Izinkinga ezihlukahlukene zivame ukuba khona ku-zinc-aluminiumenamathelainqubo, kanye nendlela yokuthola imbangela yangempela yalobu bunzima isibe iphuzu elinzima embonini yokugqoka.
Ngaphandle kwe-workpiece yomkhiqizo ngokwawo, impahla eluhlaza ebaluleke kakhulu yokugqoka i-zinc-aluminium yisisombululo se-zinc-aluminium micro-coating.Ukulawulwa kabi kwesisombululo se-zinc-aluminium coating kungaholela ezimeni eziningi ezingathandeki, njengokuqoqwa kwesixazululo, ukubukeka okumnyama sekukonke, ukuwohloka kwe-watermark, ukunamathela okubi, nokwehluleka kwesifutho sikasawoti, njll.
Ukuqoqwa kwesixazululo ikakhulukazi ngenxa ye-viscosity ephezulu kakhulu kanye nezinga lokushisa lesisombululo sokumboza kanye nokwehluleka kwe-centrifugal ukunyakazisa ngokuphumelelayo isisombululo sokumboza ngokweqile.
Ukubukeka okumnyama sekukonke kungenxa yokuthi isixazululo sokumboza asinyakaziswa ngokulinganayo futhi okuqukethwe okuqinile kongqimba olungaphezulu lwesixazululo sokumboza kuphansi, ngakho-ke noma ngabe ukumbozwa kukhangisiwe ku-workpiece, ukugqoka kuzolahleka (izithako eziqinile ezisebenzayo zilahlekile. ngokwengxenye yendawo) ngokugeleza kwesisombululo sokumboza ngokwaso ngemva kokungena esiteshini sokumisa.
Ukuwohloka kwe-Watermark ngokuyinhloko kubangelwa ukuxubana okungalingani kanye nombala ongaguquki wesixazululo sokumboza.
Ukunamathelisa kahle kubangelwa ikakhulukazi izinto eziningi ezingavumelekile kusixazululo sokumboza (njengokudubula kwensimbi, inhlaka ene-oxidized, nothuli lwempushana yensimbi).
Kunezizathu eziningi zokuhluleka kwesifutho sikasawoti, futhi noma yiziphi izinguquko ezicashile kusixazululo se-zinc-aluminium coating zizoba nomthelela kuso.Kodwa-ke, isifutho sikasawoti siwukusebenza okubaluleke kakhulu esikudingayo ukuze sifinyelele umgomo.
Ngakho-ke, kubalulekile ukwenza isiqiniseko sokuthi ukugcinwa nokusetshenziswa kwesisombululo sokumboza kuyalawulwa.
Ukugcinwa nokusetshenziswa kwamanothi esisombululo se-zinc-aluminium enamathela enqubweni yokumboza
1. Isilinganiso senkomba yesixazululo sokusebenza sesisombululo sokumboza
Linganisa i-viscosity njalo ngo-2h, likala izinga lokushisa kanye nomswakama njalo ngo-2h, bese ukala okuqukethwe okuqinile kanye ngokushintshashintshayo
2. Ukuxuba isisombululo sokusebenza sikapende
I-mixer enkulu kufanele isetshenziselwe ukuxuba ngokugcwele isixazululo sokumboza esisebenzayo ethangini lokucwilisa imizuzu eyi-15 ngaphambi kokufaka umugqa wokumboza, futhi isixazululo sokumboza esisekelwe ngamafutha emgqeni wokumboza kufanele sikhishwe emugqeni ngemva kwamahora angu-12 omsebenzi oqhubekayo futhi kabusha. -ixutshwe i-10min egumbini lokunikezela ngaphambi kokuthi isetshenziswe ku-inthanethi.
