235 amashidi othayela
Incazelo emfushane:
Ishidi elakhiwe ngamapulangwe libhekisela epuleti lensimbi elinongqimba lwezinc ngaphezulu.I-galvanizing iyindlela yokuvimbela ukugqwala kwezomnotho nephumelelayo evame ukusetshenziswa.Cishe ingxenye yokukhiqizwa kwe-zinc emhlabeni isetshenziswa kule nqubo.
Ingahlukaniswa ngezigaba ezilandelayo ngokuya ngokukhiqiza nezindlela zokucubungula:
① Ipuleti lensimbi lediphu elishisayo.Ishidi lensimbi licwiliswa ekugezeni kwe-zinc encibilikisiwe ukuze ungqimba lwe-zinc lunamathele ebusweni balo.Njengamanje, inqubo eqhubekayo yokufaka ama-galvanizing isetshenziswa ikakhulukazi, okungukuthi, ipuleti lensimbi eligoqiwe licwiliswa ngokuqhubekayo kubhavu lokuncibilika kwe-zinc ukuze kwenziwe ipuleti lensimbi elinamandla;
② Ishidi lensimbi elihlanganisiwe.Lolu hlobo lwepuleti lensimbi lwenziwa futhi ngendlela yokucwilisa okushisayo, kodwa lushiselwa cishe kufike ku-500 ℃ ngokushesha ngemva kokuphuma emseleni ukwenza ifilimu yengxubevange ye-zinc nensimbi.Ishidi elinothayela linokunamathela okuhle kokunamathela kanye nokushisela;
③ Ishidi lensimbi elenziwe nge-electro.Ishidi lensimbi elakhiwe nge-electroplating linokusebenza okuhle.Kodwa-ke, ukugqoka kuncane futhi ukumelana nokugqwala akukuhle njengalokho kweshidi elishisayo lokucwilisa;
④ Uhlangothi olulodwa olupuletiwe kanye nohlangothi olukabili ishidi lensimbi elibi.Single side ipuleti lagalvanized steel, okungukuthi imikhiqizo lathanda kuphela ohlangothini olulodwa.Ikwazi ukuzivumelanisa nezimo kangcono kuneshidi elinamacala amabili elinamacala amabili e-welding, enamathelayo, ekwelashweni kwe-antirust kanye nasekucutshungulweni.Ukuze unqobe ubungozi bokungagqoki i-zinc kolunye uhlangothi, kunolunye uhlobo lweshidi likathayela elimbozwe ungqimba oluncane lwezinc ngakolunye uhlangothi, okungukuthi, ishidi elimpofu elinamaceleni amabili;
⑤ Ingxubevange, ishidi lensimbi eliyinhlanganisela.Yingxubevange eyenziwe nge-zinc nezinye izinsimbi ezifana ne-aluminium, umthofu ne-zinc, ngisho nepuleti lensimbi eliyinhlanganisela.Lolu hlobo lwepuleti yensimbi alugcini nje ngokusebenza okuhle kakhulu kwe-antirust, kodwa futhi lunokusebenza okuhle kokumboza;
Ngaphezu kwalokhu okuhlanu okungenhla, kukhona ipuleti lensimbi elinombala, ipuleti lensimbi lokunyathelisa elakhiwe ngensimbi, ipuleti lensimbi elakhiwe nge-PVC elaminethisiwe, njll. Nokho, okuvame ukusetshenziswa kakhulu kuseyipuleti likamalayini elishisayo.
Abakhiqizi abakhulu namazwe angenisayo:
① Izitshalo eziyinhloko zokukhiqiza zasekhaya: WISCO, Angang, Baosteel Huangshi, MCC Hengtong, Shougang, Panzhihua Iron nensimbi, Handan Iron nensimbi, Maanshan Iron nensimbi, Fujian Kaijing, njll;
② Amazwe amakhulu okukhiqiza angaphandle yiJapan, Germany, Russia, France, South Korea, njll.
