Urupapuro 195
Ibisobanuro bigufi:
Isahani yicyuma isizwe hamwe nicyuma cya zinc hejuru yicyuma kugirango wirinde kwangirika hejuru yicyuma kandi ukongerera igihe cyo gukora.Ubu bwoko bwa plaque yamashanyarazi yitwa plaque ya plaque.
Irashobora kugabanywamo ibyiciro bikurikira ukurikije uburyo bwo gutunganya no gutunganya:
① Isahani ishyushye isahani yicyuma.Urupapuro rwicyuma rwinjizwa mu bwogero bwa zinc zashongeshejwe kugirango igice cya zinc gifatanye hejuru yacyo.Kugeza ubu, inzira ikomeza ya galvanizing ikoreshwa cyane cyane, ni ukuvuga, icyuma kizungurutswe gikomeza kwibizwa mu bwogero bwa zinc gushonga kugirango gikore icyuma cya galvanis;
Loy Urupapuro rwometseho ibyuma.Ubu bwoko bwicyuma nabwo bukozwe muburyo bushyushye, ariko bishyuha kugeza kuri 500 ℃ ako kanya nyuma yo kuva muri ruhago kugirango bakore firime ya zinc na fer.Urupapuro rwometseho rufite neza kandi rusudira;
Urupapuro rw'amashanyarazi.Urupapuro rwicyuma rwakozwe na electroplating rufite imikorere myiza.Nyamara, igipfundikizo ni gito kandi birwanya ruswa ntabwo ari byiza nkibishishwa bishyushye;
Side Uruhande rumwe rwometseho uruhande rumwe rukennye urupapuro rwicyuma.Uruhande rumwe rusize icyuma, ni ukuvuga ibicuruzwa biva kuruhande rumwe.Ifite imiterere ihindagurika kuruta impapuro ebyiri zometseho gusudira, gutwikira, kuvura antirust no kuyitunganya.Kugirango tuneshe imbogamizi zo kudashyira zinc kuruhande rumwe, hariho ubundi bwoko bwurupapuro rwometseho uruzitiro ruto rwa zinc kurundi ruhande, ni ukuvuga urupapuro rwumukene rwimpande ebyiri;
Oy Amashanyarazi, akomatanya urupapuro rwicyuma.Nibisigazwa bikozwe muri zinc nibindi byuma nka aluminium, gurş na zinc, ndetse nibyuma bisobekeranye.Ubu bwoko bw'icyuma ntabwo bufite imikorere myiza ya antirust gusa, ahubwo bufite imikorere myiza yo gutwikira;
