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 ye-electrocoating

Ukwelashwa kwangaphambili kanye nenqubo yokugcoba ngogesi Isithombe esifakiwe

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.

Omaka bomkhiqizo

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. Ukwemboza ukunakekelwa kuqala kwe-mainUmgomo uwukukhipha lezi zinto futhi wenze ukuguqulwa kwamakhemikhali angaphezulu okufanelekile ukuze kuhlinzekwe izimfuneko ezifanele zokumboza i-substrate, ukuze kwandiswe ukunamathela kwefilimu, kwelule impilo yesevisi yefilimu, Kunikeze ukudlala okugcwele emthelela wokuvikela kanye nomphumela wokuhlobisa we-coating.

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

Ukukhipha amafutha ngaphambi kokugqoka

Insimbi kanye nezingxenye zayo kwinqubo yokugcina nokuthutha ukusebenzisa ukuvikela uwoyela we-antirust, i-workpiece yensimbi yeshidi ekudwebeni uwoyela kufanele isetshenziswe lapho kucutshungulwa ingcindezi, izingxenye kufanele zithinte i-emulsion lapho machining, ukwelashwa kokushisa kungathintana namafutha okupholisa, lapho izingxenye zivame ukuba namabala kawoyela kanye ne-HanJi yezandla zomqhubi, amafutha ezingxenye kodwa futhi ukungcola okufana nokuhlala nothuli kuxutshwe ndawonye hhayi kuphela ukwakheka kwamafutha ku-pholisi ifilimu, kodwa futhi ithinta ukunamathela kokusebenza kokumisa okokunamathelayo 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 i-dihydrogen phosphate usawoti, ukusabela kwamakhemikhali futhi ekhiqizwa ekuzinzeni kwendawo yensimbi yongqimba lwe-insoluble inorganic compound yendlela yokwelapha amakhemikhali angaphezulu 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 ye-organic ku-substrate ngenxa yesenzo somzimba kanye namakhemikhali Akunzima ukuqonda ukuthi isakhiwo se-porous sefilimu ye-phosphating sandisa indawo engaphezulu ye-substrate, ukuze indawo yokuxhumana phakathi kokubili ikhule ngokuhambisanayo, futhi ukuvuthwa okuzuzisayo okuzuzisayo phakathi kwezingqimba ezimbili zefilimu kukhiqizwa. 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 wokumboza, unendima yokuvimbela ukugqwala, ikakhulukazi ukusika i-anode Iphuzu lokuqala livame ukunganakwa Kuphela kuze kube yilapho uwoyela ungcono kakhulu ukwenza ifilimu ye-phosphating eyanelisayo
