Monga nsalu yotchinga yokhala ndi zaka pafupifupi 70 yogwira ntchito bwino kunja, gulu la aluminiyamu lodzozedwa layambanso kuonekera bwino m'mapulojekiti omanga m'nyumba m'zaka zaposachedwa, pakati pa omwe otchuka kwambiri ndi Shanghai Planetarium ndi TAG Art Museum. Magulu a aluminiyamu odzozedwa amagwiritsidwa ntchito mbali zonse za Shanghai Planetarium, ndipo magulu odulira ooneka ngati diamondi amagwiritsidwa ntchito mbali zosiyanasiyana.
Ndi kutuluka kwa dzuwa ndi kulowa kwa dzuwa kwa chiwonetsero cha kuwala cha usiku, wowonera amatha kuwona kuwala ndi mthunzi wosiyanasiyana kuchokera ku ngodya iliyonse.
Ndipo ntchito yatsopano ya Jean Nouvel, TAG Art Museum.Malo owonetsera zithunzi a nyumbayi amakongoletsedwa ndi mafani 127 a aluminiyamu opangidwa ndi magetsi ophikira dzuwa, omwe amapatsa nyumbayo kuwala kwachitsulo chifukwa cha kuwala kwa dzuwa.
Kuphatikiza apo, m'zaka zaposachedwapa, ntchito zambiri zapakhomo za aluminiyamu zogwiritsidwa ntchito ndi anodized zilinso zambiri, monga:Nyumba zazikulu zodziwika bwino: Wuyuanhe Culture and Sports Center, Henan Science and Technology Museum, Jiaxing Station, Linping Sports Park Tennis Hall, Haixin Bridge, JW Marriott Marquis Hotel, ndi zina zotero.
Ndiye kodi pali kusiyana kotani pakati pa gulu la aluminiyamu lopangidwa ndi anodized ndi gulu la aluminiyamu la fluorocarbon lomwe limagwiritsidwa ntchito kwambiri mumakampani?Nkhaniyi ikufotokozedwa m'mbali zinayi: njira yochizira pamwamba, kuuma kwa pamwamba, kuyeretsa kosavuta, ndi kulimba.

Ukadaulo wochizira pamwamba
Yokonzedwagulu la aluminiyamu
Choyamba, kodi njira yopangira anodizing ndi chiyani?Anodizing ndi njira yamagetsi yomwe imapanga wosanjikiza wokhuthala pa aluminiyamu.
Al2O3 ndi kapangidwe ka mankhwala komwe sikasintha, kali ndi kuuma kwakukulu pakati pa ma oxide, komanso kamalimbana ndi nyengo kwambiri. Ngakhale gawo la oxide litakumana ndi moto, aluminiyamu imasungunuka koma gawo la oxide silisintha. Sikokomeza kunena kuti alumina wodzozedwa ndi Rolls Royce wa gulu la aluminiyamu. Ndipotu, sikokomeza kufunsa kuti ndi njira iti yochizira pamwamba yomwe ingapeze mawonekedwe okhuthala chonchi?
Gulu la aluminiyamu la kaboni la Fluorine
Chophimba cha aluminiyamu cha fluorocarbon chimapopedwa pamwamba pa aluminiyamu pogwiritsa ntchito njira yoyeretsera utoto. Ngakhale kuti chophimba cha fluorocarbon chimawonjezedwa ndi utomoni wa fluorine kuti chigwire bwino ntchito, kapangidwe ka polima ka filimu ya utoto kadzapitirizabe kuwunikira ndi kuwala kwa ultraviolet komwe kumasweka, kuphwanyika ndi kuchotsedwa.

Kuuma kwa pamwamba
Kuuma kwa pamwamba pa aluminiyamu oxide panel ndi aluminiyamu yopakidwa utoto kumayesedwa pogwiritsa ntchito mayeso okhwima a pensulo omwe amagwiritsidwa ntchito kwambiri.Titha kupeza kuti kuuma kwa pensulo ndi 9H (pensulo yolimba kwambiri mu labotale), komanso singathe kukanda filimu ya oxide, ndiko kuti, kuuma kwa filimu ya oxide ndi koposa 9H.
Ngati kuuma kwa filimu ya oxide kumayesedwa ndi kuuma kwa Mohs, diamondi yodziwika bwino imakhala ndi kuuma kwa Mohs kwa 10, pomwe zigawo za oxide layer, aluminiyamu oxide ndi safiro, zimakhala ndi kuuma kwa Mohs kwa 9 pambuyo pa diamondi.

