Xidho tuubbooyinka dhoobada ee Silicon carbide Resistant
Silicon carbide ceramic: adkaanta Moh waa 9.0 ~ 9.2, oo leh iska caabin aad u wanaagsan oo nabaadguurka iyo daxalka, caabbinta-iska-caabbinta iyo anti-oxidation. Waxay 4 ilaa 5 jeer ka xoog badan tahay nitride ku xidhan silikon carbide. Nolosha adeeggu waxay 7 ilaa 10 jeer ka dheer tahay alaabta aluminiumka ah. MOR ee RBSiC waa 5 ilaa 7 jeer ka SNBSC, waxa loo isticmaali karaa qaabab aad u adag.
Silicon carbide xidho iska caabin ah, waxa lagu farsameeyey ka silikon carbide iyo carbon heerkulka sare leh, iska leh nooc ka mid ah silikon carbide Product.The silicon carbide xirtaan iska caabin qaybaha si weyn loo isticmaalo in macdanta, ore burburin, baadhista iyo gaadiidka ee xidho sare, dareere daxalka sare, sidoo kale aad ugu habboon alaabta farsamada leh sax sare iyo shuruudaha shaabadeynta, sida bamka cadaadiska sare, bamka magnetka cusub ee wax iska caabin ah silikoon xidho. bushing waxa uu leeyahay sifooyinka of engegnaantooda sare, caabbinta xirashada sare, iska caabin saamaynta, caabbinta heerkulka sare, acid iyo alkali iska caabin daxalka iyo wixii la mid ah, iyo nolosha adeegga dhabta ah waa in ka badan 6 jeer in of polyurethane.It waa gaar ahaan ku haboon hawlgalka ee kala-soocidda, fiirsashada iyo fuuqbaxa abrasive iyo qallafsanaan-hadhuudh qalab, ayaa si guul leh codsatay in alaabooyin badan oo silikoon carbide xidho waa mines carbide. alaab-qeybiye, qallafsanaan labaad oo kaliya in diamond, oo leh caabbinta xirashada sare, sifooyinka nolosha dheer ee adeeg. The xidho caabbinta biibiile iyo xusul in soo saaray la silicon carbide xidho dahaarka iska caabin ah, ay dhumucdiisuna waxay dahaarka dhoobada waa 6-35mm, qaab-dhismeedka waa in la rakibo tube dhoobada hore sintered galay tube bir u dhiganta, iyadoo xabagta in middle.Wear caabbinta caabbinta hore ee tuubooyinka dhoobada - dhagaxyo iska caabin ah ee soo socda ayaa la barbar dhigay guryaha birta ah. tuubooyinka iyo tuubooyinka isku dhafan dhoobada.
Reaction bonded silicon carbide (RBSC) waxay leedahay qaab-dhismeed adkeysi heer sare ah, sifooyin wanaagsan oo heerkul sare leh, nabaad guur wanaagsan iyo caabbinta abrasive, guryahan waxaa loo isticmaali karaa noocyo kala duwan oo codsiyo ah sida xargaha tuubada, xusulka dhoobada, buufinta buufinta, tuubooyinka qarxinta iyo qaybaha hydrocyclone.
Dahaarka ZPC-da oo aad uga fog tiilay iyo biraha. ZPC silikoon 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 shoog kulayl 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
- Kuleylleyda
- 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 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.
