Imibhobho yentsimbi emnyamakwayeimibhobho ye-galvanizedzezona zimbini zezona zixhaphakileyo ezisetyenziselwa ukuthutha ulwelo kunye neegesi. Ngoko ke, yintoni umahluko phakathi kombhobho omnyama nombhobho we-galvanized.
Ukumelana nokugqwala
Umahluko ophambili phakathi kwemibhobho yentsimbi emnyama kunye nemibhobho ye-galvanized kukumelana nokugqwala.
Umbhobho wesinyithi omnyama wenziwa ngentsimbi ethambileyo. Unomxholo wekhabhoni ophantsi. Ukumelana nokugqwala kwentsimbi ethambileyo kunokomelezwa ngakumbi ngokongeza ikhabhoni.
Kwelinye icala, imibhobho egqunywe nge-galvanized igqunywe ngumaleko okhuselayo we-zinc. Inkqubo yokongeza umaleko we-zinc ibizwa ngokuba yi-galvanization, nto leyo eyenza imibhobho ibe neempawu ezifanelekileyo zokumelana nokugqwala okuphezulu.
Inkqubo yoMveliso
Omnye umahluko obalulekileyo phakathi kwemibhobho yesinyithi esimnyama kunye nemibhobho ye-galvanized unxulunyaniswa neenkqubo zayo zokwenza. Imibhobho yesinyithi esimnyama yenziwa ngokusolula intsimbi ibe yityhubhu engenamthungo okanye ngokunyanzela imiphetho kunye nokuzivala nge-weld.
Iipayipi ze-hot-dip galvanizing zenziwa ngepayipi yentsimbi emnyama kunye ne-zinc coating. Le nkqubo ibandakanya ukuhlamba ipayipi yentsimbi nge-asidi ukususa nayiphi na i-rust okanye i-oxidation, ukuyicoca ngesisombululo se-ammonium chloride, i-zinc chloride, okanye indibaniselwano yazo zombini ngaphambi kokuntywiliselwa kwi-hot-dip galvanizing bath.
Inkangeleko
Imibhobho yentsimbi emnyama imnyama xa ithelekiswa nemibhobho ye-galvanized. I-iron oxide eyenziwe ngexesha lokwenziwa kwayo yiyo ebangele ukuba ibonakale ingwevu. Imibhobho ye-galvanized ibonakala imhlophe njengesilivere ngenxa ye-galvanization. Ukwaleka kwe-zinc kubangela ukuba igqitywe kakuhle kwaye ibe semgangathweni ophezulu.
Izicelo
Zombini ezi ntlobo zemibhobho zineempawu ezahlukeneyo ezifanelekileyo kwiindlela ezithile zokusebenza. Isici esingenamthungo semibhobho yesinyithi esimnyama senza ukuba ibe yeyona ndlela ilungileyo nekhuselekileyo yokuthutha igesi yendalo kunye nepropane. Umbhobho wesinyithi odibeneyo omnyama awubizi nje kuphela, kodwa ukwalukhetho olufanelekileyo lokuhambisa igesi yendalo kwaye usetyenziselwa iinkqubo zokutshiza umlilo.
Imibhobho yentsimbi emnyama yaziwa ngokugqwala emanzini lula. Yiyo loo nto isebenzisa imibhobho ye-galvanized ekuthwaleni amanzi. Ngenxa yokuba inamandla okumelana nokugqwala, ingasetyenziselwa ukusetyenziswa ngaphandle nangaphandle nakwiindawo zoshishino ezininzi. Ukusetyenziswa kwayo kungabandakanya iintsimbi zangaphandle, iifreyimu ze-scaffolding, ucingo, imibhobho yamanzi amdaka, imiqondiso yendlela, kunye nokunkcenkceshela efama.
Ukuqina
Nangona kuyinyani ukuba intsimbi sele iyinto eqinileyo, imibhobho eyenziwe nge-galvanized inamandla angcono ngenxa yokwaleka kwe-zinc ekhuselayo.
Ukwaleka kwezinki kwandisa ubomi beepayipi ezigalelwe ngesinyithi ukuya kuthi ga kwiminyaka engama-40 okanye engama-50.
Kwelinye icala, imibhobho yentsimbi emnyama ayigqunywanga kwaye ngenxa yoko ayihlali ixesha elide. Ukongeza, amanzi ayayidlakaza le mibhobho ngokulula.
Ixabiso
Imibhobho yesinyithi emnyama ibiza kancinci kunemibhobho ye-galvanized. Oku kungenxa yokungabikho kwe-zinc coating. Endaweni yoko, imibhobho yesinyithi emnyama igqunywe yi-iron oxide ngexesha lenkqubo yokwenziwa. Cinga ngokukhetha imibhobho yesinyithi emnyama kunemibhobho ye-galvanized ukuba ucinga ngebhajethi kwaye ukuba ukuhlala ixesha elide akuyonto iphambili ocinga ngayo.
Isigqibo sokugqibela kufuneka sixhomekeke kwinto efunekayo kwiprojekthi.
