Dab tsi yog qhov zoo ntawm cov ntawv hloov pauv graphite ua cov khoom sib khi?

    Graphite ntawvyog tam sim no ntau thiab ntau lug siv nyob rau hauv high-tech electronics kev lag luam. Nrog rau kev txhim kho ntawm kev ua lag luam, graphite ntawv tau pom cov ntawv thov tshiab, ib yam lisaj zawg zog graphite ntawvtuaj yeem siv los ua cov ntaub ntawv sealing. Yog li dab tsi yog qhov zoo ntawm cov ntawv hloov pauv graphite li cov khoom sib khi? Peb yuav muab koj cov ncauj lus kom ntxaws tsom xam:
Tam sim no, cov khoom lag luam hloov pauv graphite feem ntau suav nrog cov nplhaib ntim khoom,gasket, cov khoom ntim dav dav, cov phaj sib xyaw xuas nrig ntaus los ntawm cov phaj hlau, ntau yam gaskets ua los ntawm laminated (bonded) composite phaj, thiab lwm yam. lawv tau siv dav hauv petrochemical, machinery, metallurgy, atomic zog, hluav taws xob fais fab thiab lwm yam hauj lwm, nrog rau zoo corrosion kuj, kub tsis kam, shrinkage thiab rov qab zoo heev maj maj kev nyuaj siab thiab nws tus kheej-lubricating zog.
Cov khoom sib khi tsoos yog tsim los ntawm asbestos, roj hmab, cellulose thiab lawv cov khoom sib xyaw. Txawm li cas los xij, nrog kev txhim kho ntawm kev lag luam, cov ntawv hloov pauv graphite raws li cov ntaub ntawv sib khi tau pib siv dav. Qhov ntsuas kub muaj nyob ntawm cov ntawv hloov pauv graphite yog qhov dav, uas tuaj yeem ncav cuag 200 ~ 450 ℃ hauv huab cua thiab 3000 ℃ hauv lub tshuab nqus tsev lossis txo qhov cua, thiab cov coefficient ntawm thermal expansion me me. Nws tsis brittleness thiab tawg ntawm qhov kub thiab txias thiab soften ntawm kub. Cov no yog cov xwm txheej uas cov khoom siv sealing ib txwm tsis muaj. Yog li ntawd, cov ntawv hloov pauv graphite tau piav qhia tias yog "kev sib khi huab tais".
