- COV ZOO NTAWM COV REACTION BONDED SILICON CARBIDE
Cov khoom Reaction Bonded Silicon Carbide (RBSC, lossis SiSiC) muaj kev tawv heev / kev tiv taus kev sib txhuam thiab kev ruaj khov tshuaj lom neeg zoo heev hauv cov chaw ua haujlwm hnyav. Silicon Carbide yog cov khoom siv hluavtaws uas ua rau pom cov yam ntxwv ua tau zoo xws li:
lKev tiv thaiv tshuaj lom neeg zoo heev.
Lub zog ntawm RBSC yog yuav luag 50% ntau dua li ntawm feem ntau nitride bonded silicon carbides. RBSC yog qhov zoo heev corrosion tsis kam thiab antioxidation ceramic .. Nws tuaj yeem tsim rau hauv ntau yam desulpurization nozzle (FGD).
lKev hnav zoo heev thiab kev cuam tshuam tsis kam.
Nws yog qhov zoo tshaj plaws ntawm cov thev naus laus zis ceramic loj uas tiv taus kev txhuam. RBSiC muaj qhov nyuaj siab ze li ntawm pob zeb diamond. Tsim los siv rau hauv cov ntawv thov rau cov duab loj uas cov qib refractory ntawm silicon carbide ua rau pom kev hnav lossis puas tsuaj los ntawm kev cuam tshuam ntawm cov khoom loj. Tiv taus kev cuam tshuam ncaj qha ntawm cov khoom me me nrog rau kev cuam tshuam thiab kev txhuam ntawm cov khoom hnyav uas muaj slurries. Nws tuaj yeem tsim rau hauv ntau yam duab, suav nrog cov duab cone thiab tes tsho, nrog rau cov khoom tsim ua ntau dua uas tsim rau cov khoom siv koom nrog hauv kev ua cov khoom siv raw.
lKev tiv thaiv thermal zoo heev.
Cov khoom sib txuas ua ke silicon carbide muab kev tiv thaiv thermal zoo heev tab sis tsis zoo li cov khoom siv ceramics ib txwm muaj, lawv kuj ua ke qhov ceev qis nrog lub zog siab.
lLub zog siab (nce lub zog ntawm qhov kub thiab txias).
Cov tshuaj tiv thaiv bonded Silicon carbide khaws cia feem ntau ntawm nws lub zog kho tshuab ntawm qhov kub siab thiab qhia txog qib qis heev ntawm kev nkag, ua rau nws yog thawj qhov kev xaiv rau cov ntawv thov load-bearing hauv qhov ntau ntawm 1300ºC txog 1650ºC (2400ºC txog 3000ºF).
