Vim li cas D txhuam Tiab Nuj Nqi Txhawm tsis muaj dimin?
Aluminium nws tus kheej yog ib qho muaj zog corrosion-resistant substance . T nws nto ntawm txhuas yuav ua rau txhuas oxidation tom qab ntsib cov pa uas yuav maj mam tshem tawm nws tsis kam ntev ntev. Tsis tas li ntawd, nws yog ib qho tseem ceeb rau cov kua tshuaj acidic acid , kua qaub yuav ua kom puas txheej txhuas duav, ces peb yuav tsum tau kho anodized nta kho dua thiab ntxiv ib txheej ntawm cov yeeb yaj kiab tiv thaiv ntawm qhov yuav ua rau kom muaj kev sib zog ntawm qhov chaw, txhuas yeeb nkab los yog txhuas yam khoom uas nws qhov kev ua haujlwm tsis muaj zog, kev ua haujlwm, kev ua haujlwm, kev tiv thaiv, kev kub cev, thiab lwm yam. Lub nodized kho ntawm txhuas leeg yog feem ntau nqa hauv acidic electrolyte, nrog txhuas ua anode. Hauv cov txheej txheem electrolysis, cov cua ntawm cov pa oxygen thiab cov txhuas siv los tsim cov yeeb yaj kiab anodized. Qhov pib ntawm zaj yeeb yaj kiab no tsis zoo, tab sis muaj qee qhov tsis kam, tiam sis qhov tsis zoo oxygen ions nyob rau hauv lub ntshiab tseem tuaj yeem ncav cuag qhov txhuas ntu mus txuas ntxiv rau ib qho oxide zaj duab xis. Raws li cov thickness ntawm cov zaj duab xis tsub, qhov tsis ua haujlwm loj thiab cov electrolytic tam sim no yuav me. Nyob rau lub sij hawm no, txheej txheej ntawm cov yeeb yaj kiab anodized yuav siv tshuaj lom neeg xaus nrog cov electrolyte. Thaum tus tshaj tawm ntawm oxide nyob rau saum npoo ntawm cov txhuas yog maj balanced nrog tus nqi ntawm cov tshuaj dissolution, cov zaj duab xis anodized yuav ncav cuag qhov siab tshaj plaws nyob rau hauv qhov kev ntsuas no hauv qhov kev hloov ntawm electrolytic. Lub zeem muag ntawm aluminium yog porous, nws yog yooj yim rau adsorb dye thiab cov ntaub ntawv dawb, ces nws yuav dyed thiab nws cov adornment yog khees me ntsis lawm. Cov tshuaj oxidation tuaj yeem txhim kho nws qhov kev xeb thiab corrosion tiv thaiv tom qab kho cov dej kub, kub kub los yog ntsev npauj npaim.
