Mu mafakitale amakono, ukadaulo woyika mafilimu ochepa umagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana kuphatikiza zamagetsi, kuwala, magalimoto, ndi ndege. Kusankha njira yoyenera yoyika vacuum ndikofunikira kwambiri kuti zitsimikizire kuti zinthu zili bwino, kupititsa patsogolo ntchito yopangira, komanso kuwongolera ndalama. Monga njira yapamwamba kwambiri yopangira zinthu pamwamba, kuika vacuum kumaphatikizapo njira zosiyanasiyana zoyika, iliyonse ili ndi zabwino zake komanso malo ogwiritsira ntchito.
Ndiye, kodi mumadziwa bwanji njira yophikira yomwe ikugwirizana ndi zosowa zanu? Bukuli likufotokoza njira zomwe zimagwiritsidwa ntchito kwambiri pophikira vacuum komanso zinthu zofunika kuziganizira posankha njira yophikira.
Njira Zofala Zophikira Vacuum
1. Kutulutsa nthunzi m'thupi (PVD)
PVD imatanthauza gulu la njira zophikira vacuum komwe zinthu zimaphikidwa ndi nthunzi kenako nkuzipinda ngati filimu yopyapyala pamwamba pa substrate. Njira zodziwika bwino za PVD ndi izi:
Kutulutsa kwa Magnetron, Kutulutsa kwa Kutentha, Kutulutsa kwa Electron Beam (E-beam)
PVD imapereka filimu yabwino kwambiri, yolimba kwambiri, yofanana, komanso yolemera kwambiri. Ndi yoyenera mitundu yosiyanasiyana ya zitsulo, zoumba, ndi zitsulo zina.
Mapulogalamu Odziwika:
PVD ndi yabwino kwambiri pa zipangizo zamagetsi, zophimba zokongoletsera, ndi zophimba zolimba, makamaka pamene pakufunika mphamvu yolimba komanso kulimba kwambiri.
2. Kutulutsa nthunzi ya mankhwala (CVD)
CVD ndi njira yomwe mpweya wotentha umagwirira ntchito pafupi kapena pamwamba pa substrate kuti upange filimu yopyapyala yolimba. Imalola kulamulira bwino makulidwe a filimu, kapangidwe kake, ndi kufanana kwake.
Mapulogalamu Odziwika:
CVD imagwiritsidwa ntchito kwambiri mumakampani opanga ma semiconductor, ma solar photovoltaics, ndi ma precision optical coating, komwe mafilimu oyera kwambiri komanso ofanana kwambiri ndi ofunikira.
3. Kutulutsa Nthunzi Yowonjezera Madzi mu Plasma (PECVD)
PECVD ndi mtundu wa CVD womwe umagwiritsa ntchito plasma excitation kuti uwonjezere zochita za mankhwala pa kutentha kochepa, zomwe zimathandiza kuti pakhale kuphimba pa zinthu zomwe zimakhudzidwa ndi kutentha.
Mapulogalamu Odziwika:
PECVD imagwiritsidwa ntchito mu ma solar cell a thin-film, OLED displays, ndi microelectronics, makamaka pa mafilimu ogwiritsira ntchito magetsi.
4. Chophimba cha nthunzi
Kuphimba nthunzi kumaphatikizapo kutenthetsa zinthu zolimba pansi pa vacuum mpaka zitasungunuka kapena kusungunuka, kenako n’kuziyika pa substrate kuti zipange filimu yopyapyala. Njira zodziwika bwino zimaphatikizapo kutentha ndi kutentha ndi kuwala kwa ma elekitironi.
Njira imeneyi ndi yosavuta, yotsika mtengo, komanso yoyenera kugwiritsidwa ntchito komwe sikofunikira kuwongolera kwambiri mawonekedwe a filimu.
Mapulogalamu Odziwika:
Kutulutsa nthunzi kumagwiritsidwa ntchito kwambiri popanga zokutira zowunikira, zokongoletsera, ndi zoteteza, makamaka m'malo otsika mtengo komanso akuluakulu.
