Dab tsi yog qhov tseem ceeb cuam tshuam rau qhov zoo ntawm Anodic Oxidation Zaj duab xis ntawm Aluminium Profiles?

Lub ntsiab tseem ceeb cuam tshuam rau qhov zoo ntawm anodic oxidation zaj duab xis ntawm aluminium profiles yog raws li nram no:

(1) Tam sim no qhov ntom ntom: nyob rau hauv ib qho kev txwv, qhov ceev tam sim no nce, qhov kev loj hlob ntawm zaj duab xis nce, lub sij hawm oxidation shortens, lub pore ntawm zaj duab xis yog ntau, thiab nws yog ib qho yooj yim rau xim, thiab hardness thiab hnav kuj nce; Yog tias qhov ceev tam sim no siab dhau lawm, vim yog qhov cuam tshuam ntawm Joule tshav kub, qhov chaw ntawm qhov chaw yuav dhau los thiab qhov kub ntawm cov tshuaj hauv zos yuav nce, thiab qhov kev sib cais ntawm cov yeeb yaj kiab yuav nce, thiab cov khoom yuav raug hlawv. Yog tias qhov ceev ceev tam sim no tsawg dhau, kev sib deev ntawm kev ua yeeb yaj kiab yog qeeb, tab sis cov yeeb yaj kiab yog cog, hardness thiab hnav tsis kam yog txo.

Aluminium oxidation, siv rau kev tiv thaiv, kho kom zoo nkauj thiab kev kho kom zoo nkauj ntshiab, kev txwv sab saud ntawm kev tso cai, uas yog, 20 feem pua ​​​​ntawm sulfuric acid li electrolyte.

② Oxidation lub sij hawm: qhov kev xaiv ntawm oxidation lub sij hawm nyob ntawm electrolyte concentration, kub, anode tam sim no ceev thiab yuav tsum tau cov zaj duab xis thickness. Nyob rau hauv tib lub sijhawm, cov yeeb yaj kiab loj hlob yog proportional rau lub sijhawm oxidation thaum qhov ceev tam sim no tsis tu ncua. Txawm li cas los xij, thaum cov yeeb yaj kiab loj hlob mus rau qee qhov tuab, cov yeeb yaj kiab kuj nce ntxiv, uas cuam tshuam rau cov conductivity, thiab cov zaj duab xis dissolution nce vim qhov kub thiab txias, yog li cov zaj duab xis loj hlob yuav maj mam txo, kom txog thaum nws tsis nce ntxiv.

③ Sulfuric acid concentration: feem ntau 15 feem pua ​​-- 20 feem pua. Nrog rau qhov nce ntawm cov concentration, qhov sib cais ntawm cov yeeb yaj kiab nce, qhov kev loj hlob ntawm cov yeeb yaj kiab txo qis, qhov porosity ntawm zaj duab xis yog siab, lub peev xwm adsorption muaj zog, elastic, zoo dyeing (yooj yim rau xim tsaus), tab sis lub hardness. thiab hnav tsis kam yog me ntsis zuj zus; Thaum cov concentration ntawm sulfuric acid txo, qhov kev loj hlob ntawm oxide zaj duab xis yog ceev, lub porosity ntawm oxide zaj duab xis yog tsawg, hardness yog siab dua, thiab hnav kuj zoo dua.

(4) electrolyte kub: electrolyte kub muaj kev cuam tshuam zoo ntawm oxide zaj duab xis. Nrog rau qhov kub thiab txias, zaj duab xis dissolution tus nqi nce thiab cov zaj duab xis thickness txo. Thaum qhov kub thiab txias yog 22-30 degree, cov zaj duab xis tau yog mos thiab muaj peev xwm adsorption zoo, tab sis tsis zoo hnav tsis kam. Thaum qhov kub siab tshaj 30 degree, zaj duab xis yuav xoob thiab tsis sib xws, qee zaum txawm tias tsis txuas ntxiv, thiab qhov hardness tsawg, yog li nws poob nws cov nqi siv; Thaum qhov kub ntawm 10 thiab 20 degree, oxide zaj duab xis yog ntxeem tau, muaj zog adsorption muaj peev xwm, thiab elastic, haum rau dyeing, tab sis lub hardness ntawm zaj duab xis yog tsawg, tsis zoo hnav tsis kam; Thaum qhov kub qis dua 10 degree, oxide zaj duab xis thickness nce, hardness siab, hnav tsis kam yog qhov zoo, tab sis porosity tsawg. Yog li ntawd, qhov kub ntawm electrolyte yuav tsum nruj me ntsis tswj thaum lub sij hawm tsim khoom. Ua kom tuab thiab tawv oxide zaj duab xis, nws yog ib qho tsim nyog yuav tsum tau txo qhov kev khiav hauj lwm kub, nyob rau hauv tus txheej txheem ntawm oxidation siv compressed cua nplawm thiab kuj tsis tshua muaj kub, feem ntau yog zero degree hard oxidation.

⑤ stirring thiab txav: tuaj yeem txhawb cov convection ntawm electrolyte, ntxiv dag zog rau cov nyhuv txias, xyuas kom meej qhov sib xws ntawm kev daws qhov kub thiab txias, yuav tsis ua rau qhov zoo ntawm oxide zaj duab xis vim qhov kub ntawm cov hlau hauv zos.

⑥ Impurities hauv electrolyte: yuav muaj Clˉ, Fˉ, NO3ˉ, Cu2 ntxiv, Al3 ntxiv, Fe2 ntxiv rau hauv cov electrolyte siv rau anodic oxidation ntawm txhuas. Clˉ, Fˉ, NO3ˉ tuaj yeem ua kom cov porosity ntawm daim nyias nyias, thiab qhov chaw yog ntxhib thiab xoob. Yog hais tias cov ntsiab lus ntawm Clˉ yuav tsum tsawg dua 0. Thaum Al3 ntxiv cov ntsiab lus nyob rau hauv cov electrolyte ntau tshaj ib tug nqi, nws feem ntau ua rau lub workpiece nto tshwm dawb me ntsis los yog macular dawb blocks, thiab ua rau cov adsorption kev ua tau zoo ntawm cov zaj duab xis poob, thiab nws yog ib qho nyuaj rau dye (Al3 ntxiv yuav tsum tsawg dua. 20 g / L); Thaum cov ntsiab lus ntawm Cu2 ntxiv mus txog 0.02g / L, cov kab txaij tsaus lossis cov pob dub tshwm rau ntawm cov yeeb yaj kiab oxide. Si2 ntxiv feem ntau muaj nyob rau hauv cov electrolyte nyob rau hauv lub xeev ncua, uas ua rau cov electrolyte me ntsis pos huab thiab adsorbed rau ntawm zaj duab xis raws li ib tug xim av hmoov.

(7) Aluminium alloy muaj pes tsawg leeg: feem ntau, lwm cov ntsiab lus nyob rau hauv txhuas hlau ua rau qhov zoo ntawm cov zaj duab xis poob, thiab oxide zaj duab xis yog tsis ntshiab txhuas nyob rau hauv thickness, hardness yog tsawg, txawv Cheebtsam ntawm txhuas alloy, nyob rau hauv anodic oxidation kev kho mob yuav tsum. them sai sai rau tsis tuaj yeem nqa tawm hauv tib lub qhov.
