Kugawa mapepala a graphite

Pepala la graphite limadutsa mu njira zingapo zowonjezera monga graphite ya phosphorous yokhala ndi mpweya wambiri, mankhwala, kukulitsa kutentha ndi kuwotcha. Lili ndi kukana kutentha kwambiri, kutentha koyendetsa, kusinthasintha, kulimba komanso magwiridwe antchito abwino kwambiri otsekera. Pepala la graphite lili ndi makhalidwe abwino kwambiri. Malinga ndi momwe limagwiritsidwira ntchito, lingagawidwe m'magulu otsekera.pepala la graphite, pepala la graphite loyendetsa kutentha ndi pepala la graphite loyendetsa.
1. Pepala la graphite lotsekera
Yagwiritsidwa ntchito kwambiri m'magetsi, makampani opanga mankhwala, zida, makina ndi mafakitale ena. Ikhoza kulowa m'malo mwa zomatira zachikhalidwe monga rabara ndi asbestos ndikugwiritsidwa ntchito ngati zomatira zamphamvu komanso zosasinthasintha za makina, mapaipi, mapampu ndi ma valve.
2. Pepala la graphite lotenthetsera kutentha
Pepala la graphite lothandizira kutentha lili ndi mphamvu yabwino kwambiri yoyendetsera kutentha komanso mphamvu yotaya kutentha. Limagwiritsidwa ntchito makamaka m'mafoni am'manja, ma laputopu ndi zinthu zina zamagetsi.
3. Pepala la graphite loyendetsa
Amagwiritsidwa ntchito kwambiri popanga ndi kukonza zinthu zosiyanasiyana zoyendetsera magetsi.

Mfundo ndi kugwiritsa ntchito pepala la graphite m'mafakitale

Mfundo yoyendetsera kutentha kwa pepala la graphite ndi yakuti kutentha kwambiri ndi kutentha zimapangitsa kutentha mofanana m'mbali zonse ziwiri kudzera pamwamba pa pepala la graphite. Pepala la graphite limatha kuyamwa gawo la kutentha ndikuchotsa kutentha kudzera mu kuyendetsa kutentha pamwamba pa pepala la graphite, komwe kumachita gawo logawa kutentha. Kuyendetsa kutentha kopingasa kwa pepala la graphite nthawi zambiri kumakhala pakati pa w / mk ndipo kuyendetsa kutentha koyima kuli pakati pa 10-20w / mK, Kuyendetsa kutentha kumakhala kofanana ndi mtengo wa pepala la graphite.

Poyerekeza ndi zipangizo zachitsulo zachikhalidwe, kutentha kwa pepala la graphite ndi kowirikiza katatu mpaka kasanu kuposa kwa mkuwa ndi aluminiyamu.Pepala lopyapyala kwambiri la graphiteKawirikawiri amagwiritsidwa ntchito popereka kutentha kwa zida zamagetsi. Graphite yopyapyala kwambiri imakhala ndi mphamvu yotsika ya kutentha, 40% yotsika kuposa aluminiyamu ndi 20% yotsika kuposa mkuwa. Pepala la graphite likhoza kudulidwa m'mawonekedwe osiyanasiyana, ndipo pepala la graphite lopereka kutentha lingagwiritsidwe ntchito pochotsa kutentha kwa zida zamagetsi.
