Iphepha le-galvanized libhekisela kwiphepha lentsimbi elifakwe kwi-zinc phezu komhlaba.Igalvanizing yindlela esetyenziswa rhoqo yezoqoqosho nesebenzayo yokuthintela umhlwa, kwaye malunga nesiqingatha semveliso ye-zinc yehlabathi isetyenziswa kule nkqubo.
Igama lesiTshayina I-Zinc eqatywe intsimbi Igama langaphandle I-Zinc eqatywe intsimbi Umsebenzi Indlela yokulwa ne-Antirust Udidi lwenkqubo yokuvelisa i-Zinc Into yokugquma ngepleyiti yemveliso imele intsimbi ediphu eshushu.
Intsimbi yentsimbi ekhuniweyo kukuthintela umphezulu wentsimbi ukuba ungagqwali kwaye wandise ubomi bayo benkonzo.Umphezulu wepleyiti yentsimbi ugqunywe ngumaleko wentsimbi ye-zinc, ebizwa ngokuba yi-galvanized steel plate.
Ngokweendlela zokuvelisa kunye nokucubungula, inokwahlulwa ngokwezi ndidi zilandelayo:
①Ishiti lentsimbi yediphu eshushu.I-sheet sheet ifakwe kwindawo yokuhlambela ye-zinc etyhidiweyo, kwaye ishidi le-zinc linamathele kumphezulu walo.Okwangoku, iveliswa ngokukodwa ngenkqubo eqhubekayo yokufaka i-galvanizing, oko kukuthi, ipleyiti yensimbi eyenziwe ngokuqhubekayo ngokuntywiliselwa iiplate zetsimbi ezigoqiweyo kwitanki yokutshiza apho i-zinc inyibilika;
②Ishiti lentsimbi edibeneyo.Olu hlobo lwepleyiti yentsimbi lwenziwe ngendlela yokudipha eshushu, kodwa emva kokuba iphumile etankini, ifudunyezwa malunga ne-500 ℃ ngoko nangoko ukwenza ifilimu yengxubevange ye-zinc kunye nentsimbi.Eli phepha lifakwe igalvanized linepeyinti yokuncamathelisa kakuhle kunye ne-weldability;
③ Ishiti lentsimbi ye-Electro-galvanized.Ishiti letsimbi elakhiweyo eliveliswe yindlela ye-electroplating inokusebenza kakuhle.Nangona kunjalo, i-coating incinci, kwaye ukuxhathisa kwe-corrosion ayilunganga njengephepha le-galvanized sheet;
④Icala elinye kunye necala eliphindwe kabini lokwahluka kwentsimbi.Ishiti lentsimbi enecala elinye, oko kukuthi, imveliso ephekwe kwicala elinye kuphela.Kwi-welding, ukupeyinta, unyango oluchasene ne-rust, processing, njl., lunokuguquguquka okungcono kunamacangca aphindwe kabini.Ukuze ukoyise ukusilela ukuba elinye icala aligqunywanga nge-zinc, kukho elinye iphepha elinezinki eligqunywe ngomaleko obhityileyo we-zinc kwelinye icala, oko kukuthi, iphepha elinezinki eziphindwe kabini;
⑤I-alloy kunye ne-composite steel sheet.Yenziwe nge-zinc kunye nezinye iintsimbi ezifana ne-aluminiyam, ilothe, i-zinc, njl njl ukwenza i-alloys okanye iipleyiti zentsimbi ezidibeneyo.Olu hlobo lwepleyiti yentsimbi alunamsebenzi obalaseleyo wokuchasana nomhlwa kuphela, kodwa lunokusebenza kakuhle kokwambathisa;
Ukongeza kwezi ntlobo zintlanu zingasentla, kukwakho namaphepha entsimbi afakwe umbala, aprintiweyo aza apeyintwa amashiti entsimbi apheyintiweyo, kunye namashiti esinyithi enziwe ngelamine ePVC.Kodwa esona sixhaphakileyo sisetyenziswa iseyi-hot-dip galvanized sheet.
Izityalo eziphambili kunye namazwe avelisa kumazwe angaphandle:
①Izityalo eziphambili zemveliso yasekhaya: WISCO, Angang, Baosteel Huangshi, MCC Hengtong, Shougang, Pangang, Handan, Magang, Fujian Kaijing, njl.;
②Abona bavelisi abaphambili bangaphandle yiJapan, iJamani, iRussia, iFrance, iSouth Korea, njl.
