Kev piav qhia:
Silicon Carbide muaj cov khoom zoo ntawm kev tiv taus corrosion zoo heev, lub zog siab, kev ua haujlwm thermal siab, kev siv lubrication zoo siv ua lub ntsej muag foob, bearings thiab raj hauv spacecraft, machinery, metallurgy, luam ntawv thiab dyeing, khoom noj khoom haus, tshuaj, kev lag luam tsheb thiab lwm yam. Thaum cov ntsej muag sic sib xyaw nrog graphite ntsej muag qhov kev sib txhuam yog qhov me tshaj plaws thiab lawv tuaj yeem ua rau cov foob pob hluav taws xob uas muaj peev xwm ua haujlwm hauv qhov xav tau ua haujlwm siab tshaj plaws.
Silicon Carbide Cov Khoom Siv Tseem Ceeb:
-Qhov ceev tsawg
-Kev ua kom muaj cua sov siab (ze li txhuas)
-Kev ua haujlwm thermal shock zoo
-Cov pov thawj ua kua thiab roj
-High refractoriness (tuaj yeem siv tau ntawm 1450 ℃ hauv huab cua thiab 1800 ℃ hauv huab cua nruab nrab)
-Nws tsis raug cuam tshuam los ntawm corrosion thiab tsis ntub nrog melted txhuas los yog melted zinc
-Kev nyuaj siab
-Kev sib txhuam coefficient tsawg
-Kev tiv thaiv kev puas tsuaj
-Tiv taus cov kua qaub yooj yim thiab cov kua qaub muaj zog
-Polishable
-Lub zog kho tshuab siab
Daim Ntawv Thov Silicon Carbide:
- Cov ntsaws ruaj ruaj, cov bearings, cov bearings thrust, thiab lwm yam
-Cov pob qij txha tig
-Semiconductor thiab txheej
-Pads Twj Tso Kua Mis Cheebtsam
-Cov khoom siv tshuaj lom neeg
-Cov iav rau cov tshuab laser industrial.
- Cov reactors uas ntws tas mus li, cov khoom hloov pauv cua sov, thiab lwm yam.
Feature
Silicon carbide yog tsim los ntawm ob txoj kev:
1) Cov roj silicon sintered uas tsis muaj zog
Tom qab cov khoom siv silicon carbide sintered tsis muaj siab raug etched, daim duab qhia txog theem siv lead ua nyob rau hauv 200X lub tshuab tsom iav pom kev qhia tias qhov kev faib tawm thiab qhov loj ntawm cov siv lead ua yog sib xws, thiab cov siv lead ua loj tshaj plaws tsis pub tshaj 10μm.
2) Cov tshuaj tiv thaiv sintered silicon carbide
Tom qab cov tshuaj tiv thaiv sintered silicon carbide chemically kho cov seem tiaj tus thiab du ntawm cov khoom siv, cov siv lead ua
Kev faib tawm thiab qhov loj me nyob rau hauv 200X lub tshuab tsom iav yog sib xws, thiab cov ntsiab lus silicon dawb tsis pub tshaj 12%.
