Kusintha komaliza: 09/02, nthawi yowerenga: 7mins

Zigawo za aluminium anodized ndi mitundu yosiyanasiyana

Chifukwa cha kulemera kwawo komanso mphamvu zawo zazikulu,Aluminiyamu ndi mitundu yake yosiyanasiyana ya aloyizida zomangira zimagwiritsidwa ntchito pafupipafupi m'mafakitale osiyanasiyana, kuphatikiza zamankhwala, zamagalimoto, ndi zakuthambo.Zilibe kanthu kuti ndi njira iti yopangira yomwe imagwiritsidwa ntchito popanga magawowa.Kumaliza pamwamban'kofunika kumapangitsanso mbali zimenezi 'makina katundu ndi kukongola zokongoletsa.

Chifukwa mitundu yosiyanasiyana imatha kuphimbidwa pamtundaanodizing, ndi njira yotchuka kwambiri yomaliza pamwamba yomwe imagwiritsidwa ntchito popanga padziko lonse lapansi.Zigawo za aluminiyamu zimapangidwa kuti zikhale zolimba komanso zotsutsa kwambiri kuti ziwonetsedwe ndi chilengedwe, chifukwa cha mtundu wa anodizing.Kuphatikiza apo, kuthekera kokana abrasion kumatha kupezeka ndi anodizing mtundu.Nkhaniyi ifotokoza mwachidulenjira ya Aluminium anodizing, njira zosiyanasiyana zopangira utoto, kufananiza mitundu, ndi njira zina zofananira.

Njira ya Aluminium Anodizing

Kuyeretsa zigawo zopangidwa ndi sitepe yoyamba mu anodizing aluminium, ndipo pa-engraving alkaline ndiye njira yabwino yoyeretsera ntchitoyo.Mafuta onse owala ndi zinthu zina zomwe zingasokoneze anodizing zimachotsedwa panthawi yoyeretsayi.Kuyika kwa alkaline kuyenera kuchitika potsatira kuyeretsa kuti muchotse ma oxide achilengedwe aliwonse otsala pamwamba.Njira yabwino kwambiri ndi sodium hydroxides.

Chotsatira ndikutulutsa zida zotsukidwa ndi zokhazikika za aluminiyamu mu njira ya asidi ya nitric kuti ikhale yosalala ndikukonzekera kuti ikhale ya anodizing.

Magawo osiyanasiyana amtundu wa aluminium anodized

Pomaliza, zigawo za Aluminiyamu zimamizidwa mu electrolyte ya sulfuric acid kuti ikhale ndi anodizing.Cathode ili kunja kwa thanki ya electrolyte.Zigawo za aluminiyumu zomwe zimafunika kuzikuta zimakhala ngati anode.Ndiye magetsi amagwiritsidwa ntchito pa electrode ("+" terminal ku anode ndi "-" terminal to Cathode).Tsopano, mphamvu yamagetsi imadutsa mu njira ya electrolytic ndikutulutsa ma oxide ions, omwe amapita ku gawo lapansi la aluminiyamu kuti apange wosanjikiza wophatikizika wa oxide pamwamba.

Mitundu pazigawo za Aluminium Anodized

Nthawi zambiri, zigawo za aluminiyamu za Anodized zimapakidwa utoto pogwiritsa ntchito njira zinayi izi: utoto wosokoneza, utoto wa utoto, utoto wa ma elekitirodi, ndi mitundu yonse.Tiyeni tione bwinobwino aliyense wa iwo tsopano.

Electro coloring

Mitundu yosiyanasiyana imapezeka mosavuta mu anodized aluminiyamu mbali pamwamba ndielectrolytic coloration.Electrolytic coloring imagwiritsa ntchito mchere wachitsulo wosiyanasiyana monga wopangira utoto, pomwe ayoni achitsulo amchere wogwiritsidwa ntchito amayikidwa mu pores za ma aluminiyamu anodized.Choncho, mtundu umadalira zitsulo zomwe zimagwiritsidwa ntchito mumchere.

