Tuubooyinka shucaaca ee Silicon carbide

Tuubooyinka shucaaca ee Silicon carbidewaa qaybo dhoobada horumarsan oo si weyn loogu aqoonsaday waxqabadkooda gaarka ah ee heerkulka sare iyo codsiyada warshadaha wasakhaysan. Sifooyinkooda gaarka ah iyo la qabsiga qaabdhismeedku waxay ka dhigayaan lama huraan marka loo baahdo jawiga hawlgalka. Hoos waxaa ku yaal dulmar ku saabsan faa'iidooyinkooda iyo codsiyadooda muhiimka ah.

1. Guryaha Agabka Sare

SiC waa walxo dhoobo ah oo wax qabad sare leh oo leh astaamo aad u wanaagsan:

(1) Iska caabin heerkul aad u daran: Awood u leh hawlgal joogto ah oo heerkul ah ilaa 1600 ° C iyo soo-gaadhista muddada-gaaban ee ka sarreysa 1800 ° C, oo aad uga sarreeya xalalka birta ku salaysan ee dhaqameed.

(2) Dhaqdhaqaaqa Kulaylka Sare: Iyada oo kuleyliyaha kuleylka 2-3 jeer ka sarreeya biraha, tuubooyinka iftiinka ee Silicon carbide waxay awood u siinayaan kuleyl degdeg ah iyo qaybinta heerkulka isku midka ah.

(3) Balaadhinta kulaylka hooseeya: Balaadhintooda kulaylka ugu yar waxay yaraynaysaa diiqada inta lagu jiro isbedbeddelka heerkulka, hubinta xasilloonida qaabdhismeedka.

(4) Daxalka iyo Iska caabinta Oxidation: U adkaysta asiidhka, alkalis, biraha dhalaalay, iyo gaaska gardarada leh, xataa haddii ay ku jiraan xaalado heerkul sare oo daba dheeraaday.

2.Dhaqanka qaabdhismeedka

Tuubooyinka shucaaca ee Silicon carbide waxa lagu habayn karaa baahiyaha warshadeed ee kala duwan:

(1) Naqshado La Habayn Karo: Lagu heli karo qaabayn toosan, U-qaabeeya, ama qaab W-qaabeeya si loo wanaajiyo qaybinta kulaylka iyo ka faa'iidaysiga booska.

(2) Is-dhexgalka Adag: La jaanqaadi kara flanges birta ama nidaamyada xidhidhiyaha dhoobada ee isku xirka-cadayga ee xirmooyinka adag.

1. Faa'iidooyinka hawlgalka

(1) Waxtarka Tamarta: Heerarka kulaylka sare wuxuu yareeyaa isticmaalka tamarta isagoo awood u siinaya wareejinta kulaylka degdega ah.

(2) Nolosha Adeegga Dheer: Tuubbooyinka shucaaca ee Silicon carbide waxay caadi ahaan socdaan 3-5 jeer in ka badan beddelka birta ee bey'ada adag, yaraynta wakhtiga dhimista iyo kharashka beddelka.

(3) Iska caabinta shoogga kulaylka: Waxay u adkaysataa wareegyada kuleylka iyo qaboojinta degdega ah iyada oo aan dillaacin, ku habboon hababka u baahan isbeddelka heerkulka joogtada ah.

4. Codsiyada Warshadaha Muhiimka ah

Tuubooyinka shucaaca ee Silicon carbide waxay aad ugu fiican yihiin qaybaha muhiimka ah:

(1) Metallurgy: Waxaa loo isticmaalaa foornooyinka baabi'inta, foornooyinka karbuunta, iyo nidaamyada birta ee daaweynta kulaylka isku midka ah.

(2) Habaynta Kiimikada: U adeega sida tuubooyinka falcelinta ama taageereyaasha kicinta ee reactors heerkulka sare iyo foornooyinka pyrolysis.

(3) Waxsoosaarka dhoobada/Muraayadaha: Hubi in si sax ah loo koontaroolo heerkulka foornada weelka lagu shido iyo foornada dhalaalaysa.

(4) Nidaamyada Deegaanka: Waxaa la geeyaa meelaha lagu gubi qashinka iyo waaxaha daawaynta qiiqa si ay u xakameeyaan gaaska daxalka leh ee heerkul sarreeya.

5. Faa'iidooyinka Isbarbardhigga ah ee ka badan beddelka:

6. Maxaad u doorataa tuubooyinka shucaaca ee Silicon carbide?

Tubooyinka shucaaca ee Silicon carbide ayaa ah doorashada ugu fiican ee warshadaha mudnaanta siinaya:

(1) Degenaansho heerkul aad u daran iyada oo aan hoos loo dhigin waxqabadka.

(2) Isku hallaynta muddada-dheer ee jawiga daxalka ama oksaydhka.

(3) Tamar-ku-ool iyo kuleyl isku mid ah oo loogu talagalay hababka saxda ah ee loo wado.

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.
