Kayendedwe ka ntchito ya ma optical coaters nthawi zambiri kamakhala ndi masitepe akuluakulu otsatirawa: kukonza zinthu zisanakonzedwe, kuphimba, kuyang'anira ndi kusintha filimu, kuziziritsa ndi kuchotsa. Njira yeniyeniyo ingasiyane kutengera mtundu wa zida (monga evaporation coater, sputtering coater, ndi zina zotero) ndi njira yophimba (monga single layer film, multilayer film, ndi zina zotero), koma kawirikawiri, njira yophimba zinthu zowala imakhala motere:
Choyamba, gawo lokonzekera
Kuyeretsa ndi kukonza zida zowunikira:
Musanaphike, zinthu zowunikira (monga magalasi, zosefera, magalasi owunikira, ndi zina zotero) ziyenera kutsukidwa bwino. Gawo ili ndiye maziko otsimikizira mtundu wa chophimbacho. Njira zoyeretsera zomwe zimagwiritsidwa ntchito kwambiri zimaphatikizapo kuyeretsa ndi ultrasound, pickling, kuyeretsa ndi nthunzi ndi zina zotero.
Zinthu zoyera zowunikira nthawi zambiri zimayikidwa pa chipangizo chozungulira kapena makina olumikizira makina kuti zitsimikizire kuti zitha kukhalabe zokhazikika panthawi yophimba.
Kukonza chipinda chotsukira mpweya musanagwiritse ntchito:
Musanayike chinthu chowunikira mu makina ophimba, chipinda chophimba chiyenera kupopedwa mpaka pamlingo winawake wa vacuum. Malo ophimba amatha kuchotsa bwino zinyalala, mpweya ndi nthunzi ya madzi mumlengalenga, kuziletsa kuti zisagwirizane ndi zinthu zophimba, ndikuwonetsetsa kuti filimuyo ndi yoyera komanso yabwino.
Kawirikawiri, chipinda chophikiracho chiyenera kukhala ndi vacuum yambiri (10⁻⁵ mpaka 10⁻⁶ Pa) kapena vacuum yapakati (10⁻³ mpaka 10⁻⁴ Pa).
Chachiwiri, njira yophikira
Gwero loyambira la zokutira:
Gwero la chophimba nthawi zambiri limakhala gwero la nthunzi kapena gwero la kutulutsa madzi. Magwero osiyanasiyana a chophimba adzasankhidwa malinga ndi njira yophikira ndi zinthu.
Gwero la nthunzi: Chophimbacho chimatenthedwa kuti chikhale chonyowa pogwiritsa ntchito chipangizo chotenthetsera, monga evaporator ya electron beam kapena evaporator yotenthetsera yokana, kotero kuti mamolekyu ake kapena maatomu ake amasanduka nthunzi ndipo amaikidwa pamwamba pa chinthu chowunikira mu vacuum.
Gwero la kutulutsa mpweya: Pogwiritsa ntchito mphamvu yamagetsi yapamwamba, chinthucho chimagundana ndi ma ayoni, kutulutsa maatomu kapena mamolekyu a chinthucho, omwe amaikidwa pamwamba pa chinthucho kuti apange filimu.
Kuyika zinthu mufilimu:
Mu malo opanda mpweya, zinthu zophimbidwazo zimasanduka nthunzi kapena zimatuluka kuchokera ku gwero (monga gwero la nthunzi kapena cholinga) ndipo pang'onopang'ono zimagwera pamwamba pa chinthu chowunikira.
Kuchuluka kwa kuyika ndi makulidwe a filimu ziyenera kulamulidwa bwino kuti zitsimikizire kuti gawo la filimuyo ndi lofanana, lopitirira, komanso likukwaniritsa zofunikira pa kapangidwe kake. Magawo panthawi yoyika (monga mphamvu yamagetsi, kuyenda kwa mpweya, kutentha, ndi zina zotero) adzakhudza mwachindunji mtundu wa filimuyo.
