1.Kungade kube nini ukugqitywaikhoyili yagalvanizedzigcinwe kwindawo yokugcina impahla?Ngoba?
A: Ivumelekile ukuba igcinwe iinyanga ezintathu ukuphepha i-oxidation ebangelwa ukugcinwa ixesha elide.
2. Yintoni ubude bokunyamezelasheet sheet intsimbi?
Impendulo: Ukunyamezela ubude akuvumelekanga ukuba kube nexabiso elibi, kwaye ubuninzi buvunyelwe ukuba budlule + 6mm.
3. Yintoni iZinc Flower spangle?Yintoni ispantshi esincinci?Iziro spangle?
Impendulo: Isipantshi esikhulu sisipantshi esiqhelekileyo.Ngokwenkqubo eqhelekileyo yokuvelisa, i-spangle enkulu inokuveliswa.Ububanzi be-crystal nucleus ayikho ngaphantsi kwe-0.2mm;ububanzi be-crystal nucleus bungaphantsi kwe-0.2mm, ebizwa ngokuba yi-spangle encinci.Ibonakala ngokubonakalayo.
4. Yintoni umgaqo wokukhuselaishushu-dip yenziwe yagalvanizedumaleko?
Impendulo: Ngenxa yokuba i-zinc inokwenza ifilimu enokumelana ne-corrosion efanelekileyo kwindawo engcolileyo.Ayikhuseli kuphela i-zinc layer ngokwayo, kodwa kunye nesiseko sensimbi.
5. Uthini umgaqo wokugqitha kwikhoyili yegalvanized yediphu eshushu?
Impendulo: Unyango lwe-chromate passivation lweishidi elenziwe ngesinyithiinokwenza ifilimu ye-passivation, kunye nefomula yayo yokuphendula imichiza ngolu hlobo lulandelayo: Zn+H2GrO4-ZnGrO2=H2
I-chromium ye-trivalent kwintsapho ye-solution passivation ayinyibiliki emanzini, ikhemikhali ayisebenzi, kwaye isebenza njenge-skeleton, ngelixa i-chromium ene-hexavalent i-soluble kalula emanzini kwaye inokudlala indima ekugqithiseni kwakhona xa ifilimu ye-passivation ikrwelwa.Inefuthe lokuphilisa ifilimu ye-passivation.Ngoko ke, ngaphakathi komda othile, ifilimu ye-passivation inokuthintela ukukhukuliseka ngokuthe ngqo kwephepha le-galvanized nge-steam okanye umoya omanzi, kwaye i-zinc layer idlala indima yokukhusela.
6. Zeziphi iindlela zokuvavanya ukuxhathisa umhlwahot-dip iphepha ikhoyili yagalvanized?
Impendulo: Kukho iindlela ezintathu zokuvavanya ukuxhathisa ukubola kweshiti elishushu-diphu: uvavanyo lwesitshizi setyuwa;uvavanyo lokufuma;uvavanyo lokhukuliseko.
7. Kutheni kufuneka kuqhutywe unyango lokulwa nomhlwa kwiimveliso zegalvanized zediphu eshushu?
Impendulo: Xa i-at-dip galvanized sheet ikumoya omanzi, ngakumbi xa umoya uqulethe izinto ezine-acidic ezifana ne-SiO2, CO2, NO2 kunye ne-NO, umphezulu we-galvanized layer uya kudala umhlwa omhlophe okhululekileyo.Amacandelo aphambili e-rust emhlophe yi-ZnO kunye ne-Zn (OH) 2. Olu hlobo lwe-rust emhlophe aluchaphazeli nje ukubonakala, kodwa luzisa ubunzima obukhulu ekusebenziseni ixesha elizayo.
8. Ziziphi izizathu zomhlwa omhlopheikhoyili yagalvanized?
Impendulo: Izizathu zerusi emhlophe zezi: i-galvanizing eshushu-dip ibekwe kunye nezinye izinto ezinobungozi ezifana ne-asidi, i-alkali kunye netyuwa;ifilimu ye-passivation okanye i-anti-film yonakaliswe;i-passivation okanye i-oiling effect ayilungile;indawo yokugcina impahla ayinamoya kakuhle, Ukufuma;Iphepha elifakwe igalvanized lifafazwe ngamanzi ngexesha lokuthuthwa;ihanjiswe kwiqondo lokushisa eliphantsi kwaye igcinwe kwiqondo lokushisa eliphezulu, yenze i-condensation.
