Umbhobho weNtsimbi oyiGalvanized DX51D
Umbhobho weNtsimbi oyiGalvanized
Umbhobho wentsimbi galvanized wenza metal etyhidiweyo kunye nentsimbi substrate reaction kwaye ivelisa umaleko ingxubevange ukuze substrate kunye ukutyabeka zombini.
I-Hot-dip galvanizing kuxa umbhobho wentsimbi uvuthwa kuqala, ukuze kususwe i-iron oxide phezu kombhobho wentsimbi, emva kokuchola, icocwe nge-ammonium chloride okanye i-zinc chloride isisombululo samanzi okanye i-ammonium chloride kunye ne-zinc chloride exutywe emanzini. iitanki zesisombululo, kwaye emva koko ithunyelwe kwiitanki zokutshiza ezishushu.
Emva kokugquma i-zinc yombhobho wensimbi, umaleko womphezulu uba yikristale kunye neenkcukacha, kwaye ukuchasana ne-rust corrosion kuba namandla, okunokukhusela ngokufanelekileyo umzimba wombhobho.
Emva kwe-asidi passivation, i-surface layer yenziwe ngemibala eyahlukeneyo enjengomhlophe, eluhlaza kunye nombala, obonakala uhle kakhulu kwaye unokuba nefuthe lokuhombisa.
Umaleko owenziwe ngegalvanized une-ductility entle kakhulu kwaye unokutsalwa ngokubanda kwaye ugobe ngaphandle kokonakalisa umaleko wegalvanized, okwaziyo ukumelana nokurusa kunye nokuhlwa kwaye ukwathandeka ngobuhle.
Izixhobo zokulwa nomlilo: Umbhobho wentsimbi oditshiweyo oshushu oditshiweyo onesikwere esichasene nomhlwa.Izibonelelo ezichasene ne-corrosion, ngoko ke isetyenziswa ngokubanzi kwimibhobho yomlilo.
Kule mihla, imibhobho yokubonelela umlilo ngokusisiseko yonke imibhobho yentsimbi.Ingaba inani elikhulu lemibhobho yomlilo okanye imibhobho yomlilo kwindawo engaphantsi, ngokusisiseko yonke imibhobho yegalvanized, kwaye emva koko uluhlu lwepeyinti lusetyenziswa kuluhlu lwangaphandle lwemibhobho ye-galvanized, kwaye leyo yimibhobho yomlilo ebomvu onokuthi uyenze. iyakwazi ukubona, eneneni zicutshungulwa ukusuka kumbhobho wentsimbi yesikwele owenziwe ngamagalvanized kunye nombhobho wentsimbi ojikelezileyo.
Imibhobho yoLwakhiwo
Ngokuqhelekileyo isetyenziswa kwiiprojekthi zentsimbi yesakhiwo, namhlanje ngaphandle kwezityalo ezininzi ze-scaffolding, i-scaffolding yangaphambili yonke isebenzisa umbhobho wentsimbi odityanisiweyo, kodwa umbhobho wentsimbi odityanisiweyo ulula kakhulu ukurusa, ukwenzela ukuba uphephe umhlwa kufuneka ugqunywe ngomaleko wepeyinti. le ngxaki, kule mihla, iiprojekthi ezininzi zesakhiwo sentsimbi entsha zonke zisebenza ngokukhawuleza umbhobho we-galvanized, ukuze ukwazi ukugcina ixesha kwaye ingasetyenziselwa ixesha elide.Iiprojekthi ze-welding ngokubanzi zisebenzisa umbhobho wentsimbi obhityileyo owenziwe ngamazimba oxande, oqhele ukuba nomgangatho ophantsi wamazwe ngamazwe, kunye nemimiselo yemibhobho yesikwere yentsimbi ayikho phezulu kakhulu.
Ngophuhliso olukhawulezayo lwesayensi kunye nobuchwepheshe kwilizwe lethu, itshiphu eshushu editshiweyo yentsimbi ejikelezileyo umbhobho wentsimbi ukhankanyiwe kwibala nawo ubanzi ngakumbi nangakumbi, kwaye kunokuthiwa kuqoqosho lwelizwe lonke lwemigca yemveliso eyahlukeneyo kunye namacandelo, anjalo. njengokwenza oomatshini, uthutho, ishishini leemoto, ishishini, oomatshini bezolimo, oomatshini bepetroleum njalo njalo kuthotho lweshishini lemveliso.Njengenye i-electro-galvanized zinc inokusetyenziswa kumandla weathom ye-athom kunye nezinye iindawo, kuphuhliso loqoqosho lwaseTshayina, ludlala ukubaluleka okubalulekileyo.Njengoko umbhobho wentsimbi ekhandiweyo unenkangeleko entle kunye nokuxhathisa kakuhle komhlwa, usetyenziswe ngokubanzi.
