Daim ntawv thov teb ntawm anodized aluminium oxide
Anodized aluminium oxide muaj ntau yam kev siv, xws li tiv thaiv satellites los ntawm qhov chaw hnyav.Siv rau cov tsev siab siab thoob plaws ntiaj teb, muab kev txaus nyiam, tsis tshua muaj kev tswj xyuas, thiab cov khoom siv sab nrauv zoo heev, lub ru tsev, kab hlau rhuav phab ntsa, qab nthab, pem teb, escalators, chaw tos txais, thiab ntaiv hauv skyscrapers thiab cov tsev lag luam thoob ntiaj teb.
Tsis tas li ntawd, anodized aluminium oxide yog siv dav hauv cov khoom siv hauv computer, cov khoom pov thawj kev lag luam, cov cuab yeej tshawb fawb, thiab nthuav cov qauv ntawm cov khoom siv hauv tsev, cov khoom siv, thiab cov khoom siv hauv tsev.
Pom zoo ib puag ncig muaj kev nyab xeeb, uas yuav luag tsis muaj teeb meem rau av, huab cua, lossis dej.
Noj cov ntaub ntawv xov tooj txhuas lossis cov rooj plaub hub raws li Cheng Shuo rooj plaub, cov txheej txheem siv anodizing feem ntau yog raws li hauv qab no:
1. Daim iav anodizing ua tshuab:
CNC machining→Daim iav polishing 1→Daim iav polishing 2→Daim iav polishing 3→Oxidation→Daim iav polishing 4→Daim iav polishing 5→CNC machining→Thib ob oxidation→Kev kho tus ntiv tes tiv thaiv
2. Hard oxidation nto kho tshuab
Kev siv technology: CNC machining→polishing→sandblasting→nyuaj oxidation
Cov khoom zoo: Lub hardness ntawm qhov zoo tib yam oxidation ntawm aluminium alloy yog nyob ib ncig ntawm HV200, thiab lub hardness ntawm hard oxidation tuaj yeem ncav cuag HV350 lossis siab dua;
Lub thickness ntawm oxide zaj duab xis yog 20-40um;Kev rwb thaiv tsev zoo: tawg voltage tuaj yeem ncav cuag 1000V;Zoo hnav tsis kam.
3. Oxidized nto kho tshuab rau gradient xim
Kev siv technology: CNC machining→polishing→sandblasting→gradual oxidation→polishing
Cov khoom zoo: Cov khoom xim muaj xim ntawm lub teeb mus rau qhov tsaus ntuj, nrog rau kev nkag siab zoo ntawm cov xim hierarchy;Cov tsos zoo nrog glossy zoo nkauj.
4. Dawb oxidation nto kho tshuab
Kev siv technology: CNC machining→polishing→dawb oxidation
Cov khoom zoo: Cov xim ntawm cov khoom yog dawb huv thiab muaj cov nyhuv zoo;Cov tsos zoo nrog glossy zoo nkauj.
5.Puab polishing dawb high-speed txiav tshuab
Ua tshuab: high-speed txiav CNC machining→sandblasting→oxidation
Cov khoom lag luam zoo: Kev ua haujlwm ceev ntawm cov cuab yeej tuaj yeem ncav cuag 40000 rpm, qhov roughness ntawm qhov zoo li tuaj yeem ncav cuag Ra0.1, thiab tsis muaj qhov pom tseeb riam kab ntawm cov khoom;
Qhov saum npoo ntawm cov khoom tuaj yeem ncaj qha sandblasted thiab oxidized yam tsis muaj riam, txo cov nqi polishing ntawm cov khoom.
Anodizing txheej txheem ntws ntawm lub xov tooj ntawm tes roj teeb npog
Kev kho tshuab→ntxuav→sandblasting→Kev tshem tawm roj (acetone)→ntxuav dej→alkaline corrosion (sodium hydroxide)→ntxuav dej→Kev tshem tawm tshauv (sulfuric acid los yog phosphoric acid, los yog sib tov ntawm ob acids)→ntxuav dej→anodizing (sulfuric acid)→xim→qhov sealing.
Alkali corrosion lub hom phiaj: tshem tawm cov oxide zaj duab xis tsim nyob rau saum npoo ntawm aluminium alloy nyob rau hauv cov huab cua, thiaj li tsim ib tug uniform activated nto;Ua kom lub ntsej muag ntawm cov khoom siv aluminium du thiab zoo ib yam, thiab tshem tawm me ntsis khawb thiab khawb.
Thaum lub sij hawm alkaline etching txheej txheem, cov hlau compound impurities muaj nyob rau hauv lub aluminium alloy hardly koom nyob rau hauv cov tshuaj tiv thaiv thiab tsis yaj nyob rau hauv cov tshuaj alkaline etching.Lawv tseem nyob ntawm qhov chaw ntawm cov khoom siv txhuas, ua rau xoob grey dub txheej txheej.Feem ntau yog tsim los ntawm cov ntsiab lus alloy lossis impurities xws li silicon, tooj liab, manganese, thiab hlau uas yog insoluble hauv alkaline kua.Qee lub sij hawm nws tuaj yeem so nrog cov ntaub ntub dej, tab sis feem ntau nws yuav tsum tau yaj thiab tshem tawm los ntawm cov txheej txheem tshuaj, uas yog, tshem cov tshauv.
