Electrochemical oxidation ntawm hlau los yog hlau. Aluminium thiab nws cov alloy nyob rau hauv cov electrolyte thiab tshwj xeeb technology mob, vim yog cov teebmeem ntawm lub siab tam sim no, nyob rau hauv cov khoom txhuas (anode) rau ib txheej ntawm oxide zaj duab xis tsim txheej txheem. Anodic oxidation thiab yog tias tsis tau teev, feem ntau yog hais txog cov tshuaj sulfuric acid anodizing.

为了 克服 铝 铝 服 陷 陷 陷 陷 陷 陷 陷 陷 陷 陷 陷 陷 陷 陷 陷 陷 陷 陷 陷 陷 陷 陷 陷 陷 陷 陷 陷 陷 陷 陷 陷 陷 陷 陷 陷 陷 陷 陷 陷 陷Kwv yees.

Yuav kom kov yeej cov kev tsis haum ntawm aluminium alloy tawv hardness, hnav tsis ua hauj lwm thiab ua rau, nthuav dav rau daim ntawv thov, muab kev pab cuam lub neej, qhov kev kho tshuab ntws tau ua ib qho tseem ceeb hauv kev siv cov txhuas aluminium, thiab anode oxidation technology tam sim no feem ntau yog siv dav thiab zoo tshaj plaws.

 

Anodic oxidation ntawm aluminium yog ib hom kev electrolytic oxidation txheej txheem, nyob rau hauv cov txheej txheem no, txhuas thiab aluminium alloys yog feem ntau hloov mus rau ib txheej oxide zaj duab xis, zaj duab xis no muaj kev tiv thaiv, zoo nkauj thiab lwm yam kev ua haujlwm. Anodic oxidation los ntawm lub ntsiab txhais ntawm txhuas, tsuas yog cov cim ntawm qhov no ntawm cov txheej txheem ntawm anodic oxide zaj duab xis.

金 属 属 膜 膜 膜 膜 膜 膜 膜 膜 膜 膜 膜 膜 膜 膜 膜 膜 膜 膜 膜 膜 膜 膜 膜 膜 膜 膜 膜 膜 膜 膜 膜 膜 膜 膜 膜 膜 膜 膜 膜 膜 膜 膜Tiv thaiv kom tsis txhob muaj teeb meem nrog lwm tus neeg, xws li cov kev lag luam, kev sib txuas lus, kev lag luam, kev sib txuas lus, kev txhim kho, thiab kev sib txuas lus. Yeej muaj 5 ~ 30 leej, qhov ntev tshaj li 25 ~ 150 leej. Qhov zoo tshaj plaws, muaj ntau npaum li cas thiab muaj ntau tshaj li 50 ~ 500千克 / 平方 多米, 良好 的 耐热 性, 硬 环 的 微 增 增长 增长 23 万, 高度 建设 支持 机制, 增强 高 2000V, 增强 蚀,, = = 0.03NaCl 盐雾 中 经 几千 小时化 蚀 蚀 孔 孔 孔 孔 孔 孔 孔 孔 孔 孔 孔 孔 孔 孔 孔 孔 孔 孔 孔 孔 孔 孔 孔 孔 孔 孔 孔 孔 孔 孔 孔 孔 孔 孔 孔 孔 孔 孔 孔 孔 孔 孔 孔 孔 孔 孔 孔 孔 孔 孔 Cov kws tshawb fawb ntawm cov neeg muaj koob muaj npe, muaj teeb meem ntau tshaj li cov qauv siv, cov khoom siv lub tshuab, cov khoom siv, cov khoom siv, cov qauv siv thiab cov qauv tsim tawm Yooj yim.

Cov hlau lossis cov hlab hlau thoob plaws raws li kev kuaj zoo, siv cov txujci electroplating los ua cov pa oxide saum npoo av. Cov hlau oxide zaj duab xis hloov lub zog ntawm lub xeev thiab cov khoom, xws li ntog xim, txhim kho kev txhim kho corrosion, enhanced hnyav thiab hardness, kev tiv thaiv ntawm hlau nto. Piv txwv, anodized aluminium, aluminium thiab nws cov alloy yog teem nyob rau hauv qhov sib piv cov electrolyte (xws li sulfuric acid) raws li anode, nyob rau hauv tej yam kev mob thiab tam sim no, electrolysis. Anode txhuas los yog nws cov oxidation alloy, tsim los ntawm alumina txheej saum npoo, cov thickness yog 5 mus rau 30 microns, nyuaj anodic oxidation zaj duab xis tuaj yeem ncav 25 ~ 150 micron. Anodized aluminium thiab nws cov alloy, txhim kho qhov nyuaj thiab hnav kev ua haujlwm, mus txog 250 ~ 500 kg / mm2, zoo kub cev, siab melting point ntawm 2320K nyuaj anodic oxidation zaj duab xis, zoo insulating vaj tse, siab tawg voltage txog 2000V, enhanced corrosion kuj, ntsev huab cua nyob hauv Omega = 0.03NaCl tom qab txhiab lub sij hawm uas tsis muaj corrosion. Muaj ntau tus dej uas ntxeem tau oxide, yuav nqus tau txhua yam roj hmab, tsim rau kev tsim khoom ntawm lub tog raj kheej lossis lwm yam khoom hnav; Microporous membrane adsorption muaj peev xwm muaj xim nyob rau hauv ntau yam xim zoo nkauj xim. Nonferrous hlau los yog nws cov hlau (aluminium, magnesium thiab nws cov alloy) yuav tsum anodized, qhov no yog dav siv nyob rau hauv machinery qhov chaw, aircraft, lub tsheb yam, precision twj paj nruag thiab cov khoom siv xov tooj cua, niaj hnub khoom thiab vaj tsev kho kom zoo nkauj etc ..

Ib qho kev sib koom tes los ntawm kev loj hlob zoo, Qhov ntsej muag, cov zaub ntsuab, kua zaub, kua zaub, kua zaub ntsuab, kua zaub ntsuab, kua zaub ntsuab, kua zaub ntsuab, 让 铝 和 铅板Nrog rau cov menyuam kawm ntawv, cov khoom noj khoom haus thiab cov khoom noj khoom haus.

Feem ntau hais lus, qhov anode yog ua los ntawm txhuas los yog txhuas hlau ua ib qho kev ua lag luam, cathode tau xaiv ua hlau, txhuas thiab ua rau lawv nyob hauv aqueous sulfuric acid, oxalic acid, muaj, chromic acid, electrolysis, cia lub nplaim ntawm txhuas thiab ua rau daim ntawv oxide zaj duab xis. Nyob rau hauv cov acid, yog feem ntau dav siv sulfuric acid anodic oxidation ntawm.

Qiv: Muaj feem xyuam rau txoj hlua khab nias los ntawm kev txhim kho kev lag luam los ntawm kev ua hauj lwm nrog kev lag luam los ntawm kev ua lag luam.

Nyhuv: nrog lwm lub zog nyob rau hauv txoj kev loj hlob ntawm kev nplua zog thiab inorganic txheej tiv thaiv zoo nkauj rwb thaiv tsev nrog cov organic txheej
