Byoherejwe 2018-08-13Ihame ryo kuvura hejuru ya Dacromet ni ugutandukanya imikoranire hagati yamazi, ogisijeni nicyuma kugirango ubone ingaruka zikomeye za antiseptique.Ihame nubufatanye cyane muburyo butatu bwo kurinda.
Ingaruka ya bariyeri: Ibice bya zinc na aluminiyumu bifatanye hejuru yicyuma kugirango bibe urwego rwa mbere rwo gukingira, rubuza uburyo bwangirika nkamazi na ogisijeni guhura na substrate, bigira ingaruka zikomeye zo kwigunga.
Passivation: Muburyo bwo kuvura acide chromic hamwe na zinc, ifu ya aluminium hamwe nicyuma fatizo Dacromet, firime ya passivation yakozwe hejuru yubushakashatsi bwa chimique, firime ya passivation ntabwo ikunda kwangirika, kandi ikora nka bariyeri.Igikorwa cyitangazamakuru ryangirika, hamwe ningaruka za bariyeri, ritanga uburinzi bubiri bushimangira ingaruka zo kwigunga kumubiri.
Kurinda Cathodic: Izi ningaruka zingenzi zo kurinda.Kimwe nihame ryurwego rwa galvanis, kurinda catodiki bikoreshwa kuri substrate kurwego rwa chimique mugutamba anode.
Ku ruhande rumwe, ubu bwoko butatu bwo kurinda bugaragaza ingaruka mbi zo kwangirika kwicyuma.Ku ruhande rumwe, substrate yangiritse amashanyarazi, kandi ntibitangaje ko hari inshuro nyinshi ingaruka zo kurinda zinc gakondo ya electroplating.
