Mpukutu waukulu wa silika wopangidwa ndi malata uyenera kukhala wokutidwa ndi mafuta, phata la ulusi woviikidwa mu mafuta, mafutawo azitha kuteteza phata la ulusi kuti lisawole ndi dzimbiri, waya wachitsulo umanyowetsa ulusiwo, ndi kuthira chingwe cha waya kuchokera ku chitsulo. mkati.Pamwambapo amakutidwa ndi mafuta kuti mawaya onse omwe ali mu chingwe cha chingwecho aphimbidwe mofanana ndi mafuta oletsa dzimbiri, omwe amagwiritsidwa ntchito kuti chingwe cha mgodi chinyamule mikangano ndi madzi amchere, kuti azikutidwa ndi mafuta akuda. kuchuluka kwa kuvala ndi kukana madzi mwamphamvu.Ntchito zina zimakutidwa ndi mafuta ofiira ofiira ndi filimu yolimba komanso kukana dzimbiri bwino, ndipo amafuna kuti akhale ndi mafuta ochepa, omwe ndi osavuta kuyeretsa panthawi ya opaleshoni.
Ngalava waya ❖ kuyanika ndi kanasonkhezereka, zotayidwa yokutidwa, wokutidwa ndi nayiloni kapena pulasitiki, etc. Zinki lagawidwa mu ❖ kuyanika woonda wa waya zitsulo pambuyo plating ndi ❖ kuyanika wandiweyani wa kanasonkhezereka zitsulo waya pambuyo kujambula.The makina zimatha ❖ kuyanika wandiweyani yafupika poyerekeza ndi yosalala zitsulo chingwe chingwe, amene ayenera kugwiritsidwa ntchito kwambiri dzimbiri chilengedwe.Imalimbana ndi dzimbiri, kutha komanso kutentha kuposa zingwe zamawaya, pogwiritsa ntchito plating yoyamba ndikujambula njira yopangira.Zingwe zokutidwa za nayiloni kapena waya wa pulasitiki zimagawidwa m'mitundu iwiri ya zingwe zokutidwa ndi katundu wokutira pambuyo pa chingwe.
Kupyolera mu kukonza mawaya opangira malata, sikungatalikitse moyo wake wautumiki, komanso kumapangitsanso kuti ntchito yake ikhale yogwira ntchito tsiku ndi tsiku.Chifukwa mphamvu zotchedwa electrode ya zinki ndi -0.762v, yomwe ili yoipa kuposa chitsulo, zinki imakhala anode pamene selo la galvanic limapangidwa pambuyo powonongeka ndi sing'anga.Ilo lokha limasungunuka kuteteza matrix achitsulo.Kutalika kwa chitetezo cha galvanized wire layer ndi mgwirizano waukulu ndi makulidwe.
Nthawi zambiri, mu gasi wowuma komanso kugwiritsa ntchito m'nyumba, makulidwe a zokutira zamagalasi ndi 6-12μm, koma pansi pamikhalidwe yoyipa ya chilengedwe, makulidwe a zokutira zamagalasi ndi 20μm, amatha kufikira 50μm.Choncho, zinthu zachilengedwe ayenera kuganizira posankha makulidwe kanasonkhezereka wosanjikiza.Kanasonkhezereka wosanjikiza pambuyo mankhwala passivation, akhoza mwachibadwa kupanga wosanjikiza wowala, wokongola mtundu passivation filimu, mwachionekere bwino zoteteza ntchito, kukongoletsa.
Pali mitundu yambiri ya zinc plating solution, yomwe imatha kugawidwa kukhala yankho la plating ndipo palibe yankho la plating malinga ndi momwe limakhalira.Madzi opangidwa ndi malata ali ndi kubalalitsidwa kwabwino komanso kuphimba katundu, kristalo wokutira ndi wosalala komanso wabwino, ntchitoyo ndi yosavuta, mawonekedwe ogwiritsira ntchito ndi otakata, ndipo kugwiritsidwa ntchito kwanthawi yayitali kumapangidwa.Komabe, chifukwa cha zinthu zapoizoni zomwe zili mu plating solution, mpweya wotuluka kuchokera ku plating umakhala ndi vuto lalikulu kwa thanzi la ogwira ntchito, ndipo madzi otayira ayenera kusamalidwa mosamalitsa asanatulutsidwe.
