Okugqwesileyo kwe-Thermal Conductivity kunye nokuzinza kokutywina
ITheyiphu yeGraphite eyomeleziweyo eyomeleziweyo igcina ukusebenza kakuhle kobushushu begraphite: i-longitudinal thermal conductivity 140-280 W/(m·K), transverse conductivity thermal 45-95 W/(m·K); isakhiwo sethanki siqinisekisa izinga lokunyanzeliswa kwe-18% -45% (ngaphantsi kwe-3 MPa) kunye nereyithi ye-rebound Enkulu kunokuba okanye ilingana ne-82%, enokugcina ngokuzinzileyo ukudibanisa ukutywinwa kunye nokusebenza kakuhle kwe-thermal nangaphantsi kobushushu obutshintshileyo kunye noxinzelelo.
Ukumelana noBuqondo obuBanzi kunye noKuxhathisa ukuMhlwa
Inokusebenza ngokuzinzileyo kwiqondo lokushisa -200℃~ 650℃(inert environment) kunye -160℃~480℃(air environment); ichasene ne-acids ezininzi (ukugxininiswa Ngaphantsi okanye ilingana ne-35% ye-HCl, Ngaphantsi okanye ilingana ne-40% H₂SO₄), i-alkalis (i-concentration Ngaphantsi okanye ilingana ne-25% ye-NaOH), kunye ne-solvents ye-organic (methanol, i-ethylene glycol, njl.), kwaye ayikho i-inroded chemical environment.
Ukuzinza koLwakhiwo kunye nokuLungiswa lula
