Cov phiaj xwm no suav nrog kev muaj cov qauv tsim kho nrog ceev thiab xa mus rauTuam Tshoj Mechanical Foob, Silicon Carbide, Dhau li ntawm tseem muaj kev tsim khoom thiab kev tswj hwm, cov cuab yeej tsim khoom siab heev kom paub tseeb tias peb lub sijhawm zoo thiab kev xa khoom, peb lub tuam txhab ua raws li txoj cai ntawm kev ntseeg zoo, ua haujlwm zoo thiab ua haujlwm zoo. Peb lav tias peb lub tuam txhab yuav sim peb qhov zoo tshaj plaws los txo cov neeg siv khoom tus nqi, txo lub sijhawm ntawm kev yuav khoom, cov khoom ruaj khov zoo, ua kom cov neeg siv khoom txaus siab thiab ua tiav qhov teeb meem yeej-yeej.
Nqe lus piav qhia:
Silicon Carbidemuaj cov cuab yeej zoo heev resistant-corrosion, siab mechanical zog, siab thermal conductivity, zoo self-lubrication siv raws li lub ntsej muag foob, bearings thiab hlab nyob rau hauv spacecraft, machinery, metallurgy, luam ntawv thiab dyeing, khoom noj khoom haus, tshuaj, pib kev lag luam thiab hais txog. Thaum lub ntsej muag sic ua ke nrog graphite lub ntsej muag qhov kev sib txhuam yog qhov tsawg tshaj plaws thiab lawv tuaj yeem ua rau cov khoom siv sib khi uas muaj peev xwm ua haujlwm hauv kev ua haujlwm siab tshaj plaws.
Silicon Carbide Basic Properties:
- Tsawg ceev
-High thermal conductivity (ze rau aluminium)
-Qhov zoo thermal shock kuj
- Ua kua thiab roj pov thawj
-High refractoriness (tuaj yeem siv ntawm 1450 ℃ hauv huab cua thiab 1800 ℃ hauv nruab nrab cua)
-Nws tsis cuam tshuam los ntawm corrosion thiab tsis ntub nrog melted aluminium los yog melted zinc
-High hardness
- Tsawg kev sib txhuam coefficient
-Abrasion tsis kam
-Resistant rau cov yooj yim thiab muaj zog acids
-Posheable
-High mechanical zog
Daim ntawv thov Silicon Carbide:
-Mechanical seals, bearings, thrust bearings, thiab lwm yam
- Rotating pob qij txha
- Semiconductor thiab txheej
-Pads Pump Cheebtsam

Feature
Silicon carbide yog tsim nyob rau hauv ob txoj kev:
1) Tsis muaj zog sintered silicon carbide
Tom qab cov khoom siv tsis muaj zog sintered silicon carbide yog etched, cov qauv siv lead ua theem nyob rau hauv 200X optical microscope qhia tau hais tias qhov kev faib tawm thiab qhov loj ntawm cov muaju yog sib xws, thiab cov siv lead ua loj tshaj plaws tsis tshaj 10μm.
2) Cov tshuaj tiv thaiv sintered silicon carbide
Tom qab cov tshuaj tiv thaiv sintered silicon carbide tshuaj kho lub tiaj thiab du seem ntawm cov khoom, cov siv lead ua
Kev faib tawm thiab qhov loj me hauv qab 200X optical microscope yog ib yam, thiab cov ntsiab lus ntawm silicon dawb tsis pub tshaj 12%.
