Byoherejwe 2018-10-29Hamwe niterambere ryihuse ryikoranabuhanga rigezweho, ibicuruzwa byinshi kandi byubuhanga buhanitse bikoreshwa mubikorwa, cyane cyane mubikorwa byo gutunganya.Tekinoroji yo gutunganya yazanye ibintu byinshi mubuzima bwacu, harimo na Dacromet.
Ipitingi ya Dacromet, izwi kandi nka zinc flake coating, ikoreshwa cyane mubikorwa byinshi.Muri byo, guhuza tekinoroji ya Dacromet hamwe na coatings byongera cyane imikorere yo kurwanya ruswa yibicuruzwa.Noneho uzi impamvu ishobora kurinda ibikoresho?
Ipitingi ya Dacromet ni materi ya silver-imvi kandi igizwe nibice byiza cyane bya zinc, aluminium na chromate.Igicapo kimaze guteshwa agaciro no kurasa hejuru, igipfundikizo kijugunywe hamwe na Dacromet.Ipfunyika ya Dacromet ni ubwoko bwamazi ashingiye kumazi, kugirango atunganyirize ibice byicyuma nyuma yo gushiramo amavuta cyangwa gutera spray yo kwisiga mu mavuta, mu itanura rikiza, hamwe na firime 300 yo guteka, kugirango ikore zinc, aluminium, chromium, idafite umubiri.
Mugihe cyo gukira, amazi nibintu kama (selulose) mubifuniko bihindagurika mugihe bishingiye kuri okiside yumunyu wa chromium uhenze cyane mubinyobwa byababyeyi ba dacromet, hanyuma umunyu wa chromium wa Fe, Zn na Al ukorwa nyuma ya reaction y'urupapuro rumwe rwa zinc hamwe na aluminiyumu yamashanyarazi hamwe na electrode nini mbi ishobora kuba ifite matrise.Kuberako igice cya membrane cyakozwe nyuma yuburyo butaziguye hamwe na matrix, igifuniko kirahuzagurika cyane.Mu bidukikije byangirika, igipfundikizo gikora selile nyinshi za galvanic, ni ukuvuga ko kibanza gukosora imyunyu mibi ya Al na Zn kugeza igihe ikoreshejwe mbere yuko iba. birashoboka kwangirika muri matrix ubwayo.
