Igwe akwa akwa akwa akwa bụ ngwaahịa ejiri igwe na-ekpo ọkụ na-etinye galvanized nchara, igwe na-ekpo ọkụ na-ekpo ọkụ, igwe elektrọn galvanized, wdg, nke a na-ekpuchi ya na otu ma ọ bụ ọtụtụ n'ígwé nke mkpuchi eke n'elu mgbe emechara elu (mmebi kemịkalụ na ọgwụgwọ mgbanwe kemịkalụ) , emesịa gwọọ ya site n'enyemaka nke achịcha. Akpọrọ ya ahaeriri igwe mkpuchi agbanwere agba dị iche iche nke ihe mkpuchi organic, a na-akpọkwa ya dị ka eriri igwe agba agba agba.

Njirimara ngwaahịa

Igwe okwute agbagoro agbagoro dị arọ ma maa mma, nwere ezigbo nguzogide corrosion, enwere ike ịhazi ya ozugbo. Ha na-enye ụdị akụrụngwa ọhụrụ maka ụlọ ọrụ ihe owuwu, ụlọ ọrụ ụgbọ mmiri, ụlọ ọrụ na-emepụta ụgbọ ala, ụlọ ọrụ ngwa ụlọ, ụlọ ọrụ eletrik, wdg.

Usoro mmepụta nke eriri igwe agbagoro agba

Enwere ọtụtụ usoro mmepụta maka agba agbaeriri igwe mkpuchi agba agba. Usoro a na-ejikarị eme ihe bụ mkpuchi mkpuchi ọdịnala + usoro ịsa achịcha. Ebe ọ bụ na ọtụtụ mkpuchi maka ihe owuwu na-ekpuchi okpukpu abụọ, usoro mkpuchi abụọ na-eme achịcha na-emekarị bụ usoro mmepụta nke agba agba. Isi usoro nke ngalaba mkpuchi agba na-agụnye pretreatment, mkpuchi, na mmiri.

1) Nkwadebe nke eriri igwe

Họrọ ígwè dabara adaba dị ka mkpụrụ. Ndị a na-ejikarị eme ihe bụ ígwè galvanized, galvalume steel, zn-al-mg alloy steel, igwe oyi na-atụ oyi, wdg. Mgbe ahụ, a na-edozi ihe mkpuchi nchara n'elu, gụnyere nsị, iwepụ nchara na usoro ndị ọzọ iji hụ na adhesion nke mkpuchi.

4) ọgwụgwọ oyi akwa

Iji mee ka ihu igwe na-eguzogide ihu igwe na nkwụsị nke corrosion nke eriri agba agba, a na-ejikarị ihe mkpuchi na-ekpuchi ihe mkpuchi agba. Ihe mkpuchi nchebe nwere ike ịbụ ihe mkpuchi organic transperent ma ọ bụ ihe mkpuchi nwere ọrụ pụrụ iche, dị ka ihe mkpuchi ultraviolet, mkpuchi na-ehicha onwe ya, wdg.

2) ọgwụgwọ mbụ

A na-etinye oyi akwa nke primer n'elu igwe nchara, nke a na-ejikarị eme ka adhesion dị n'etiti mkpuchi na mkpụrụ ahụ ma nye ụfọdụ nguzogide corrosion. A na-ejikarị resin epoxy, polyester resin na ihe ndị ọzọ eme ihe mbụ.

5) ihicha na ịgwọ ọrịa

Mgbe emechara ihe mkpuchi ahụ, ọ dị mkpa ka a zipu eriri ígwè ahụ na ọkụ ihicha maka ihicha iji wepụ ihe mgbaze na mmiri dị na mkpuchi ahụ. Mgbe ahụ, a na-eziga eriri ígwè ahụ na ọkụ na-agwọ ọrịa maka ịgwọ ọrịa iji mee ka mkpuchi ahụ jikọta kpamkpam na mkpụrụ.

3) ọgwụgwọ mkpuchi agba

A na-etinye mkpuchi agba na primer. Ihe mkpuchi agba bụ isi ihe dị na eriri agba agba. Enwere ike ịhọrọ agba na mmetụta dị iche iche dịka mkpa ndị ahịa si dị. Ihe mkpuchi agba a na-ejikarị gụnyere polyester, polyester nke silicon-gbanwetụrụ, polyvinyl fluoride, wdg.

6) Ịcha na nkwakọ ngwaahịa

Enwere ike ịkpụ eriri mkpuchi agba agba agwọ ọrịa dịka mkpa ndị ahịa si nweta nha achọrọ. Mgbe ahụ ịkpụeriri igwe mkpuchi agbaa na-akwakọba iji chebe mkpuchi site na mmebi.

Ihe owuwu nke igwe agbagoro agba

1) mkpuchi elu: na-echebe ìhè anyanwụ ma gbochie ụzarị ultraviolet imebi ihe mkpuchi ahụ; mgbe topcoat rutere kpọmkwem ọkpụrụkpụ, ọ nwere ike na-etolite a ok mkpuchi mkpuchi film, mbenata mmiri permeability na oxygen permeability.
Ihe mkpuchi nke mbụ: na-enyere aka mee ka adhesion na mkpụrụ ahụ dịkwuo ike, na-eme ka ọ ghara ịdị na-eme ka agba ahụ ghara ịmịcha mgbe ihe nkiri ahụ na-agbanye na mmiri, ma na-eme ka nkwụsị nke corrosion dịkwuo mma, n'ihi na primer nwere ihe ndị na-egbochi corrosion-inhibiting pigments, dị ka chromate pigments. nke na-agafe anode ma melite nguzogide corrosion
2) oyi akwa ntụgharị kemịkalụ: na-eme ka adhesion dị n'etiti efere (galvanized, galvalume, zn-al-mg, wdg) na mkpuchi (agba)
3) Metallic mkpuchi: n'ozuzu mkpuchi zinc, mkpuchi aluzinc na zinc aluminum magnesium mkpuchi, nke nwere mmetụta kachasị na ndụ ọrụ nke ngwaahịa ahụ. Ihe mkpuchi ọla ahụ na-aba ụba, nke ukwuu na-eguzogide corrosion.
4)Base metal: A na-eji efere oyi na-atụ oyi, na ihe dị iche iche na-ekpebi arụmọrụ nke efere agba, dị ka ike
5) mkpuchi ala: na-egbochi efere ígwè ka ọ ghara imebi ya n'ime, n'ozuzu ihe nhazi nke okpukpu abụọ (2 / 1M ma ọ bụ 2/2 primer mkpuchi + mkpuchi ala), ma ọ bụrụ na ejiri ya mee ihe dị ka efere ihe mejupụtara, a na-atụ aro ka ị jiri usoro otu oyi akwa. 2/1)
