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 Inkqubo yokuvelisa i-Zinc Into yokugquma ipleyiti yentsimbi imele intsimbi ediphu eshushu.
Intsimbi yentsimbi ekhuniweyo kukuthintela umphezulu wentsimbi ukuba ungagqwali kwaye wandise ubomi bayo benkonzo. Umphezulu wepleyiti yentsimbi ugqunywe ngumaleko we-zinc yensimbi, ebizwa ngokuba yi-galvanized steel plate.
Ngokweendlela zokuvelisa kunye nokucubungula, inokwahlulwa ngokwezi ndidi zilandelayo:
①Ishiti lentsimbi yediphu eshushu. I-sheet sheet ifakwe kwi-bath zinc etyhidiweyo, kwaye ishidi le-zinc linamathele kumphezulu walo. Okwangoku, iveliswa ngokukodwa ngenkqubo eqhubekayo yokufaka i-galvanizing, oko kukuthi, ipleyiti yensimbi eyenziwe ngokuqhubekayo ngokuntywiliselwa kwiiplate zetsimbi ezigoqiweyo kwi-tank yokucoca apho i-zinc inyibilika;
②Ishiti lentsimbi edibeneyo. Olu hlobo lwepleyiti yentsimbi lwenziwa 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.
