galvanized na-ekpo ọkụ
N'oge usoro galvanizing, a na-emikpu ígwè ahụ n'ime bat zinc a wụrụ awụ. Hot-mikpu galvanizing (HDG) na-agụnye nzọụkwụ atọ bụ isi: nkwadebe elu, ịgbanye ọkụ, na nyocha.
Nkwadebe elu
N'ime usoro nkwadebe nke elu, a na-eziga nchara a na-emepụta ihe maka galvanizing ma na-enweta ọkwa nhicha atọ: nkwụsịtụ, ịsacha acid na fluxing. Na-enweghị usoro nhicha a, galvanizing enweghị ike ịga n'ihu n'ihi na zinc agaghị emeghachi omume na nchara adịghị ọcha.
Galvanizing
Mgbe emechara nkwadebe elu, a na-emikpu nchara ahụ na zinc a wụrụ awụ 98% na 830ºF. Akụkụ nke a na-agbanye ígwè n'ime ite kwesịrị ikwe ka ikuku gbapụ na ụdị tubular ma ọ bụ akpa ndị ọzọ. Nke a na-enye ohere ka zinc gafere na n'ime ahụ nchara dum. N'ụzọ dị otú a, zinc na-abanye na kọntaktị na ígwè dum. Ígwè dị n'ime ígwè ahụ na-amalite imeghachi omume na zinc, na-akpụ mkpuchi zinc-iron intermetallic. N'akụkụ mpụta, a na-etinye ihe mkpuchi zinc dị ọcha.
Nyocha
Nzọụkwụ ikpeazụ bụ inyocha mkpuchi. A na-eme nlele anya iji chọpụta ebe ọ bụla a na-ekpuchighị ya na ahụ ígwè, n'ihi na mkpuchi ahụ agaghị adabere na nchara na-adịghị ọcha. A nwekwara ike iji ihe nrịbama magnetik chọpụta ọkpụrụkpụ mkpuchi.
2 Electro galvanizing
A na-emepụta ígwè elektrogalvanized site na usoro electrochemical. N'ime usoro a, a na-agbanye ígwè ahụ n'ime bat zinc, a na-agafekwa ọkụ eletrik na ya. A na-akpọkwa usoro a dị ka electroplating.
Tupu usoro electrogalvanizing, a ga-ehichapụ ígwè ahụ. N'ebe a, zinc na-arụ ọrụ dị ka anode iji chebe ígwè. Maka electrolysis, zinc sulfate ma ọ bụ zinc cyanide na-eji dị ka electrolyte, ebe cathode na-echebe ígwè site na corrosion. Nke a na-eme ka zinc nọgide na-adị n'elu ígwè dị ka ihe mkpuchi. Ogologo oge a na-agbanye ígwè ahụ n'ime bat zinc, otú ahụ ka mkpuchi na-adịwanye ukwuu.
Iji kwalite nguzogide corrosion, ụfọdụ mkpuchi ngbanwe na-arụ ọrụ nke ukwuu. Usoro a na-emepụta ihe mkpuchi ọzọ nke zinc na chromium hydroxides, na-ebute ọdịdị na-acha anụnụ anụnụ na elu igwe.
3 Zinc ntinye
Zinc plating na-agụnye ịkpụ mkpuchi zinc n'elu ígwè ma ọ bụ ígwè iji gbochie nbibi ígwè.
N'ime usoro a, a na-etinye ígwè n'ime akpa nwere zinc, nke a na-ekpuchi ya ma kpoo ọkụ na okpomọkụ n'okpuru ebe mgbaze nke zinc. Nsonaazụ nke mmeghachi omume a bụ nguzobe nke zinc-iron alloy, nke nwere akwa akwa dị n'èzí nke zinc dị ọcha na-arapara n'elu ígwè ma na-enye nnukwu nkwụsị nke corrosion. Ihe mkpuchi a na-emekwa ka mma nkedo agba dị n'elu.
Maka obere ihe ọla, zinc plating bụ ụzọ kacha mma. Usoro a na-adabara maka ihe ndị na-emepụta nchara na-adịghị agbanwe agbanwe, n'ihi na oyi akwa dị n'elu nwere ike ịgbaso ụkpụrụ nke nchara isi.
4 Igwe na-efesa
N'ime usoro ịgbasa zinc plain metal, a na-efesa ụmụ irighiri ihe zinc gbazere ma ọ bụ atomized n'elu igwe. A na-eme usoro a site na iji egbe ịgbasa aka ma ọ bụ ọkụ pụrụ iche.
Tupu itinye mkpuchi zinc, a ga-ewepụrịrị ihe niile na-emerụ emerụ, dị ka mkpuchi elu na-achọghị, mmanụ na nchara. Mgbe usoro nchacha ahụ mechara, a na-efesa ụmụ irighiri ihe zinc a wụrụ awụ n'elu ala siri ike, ebe ha na-esiwanye ike.
Usoro mkpuchi mkpuchi ígwè a bụ nke kachasị mma maka igbochi peeling na flaking, ma ọ dịghị mma maka inye nnukwu nguzogide corrosion.
Ogologo oge ole ka mkpuchi zinc na-adịru?
Banyere ịdịte aka, ọ na-adaberekarị n'ịdị arọ nke mkpuchi zinc, yana ihe ndị ọzọ dị ka ụdị gburugburu ebe obibi, ụdị mkpuchi zinc ejiri, na àgwà nke agba ma ọ bụ ihe mkpuchi. Ihe mkpuchi zinc na-aba ụba, ogologo ndụ ahụ.
Hot-mikpu galvanizing vs. oyi galvanizingIhe mkpuchi galvanized na-ekpo ọkụ na-adịte aka karịa mkpuchi galvanized oyi n'ihi na ha na-adịkarị oke ma sie ike karị. Ịtụnye ọkụ na-ekpo ọkụ na-agụnye iminye ígwè ahụ n'ime zinc a wụrụ awụ, ebe n'usoro ikuku oyi, a na-efesa otu ma ọ bụ abụọ n'ígwé ma ọ bụ na-ehicha ya.
N'ihe banyere ịdịte aka, mkpuchi galvanized na-ekpo ọkụ nwere ike ịdịru ihe karịrị afọ 50 n'agbanyeghị ọnọdụ gburugburu ebe obibi. N'ụzọ dị iche, mkpuchi galvanized oyi na-adịru nanị ọnwa ole na ole ruo afọ ole na ole, dabere na ọkpụrụkpụ mkpuchi ahụ.
Na mgbakwunye, na gburugburu ebe na-emebi emebi dị ka ntọala ụlọ ọrụ mmepụta ihe, ogologo ndụ nke mkpuchi zinc nwere ike ịdị oke. Ya mere, ịhọrọ mkpuchi zinc dị elu na idobe ha ogologo oge dị oke mkpa maka ịkwalite nchebe megide corrosion, iyi, na nchara.
