Pamene kupanga zinthu padziko lonse lapansi kukufulumizitsa kusintha kwake kupita ku kupanga zinthu zopanda mpweya woipa, zoteteza chilengedwe, komanso zogwira ntchito bwino, Vacuum Coating Technology yaonekera ngati njira yofunika kwambiri yomaliza pamwamba pa zinthu zobiriwira. Podziwika ndi kugwiritsa ntchito zinthu zambiri, kusakhala ndi madzi otayira, komanso kugwiritsa ntchito mphamvu zochepa, vacuum clothing imadziwika ngati njira ina yokhazikika m'malo mwa njira zachikhalidwe zonyowa monga kujambula ndi electroplating. Sikuti imangokwaniritsa zofunikira zogwirira ntchito komanso zokongoletsera komanso imaperekanso zabwino zambiri zachilengedwe.
Nambala 1 Njira Yoyera Mkati
Chophimba cha vacuumamatanthauza njira zochotsera nthunzi m'thupi (PVD) kapena njira zochotsera nthunzi m'thupi (CVD), komwe zitsulo kapena zinthu zogwirira ntchito zimayikidwa pa substrate mu mawonekedwe a maatomu kapena mamolekyu pansi pa mikhalidwe yotupa kwambiri, ndikupanga wosanjikiza woonda. Njirayi ndi yoyera chifukwa chosowa mankhwala amadzimadzi, ma electrolyte, ndi njira zochiritsira kutentha. Zinthu zazikulu zachilengedwe ndi izi:
Palibe kutayira madzi otayira: Mosiyana ndi kupaka utoto pogwiritsa ntchito electroplating kapena spray, vacuum clothing sikutanthauza kusamba ndi asidi/alkaline baths, ma electrolytes, kapena kutsuka ndi madzi, motero kupewa kutayira zitsulo zolemera, COD, ndi ma surfactants.
Palibe mpweya wa VOC: Popeza zinthu zophimba zimasamutsidwa kudzera mu kutentha kwa mpweya, kutulutsa madzi, kapena kuphulika kwa ma ion popanda zinthu zachilengedwe zosungunulira, palibe Volatile Organic Compounds (VOCs) zomwe zimatulutsidwa, zomwe zimachotsa gwero lalikulu la kuipitsa mpweya m'mizere yachikhalidwe yophimba.
Zinyalala zochepa zolimba: Zotsalira zokha zolimba zomwe zimapangidwa ndi zinthu zochepa zomwe zingabwezeretsedwe komanso fumbi loyeretsa louma, popanda kupanga matope kapena zinyalala zopopera kwambiri.
Nambala 2 Kugwiritsa Ntchito Zinthu Zambiri, Kutaya Zinthu Zochepa
Mu njira zodziwika bwino za PVD monga Magnetron Sputtering ndi Thermal Evaporation, zinthu zimayikidwa mu mawonekedwe a mpweya, zomwe zimapangitsa kuti zikhale bwino kwambiri kuposa 30% mpaka 70% - zomwe zimakhala zapamwamba kwambiri kuposa 10% mpaka 30% zomwe zimagwiritsidwa ntchito popopera. Kukonzanso bwino mawonekedwe a cholinga, kuchuluka kwa mphamvu, ndi njira yoyika zinthu kungathandize kuti zinthu zizigwira bwino ntchito komanso kuchepetsa kutayika kwa zinthu zopangira.
Pazinthu zamtengo wapatali komanso zosowa (monga Au, Pt, ITO, Cr), chophimba cha vacuum chimalola kuyika bwino zinthu komanso kubwezeretsanso zinthu moyenera, zomwe zimapereka phindu lachuma komanso chilengedwe m'mafakitale a zamagetsi, optics, ndi semiconductor.
Nambala 3 Njira Yokhazikika M'malo mwa Kupaka Ma Electroplating ndi Kupaka Utoto
Kupaka vacuum tsopano kumalola mitundu yosiyanasiyana ya zokongoletsera, kuphatikizapo zitsulo, zonga ceramic, zonyezimira, kapena zosaoneka bwino. Kwakhala njira yabwino yosinthira mankhwala owopsa pa malo okhala ndi chromium, nickel, ndi zinthu zina zoopsa. Imagwiritsidwa ntchito pa pulasitiki, ceramic, ndi zitsulo, imathandizira zophimba zokongoletsera zotetezeka komanso zobiriwira.
Mwachitsanzo, kusintha kwa PVD chrome ndi njira yodziwika bwino ku Europe, US, ndi Japan. Pakadali pano, zophimba zodzaza ndi vacuum zomwe zimachotsa kufunikira kopaka utoto wopopera zagwiritsidwa ntchito mu magetsi a magalimoto ndi zinthu zamkati—kupangitsa kuti pakhale kusintha kuchoka pa “kusawononga” kupita ku “kusintha kwa kuipitsa.”
Nambala 4 Imagwirizana ndi Kupanga Mpweya Wochepa ndi Kuchepetsa Kutsika kwa Mpweya
Popeza kugogomezera kwambiri kusagwirizana ndi mpweya wa carbon ndi kutulutsa mpweya m'thupi, zipangizo zopangira vacuum clothing zikupangidwa kuti zigwiritse ntchito mphamvu moyenera—zili ndi kutentha kolamulidwa, kupopera vacuum m'malo osiyanasiyana, ndi makina obwezeretsa mphamvu. Kupita patsogolo kosalekeza pakugwiritsa ntchito mphamvu ya plasma ndi kukonza magetsi kumathandizanso kuchepetsa mpweya wa carbon.
Kuphatikiza apo, mafilimu ena osungidwa mu vacuum amathandizira mwachindunji kusunga mphamvu pansi pa madzi. Ntchito monga magalasi a Low-E, zowunikira zowunikira, ndi zokutira zoteteza kutentha za infrared zimathandiza kukonza mphamvu moyenera mu unyolo wonse wamtengo wapatali, ndikulimbitsa ntchito yawo popanga zinthu zokhazikika.
Kupaka vacuum sikungokhala njira yopangira zinthu zapamwamba kwambiri—ndi ukadaulo wofunikira kwambiri mtsogolo popanga zinthu zobiriwira. Mphamvu zake za kusatulutsa mpweya woipa, kugwira ntchito bwino kwambiri, komanso kuthekera kosintha njira zimapatsa mwayi woti zinthuzo zigwiritsidwe ntchito kwa nthawi yayitali m'nthawi yovuta kwambiri yokhudza kukhwimitsa malamulo okhudza chilengedwe.
