SiC Chisimbiso Mhete

Tsanangudzo:

Silicon Carbide ine chivakwa cheakanakisa resistant-corrosion, yakakwira mechani simba, yakakwira yekupisa conductivity, yakanaka self-lubrication inoshandiswa sechisimbiso zviso, fani uye machubhu muspacecraft, michina, simbi, kudhinda uye dhayi, chikafu, mishonga, indasitiri yemotokari uye zvakadaro. on. Kana zviso zve sic zvasanganiswa nezviso zve graphite kukwesha ndiko kudiki uye vanogona kugadzirwa kuva mechanical seals izvo zvinokwanisa kushanda mupamusoro pekushanda zvinodiwa.

Silicon Carbide Basic Properties:

-Low density

-High thermal conductivity (pedyo nealuminium)

-Good thermal shock resistance

-Uchapupu hwemvura uye gasi

-High refractoriness (inogona kushandiswa pa1450 ℃ mumhepo uye 1800 ℃ mumhepo isina kwayakarerekera)

-Haina kukanganiswa nekuora uye hainyoro nealuminium yakanyunguduka kana zinc yakanyunguduka.

-High kuoma

-Low friction coefficient

-Abrasion resistance

-Inoramba kune yakakosha uye yakasimba asidhi

-Polisheable

-High mechanical simba

Silicon Carbide Kushandisa:

-Mechanical seals, mabearings, thrust bearings, nezvimwe

-Majoini anotenderera

-Semiconductor uye kupfeka

-Pads Pump zvikamu

-Kemikari zvikamu

-Mirrors yemaindasitiri Laser masisitimu.

- Inoenderera-inoyerera reactor, heat exchangers, nezvimwe.

Feature
Silicon carbide inoumbwa nenzira mbiri:

1)Pressureless sintered silicon carbide

Mushure mekunge iyo isina kudzvanywa sintered silicon carbide zvinhu yakadzikwa, iyo crystal phase diagraph iri pasi pe200X optical microscope inoratidza kuti kugovera uye ukuru hwemakristasi yunifomu, uye kristaro hombe haipfuure 10μm.

2) Reaction sintered silicon carbide

Mushure mekuita sintered silicon carbide inobata kemikari yakatsetseka uye yakatsetseka chikamu chechinhu, iyo crystal
kugovera uye saizi pasi pe200X optical microscope iyunifomu, uye yemahara silicon yemukati haipfuure 12%.