Kuwunika mafilimu ndi kuwongolera makulidwe:
Mu ndondomeko yophimba, makulidwe ndi mtundu wa filimu nthawi zambiri zimawunikidwa nthawi yeniyeni, ndipo zida zowunikira zomwe zimagwiritsidwa ntchito kwambiri ndi quartz crystal microbalance (QCM) ** ndi masensa ena, omwe amatha kuzindikira molondola kuchuluka kwa malo ndi makulidwe a filimuyo.
Kutengera ndi deta yowunikirayi, makinawa amatha kusintha zokha magawo monga mphamvu ya gwero lophimba, kuchuluka kwa mpweya wotuluka kapena liwiro lozungulira la gawolo kuti asunge kufanana ndi kufanana kwa gawo la filimuyo.
Filimu yokhala ndi zigawo zambiri (ngati pakufunika):
Pazigawo zowala zomwe zimafuna kapangidwe ka multilayer, njira yophikira nthawi zambiri imachitika mu gawo ndi gawo. Pambuyo poika gawo lililonse, dongosololi lidzayang'ana ndikusintha makulidwe a filimu mobwerezabwereza kuti zitsimikizire kuti mtundu wa gawo lililonse la filimuyo ukukwaniritsa zofunikira pa kapangidwe kake.
Njirayi imafuna kuwongolera bwino makulidwe ndi mtundu wa zinthu za gawo lililonse kuti zitsimikizire kuti gawo lililonse likhoza kugwira ntchito monga kuwunikira, kutumiza kapena kusokoneza mu utali winawake wa wavelength.
Chachitatu, ziziziritseni ndikuchotsa
CD:
Pambuyo poti chophimbacho chatha, ma optics ndi makina ophimba amafunika kuziziritsidwa. Popeza zida ndi zida zina zimatha kutentha panthawi yophimba, ziyenera kuziziritsidwa kutentha kwa chipinda ndi makina oziziritsira, monga madzi ozizira kapena mpweya woyenda, kuti apewe kuwonongeka kwa kutentha.
Mu njira zina zophikira kutentha kwambiri, kuzizira sikuti kumateteza chinthu chowala chokha, komanso kumathandiza kuti filimuyo ikhale yolimba komanso yolimba.
Chotsani chinthu chowunikira:
Pambuyo poti kuziziritsa kwatha, chinthu chowunikira chingachotsedwe pamakina ophikira.
Musanachotse, ndikofunikira kuyang'ana momwe chophimbacho chikugwirira ntchito, kuphatikizapo kufanana kwa gawo la filimu, makulidwe a filimu, kumatira, ndi zina zotero, kuti muwonetsetse kuti mtundu wa chophimbacho ukukwaniritsa zofunikira.
4. Kukonza pambuyo (ngati mukufuna)
Kulimbitsa filimu:
Nthawi zina filimu yokutidwa imafunika kulimba kuti isamakandane komanso kuti isamakhale yolimba. Izi nthawi zambiri zimachitika pogwiritsa ntchito njira monga kutentha kapena kuwala kwa ultraviolet.
Kuyeretsa filimu:
Pofuna kuchotsa zodetsa, mafuta kapena zonyansa zina pamwamba pa filimuyi, pangafunike kuyeretsa pang'ono, monga kuyeretsa, kugwiritsa ntchito ultrasound, ndi zina zotero.
5. Kuyang'anira ndi kuyesa khalidwe
Mayeso a magwiridwe antchito a kuwala: Pambuyo poti chophimbacho chatha, mayeso angapo a magwiridwe antchito amachitika pa gawo la kuwala, kuphatikizapo kutumiza kuwala, kuwunikira, kufanana kwa filimu, ndi zina zotero, kuti zitsimikizire kuti zikukwaniritsa zofunikira zaukadaulo.
Kuyesa kumatira: Pogwiritsa ntchito tepi kapena kuyesa kukanda, onani ngati kumatirana pakati pa filimu ndi substrate kuli kolimba.
Kuyesa kukhazikika kwa chilengedwe: Nthawi zina ndikofunikira kuchita mayeso okhazikika pamikhalidwe yachilengedwe monga kutentha, chinyezi, ndi kuwala kwa ultraviolet kuti zitsimikizire kudalirika kwa gawo lophimba pakugwiritsa ntchito moyenera.
