SiC Sealing nplhaib

Nqe lus piav qhia:

Silicon Carbide muaj cov cuab yeej zoo heev tiv taus corrosion, siab mechanical zog, siab thermal conductivity, zoo self-lubrication siv raws li lub ntsej muag, bearings thiab hlab nyob rau hauv spacecraft, machinery, metallurgy, printing thiab dyeing, khoom noj khoom haus, tshuaj, pib kev lag luam thiab thiaj li nyob. ntawm. 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)

-Zoo thermal shock tsis kam

-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

-Siab hardness

-Tsawg kev sib txhuam coefficient

-Abrasion tsis kam

-Resistant mus rau hauv paus thiab muaj zog acids

-Polisheable

-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

-Chemical Cheebtsam

-Daim iav rau industrial laser tshuab.

- Nruam-flow reactors, kub exchangers, thiab lwm yam.

Feature
Silicon carbide yog tsim nyob rau hauv ob txoj kev:

1) Pressureless 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) Rection 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%.
