Incazelo emfushane:

Ukwelashwa kwangaphambili kokumboza kuwukulungiswa kwendawo yokumboza ngaphambi kokumboza futhi kuyisisekelo senqubo yonke yokumboza.
Ikhwalithi yokwelashwa kwangaphambi kwesikhathi ithinta ngqo ikhwalithi yokumboza yonke, ngakho-ke kumelwe siyinake.

Amathegi Omkhiqizo

Incazelo Yomkhiqizo

Izinto ezahlukahlukene kanye nemikhiqizo yazo enqubweni yokucubungula, ukuthuthwa, isitoreji, ubuso bayo kulula ukukhiqiza noma
Uma unamathela ezintweni zangaphandle, njenge-machining burr, isikhumba se-oxide, uwoyela, njll., lezi zingcolisi zomphezulu zizothinta ukuqina kwesembozo kanye namandla okubopha nge-matrix. Ukwelashwa kwangaphambili kwesembozo esiyinhlokoInhloso ukususa lezi zinto nokwenza ukuguqulwa kwamakhemikhali ongaphezulu okufanele ukuze kuhlinzekwe izidingo ezifanele zesembozo se-substrate, ukuze kwandiswe ukunamathela kwefilimu, kwandiswe impilo yenkonzo yefilimu, Nikeza ukusebenza okugcwele komphumela wokuvikela kanye nomphumela wokuhlobisa wesembozo.

Ngakho-ke, fafaza okuqukethwe ngaphambi kokukucubungula. Lokhu kuhlanganisa kakhulu izici ezilandelayo:

Ukususa amafutha ngaphambi kokumboza

Insimbi nezingxenye zayo enqubweni yokugcina nokuthuthwa zisebenzisa ukuvikelwa kwamafutha okulwa nokugqwala, ishidi lensimbi kumafutha okudonsa kufanele lisetshenziswe lapho kucutshungulwa ingcindezi, izingxenye kufanele zithinte i-emulsion lapho kucutshungulwa, ukwelashwa kokushisa kungathinta uwoyela opholile, lapho izingxenye zivame ukuba namabala kawoyela kanye ne-HanJi yezandla zomqhubi, amafutha ezingxenye kodwa futhi nokungcola okufana nokuhlala njalo nothuli kuxutshwe ndawonye. Konke lokhu, zonke izinhlobo zamafutha ezingxenyeni azigcini nje ngokuvimbela ukwakheka kwefilimu ye-phosphating, kodwa futhi zithinta ukunamathela kokusebenza kokomisa kwesembozo. Ukusebenza kokuhlobisa kanye nokumelana nokugqwala. Ithebula 3-1 libala ukwelashwa okuhlukile kwepuleti lensimbi eligoqiwe elibandayo. Umphumela wesembozo se-cathodic electrophoretic ekumelana nokugqwala.

I-Phosphating

I-Phosphating iyinqubo elula, ethembekile, engabizi futhi elula yokuthuthukisa kakhulu ukumelana nokugqwala kwesembozo sensimbi. Isetshenziswe kabanzi ekhaya nakwamanye amazwe, ikakhulukazi ekumbozeni izimoto, okusetshenziswa kabanzi eminyakeni yamuva nje. Cishe izingxenye eziyi-100% zepuleti elincane embonini yezimoto zi-phosphating. Inqubo ye-Phosphating ibhekisela ebusweni bensimbi obuthintana nesisombululo se-asidi esiqukethe usawoti we-dihydrogen phosphate, ukusabela kwamakhemikhali futhi okukhiqizwa ekuzinzeni kobuso bensimbi kwengqimba ye-membrane ye-inorganic compound enganyibiliki yendlela yokwelapha amakhemikhali ebusweni kanye nefilimu ekhiqizwe ebizwa ngokuthi i-phosphating film.

Isimiso sefilimu ye-phosphate

Ifilimu ye-phosphating ikwazile ukunikeza isisekelo esifanele kakhulu sokumboza upende, kungenxa yomphumela olandelayo:
1) Ihlinzeka ngobuso obuhlanzekile, obufanayo, obungenawo amafutha ngokusekelwe ekususeni amafutha ngokuphelele
2) kuthuthukisa ukunamathela kwefilimu yezinto eziphilayo ku-substrate ngenxa yesenzo somzimba nesamakhemikhali. Akunzima ukuqonda ukuthi isakhiwo esinezimbobo sefilimu ye-phosphating sandisa indawo engaphezulu kwe-substrate, ukuze indawo yokuxhumana phakathi kwalezi ezimbili ikhule ngokufanele, futhi kukhiqizwe ukuvuleka okuzuzisayo phakathi kwezingqimba ezimbili zefilimu. Ngesikhathi esifanayo, ukusebenzisana kwamakhemikhali phakathi kwe-resin engagcwalisiwe kanye ne-phosphate crystal nakho kuthuthukisa amandla ayo okubopha.
3) ukuhlinzeka ngesendlalelo sokuhlukaniswa esingadingi ugesi esizinzile, uma umonakalo wokugqoka ungenawo, unendima yokuvimbela ukugqwala, ikakhulukazi ekusikeni kwe-anode. Iphuzu lokuqala livame ukunganakwa. Kuphela ukuze kutholakale ngokuphelele uwoyela ukuze kwakhiwe ifilimu ye-phosphating eyanelisayo. Ngakho ifilimu ye-phosphating ngokwayo ingumphumela onembile kakhulu wobuchwepheshe bokwelashwa kwangaphambilini, okuthembekile kakhulu ukuzihlola.
