Kodi Vacuum Coating ndi chiyani?
Vacuum coating ndi ukadaulo wapamwamba kwambiri womwe umayika mafilimu owonda kwambiri pamwamba pa ma substrates kudzera munjira zakuthupi kapena zamankhwala m'malo opanda vacuum. Phindu lake lalikulu lagona pakuyera kwambiri, kulondola kwambiri komanso kuteteza chilengedwe, ndipo amagwiritsidwa ntchito kwambiri mu optics, zamagetsi, zida, mphamvu zatsopano ndi zina.
Kodi makina okutira vacuum ayenera kukhala ndi zosefera zolowera?
Choyamba, tiyeni tiphunzire za zoipitsa zomwe zimapezeka mu vacuum coating. Mwachitsanzo, tinthu tating'ono, fumbi, nthunzi yamafuta, nthunzi yamadzi, ndi zina zotero. Zowononga izi zomwe zimalowa m'chipinda chophikira zidzachititsa kuti chiwerengero cha matusidwe chichepe, filimuyo ikhale yosafanana, ndipo ngakhale kuwononga zipangizo.
Zomwe zimakutira vacuum zimafunikira zosefera zolowera
- Pa ❖ kuyanika ndondomeko, chandamale zakuthupi splashes particles.
- Chofunikira cha chiyero cha filimuyi ndipamwamba, makamaka m'minda ya optics ndi semiconductors.
- Pali mpweya wowononga (wopangidwa mosavuta mu reactive sputtering). Pankhaniyi, fyuluta imayikidwa makamaka kuti iteteze pampu ya vacuum.
Zomwe zimakutira vacuum sizifuna zosefera zolowera
- Othandizira ambiri opaka vacuum amagwiritsa ntchito makina otsekemera opanda mafuta (monga pampu ya molekyulu + ion pump), komanso malo ogwirira ntchito ndi oyera. Choncho, palibe chifukwa cha zosefera zolowera, kapena zosefera zotulutsa.
- Palinso zochitika zina zomwe zosefera zolowera sizifunikira, ndiye kuti, kufunikira kwa chiyero cha filimuyo sipamwamba, monga zokutira zina zokongoletsa.
Zina zokhudzana ndi pompu yotulutsa mafuta
- Ngati pampu yamafuta kapena pampu yamafuta ikugwiritsidwa ntchito,zoseferaziyenera kukhazikitsidwa.
- Chosefera cha polima sichimalimbana ndi kutentha kwambiri kwa pampu ya diffusion
- Mukamagwiritsa ntchito pampu yotulutsa mafuta, mafuta a pampu amatha kubwereranso ndikuwononga chipinda chophikira. Chifukwa chake, pamafunika msampha wozizira kapena mafuta kuti mupewe ngozi.
Pomaliza, ngati zingalowe ❖ kuyanika dongosolo ayenerazosefera zolowerazimadalira zofuna za ndondomeko, mapangidwe a dongosolo ndi chiopsezo choipitsidwa.
