Ibyiciro bya galvanised

Galvanizing bivuga tekinoroji yo kuvura hejuru yo gushiraho igipande cya zinc hejuru yicyuma, ibivanze cyangwa ibindi bikoresho kugirango bigire ingaruka nziza zo gukumira ubwiza nubwiza.Uburyo bukoreshwa bukoreshwa ni galvanizasi ishyushye.

Zinc irashobora gushonga byoroshye muri acide kimwe na alkali, bityo yitwa icyuma cyitwa amphotropique. Zinc ihinduka bike cyane mumyuka yumutse.Mu kirere cyumuyaga, firime ya alkaline zinc karubone ikorwa hejuru ya zinc.Mu dioxyde de sulfure, hydrogène sulfide hamwe n’ikirere cya Marine, kurwanya zinc birwanya ubukana, cyane cyane mubushyuhe bwo hejuru nubushuhe bwinshi burimo umwuka wa aside aside, gutwika zinc biroroshye kubora. Ubushobozi busanzwe bwa electrode ya zinc ni-0,76V, kuri materique yicyuma, coinc ya zinc ni iyikoreshwa rya anodic, ikoreshwa cyane cyane mukurinda kwangirika kwicyuma, imikorere yayo yo gukingira hamwe nubunini bwa coating bifitanye isano rya bugufi. kuvura passivation, gusiga cyangwa gutwikirwa hamwe nuburinzi bwumucyo, birashobora kunoza cyane kurinda no gushushanya.

 Ubukonje bukabije

Ubukonje bukonje, nabwo bwitwa electrogalvanizing, ni ugukoresha ibikoresho bya electrolytike nyuma yamavuta, gutoragura, umunyu wa zinc mubisubizo, no guhuza electrode mbi yibikoresho bya electrolytike, muburyo butandukanye na plaque ya zinc, ihujwe na electrode nziza ya electrolytike. imbaraga z'ibikoresho, ukoresheje umuyoboro uva mubyiza ukajya mubi uzashyira igipande cya zinc kumuyoboro, umuyoboro wa plaque ukonje ubanza gutunganywa nyuma yo gusya.

Imashini yashizwemo

Mu ngoma izunguruka ifite isahani, umupira wikirahure, ifu ya zinc, amazi na porotokoro, umupira wikirahure nkibikoresho bigenda bizunguruka hamwe ningoma, guterana hamwe ninyundo hejuru yisahani bitanga ingufu zumubiri.Mubikorwa bya porotokoro ya chimique, ifu ya zinc isize "gusudira gukonje" hejuru yububiko, ikora igipande cyoroshye, kimwe kandi kirambuye hamwe nubunini runaka.

Ashyushye

Uburyo nyamukuru bwicyuma hejuru yicyuma ni ubushyuhe-bushyushye.

Amashanyarazi ashyushye yatejwe imbere muburyo bukera kandi afite imyaka ijana na mirongo irindwi kuva yakoreshwa mu nganda mu 1836. Nyamara, inganda zishyushye zashyizwe imbere ku rugero runini hamwe n’iterambere ryihuse ry’ibyuma bikonje bikonje. mu myaka mirongo itatu ishize.

Igikorwa cyo gukora isahani ishyushye cyane kirimo: isahani yumwimerere ibanziriza isahani ishyushye nyuma yo kuvurwa yarangije kugenzurwa ibicuruzwa, nibindi. Ukurikije akamenyero, ukurikije uburyo butandukanye bwo kuvura amasahani, uburyo bwo gushyushya amashyanyarazi bugabanijwemo umurongo wo hanze na annealing imbere kumurongo annealing.
