Plating
Makulidwe a zokutira ndiye chitsimikizo chofunikira kwambiri pakukana dzimbiri.Kukula kwa makulidwe a zokutira, kumapangitsanso kukana kwa dzimbiri, komwe kwatsimikiziridwa ndi mayeso ambiri othamanga komanso mayeso okhudzana ndi mphuno.
Monga momwe zilili pansipa:

Kwa mbale zitsulo zamtundu zochokera (zo aluminiyamu) zokhala ndi zinki, makulidwe okutira kumakhudza kwambiri magwiridwe antchito a notch amitundu yachitsulo.Kuchepa kwa gawo lapansi, kukulitsa kwa zinki, komanso kukana dzimbiri kwa odulidwawo.Pakali pano zimadziwika padziko lonse lapansi kuti chiŵerengero cha zinc ≥ 100 ndi chitetezo chogwira ntchito ku notch dzimbiri za mbale zokutira zitsulo.
Satifiketi.Kutengera gawo laling'ono la 0.5mm monga chitsanzo, zomwe zili pa sikweya mita imodzi mbali imodzi ziyenera kufika osachepera 50g.

Momwe mungasankhire mtundu wa zokutira
Udindo waukulu wa zokutira umawonetsedwa pazowoneka ndi ntchito zoteteza.The inki wa ❖ kuyanika akhoza kugawidwa mu inki organic ndi inorganic inki, ndi mitundu yowala ndi kuwala;Inorganic pigment nthawi zambiri imakhala yamitundu yopepuka, koma mawonekedwe ake amankhwala komanso kukana kwa UV ndipamwamba kuposa inki yachilengedwe.
Zovala zapamwamba zomwe zimagwiritsidwa ntchito kwambiri pama mbale azitsulo amitundu ndi monga poliyesitala (PE), silicon modified polyester (SMP), polyester yapamwamba kwambiri (HDP), ndi polyvinylidene fluoride (PVDF).Chovala chilichonse chimakhala choyenera pamikhalidwe yosiyanasiyana, ndipo timalimbikitsa kugwiritsa ntchito zinthu za HDP kapena PVDF ngati chuma chilola.

Posankha primer, epoxy resin iyenera kusankhidwa ngati kumamatira ndi kukana kwa dzimbiri kumatsindika;Kuti mumve zambiri pakusinthasintha komanso kukana kwa UV, sankhani choyambira cha polyurethane.
Kwa chophimba chakumbuyo, ngati mbale yachitsulo yopangidwa ndi mtundu ikugwiritsidwa ntchito ngati mbale imodzi, sankhani mawonekedwe a magawo awiri, ndiko kuti, gawo limodzi lachiyambi cham'mbuyo ndi mzere umodzi womaliza.Ngati mbale yokutidwa ndi chitsulo imagwiritsidwa ntchito ngati mbale yophatikizika kapena sangweji, utomoni wa epoxy umagwiritsidwa ntchito kumbuyo.

Zotsatira za makulidwe a zokutira pa moyo wautumiki
Chophimba chachitsulo chamitundu chamitundu chingathe kuchitapo kanthu popewa dzimbiri, pogwiritsa ntchito filimu yopaka utoto kuti mulekanitse zinthu zowononga zakunja.Komabe, chifukwa cha mawonekedwe ang'onoang'ono a filimu yophimba yokha, pamakhala pores, ndipo mpweya wochepa wa madzi mumlengalenga udzalowabe, kuchititsa matuza a zokutira ndipo mwina kuchititsa kuti filimu yophimbayo igwe.Kwa mbale yachitsulo, plating
Chosanjikiza (zinc chokutidwa kapena aluminiyamu yazinki) chimakhudza kwambiri moyo wa mbale yachitsulo.
Kwa makulidwe omwewo ❖ kuyanika, ❖ kuyanika kwachiwiri kumakhala kocheperapo kuposa kuyara koyambirira, kukana kwa dzimbiri bwino komanso moyo wautali wautumiki.Pa makulidwe a zokutira, kutengera zotsatira zoyeserera za dzimbiri, timalimbikitsa kuti zokutira zakutsogolo zikhale 20 um kapena kupitilira apo, chifukwa makulidwe amafilimu okwanira amatha kupewa dzimbiri mkati mwa nthawi yovomerezeka.
Pewani kuwonongeka kwa dzimbiri (PVDF imafuna makulidwe opaka utoto wokulirapo chifukwa cha moyo wautali wautumiki, nthawi zambiri 25 μ M kapena kupitilira apo).
