Gallvanizing ishyushye nimwe muburyo bwingenzi bwo kurwanya ruswa ikoreshwa muburyo bwo kuvura ibyuma. Mubidukikije byangirika, ubunini bwikigero cya galvanised ya feri yicyuma bigira ingaruka itaziguye mukurwanya ruswa. Muburyo bumwe bwo guhuza imbaraga, ubunini bwikibiriti (urugero rwa adhesion) buratandukanye, kandi igihe cyo kurwanya ruswa nacyo kiratandukanye. Zinc ifite imikorere myiza cyane nkibikoresho birinda ibyuma bifata ibyuma. Ubushobozi bwa electrode ya zinc iri munsi yicyuma. Imbere ya electrolyte, zinc ihinduka anode ikabura electron kandi ikabora cyane, mugihe ibyuma byo gusya ibyuma bihinduka cathode. Irinzwe kwangirika no gukingira amashanyarazi kurinda igorofa. Ikigaragara ni uko igipfundikizo cyoroshye, igihe kigufi cyo kurwanya ruswa, nigihe cyo kurwanya ruswa cyiyongera uko umubyimba wiyongera. Ariko, niba umubyimba wububiko ari mwinshi cyane, imbaraga zo guhuza hagati yigitereko nicyuma cya substrate zizagabanuka cyane, bizagabanya igihe cyo kurwanya ruswa kandi ntabwo bikoresha amafaranga mubukungu. Kubwibyo, hari agaciro keza kubwububiko, kandi ntabwo ari byiza kuba mwinshi. Nyuma yisesengura, kubintu bishyushye-byashizwemo ibyuma bisya ibice bitandukanye, uburebure bwiza bwo gutwikira burakwiriye cyane kugirango ugere igihe kirekire cyo kurwanya ruswa.
Inzira zo kunoza umubyimba
1. Hitamo ubushyuhe bwiza bwa galvanizing
Nigute ushobora kugenzura ubushyuhe bwa galvanizing yo gusya ibyuma nibyingenzi kugirango tumenye kandi tunoze ubwiza bwa coating. Nyuma yimyaka yimyitozo yumusaruro, twizera ko ari byiza kugenzura ubushyuhe bwa dip-galvanizing kuri 470 ~ 480 ℃. Iyo umubyimba wigice cyashizweho ari 5mm, uburebure bwa coating ni 90 ~ 95um (ubushyuhe bwibidukikije ni 21 ~ 25 (). Muri iki gihe, ibyuma bishyushye bishyushye bigeragezwa nuburyo bwa sulfate y'umuringa. Ibisubizo byerekana ko: igipfundikizo cyinjijwe inshuro zirenga 7 utagaragaje materique yicyuma; 455 ~ 460 ℃, uburebure bwa coating bwarenze agaciro keza Muri iki gihe, nubwo ibisubizo byuburinganire bwa coating ari byiza (mubisanzwe byinjijwe inshuro zirenga 8 uterekanye matrix), bitewe nubwiyongere bwamazi ya zinc, ibintu byo kugabanuka ntibigaragara neza, ndetse nubusembwa nkubushuhe bwa 5 munsi ya 60um) Umubare ntarengwa wo gupima uburinganire ni 4 kwibiza kugirango ugaragaze matrix, kandi kurwanya ruswa ntabwo byemewe.
2. Kugenzura umuvuduko wo guterura ibice byashizweho. Umuvuduko wo guterura ibyuma bisya ibyuma biva mumazi ya zinc bigira uruhare runini mububyimba. Iyo umuvuduko wo guterura wihuta, noneho Igice cya galvanised ni kinini. Niba umuvuduko wo guterura utinze, igifuniko kizaba gito. Kubwibyo, umuvuduko wo guterura ugomba kuba ukwiye. Niba itinda cyane, icyuma-zinc alloy layer hamwe nigice cyiza cya zinc bizagenda bikwirakwira mugihe cyo guterura ibyuma bisya ibyuma bisobekeranye, kuburyo igice cya zinc cyera cyahinduwe rwose muburyo bwa alloy, hanyuma hakorwa firime yumukara ufite inyota, bigabanya imikorere yunamye. Mubyongeyeho, usibye kuba bifitanye isano n'umuvuduko wo guterura, bifitanye isano rya bugufi no guterura.
3. Kugenzura byimazeyo igihe cyo kwibiza zinc
Birazwi neza ko ubunini bwibyuma bifata ibyuma bifitanye isano nigihe cyo kwibiza zinc. Igihe cyo kwibiza zinc gikubiyemo cyane cyane igihe gisabwa kugirango ukureho imfashanyo yisahani hejuru yibice byashizweho hamwe nigihe gisabwa kugirango ushushe ibice byashizwemo ubushyuhe bwamazi ya zinc hanyuma ukureho ivu rya zinc hejuru yamazi nyuma yo kwibizwa kwa zinc. Mubihe bisanzwe, igihe cyo kwibiza zinc yibice byashizwemo bigenzurwa kugeza igihe igihe reaction iri hagati yibice byashizwemo namazi ya zinc irangiye hanyuma ivu rya zinc hejuru yamazi rikurwaho. Niba igihe ari gito cyane, ubwiza bwibyuma bifata ibyuma ntibishobora kwizerwa. Niba igihe ari kirekire cyane, umubyimba nubunini bwububiko biziyongera, kandi kwihanganira kwangirika kwifuniko bizagabanuka, ibyo bizagira ingaruka kumurimo wa serivisi yibyuma bisya.
