3. Bishyizwe mubiranga ubuso:
4. Gutondekanya ukoresheje: ) Icyuma cyamashanyarazi (urupapuro rwicyuma cya silicon)
Isahani isanzwe ni impfunyapfunyo yicyuma gisanzwe cyubatswe.Ni icyiciro kinini cyibyuma, harimo: Q235, SS400, A36, SM400, St37-2, nibindi. Kubera amazina atandukanye yibihugu bitandukanye, ibipimo byashyizwe mubikorwa nabyo bitandukanye. Isahani isanzwe irimo amasahani azengurutswe hamwe namasahani ashyushye. Isahani ikonje isanzwe iri munsi ya 2mm mubyimbye; Isahani ishyushye 2mm-12mm
Urupapuro rwa Galvanised rwerekana urupapuro rwometseho urwego rwa zinc hejuru.Galvanizing nuburyo bwubukungu kandi bunoze bwo kurwanya ruswa bukoreshwa kenshi.Hafi ya kimwe cya kabiri cyumusaruro wa zinc kwisi ukoreshwa muriki gikorwa
(1) Imikorere
urupapuro rwicyuma ni ukurinda kwangirika hejuru yurupapuro rwicyuma no kongera igihe cyakazi.Ubuso bwurupapuro rwicyuma rushyizweho urwego rwa zinc metallic.Ubu bwoko bwicyuma cyitwa galvanised urupapuro rwitwa urupapuro rwicyuma.
(2)Ibyiciro
Irashobora kugabanywamo ibyiciro bikurikira ukurikije uburyo bwo gutunganya no gutunganya:
①Urupapuro rushyushye.Isahani yoroheje yinjizwa mu kigega cya zinc cyashongeshejwe, ku buryo isahani yoroheje ifite igipande cya zinc ifatirwa hejuru.Kugeza ubu, inzira ikomeza ya galvanizing ikoreshwa cyane cyane mubikorwa, ni ukuvuga, urupapuro ruzengurutswe ruhora rwinjizwa mu bwogero bwa galvanis hamwe na zinc yashongeshejwe kugirango rukore urupapuro rwicyuma;
②Urupapuro rwometseho ibyuma.Ubu bwoko bwicyuma nabwo bukorwa nuburyo bushyushye, ariko ako kanya nyuma yo kuva muri tank, burashyuha bugera kuri 500°C gukora firime ivanze ya zinc nicyuma.Ubu bwoko bwurupapuro rufite amabara meza hamwe no gusudira;
③Urupapuro rw'icyuma.Urupapuro rwicyuma rwakozwe nuburyo bwa electroplating rufite imikorere myiza.Nyamara, igifuniko cyoroshye, kandi kurwanya ruswa ntabwo ari byiza nkurupapuro rushyushye
④Uruhande rumwe kandi rufite impande zombi nabi.Urupapuro rumwe rukora urupapuro rwicyuma nigicuruzwa cyashyizwe kumurongo kuruhande rumwe gusa.Mu gusudira, gushushanya, kuvura anti-rust, gutunganya, nibindi, bifite imihindagurikire myiza kuruta impapuro zibiri.Kugirango tuneshe ibitagenda neza bya zinc zidafunze kuruhande rumwe, hariho ubundi bwoko bwurupapuro rwometseho uruzitiro rwometseho urwego ruto rwa zinc kurundi ruhande, ni ukuvuga impapuro ebyiri zitandukanye;
⑤Uruvange, rukomatanya urupapuro rwicyuma.Nibisahani yicyuma gikozwe muri zinc nibindi byuma nka gurş na zinc alloys ndetse no guhimba hamwe.Ubwoko bw'icyuma ntabwo bufite imikorere myiza yo kurwanya ingese gusa, ahubwo bufite imikorere myiza yo gutwikira;
Usibye ubwoko butanu bwavuzwe haruguru, hariho amabati yamabara yamashanyarazi, yacapishijwe impapuro zometseho ibyuma, polyvinyl chloride yamashanyarazi yamashanyarazi, nibindi. Ariko kuri ubu ikoreshwa cyane iracyari urupapuro rushyushye.
Isahani isize amabara, izwi kandi nk'icyuma cy'amabara, icyapa cy'amabara mu nganda.Isahani isize amabara ikozwe mubyuma bikonje bikonje hamwe na plaque yicyuma nka substrate, nyuma yo kwisuzumisha hejuru (gutesha agaciro, gukora isuku, kuvura imiti ihindura imiti), gusiga irangi muburyo bukomeza (uburyo bwo gutwikira roller), guteka no gukonjesha ibicuruzwa.
Isahani isize ibyuma ifite uburemere bworoshye, isura nziza kandi irwanya ruswa, kandi irashobora gutunganywa neza.Itanga ubwoko bushya bwibikoresho byinganda zubaka, inganda zubaka ubwato, inganda zikora ibinyabiziga, inganda zo mu nzu, n’inganda zikoresha amashanyarazi.Ibiti, kubaka neza, kuzigama ingufu, gukumira umwanda nizindi ngaruka nziza.
