Graphite paper classification

Graphite paper classification

Graphite ntawv hla dhau los ntawm cov txheej txheem ntxiv xws li cov pa roj carbon phosphorus siab graphite, tshuaj kho mob, kub kub expansion dov thiab roasting. Nws muaj qhov kub thiab txias tsis kam, thermal conduction, yooj, resilience thiab sealing zoo heev. Graphite ntawv muaj cov yam ntxwv zoo heev. Raws li nws daim ntawv thov, nws tuaj yeem muab faib ua sealinggraphite ntawv, thermal conductive graphite ntawv thiab conductive graphite ntawv.
1. Graphite ntawv rau sealing
Nws tau siv dav hauv hluav taws xob, tshuaj lom neeg kev lag luam, ntsuas, tshuab thiab lwm yam lag luam. Nws tuaj yeem hloov cov ntsaws ruaj ruaj xws li roj hmab thiab asbestos thiab siv los ua cov ntsaws ruaj ruaj thiab zoo li qub ntawm cov tshuab, kav dej, twj thiab li qub.
2. Thaum tshav kub kub ua graphite ntawv
Thermal conductive graphite ntawv muaj cov thermal conductivity zoo heev thiab kev ua haujlwm kub dissipation. Nws yog tsuas yog siv hauv xov tooj ntawm tes, laptops thiab lwm yam khoom siv hluav taws xob.
3. Conductive graphite ntawv
Nws yog feem ntau siv rau hauv kev tsim khoom thiab kev ua haujlwm ntawm ntau yam khoom siv hluav taws xob.

Txoj cai thiab kev siv ntawm graphite ntawv

Lub hauv paus ntsiab lus ntawm thermal conduction ntawm graphite ntawv yog qhov kub thiab txias ua cua sov sib npaug ntawm ob qho kev qhia los ntawm cov ntawv graphite. Graphite daim ntawv tuaj yeem nqus tau ib feem ntawm cov cua sov thiab tshem tawm cov cua sov los ntawm cov cua sov ua rau ntawm daim ntawv graphite, uas ua lub luag haujlwm ntawm cov cua sov dissipation. Kab rov tav thermal conductivity ntawm graphite ntawv feem ntau yog nruab nrab ntawm w / mk thiab ntsug thermal conductivity ntawm 10-20w / mK, thermal conductivity yog ncaj qha proportional rau tus nqi ntawm graphite ntawv.

Piv nrog rau cov khoom siv hlau tsoos, cov thermal conductivity ntawm graphite ntawv yog 3 ~ 5 npaug ntawm tooj liab thiab txhuas.Ultra nyias graphite ntawvfeem ntau yog siv rau kev siv hluav taws xob siv hluav taws xob. Ultra nyias graphite muaj thermal tsis kam, 40% qis dua txhuas thiab 20% qis dua tooj liab. Graphite daim ntawv tuaj yeem raug txiav rau hauv ntau yam duab, thiab cov ntawv hluav taws xob graphite tuaj yeem siv rau cov cua sov dissipation ntawm cov khoom siv hluav taws xob.
