Kubyuma bifata ibyuma, kuvura hejuru ni inzira hamwe byanze bikunze, abacuruzi benshi mukubaza ibyerekeranye na feri, uburyo bwo kuvura hejuru, umuyoboro usanzwe ukurikije amakuru ahinnye yerekeranye nubuso bwibikoresho bya screw inzira zisanzwe zitunganyirizwa hari ubwoko umunani yuburyo, nka: umukara (ubururu), fosifatiya, dip zinc zishyushye, dacromet, amashanyarazi, amashanyarazi ya chrome, nikel na zinc.Ubuvuzi bwihuta bwibikoresho byifashishwa muburyo runaka bwo gukora igipfukisho hejuru yumurimo wakazi, intego yacyo ni ugukora ubuso bwibicuruzwa byiza, kurwanya ruswa.
Uburyo umunani bwo kuvura hejuru yuburyo bwihuta:
1, Umukara (ubururu)
Ibifunga bigomba kuvurwa n'umukara byashyizwe mu kigega cyo gukemura (145 ± 5 ℃) cya hydroxide ya sodium (NaOH) na sodium nitrite (NaNO2) ya okiside ishushe hamwe na okiside, hejuru y’ibyuma bifata ibyuma bitanga urwego rwa magnetiki Fe3O4 (Fe3O4) ) firime, ubunini muri rusange 0,6 - 0.8μm umukara cyangwa ubururu bwirabura.Byombi HG / 20613-2009 na HG / T20634-2009 kubipimo bifata ibyuma bikoresha ingufu bisaba gutunganya ubururu.
2, Fosifati
Fosifatiya ni inzira yo gukora fosifate yimiti ihinduranya imiti na chimique na electrochemic reaction.Filime yo guhindura fosifate yitwa firime ya fosifati.Intego ya fosifate nugutanga uburinzi bwicyuma fatizo no gukumira icyuma kwangirika kurwego runaka.Ikoreshwa nka primer mbere yo gushushanya kugirango irusheho gukomera no kwangirika kwa firime irangi;Irashobora gukoreshwa mukugabanya ubukana no gusiga amavuta mugihe gikonje gikora.Igipimo cya diameter nini ya kabiri - imitwe yimitwe yumuvuduko ukenera fosifati.
3, Gushyushya gushya
Gushyira zinc ishyushye nugushira umunyamuryango wibyuma nyuma yo gukuramo ingese mumuti wa zinc ushonga mubushyuhe bwinshi kuri 600 ℃, kuburyo ubuso bwumunyamuryango wibyuma bufatanije nigice cya zinc.Ubunini bwurwego rwa zinc ntibushobora kuba munsi ya 65 mm kuri plaque yoroheje iri munsi ya 5mm, kandi ntibiri munsi ya 86 mm kuri plaque yuzuye 5mm no hejuru.Kina rero intego yo gukumira ruswa.
4. Dacroll
DACROMET nubusobanuro bwa DACROMET hamwe nincamake, DACROMET, ingese ya DACROMET, Dicron.Nibintu bishya birwanya anticorrosive hamwe nifu ya zinc, ifu ya aluminium, aside chromic namazi ya deionised nkibice byingenzi.Nta kibazo cya hydrogène cyo gukuramo, kandi torque-preload ihoraho nibyiza cyane.Niba kurengera ibidukikije bya chromium ya hexavalent bidasuzumwe, mubyukuri birakwiriye cyane kubifata imbaraga nyinshi hamwe na anticorrosion nyinshi.
5, amashanyarazi
Electrogalvanizing, izwi kandi nk'ubukonje bukabije mu nganda, ni inzira yo gukoresha electrolysis kugirango ikore icyuma kimwe, cyinshi kandi gihujwe neza nicyuma cyangwa ibishishwa byoherejwe hejuru yumurimo.Ugereranije n’ibindi byuma, zinc irahendutse kandi yoroshye gutwikira icyuma, agaciro gake gashobora kwangirika kwangirika kwamashanyarazi, ikoreshwa cyane mukurinda ibice byibyuma, cyane cyane kwangirika kwikirere, kandi bikoreshwa mugushushanya.Tekinike yo gushiraho irimo isahani (cyangwa kumanika isahani), isahani (ibereye kubice bito), isahani yubururu, isahani yikora kandi ikomeza isahani (ibereye insinga, umurongo).
Electrogalvanizing nigikoresho gikoreshwa cyane kubifunga ubucuruzi.Nibihendutse kandi bisa neza, kandi birashobora kuza mwirabura cyangwa ingabo icyatsi.Nyamara, imikorere ya anticorrosion ni rusange, imikorere ya anticorrosion niyo yo hasi cyane muri plaque ya zinc (coating).Ikizamini rusange cya electrogalvanizing ikizamini cyumunyu utagira aho kibogamiye mugihe cyamasaha 72, hariho no gukoresha kashe idasanzwe, bigatuma ikizamini cyumunyu utagira aho kibogamiye cyamasaha arenga 200, ariko igiciro gihenze, nikubye inshuro 5 ~ 8 rusange muri rusange.
Ibifunga ibice byubatswe mubisanzwe bifite ibara rya zinc na zinc yera, nka 8.8 urwego rwubucuruzi.
6, Chrome yashizwemo
Isahani ya Chrome nugutezimbere cyane gukomera hejuru, ubwiza, kwirinda ingese.Isahani ya Chromium ifite imiti ihamye kandi ntishobora kwitwara muri alkali, sulfide, aside nitricike na aside nyinshi kama, ariko irashobora gushonga muri aside hydrohalic (nka aside hydrochloric) na aside ya sulfurike ishyushye.Chromium iruta ifeza na nikel kuko idahindura ibara kandi ikagumana ububengerane bwayo igihe kirekire iyo ikoreshejwe.
7, isahani ya Nickel
Isahani ya Nickel ahanini irwanya kwambara, kurwanya ruswa, kurwanya ingese, muri rusange umubyimba muto wibikorwa bigabanijwemo amashanyarazi na chimique ibyiciro bibiri.
8, Gutera inda
Ihame rya tekinoroji ya powder zincizing nugushira ibikoresho bya zincizing hamwe nicyuma nicyuma mubice bya zincizing hamwe nubushyuhe bugera kuri 400 and, kandi atom zinc zikora zizinjira mubice byicyuma nicyuma kuva hanze kugeza imbere.Muri icyo gihe, atome z'icyuma zikwirakwira imbere, zigizwe na zinc-fer intermetallic compound, cyangwa cinc coating, hejuru yibice by'ibyuma.
