Umugqa wokukhiqiza we-Automobile cab electrophoresis
Umdwebo we-Electrophoretic ngokuvamile uhilela izinqubo ezine ngesikhathi esisodwa
1. I-Electrophoresis: ngaphansi kwesenzo sensimu kagesi yamanje eqondile, izinhlayiya ze-colloidal ezikhokhiswayo ezinhle nezimbi ukuya ku-negative, ukunyakaza okuqondile, okubizwa nangokuthi ukubhukuda.
2. I-Electrolysis: ukusabela kokunciphisa i-oxidation kwenziwa ku-electrode, kodwa ukwenzeka kwe-oxidation nokunciphisa kwakhiwa ku-electrode.
3.I-Electrodeposition: ngenxa ye-electrophoresis, izinhlayiya ze-colloidal ezikhokhisiwe zithuthele ku-anode eduze kwendawo yesifanekiso ekhishwe ama-electron, kanye ne-insoluble deposition, ukwenzeka kwemvula, ngalesi sikhathi ifilimu kapende kwakheka.
4. I-Electroosmosis: Ngaphansi kwesenzo senkundla kagesi, isigaba esiqinile asinyakazi, kodwa isigaba se-liquid sinyakaza into ethile.I-Electroosmosis ibangela ukuthi amanzi efilimu kapende akhishwe kancane kancane aye ngaphandle kwefilimu, futhi ekugcineni yakhe ifilimu kapende elicinene elinamanzi aphansi kakhulu kanye nokumelana okuphezulu, okungakwazi ukudlula kumanje.
5. Upende obomvu we-iron oxide epoxy electrophoretic, isibonelo: upende we-electrophoretic i-epoxy resin eguquliwe, i-butanol ne-ethanol amine, i-talcum powder, ukwakheka kwezinto ezibonakalayo ze-iron oxide, upende we-electrophoresis uxutshwa namanzi acwecwe, ngaphansi komphumela wensimu ye-dc, ehlukanisiwe. ibe yi-cationic ne-anionic ene-positively charged, eshajwa kabi kanye nochungechunge lwekhemikhali ye-colloidal eyinkimbinkimbi, inqubo ye-electrochemical chemistry.
Izindlela zokugqoka ze-Electrophoretic namakhono
1. I-electrophoretic coating yendawo yensimbi evamile, inqubo yayo ithi: ukuhlanza ngaphambili → ku-inthanethi → ukugcoba → ukugeza → ukususwa kokugqwala → ukugeza → ukungathathi hlangothi → ukugeza → phosphating → ukugeza → passivation → ukuhlanza kwe-electrophoretic → ukuhlanza ethangini → ukugeza okuhlunga kakhulu → ukumisa → okungaxhunyiwe ku-inthanethi.
2. I-substrate ne-pretreatment ye-coating inethonya elikhulu kwifilimu yokugqoka i-electrophoretic.Ama-castings ngokuvamile asebenzisa i-sandblasting noma ukuqhuma kwesibhamu ukuze kususwe ukugqwala, ngentambo kakotini ukuze kususwe uthuli oluntantayo endaweni yokusebenza, ngephepha lesanti elingu-80# ~ 120# ukuze kukhishwe isibhamu sensimbi esalayo nezinye izinto ngaphezulu.Ingaphezulu lensimbi liphathwa ngokususa amafutha kanye nokususwa kokugqwala.Lapho izidingo ezingaphezulu ziphezulu kakhulu, ukwelashwa kwe-phosphating kanye ne-passivation surface kungenziwa.Insimbi engagqwali kufanele ibe yiphosphating ngaphambi kwe-anodic electrophoresis, ngaphandle kwalokho ukumelana nokugqwala kwefilimu kapende kubi.Ukwelashwa kwe-Phosphating, ngokuvamile kukhetha ifilimu ye-zinc kasawoti phosphating, ukushuba okungaba ngu-1 ~ 2μm, kudinga i-crystallization enhle neyunifomu yefilimu ye-phosphating.
3. Kuhlelo lokuhlunga, ukusetshenziswa okuvamile kwesihlungi, isihlungi sesakhiwo sesikhwama semesh, indawo yokuvula engu-25 ~ 75μm.Upende we-Electrophoretic uhlungwa ngepompo eqondile ukuya kusihlungi.Uma kucatshangelwa izici ezifana nesikhathi sokushintsha kanye nekhwalithi yefilimu, isikhwama sokuhlunga esinembobo esingu-50μm singcono kakhulu.Ayikwazi ukuhlangabezana nezidingo zekhwalithi zefilimu kuphela, kodwa futhi ixazulule inkinga yokuvinjelwa kwesikhwama sokuhlunga.
4. Inani lokuzungeza lesistimu yokuhlanganisa i-electrophoretic lithinta ngokuqondile ukuzinza koketshezi lokugeza kanye nekhwalithi yefilimu kapende.Ngokukhula kokujikeleza, imvula nebhamuza ethangini kuncipha.Kodwa-ke, ukuguga kwethangi kuyashesha, ukusetshenziswa kwamandla kuyanda, futhi ukuzinza kwethangi kuba kubi kakhulu.Kuhle ukulawula inombolo yomjikelezo we-tank liquid 6 ~ 8 izikhathi / h, hhayi kuphela ukuqinisekisa ikhwalithi yefilimu kapende, kodwa futhi nokuqinisekisa ukusebenza okuzinzile kwe-tank liquid.
