Yakatumirwa pa 2018-08-13Nheyo yeDacromet pamusoro pekurapa ndeyekuparadzanisa kusangana pakati pemvura, okisijeni nesimbi kuti uwane yakasimba antiseptic effect.Nheyo yacho inonyanya kubatana kwenzira nhatu dzekudzivirira.
Barrier effect: Iyo yakatsetseka zinc nealuminium layers mu coating inopindirana pamusoro pesimbi kuti iite yekutanga inodzivirira layer, iyo inotadzisa iyo inoparadza semvura neokisijeni kubva pakusangana ne substrate, iyo inoridza yakanyatso kutsaura mhedzisiro.
Passivation: Mukuita kwekuputira kurapwa kwechromic acid ne zinc, aluminium poda uye base metal Dacromet, iyo passivation firimu inoumbwa pamusoro nemakemikari reaction, iyo passivation firimu haiite corrosion reaction, uye inoita sechipingamupinyi.Chiito chezvinosvibisa media, pamwe chete nemhedzisiro, inopa maviri-layer dziviriro inosimbisa mhedzisiro yekuzviparadzanisa nevamwe.
Kudzivirirwa kweCathodic: Iyi ndiyo inonyanya kukosha yekudzivirira.Sezvakaita musimboti weiyo galvanized layer, cathodic chengetedzo inoshandiswa kune substrate pane kemikari layer nekubayira anode.
Kune rimwe divi, idzi mhando nhatu dzedziviriro dzinodzivirira kukuvadza kwepakati pesimbi pasimbi.Kune rimwe divi, iyo substrate yakasvibiswa nemagetsi, uye hazvishamisi kuti kune kakati wandei kudzivirira kwechinyakare electroplating zinc.
