Xidho caabbinta tuubooyinka dhoobada leeyihiin sifooyinka soo socda marka la barbar dhigo Tuubooyinka kabka-dhagaxa ee hore ee la qaatay, tuubooyinka birta kabka ah ee aan xidhnayn iyo tuubooyinka isku-dhafka dhoobada ah.
Reaction bonded silicon carbide (RBSC) waxay leedahay qaab-dhismeed heersare ah oo u adkaysta, siyaalo wanaagsan oo heerkul sare leh, nabaad guur wanaagsan iyo caabbinta abrasive, guryahan waxaa looga faa'iidaysan karaa codsiyo kala duwan sida xadhkaha tuubooyinka, xusulka dhoobada, buufinta buufinta, tuubooyinka qarxinta iyo qaybaha hydrocyclone.
Dahaaradaha ZPC oo aad uga fog tiilay iyo dahaarka macdan. ZPC silicon carbide ceramics waa iska caabin shoog kulaylka ah iyo adkeysi u adkaysta taas oo keenta waqtiyo orod dheer iyo hoos u dhac.
Dareen-celinta silicion carbide ceramic (RBSIC) waa maaddada xirashada u adkeysiga ku habboon, taas oo si gaar ah ugu habboon xoqidda xoogga leh, walxaha qallafsan, kala-soocidda, xoogga saarista, fuuqbaxa iyo hawlgallada kale. Sababo la xiriira guryaha kor ku xusan, theRBSiC/SiSiC silicon carbide liner suxulka / tuubada xadhkahawaxay si wax ku ool ah uga ilaalin kartaa qaybta xirashada sare iyo heerkulka si loo kordhiyo nolosha adeegga qalabka.

Xaaladda shaqada ee tuubada silikoon carbide dhoobada adkaysiga u leh
Tilmaamaha carbide silicon ee caadiga ah waxaa ka mid ah:
- Cufnaanta hoose
- Xoog sare
- Heerkul sare oo wanaagsan (Reaction bonded)
- Iska caabin oksidation (Reaction bonded)
- Iska caabin naxdin leh kulaylka heer sare ah
- Adayg sare iyo iska caabin xidhid
- Iska caabin kiimiko heer sare ah
- Balaadhinta kulaylka hooseeya iyo dhaqdhaqaaqa kulaylka sare
Codsiyada carbide silicon ee caadiga ah waxaa ka mid ah:
Waxaa loo isticmaalaa wax badan oo loogu talagalay qalitaanka xirashada heerkulka hooseeya marka loo eego dabeecadda heerkulka sare. Codsiyada SiC waa sida cirbadaha ciidda qarxinta, xirmooyinka bamka biyaha baabuurta, xirmooyinka, qaybaha bamka, iyo bakhtiinta bakhtiya kuwaas oo adeegsada qallafsanaanta sare, caabbinta nabarka, iyo iska caabinta daxalka ee carbide of silicon.
- Qaybaha marawaxadaha ee go'an oo dhaqaaqa
- Shaabadadaha, biraha, bambooyinka
- Qaybaha waalka kubbadda
- Xidho taarikada
- Alaabta guriga
- Heerarka kulaylka
- Qalabka wax lagu farsameeyo ee wafer-ka ee Semiconductor
Metallurgy iyo warshadaha korontada: Sababta labadan warshadood la isugu geeyey waa sababta oo ah labada warshadood waxay leeyihiin
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 aad u fiican - iska caabbinta 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.
