Amathiphu ayisisekelo: ama-alloys e-zinc asetshenziswa kakhulu endlini yokugezela, izikhwama, izicathulo nezesekeli, ngenxa yokunethezeka kwayo, ipulasitiki, izindleko eziphansi nokusebenza kahle okuphezulu.
I-Zinc alloy isetshenziswa kabanzi ku-sanitary ware, izikhwama, izicathulo nezesekeli zokugqoka ngenxa yokwakheka kwayo okulula, ipulasitiki eqinile, izindleko eziphansi nokusebenza kahle kokucubungula okuphezulu.Kodwa-ke, inkinga yokuqhuma kwe-zinc alloy (i-electroplating; ukufafaza) ibilokhu ikhathaza abangane bezimboni ze-hardware namafekthri e-electroplating.
Okuhlangenwe nakho kwe-zinc alloy foaming ezimbonini ze-electroplating zezimboni eziningana ze-hardware kufinyezwa kanjena:
1. Ekuqaleni kokuklanywa kwemikhiqizo ye-zinc alloy, kufanele sicabangele ukulungiselelwa kwechweba lokudla, i-slag discharge port kanye ne-exhaust port yesikhunta.Ngenxa yokuthi indlela yokugeleza yesiqeshana sokusebenza ngokuphakela nokukhipha i-slag ibushelelezi, akukho ukuvaleka komoya, akukho amabala amanzi, awekho amabhamuza amnyama, okuthinta ngokuqondile ukuthi i-electroplating elandelayo iyabhavumula.Indawo yokusebenza enokuphakelwa okufanelekayo kanye ne-slag discharing die casting inendawo ebushelelezi, ukukhanya okumhlophe, futhi ayinawo amabala amanzi.
2. Ekuthuthukisweni kwesikhunta, kufanele futhi sicabangele i-tonnage nokucindezela komshini wokufaka isikhunta.Sihlangabezane nomcimbi wama-20-30% wamabhamuza ngemva kwe-zinc alloy electroplating.Ifektri yehadiwe Umngane ukuhlolwa kokuqala kwembumbulu, nezingcezu eziyi-8 zesikhunta, nendlela yokuxazulula inkinga ye-20-30% ngaphambi kokukhipha amagwebu, futhi ekugcineni uvimbele isikhunta izingcezu ezi-4, futhi ushintshe zibe izingcezu ezi-4 zesikhunta.
3. Isixazululo se-calendering, i-polish paste kanye nesendlalelo se-oxide endaweni yokwelashwa kwangaphambili ayihlanzwa, futhi ingaphezulu le-workpiece emva kwe-calendering nokupholishwa kukhanya.Izisebenzi eziningi ekucushweni kwezitshalo zezitshalo ze-electroplating zikhetha ngokunganaki, okuholela ekutheni i-ejenti enamathiselwe ye-calendering engaphezulu ingahlanzwa, futhi kuvela amabhamuza amade.Ukwengeza, kunobudlelwane obukhulu phakathi kwama-agent e-calendering akhethwe yisitshalo se-calendering ne-polishing, futhi ama-surfactants kwamanye ama-calendering agents anzima kakhulu ukuwageza.
4. Ngaphambi kokuthi umkhiqizo ungene kubhavu yokucwenga yethusi ene-alkaline, kusekhona ifilimu ye-oxide (ifilimu yokuqoqa) phezu kwendawo yokusebenza.Ifilimu yokususa i-wax namafutha ayiphathwa ngokuphelele.Ngakho-ke, kubaluleke kakhulu ukususa ifilimu.Eminyakeni yokuqala, ingabuye isuswe nge-anti staining salt.Manje, akuvunyelwe ukukhipha amanzi angcolile aqukethe usawoti oqeda amabala.Kutuswa ukusebenzisa impushana yokususa ifilimu i-lj-d009, enomphumela ongcono kunosawoti oqeda amabala, futhi ingasusa ungqimba lwe-nickel, futhi ukukhishwa kwe-COD kuhlangabezana nezindinganiso zikazwelonke zamazwe ngamazwe.
5. Kukhona izinto eziningi eziphilayo kanye nokungcola endaweni yokugeza ye-alkaline yethusi, futhi i-cyanide yamahhala ayikho kububanzi.Hlola ukwakheka kwethangi le-alkaline lethusi ukuze ubone ukuthi i-sodium cyanide iphansi yini noma i-sodium hydroxide iphezulu!Uma ungeza ukukhanyisa ngokucophelela, i-brightener iphezulu, futhi ukuhlanzwa kwe-tank yethusi ye-alkali kubaluleke kakhulu.Kunconywa ukuthi ukwelashwa kwe-carbon kufanele kwenziwe kanye njalo ezinsukwini ezingu-3-5
6. I-conductivity yesilinda se-alkali yethusi nayo ibaluleke kakhulu.Ukuthi i-anode incibilika ngokujwayelekile nokuthi i-anode copper plate yanele yini kuzoholela ekuqhumeni
7. Imikhiqizo ye-zinc alloy blister lapho iphuma kuhhavini;kungase kubangelwe izinga lokushisa likahhavini elingalingani, okungukuthi, izinga lokushisa eliphakeme kakhulu.Ngenxa yokuthi i-die casting ayiqinile, kulula ukufaka i-asidi emanzini amabala kanye nama-trakoma we-zinc alloy.Ngisho noma kukhona ukumbozwa kwendawo, i-asidi ne-zinc isazoba nokusabela kwamakhemikhali, ikhiqize inani elikhulu le-hydrogen h.Lapho umfutho womoya ngaphakathi uphakeme kunokucindezela komkhathi ngokwezinga elithile, futhi izinga lokushisa eliphezulu lizoveza amabhamuza
