La dhajiyay 2018-08-13Mabda'a daaweynta dusha sare ee Dacromet waa in la go'doomiyo isdhexgalka ka dhexeeya biyaha, oksijiinta iyo birta si loo helo saameyn antiseptik ah oo xooggan.Mabda'a badanaa waa iskaashiga saddex waji ilaalin ah.
Saamaynta xannibaadda: Lakabyada Zinc iyo aluminium ee dahaarka leh ee daahan ku dhex jira ayaa ku dul wareegaya oogada birta si ay u sameeyaan lakabka difaaca ee ugu horreeya, kaas oo ka horjoogsanaya dhexdhexaadiyaha daxalka ah sida biyaha iyo ogsijiinta in ay la xidhiidhaan substrate-ka, taas oo ciyaaraysa saamaynta go'doominta tooska ah ee tooska ah.
Passivation: In habka daaweynta daahan ee chromic acid leh zinc, budada aluminium iyo saldhigga birta Dacromet, filimka passivation ka sameeyay dusha sare ee falcelinta kiimikada, filimka passivation ma u nugul falcelinta daxalka, iyo sidoo kale u dhaqmo sida caqabad.Ficilka warbaahinta daxalka ah, oo ay weheliso saamaynta xannibaadda, waxay bixisaa difaac laba lakab ah oo xoojiya saamaynta go'doominta jirka.
Ilaalinta Cathodic: Tani waa saamaynta ugu muhiimsan ee ilaalinta.Sida mabda'a lakabka galvanized, ilaalinta cathodic waxaa lagu dabaqaa substrate-ka lakabka kiimikaad iyadoo la huraynayo anode.
Dhinaca kale, saddexdan nooc ee ilaalintu waxay dahaadhaan saamaynta daxalka ah ee dhexdhexaadka ah ee birta.Dhinaca kale, substrate-ku waa koronto ahaan daxalaystay, la yaabna ma laha in ay jiraan dhowr jeer saamaynta ilaalinta ee zinc-dhaqameedka elektiroonigga ah.
