Ihe na-akpata corrosion na ụzọ mgbochi corrosion maka aluminom Alloy na ụgbọ oloko dị elu

A na-emepụta ahụ na nko-beam nke ụgbọ oloko dị elu site na iji aluminum alloy, mara maka uru ya dị ka njupụta dị ala, oke ike na-adị arọ, ezigbo nguzogide corrosion, na arụmọrụ dị ala dị ala.Site na iji aluminom dochie ihe nchara ọdịnala, ịdị arọ nke ahụ ụgbọ oloko na-ebelata nke ukwuu, na-eduga n'ibelata ike ike, belata mmetọ gburugburu ebe obibi, na imepụta ma uru akụ na ụba na nke ọha.

Otú ọ dị, aluminom na aluminom alloys nwere mmetụta kemịkal na-arụ ọrụ nke ukwuu.N'agbanyeghị ịmepụta ihe nkiri oxide dị oke egwu mgbe ekpughere ikuku oxygen na gburugburu ebe obibi, na-enye nguzogide corrosion ka mma karịa ígwè nkịtị, corrosion nwere ike ime mgbe a na-eji alloy aluminum mee ihe na ụgbọ oloko dị elu.Ebe mmiri na-emebi emebi, gụnyere ịgbasa, ikuku ikuku, na mmiri na-ekupụ n'ala mgbe a na-adọba ụgbọala, nwere ike imebi ihe nkiri oxide.Corrosion na aluminum alloy eji na aru nke ụgbọ oloko dị elu na-egosipụtakarị dị ka corrosion otu, pitting corrosion, crevice corrosion, na corrosion nrụgide, na-eme ka ọ bụrụ usoro mgbagwoju anya nke ma ihe gburugburu ebe obibi na ihe ndị na-emepụta ihe na-emetụta ya.

Enwere ụzọ dị iche iche maka mgbochi corrosion nke aluminom alloy, dị ka itinye mkpuchi anticorrosive iji kewapụ mkpụrụ osisi alloy nke ọma na gburugburu mpụga.Ihe mkpuchi mgbochi na-ahụkarị bụ epoxy resin primer, nke a na-ejikarị eme ihe maka ezigbo nguzogide mmiri ya, nrapado siri ike, yana ndakọrịta na mkpuchi dị iche iche.

Otú ọ dị, e jiri ya tụnyere ụzọ mgbochi nchara anụ ahụ, ụzọ dị irè karị bụ ọgwụgwọ nkwụsị nke kemịkal.Mgbe passivation ọgwụgwọ nke aluminom na aluminum alloys, ngwaahịa ọkpụrụkpụ na n'ibu kpọmkwem na-anọgide na-adịghị emetụta, na ọ dịghị mgbanwe na ọdịdị ma ọ bụ agba.Usoro a na-adaba adaba ma na-enye ihe nkiri passivation kwụsiri ike na nke corrosion na-eguzogide ma e jiri ya tụnyere mkpuchi mgbochi ọdịnala.Ihe nkiri passivation nke emere site na aluminom alloy passivation treatment na-akwụsi ike ma nwee nguzogide corrosion dị elu karịa mkpuchi anticorrosive ọdịnala, yana uru agbakwunyere nke ịrụ ọrụ nrụzi onwe onye.

Anyị chromium-free passivation ngwọta, KM0425, kwesịrị ekwesị maka passivating aluminum ihe, aluminum alloys, na anwụ-nkedo aluminum ngwaahịa, na-eme ka ha corrosion iguzogide.Ọ bụ ngwaahịa ọhụrụ na nke dị elu maka njedebe izugbe nke ihe aluminom.Emebere ya na acid organic, ihe ndị na-adịghị ahụkebe nke ụwa, ndị na-egbochi corrosion dị elu, yana obere ihe na-eme ngwa ngwa passivation arọ dị elu, ọ nweghị acid, ọ naghị egbu egbu, na enweghị isi.N'ikwekọ n'ụkpụrụ RoHS gburugburu ebe obibi ugbu a, iji ngwọta ngafe a na-eme ka a mara na usoro ngafe adịghị emebi agba mbụ na akụkụ nke workpiece ma na-emeziwanye nguzogide nke ihe aluminom na ịgba nnu.
