Isesengura ryuburyo bwo gutunganya ibyuma byo gusya ibyuma mbere yo gushushanya

Gushyushya ubushyuhe-bushyushye (bushyushye-bugufi bugufi) hejuru yicyuma cya tekinoroji nicyuma gikoreshwa cyane kandi cyiza cyo kurinda ubuso bwo kugenzura kwangirika kw ibidukikije byibyuma. Muri rusange ibidukikije byikirere, igishishwa gishyushye cya galvanizing cyabonetse nubu buhanga kirashobora kurinda ibice byibyuma kutangirika imyaka myinshi cyangwa imyaka irenga 10. Kubice bidafite ibisabwa byihariye byo kurwanya ruswa, ntabwo hakenewe ubuvuzi bwa kabiri bwo kurwanya ruswa (gutera cyangwa gushushanya). Ariko rero, kugirango uzigame amafaranga yimikorere yibikoresho nibikoresho, kugabanya kubungabunga, no kurushaho kongera igihe cyumurimo wo gusya ibyuma mu bidukikije bikaze, akenshi birakenewe ko ukingira icyiciro cya kabiri kumashanyarazi ashyushye cyane, ni ukuvuga, gushyiramo impeshyi kama yizuba hejuru yubushyuhe bukabije kugirango habeho sisitemu yo kurwanya ruswa.
Mubisanzwe, ibyuma byibyuma mubisanzwe bitambuka kumurongo ako kanya nyuma yo gushyuha. Mugihe cya passivation, reaction ya okiside ibaho hejuru yubushyuhe bwa dip-galvanizing hamwe nubuso bwumuti wa passivation, bigakora firime yuzuye kandi ifatanye neza hejuru yubushyuhe bwa dip-galvanizing, igira uruhare mukuzamura ruswa irwanya ruswa. Nyamara, kubintu byibyuma bigomba gushyirwaho primer yo mucyi kugirango habeho uburyo bubiri bwo kurwanya ruswa kugirango burinde, firime yuzuye, yoroshye, kandi yoroheje ya passiyo ya passiyo igoye guhuza cyane na primer yo mu cyi cyakurikiyeho, bikaviramo kubyimba imburagihe no kumeneka kwifumbire mvaruganda mugihe cya serivisi, bikagira ingaruka kubirinda.
Kugirango turusheho kunoza uburyo burambye bwibyuma bivangwa na hot-dip galvanizing, mubisanzwe birashoboka gutwikira ibinyabuzima bikwiranye nubutaka bwabyo kugirango habeho uburyo bwo gukingira. Urebye ko ubuso bwa hot-dip ya galvanised ya gati ya feri iringaniye, yoroshye, kandi imeze nk'inzogera, imbaraga zo guhuza hagati yazo na sisitemu yo gutwikira nyuma ntizihagije, zishobora gutuma habaho kubyimba, kumeneka, no kunanirwa hakiri kare. Muguhitamo primer ikwiye cyangwa uburyo bukwiye bwo kwitegura, imbaraga zo guhuza hagati ya zinc coating / primer coating zirashobora kunozwa, kandi ingaruka ndende zo gukingira sisitemu yo gukingira irashobora gukoreshwa.
Tekinoroji yingenzi igira ingaruka kumurinzi wa hot-dip galvanised ibyuma bifata sisitemu yo gukingira kandi nuburyo bwo kuvura mbere yo gutwikira. Sandblasting ni bumwe muburyo bukoreshwa cyane kandi bwizewe bwo gutunganya ibyuma byo gusya ibyuma, ariko kubera ko ubushyuhe bwa dip-galvanised busa bworoshye, umuvuduko ukabije wumusenyi hamwe nubunini bwumucanga bishobora gutera igihombo cyurwego rwicyuma. Mugucunga umuvuduko wa spray nubunini bwumucanga, gutondekanya umucanga uringaniye hejuru yubushyuhe bwa dip-galvanised ibyuma ni uburyo bwiza bwo kuvura hejuru, bufite ingaruka zishimishije kumyerekano ya primer, kandi imbaraga zo guhuza hagati yazo na hot-dip zishyushye zirenze 5MPa.
Ukoresheje cyclic hydrogène primer irimo fosifate ya zinc, gufatana hagati ya zinc coating / primer organic primer birenze cyane 5MPa nta mucanga. Kubuso bwa hot-dip ya galvanised ibyuma bifata ibyuma, mugihe bitari byoroshye gukoresha imiti yo gutunganya umucanga, mugihe harebwa ubundi buryo bwo gutwika ibinyabuzima nyuma, hashobora gutorwa primer irimo fosifate, kubera ko fosifate muri primer ifasha kunoza ifatizo rya firime irangi no kongera ingaruka zo kurwanya ruswa.
Mbere yuko primer ikoreshwa mubwubatsi bwa coating, igishyushye gishyushye cya galvanizike yicyuma gifata ibyuma nticyoroshye. Kwiyitirira nta ngaruka nini bigira mu kunoza imiterere, kandi guhanagura inzoga nta ngaruka zigaragara zigira ku mbaraga zihuza hagati ya zinc coating / primer.
