Ukwahlukaniswa kweshidi likathayela ngokwezindlela zokukhiqiza nezindlela zokucubungula
① Ishidi lensimbi elicwebezelayo elishisayo.Ipuleti lensimbi elincanyana licwiliswa kubhavu we-zinc encibilikisiwe ukwenza ubuso balo bunamathele ongqimbeni lwezinc.Njengamanje, ikhiqizwa ikakhulukazi inqubo eqhubekayo yokufaka ama-galvanizing, okungukuthi, ipuleti lensimbi eligoqiwe licwiliswa ngokuqhubekayo kubhavu lokucwenga le-zinc elincibilikisiwe ukwenza ipuleti lensimbi elinamandla;
2 Ishidi lensimbi elihlanganisiwe.Lolu hlobo lwepuleti lensimbi lwenziwa futhi ngendlela ye-hot-dip, kodwa lushiselwa cishe ku-500 ℃ ngokushesha ngemva kokuba luphumile ethangini, ukuze lenze ingxubevange ye-zinc nensimbi.Ishidi elinothayela linokunamathela okuhle kokunamathela kanye nokushisela.
③ Ishidi lensimbi elenziwe ngogesi.Ishidi lensimbi elakhiwe ngendlela ye-electroplating linokusebenza okuhle.Kodwa-ke, ukumbozwa kuncane futhi ukumelana nokugqwala akukuhle njengalokho kweshidi likathayela lokucwilisa elishisayo.
④ Ipuleti lensimbi elinohlangothi olulodwa kanye nepuleti lensimbi enamacele amabili elihlukile.Ipuleti lensimbi eliseceleni elilodwa, okungukuthi, imikhiqizo efakwe ama-galvanized ohlangothini olulodwa kuphela.Mayelana nokushisela, ukunamathela, ukwelashwa kwe-antirust kanye nokucutshungulwa, inokuphinda isebenze kangcono kuneshidi elinezinhlangothi ezimbili.Ukuze unqobe isici sokungagqokwa ngakolunye uhlangothi, kunolunye uhlobo lweshidi likathayela elimbozwe ungqimba oluncane lwezinc ngakolunye uhlangothi, okungukuthi, ishidi elihlukanisayo elinezinhlangothi ezimbili.
⑤ Ingxubevange nepuleti lensimbi eliyinhlanganisela.Kuyipuleti lensimbi elenziwe nge-zinc nezinye izinsimbi ezinjengomthofu, i-zinc, ngisho nenhlanganisela eyinhlanganisela.Lolu hlobo lwepuleti yensimbi alugcini nje ngokusebenza okuhle kakhulu kokulwa nokugqwala, kodwa futhi lunomsebenzi omuhle wokumboza;Ngaphezu kwalezi zinhlobo ezinhlanu ezingenhla, kukhona ipuleti lensimbi elinombala, ipuleti lensimbi eliphrintiwe futhi elinamekwe, kanye nepuleti lensimbi elakhiwe nge-polyvinyl chloride.Kodwa-ke, okuvame ukusetshenziswa kakhulu kuseyishidi le-hot-dip galvanized.
