Enqubweni yokukhiqiza lapho sisebenzisa I-zinc passivator emnyama , ngezinye izikhathi ungqimba lwefilimu lwe-workpiece luba nenkungu ngemva kokudlula, okungabangelwa yikhwalithi ephansi yokucwenga ye-workpiece, noma ukusetshenziswa okungafanele kwe-ejenti yokudlula, kodwa kungase kube ukuguga Uketshezi olukhiphayo olukhanyayo olubangelwe.
Njengoba imboni kaMnu. Li inomsebenzi omningi wokudlula ucezu lokusebenza, imvamisa yokubuyisela yesixazululo se-luminescent ngaphambi kokudlula incane uma kuqhathaniswa, futhi uMnu. Li ngephutha ukholelwa ukuthi umphumela omubi wesisombululo se-luminescent ubangelwa ukuhlushwa okuphansi kwe-nitric acid, ngakho-ke vele wengeze i-nitric acid. Yebo, ngenxa yalokho, kwavela ifilimu enombala wenkungu ngemva kokukhishwa komsebenzi. Kodwa-ke, uMnu. Li walungisa indawo yokugezela efaka uthayela kanye nebhavu yokugezela, kodwa ungqimba lwefilimu lomsebenzi lwalusenenkungu. Ngenxa yokubambezeleka okukhulu kokukhiqizwa, uMnu. Li washesha wacela onjiniyela be-Bigley ukuthi basize ekuxazululeni inkinga.
Ngemva kokuba onjiniyela be-Bigolly bephuthume esizeni, bahlole inqubo yokukhiqiza ngokusekelwe kokuhlangenwe nakho kwasensimini nezici zomkhiqizo i-trivalent chromium black zinc passivation agent. Ngemva kokuhlaziya i-galvanizing bath, isixazululo se-luminescent kanye nesisombululo se-passivation, bathola isisombululo se-luminescent I-concentration ye-zinc ion iphezulu kakhulu. Ngemva kokufaka uketshezi olukhipha ukukhanya ngolunye olusha, isenzakalo sefilimu enenkungu siyaxazululeka.
Ukuze kugwenywe lesi simo sokungaphumeleli ukuthi singaphinde senzeke, unjiniyela kaBigolly unxuse uMnu. Li ukuthi amiselele isixazululo se-luminescent ngesikhathi ngesikhathi senqubo yokukhiqiza, kanye nokugcwala kwama-zinc ion endaweni yokukhanya. Isixazululo akufanele sidlule i-5g/L, ngaphandle kwalokho ifilimu izolahleka ngemuva kokuthi i-workpiece idlulisiwe. Kuzovela umbala onenkungu.
Ngakho-ke, ohlelweni lokukhiqiza lokusebenzisa i-ejenti emnyama ye-zinc, kufanele futhi sinake ikhwalithi yesixazululo esikhanyayo. Enqubweni yokukhiqiza, ukuqinisa ukugcinwa nokuphathwa kwesisombululo se-zinc plating, isixazululo esikhanyayo kanye nesisombululo se-passivation singagwema ngokuphumelelayo ukubukeka kwama-workpieces. Ukwenzeka kwefilimu yombala wenkungu kunciphisa ukuvela kokwehluleka. Uma unentshisekelo kuma-agent amnyama e-zinc passivation, ungase ufise ukuxhumana nesevisi yamakhasimende e-Bigley ukuze uthole amasampula amahhala kanye nolwazi oluningiliziwe lwezobuchwepheshe!
Uma ufuna ukwazi okwengeziwe mayelana nokufaka ama-galvanizing, ungabheka " Izindaba Zemboni".
