Electron Beam Tungsten Filaments
I-E-Beam Tungsten Filaments
I-Tungsten yaziwa ngozinzo lwayo oluhle kakhulu lwe-thermal kunye nendawo ephezulu yokunyibilika, iyenza ibe yinto efanelekileyo kwimicu ye-electron beam. I-Electron beam tungsten filaments inokumelana namaqondo obushushu aphezulu avelisiweyo ngexesha lenkqubo ye-vaporization, iqinisekisa ukusebenza okuthembekileyo, okuqhubekayo ngexesha elide.
Iifilaments ze-electron beam tungsten ziyinxalenye ebalulekileyo kwiinkqubo zokubeka i-vacuum, zisebenzisa amandla e-electron bombardment ukukhupha izinto ezijoliswe kuzo. Le nkqubo yokuguquka komphunga idala ukuhamba kweeathom okanye iimolekyuli ezivumela ukubekwa kweefilim ezibhityileyo ezinokufana okugqwesileyo, ukuxinana, kunye nobunyulu.
Senza i-tungsten filament kuzo zonke iinkqubo ezithandwayo ze-electron beam kwaye sinikezela nge-OEM yesiko le-tungsten filament (JEOL, Leybold, Telemark, Temescal, Thermionic, njl.).

Isicelo
Iifilaments ze-Electron beam tungsten zisetyenziswa kwiintlobo ngeentlobo zamashishini kunye nemimandla, kubandakanya ukwenziwa kwe-semiconductor, i-optics, i-aerospace, kunye nemoto. Zisetyenziselwa ukufaka iifilimu ezicekethekileyo zesinyithi, iioksidi, kunye nezinye izinto kwi-substrates yezicelo ezinje ngeesekethe ezidityanisiweyo, ii-optical coatings, iiseli zelanga, kunye nokugqitywa kokuhombisa.
Yintoni umpu we-electron?
Umpu we-electron sisixhobo esisetyenziselwa ukuvelisa nokulawula umqadi ogxilileyo wee-electron. Ngokuqhelekileyo iqulethe i-cathode, i-anode, kunye nento egxininisekile evalelwe kwigumbi lokucoca. Umpu we-electron usebenzisa intsimi yombane ukukhawulezisa ii-electron ezikhutshwe kwi-cathode ukuya kwi-anode, ukudala ukuhamba okugxininisiweyo kwee-electron.
Imipu ye-electron isetyenziswa kwiintlobo ngeentlobo zezicelo kwisayensi, kwishishini, nakwiyeza. Usetyenziso oluqhelekileyo lubandakanya i-electron microscopy, i-electron beam lithography, uhlalutyo lomphezulu, ukulinganiswa kwemathiriyeli, ukuwelda komqadi we-electron, kunye nokunyuka komqadi we-electron kukubekwa kwefilim ebhityileyo.
Intlawulo kunye nokuThunyelwa
Inkxaso T / T, PayPal, Alipay, WeChat Pay, njl Nceda uxoxisane nathi ngezinye iindlela zokuhlawula.
→Ukuthumela ngenqanawaInkxaso ye-FedEx, i-DHL, i-UPS, imithwalo yolwandle, kunye nokuthuthwa ngomoya, unokwenza isicwangciso sakho sothutho ngokwezifiso, kwaye siya kubonelela ngeendlela zothutho eziphantsi kwireferensi yakho.
