I-Surley iqoqo leUkwelashwa kwangaphambili kanye nezinqubo ze-electrophoresis Idokodo lokufutha ihhavini uhlelo lokudlulisa ebhentshini lokuhlola ishawa ubuchwepheshe bokuvikela imvelo Izesekeli indawo yokusebenzaisitayela konke esitolo esisodwa.

Ukwelashwa kwangaphambili kanye nenqubo yokugcoba ngogesi Isithombe esifakiwe

Ukwelashwa kwangaphambili kanye nenqubo ye-electrocoating

Incazelo emfushane:

I-Coating pretreatment ukulungiswa kwendawo yokumboza ngaphambi kokugqoka futhi kuyisisekelo sayo yonke inqubo yokumboza.
Izinga le-pretreatment lithinta ngqo yonke ikhwalithi yokugqoka, ngakho-ke kufanele siyinake.


Incazelo Yomkhiqizo

Izinto ezihlukahlukene kanye nemikhiqizo yazo ohlelweni lokucubungula, ukuthutha, ukugcinwa, indawo yayo kulula ukuyikhiqiza noma
unamathisele izinto zangaphandle, njenge-machining burr, isikhumba se-oxide, uwoyela, njll., lokhu kungcola okungaphezulu kuzothinta ukubumbana kwe-coating namandla okubopha nge-matrix.Ukwembeswa kwe-substrate kuqala, inhloso ukukhipha lezi zinto nokwenza ukuguqulwa kwamakhemikhali angaphezulu okufanelekile ukuze kuhlinzekwe izimfuneko ezifanele zokugcotshwa kwe-substrate, ukuze kwandiswe ukunamathela kwefilimu, kwelule impilo yesevisi yefilimu, Nikeze ukudlala okugcwele kwesivikelo. umphumela kanye nomphumela wokuhlobisa we-coating.

Ngakho-ke, fafaza okuqukethwe ngaphambi kokucubungula.Ihlanganisa ikakhulukazi izici ezilandelayo:

Ukukhipha amafutha ngaphambi kokugqoka

Insimbi kanye nezingxenye zayo ekugcinweni nasekuthuthweni ukuze kusetshenziswe ukuvikelwa kwamafutha e-antirust, i-workpiece yensimbi yensimbi ekudwebeni uwoyela kufanele isetshenziswe lapho kucutshungulwa ingcindezi, izingxenye kufanele zithinte i-emulsion lapho machining, ukwelashwa kokushisa kungathintana namafutha okupholisa, lapho izingxenye zivame ukuba namafutha. amabala kanye ne-HanJi yezandla zomqhubi, amafutha ezingxenye kodwa futhi nokungcola okufana njalo nothuli kuxutshwe ndawonye Konke lokhu, zonke izinhlobo zamafutha ezingxenyeni azivimbeli nje ukwakheka kwefilimu ye-phosphating, kodwa futhi kuthinta ukunamathela ukomisa ukusebenza kokuhlobisa ukusebenza kokuhlobisa kanye nokumelana nokugqwala Ithebula 3-1 libala ukwelashwa okuhlukile kwepuleti lensimbi eligoqiwe elibandayo.Umthelela we-cathodic electrophoretic coating on corrosion resistance.

I-Phosphating

I-Phosphating iyinqubo elula, enokwethenjelwa, engabizi kakhulu futhi elula yokuthuthukisa kakhulu ukumelana nokugqwala kwe-metal surface coating.Isetshenziswe kabanzi ekhaya nakwamanye amazwe, ikakhulukazi ekugqokeni kwezimoto, okusetshenziswe kabanzi eminyakeni yamuva.Cishe i-100% yezingxenye zamapuleti amancane embonini yezimoto ziyi-phosphating Inqubo ye-Phosphating ibhekisela endaweni yensimbi ehlangene nesisombululo se-asidi esiqukethe usawoti we-dihydrogen phosphate, ukusabela kwamakhemikhali futhi ekhiqizwa ekuzinzeni kwendawo yensimbi yongqimba lwe-membrane ye-inorganic compound engancibiliki. indlela yokwelapha yamakhemikhali engaphezulu kanye nefilimu ekhiqiziwe ebizwa ngokuthi ifilimu ye-phosphating.

Isimiso sefilimu ye-Phosphate

ifilimu ye-phosphating ikwazile ukuhlinzeka ngesisekelo esifanele kakhulu sokumbozwa ngopende, kungenxa yomphumela olandelayo:
1) Inikeza indawo ehlanzekile, efanayo, engenawo amafutha ngesisekelo sokususa amafutha ngokuphelele
I-2) ithuthukisa ukunamathela kwefilimu ephilayo ku-substrate ngenxa yesenzo somzimba kanye namakhemikhali Akunzima ukuqonda ukuthi isakhiwo esinezimbotshana zefilimu ye-phosphating sandisa indawo engaphezulu ye-substrate, ukuze indawo yokuxhuma phakathi kokubili ikhule ngokufanayo, futhi i-permeability enenzuzo phakathi kwezendlalelo ezimbili zefilimu iyakhiqizwa.Ngasikhathi sinye, ukusebenzisana kwamakhemikhali phakathi kwe-resin engagcwele kanye nekristalu ye-phosphate nakho kuthuthukisa amandla ayo okubopha.
I-3) inikeze ungqimba oluzinzile lwe-non-conductive isolation, kanye nomonakalo we-coating, inendima yokuvimbela ukugqwala, ikakhulukazi i-anode incision Iphuzu lokuqala livame ukunganakwa Kuphela kuze kube yilapho uwoyela uphelele ngokuphelele ukuze wenze ifilimu ye-phosphating eyanelisayo. ifilimu ye-phosphating ngokwayo ingumphumela onembile kakhulu wobuchwepheshe bokwelashwa othembeke kakhulu ukuzihlola.
