1. Kwitegura: Kugirango ukureho amavuta adakenewe, ibisigazwa byo gusudira, hamwe n’umwanda hejuru yumubiri wibinyabiziga byinjira mu ruganda rwumubiri, firime ya fosifike ya zinc (3 ~ 5㎛) ikoreshwa hejuru yumubiri kugirango yongere gufatira mugihe cyo gutwika (electrodeposition). inzira. Mu ntumbero yo gukingira umubiri imodoka.
- Mbere yo gukora isuku: Nyuma yo guteranya umubiri, yogejwe namazi mbere yo kwangirika kwinshi.
- Kwangirika kwingenzi: Kuraho amavuta mumubiri wimodoka.
- Koza ibintu bisabwa: Umuti uvura titanium nkigice cyingenzi, ukarema umubare munini wa colloide hejuru yicyuma kugirango wongere imbaraga zo gukora firime ya zinc fosifate yuzuye kugirango ikore kristu nziza kandi yuzuye.
- Filime ya Zinc fosifate: Filime ya zinc fosifate ikoreshwa kugirango ishimangire kwambikwa ikoti munsi no kubuza kwangirika.
1) Gutera bitangirira kuri anode igice cyurupapuro rwicyuma
2) Ukurikije ruswa yangirika, cations ziribwa kuri cathode, hanyuma pH yimbere irazamuka.
3) Colloid hejuru iba nucleus hanyuma ikabora
- Amazi yumye yumye: Igikorwa cyo kuvanaho burundu ubuhehere muri substrate nyuma yuburyo bwo kuvura burangiye.
Transfer Kwimura no gukama mukuma intoki
Nyuma yo gupfuka umubiri na firime ya zinc fosifate (), kwoza amazi hanyuma uyumishe intoki. Kuma intoki zumye ni inzira yo gukuraho burundu ubushuhe mubintu bigomba gutwikirwa hanyuma bigakora inzira ikurikira. Kuzamura ubushyuhe kugirango uhumeke neza binyuze mu guhererekanya ubushyuhe. Kuma (evaporation) nikintu kibaho mugihe ubushyuhe bwubuso bukomeye buhuye buri munsi yubushyuhe kandi umuvuduko wikirere uri munsi yumuvuduko wumwuka. icyiciro cyo guhinduka kizabaho. Ubushuhe nigihe gikenewe kugirango itanura ryumye ryacishijwe intoki riratandukanye bitewe nibintu, ubunini, nuburyo imiterere yikintu igomba gutwikirwa. Mubisanzwe, iminota 10 kuri 120 ~ 150 ℃ irasanzwe, kandi impamvu yo kuzamura ubushyuhe nukwongera umuvuduko wumwuka wamazi uhuye nubushyuhe no gukama vuba mugutanga ingufu nyinshi zubushyuhe. Muri iki gihe, ntihakagombye kubaho ibyuma cyangwa imiti bitewe nubushyuhe.
1 、Inzira ya Electrodeposition: Inzira yo gukora firime itwikiriye imbere / hanze yumubiri wikinyabiziga ukoresheje amashanyarazi ukoresheje amashanyarazi nyuma yo kwibiza umubiri wikinyabiziga irangi rya electrodeposition, hagamijwe gukumira kwangirika kwumubiri wikinyabiziga
- Electrodeposition: Irangi rya Electrodeposition nigikorwa cyo gusiga irangi aho irangi rifatanwa namashanyarazi no kwibiza umubiri wimodoka mumuti wamabara hanyuma ugatemba anode cyangwa cathode mumubiri wimodoka. Nyamara, ni uburyo bukwiranye n’umusaruro mwinshi, kandi biragoye gusiga irangi iyo firime yometseho kandi amashanyarazi ntatemba.
- DI koga
- Itanura rya Electrodeposition: Kumashanyarazi ya cationic electrodeposition, ikoreshwa cyane cyane, itanura ryumisha ryumuriro kuko firime yabitswe hejuru hejuru yoroherezwa nubushuhe bwumuriro hamwe nubushuhe bwumuriro (gukiza ubushyuhe). Ubushyuhe nigihe gikenewe kugirango ubushyuhe bukire buratandukanye bitewe nibikoresho, ubunini, nuburyo imiterere yikintu igomba gutwikirwa. Kubireba ikintu gisa neza cyane, ubushyuhe bwubuso ni 200-210 ° C naho ubushyuhe bwitanura bukiza ni 210-230 ° C, naho igihe cyo gushyushya ni iminota 20-30 yose hamwe muminota 10 cyangwa irenga kuri igihe cyo gushyushya ikintu kigomba gutwikirwa na 200-210 ° C gufata umwanya.
- Electrodeposition polishing: Gusya ibice bigoye kandi bisohoka hejuru yubuso kugirango bikorwe neza.
2 、 Igice cya kabiri: Ubu ni inzira yo gukoresha irangi, bakunze kwita primer. Isukura hejuru kugirango ikote ryo hejuru ifatanye neza kandi igire uruhare mukuzamura ruswa. Nkoresha ibara ritandukanye gato hagati kugirango mpuze ibara ryikoti ryo hejuru.
- Inzira yo hagati
- Itanura ryumye
3 coat ikoti ryo hejuru: Inzira yo gukoresha ibara ryibinyabiziga bigaragara no kurangiza ukoresheje irangi risobanutse. Vuba aha, kubera amabwiriza y’ibidukikije, nibindi, amarangi yangiza ibidukikije (ibintu birimo ibintu bihindagurika) bikoreshwa buhoro buhoro. Kuraho nyuma yumwenda wo hejuru
- inzira yo hejuru
- Itanura ryumye
Transfer Gushyushya ubushyuhe muri electrodeposition / hagati / hejuru hejuru yo gushyushya no gutwika itanura
Mu itanura ryumye, ubushyuhe bwimurirwa hejuru irangi muburyo bubiri.
Convection: Kugirango bigere byoroshye ubushyuhe bwo gukiza ubushyuhe bwa firime ya coating, birasabwa umuvuduko mwinshi, kandi umuvuduko mwinshi uboneka mukuzenguruka umwuka ushyushye mumatara yumye kumuvuduko mwinshi (convection ku gahato).
Ubushyuhe bukabije: Urukuta rushyutswe kugeza kuri dogere magana hejuru yubushyuhe bwo gukiza bwa firime yo gutwika mu itanura ryumye ryabugenewe, kandi ubushyuhe bushyushye bwoherezwa hejuru y’irangi nkuko amashyiga ashyushya umubiri.