Ngokohlelo lokuhlela ukukhiqiza, isixazululo sokumboza ukuvikela imvelo esisekelwe emanzini kufanele sidonswe sibuyiselwe egumbini lokukhipha impahla elivalwe ngokushisa okungapheli ukuze kuvinjelwe ukuguga kwesisombululo sokumboza uma lungekho uhlelo lokukhiqiza olutholakala okungenani izinsuku ezintathu.
3. Ukuhlunga
Hlunga okusekelwe kuwoyelaenamathelaisixazululo kanye ezinsukwini ezi-3 zokusebenza, isixazululo se-oyela-top coating kanye ezinsukwini zokusebenza ezingu-7, kanye nesisombululo sokumboza esisekelwe emanzini kanye ezinsukwini zokusebenza eziyi-10.Ngenkathi uhlunga, susa isibhamu sensimbi kanye ne-iron powder esixazululweni sokumboza.Imvamisa yokuhlunga kufanele yandiswe esimweni sezulu esishisayo noma uma kunezinkinga zekhwalithi.
4. Ukuvuselela
Ngesikhathi sokusetshenziswa okuvamile kwesisombululo sokumboza ethangini lokucwilisa, isixazululo sokumboza kanye nesincane esixubene egumbini lokukhipha siyanezelwa futhi sivuselelwe.
Ukuhlolwa kwedatha kufanele kuqedwe ngesixazululo sokumboza esingakaze sisetshenziswe okungenani isonto elilodwa ethangini lokucwilisa ngaphambi kokuba sifakwe entanjeni yokumboza futhi, futhi angeke ifakwe emgqeni ngaphandle uma ukuhlolwa kufaneleka.Uma kwenzeka kuchezuka kancane, khipha i-1/4 yesisombululo sokumboza ethangini lokucwilisa, engeza i-1/4 yesixazululo esisha sokuvuselela, futhi ukhiphe ingxenye yesixazululo sokuqala esizokwengezwa ngendlela engu-1:1 lapho uhlanganisa isisombululo esisha sokukhiqiza okulandelayo.
5. Ukuphathwa kwesitoreji
Izinga lokushisa lesitoreji kanye nomswakama (ikakhulukazi ehlobo) kufanele kulawulwe futhi kurekhodwe ngokuhambisana ngokuqinile nemiyalelo, futhi kubikwe ngesikhathi lapho izinga selidlulile.
Ukushisa kwesitoreji sethangi lesisombululo sokugqoka ekamelweni lokukhipha kufanele kube eduze ngangokunokwenzeka ekushiseni kwangaphandle ukuze kugwenywe amaconsi amanzi ngenxa yamazolo okuthinta ukusebenza kwesisombululo.Izinga lokushisa lokugcina lethangi elisha lesixazululo lingama-20±2℃ ngaphambi kokuvulwa.Uma umehluko phakathi kwesisombululo esisha sokumboza nezinga lokushisa langaphandle mkhulu, ithangi lesixazululo kufanele livalwe ngaphandle amahora angu-4 ngaphambi kokwengeza ukuze kuqinisekiswe ukuthi izinga lokushisa ngaphakathi nangaphandle kwethangi liyafana.
6. Izinyathelo zokuphepha zokusetshenziswa
(1) Noma yiliphi ithange lekhambi elingena noma eliphuma egunjini lokukhiphela impahla kufanele livalwe ngefilimu yokugoqa bese limbozwa ngesivalo sethangi.
(2) Thatha izinyathelo zokuzivikela lapho lina futhi liswakeme kakhulu.
(3) Ngesikhathi sokuvalwa kwesikhashana okubangelwa izinkinga ezihlukahlukene zemishini, ithangi lokucwilisa akumele libekwe obala esimweni esingasebenzi isikhathi esingaphezu kwamahora ama-4.
(4) Ukuqinisekisa ukuzinza kwesisombululo sokumboza, azikho izinto ezishisayo (ikakhulukazi ama-workpieces angazange apholile ekamelweni lokushisa) kufanele athintane nesisombululo sokugqoka kuyo yonke imigqa.
