Anodizing ndi chiyani

Akamaliza makina opanga makina a Chengshuo Hardware atamaliza kuyesa molondola komanso kuyesa kukula kwazitsulo, dipatimenti yathu yokonza zinthu idzachita bwino kwambiri pambuyo pokonza zitsulo malinga ndi malo omwe makasitomala amagwiritsa ntchito zitsulo.

Anthu ambiri amaganiza za chithandizo chapamwamba, ndipo amangochiwona ngati chomaliza chokongoletsera monga utoto ndi zokutira za ufa kuti zigawozo ziziwoneka zokongola kwambiri ndikusintha mtundu.Ndipotu, chithandizo chapamwamba sichiri chokongoletsera.Mankhwala osiyanasiyana apamwamba amachitira kunja kwazitsulo zazitsulo pogwiritsa ntchito wosanjikiza woonda wowonjezera pamwamba.Chithandizo choyenera chapamwamba chingathandize mitundu yosiyanasiyana yazitsulo zokonzedwa bwino kuti zitetezedwe bwino pamalo ogwiritsira ntchito (monga kukana dzimbiri, kuchepetsa dzimbiri), kuteteza zitsulo, ndi kukwaniritsa cholinga chotalikitsa moyo wautumiki.

Lero tikudziwitsani za kupanga aluminiyamu yopanga ndi chithandizo chapamwamba, anodizing, chomwe Chengshuo Hardware ndi aluso kwambiri.

Kodi anodizing ndi chiyani?

Anodizing ndi njira ya electrochemical yomwe imatembenuza chitsulo pamwamba kuti chikhale chokongoletsera, chokhazikika, komanso chopanda dzimbiri cha anode oxide pamwamba.Aluminiyamu ndi yoyenera kwambiri pa anodizing, ngakhale zitsulo zina zopanda chitsulo monga magnesium ndi titaniyamu zimathanso kudzozedwa.

Mu 1923, anodizing idagwiritsidwa ntchito koyamba pamafakitale kuti ateteze zida za aluminiyamu za ndege zapanyanja kuti zisawonongeke.M'masiku oyambirira, chromic acid anodizing (CAA) inali njira yokondedwa, yomwe nthawi zina imatchedwa ndondomeko ya Bengough Stuart, monga momwe akufotokozedwera mu UK Defense Specification DEF STAN 03-24 / 3.

Masiku ano otchuka gulu la anodizing

Anodizing yakhala ikugwiritsidwa ntchito kwambiri m'makampani kwa nthawi yayitali.Pali njira zambiri zogwiritsira ntchito mayina osiyanasiyana, ndipo pali njira zingapo zogawa zomwe zitha kufotokozedwa mwachidule motere:

Zosankhidwa ndi mtundu wamakono: DC anodizing;AC anodizing;Ndipo zimachitika anodizing panopa, amene angafupikitse kupanga nthawi kukwaniritsa makulidwe chofunika, kupanga filimu wosanjikiza wandiweyani, yunifolomu ndi wandiweyani, ndi bwino kwambiri kukana dzimbiri.

Malinga ndi electrolyte, akhoza kugawidwa mu asidi sulfuric, asidi oxalic, asidi chromic, asidi wosanganiza, ndi mwachibadwa wachikuda anodic makutidwe ndi okosijeni ndi sulfonic organic zidulo monga yankho lalikulu.Oxalic acid anodizing inali yovomerezeka ku Japan mu 1923 ndipo kenako idagwiritsidwa ntchito kwambiri ku Germany, makamaka pomanga ntchito.Anodized aluminium oxide extrusion inali zomangira zodziwika bwino m'zaka za m'ma 1960 ndi 1970, koma kenako zidasinthidwa ndi mapulasitiki otsika mtengo ndi zokutira za ufa.Njira zosiyanasiyana za phosphoric acid ndi chimodzi mwazinthu zomwe zachitika posachedwa pakupangira zida za aluminiyamu zomwe zimagwiritsidwa ntchito polumikizana kapena kupenta.Zosintha zosiyanasiyana zovuta mu anodic oxidation process pogwiritsa ntchito phosphoric acid zikusinthabe.Mchitidwe wamagulu ankhondo ndi mafakitale ndikuyika m'magulu a anodizing potengera mawonekedwe a zokutira kuwonjezera pakuzindikira chemistry.

Malinga ndi katundu wa filimu wosanjikiza, akhoza kugawidwa mu: filimu wamba, filimu yolimba (filimu wandiweyani), filimu ya ceramic, wosanjikiza wosinthika, semiconductor chotchinga wosanjikiza, etc. kwa anodizing.

Kugawika kwa Anodizing Njira za Aluminium Products

Njira ya anodizing nthawi zina imagwiritsidwa ntchito povumbula (osakutidwa) aluminiyamu yopangidwa ndi makina kapena zida zopukutidwa ndi mankhwala zomwe zimafunikira chitetezo choletsa dzimbiri.Zovala za anodic zimaphatikizapo chromic acid (CAA), sulfuric acid (SAA), phosphoric acid, ndi boric acid sulfuric acid (BSAA) anodizing process.Njira ya anodizing imaphatikizapo chithandizo cha electrolytic chazitsulo, momwe filimu yokhazikika kapena zokutira zimapangidwira pamwamba pazitsulo.Zovala za Anodic zitha kupangidwa pazitsulo zotayidwa mu ma elekitirodi osiyanasiyana pogwiritsa ntchito ma alternating pano kapena mwachindunji.

Anodizing amatheka ndi kumizidwa zotayidwa mu acidic electrolyte kusamba ndi kudutsa panopa sing'anga.Cathode imayikidwa mkati mwa thanki ya anodizing;Aluminiyamu imagwira ntchito ngati anode, imatulutsa ma ion okosijeni kuchokera mu electrolyte ndikumanga maatomu a aluminiyamu pamwamba pa gawo la anodized.Choncho, anodizing ndi oxidation kwambiri controllable kuti timapitiriza zochitika zachilengedwe.

Anodization zikuphatikizapo Type I, Type II, ndi Type III.Anodizing ndi njira ya electrolytic passivation yomwe imagwiritsidwa ntchito kuonjezera makulidwe a oxide wosanjikiza pamwamba pa zigawo za aluminiyamu.Zigawo za aluminiyamu ndi anodized (motero zimatchedwa "anodizing"), ndipo panopa ikuyenda pakati pawo ndi cathode (nthawi zambiri ndi ndodo ya aluminium) kudzera mu electrolyte yomwe tatchulayi (yomwe imakonda sulfuric acid).Ntchito yayikulu ya anodizing ndikuwonjezera kukana kwa dzimbiri, kukana kuvala, kumamatira utoto ndi zoyambira, etc.

PIC ndi Corlee:Mtundu IIIzigawo za aluminiyamu anodized

Mapangidwe a anode oxide amachokera ku gawo lapansi la aluminiyamu ndipo amapangidwa ndi aluminium oxide.Mtundu uwu wa aluminiyamu sugwiritsidwa ntchito pamwamba monga utoto kapena zokutira, koma zimagwirizanitsidwa kwathunthu ndi gawo la pansi la aluminiyamu, kotero silidzaphwanyidwa kapena kupukuta.Ili ndi mawonekedwe opangidwa ndi porous kwambiri ndipo imatha kupangidwanso ndikusintha kwachiwiri monga kupaka utoto ndi kusindikiza.
