Ishidi elinothayela libhekisela eshidini lensimbi elifakwe ungqimba lwezinc ngaphezulu. I-galvanizing iyindlela evame ukusetshenziswa eyongayo futhi ephumelelayo yokuvimbela ukugqwala, futhi cishe ingxenye yokukhiqizwa kwe-zinc emhlabeni isetshenziswa kule nqubo.
Igama lesiShayina I-Zinc eboshwe ngensimbi Igama langaphandle Insimbi eboshwe I-Zinc Umsebenzi Indlela yokunqanda Isigaba Inqubo yokukhiqiza i-Zinc Into yokumbozwa kwepuleti lensimbi imelela insimbi ewuketshezi ediphu eshisayo.
Ipuleti lensimbi elikhangayo elokuvikela ingaphezulu lepuleti lensimbi ukuthi lingagqwali futhi lelule impilo yalo yesevisi. Ingaphezulu lepuleti lensimbi limbozwe ungqimba lwezinki lwensimbi, olubizwa nge-galvanized steel plate.
Ngokwezindlela zokukhiqiza nezindlela zokucubungula, ingahlukaniswa ngezigaba ezilandelayo:
① Ishidi lensimbi elidiphu elishisayo elishisayo. 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;
②Ishidi lensimbi elihlanganisiwe. 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 Ishidi lensimbi enama-electro-galvanized. Ishidi lensimbi elakhiwe ngendlela ye-electroplating linokusebenza okuhle. Kodwa-ke, ukugqoka kuncane, futhi ukumelana nokugqwala akukuhle njengalokho kweshidi elishisayo lokucwilisa;
④Insimbi 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;
⑤I-alloy neshidi lensimbi eliyinhlanganisela. 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:
①Izitshalo zokukhiqiza zasekhaya eziyinhloko: WISCO, Angang, Baosteel Huangshi, MCC Hengtong, Shougang, Pangang, Handan, Magang, Fujian Kaijing, njll.;
②Abakhiqizi abakhulu bakwamanye amazwe yiJapan, Germany, Russia, France, South Korea, njll.
