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 inoputika zinc nealuminium layers mune coating inopindirana pamusoro pesimbi kuti iite yekutanga yekudzivirira layer, iyo inotadzisa iyo inoparadza senge mvura neokisijeni kubva pakusangana ne substrate, iyo inoridza yakananga yekuzviparadzanisa mhedzisiro.
Passivation: Mukuita kwekuputira kurapwa kwechromic acid ne zinc, aluminium poda uye base metal Dacromet, iyo passivation firimu inoumbwa pamusoro pemakemikari reaction, iyo passivation firimu haiite corrosion reaction, uye inoita sechipingamupinyi.Chiito chezvinosvibisa media, pamwe chete neiyo barriers effect, 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 nhatu dzedziviriro dzinodzivirirwa dzinodzivirirwa nekuora kwepakati pesimbi pasimbi.Kune rumwe rutivi, iyo substrate yakasvibiswa nemagetsi, uye hazvishamisi kuti kune kanoverengeka kudzivirira kwechinyakare electroplating zinc.
