Ndezvipi zvakanakisa zvimiro zveakawedzera graphite

1, Mechanical basa:
1.1High compressibility uye kusimba: kune yakawedzera graphite zvigadzirwa, kuchine akawanda akavharwa madiki akavhurika nzvimbo dzinogona kusimbiswa pasi pekuita kwesimba rekunze. Panguva imwecheteyo, vane kusimba nekuda kwekukakavadzana kwemhepo munzvimbo diki dzakavhurika.
1.2Kuchinja-chinja: kuoma kwacho kwakadzikira. Inogona kutemwa nemidziyo yakajairwa, uye inogona kukuvadzwa nekukotamiswa zvisina tsarukano;
2. Mabasa emuviri nemakemikari:
2.1 Kuchena: iyo yakagadziriswa kabhoni yemukati inenge 98%, kana kutopfuura 99%, inokwana kuzadzisa zvinodiwakuchena kwepamusorozvisimbiso mune simba uye mamwe maindasitiri;
2. Density: thebulk densityyeflake graphite ndeye 1.08g/cm3, iyo yakawanda density yeyakawedzerwa graphite ndeye 0.002 ~ 0.005g/cm3, uye density yechigadzirwa i0.8 ~ 1.8g/cm3. Naizvozvo, iyo yakawedzera graphite zvinhu yakareruka uye epurasitiki;
3. Tembiricha kuramba: ne theoretically, iyo yakawedzera graphite inogona kumira - 200 ℃ kusvika 3000 ℃. Sechisimbiso chekurongedza, chinogona kushandiswa zvakachengeteka pa - 200 ℃ ~ 800 ℃. Iyo ine mabasa akanakisa ekushaya embrittlement, hapana kuchembera pakudziya kwakadzika, hapana kupfava, hapana deformation uye hapana kuora pakupisa kwakanyanya;
4. Corrosion resistance: ine husimbe hwemakemikari. Kuwedzera kune dzimwe tembiricha dzakananga dzemaoxidants akasimba akadai seaqua regia, nitric acid, sulfuric acid uye halogen, inogona kushandiswa kune midhiya yakawanda yakadai seasidhi, alkali, munyu, mvura yegungwa, chiutsi uye organic solvent;
5. Excellent thermal conductivityuye diki yekupisa kwekuwedzera coefficient. Iyo paramita yaro iri padyo neiyo yakafanana kurongeka kwehukuru hwehuviri chikamu data cheyakajairwa chisimbiso michina. Inogonawo kuvharwa zvakanaka pasi pemamiriro ekushanda ekushisa kwepamusoro, cryogenic uye kuchinja kwekushisa kwakapinza;
6. Radiation resistance: kuzviisa pasi penyuturoni rays γ Ray α Ray β X-ray irradiation kwenguva yakareba pasina shanduko yakajeka;
7. Impermeability: yakanaka impermeability kune gasi uye mvura. Nekuda kwehukuru hwepamusoro simba rekuwedzera graphite, zviri nyore kuumba yakaonda kwazvo gasi firimu kana yemvura firimu kutadzisa yepakati kupinda;
8. Self lubrication: iyo yakawedzerwa graphite ichiri kuchengetedza iyo hexagonal ndege yakaturikidzana chimiro. Pasi pekuita kwesimba rekunze, zvidimbu zvendege zviri nyore kutsvedza zvishoma uye kuzvizora kwega kunoitika, izvo zvinogona kudzivirira kupfekwa kweshaft kana valve rod.
