Ukwelashwa kwendawo kuyindlela yokwakha ungqimba olungaphezulu olunezici zemishini, zomzimba, nezamakhemikhali ezihlukile ezintweni eziyisisekelo.
Umgomo wokwelashwa kwendawo ukwanelisa izidingo zomsebenzi ezihlukile zomkhiqizo zokumelana nokugqwala, ukumelana nokuguguleka, ukuhlobisa, nezinye izici. Ukugaya ngomshini, ukwelashwa ngamakhemikhali, ukwelashwa ngokushisa kwendawo, kanye nokufutha indawo kungenye yezindlela zethu zokwelapha indawo ezisetshenziswa kakhulu. Inhloso yokwelashwa kwendawo ukuhlanza, ukushanela, ukususa imfucuza, nokususa isikali endaweni yokusebenza. Sizofunda inqubo yokwelashwa kwendawo namuhla.
Ukufaka i-vacuum electroplating, ukufaka i-electroplating, ukufaka i-anodizing, ukupholisha nge-electrolytic, ukuphrinta ama-pad, ukufaka i-galvanizing, ukumboza ngempuphu, ukuphrinta kokudlulisa amanzi, ukuphrinta kwesikrini, i-electrophoresis, kanye nezinye izindlela zokwelapha ubuso zivame ukusetshenziswa.
1. Ukufakwa kwe-electroplating nge-vacuum
Isenzakalo sokufakwa kwezinto ezibonakalayo yi-vacuum plating. Izinto eziqondiwe zihlukaniswe ngama-molecule amuncwa izinto eziqhuba umoya ukuze kukhiqizwe ungqimba olufana nolubushelelezi lwensimbi yokulingisa lapho igesi ye-argon ifakwa esimweni se-vacuum bese ishaya izinto eziqondiwe.
Izinto ezisebenzayo:
1. Izinto ezahlukahlukene, okuhlanganisa izinsimbi, ama-polymer athambile naqinile, izinto ezihlanganisiwe, izinto zobumba, kanye nengilazi, zingafakwa i-vacuum plate. I-aluminium yinto evame ukufakwa i-electroplated, ilandelwe yisiliva nethusi.
2. Ngenxa yokuthi umswakama ezintweni zemvelo uzothinta indawo ye-vacuum, izinto zemvelo azifaneleki ukufakwa kwe-vacuum plating.
Izindleko zenqubo: Izindleko zomsebenzi zokufaka i-vacuum plating ziphakeme impela ngoba umsebenzi kumele ufafazwe, ulayishwe, uthululwe, futhi uphinde ufafazwe. Kodwa-ke, ubunzima kanye nobuningi bomsebenzi nakho kudlala indima ezindleleni zomsebenzi.
Umthelela emvelweni: Ukufaka i-vacuum electroplating kubangela umonakalo omncane emvelweni njengokufafaza.
Ngosizo lwamandla kagesi, ama-athomu ento yokusebenza ecwiliswe ku-electrolyte aguqulwa abe ama-ion futhi asuswe ebusweni ngesikhathi senqubo ye-electrochemical "ye-electroplating," esusa ama-burrs amancane futhi ikhanyise ubuso bento yokusebenza.
Izinto ezisebenzayo:
1. Iningi lezinsimbi lingapholishwa nge-electrolytic, kanti ukupholishwa kobuso bensimbi engagqwali kuyiyona ndlela ethandwa kakhulu (ikakhulukazi ngensimbi engagqwali ye-nuclear grade austenitic).
2. Akunakwenzeka ukupolisha izinto eziningi nge-electrolytic ngesikhathi esisodwa noma ngisho nangesixazululo esifanayo se-electrolytic.
izindleko zokusebenza: Ngenxa yokuthi ukupholisha nge-electrolytic empeleni kuwumsebenzi ozenzakalelayo ngokuphelele, izindleko zabasebenzi zincane kakhulu. Umthelela emvelweni: Ukupholisha nge-electrolytic kusebenzisa amakhemikhali ambalwa ayingozi. Kulula ukuyisebenzisa futhi kudinga amanzi amancane ukuze kuqedwe umsebenzi. Ngaphezu kwalokho, kungavimbela ukugqwala kwensimbi engagqwali futhi kwandise izimfanelo zensimbi engagqwali.
3. Indlela yokuphrinta iphedi
Namuhla, enye yezindlela zokunyathelisa ezikhethekile ezibaluleke kakhulu ikhono lokunyathelisa umbhalo, ihluzo, kanye nezithombe ebusweni bezinto ezinezimo ezingavamile.
