Umehluko phakathi kwekhoyili yamagalvanized coil negalvalumed
Isendlalelo sezinto ze-zinc sisatshalaliswa ngokulinganayo ebusweni beshidi likathayela, elisebenza njengesivikelo se-anodic sensimbi eyisisekelo, okusho ukuthi, ukugqwala okuhlukile kwe-zinc material kuvikela ukusetshenziswa kwesisekelo sensimbi.Lapha, i-zinc ifana nokubalulekile Izihlangu zenyama ezizungeze abalingiswa kufanele zinikelwe ngaphambi kokuba izinhlamvu ezimaphakathi ziphenduke.

1. Imikhiqizo evamile yokuhlanganisa i-zinc ehlanzekile (GI) Imikhiqizo evamile yamathayela ediphu eshisayo ingahlukaniswa ibe isipantshi esijwayelekile, isipantshi esincane, asinaso isipantshi kanye nemikhiqizo yangaphezulu eshelelayo ngokuya ngesimo sangaphezulu.Ngenxa yokumelana nokugqwala okuhle, ukucutshungulwa kahle nokusebenza kahle kokwakhiwa, izindleko eziphansi zokukhiqiza, nokubukeka okuhle, isetshenziswa kabanzi ekwakheni, ezimotweni, ezintweni zikagesi zasendlini nakwezinye izimboni.Ikakhulukazi kuma-spangle amancane futhi akukho mikhiqizo yokumboza i-spangle, izinhlamvu ezingaphezulu zilungile, ziminyene, zibushelelezi, futhi zinokunamathela okungcono nokumelana nokugqwala, ikakhulukazi ezintweni zikagesi zasendlini, ukuhlanganisa imibala nezinye izimboni.
2. I-Zinc Aluminium Alloy Coated Sheet (GF)
I-Zinc-aluminium alloy coated sheet ibizwa nangokuthi i-low-aluminium galvanized steel sheet, futhi ukunamathela kuqukethe.
5% Al, 95% Zn, kanye nemikhondo yezinto ezingavamile zomhlaba.Izinzuzo eziyinhloko ukuthi i-plasticity kanye nokunamathela kokugqoka kuhle kakhulu, futhi ukumelana nokugqwala ngaphambi nangemva kokuguqulwa akuguquki;ukumelana nokugqwala komkhathi izikhathi ezi-2 kuya kwezi-3 kunamashidi asakazwa ashisayo ashisayo, futhi kukwazi ukunamathelana kahle nokushisela.Phakathi kwawo wonke amashidi anamathani, inokuqina okuhle kakhulu, ukumelana nokugqwala kanye nokubumbeka okuqhathaniswa namashidi anama-electro-galvanized.Lo mkhiqizo usetshenziselwa ikakhulukazi izindawo ezimelana nokugqwala nezimelana nesimo sezulu kanye nama-substrates wento enamathelayo.
I-3.I-Aluminium-zinc alloy coated plate (GL) Isakhiwo sokumboza se-aluminium-zinc alloy coated plate yi-Al-Zn alloy, futhi ukwakheka kokumboza kungu-55% Al, 43.3% Zn, 1.6% Si.Indawo yayo ibushelelezi futhi inokumelana nokugqwala okuhle kakhulu komkhathi, okuphindwe izikhathi ezingu-2-6 kuneshidi elifanayo le-hot-dip galvanized.Inokumelana nezinga lokushisa eliphezulu lokugqwala okufana nepuleti le-aluminiyamu eshisayo, futhi ingasetshenziswa isikhathi eside ngaphandle kokuguquka kombala noma ukubola ezingeni lokushisa eliphezulu lama-degree angu-315.Ukumelana nokugqwala kwamanzi kungcono kuneshidi le-galvanized le-dip elishisayo kanye neshidi le-aluminum eshisayo, futhi ukumelana nokugqwala kwenhlabathi kungcono kunokweshidi le-hot-dip galvanized.Ukubonakala kwayo okushisayo kungaphezu kuka-75%, okuphindwe kabili kuneshidi elijwayelekile lama-galvanized.Inokupenda okuhle nokucutshungulwa, futhi kancane kancane ithatha indawo yeshidi likathayela futhi isetshenziswa kabanzi emhlabeni.
4. Ishidi lika-galvanized eligoqiwe elishisayo - ishidi elifakwe emanzini ashisayo liyishidi elifakwe i-galvanized elikhiqizwe ngokuqondile ngokukhetha nokufaka i-galvanizing ngeshidi eligoqwe elishisayo njenge-substrate.Ibhodi lingasetshenziswa kakhulu ekwakhiweni, ezimotweni, ezinqolobaneni zensimbi, ezimotweni zabagibeli besitimela, amabhodi omgwaqo onguthelawayeka, njll. Njengamanje, ukukhiqizwa kwasekhaya kweshidi likathayela eligoqiwe elishisayo lincane uma kuqhathaniswa, futhi iningi lemigqa yokukhiqiza ebilokhu yenziwe. kuqediwe futhi kufakwe ekukhiqizeni kukhona ishidi likathayela elineshidi eligoqiwe elibandayo njenge-substrate.Uma kuqhathaniswa neshidi likathayela eligoqeke ngokubanda, umehluko ekusebenzeni phakathi kweshidi likathayela eligoqelwe elishisayo neshidi eligoqeke elibandayo alilikhulu kakhulu.Ngenxa yokuthi ishidi likathayela eligoqwe ashisayo lisindisa inqubo yokugoqa okubandayo, izindleko zokukhiqiza ziphansi, futhi linenzuzo esobala yentengo.
