Vacuum metalizing pulasitiki ndi njira yomwe imakulolani kuti mupange chitsulo chosanjikiza pagawo laling'ono, nthawi zambiri lazinthu zina. Zomwe zimatchedwanso "vacuum deposition", zimaphatikizanso kutenthetsa zitsulo zokutira mpaka zitasungunuka m'chipinda chochotsera vacuum.

Kupanda kukanikiza m'chipindachi kumapangitsa kuwira kwachitsulo pansi. Izi zimathandiza kuti nthunzi yachitsulo isungunuke ndikupanga wosanjikiza pamwamba pa gawo lapansi lomwe mwasankha. Mwachitsanzo, makampani a semiconductor amagwiritsa ntchito vacuum deposition kuyika zolumikizira zamkuwa pa silicon.

Njirayi ingagwiritse ntchito njira zosiyanasiyana zotenthetsera, kuphatikizapo matabwa a plasma, kutentha kwa mphamvu, ndi ma elekitironi. Chotsatira chake ndi chitsulo chosanjikiza chomwe chimatha kukhala mu makulidwe kuchokera ku atomu imodzi kupita ku mamilimita angapo.

The Best Metal

Poyerekeza ndi aluminiyamu, mkuwa ndi siliva zimakhala ndi mphamvu zamagetsi zamagetsi, koma mkuwa umakhudzidwa ndi okosijeni ndi dzimbiri, pamene siliva ndi yokwera mtengo kwambiri. Chifukwa chotsika mtengo komanso zinthu zowunikira bwino, zitsulo zabwino kwambiri zopangira vacuum metallization ndi aluminiyamu.

1) Aluminiyamu: Pa zokutira zowunikira, zinthu zomwe zimagwiritsidwa ntchito kwambiri ndi aluminiyamu, zomwe zimatha kutulutsa 90%. Zowunikira zamafakitale, zamalonda ndi zamagalimoto zonse zimagwiritsa ntchito aluminiyamu.

2) Mkuwa: Chifukwa cha zabwino zake zopangira, nthawi zambiri amagwiritsidwa ntchito ngati zokutira zotchinga. Komabe, chifukwa imatha kuchita dzimbiri, imayenera kuphimbidwa ndi oxide wosanjikiza kapena chitsulo china (monga faifi tambala-chromium kapena chitsulo chosapanga dzimbiri) kuti isasinthe mtundu kapena makutidwe ndi okosijeni, kotero zokutirazi zimakhalanso zokhuthala, nthawi 10 zokhuthala kuposa mitundu ina yazitsulo.

3) Njira: Muzitsulo za vacuum, zinthuzo zimatenthedwa mpaka zinthuzo zitasungunuka m'chipinda chopanda mpweya. Choyamba, yang'anani njira ziwiri za vacuum metallization.

Metallization njira

Pali mitundu iwiri ikuluikulu ya njira metallization pansipa.

1. Kuyika kwa nthunzi wakuthupi (Kutentha kwa kutentha)

Kupaka kwa vacuum evaporation kapena zokutira za vacuum kumatenthetsa zokutira pamalo opaka vacuum ndikupangitsa kuti zisanyuke pakanthawi kochepa. Mamolekyu osungunula azinthu zokutira amayikidwa pamwamba pa pulasitiki kuti apange chosanjikiza, chomwe chimagwiritsidwa ntchito kusungunula zitsulo zotsika zosungunuka monga aluminiyamu.

Njirayi ndi yosavuta komanso yabwino, yosavuta kugwiritsa ntchito, yofulumira komanso yothandiza kupanga filimu, ndipo ndiyo njira yamakono yomwe imagwiritsidwa ntchito kwambiri pokonzekera filimu yopyapyala.

2. Chemical vapor deposition (Sputtering)

Gasi wolowera amadzadzidwa mu vacuum ndipo mphamvu yamphamvu-yamphamvu kwambiri imawonjezedwa pakati pa gawo lapansi la pulasitiki ndi chitsulo chomwe chimalunjika. Ma elekitironi opangidwa ndi kutulutsa kowala amasangalatsa mpweya wa inert ndikupanga madzi a m'magazi, omwe amachotsa maatomu a chitsulo chachitsulo ndikuwayika pagawo lapulasitiki. Kumamatira kwa filimu yokutira pamwamba pa pulasitiki ndikwabwino kuposa kuphimba kwa evaporation, ndipo filimuyo ndi wandiweyani komanso yunifolomu.

Ntchito Zathu

Chiyambireni kukhazikitsidwa kwathu mu 2004, timadzipereka nthawi zonse kupanga tungsten apamwamba kwambiri ndi zinthu za molybdenum. Tsopano maukonde athu kunja malonda kufalikira mu USA, UK, Germany, India, Germany, Brazil, , Poland, CZ, Slovenia, Singapore ndi etc.

Momwe mungayikitsire oda yanu

Titumizireni mndandanda wamaoda anu (zitsanzo / kuchuluka / zojambula)

tidzakutumizirani PROFORMA INVOICE (PI) ndi mtengo wotumizira komanso zambiri za Malipiro kuti mutsimikizire.

Mumakonza zolipirira mutatsimikizira invoice ya proforma, tidzakonza zopanga mutalandira chidziwitso chanu.

Tsiku loti liperekedwe limadalira zosowa zanu zenizeni

Tidzakonza zobweretsera ndalama zanu zikafika ndipo katundu wakonzeka, ndipo nthawi yomweyo tidzakuuzani nambala yotsatirira katunduyo kuti mudziwe momwe katundu wanu alili ndi nambala iyi kuchokera patsamba la otumiza.

Mudzalandira oda yanu mkati mwa masiku 5-7 katundu atatumizidwa ndi Express Delivery.
