Kuthunyelwe ku 2018-05-23Umphumela wokuvikela we-dacromet layer ku-matrix yensimbi ungafingqwa ngale ndlela elandelayo:
1. Umphumela wokuvimbela: ngenxa yokugqagqana kwengqimba ye-zinc ne-aluminium, inqubo yokufinyelela ku-matrix yemidiya yokugqwala efana namanzi nomoya-mpilo ingavinjelwa.
2. I-Passivation: ngenqubo ye-dacro, i-chromic acid ihlangana ne-zinc, i-aluminium powder kanye nensimbi ye-matrix ukukhiqiza ifilimu eqinile ye-passivation, futhi le filimu ye-passivation inokumelana nokugqwala okuhle.
3. Ukuvikelwa kwe-Cathodic: umphumela oyinhloko wokuvikela we-zinc-alumina coating ufana ne-zinc coating, okuwukuvikela kwe-cathodic ye-substrate.
I-Changzhou junhe zinc chrome dacromet coating iwuhlobo lwesayensi nobuchwepheshe be-zinc powder, i-aluminium powder, i-chromic acid namanzi akhishwe njenge-deionized njengokwakhiwa okuyinhloko kohlobo olusha lwe-anticorrosive coating, ingaphezulu lombala owodwa, isiliva nesiliva kuphela, ayifaneleki isidingo somuntu ngamunye sokuthuthukiswa kwemboni yezimoto.Kodwa-ke, imibala ehlukene ingatholakala ngokucubungula ngemuva kokucubungula noma ukuhlanganiswa okuhlanganisiwe ukuze kuthuthukiswe umhlobiso nokuhambisana kwezingxenye zeloli.