Zosavuta kuyeretsa
Khoma lalikulu la aluminiyamu lopangidwa ndi fluorocarbon, lomwe linakhazikitsidwa patangopita miyezi itatu yokha, lidzaonekera ngati likulowa m'malo mwake ndipo kuipitsidwa kwa madzi kudzayamba kuonekera, ndipo fumbi lidzayamba kufalikira kwambiri, ndipo nthawi idzawonjezeka, ndipo zinthu zoipitsa zidzasungunuka n’kusuntha pamwamba pa matope kupita mkati mwa chivindikirocho, zomwe zidzakhudza kwambiri mawonekedwe a khoma la nsaluyo.
Mukayang'aniridwa pogwiritsa ntchito maikulosikopu, utoto wa fluorocarbon umaoneka pa kukula kwa nthawi 500, wofanana ndi kapangidwe ka siponji yokhala ndi mabowo.
Chifukwa cha kuchuluka kwa aluminiyamu yokonzedwa ndi anodized, kapangidwe kake sikanatha kuwoneka mu kukula kwa 500x, kotero kanayenera kukulitsidwa kufika pa 150,000x. Zotsatira zake zinali zodabwitsa. Filimu ya oxide ili ngati kapangidwe kolimba kopanda mpata uliwonse wa linga, yayitali kwambiri pamwamba pa substrate ya aluminiyamu, gulu la aluminiyamu mpaka pamlingo wapamwamba kwambiri wa chithandizo liyenera kukhala Nambala 1!
Chigawo cha oxide cha anodized aluminiyamu chili chofanana ndi chigawo cha corundum ceramic, pamwamba pake sipatenga mphamvu ndipo sichimayamwa fumbi. Kapangidwe kake kolimba kwambiri kamapangitsa kuti zinthu zoipitsa zisamalowe, ndipo zinthu zoipitsa zomwe zimayandama pamwamba pake zimatsukidwa ndi mvula. Malingana ngati kuyeretsa kwachizolowezi, khoma likhoza kukhala latsopano kwa zaka zambiri.
Fluorine carbon aluminiyamu gulu pamwamba pa fluorocarbon polymer resin ❖ kuyanika (komveka bwino ngati pulasitiki), kutenga udindo wa mayamwidwe dothi mosavuta, ndipo pang'onopang'ono zidzauma mu kuwala, kukulitsa dothi, kuletsa dothi mu filimu yokhala ndi matope, kupanga kuipitsidwa kwa madzi oyenda pambuyo pa mvula, ngakhale ndi sopo wamphamvu wa mankhwala, kuchepetsa matope kwakanthawi, komanso kungayambitse khoma la nsalu kukhala lakale kwambiri.

Kulimba
Malinga ndi kusanthula komwe kwatchulidwa pamwambapa, chifukwa cha njira zosiyanasiyana zochizira pamwamba, pali malo amkati mwa filimu ya utoto ya fluorocarbon yomwe ndi yosavuta kuwononga. Pambuyo pa dzimbiri la filamentous, pamwamba pake pamakhala kutsekeka, thovu, ming'alu kapena kusweka. Pambuyo pa kuzizira, pamwamba pa filimu ya utoto pamakhala ufa kuti pakhale ufa wosalala, ndipo kuwala ndi mtundu wake zimachepa kwambiri, zomwe zimapangitsa kuti mawonekedwe a pamwamba awonongeke.
Mosiyana ndi zimenezi, gulu la aluminiyamu lopangidwa ndi anodized, lomwe lakhala likugwira ntchito kwa zaka pafupifupi 70 kunyumba ndi kunja, limatha kupirira kuyeretsa ndi kukonza nyumbayo nthawi zonse.
Kampani ya PPG Industries, yomwe idakhazikitsidwa mu 1883, yagwiritsa ntchito aluminiyamu yosungunuka ngati malo ake oyendetsera ntchito komanso malo ofufuzira ndi chitukuko, yomwe idamangidwa zaka 34 zapitazo popanda kukonza zinthu nthawi zonse.
Mu pulojekiti ya ofesi ya PONT DE SVRES, khoma la nsalu yotchinga ya aluminiyamu yokonzedwa ndi yakale kwambiri, ili ndi zaka 46, ndipo silinakonzedwe nthawi zonse.
Pepala la aluminiyamu lopangidwa ndi anodized lomwe limapirira nyengo yabwino, limatha kusintha kuti ligwirizane ndi malo osiyanasiyana.
