Sababaha ka dambeeya midabka aan sinnayn ee filimka aluminium alloy oxide

Saddexda sababood ee suurtogalka ah ee midabka aluminium profile oxide midabka filimka maaha mid isku mid ah:

(1) Marka profile aluminium waa anodized, waxaa jira farqi weyn oo ku saabsan aagga workpiece, booska lulid, gees iyo booska dhexe, xiriir xal, update, iyo sarrifka, taas oo horseedaysa in filim midabka aan sinnayn. Tallaabooyinka ka-hortagga waxaa ka mid ah kala duwanaansho lulid yar marka la anodizing profile aluminium iyo laga yaabaa in daawaynta taagan, in kasta oo heerkulka xal aad u hooseeya uu keeni karo samaynta khariidad ama dhibco, taas oo aan ahayn waxa loogu talagalay.

(2) Marka qaybaha aluminium ee aluminiumku ay ku hoos jireen burburka, iyada oo la jarayo, alclad dibadda ah ayaa iska leh aluminium tayo sare leh, lakabka gudaha ee ku xiran waa aluminium kala duwan, laba kala duwanaansho aluminium ah, sidaas darteed oksaydhka ka dib "vitiligo benign" sida dhibco. Macaamiilku inta badan ma fahmaan dhacdadan, warshadeeyayaashu waa inay sameeyaan wax badan si ay u sharxaan shaqada, sharaxaan sababta iyo sida, si looga fogaado isfaham la'aan.

(3) Arrimaha ku saabsan hawlgalka habka

Wasaq oo dhan lagama wada saarin filimkii asalka ahaa ee deegaanka iyo daawaynta caustic ee shaqada waxay ahayd mid aan ku filnayn;

Dusha sare weli waa aasaaska ka dib etching alkali tan iyo farsamaynta iftiinka aan isla markiiba la codsado;

dhexgalka workpiece ee inta lagu guda jiro gudbinta la walxaha dibadda.

Marka fiidiyowgu muujiyo midab aan is-waafaqayn, ficil ku habboon waa in la sameeyaa si arrinta looga hadlo dhinacyo badan.

Qalad akhristaha wacaya weydiinaya workpiece by ka dib markii alkali etching conductive oxide film waa ay adag tahay in la helo sababaha ay keento alkali etching dareere aluminium ion raasamaal waa mid aad u sarreeya, ka dib marka laga reebo arrimo badan oo ay adag tahay in la sameeyo filimka oxide conductive ah, qaado galay. xisaabta haddii aluminium ion sare alkali etching xal, kale ayaa sheegay in xal daxalka alkaline waa mid aad u qaro weyn. Laakiin xawaaraha daxalka alkali ma aha mid degdeg ah. Markaas qoraagu soo jeedinayaa beddelo xal daxalka alkaline, maxaa yeelay, ka dib markii dareere etching alkaline loo isticmaalo muddo aad u dheer doonaa raasamaal ion aluminium ee xad-dhaaf ah, ions aluminium on dusha workpiece waa adag tahay in elution, sidaas saamayn ku dusha aluminium iyo xiriir xal oksaydhka conductive, sidaas darteed saameynaya sameynta filimka oxide. Soo jeedin kale ayaa ah in haddii beddelka shuruud la'aanta ah ee xalalka etching alkaline, workpiece ka dib etching alkali ka dib biyo raaci isla markiiba ka dib socodka biyaha raaci, ka dibna iftiin ah in hydrofluoric acid ka kooban nitric acid, ka dibna si fiican u raaci ka dib markii la sameeyo daaweynta oxidation. Ka dib markii akhristayaasha ay telefoon u sheegeen ka dib markii alkali etching biyo kulul iyo saamaynta waa mid aad u wanaagsan. Qoraagu waa waayo-aragnimada, iyo in biyo kulul ka dib markii biyaha kulul iyo isla markiiba quusin biyaha si deg deg ah ka tago, si looga hortago workpiece by qalalan ay sabab u Oxidation iyo saamayn formation of film oxide conductive.
