I-coil ye-galvanized, idipha ishidi lentsimbi kwibhafu ye-zinc etyhidiweyo ukuze ibambelele kwiphepha le-zinc ebusweni bayo.Okwangoku, inkqubo ye-galvanizing eqhubekayo isetyenziselwa imveliso, oko kukuthi, ipleyiti yentsimbi ibe ngumqulu wokucwiliswa okuqhubekayo ekunyibilikeni kwetanki yokucoca i-zinc eyenziwe ngepleyiti yentsimbi kunye ne-alloyed steel galvanized sheet.Le ntsimbi yentsimbi yenziwe ngediphu eshushu, kodwa ngoko nangoko emva komkhombe, ifudunyezwa malunga ne-500 ℃, ukuze yenze ifilimu yengxubevange ye-zinc kunye nentsimbi.Le khoyili ifakwe igalvanized ine-adhesion yokwambathisa elungileyo kunye ne-weldability.

Izinto zekhoyili ezenziwe ngegalvanized

a) Diphu eshushu ikhoyili yentsimbi.Ikhoyili yentsimbi encinci ifakwe kwitanki ye-zinc etyhidiweyo ukuze ubuso bayo bunamathele kwikhoyili yensimbi encinci ye-zinc.Okwangoku, inkqubo ye-galvanizing eqhubekayo isetyenziselwa ukuveliswa, oko kukuthi, ipleyiti yensimbi ibe ngumqulu wokucwiliswa ngokuqhubekayo kwi-tank yokucoca i-zinc eyenziwe nge-coil yensimbi;

b) Ikhoyili yentsimbi edityanisiweyo.Le coil yentsimbi yenziwa ngokukhutshwa kwamanzi ashushu, kodwa ngoko nangoko emva komkhombe, ifudunyezwa malunga ne-500℃, ukuze yenze ifilimu yealloyi ye-zinc kunye nentsimbi.Le khoyili yagalvanized inokuqina kakuhle kokwambathisa kunye nokuweldability; 

a) ikhoyili yentsimbi.Olu hlobo lwe-coil yensimbi ene-galvanized ine-machinability elungileyo nge-electroplating.Kodwa ukutyabeka kubhityile, ukuxhathisa umhlwa njengoko idiphu eshushu ikhoyili yagalvanized;

Ukusetyenziswa kwekhoyili yegalvanized

Inani elikhulu leekhoyili ezibhityileyo ezinamazinki zisetyenziswa ekwenzeni iimoto, isikhenkcisi, ulwakhiwo, umoya kunye nezixhobo zokufudumeza kunye nokwenziwa kwefenitshala.I-zinc plating ibe yindlela ebalulekileyo yokuthintela ukubola kwentsimbi, kungekhona nje ngokuba i-zinc inokwenza umaleko okhuselayo phezu komhlaba wentsimbi, kodwa nangenxa yokuba i-zinc inefuthe lokukhusela i-cathodic, xa i-zinc layer yonakele, isenokuthintela ukubola. i-corrosion yesiseko sentsimbi ngokukhuselwa kwe-cathodic. 

Ukucaciswa kwekhoyili eyenziwe ngegalati

Iimpawu zeekhoyili ezenziwe ngegalvanized ziqhelekileyo ubukhulu beshiti le-galvanized kwi-0.4 ~ 2.0.Ngokuqhelekileyo ngaphantsi kwe-0.4mm yezixhobo zentsimbi eziphantsi kukarhulumente azivelisi, ngokubanzi ukuveliswa kwezixhobo ezincinci zentsimbi zabucala, iinkcukacha eziqhelekileyo ziyi-0.35, 0.30, 0.28, 0.25, ngokubanzi zincinci ukuya ku-0.15, ngaphezu kwe-2.0mm ngenxa ye ubunzima bokulungisa, ngoko ke ngaphezu kwe-2.0 kunye nokunyuka kobunzima bexabiso buyenyuka.
