Ipuleti lensimbi elakhiwe ukuvikela ingaphezulu lensimbi ukuthi lingagqwali futhi lelule impilo yalo yesevisi, futhi ingaphezulu lepuleti lensimbi limbozwa ungqimba lwezinki lwensimbi.
Ngokwezindlela zokukhiqiza nezindlela zokucubungula, ingahlukaniswa ngezigaba ezilandelayo:
1 Ishidi lensimbi elishisayo-dip. Insimbi yeshidi icwiliswa ekugezeni kwe-zinc encibilikisiwe, futhi ishidi le-zinc linamathele ebusweni balo. Njengamanje, ikhiqizwa ikakhulukazi inqubo eqhubekayo yokufaka ama-galvanizing, okungukuthi, ipuleti lensimbi elenziwe ngothayela lenziwa ngokucwiliswa ngokuqhubekayo amapuleti ensimbi agingqiwe ethangini lokucwenga lapho kuncibilika khona i-zinc;
2 I-alloy galvanized steel sheet. Lolu hlobo lwepuleti lensimbi lwenziwa futhi ngendlela ye-hot-dip, kodwa ngemva kokuba seliphumile ethangini, lishiselwa ku-500 ℃ ngokushesha ukuze lenze ifilimu yengxubevange ye-zinc nensimbi. Leli shidi elinothayela linenamathela kahle ngopende kanye nokushisela;
3 Electro-galvanized steel sheet. Ishidi lensimbi elakhiwe ngendlela ye-electroplating linokusebenza okuhle. Kodwa-ke, ukugqoka kuncane, futhi ukumelana nokugqwala akukuhle njengalokho kweshidi elishisayo lokucwilisa;
4 Insimbi enothayela enohlangothi olulodwa nezinhlangothi ezimbili. Ishidi lensimbi eliseceleni elilodwa, okungukuthi, umkhiqizo ofakwe ama-galvanized ohlangothini olulodwa kuphela. Ekushiseleni, ekudwebeni, ekwelapheni okunqanda ukugqwala, ekucubunguleni, njll., kunokuvumelana nezimo kangcono kuneshidi elinamacele amabili elithathiwe. Ukuze unqobe ubungozi bokuthi uhlangothi olulodwa alugcotshwanga nge-zinc, kunelinye ishidi likathayela elimbozwe ungqimba oluncane lwezinc ngakolunye uhlangothi, okungukuthi, ishidi elihlukanisayo elinamacala amabili;
5 Ingxubevange, ishidi lensimbi eyinhlanganisela. Yenziwe nge-zinc nezinye izinsimbi ezifana ne-aluminium, umthofu, i-zinc, njll. ukwenza ama-alloys noma ngisho namapuleti ensimbi ayinhlanganisela. Lolu hlobo lwepuleti yensimbi alugcini nje ngokusebenza okuhle kakhulu kokulwa nokugqwala, kodwa futhi lunomsebenzi omuhle wokumboza;
Ngaphezu kwalezi zinhlobo ezinhlanu ezingenhla, kukhona namashidi ensimbi anombala, amashidi ensimbi aphrintiwe futhi apendwe apendwe, namashidi ensimbi enziwe ngelayini e-PVC. Kodwa okuvame ukusetshenziswa kakhulu kuseyishidi le-hot-dip galvanized.
Izitshalo eziyinhloko ezikhiqizayo namazwe akhiqizayo avela kwamanye amazwe:
Izitshalo ezi-1 eziyinhloko zokukhiqiza ezifuywayo: I-Wuhan Iron and Steel, i-Anshan Iron and Steel, i-Baosteel Huangshi, i-MCC Hengtong, i-Shougang, i-Panzhihua Iron and Steel, i-Handan Iron and Steel, i-Maanshan Iron and Steel, i-Fujian Kaijing, njll.;
2 Abakhiqizi abakhulu bakwamanye amazwe yiJapan, Germany, Russia, France, South Korea, njll.
