Silikoon carbide (SiC) tuubooyinka gubida
Nidaamyada heerkulka sare halkaasoo xakamaynta dareeraha, caabbinta nabaad-guurka, iyo xasiloonida kulaylku ay muhiim yihiin,Silikoon carbide (SiC) ee sanbabadau istaag sida yaab injineernimada. Si ka duwan sida dhoobada caadiga ah ama biraha birta ah, guryaha gaarka ah ee SiC ayaa wax ka qabta caqabadaha gubashada, kicinta, iyo hababka buufinta warshadaha. Maqaalkani waxa uu sahamiyaa sababta ay warshaduhu u sii kordhinayaan qaadashada SiC nozzles si ay wax uga beddelaan waxqabadka codsiyada ugu baahida badan.
1. Waxaa loo farsameeyay deegaanka dareeraha daran
SiC nozzles waxay aad ugu fiican tahay maaraynta xawaaraha sare, dareeraha heerkulka sare leh iyo gaaska:
(1) Iska caabbinta Nabaadguurka: U adkeyso walxaha nabaadguurka ah ee ku jira duritaanka dhuxusha ee dhuxusha, nidaamyada ciid-qarxinta, ama gantaallada iyaga oo aan lahayn qallafsanaan-xirmo.
(2) Badbaadinta shoogga kulaylka: Si degdeg ah u wareeg inta u dhaxaysa heerkulka aadka u daran (tusaale shidaalka lagu duro foornooyinka birta ah) iyada oo aan dillaacin, taas oo ay ugu wacan tahay balaarinta kulaylka hooseeya ee SiC.
(3) Firfircoonida Kiimikada: Iska ilaali daxalka ka imanaya buufinta acidic/alkaline, cusbada dhalaalaysa, ama ololka oksaydhka ah, hubinta joomatari orifice joogto ah.
2. Xakamaynta socodka saxda ah ee geedi socodka halista ah
Codsiyada dalbanaya saxnaanta heerka-yar, SiC nozzles waxay keenaysaa isku hallayn aan la isku halayn karin:
(1) Joometry Orifice Jooga: Ilaali heerka qulqulka saxda ah iyo qaababka buufinta xitaa ka dib soo-gaadhista dheer ee deegaanka 1500°C+, si ka duwan biraha rogma ama ceramics hoos u dhiga.
(2) Xiritaanka oo la dhimay: Dhammaystirka dusha sare ee siman waxa ay yaraynaysaa ururinta walxaha ku jira cirbadaha shidaalka ama hababka buufinta kiimikada.
(3) Dulqaadka Cadaadiska Sare: U adkeyso cadaadiska biyaha ee ka sarreeya 500 MPa, oo ku habboon jarista biyaha jetka ama kicinta hawada sare.
3. Awood-siinta gubashada waxtarka sare leh
SiC nozzles ayaa fure u ah wanaajinta nidaamyada gubashada tamarta xoogga leh:
(1) Xasilloonida Ololka: Naqshad u adkaysata kulaylku waxay hubisaa isku-dhafka shidaalka-hawada ee marawaxadaha gaaska ama gubayaasha warshadaha, yaraynta meelaha kulul iyo qiiqa NOx.
(2) Dabacsanaanta Shidaalka: La jaanqaadi kara hydrogen, shidaalka noolaha, ama saliidaha culus, taageeraya u gudubka ilaha tamarta waara.
(3) Waxtarka kulaylka: Yaree kulaylka luminaya gidaarada sababtoo ah kulaylka sare ee SiC, hagaajinta waxtarka qolka gubashada ilaa 15%.
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.
