Kuyini ukwelashwa kobuso kwamaphrofayili e-aluminium
2024-08-01
Ukukhiqizwa komnyango we-aluminium alloy kanye Iphrofayela YefasitelaI-s ingahlukaniswa ngezinqubo ezine: ukulungiswa kwe-ingot, ukubumba i-extrusion, ukwelashwa kokushisa, kanye nokwelashwa kwendawo. Ngokuthuthuka okuqhubekayo kwezindinganiso zokuphila zabantu, izidingo zokubukeka nombala weminyango namafasitela ziphakeme kakhulu. Futhi ngokuthuthukiswa kancane kancane kobuchwepheshe bokucubungula i-aluminium, ezinye izindlela zokwelapha indawo eziyinkimbinkimbi ziye zathuthukiswa ngamandla. Sivame ukubona izinqubo zokwelapha indawo ye-aluminium njenge-electrophoresis, i-anodic oxidation, kanye nokufutha ngopende we-fluorocarbon, njll.
1. I-Electrophoresis
I-Electrophoresis inqubo lapho upende we-electrophoretic ubekwa khona ebusweni bento yokusebenza ku-cathode kanye ne-anode. Ngaphansi kwesenzo se-voltage, ama-ion opende ashajiwe aya ku-cathode futhi akhe into enganyibiliki ngesenzo se-alkaline esakhiwe ebusweni be-cathode. Iphrofayili ye-aluminium i-electrophoresis ibhekisela enkambisweni yokubeka i- I-Alu enwetshiwei-alloy encane ethangini le-electrophoresis bese kwakheka ifilimu ye-resin ejiyile ngaphandle ngemva kokusetshenziswa kogesi oqondile. Amaphrofayili e-aluminium e-electrophoretic akhanya kakhulu futhi anomphumela wesibuko, okuthuthukisa nokumelana nokugqwala.
Ukugeleza Kwenqubo: I-Electrolysis (Ukubola) ➤ I-Electrophoresis (Ukubhukuda, Ukufuduka) ➤ I-Electrodeposition (Ukuna kwemvula) ➤ I-Electroosmosis (Ukuphelelwa amanzi emzimbeni)
2. Ukushiswa kwe-Anodic
Ukushiswa kwe-anodic kwamaphrofayili e-aluminium kubhekisela enkambisweni yokwakha ungqimba lwefilimu ye-oxide emikhiqizweni ye-aluminium (i-anode) ngenxa yesenzo samandla kagesi asetshenziswayo ngaphansi kwe-electrolyte ehambisanayo kanye nezimo zobuchwepheshe ezithile ze-aluminium kanye nama-alloy ayo. Kodwa-ke, ifilimu ye-oxide eyakhiwe ngaphandle kwe-aluminium eshisiwe ihlukile kwifilimu ejwayelekile ye-oxide, futhi i-aluminium eshisiwe ingadaywa ngombala we-electrolytic. Ukuze kunqotshwe amaphutha ebulukhunini kanye nokumelana nokuguguleka kokubukeka kwe-aluminium alloy, kwandiswe ububanzi bokusetshenziswa futhi kwandiswe impilo yesevisi, ubuchwepheshe bokwelashwa kwendawo bube yisixhumanisi esibalulekile ekusetshenzisweni kwe-aluminium alloy, kanti ubuchwepheshe be-anodic oxidation buyindlela esetshenziswa kakhulu futhi ephumelelayo njengamanje.
Ukugeleza kwenqubo
Ukususa amafutha ➤ Ukupholisha kwamakhemikhali ➤ Ukugqwala kwe-asidi ➤ Ukususa ifilimu emnyama ➤ Ukupholisha ➤ Ukwelashwa kokudaya ngaphambi kokudaya ➤ Ukudaya ➤ Ukuvalwa kwemigodi ➤ Ukomisa
Umehluko phakathi kwe-anodizing kanye ne-electrophoresis: I-anodizing iwuku-oxidation kuqala bese kuba umbala, kuyilapho i-electrophoresis iwukufaka umbala ngqo.
