Cov laj thawj tom qab cov xim tsis sib xws ntawm aluminium alloy oxide zaj duab xis

Peb qhov ua rau ntawm aluminium profile oxide zaj duab xis xim tsis sib xws:

(1) Thaum cov txhuas profile yog anodized, muaj qhov sib txawv tseem ceeb hauv thaj chaw ua haujlwm, qhov viav vias ntau yam, ntug thiab qhov chaw nruab nrab, kev daws teeb meem, hloov kho, thiab pauv, uas ua rau cov xim tsis sib xws. Kev tiv thaiv kev tiv thaiv muaj xws li lub viav vias me me thaum lub sij hawm anodizing aluminium profile thiab tej zaum kev kho zoo li qub, txawm hais tias qhov ntsuas kub qis dhau tuaj yeem ua rau daim duab qhia kev tsim lossis pob, uas tsis yog qhov xav tau.

(2) Thaum lub txhuas clad qhov chaw raug puas tsuaj, los ntawm kev txiav tawm, sab nrauv alclad belongs rau cov zoo txhuas, nyob rau hauv lub txheej txheej yog lwm yam txhuas, ob txhuas sib txawv, yog li cov oxidation tom qab "benign vitiligo" zoo li me ntsis. Cov neeg siv khoom feem ntau tsis nkag siab txog qhov tshwm sim no, cov neeg tsim khoom yuav tsum ua ntau ntxiv los piav qhia txog kev ua haujlwm, piav qhia vim li cas thiab yuav ua li cas, txhawm rau zam kev nkag siab yuam kev.

(3) Cov teeb meem nrog cov txheej txheem ua haujlwm

Tsis yog tag nrho cov av tau raug tshem tawm los ntawm lub zos thawj zaj duab xis thiab lub workpiece txoj kev kho caustic tsis txaus;

Qhov saum npoo tseem yog qhov yooj yim tom qab alkali etching txij li lub teeb ua haujlwm tsis siv tam sim;

lub workpiece kev sib cuam tshuam thaum sib kis nrog cov khoom siv sab nraud.

Thaum ib daim vis dis aus nthuav tawm cov xim tsis sib xws, yuav tsum ua kom tsim nyog los daws qhov teeb meem ntawm ntau lub ces kaum.

Ua txhaum tus nyeem ntawv hu nug cov khoom ua haujlwm tom qab alkali etching conductive oxide zaj duab xis yog qhov nyuaj kom tau txais cov laj thawj tshwm sim los ntawm alkaline etching kua aluminium ion accumululation siab dhau, tom qab tsis suav nrog ntau yam thiab nws nyuaj rau tsim cov yeeb yaj kiab oxide, coj mus rau hauv account seb lub siab aluminium ions alkali etching tov, lwm tus hais tias alkaline corrosion tov yog tuab heev. Tab sis alkali corrosion ceev tsis ceev. Tom qab ntawd tus kws sau ntawv pom zoo hloov cov tshuaj alkaline corrosion, vim tias tom qab alkaline etching kua siv ntev dhau lawm yuav aluminium ion tsub zuj zuj ntawm ntau dhau, aluminium ions ntawm qhov chaw ntawm lub workpiece yog qhov nyuaj rau elution, yog li cuam tshuam rau aluminium nto thiab conductive oxide tov, yog li cuam tshuam qhov tsim ntawm oxide zaj duab xis. Lwm qhov kev tawm tswv yim yog tias yog tias tsis muaj kev hloov pauv ntawm alkaline etching tov, lub workpiece tom qab alkali etching tom qab dej yaug tam sim ntawd tom qab cov dej ntws yaug, thiab tom qab ntawd lub teeb nyob rau hauv hydrofluoric acid uas muaj concentrated nitric acid, ces yaug kom huv si tom qab kev kho oxidation. Tom qab cov neeg nyeem mus rau xov tooj hais tias tom qab alkali etching nrog dej kub thiab cov nyhuv yog zoo heev. Tus sau yog cov kev paub dhau los, thiab hauv cov dej kub tom qab dej kub thiab tam sim ntawd tso rau hauv dej sai sai, los tiv thaiv lub workpiece los ntawm qhuav vim oxidation thiab cuam tshuam rau kev tsim ntawm conductive oxide zaj duab xis.