Electro coloring process

Monga gawo la ndondomeko electrolysis, ndi anodized pamwamba kumizidwa mu anaikira mayankho a zitsulo mchere mpaka pigment okwanira precipitated kulenga mtundu ankafuna.Chifukwa chake, mtunduwo umadalira chitsulo chomwe chimagwiritsidwa ntchito mumchere, ndipo kuchuluka kwa utoto kumatengera nthawi ya chithandizo (masekondi 30 mpaka 20).

Mchere wachitsulo wamba ndi mitundu yomwe imagwiritsidwa ntchito mu utoto wa aluminium anodized 

Kupaka utoto

Njira ina yopangira mtundu wa anodized aluminiyamu ndi utoto wa utoto.Kuchita zimenezi kumafuna kungoviika zinthuzo kuti zipake utoto mu thanki yomwe ili ndi mankhwala opangira utoto.Kuchuluka kwa mtundu munjira iyi kumadalira mitundu yosiyanasiyana monga kuchuluka kwa utoto, nthawi yamankhwala, ndi kutentha.

Zofotokozera za utoto wa utoto:

Malangizo opangira utoto wabwino kwambiri

·        Kuyeretsa ma aluminiyamu a anodized ndikofunikira chifukwa ma acid omwe amakhala pamwamba amatha kusokoneza kufa.Nthawi zina, kupezeka kwa asidi kumalepheretsa kupaka utoto kwa aluminiyamu.Chifukwa chake, musanayambe kusamba kwa utoto, gwiritsani ntchito sodium bicarbonate kuti muwononge.

·        Masitepe a anodizing ndi kusamba kwa utoto ayenera kumalizidwa nthawi imodzi, mbali zake zimayikidwa mu thanki lopaka utoto zikangochotsedwa mu thanki ya anodizing.

·        Kuonjezera apo, sungani asidi kapena kuipitsidwa kulikonse kutali ndi thanki ya utoto.

Kuphatikiza mitundu

Njira zopangira utoto zimaphatikiza njira ziwiri zosiyana.Choyamba, zigawo za aluminiyamu zimasinthidwa ndi anodized, ndipo zigawo za anodized zimakhala zofiira ndi ma alloys.Choncho, ntchito ya alloy yeniyeni mu ndondomekoyi ndi momwe mtundu umapangidwira.Kutengera kapangidwe ka zigawo za aluminiyamu komanso momwe amagwirira ntchito, mitundu yamitundu imatha kuchokera ku mkuwa wagolide kupita kumkuwa wakuya mpaka wakuda.

Kusokoneza utoto

Njirayi imaphatikizapo kukulitsa kapangidwe ka pore ndikuyika chitsulo choyenera kutengera mitundu yofunikira pamtunda kuti apeze utoto wamitundu.Monga mungapeze mtundu wa buluu-imvi ngati mutayika faifi tambala.Kwenikweni, mitundu yosokoneza imapangidwa pamene kuwala kugunda malo a aluminiyamu ya anodized ndikusinthidwa, kuwonekera, kapena kuyamwa.

Kusindikiza-Njira

Kusindikiza ndondomeko

Cholinga chachikulu cha ndondomeko yosindikiza ndikuletsa mamolekyu osafunika kuti asalowe mu pores.Chifukwa mafuta kapena mamolekyu ena osavomerezeka nthawi zina amasungidwa mu pores, zomwe zimapangitsa kuti pakhale dzimbiri.Zida zina zomata zodziwika bwino ndi nickel acetate, potassium dichromate, ndi madzi otentha.

1.          Njira yamadzi otentha

Chitsulo chosapanga dzimbiri kapena zinthu zina za inert nthawi zambiri zimagwiritsidwa ntchito popanga thanki yosindikizira.The wachikuda zotayidwa zigawo zikuluzikulu choyamba kumizidwa m'madzi otentha (200 0F), kumene zotayidwa monohydrate mawonekedwe padziko, pamodzi ndi lolingana kuwonjezeka voliyumu.Zotsatira zake, mamolekyu osafunika amachotsedwa mu pore.

