Graphite ndi allotrope of carbon, a transitional crystal between atomic crystals, metal crystals and molecular crystals.Nthawi zambiri imvi yakuda, yofewa, greasy feeling.Kutentha kwa mpweya kapena okosijeni komwe kumayaka ndi kutulutsa mpweya woipa. organic acids.Kugwiritsidwa ntchito ngati antiwear wothandizila ndi lubricating zinthu, kupanga crucible, elekitirodi, youma batire, pensulo lead.The kukula kwa graphite kuzindikira: zachilengedwe graphite, wandiweyani crystalline graphite, flake graphite, cryptocrystalline graphite, graphite ufa, graphite pepala, kukodzedwa graphite, graphite emulsion, kukod graphite, dongo graphite ndi conductive graphite ufa, etc.
1. kutentha kwambiri kukana: malo osungunuka a graphite ndi 3850 ± 50 ℃, ngakhale pambuyo pa kutentha kwakukulu kwa kutentha kwa arc, kutaya thupi kumakhala kochepa kwambiri, kuwonjezereka kwa kutentha kumakhala kochepa kwambiri. Mphamvu ya graphite imawonjezeka ndi kuwonjezeka kwa kutentha . Pa 2000 ℃, mphamvu ya graphite imawirikiza kawiri.
2. conductive, matenthedwe matenthedwe: madutsidwe a graphite ndi nthawi zana kuposa ore sanali zitsulo. The matenthedwe madutsidwe zitsulo, chitsulo, kutsogolera ndi zitsulo materials.Thermal conductivity amachepetsa ndi kuwonjezeka kutentha, ngakhale pa kwambiri. kutentha kwambiri, graphite mu kutchinjiriza;
3. lubricity: kondomu ntchito graphite zimadalira kukula kwa graphite flake, flake, mikangano coefficient ndi ang'onoang'ono, kondomu ntchito bwino;
4. Kukhazikika kwamankhwala: graphite pa kutentha kwa chipinda ali ndi kukhazikika kwa mankhwala, kukana kwa asidi, kukana kwa alkali ndi kukana kwa organic zosungunulira;
5. pulasitiki: kulimba kwa graphite ndikwabwino, kumatha kuphwanyidwa kukhala pepala lochepa kwambiri;
6. matenthedwe mantha kukana: graphite pa firiji kutentha pamene ntchito akhoza kupirira kusintha kwambiri kutentha popanda kuwonongeka, kusintha kutentha, voliyumu wa graphite kusintha pang'ono, si kusweka.
1. kusanthula kamangidwe: mpweya wokhazikika, chinyezi, zonyansa, etc.;
2. Kuyesa kwa thupi: kuuma, phulusa, kukhuthala, kukongola, kukula kwa tinthu, kusinthasintha, mphamvu yokoka yeniyeni, malo enieni, malo osungunuka, ndi zina zotero.
3. Kuyesa kwazinthu zamakina: kulimba kwamphamvu, brittleness, kuyesa kupindika, kuyesa kwamphamvu;
4. kuyezetsa ntchito kwamankhwala: kukana madzi, kukhazikika, kukana kwa asidi ndi alkali, kukana kwa dzimbiri, kukana nyengo, kukana kutentha, etc.
5. Zinthu zina zoyeserera: madutsidwe amagetsi, matenthedwe matenthedwe, mafuta, kukhazikika kwamankhwala, kukana kugwedezeka kwamafuta
