Graphite ntawv, raws li cov khoom lag luam tseem ceeb, ua si yog lub luag haujlwm me me hauv ntau daim teb ua tsaug rau nws cov khoom siv lub cev thiab tshuaj lom neeg zoo. Tsim ntawm carbon thiab ua tiav los ntawm high- kev kho kom haum, corrosion kev kho mob, muaj hluav taws xob siab, thiab lub zog zoo heev. Nws yog dav siv nyob rau hauv kev lag luam xws li metallurgy, tshuaj lom neeg, khoom siv hluav taws xob, thiab lub zog tshiab.
Graphite ntawv lub siab - kub kuj yog ib qho ntawm nws qhov tseem ceeb tshaj plaws. Txawm nyob ntawm qhov kub tshaj 3000 degree, graphite tswj hwm lub cev ruaj khov thiab tiv taus deformation lossis oxidation. Cov cuab yeej no ua rau nws muaj cov khoom siv tsis tseem ceeb hauv kev lag luam metallurgical, qhov twg nws feem ntau siv nyob rau hauv kev tsim cov tshuab hluav taws xob siab, electstodes, thiab crucibles, thiab crucaides. Piv txwv li, thaum cov hluav taws xob steelmaking tuaj yeem tiv taus ntau dua tam sim no tuab tam sim no, kom ua haujlwm ruaj khov ntawm hluav taws xob arc.
Graphite daim ntawv tseem ua rau pom kev zam tshwj xeeb corrosion. Vim yog cov tshuaj ruaj khov ntawm carbon, graphite yog resistant rau acids, alkalis, thiab cov kuab tshuaj organic. Yog li ntawd, nws yog dav siv hauv kev tsim cov tshuaj lom neeg, piv txwv li kev tsim cov tshuaj corrosion {}} ion resistant cov khoom siv, ntsaws ruaj ruaj. Nyob rau hauv cov txheej txheem corrosive heev, graphite daim ntawv tuaj yeem ua tau zoo ntev cov cuab yeej thiab txo tus nqi kho.
Graphite cov ntawv 'siab hluav taws xob thiab thermal ua lawv cov ntawv thov tseem ceeb hauv cov khoom siv hluav taws xob thiab lub zog hluav taws xob. Hauv kev lag luam roj teeb, hloov tau dav siv los ua cov khoom tsis zoo electrode rau lithium {{} ion roj teeb vim nws lub zog ruaj khov thiab tawm mus raws kev ua haujlwm. Graphite cov ntawv tseem siv nyob rau hauv kev tsim cov phiaj hlau bipolar rau roj hlwb, txhim kho lub roj teeb hluav taws xob. Nyob rau hauv cov semiconductor kev tsim khoom, graphite, vim nws cov khoom muaj kuab paug tsis muaj kuab paug, feem ntau siv los ua cov khoom siv thauj khoom thaum muaj kev sib tw.
Ntxiv rau cov ntawv thov no, cov ntawv txheeb xyuas kuj tseem siv los ua cov khoom siv sealing thiab hnav {{{} {{{1} lubricating zog. Hauv Aerospace, graphite sib xyaw, vim lawv lub teeb ci thiab siab {{{- qhov kub txheej txheem.
Hauv ntej, graphite cov ntawv, nrog lawv cov khoom muaj npe, ua si ib lub luag haujlwm tseem ceeb hauv kev lag luam niaj hnub. Nrog kev txhim kho thev naus laus zis, daim ntawv thov tau txais cov ntaub ntawv graphite yuav txuas ntxiv mus rau lwm tus, thiab siab} {}}}}} yuav tshawb xyuas qhov twg. Nyob rau yav tom ntej, graphite daim ntawv yuav txuas ntxiv ua cov khoom tseem ceeb, tsav kev siv thev naus laus zis tshiab thiab kev tsim kho thoob plaws ntau yam lag luam.