2.           Nickel Fluoride Njira

Njirayi imafewetsa zigawo za aluminiyamu za anodized.Mwanjira iyi, failo wa fluoride umayambitsidwa ku anodized aluminium.Fluoride ion tsopano imapita ku pores, komwe nickel ion imalowa pamwamba ndikupanga nickel hydroxide pophatikizana ndi mamolekyu amadzi, ndikutsekereza pores.

3.          Njira ya Potaziyamu Dichromate

Njirayi imagwiritsa ntchito njira ya potassium dichromate (5 % w/V) kusindikiza zigawo za aluminiyamu za anodized.Choyamba, zigawozo zimamizidwa kwa mphindi 15 mu thanki yomwe ili ndi madzi otentha a potaziyamu dichromate.Kenaka, pamwamba pa zigawozo zimatenga ayoni a chromate, ndipo kuyanika kumachitika pamene ma ion awa amakhala ndi madzi.Ngakhale kuti sichitha kuwononga madontho kuposa njira zina zosindikizira, zokutira uku kumaperekabe njira yowongoka yosindikiza.

Kufananiza Mitundu

Mtundu wofananira ukhoza kukhala wosiyana malinga ndi magulu osiyanasiyana;Komabe, Ngati mutsatira ndondomeko yeniyeni ya utoto wa zigawo za aluminiyamu anodized.Pachifukwa ichi, ndondomekoyi ndi zinthu zina monga kalasi ya aluminiyumu yogwiritsidwa ntchito, mtundu wa mapeto, kuchuluka kwa mafelemu, ndi mawonekedwe a crystalline pamwamba pake ayenera kukhala ofanana mofanana pamagulu kuti apeze mtundu wofanana.

Mapeto

Pambuyo kupenda anodizing ndi mtundu wa mbali zotayidwa, n'zoonekeratu kuti phindu zotayidwa anodizing ndi luso implants mitundu yosiyanasiyana pamwamba, amene osati kumawonjezera katundu makina ndi zokongoletsa kukongola komanso kukumana zofuna msika.Kuphatikiza apo, njira yopangira utoto wamagetsi ndiyo njira yabwino kwambiri panjira zinayi zopangira utoto chifukwa imayika mtundu wa electrochemically ndipo imalola kupanga mitundu yambiri yamitundu posankha njira yoyenera yamchere.

Mosakayikira, njira yopangira aluminium anodizing ndizovuta kwambiri chifukwa imaphatikizapo zambiri zamakina, sayansi yazinthu, ndi kupanga uinjiniya.Komabe, sipadzakhala chisokonezo chilichonse mukasankha chathuntchito ya anodizing. Sayansi yathu yakuthupi ndi uinjiniya wamakinaakatswiri adzakupatsirani aluminium anodizing yapamwamba kwambiri, ndipo mutha kusankha mtundu womwe umagwirizana bwino ndi polojekiti yanu.

FAQs

Kodi aluminium anodizing process ndi chiyani?

Ndi mitundu iti yomwe ingabzalidwe pazigawo za aluminiyamu ya anodized?

Palibe yankho lenileni, koma pafupifupi mitundu yonse ingagwiritsidwe ntchito pamwamba ndi njira ya anodizing.

Kodi ndi njira ziti zopangira utoto wa aluminiyamu ya anodized?

Mitundu ya ma elekitirodi, utoto wa utoto, utoto wosokoneza, ndi mtundu wa Integral ndi njira zodziwika kwambiri.

Kodi mtundu wa anodizing pamwamba umazirala pakapita nthawi?

Ayi, ndi yolimba kwambiri.Komabe, sichizimitsidwa pamalo okhazikika mpaka kutsuka kwa acidic kuyikidwa pamwamba.
