Izizathu ezibangela umbala ongalinganiyo wefilimu ye-aluminium alloy oxide

Izinto ezintathu ezinokubangela ukuba umbala wefilimu ye-aluminiyam ye-oxide ayifani:

(1) Xa iprofayili ye-aluminium i-anodized, kukho ukungafani okuphawulekayo kwindawo yokusebenzela, i-slot swing range, i-edge kunye ne-central position, isisombululo soqhagamshelwano, uhlaziyo, kunye nokutshintshiselana, okukhokelela kwifilimu yombala ongalinganiyo. Amanyathelo okuthintela abandakanya uluhlu oluncinci lokujingi ngelixa i-anodizing iprofayili ye-aluminium kwaye mhlawumbi unyango olusisigxina, nangona ubushushu besisombululo esisezantsi kakhulu sinokubangela ukubunjwa kweemephu okanye amabala, angeyiyo into ejoliswe kuyo.

2 Umthengi kaninzi akayiqondi kakuhle le nto, abavelisi kufuneka benze okungakumbi ukucacisa umsebenzi, bachaze ukuba kutheni kwaye njani, ukuze baphephe ukungaqondi kakuhle.

(3)Imiba yokusebenza kwenkqubo

Ayizizo zonke izinto ezimdaka eziye zasuswa yifilimu yasekhaya yasekuqaleni kwaye unyango lwe-workpiece lwe-caustic lwalungonelanga;

Umphezulu usesisiseko emva kokufakwa kwealkali kuba ukusetyenzwa kokukhanya akwenziwanga kwangoko;

ukusebenzisana kwe-workpiece ngexesha lokudluliselwa kwezinto zangaphandle.

Xa ividiyo ibonisa umbala ongahambelaniyo, kufuneka kwenziwe isenzo esifanelekileyo ukulungisa umba ngee-engile ezininzi.

Impazamo umfundi ufowunela ebuza workpiece emva emva alkali etching conductive oxide film kunzima ukufumana izizathu ezibangelwa alkaline etching ulwelo aluminiyam ion accumulation iphezulu kakhulu, emva kokukhutshelwa ngaphandle izinto ezininzi kwaye kunzima ukwenza ifilimu oxide conductive, athathe akhawunti ukuba i-aluminiyam ephezulu ion isisombululo alkali etching, omnye uthe isisombululo umhlwa alkaline kakhulu kakhulu. Kodwa isantya sokubola kwealkali asikhawulezi. Emva koko umbhali ucebisa ukutshintsha isisombululo somhlwa kwealkali, kuba emva kokuba ulwelo lwealkaline etching esetyenziselwa ixesha elide luya kuqokelelwa ion i-aluminium engaphezulu, i-ion ze-aluminium phezu komphezulu we-workpiece kunzima ukuyikhupha, ngaloo ndlela ichaphazela umphezulu we-aluminium kunye ne-conductive oxide solution contact, ngaloo ndlela ichaphazela ukubunjwa kwefilimu ye-oxide. Enye ingcebiso kukuba, ukuba ukutshintshwa okungenamiqathango kwesisombululo se-alkaline etching, i-workpiece emva kokusikwa kwealkali emva kokuhlanjululwa kwamanzi ngokukhawuleza emva kokuhamba kwamanzi okuhlamba, kunye nokukhanya kwi-hydrofluoric acid equlethe i-nitric acid egxininisiweyo, emva koko uhlambe ngokucokisekileyo emva kokuqhuba unyango lwe-oxidation. Emva kokuba abafundi bafowunele bathi emva kwe-alkali etching ngamanzi ashushu kwaye umphumo ulungile kakhulu. Umbhali ngamava, kwaye emanzini ashushu emva kwamanzi ashushu kwaye ngokukhawuleza antywiliselwe emanzini ngokukhawuleza ashiye, ukukhusela i-workpiece ngokumisa ngenxa ye-oxidation kunye nokuchaphazela ukubunjwa kwefilimu ye-conductive oxide.
