Xargaha dhoobada ee Silicon carbide
Dahaarka u adkaysta ee Silicon carbide
Astaamaha Nakhshad ee Silicon Carbide (SiC) Xabahayayaasha u adkaysta Xiro:
(1) Naqshad Jidka Socodka Toosan
Jidh siman oo toosan oo ka soo gelaya ilaa meesha laga baxo ayaa yaraynaysa iska caabinta socodka, taasoo ka dhigaysa xadhkaha SiC mid la qabsan kara codsiyada warshadaha kala duwan.
(2) Atomization horumarsan
Farsamooyinka Dareerayaasha waxaa loo kala qaybiyaa dhibco yaryar iyada oo loo marayo isku dhacyo tangential ah oo si tartiib tartiib ah u soo cidhiidhaya sagxadaha helical ee SiC liner, hubinta qaybinta buufinta lebbiska ah.
(3) Qaab-dhismeed is haysta, oo aan xidhnayn
Kanaalka qulqulka tooska ah ee aan xudunta lahayn ayaa baabi'iya xannibaadaha gudaha, kordhinta dheecaanka dareeraha gudaha cabbirada dhuumaha xaddidan iyadoo laga hortagayo xannibaadaha.
(4) Qaababka buufiska ee laba-geesoodka ah ee hufnaanta la wanaajiyey
Waxay taageertaa qaababka buufinta koofiyadda adag iyo kootada godan, iyada oo bixisa xaglo dabool oo ballaadhan iyo waxqabadka ka-hortagga xidhitaanka ee hawlgallada waxtarka sare leh.
Faa'iidooyinka asaasiga ah marka loo eego agabyada kale:
(1) Iska caabbinta xidhashada oo aan isbarbar dhigin
Adag: Xadhkaha SiC waxay gaadhaan adkaanta Mohs ee 9.5 (vs. 8.0 ee ceramics alumina, 6.0 ee birta-chromium-sare), taas oo awood u siinaysa inay u adkaystaan xidhashada xad dhaafka ah ee qashinka macdanta, dambaska dhuxusha, iyo budada birta ah.
Cimri dheer: Nolosha adeeggu waxay ka badan tahay 5-10x alaab dhaqameed (tusaale caag ama poliurethane liners) ee codsiyada saamaynta sare leh sida miraha kubbadda ama bambooyinka dareeraha ah.
(2) Daxalka iyo Kiimikada aan firfircoonayn
Iska caabinta Asiidhka/Alkali: Waxay u adkaysataa sulfuric acid (98%), sodium hydroxide (50%), iyo cusbada dhalaalay (tusaale NaCl-KCl at 800°C), halka biraha si degdeg ah u daxalaystaan oo polymers-ku hoos u dhaco.
Wasakhda Eber: Dusha aan falcelin lahayn waxay hubisaa nadiifnimada semiconductor ama soosaarka baytariga lithium, si ka duwan xadhkaha birta ee u nugul dheecaanka ion.
(3) Xasilooni heer kul oo aad u daran
U adkaysiga kulaylka: Wuxuu si joogto ah ugu shaqeeyaa 1,600°C (vs. alumina's 1,200°C xadka) oo leh balaarin kulaylka ugu yar (CTE: 4.0×10⁻⁶/℃), ka hortagga dildilaaca kilns ama foornooyinka dhalaalinta.
Iska caabinta shoogga kulaylka: Waxay ilaalisaa sharafta qaabdhismeedka hoos yimaada heerkulka degdega ah (tusaale deminta 1,000C ilaa heerkulka qolka), si ka duwan ceramics-ka jajaban.
(4) Waxtarka Tamarta iyo Nakhshad Fudud
Jajabka Hoose: Dusha SiC ee la iftiimiyay (Ra <0.1 μm) waxay yaraynaysaa iska caabbinta dareeraha 30-50% oo ka soo horjeeda xadhkaha birta adag, gooynta kharashka tamarta
Kaydinta Miisaanka: Cufnaanta 3.1 g/cm³ (marka la barbar dhigo birta 7.8 g/cm³) waxay fududaynaysaa rakibaadda waxayna taageertaa qalabka fudud ee hawada hawada ama qaybaha farsamaynta mobilada.
Shandong Zhongpeng Ceramics Co., Ltd waa mid ka mid ah xalalka alaabta cusub ee silikoon carbide ugu weyn ee Shiinaha. dhoobada farsamada ee SiC: Adkeeyga Moh waa 9 (Adayga cusub ee Moh waa 13), oo leh iska caabin aad u wanaagsan oo nabaadguurka iyo daxalka, nabaad-guurka heersare ah - iska caabin iyo anti-oxidation. Nolosha adeegga sheyga SiC waa 4 ilaa 5 jeer in ka badan 92% walxo aluminium ah. MOR ee RBSiC waa 5 ilaa 7 jeer ka SNBSC, waxa loo isticmaali karaa qaabab aad u adag. Habka xigashada waa mid degdeg ah, gaarsiinta waa sidii balanta ahayd, tayaduna waa labaad ee midna. Had iyo jeer waxaan ku adkaysannaa inaan ka hortagno yoolalkayaga oo aan dib u soo celinno quluubtayada bulshada.
