Mugihe cyo gushiraho no gushiraho urubuga rwubatswe rwo gusya ibyuma, bikunze kugaragara ko imiyoboro cyangwa ibikoresho bigomba kunyura murigusyaihagaritse. Kugirango ushoboze ibikoresho byumuyoboro kunyura kuri platifomu neza, mubisanzwe birakenewe kumenya ahantu hamwe nubunini bwafunguye mugihe cyogushushanya, kandi uruganda rukora ibyuma ruzakora ibicuruzwa byabigenewe. Inzira yumusaruro wabigenewe ubanza bisaba itumanaho ryinshi no guhanahana amakuru hagati yishami rishinzwe gushushanya ibyuma n’ishami rishinzwe imiterere y’ibyuma, abatanga ibikoresho n’ishami rishinzwe ubushakashatsi no gushushanya. Bitewe nibintu byinshi bifitanye isano birimo, hariho ukutamenya neza mubunini n'umwanya wibikoresho bigezweho. Mugihe cyo kwishyiriraho, akenshi birashoboka ko umwobo wabigenewe udashobora guhaza ibikenewe kurubuga. Urebye uko ibintu bimeze, kugirango harebwe igipimo cy’umusaruro w’ibyuma no kunoza igishushanyo mbonera n’umusaruro w’ibyuma by’ibyuma, mu buryo bugezweho bwo gutunganya no kubyaza umusaruro, muri rusange, muri rusange, imyobo imwe ifite diameter ntoya igoye kuyimenya ntabwo ikoreshwa kandi ikanatunganywa, ariko igasimbuzwa uburyo bwo gutunganya bwa kabiri nko gufungura aho hantu, gukata, gusudira, no gusya ukurikije uko ibintu bimeze ubu mu gihe cyo gushiraho no kubaka ibyuma.
Nkibikoresho bishya, ibyuma bisya ibyuma bikoreshwa cyane. Galvanizing yabaye uburyo bwingenzi bwo kurwanya ruswa kubwibyuma, atari ukubera ko zinc ishobora gukora urwego rukingira hejuru yicyuma, ariko nanone kubera ko zinc ifite ingaruka zo kurinda catodiki. Iyo ibyuma bisya ibyuma byajyanwe kurubuga, gutunganya kabiri no gusudira rimwe na rimwe bisabwa kugirango bishyirwemo. Kubaho kwa zinc bizana ingorane zimwe na zimwe zo gusudira ibyuma bisya.
Isesengura ryo gusudira kwicyuma cya galvanised
Ibyuma bya galvanised byometseho icyuma cya zinc hejuru yicyuma hejuru yicyuma kugirango wirinde kwangirika hejuru yicyuma kandi cyongerera igihe cyo gukora. Ubuso bw'icyuma gisya buzaba bumeze nk'indabyo. Ukurikije uburyo bwo gukora no gutunganya, birashobora kugabanywamo ibyiciro bikurikira: et urupapuro rushyushye; Urupapuro rw'amashanyarazi. Ingingo yo gushonga ya zinc ni 419 ℃ naho guteka ni 907 ℃, biri munsi cyane yo gushonga ibyuma, 1500 ℃. Kubwibyo, mugihe cyo gusudira, urwego rwa galvanised rwabanje gushonga ibikoresho byababyeyi. Nyuma yisesengura ryavuzwe haruguru, imiterere nubukorikori bwurupapuro rwa galvanisme ni nkibya shitingi isanzwe ya karubone. Itandukaniro gusa nuko hariho igifuniko cya zinc hejuru yicyuma gisya. Uburyo bwo gusudira bwo gusya ibyuma
(1) Intoki arc gusudira
Kugirango ugabanye umwotsi wo gusudira no gukumira ibisekuru byo gusudira hamwe nu byobo, urwego rwa zinc hafi ya ruhago rugomba kuvaho mbere yo gusudira. Uburyo bwo kuvanaho bushobora kuba flame guteka cyangwa kumusenyi. Ihame ryo guhitamo inkoni zo gusudira ni uko imiterere yubukanishi bwicyuma gisudira igomba kuba yegereye ibishoboka byose kubabyeyi, kandi ibirimo silikoni mubikoresho byo gusudira buri munsi byuma byashongeshejwe bigomba kugenzurwa munsi ya 0.2%. Kubyuma bya karuboni nkeya indorerwamo zinc ibyuma, J421 / 422 cyangwa J423 yo gusudira bigomba kubanza gukoreshwa. Mugihe cyo gusudira, gerageza ukoreshe arc ngufi kandi ntugahindure arc kugirango wirinde kwaguka kwagace kashongeshejwe murwego rwa galvanise, urebe neza ko ruswa irwanya igihangano kandi ugabanye umwotsi.
(2) Gusudira ibyuma arc
Koresha imyuka ya gaze ya CO2 cyangwa gusudira gaze ikingiwe gusudira nka Ar + CO2, Ar + 02 kugirango usudire. Gazi ikingira igira ingaruka zikomeye kubintu bya Zn muri weld. Iyo hakoreshejwe CO2 cyangwa CO2 + 02, ibikubiye muri Zn muri weld iba hejuru, mugihe iyo Ar + CO2 cyangwa Ar + 02 ikoreshwa, ibirimo Zn muri weld biri hasi. Ibiriho bifite ingaruka nke kubintu bya Zn muri weld. Mugihe cyo gusudira cyiyongera, ibirimo Zn muri weld bigabanuka gato. Iyo ukoresheje gusudira gaze ikingira gusudira ibyuma bisya ibyuma, umwotsi wo gusudira ni munini cyane ugereranije nu gusudira intoki, bityo rero hakwiye kwitabwaho cyane kugirango umunaniro. Ibintu bigira ingaruka kumubare hamwe nibigize umwotsi cyane cyane ibyubu na gaze ikingira. Ninini nini, cyangwa nini ya CO2 cyangwa O2 muri gaze ikingira, nini nini yo gusudira, hamwe na ZnO mubyuka nabyo biriyongera. Umubare ntarengwa wa ZnO urashobora kugera kuri 70%. Mubisobanuro bimwe byo gusudira, ubujyakuzimu bwinjira mubyuma bya galvaniseri biruta ibyo gusya ibyuma.
