I-Hot Dip Galvanized Channel Steel
Umgomo Wongqimba Olunwetshiwe Lwensimbi Yensimbi Eshisayo Yakhiwa izinyathelo ezintathu ze-zinc esimweni soketshezi lokushisa eliphezulu:
1. Ingaphezulu lesisekelo sensimbi lichithwa yi-zinc liquid ukuze kwakhiwe ungqimba lwesigaba se-zinc-iron alloy;
2. Ama-ion e-zinc ongqimba lwe-alloy aqhubekela phambili asakazeka ku-substrate ukuze akhe ungqimba oluncibilikayo lwe-zinc-iron;
3. Ingaphezulu le-alloy layer lizungezwe ungqimba lwezinc.
(1) Inongqimba oluqinile lwezinc oluqinile futhi oluminyene olumboza ingaphezulu lensimbi, olungagwema ukuthintana nengxenye yensimbi nganoma yisiphi isixazululo esonakalisayo futhi ivikele i-substrate yensimbi ekugqwaleni. Emkhathini ojwayelekile, ungqimba lwe-zinc oxide oluncane kakhulu futhi oluminyene lwakhiwa ebusweni bengqimba ye-zinc, okunzima ukuyihlakaza emanzini, ngakho-ke inomphumela othile wokuvikela ku-substrate yensimbi. Uma i-zinc oxide nezinye izingxenye ezisemkhathini zenza usawoti we-zinc ongancibiliki, umphumela wokuvikela ukugqwala ungcono kakhulu.
(2) Nge-iron-zinc alloy layer, ehlanganiswe nokubumbana, ikhombisa ukumelana nokugqwala okuyingqayizivele emkhathini wesifutho sikasawoti sasolwandle kanye nomkhathi wezimboni;
(3) Ngenxa yokuhlangana okuqinile, i-zinc-iron iyancibilika ngokufanayo, futhi inokumelana okuqinile nokugqokwa;
(4) Ngenxa yokuthi i-zinc ine-ductility enhle, futhi ungqimba lwe-alloy yayo inamathela ngokuqinile esisekelweni sensimbi, izingxenye ezicwilisiwe ezishisayo zingakhiwa ngokubhoboza okubandayo, ukugoqa, ukudweba ngocingo, nokugoba ngaphandle kokulimaza ukumbozwa;
