Kedu ka esi egbochi aluminom corrosion?

Aluminom na-adịghị agwọ ọrịa nwere ezigbo nguzogide corrosion n'ọtụtụ gburugburu, mana na gburugburu acid siri ike ma ọ bụ alkaline, aluminum na-emebikarị ngwa ngwa.Nke a bụ ndepụta nlele otu ị nwere ike isi gbochie nsogbu corrosion aluminum.

Mgbe ejiri ya mee ihe n'ụzọ ziri ezi, aluminum nwere ogologo ndụ karịa ọtụtụ ihe ndị ọzọ na-ewu ụlọ, gụnyere carbon steel, galvanized steel na ọla kọpa.Ogologo ya dị oke mma.Ọ dịkwa elu karịa ihe ndị ọzọ dị na gburugburu sọlfọ na oke mmiri.

Ụdị corrosion kachasị ewu ewu bụ:

• Galvanic corrosion nwere ike ime ebe enwere ma kọntaktị ọla yana akwa electrolytic n'etiti ọla dị iche iche.
• Nrụrụ nke pitting na-apụta naanị na ọnụnọ electrolyte (ma mmiri ma ọ bụ mmiri) nwere nnu gbazere, na-abụkarị chlorides.
• Nrụrụ Crevice nwere ike ime na oghere dị warara, nke jupụtara na mmiri.

Ya mere, gịnị ka ị pụrụ ime iji zere ya?

Nke a bụ ndepụta nlele m maka otu esi egbochi corrosion:

• Tụlee imewe profaịlụ.Nhazi nke profaịlụ kwesịrị ịkwalite ihicha - ezigbo drainage, iji zere mmebi.Ị kwesịrị ịzenarị inwe aluminom na-enweghị nchebe na ogologo kọntaktị na mmiri na-adịghị, ma zere akpa ebe unyi nwere ike ịnakọta wee debe ihe ahụ mmiri ruo ogologo oge.
• Tụlee ụkpụrụ pH.Ekwesịrị izere ụkpụrụ pH dị ala karịa 4 ma dị elu karịa 9 iji chebe site na mmebi.
• Lezienụ anya na gburugburu ebe obibi:N'ebe ndị siri ike, karịsịa ndị nwere nnukwu chloride, a ghaghị ilebara anya na ihe ize ndụ nke corrosion galvanic.N'ebe ndị dị otú ahụ, a na-atụ aro ụfọdụ ụdị mkpuchi n'etiti aluminom na ọla ndị ọzọ mara mma, dị ka ọla kọpa ma ọ bụ igwe anaghị agba nchara.
• Corrosion na-abawanye na stagnation:Na mechiri emechi, usoro nwere mmiri mmiri, ebe mmiri na-anọgide na-adị ogologo oge, corrosion na-abawanye.Enwere ike iji ihe mgbochi na-enye nchebe corrosion mgbe mgbe.
• Zeresmgbede, gburugburu mmiri.Dị ka o kwesịrị, mee ka aluminom kpọọ nkụ.Ekwesịrị ịtụle nchedo Cathodic na gburugburu ebe siri ike, mmiri mmiri iji gbochie mmebi.
