Ishidi eliphehliwe ipuleti lensimbi elinongqimba lwezinc olubekwe phezulu. I-galvanizing iyindlela eyongayo futhi ephumelelayo yokuvimbela ukugqwala evame ukusetshenziswa, futhi cishe ingxenye yokukhiqizwa kwe-zinc emhlabeni isetshenziswa kule nqubo.
Indima yeishidi likathayela
Ipuleti lensimbi elakhiwe ngensimbi elokuvikela ukugqwala ebusweni bepuleti lensimbi ukuze linwebe impilo yalo yesevisi, elimbozwe ngongqimba lwezinki lwensimbi ebusweni bepuleti lensimbi, ipuleti lensimbi elinezinki libizwa ngokuthi ipuleti elithathiwe.
Ukuhlukaniswa kweshidi elinothayela
Ngokusho kokukhiqiza kanye nezindlela zokucubungula zingahlukaniswa ngezigaba ezilandelayo:
①Ipuleti lensimbi elinediphu elishisayo. Insimbi yeshidi icwiliswa ethangini le-zinc elicibilikile ukuze ubuso bunamathele kungqimba lwensimbi ye-zinc sheet. Njengamanje, ikhiqizwa ikakhulukazi inqubo eqhubekayo yokufaka ama-galvanizing, okungukuthi, ukucwiliswa okuqhubekayo kwamapuleti ensimbi egoqiwe emathangini okuncibilika e-zinc ukuze enze amapuleti ensimbi;
② Ipuleti lensimbi elihlanganisiwe. Le nsimbi yensimbi nayo yenziwa ngokucwiliswa okushisayo, kodwa ngemva kokuba ithangi seliphumile, liyashisisa ngokushesha libe ngu-500 ° C ukuze likhiqize ifilimu yengxubevange ye-zinc nensimbi. Ishidi elinothayela linokunamathela okuhle kanye nokushisela kokunamathela.
③ Ipuleti lensimbi likagesi. Ipuleti lensimbi elakhiwe nge-electroplating linokusebenza okuhle. Kodwa-ke, ukumbozwa kuncane futhi ukumelana nokugqwala akukuhle njengalokho kweshidi likagesi lokucwilisa elishisayo.
④ Ipuleti lensimbi elinaceleni olulodwa nelinezinhlangothi ezimbili. Insimbi enezinsimbi ezinohlangothi olulodwa, okungukuthi, imikhiqizo efakwe ama-galvanized ohlangothini olulodwa kuphela. Ikwazi ukuzivumelanisa nezimo kangcono kuneshidi elinamaceleni amabili elinothayela ekushiseleni, enamathelayo, ekwelashweni okulwa nokugqwala, ukucutshungulwa nokunye. Ukuze unqobe ukushiyeka kwe-zinc engagcotshiwe ngakolunye uhlangothi, kuneshidi likathayela elimbozwe ungqimba oluncane lwe-zinc ngakolunye uhlangothi, okungukuthi, ishidi elihlukanisayo eliphindwe kabili;
⑤ Ingxubevange, ipuleti lensimbi eliyinhlanganisela. Kuyipuleti lensimbi elenziwe nge-zinc nezinye izinsimbi ezifana ne-aluminium, umthofu, i-zinc, ngisho nokufakwa kwenhlanganisela. Le nsimbi yensimbi ayinayo kuphela ukusebenza okuhle kakhulu kokugqwala, kodwa futhi inokusebenza okuhle kokumboza;
Ngaphezu kwalezi zinhlobo ezinhlanu ezingenhla, kukhona ipuleti lensimbi elinombala, ipuleti lensimbi eliphrintiwe eliphrintiwe, i-polyvinyl chloride elaminethiwe ipuleti lensimbi nokunye. Kodwa evame ukusetshenziswa namanje hot dip lathi ishidi.
Ukubukeka kweshidi elinothayela
Isimo esingaphezulu: Ngenxa yezindlela zokwelashwa ezihlukene enqubweni yokucwenga, isimo esingaphezulu sepuleti likathayela sihlukile, njengezimbali ezijwayelekile ze-zinc, izimbali ezinhle ze-zinc, izimbali eziyisicaba ze-zinc, izimbali ze-zinc kanye ne-phosphating surface.
