Ni ubuhe buryo bukuru bushyushye?

Hariho ubwoko bwinshi bwibishishwa bishyushye kumasahani yicyuma. Amategeko yo gushyira mu byiciro amahame akomeye - harimo amahame y'igihugu y'Abanyamerika, Ubuyapani, Uburayi, n'Ubushinwa - arasa. Tuzasesengura dukoresheje urugero rwiburayi EN 10346: 2015 nkurugero.

Inzira nyamukuru ishyushye-igizwe nibice bitandatu byingenzi:

Zinc zishyushye zinc (Z)
Zinc-icyuma gishyushye (ZF)
Gushyushya-zinc-aluminium (ZA)
Gushyushya-aluminium-zinc (AZ)
Gushyushya-aluminium-silikoni (AS)
Zinc-magnesium ishyushye (ZM)

Ibisobanuro nibiranga ibintu bitandukanye bishyushye

Ibyuma byabanjirije gutunganywa byinjizwa mu bwogero bwashongeshejwe. Ibyuma bitandukanye bishongeshejwe mu bwogero bitanga impuzu zitandukanye (usibye ibishishwa bya zinc-fer).

Kugereranya Hagati ya Hot-Dip Galvanizing na Electrogalvanizing

1. Incamake y'ibikorwa

Galvanizing bivuga tekinike yo kuvura hejuru yo gukoresha zinc itwikiriye ibyuma, ibivanze, cyangwa ibindi bikoresho bigamije ubwiza no kurwanya ruswa. Uburyo bukoreshwa cyane ni hot-dip galvanizing hamwe nubukonje bukonje (electrogalvanizing).

2. Gahunda Zishyushye Zishyushye

Uburyo bwibanze bwo gusya ibyuma hejuru yicyuma uyumunsi ni hot-dip galvanizing. Gallvanizing ishyushye (izwi kandi nka hot-dip zinc coating cyangwa hot-dip galvanisation) nuburyo bwiza bwo kurinda ibyuma kwangirika, cyane cyane bikoreshwa mubikoresho byubatswe mubyuma bitandukanye. Harimo kwibiza ibyuma byakuweho ingese muri zinc zashongeshejwe hafi ya 500 ° C, gushira igiceri cya zinc hejuru yicyuma kugirango bigere ku kurwanya ruswa. Amashanyarazi ashyushye ashyushye: Kurangiza acide yibicuruzwa → Kwoza amazi → Gukoresha flux → Kuma → Kumanika ku mwenda → Gukonjesha treatment Kuvura imiti → Isuku → Gusiga → Gushyushya byuzuye.

3. Gukonjesha ubukonje

Ubukonje bukonje, buzwi kandi nka electrogalvanizing, bukoresha ibikoresho bya electrolytike. Nyuma yo kwangirika no gukaraba aside, ibyuma bishyirwa mubisubizo birimo umunyu wa zinc kandi bigahuzwa na terefone mbi yibikoresho bya electrolytike. Isahani ya zinc ishyizwe ahateganye na fitingi kandi ihujwe na terminal nziza. Iyo imbaraga zashyizwe mubikorwa, icyerekezo cyerekezo cyumuvuduko uva mubyiza ujya mubi bitera zinc gushira kubikoresho. Ibikoresho bikonje bikonje bikoreshwa mbere yo guterwa.

Ibipimo bya tekiniki byubahiriza ASTM B695-2000 (US) hamwe nibisobanuro bya gisirikare C-81562 yo gukanika imashini.

Kugereranya Hot-Dip Galvanizing na Cold-Dip Galvanizing

Gallvanizing ishyushye itanga imbaraga zo kurwanya ruswa cyane kuruta ubukonje bukabije (bizwi kandi nka electrogalvanizing). Amashanyarazi ya elegitoroniki asanzwe afite uburebure bwa metero 5 kugeza kuri 15 z'ubugari, mugihe impuzu zishyushye zishyushye zirenga 35 mm kandi zishobora kugera kuri 200 mkm. Gushyushya ibishyushye bitanga ubwuzuzanye hamwe nuburinganire bwuzuye butarimo ibinyabuzima. Electrogalvanizing ikoresha ibara ryuzuye zinc kugirango irinde ibyuma kwangirika. Iyi myenda ikoreshwa hejuru yuburinzi hakoreshejwe uburyo ubwo aribwo bwose, ikora igipande cyuzuye zinc nyuma yo gukama. Igishishwa cyumye kirimo ibintu byinshi bya zinc (kugeza 95%). Icyuma gishyirwa hejuru ya zinc hejuru yacyo mugihe gikonje, mugihe ubushyuhe-bushyushye burimo gusiga imiyoboro y'ibyuma hamwe na zinc binyuze mu kwibiza. Ubu buryo butanga imbaraga zidasanzwe, bigatuma igifuniko kirwanya cyane.

Nigute ushobora gutandukanya ubushyuhe-dip na galvanizing ikonje?

1. Kumenyekanisha

Ubushuhe bushyushye busa nkaho bugaragara muri rusange, bwerekana ibimenyetso biterwa n'amazi, ibitonyanga, na nodules - cyane cyane bigaragara kumpera yumurimo. Muri rusange isura ni silver-yera.

Ubuso bwa Electrogalvanised (ubukonje-galvanised) busa neza, cyane cyane umuhondo-icyatsi kibisi, nubwo iridescent, ubururu-bwera, cyangwa umweru ufite icyatsi kibisi nacyo gishobora kugaragara. Ubusanzwe iyi sura ntigaragaza zinc nodules cyangwa clumping.

2. Gutandukanya inzira

Gushyushya ibishyushye birimo intambwe nyinshi: kugabanuka, gufata aside, kwibiza imiti, kumisha, hanyuma kwibiza muri zinc yashongeshejwe mugihe runaka mbere yo kuyikuraho. Iyi nzira ikoreshwa mubintu nka hot-dip galvanised imiyoboro.

Ubukonje bukonje, ariko, mubyukuri ni amashanyarazi. Ikoresha ibikoresho bya electrolytike aho igihangano cyangirika no gutoroka mbere yo kwibizwa mumuti wumunyu wa zinc. Ihujwe nibikoresho bya electrolytike, urupapuro rwakazi rushyira urwego rwa zinc binyuze mu cyerekezo cyerekezo cyumuyaga hagati ya electrode nziza kandi mbi.
