Ọkpụrụkpụ mkpuchi bụ ọnọdụ nkwa kachasị mkpa maka nguzogide corrosion.Ka ọkpụrụkpụ mkpuchi ahụ buru ibu, ka nguzogide corrosion na-akawanye mma, nke egosipụtara site n'ọtụtụ ule agbagoro agbagoro na nyocha imi imi.
Dị ka egosiri n'okpuru:

N'ihi na agba ígwè efere dabere na (aluminom) zinc plated efere, mkpuchi ọkpụrụkpụ tumadi na-emetụta notch corrosion arụmọrụ nke agba ígwè efere.The thinner na mkpụrụ, na thicker na zinc oyi akwa, na mma nke corrosion iguzogide nke ịkpụ.A na-amata ugbu a n'ụwa niile na zinc ratio ≥ 100 bụ nchebe dị irè megide corrosion nke agba agba agba.

Otu esi ahọrọ ụdị mkpuchi
Ọrụ bụ isi nke mkpuchi ahụ na-egosipụta na ma mmetụta anya na ọrụ nchebe.Enwere ike kewaa pigmenti nke mkpuchi ahụ n'ime pigmenti organic na inorganic pigments, na-egbuke egbuke na agba;Nri inorganic n'ozuzu na-acha ọkụ, mana ihe ha na-emepụta kemịkal na nguzogide UV dị elu karịa pigmenti organic.
Uwe elu ndị a na-ejikarị eme ihe maka efere nchara nwere agba gụnyere polyester (PE), polyester modified silicon (SMP), polyester dị elu (HDP), na polyvinylidene fluoride (PVDF).Uwe elu ọ bụla dabara adaba maka ọnọdụ dị iche iche, anyị na-akwado iji ngwaahịa HDP ma ọ bụ PVDF mgbe akụ na ụba kwere.

Maka nhọrọ nke primer, ekwesịrị ịhọrọ resin epoxy ma ọ bụrụ na a na-emesi ike na nguzogide na corrosion;Maka nlebara anya karịa na mgbanwe na nguzogide UV, họrọ polyurethane primer.
Maka mkpuchi azụ, ọ bụrụ na a na-eji efere ígwè na-acha agba agba dị ka otu efere, họrọ nhazi nke okpukpu abụọ, ya bụ, otu oyi akwa nke azụ azụ na otu oyi akwa nke azụ.Ọ bụrụ na a na-eji efere ígwè nwere agba agba dị ka ihe mejupụtara ma ọ bụ efere Sanwichi, a na-etinye akwa epoxy resin n'azụ.

Mmetụta nke mkpuchi mkpuchi na ndụ ọrụ
Mkpuchi efere ígwè na-acha agba nwere ike ịrụ ọrụ ụfọdụ na mgbochi corrosion, na-eji ihe nkiri mkpuchi na-ekewapụ ihe ndị na-emerụ emerụ na mpụga.Otú ọ dị, n'ihi ọdịdị microscopic nke ihe nkiri mkpuchi ahụ n'onwe ya, a ka nwere pores, na obere ikuku mmiri na ikuku ka ga-abanye na mkpuchi ahụ, na-eme ka ọnya nke mkpuchi ahụ na ikekwe na-eme ka ihe nkiri mkpuchi ahụ daa.Maka efere ígwè, ịkwanye
Ihe oyi akwa (zinc plated ma ọ bụ aluminum zinc plated) nwere mmetụta dị ukwuu na ndụ nke efere ígwè.
Maka otu mkpuchi mkpuchi ahụ, mkpuchi nke abụọ dị oke karịa mkpuchi nke mbụ, yana nguzogide corrosion ka mma na ogologo ndụ ọrụ.Maka ọkpụrụkpụ mkpuchi, dabere na nsonaazụ nnwale corrosion dị mkpa, anyị na-akwado na mkpuchi ihu bụ 20 um ma ọ bụ karịa, ebe ọkpụrụkpụ ihe nkiri zuru oke nwere ike igbochi corrosion n'ime oge nkwado.