Cishe zonke izinto zingasetshenziswa ekuphrinteni amaphedi, ngaphandle kwalezo ezithambile kuneziphephedi ze-silicone, kufaka phakathi i-PTFE.
Izindleko zabasebenzi eziphansi kanye nezokubumba zihlotshaniswa nenqubo.
Umthelela emvelweni: Le nqubo inomthelela omkhulu emvelweni ngoba isebenza kuphela ngoyinki oncibilikayo, owenziwe ngamakhemikhali ayingozi.
4. inqubo yokufaka i-zinc
indlela yokuguqula ubuso emboza izinto zensimbi ze-alloy ungqimba lwe-zinc ukuze kube nezakhiwo ezinhle nezilwa nokugqwala. Njengoba iwungqimba oluvikelayo lwe-electrochemical, ungqimba lwe-zinc olusebusweni lungavimba ukugqwala kwensimbi. Ukugaywa kwe-galvanizing kanye nokugaywa kwe-hot-dip yizindlela ezimbili ezisetshenziswa kakhulu.
Izinto ezingasetshenziswa: Ngenxa yokuthi inqubo yokwenza i-galvanizing incike kubuchwepheshe bokubopha ngensimbi, ingasetshenziswa kuphela ukwelapha ubuso bensimbi nensimbi.
Izindleko zenqubo: izindleko zomjikelezo omfushane/zomsebenzi ophakathi nendawo, azikho izindleko zesikhunta. Lokhu kungenxa yokuthi ikhwalithi yobuso bomsebenzi incike kakhulu ekulungisweni kobuso okwenziwe ngaphambi kokufakwa kwe-galvanizing.
Umthelela Wezemvelo: Inqubo yokufaka i-galvanizing inethonya elihle emvelweni ngokwandisa impilo yesevisi yezingxenye zensimbi ngeminyaka engama-40-100 nokuvimbela ukugqwala nokugqwala kwento yokusebenza. Ngaphezu kwalokho, ukusetshenziswa okuphindaphindiwe kwe-zinc ewuketshezi ngeke kuholele emfucumfucwini yamakhemikhali noma ebonakalayo, futhi into yokusebenza ehlanganisiwe ingabuyiselwa ethangini lokufaka i-galvanizing uma impilo yayo yokusebenza isidlulile.
inqubo ye-electrolytic yokufaka ungqimba lwefilimu yensimbi ezindaweni zezingxenye ukuze kuthuthukiswe ukumelana nokuguguleka, ukuhanjiswa kwamandla, ukubonakaliswa kokukhanya, ukumelana nokugqwala, kanye nobuhle. Izinhlamvu zemali eziningi nazo zine-electroplating engqimbeni yazo yangaphandle.
Izinto ezisebenzayo:
1. Iningi lezinsimbi lingafakwa i-electroplated, nokho ubumsulwa nokusebenza kahle kwe-plated kuyahlukahluka phakathi kwezinsimbi ezahlukahlukene. Phakathi kwazo, i-tin, i-chromium, i-nickel, isiliva, igolide, kanye ne-rhodium yizona ezivame kakhulu.
2. I-ABS yinto evame kakhulu ukufakwa ngogesi.
3. Ngenxa yokuthi i-nickel iyingozi esikhumbeni futhi iyacasula, ayikwazi ukusetshenziselwa ukufaka noma yini ethinta isikhumba nge-electroplate.
Izindleko zenqubo: azikho izindleko zesikhunta, kodwa izinto ezidingekayo ukulungisa izingxenye; izindleko zesikhathi ziyahlukahluka kuye ngokushisa nohlobo lwensimbi; izindleko zomsebenzi (eziphakathi nendawo kuya phezulu); kuye ngohlobo lwezingcezu zeplati ngayinye; isibonelo, izitsha zeplati kanye nobucwebe kudinga izindleko zomsebenzi eziphezulu kakhulu. Ngenxa yezindinganiso zayo eziqinile zokuqina nobuhle, iphathwa ngabasebenzi abaqeqeshiwe kakhulu.
Umthelela emvelweni: Ngenxa yokuthi inqubo yokufakelwa kwe-electroplating isebenzisa izinto eziningi eziyingozi, ukuphambukisa nokukhipha ngochwepheshe kuyadingeka ukuqinisekisa ukuthi umonakalo ongokwemvelo mncane.
