Umehluko Phakathi Kwe-Hot-Dip Galvanizing kanye Ne-Mechanical Galvanizing

I-hot dip galvanizing iyinqubo yokwelapha engaphezulu ebandakanya ukucwiliswa kwezingxenye ezilashwe ngaphambili kubhavu we-zinc ukuze kutholakale ukusabela kwensimbi okunezinga lokushisa eliphezulu ukuze kwakhe ukunamathela kwe-zinc Izinyathelo ezintathu zokugalela idiphu elishisayo zimi kanje:

① Ingaphezulu lomkhiqizo lincibilika ngoketshezi lwe-zinc, futhi indawo esekwe ku-iron ihlakazwa uketshezi lwe-zinc ukwenza isigaba se-zinc iron alloy.

② Ama-ion e-zinc ongqimba lwengxubevange aphinde asakazekele ngasematrix ukuze akhe ungqimba lwe-zinc iron mutual solution; I-ayoni yakha ingxubevange yensimbi ye-zinc ngesikhathi sokuncibilika kwesisombululo se-zinc futhi iyaqhubeka nokusabalala ibheke endaweni ezungezile Ingaphezulu le-zinc iron alloy layer ligoqwe ngongqimba lwe-zinc, oluphola futhi lucwebezele ekushiseni kwekamelo ukuze kwakheke ukunamathela. Njengamanje, inqubo yokufaka idiphu eshisayo yamabhawodi isiya ngokuya iphelele futhi izinzile, futhi ukushuba kokumboza nokumelana nokugqwala kungahlangabezana ngokugcwele nezidingo zokunqanda ukugqwala kwemishini ehlukahlukene. Nokho, kusenezinkinga ezilandelayo ekukhiqizweni nasekufakweni kwezinsiza zomshini:

1. Kukhona inani elincane lezinsalela ze-zinc kuntambo ye-bolt, ethinta ukufakwa,

2. Umthelela emandleni okuxhumana ngokuvamile ufinyelelwa ngokwandisa isabelo somshini senati kanye nokuhlehla ngemva kokucwecwana ukuze kuqinisekiswe ukulingana phakathi kwamantongomane e-hot-dip galvanized kanye nebhawodi. Nakuba lokhu kuqinisekisa ukulingana kwe-fastener, ukuhlola ukusebenza komshini kuvame ukwenzeka phakathi nenqubo yokushuba, okuthinta amandla okuxhuma ngemva kokufakwa.

3. Umthelela ezicini zemishini zamabhawodi anamandla amakhulu: Inqubo engafanele yokufaka amabhawodi ashisayo ingathinta ukuqina komthelela wamabhawodi, futhi ukugeza i-asidi ngesikhathi senqubo yokufaka uthayela kungakhuphula okuqukethwe kwe-hydrogen ku-matrix yamabhawodi aqinile ebanga le-10.9. , okwandisa amandla okukhishwa kwe-hydrogen. Ucwaningo luye lwabonisa ukuthi izakhiwo zemishini zezingxenye ezinentambo zamabhawodi aqine kakhulu (ibanga lesi-8.8 nangaphezulu) ngemva kokufakwa kwe-galvanizing yediphu eshisayo zinezinga elithile lomonakalo.

I-Mechanical galvanizing iyinqubo esebenzisa ukufakwa ngokomzimba, i-chemical adsorption, kanye nokushayisana kwemishini ukuze kwakhe ukumbozwa kwempushana yensimbi phezu kwendawo yokusebenza ekamelweni lokushisa nokucindezela. Ngokusebenzisa le ndlela, izimbotshana zensimbi ezifana ne-Zn, Al, Cu, Zn-Al, Zn-Ti, ne-Zn-Sn zingakhiwa ezingxenyeni zensimbi, zinikeze ukuvikeleka okuhle kwe-substrate yensimbi yensimbi. Inqubo yokufaka uthayela ewumshini ngokwayo inquma ukuthi ukujiya kwemicu nemisele kuncane kunokwezindawo eziyisicaba. Ngemuva kokucwenga, amantongomane awadingi ukuthepha emuva, futhi amabhawodi angaphezu kwe-M12 awadingi ngisho nokubeka ukubekezelelana. Ngemuva kwe-plating, akuthinti ukufaneleka kanye nezakhiwo zemishini. Kodwa-ke, usayizi wezinhlayiyana ze-zinc powder esetshenziswa kule nqubo, amandla okuphakela ngesikhathi senqubo yokucwenga, kanye nesikhathi sokuphakela kuthinta ngokuqondile ukuminyana, ukucaba, nokubukeka kwento enamathelayo, ngaleyo ndlela kuthinte ikhwalithi yokumboza.
