Chiyambi cha graphite flexible feel

Kutentha kwakukulu kwa graphite kumamveka kumakhala ndi kulemera kopepuka, kusokonezeka kwabwino, kuchuluka kwa kaboni,kukana kutentha kwakukulu, palibe volatilization pa kutentha kwakukulu,kukana dzimbiri, chaching'onomatenthedwe madutsidwendi kusunga mawonekedwe apamwamba.

The mankhwala ali ubwino zotsatirazi: pambuyo 1800 ~ 2500 ℃ mkulu kutentha mankhwala, kusiyana kutentha pakati pa mfundo ziwiri za anamva si oposa 50 ℃, kotero ntchito mankhwala ndi khola. Chifukwa ndikupanga kosalekeza, kumatha kutsimikizira kufanana kwa zinthu zomwe zimamveka m'lifupi ndi kutalika kulikonse.

Poyerekeza ndimpweya wa carbonankachitira pa kutentha otsika (m'munsimu 900 ℃), graphite ankaona kuchitiridwa pa kutentha (pamwamba 2200 ℃) ali ubwino zotsatirazi:

(1) The adsorption wa madzi nthunzi ndi mipweya ina pa graphite anamva ndi 2 maginitude magnitude kuposa pa carbon ankamva kuchitiridwa pa kutentha otsika. Kwa zida zambiri zotsekedwa zazombo zomwe zimafunikira kutsukidwa, chiyero chamlengalenga ndichofunikira kwambiri. Komabe, chifukwa cha kuchuluka kwa kutentha kwa mpweya wotentha, kumakhala kovuta kuti vacuumize chombo.

(2) Ma graphite amamva kuti ali ndi kukana kwamphamvu kwa matenthedwe a okosijeni. Kapangidwe ka kaboni kopanda graphitization ndi mtundu wosanjikiza wosanjikiza. Kukhalapo kwa zolakwika zosiyanasiyana zamapangidwe kumapangitsa kuti kusanja kwake kukhale kokulirapo, ndipo ndikosavuta kugwidwa ndi maatomu okosijeni ndi okosijeni. Latisi yabwino komanso kuyitanitsa makonzedwe amitundu itatu a graphite amamveka pambuyo pa chithandizo cha kutentha kwambiri kumachepetsa kwambiri kusanjikiza kwakutali ndikupangitsa kuti kusakhale kosavuta kugwidwa ndi maatomu okosijeni, motero kumakulitsa kwambiri mphamvu ya antioxidant.

(3) Kuyera kwa graphite kumamveka ndipamwamba, ndipo zomwe zili ndi mpweya ndizoposa 99.5%. Mpweya wa carbon womwe umakhala wochepa kutentha kwa mpweya umamveka nthawi zambiri umakhala wosakwana 93%, zomwe ndizosavuta kuwononga chilengedwe mung'anjo.

Mwachidule, kutentha kwamphamvu kwa graphite kumamveka kumakhala ndi zotsatira zabwino komanso moyo wautali wautumiki kuposa kutentha kwa mpweya wochepa.
