice bidafite irangi bidasaba kwihanganira ruswa.Uburyo bushyushye bugabanijwe muburyo bwa flux nuburyo bwo kugabanya gazi ikingira uburyo bwo kwitegura.Uburyo bwa flux nugutoragura icyuma gifatanye kugirango ukureho okiside hejuru, hanyuma unyure mumatungo arimo ZnCl2 na NH4Cl, hanyuma winjire mumatara ya zinc yashongeshejwe kugirango uhindurwe.Uburyo bwo kugabanya gazi yo gukingira bukoreshwa cyane muburyo bukomeza bushyushye bwa galvaniza yicyuma.Icyuma cya strip kibanza kunyura mu itanura rishyushye ryaka kugirango ritwike amavuta asigaye hejuru, kandi icyarimwe, hakozwe firime ya oxyde de fer;Sponge Iron.Nyuma yicyuma cya strip gifite isuku kandi kigakonjeshwa gikonje kugeza ku bushyuhe burenze gato ubw'icyuma gishongeshejwe, cyinjira mu nkono ya zinc kuri 450-460 ° C, kandi kigakoresha icyuma cyo mu kirere kugira ngo kigenzure ubunini bw’urwego rwa zinc.Hanyuma, iranyuze hamwe na chromate igisubizo kugirango irusheho kurwanya ingese.
Amashanyarazi
Ukurikije igisubizo cya plaque yakoreshejwe, irashobora kugabanywa muburyo bwa alkaline nuburyo bwa aside.Igisubizo cya alkaline gifite igiciro cyinshi, cyangiza ibidukikije, umusaruro muke, hamwe nubwiza buke, kubwibyo ntabwo bikoreshwa.Ibice byingenzi bigize acide ya acide ni ZnSO4 · 7H2O, NH4Cl na Al2 (SO4) 3 · 18H2O, nibindi. muri Zn2 + mubisubizo bya plaque, hanyuma Zn2 + igabanuka kuri zinc metallic kuri cathode igashyirwa hejuru yicyuma.Igipfundikizo kivurwa hamwe nigisubizo kivanze cya fosifate na chromate, gishobora kunoza irangi, kandi hejuru yurupapuro rwicyuma cya electro-galvanised irasa kandi yoroshye, yakoreshwaga cyane mubikorwa byimodoka kera.Mu myaka yashize, uburyo bwo gukoresha bwaguwe mu nganda z’amashanyarazi n’ibindi bintu, byateje imbere iterambere ry’inganda zikoresha amashanyarazi.Mu myaka ya za 70, impapuro zakozweho uruhande rumwe.