3. Ukugqoka Okune-Electrostatic Powder
Ngemishini yokufafaza ngempuphu kagesi, i-powder coating isetshenziswa ekubukekeni kwe-workpiece. Ngaphansi kwesenzo sikagesi oqinile, i-powder izomuncwa ngokulinganayo ekubukekeni kwe-workpiece ukuze yakhe i-powder coating. Ngemva kokubhaka okushisa okuphezulu, ukulinganisa kanye nokupholisa i-powder coating, kufezwa i-coating yokugcina enemiphumela ehlukene. Umphumela wokufafaza maqondana namandla omshini, ukunamathela, ukumelana nokugqwala, ukumelana nokuguga, njll., uphakeme kakhulu kunenqubo yokufafaza.

4. Ukufutha nge-fluorocarbon
Ukufutha nge-fluorocarbon uhlobo lokufutha nge-electrostatic, futhi kuwukufutha ngoketshezi. Ukusetshenziswa kokufutha nge-fluorocarbon kubhakwa nge-polyvinylidene fluoride resin njengesisekelo noma nge-aluminium powder yensimbi njengezinto zombala ezenziwe ngopende. Kukhona okulengisiwe nokulengisiwe kancane. Okulengisiwe kusho ukuthi ngesikhathi senqubo yokwelapha kanye nokufutha kanye nokulungisa i-aluminium, i-aluminium izolengisiwe. Ukufutha nge-fluorocarbon enekhwalithi ephezulu kunokukhanya kwensimbi, umbala obukhali kanye nomuzwa ocacile wezinhlangothi ezintathu.
Inqubo ukugeleza
Ukugeleza kwangaphambi kokwelashwa: Ukususa amafutha nokuhlanza i-aluminium ➤ Ukugeza ngamanzi ➤ Ukugeza nge-alkali (ukususa amafutha) ➤ Ukugeza ngamanzi ➤ Ukugeza nge-asidi ➤ Ukugeza ngamanzi ➤ I-Chroming ➤ Ukugeza ngamanzi ➤ Ukugeza ngamanzi ahlanzekile
Ukugeleza kokufutha: Ukufutha i-primer ➤ I-Topcoat ➤ Upende we-Glaze ➤ Ukubhaka (180 - 250℃) ➤ Ukulawulwa kwekhwalithi
Umehluko phakathi kokufutha ngempuphu kagesi kanye nokufutha nge-fluorocarbon: Ukufutha ngempuphu kuwukusebenzisa imishini yokufutha ngempuphu (umshini wokufutha nge-electrostatic) ukufutha ngempuphu ukuze kubonakale sengathi i-workpiece iyasebenza. Ngaphansi kwesenzo sikagesi oqinile, impuphu izonamathela ngokulinganayo ekubukekeni kwe-workpiece, yakha i-powder coating. Ukufutha nge-fluorocarbon uhlobo lokufutha nge-electrostatic futhi kuyindlela yokufutha ngoketshezi, ebizwa ngokuthi i-fluorocarbon spraying.
5. Ukudluliswa Kwezinhlamvu Zokhuni
Amaphrofayili okudlulisa okusanhlamvu kokhuni abhekisela kumaphrofayili lapho, ngokusekelwe esimisweni sokungena kokushisa okuphezulu kwe-sublimation ekupendeni nge-powder coating noma nge-electrophoresis, ngokushisa, ukucindezela, iphethini lokusanhlamvu kokhuni ephepheni lokudlulisa noma ifilimu yokudlulisa idluliselwa ngokushesha futhi ingena kumaphrofayili afuthwe noma afakwe i-electrophoresis. Amaphrofayili okusanhlamvu kokhuni akhiqizwayo anokuthungwa okucacile kanye nomuzwa onamandla wezinhlangothi ezintathu, obonisa kangcono umuzwa wemvelo wokusanhlamvu kokhuni futhi uyinto efanelekile yokonga amandla futhi enobungane nemvelo ukuze ithathe indawo yokhuni lwendabuko.
