Ashyushye cyanenuburyo bukoreshwa cyane mukurinda ibyuma nicyuma kubora. Iyi nzira ikubiyemo kwibiza icyuma mu bwogero bwa zinc yashongeshejwe, ikora igifuniko gikomeye, kirinda. Ibyuma bivamo galvaniside birwanya cyane ingese kandi birashobora kwihanganira ibidukikije bibi. Ariko, kugera kubisubizo byiza bisaba kubahiriza ibisabwa byihariye nibikorwa byiza. Iyi ngingo iracengera mubisabwa byingenzi kugirango bishyushye-bishyushye kugirango habeho ibisubizo byiza kandi biramba.
1. Guhitamo Ibikoresho
Icyambere gisabwa kugirango hot-dip galvanizing ni uguhitamo ibikoresho bikwiye. Ntabwo ibyuma byose bikwiranye niki gikorwa. Mubisanzwe, ibyuma nicyuma nabakandida bambere. Ibigize ibyuma birashobora kugira ingaruka zikomeye kumiterere yagalvanizing. Kurugero, kuba hari ibintu nka silikoni na fosifore mubyuma birashobora guhindura umubyimba no kugaragara kwa zinc. Kubwibyo, ni ngombwa guhitamo ibikoresho bifite igenzurwa kandi bizwi kugirango ugere kubisubizo bihamye.
2. Gutegura Ubuso
Gutegura Ubuso ni intambwe ikomeye murigushyuhainzira. Ubuso bw'icyuma bugomba kuba busukuye kandi butarimo umwanda nk'amavuta, amavuta, ingese, n'ubunini bw'urusyo. Umwanda uwo ariwo wose urashobora kubuza zinc gukomera neza, biganisha ku bwiza bubi. Gutegura ubuso mubisanzwe birimo ibyiciro bitatu:
- Gutesha agaciro: Kurandura umwanda kama ukoresheje ibisubizo bya alkaline cyangwa umusemburo.
- Gutoragura: Kurandura ingese nubunini ukoresheje ibisubizo bya acide, mubisanzwe hydrochloric cyangwa acide sulfurike.
- Fluxing: Gukoresha igisubizo cya flux, akenshi zinc ammonium chloride, kugirango wirinde okiside mbere yo kwibizwa muri zinc yashonze.
Gutegura neza neza bituma habaho isano ikomeye hagati yicyuma na zinc, bikongerera igihe kirekire ningirakamaro ya galvanizing.
3. Ibigize ubwogero n'ubushyuhe
Ibigize hamwe nubushyuhe bwo kwiyuhagira zinc nibintu byingenzi mubikorwa bishyushye. Kwiyuhagira kwa zinc bigomba kuba byibuze byibuze 98% bya zinc nziza, hamwe nijanisha risigaye rigizwe nibintu nka aluminium, gurş, na antimoni kugirango bitezimbere imiterere. Ubushyuhe bwo kwiyuhagira buri hagati ya 820 ° F na 860 ° F (438 ° C kugeza 460 ° C). Kugumana ubushyuhe bukwiye ningirakamaro kugirango ugere ku kintu kimwe kandi cyiza. Gutandukana birashobora kuvamo inenge nkubunini butaringaniye, gufatana nabi, hamwe nubuso bukabije.
4. Igihe cyo kwibiza
Igihe cyo kwibiza mu bwogero bwa zinc ni ikindi kintu gikomeye. Biterwa nubunini nubunini bwaicyuma kirimo imbaraga. Mubisanzwe, icyuma cyinjizwa kugeza kigeze ku bushyuhe bwogero, bigatuma zinc ikora umuringa wibyuma. Kwibiza cyane birashobora gutuma habaho umubyimba ukabije, mugihe kwibiza munsi bishobora kuvamo uburinzi budahagije. Kubwibyo, kugenzura neza igihe cyo kwibiza birakenewe kugirango ugere ku mubyimba wifuzwa.
5. Ubuvuzi bwa nyuma ya Galvanizing
Nyuma yicyuma kimaze gukurwa kurizinc, ikorerwa nyuma ya galvanizing kugirango yongere imitungo. Ubu buvuzi bushobora kubamo kuzimya amazi cyangwa gukonjesha ikirere kugirango ushimangire zinc vuba. Byongeye kandi, uburyo bwo kuvura passivation burashobora gukoreshwa kugirango hirindwe ingese yera, ubwoko bwa ruswa ishobora kugaragara hejuru yubushyuhe bushya. Gufata neza no kubika ibikoresho bya galvanis na byo ni ngombwa kugirango uburinganire bwuzuye.
6. Kugenzura no kugenzura ubuziranenge
Hanyuma, kugenzura neza no kugenzura ubuziranenge nibyingenzi kugirango tumenye intsinzi yagushyuhainzira. Ubugenzuzi busanzwe bukubiyemo isuzuma ryerekanwa, gupima ubunini, hamwe n'ibizamini bya adhesion. Ibipimo nka ASTM A123 / A123M bitanga umurongo ngenderwaho wuburinganire bwemewe nubuziranenge. Gukurikiza aya mahame byemeza ko ibicuruzwa biva mu mahanga byujuje ibyangombwa bisabwa kandi bigatanga uburinzi burambye bwo kwirinda ruswa.
Umwanzuro
Gallvanizing ishyushye nuburyo bwiza bwo kurinda ibyuma nicyuma kwangirika, ariko bisaba kwitondera neza birambuye no kubahiriza ibisabwa byihariye. Kuva guhitamo ibikoresho no gutegura hejuru kugeza kwiyuhagira, igihe cyo kwibiza, hamwe nubuvuzi bwa nyuma ya galvanis, buri ntambwe igira uruhare runini mugushikira ibipimo byiza kandi biramba. Mugukurikiza ibyo byiza byiza no gukomeza kugenzura ubuziranenge bukomeye, ababikora barashobora kwemeza ko ibicuruzwa byabo byashyizwe ahagaragara bitanga imikorere myiza no kuramba.
