1. Ukwelashwa Kwangaphambi Kokwelashwa: Ukuze kususwe uwoyela ongadingekile, izinsalela zokushisela, kanye nokungcola ebusweni bokufakwa komzimba wemoto efektri yomzimba, ifilimu ye-zinc phosphate (3~5)㎛) isetshenziswa ebusweni bomzimba ukwandisa ukunamathela ngesikhathi senqubo yokufakwa ngaphansi kwesembozo (i-electrodeposition). Ngenhloso yokuvikela ukugqwala komzimba wemoto.
- Ukuhlanza kwangaphambili: Ngemva kokuhlanganisa umzimba, ugezwa ngamanzi ngaphambi kokususa amafutha.
- Ukususa amafutha emzimbeni wemoto: Kususa uwoyela emzimbeni wemoto.
- Ukuhlanza okunemibandela: I-ejenti yokwelapha ene-titanium njengengxenye eyinhloko, edala inani elikhulu lama-colloid ebusweni bensimbi ukwandisa ukusabela kokwenza ifilimu ye-zinc phosphate ende ukuze kukhiqizwe amakristalu amancane naqinile.
- Ifilimu ye-zinc phosphate: Ifilimu ye-zinc phosphate isetshenziswa ukuqinisa ukunamathela kwe-undercoat nokuvimbela ukusabela kokugqwala.
1) Ukuqopha kuqala engxenyeni ye-anode yeshidi lensimbi esixazululweni sokumboza
2) Kuye ngokuthi i-corrosion current ingakanani, ama-cation asetshenziswa ku-cathode, futhi i-pH ye-interface iyakhuphuka.
3) I-Colloid ebusweni iba yi-nucleus bese iqina
- Ihhavini elomile ngamanzi: Inqubo yokususa umswakama ngokuphelele ku-substrate ngemva kokuba inqubo yokwelapha isiqediwe.
※ Ukudlulisa ukushisa nokomisa ngokusula ngesandla
Ngemva kokumboza umzimba ngefilimu ye-zinc phosphate ( ), yigeze ngamanzi bese uyomisa ngesandla. Ukomisa ngesandla kuyinqubo yokususa ngokuphelele umswakama entweni ezogqokwa bese wenza inqubo elandelayo yokupenda. Phakamisa izinga lokushisa ukuze ukhiphe umswakama ngokudlulisa ukushisa. Ukomisa (ukuhwamuka) kuyinto eyenzeka lapho izinga lokushisa lobuso obuqinile obuthintana nalo liphansi kunephuzu lokubila kanti ingcindezi yomoya iphansi kunengcindezi yomhwamuko. Kuzoshintsha isigaba. Izinga lokushisa nesikhathi esidingekayo sesithando sokomisa esigqokwa ngesandla kuyahlukahluka kuye ngezinto, ubukhulu, kanye nesimo sento ezogqokwa. Ngokuvamile, imizuzu eyi-10 ku-120~150℃ ivamile, futhi isizathu sokuphakamisa izinga lokushisa ukwandisa ingcindezi yomhwamuko wamanzi ehambisana nalelo zinga lokushisa nokomisa ngokushesha ngokunikeza amandla okushisa engeziwe. Ngalesi sikhathi, akufanele kube khona ushintsho lwensimbi noma lwamakhemikhali ngenxa yezinga lokushisa.
1,Inqubo yokubeka i-electrode: Inqubo yokwenza ifilimu yokumboza ngaphakathi/ngaphandle komzimba wemoto ngokusebenzisa i-electrophoresis ngogesi ngemva kokucwilisa umzimba wemoto ngopende wokuma kwe-electrode, ngenhloso yokuvimbela ukugqwala komzimba wemoto.
- Ukufakwa kwe-Electrode: Ukupenda kwe-Electrodede kuyinqubo yokupenda lapho upende uhlanganiswa ngogesi ngokucwilisa umzimba wemoto esixazululweni sopende bese kugeleza i-anode noma i-cathode emzimbeni wemoto. Kodwa-ke, kuyindlela efanele ukukhiqizwa ngobuningi, futhi kunzima ukuyipenda kabusha uma ifilimu yokumboza isinamathiselwe futhi ugesi ungahambi.
- Hlanza nge-DI
- Isithando Sokomisa Se-Electrode: Ukuze kufakwe i-cationic electrodeposition, ezisetshenziswa kakhulu, kusetshenziswa isithando sokomisa ukushisa ngoba ifilimu ebekwe phezu kobuso ilungiswa ngokushisa ngokusabela kokushisa (ukushisa). Izinga lokushisa nesikhathi esidingekayo sokushisa kuyahlukahluka kuye ngezinto, ubukhulu, kanye nesimo sento ezogqokwa. Endabeni yento ezogqokwa encane, izinga lokushisa lobuso lingu-200-210°C kanti izinga lokushisa lokushisa lingu-210-230°C, kanti isikhathi sokushisa ngokuvamile singu-20-30 imizuzu iyonke imizuzu eyi-10 noma ngaphezulu ukuze kufakwe isikhathi sokushisa sento ezogqokwa kanye nesikhathi sokubamba esingu-200-210°C.
- Ukupholisha kwe-Electrodeposition: Gaya izingxenye ezimahhadlahhadla neziphumayo zobuso ukuze kube bushelelezi.
2, Upende Ophakathi: Lena inqubo yokufaka upende, evame ukubizwa ngokuthi i-primer. Ihlanza indawo ukuze ungqimba oluphezulu lunamathele kahle futhi idlala indima ekuthuthukiseni ukumelana nokugqwala. Ngisebenzisa umbala ohlukile kancane phakathi nendawo ukuze ngifane nombala wengqimba ephezulu.
- Inqubo ephakathi nendawo
- Isithando sokomisa esimaphakathi
3, ijazi eliphezulu: Inqubo yokufaka umbala wemoto obonakalayo kanye nokuqedela ngopende obonakalayo. Muva nje, ngenxa yemithethonqubo yezemvelo, njll., upende oluvikela imvelo (okuqukethwe kwezinto eziguquguqukayo eziphansi) lusetshenziswa kancane kancane. Sula ngemuva kopende ophezulu
- inqubo yejazi eliphezulu
- Isithando sokomisa ijazi eliphezulu
※ Ukudluliselwa kokushisa endaweni ye-electrode/phakathi nendawo/phezulu kokushisa nokomisa isithando somlilo
Esithandweni sokomisa, ukushisa kudluliselwa endaweni ependiwe ngezindlela ezimbili.
Ukuguqulwa komoya: Ukuze kufinyelelwe kalula izinga lokushisa lokushisa kwefilimu yokumboza, kudingeka ukugeleza komoya okusheshayo, futhi ukuguquguquka komoya okusheshayo kutholakala ngokujikeleza umoya oshisayo esithandweni sokomisa ngesivinini somoya omkhulu (ukuguqulwa komoya okuphoqelelwe).
Ukushisa Okukhanyayo: Udonga lushiswa ngama-degree angamakhulu amaningana ngaphezu kwezinga lokushisa lokupholisa lefilimu yokumboza esithandweni sokomisa esenziwe ngokukhethekile, futhi ukushisa okushisayo kudluliselwa endaweni ependiwe ngendlela efanayo nesitofu esifudumeza ngayo umzimba.