5. Kutaya Magazi
Kutulutsa madzi kumaphatikizapo kuponya ma ayoni amphamvu kwambiri pa chinthu chomwe mukufuna, zomwe zimapangitsa kuti maatomu atuluke ndikuyikidwa pa substrate. Kumapereka mafilimu okhala ndi kuchuluka kwakukulu, okhala ndi kuphimba bwino masitepe pa geometries zovuta za substrate.
Mapulogalamu Odziwika:
Kupopera kwa sputtering kumagwiritsidwa ntchito kwambiri mu ma semiconductors, mafilimu optical, maginito media, ndi zophimba zolimba, makamaka komwe kufanana kwa filimu ndi kumamatira kwambiri ndikofunikira.
Zinthu Zofunika Kwambiri Posankha Njira Yophikira Vacuum
1. Zinthu Zofunika Pansi ndi Jiyomethri
Kapangidwe ndi mawonekedwe a gawo lapansi (monga chitsulo, galasi, ceramic, pulasitiki) zimakhudza kwambiri kusankha njira. Pa ma geometries ovuta a 3D, CVD ndi sputtering zimapereka kufanana kwabwino komanso kufanana. Pa magawo osalala kapena osavuta, evaporation ndi PVD zingakhale zokwanira.
2. Kapangidwe ka Filimu Komwe Amafunidwa
Makhalidwe a ntchito ya chophimba ndi chinthu chachikulu chomwe chimapangitsa kuti chikhale cholimba. Mwachitsanzo:
Pakulimba kwambiri komanso kusawonongeka, magnetron sputtering (PVD) ndi yabwino kwambiri.
Pa mafilimu opangidwa ndi kutentha kochepa komanso oyeretsedwa kwambiri, PECVD ndi yabwino kwambiri.
Pa zophimba zokongola kapena zokongoletsera, kutenthetsa ndi njira yotsika mtengo kwambiri.
3. Kugwira Ntchito Moyenera ndi Mtengo
Njira iliyonse imasiyana malinga ndi ndalama zomwe zayikidwa komanso mtengo wogwirira ntchito:
Kutulutsa nthunzi kumakhala kotsika mtengo ndipo n'koyenera kupanga zinthu zambiri, koma popanda kulamulira bwino filimu.
PVD ndi CVD zimapereka filimu yabwino kwambiri koma zimafuna ndalama zambiri komanso zovuta zaukadaulo.
Opanga zisankho ayenera kulinganiza mtengo ndi magwiridwe antchito malinga ndi zofunikira za malonda.
4. Zofunikira pa Kukhuthala kwa Filimu ndi Kufanana
Ngati ntchito yanu ikufuna kuwongolera bwino makulidwe a filimu ndi kufanana kwake, njira za PVD ndi CVD ndizoyenera kwambiri. Kumbali ina, kupopera ndi kutulutsa madzi pang'ono kungakhale kovomerezeka pa zokutira zomwe sizili ndi makulidwe ambiri.
5. Zofunika Kuganizira pa Zachilengedwe ndi Chitetezo
Njira zina zotulutsira mpweya—makamaka CVD ndi PECVD—zimakhudza mpweya woipa kapena woopsa. Kuwongolera bwino chitetezo ndi njira zopumira mpweya ndizofunikira. Mosiyana ndi zimenezi, PVD nthawi zambiri imakhala yoyera komanso yosawononga chilengedwe, zomwe zimapangitsa kuti ikhale chisankho chotetezeka pa ntchito zambiri.
Kusankha njira yoyenera yophikira vacuum ndikofunikira kuti filimu igwire bwino ntchito, kukonza bwino ntchito yopangira, komanso kusamalira ndalama. Mukamvetsetsa ubwino, zofooka, ndi momwe ntchito iliyonse imagwiritsidwira ntchito, mutha kupanga zisankho zolondola zogwirizana ndi zosowa zanu.
Kaya cholinga chanu ndi kuwonjezera kulimba kwa pamwamba, kulimbitsa kukana kutopa, kukonza magwiridwe antchito a kuwala, kapena kuchepetsa ndalama zopangira, kusankha ukadaulo woyenera wokutira kudzakhudza mwachindunji mtundu wa chinthu chanu komanso mpikisano pamsika.
—Nkhaniyi yafalitsidwa ndi zida zophikira zotsukira wopanga Zhenhua Vacuum
