Izizathu zombala ongalingani wefilimu ye-aluminium alloy oxide

Izimbangela ezintathu ezingenzeka zombala wefilimu ye-aluminium oxide ayifani:

(1)Lapho iphrofayili ye-aluminium i-anodized, kuba nokungafani okuphawulekayo endaweni yokusebenzela, ububanzi be-slot swing, unqenqema nendawo emaphakathi, ukuthintana nesixazululo, ukuvuselela, nokushintshana, okuholela efilimini yombala engalingani. Izinyathelo zokuvimbela zihlanganisa ububanzi bokujika kancane ngenkathi i-anodizing iphrofayela ye-aluminium futhi mhlawumbe nokwelashwa okumile, nakuba izinga lokushisa eliphansi kakhulu lesisombululo lingabangela ukwakheka kwemephu noma amabala, okungekona lokho okuhlosiwe.

(2) Lapho izingxenye eziboshwe nge-aluminium zicekelwa phansi, ngokunqunywa, i-alclad yangaphandle ingeye-aluminium yekhwalithi ephezulu, ungqimba lwangaphakathi oluvalekile luyi-aluminium exubile, umehluko we-aluminium amabili, ngakho-ke i-oxidation ngemuva “kwe-vitiligo enobungozi” njengamachashaza. Ikhasimende ngokuvamile aliyiqondi kahle le nto, abakhiqizi kufanele benze okwengeziwe ukuze bachaze umsebenzi, bachaze ukuthi kungani futhi kanjani, ukuze bagweme ukungaqondi kahle.

(3) Izinkinga ngokusebenza kwenqubo

Akuwona wonke ukungcola okwasuswa ifilimu yasekuqaleni yendawo kanye nokwelashwa kwe-caustic ye-workpiece kwakungenele;

Ingaphezulu lisayisisekelo ngemva kokusikwa kwe-alkali njengoba ukucubungula ukukhanya akusetshenziswa ngaso leso sikhathi;

ukusebenzisana kwe-workpiece ngesikhathi sokudlulisa ngezinto zangaphandle.

Uma ividiyo ibonisa umbala ongashintshi, kufanele kwenziwe isenzo esifanele ukuze kubhekwane nenkinga ngama-engeli amaningi.

Iphutha umfundi ubiza ecela workpiece by ngemva alkali etching conductive oxide ifilimu kunzima ukuthola izizathu ezibangelwa alkaline etching liquid aluminium ion accumulation liphezulu kakhulu, ngemva ukukhishwa izici eziningi futhi kunzima ukwakha conductive oxide ifilimu, thatha akhawunti ukuthi i-aluminium ion ephezulu ye-alkali etching solution, enye yathi isixazululo se-alkaline corrosion sikhulu kakhulu. Kodwa ijubane lokugqwala kwe-alkali alisheshi. Khona-ke umbhali uphakamisa ukushintsha isixazululo sokugqwala kwe-alkali, ngoba ngemva kokuba uketshezi lwe-alkaline etching olusetshenziswe isikhathi eside luzoqongelela i-aluminium ion ngokweqile, i-aluminium ion ebusweni bomsebenzi onzima kunzima ukuyikhipha, ngaleyo ndlela ithinte i-aluminium surface kanye ne-conductive oxide solution contact, ngaleyo ndlela kuthinte ukwakheka kwefilimu ye-oxide. Esinye isiphakamiso siwukuthi uma ukushintshwa okungenamibandela kwesisombululo se-alkaline etching, isiqeshana sokusebenzela ngemva kokufakwa kwe-alkali ngemva kokugeza kwamanzi ngokushesha ngemva kokugeleza kwamanzi hashaza, bese kuba ukukhanya ku-hydrofluoric acid equkethe i-nitric acid egxilile, bese ugeza kahle ngemva kokwenza ukwelashwa kwe-oxidation. Ngemva kokuba abafundi ngocingo wathi ngemva alkali etching ngamanzi ashisayo futhi umphumela muhle kakhulu. Umbhali isipiliyoni, futhi emanzini ashisayo ngemva kwamanzi ashisayo futhi ngokushesha wacwiliswa emanzini ngokushesha shiya, ukuvimbela workpiece by omile ngenxa oxidation futhi kuthinte ukwakheka conductive oxide ifilimu.