5.Ngokunwetshwa kwesikhathi sokukhiqiza, i-impedance ye-anode diaphragm izokhula, futhi amandla okusebenza asebenzayo azokwehla.Ngakho-ke, ngokusho kokulahlekelwa kwe-voltage ekukhiqizeni, i-voltage yokusebenza kwamandla kagesi kufanele ikhuliswe kancane kancane ukuze kunxeshezelwe ukwehla kwe-voltage ye-anode diaphragm.
6.Uhlelo lwe-Ultrafiltration lulawula ukugcwala kwama-ion angcolile alethwe endaweni yokusebenza ukuze kuqinisekiswe ikhwalithi yokumboza.Ekusebenzeni kwalesi simiso, ukunakwa kufanele kukhokhwe ekusebenzeni okuqhubekayo kwesistimu ngemva kokusebenza, ukusebenza okungapheli kuvinjelwe ngokuqinile ukuvimbela ukomiswa kwe-membrane ye-ultrafiltration.I-resin eyomile kanye ne-pigment inamathela kulwelwesi lwe-ultrafiltration futhi ayikwazi ukuhlanzwa kahle, okuzothinta kakhulu ukufinyeleleka kanye nempilo yesevisi ye-membrane ye-ultrafiltration.Izinga lokuchitheka kolwelwesi lwe-ultrafiltration liyancipha ngesikhathi sokusebenza, futhi kufanele lihlanzwe kanye izinsuku ezingama-30 kuya kwezingama-40 ukuze kuqinisekiswe ukuthi amanzi acwebileyo adingekayo ekuvuzeni nasekuwasheni.
7. Indlela yokugqoka i-Electrophoretic ifanele inombolo enkulu yemigqa yokukhiqiza.Umjikelezo wokushintsha ithangi le-electrophoresis kufanele ube ngaphansi kwezinyanga ezi-3.Ukuthatha umugqa wokukhiqiza we-electrophoresis onomphumela wonyaka wezindandatho zensimbi ezingu-300,000 njengesibonelo, kubaluleke kakhulu ukuphatha ngokwesayensi uketshezi lwethangi.Imingcele ehlukahlukene ye-tank liquid ihlolwa njalo, futhi uketshezi lwethangi luyalungiswa bese lushintshwa ngokuya ngemiphumela yokuhlolwa.Ngokuvamile, imingcele ye-tank liquid ikalwa ku-frequency elandelayo: inani le-PH, okuqukethwe okuqinile kanye ne-conductivity yesisombululo se-electrophoresis, isisombululo sokuhlanza i-ultrafiltration ne-ultrafiltration, i-cathode (anode) liquid, isixazululo sokugeza okujikelezayo kanye nesisombululo sokuhlanza i-deionized kanye ngosuku;Isilinganiso sesisekelo sobuso, okuqukethwe kwe-organic solvent, ukuhlolwa kwethangi elincane laselabhorethri kabili ngeviki.
8. Ikhwalithi yokuphathwa kwefilimu kapende, kufanele ihlole ukufana nokushuba kwefilimu, ukubukeka akufanele kube ne-pinhole, ukugeleza, ikhasi lewolintshi, imibimbi kanye nezinye izenzakalo, hlola njalo ukunamathela kwefilimu, ukumelana nokugqwala nokunye okungokomzimba nokunye. izinkomba zamakhemikhali.Umjikelezo wokuhlola ngokuya ngezindinganiso zokuhlola zomkhiqizi, ngokuvamile indawo ngayinye kufanele ihlolwe.
Ukusetshenziswa kwe-electrophoretic coating kanye nopende ophuma emanzini kuphawula inqubekelaphambili enkulu embonini yokuhlanganisa.
Electrophoretic enamathela ukwakhiwa isivinini, imishini kanye ezishintshayo kungabonakala, ukusebenza okuqhubekayo, ukunciphisa amandla abasebenzi, iyunifomu ngopende ifilimu, adhesion eqinile, ngoba indlela jikelele enamathela akulula ukuba camera noma izingxenye camera kabi, ezifana izimbambo ezishiwo ngenhla, amashisela. nezinye izindawo zingathola ifilimu kapende elibushelelezi.Izinga lokusebenzisa upende lifika ku-90% -95%, ngoba upende we-electrophoretic ngu-wi-ater njenge-solvent, engashi, engenabuthi, kulula ukuyisebenzisa kanye nezinye izinzuzo.Ifilimu yepende yokomisa i-Electrophoretic, enamathela kahle kakhulu, ukumelana nokugqwala kwayo, ukumelana nokugqwala, ukumelana nesimo sezulu nezinye izakhiwo zingcono kunopende ojwayelekile kanye nendlela yokwakha ejwayelekile.
Isetshenziselwa zonke izinhlobo zomdwebo we-workpiece, amanye amamodeli angenziwa ngokwezifiso.

Uhlobo lwe-spray yokukhiqiza umugqa wokukhiqiza ngaphambi kokwelashwa
Ukwelashwa kwangaphambili kokumboza kuhlanganisa ukwehlisa (ukwehlisa), ukususwa kokugqwala, ukwenza izingxenye ezintathu ze-phosphating.I-Phosphating iyisixhumanisi esiyinhloko, ukukhishwa kwe-degreasing kanye nokugqwala kuyinqubo yokulungiselela ngaphambi kwe-phosphating, ngakho-ke ekusebenzeni kokukhiqiza, akufanele nje sithathe umsebenzi we-phosphating njengokugxila, kodwa futhi siqale kusukela kuzidingo zekhwalithi ye-phosphating, senze umsebenzi omuhle ngaphezu kwalokho. uwoyela nokugqwala ukususwa, ikakhulukazi naka ithonya mutual phakathi kwabo....
