Qaabka Gaarka ah ee Silicon Carbide dhoobada Walaxda Cusub

Silikoon carbide (si-sic) sic dhoobada falcelinta-ku-xidhan, oo laga sameeyay porosity eber iyadoo lagu buuxinayo porosity furan bir silikoon (si). Sababtoo ah sifada porosity eber waa eber, kulaylka kuleylku waa in ka badan laba jeer ee oxide bonded sic's, xoog laabashada ayaa ka badan 5 jeer marka la barbar dhigo oksaydh bonded sic.
Sifada gaarka ah ee Sic waa awooda ay ku ilaalinayso awooda sare heerkulka qolka ilaa 1,380°c. Sidoo kale waxay leedahay iska caabin oksaydhismeed oo aad u sarreeya, caabbinta kiimikaad iyo caabbinta xidhashada. Loo isticmaalo sida alwaax, rullaluistu, tuubada shucaaca iyo biiyaha gubi iwm.
Reaction Bonded Silicon Carbide waxay u dulqaadataa asiidhyo iyo alkalis balaadhan oo kala duwan. Iyo wax qabad heer sare ah oo xoog sare leh, qallafsanaan sare, caabbinta xidhashada sare, iska caabinta heerkulka sare, iska caabinta daxalka. Noocyada kala duwan ee qaababka qaybaha gaarka ah waxay ku habboon yihiin macdanta, petrochemical, wax soo saarka birta, hawada hawada iyo warshadaha nukliyeerka, sida deegaan gaar ah. Waxaan samayn karnaa cabbir kasta oo lagu bixiyo si waafaqsan codsiga macaamiisha.

Xiro caabbinta, xoogga heerkulka sare iyo iska caabinta daxalka ayaa ka dhigaya Reaction Bonded SiC wax ku habboon xirashada qaybaha, sida boolal, taargooyin iyo mashiinnada. Waxa kale oo loo istcimaali karaa xadhkaha riixa ee qaadi kara culaysyo aad u sarreeya oo dareere wasakhaysan.

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. Waxaan had iyo jeer ku adkeysaneynaa inaan ka hortagno yoolalkayaga oo aan dib u soo celinno quluubtayada bulshada.
