Kedu ka efere ígwè nwere agba agba na-esi enweta mgbochi corrosion? Efere nchara nwere agba agba, nke a makwaara dị ka efere nchara agba agba, bụ nsonaazụ nke ngwakọta nke mkpuchi, oyi akwa tupu ọgwụgwọ, primer na topcoat. Anyị na-akpọ ya "anọ n'ime otu mgbochi corrosion usoro nke agba mkpuchi ígwè efere". A na-eji bọọdụ mkpuchi agba anyị nwere ụdị mkpuchi dị iche iche ma kpuchie ya site na edemede 5 na usoro 48, yana ezigbo mgbochi nchara.
Nguzogide corrosion na nguzogide na-ada ada na-adịte aka.

Olee otú anyị ga-esi nweta mgbochi corrosion nke agba ntekwasa efere ígwè? Efere nchara nwere agba agba, nke a makwaara dị ka efere nchara agba agba, bụ nsonaazụ nke ngwakọta nke mkpuchi, oyi akwa tupu ọgwụgwọ, primer na topcoat. Anyị na-akpọ ya "anọ n'ime otu mgbochi corrosion usoro nke agba mkpuchi ígwè efere".
Ihe mkpuchi nke efere ígwè agba agba na-arụ ọrụ mgbochi corrosion nke ịchụ àjà. N'ikwu ya n'ụzọ dị mfe, ọ na-agbatị ndụ ọrụ nke efere ígwè site n'ịnọgide na-eri ihe mkpuchi nke ya. N'ezie, ụdị, àgwà, na ọkpụrụkpụ nke mkpuchi bụ isi ihe na ogologo oge mkpuchi mkpuchi. Agba anyị agba agba agba agba agba na-ejikarị galvanized, zinc aluminum, galvanized aluminum magnesium na efere ígwè ndị ọzọ na-esi na nnukwu ụlọ nchara ụlọ, nke nwere ike dị elu na nguzogide corrosion ka mma.
Ka anyị kwuo maka oyi akwa ọgwụgwọ tupu ọgwụgwọ ọzọ. Nke a bụ akụkụ dị oke mkpa nke mgbochi corrosion nke efere ígwè agba, nke a na-elegharakarị anya. Okpokoro ọgwụgwọ tupu ọgwụgwọ, nke a makwaara dị ka oyi akwa passivation, chọrọ iji ngwọta passivation dị ka phosphate ma ọ bụ chromate na-agafe n'elu ala tupu mkpuchi agba. Nke a ọ bụghị nanị na-eme ka adhesion nke mkpuchi ahụ dịkwuo elu, kamakwa ọ na-ekere òkè na nkwụsị nke corrosion. Nnyocha egosila na n'ime nnwale nguzogide nnu nnu na-anọpụ iche nke efere galvanized agba agba, ọnụego onyinye nke ogo oyi akwa tupu ọgwụgwọ erute ihe karịrị 60%.
Ka anyị kwuo maka primer ọzọ. N'otu aka ahụ, primer na-ekere òkè n'ịba ụba nke mkpuchi mkpuchi. Mgbe ihe nkiri agba ahụ ga-agafe, ọ gaghị ewepụ ya na mkpuchi ahụ, na-egbochi ọnya na nkwụsị nke mkpuchi ahụ. N'aka nke ọzọ, n'ihi ọnụnọ nke pigmenti na-ewepụta ngwa ngwa dị ka chromates na primer, ọ nwere ike ịfefe anode ma melite nguzogide corrosion nke mkpuchi.

N'ikpeazụ, ka anyị kwuo banyere topcoat. Na mgbakwunye na ihe ịchọ mma, topcoat na-abụkarị iji gbochie ìhè anyanwụ ma gbochie mmebi UV na mkpuchi ahụ. Mgbe topcoat ruru otu ọkpụrụkpụ, ọ nwere ike ibelata ọgbọ nke micropores, si otú ahụ na-echebe ntinye nke mgbasa ozi na-emebi emebi, na-ebelata mmiri na ikuku oxygen nke mkpuchi, na igbochi mkpuchi mkpuchi. Nguzogide UV na njupụta nke mkpuchi dị iche iche dịgasị iche iche, na maka otu ụdị mkpuchi ahụ, ọkpụkpụ nke ihe nkiri agba bụ isi ihe na-emetụta corrosion. A na-eme mbadamba ihe mkpuchi agba anyị site n'ịhọrọ ụdị mkpuchi dị iche iche nke a gwọọla na okpomọkụ dị elu, na-eme ka nguzogide corrosion dị elu na ịrụ ọrụ mgbochi na-adịte aka.
