Silicon carbide Mitanda ndi odzigudubuza
ZPC-RBSiC (SiSiC) mtanda matabwa ali ndi mphamvu apamwamba ndipo palibe zopindika ngakhale kutentha kwambiri. Komanso matabwa amasonyeza moyo wautali wa ntchito. Miyendo ndi mipando yoyenera kwambiri yamoto yopangira zovala zaukhondo komanso ntchito zamagetsi zadothi. Shang mei RBSiC (SiSiC) ili ndi matenthedwe abwino kwambiri, choncho imapezeka kuti ipulumutse mphamvu ndi kulemera kochepa kwa galimoto yamoto.
Miyendo ya silicon carbide ndi zodzigudubuza zimagwiritsidwa ntchito ngati mafelemu onyamula mu ng'anjo zopangira zadothi, zomwe zimatha kulowa m'malo mwa mbale ya silicon yokhala ndi oxide ndi mullite positi chifukwa ali ndi zabwino monga kusunga malo, mafuta, mphamvu komanso kufupikitsa nthawi yowombera, komanso nthawi yamoyo. wa zipangizo zimenezi kangapo ena ndi abwino kwambiri uvuni mipando. Silicon carbide beam imagwiritsidwa ntchito makamaka ngati katundu wonyamula mamembala ang'onoang'ono, uvuni wa shuttle ndi ng'anjo iwiri. Itha kugwiritsidwanso ntchito ngati mipando yakuwotchera m'makampani a ceramic ndi refractory.
Miyendo yokhala ndi mphamvu yayikulu, yogwiritsira ntchito nthawi yayitali popanda kupindika, makamaka yoyenera kung'anima ngalande, uvuni wamoto, pawiri - wosanjikiza ng'anjo yodzigudubuza ndi ng'anjo ina yamafakitale - yokhala ndi chimango. Makalabu amagwira ntchito tsiku ndi tsiku - zoumba zadothi zogwiritsidwa ntchito, zadothi zaukhondo, Ceramic Yomanga, Magnetic material ndi malo otenthetsera otenthetsera amoto wodzigudubuza.

Makhalidwe:
*Kukana kwambiri abrasion
*Kugwiritsa ntchito mphamvu zambiri
*Palibe deformation pansi pa kutentha kwakukulu
* Kulekerera kwakukulu kwa kutentha kwa 1380-1650 digiri Celsius
*Kukana dzimbiri
* Mphamvu yopindika yayikulu pansi pa digiri ya 1100: 100-120MPA
Shandong Zhongpeng Special Ceramics Co., Ltd ndi imodzi mwamayankho akulu kwambiri a silicon carbide ceramic ku China. SiC ukadaulo wa ceramic: Kulimba kwa Moh ndi 9 (Kulimba kwa Moh Chatsopano ndi 13), kukana kwambiri kukokoloka ndi dzimbiri, abrasion yabwino - kukana ndi anti-oxidation. Moyo wautumiki wa SiC ndi 4 mpaka 5 nthawi yayitali kuposa 92% alumina. MOR ya RBSiC ndi 5 mpaka 7 nthawi ya SNBSC, itha kugwiritsidwa ntchito pazinthu zovuta kwambiri. Ndondomeko yobwereketsa ndi yofulumira, yobweretsera ndi monga momwe inalonjezedwa ndipo khalidweli ndi lachiwiri kwa wina aliyense. Nthawi zonse timalimbikira kutsutsa zolinga zathu ndikubwezeranso mitima yathu kwa anthu.
