1.Kungaba isikhathi esingakanani esiphelileikhoyili kagesizigcinwe endaweni yokugcina impahla?Kungani?
A: Kuvunyelwe ukugcinwa izinyanga ezintathu ukugwema i-oxidation ebangelwa ukugcinwa isikhathi eside kakhulu.
2. Kuyini ukubekezelelana kobudeishidi lensimbi?
Impendulo: Ukubekezelela ubude akuvunyelwe ukuthi kube nenani elingalungile, futhi umkhawulo awuvunyelwe ukuba udlule +6mm.
3. Iyini i-Zinc Flower spangle?Yini i-spangle esincane?I-spangle esiyiziro?
Impendulo: I-spangle enkulu yi-spangle evamile.Ngokwenqubo evamile yokukhiqiza, i-spangle enkulu ingakhiqizwa.Ububanzi be-crystal nucleus abukho ngaphansi kuka-0.2mm;ububanzi be-crystal nucleus bungaphansi kuka-0.2mm, okubizwa ngokuthi i-spangle encane.Ibonakala ngokubonakalayo.
4. Uyini umgomo wokuvikelaidiphu elishisayo lifakwe insimbiungqimba?
Impendulo: Ngoba i-zinc ingakha ifilimu enokumelana okuhle nokugqwala endaweni egqwalayo.Ayivikeli kuphela isendlalelo se-zinc ngokwayo, kodwa futhi nesisekelo sensimbi.
5. Uyini umgomo wokudluliswa kwekhoyili kagesi ediphu esishisayo?
Impendulo: Ukwelashwa kwe-chromate passivation yeishidi likathayelaingakha ifilimu ye-passivation, futhi ifomula yayo yokusabela kwamakhemikhali imi kanje: Zn+H2GrO4-ZnGrO2=H2
I-chromium e-trivalent emndenini we-passivation we-solution ayincibiliki emanzini, ayisebenzi ngamakhemikhali, futhi isebenza njengohlaka lwamathambo, kuyilapho i-chromium eyi-hexavalent incibilika kalula emanzini futhi ingabamba iqhaza ekudluliselweni kabusha lapho ifilimu ye-passivation iklwejwa.Inomphumela wokuphulukisa wefilimu ye-passivation.Ngakho-ke, ngaphakathi komkhawulo othile, ifilimu ye-passivation ingavimbela ukuguguleka okuqondile kweshidi le-galvanized nge-steam noma umoya omswakama, futhi ungqimba lwe-zinc ludlala indima yokuzivikela.
6. Yiziphi izindlela zokuhlola ukumelana nokugqwala kweIkhoyili yeshidi elinothayela elishisayo?
Impendulo: Kunezindlela ezintathu zokuhlola ukumelana nokugqwala kweshidi elishisayo lokucwilisa: ukuhlolwa kwesifutho sikasawoti;ukuhlolwa komswakama;ukuhlolwa kokuguguleka.
7. Kungani kufanele kwenziwe ukwelashwa okunqanda ukugqwala emikhiqizweni yamantila ediphu elishisayo?
Impendulo: Uma i-hot-dip galvanized sheet isemoyeni oswakeme, ikakhulukazi lapho umoya uqukethe izinto ezine-acidic ezifana ne-SiO2, CO2, NO2 kanye no-CHA, ingaphezulu longqimba olufakwe uthayela maduze lizokwenza ukugqwala okumhlophe okuxekethile.Izingxenye eziyinhloko zokugqwala okumhlophe yi-ZnO ne-Zn(OH) 2. Lolu hlobo lokugqwala okumhlophe aluthinti nje ukubonakala, kodwa futhi luletha ubunzima obukhulu ekusebenziseni esikhathini esizayo.
8. Yiziphi izimbangela zokugqwala okumhlopheikhoyili kagesi?
Impendulo: Izizathu zokugqwala okumhlophe yilezi: i-hot-dip galvanizing ifakwa kanye nezinye izinto ezigqwalayo ezifana ne-asidi, i-alkali nosawoti;ifilimu ye-passivation noma i-anti-ifilimu yonakalisiwe;i-passivation noma i-oiling effect ayilungile;indawo yokugcina impahla ayinawo umoya omuhle, Umswakama;ishidi likathayela lifafazwa ngamanzi ngesikhathi sokuthutha;ithuthwa ekushiseni okuphansi futhi igcinwe ekushiseni okuphezulu, yakha i-condensation.
