- Qhov zoo ntawm cov kev tawm tsam ua si Silicon Carbide
Cov yeeb yam sib tsoo Silicon carbide (RBSC, lossis chaw soic) kev ua phem rau huab cua phem / puas tsis txaus ntseeg thiab cov tshuaj ruaj khov nyob hauv ib puag ncig. Silicon Carbide yog cov khoom siv hluavtaws uas ua rau pom cov yam ntxwv zoo ua tau suav nrog:
lTshuaj lom neeg zoo heev.
Lub zog ntawm RBSC yog yuav luag 50% ntau dua li ntawm cov nitride feem ntau ua qhev silicon carbides. RBSC yog qhov zoo heev corrosion tsis kam thiab antioxidation ceramic .. Nws tuaj yeem tsim mus rau ntau yam ntawm desulpurizzle (FGD).
lKev hnav zoo nkauj thiab cuam tshuam tsis kam.
Nws yog pinnacle ntawm loj nplai ua kev tiv thaiv kev tiv thaiv ceramic. RBSIC muaj kev nyuaj siab mus txog ntawm pob zeb diamond. Tsim los siv rau hauv cov ntawv thov rau cov tub rog loj uas cov qib carmide yog kev ua kom muaj kev cuam tshuam thiab kev puas tsuaj ntawm cov khoom loj. Tiv thaiv kom ncaj qha rau kev cuam tshuam ntawm lub teeb thiab cuam tshuam thiab swb rau kev sib cais ntawm cov khib nyiab hnyav uas muaj slurries. Nws tuaj yeem tsim ua ntau yam ntawm cov duab, suav nrog cov duab, nrog rau cov duab, nrog rau cov khoom siv ntau dua tsim kev cuam tshuam nrog cov khoom siv raw.
lCov boilal zoo heev tsis kam.
Cov yeeb ncuab sib xyaw ua silicon carbide Cheebtsam muab cov khoom siv hluav taws xob zoo tsis zoo tab sis tsis zoo li niaj hnub sib xyaw ua ke nrog kev siv hluav taws xob qis.
lSiab zog (nce lub zog ntawm qhov kub).
Cov yeeb yam sib tsoo Silicon carbide khaws cov tshuab uas muaj zog kub thiab cov khoom siv thawj zaug rau cov khoom siv thauj khoom hauv thaj tsam 1300ºC (2400ºC mus rau 3000ºF).

- Kev Lag Luam RoojRau cov kev sib tw sib tsoo Silicon carbide:
Lub zog tiam, tsuas tiam, tshuaj lom neeg, petrochemical, kiln, machinery manufacturing kev lag luam, zaub mov & metallurgy thiab meters.
Txawm li cas los xij, tsis zoo li cov hlau thiab lawv cov alloys, tsis muaj kev lag luam kev lag luam qauv kev ua lag luam qauv rau silicon carbide. Nrog ntau cov kev sib xyaw ua ke, cov tswv yim, kev tsim khoom lag luam, cov tuam txhab kev tsim khoom thiab cov khoom siv carbon carbon Koj xaiv cov khoom xa khoom yuav txiav txim siab qib thiab cov khoom uas koj tau txais.
