Expanded graphite yog ib qho xoob thiab ntxeem tau zoo li cov khoom uas tau npaj los ntawm graphite flakes los ntawm cov txheej txheem ntawm intercalation, dej ntxuav, ziab thiab kub expansion. Expanded graphite tuaj yeem nthuav dav 150 ~ 300 zaug hauv ntim thaum raug kub, hloov los ntawm flake mus rau worm-zoo li, kom cov qauv yog xoob, ntxeem tau thiab nkhaus, thaj chaw saum npoo yog loj, lub zog saum npoo yog txhim kho, thiab adsorption quab yuam ntawm flake graphite yog txhim kho. ua ke, uas ua rau nws softness, resilience thiab plasticity. Cov nram qab no Furuite graphite editor yuav piav qhia rau koj ob peb lub ntsiab kev loj hlob ntawm nthuav graphite:
1. Granular expandable graphite: Me me granular expanded graphite feem ntau yog hais txog 300 mesh expandable graphite, thiab nws expansion ntim yog 100ml / g. Cov khoom no tsuas yog siv rau cov nplaim hluav taws xob coatings, thiab nws qhov kev thov yog loj heev.
2. Expanded graphite nrog siab pib expansion kub: thawj expansion kub yog 290-300 ° C, thiab expansion ntim yog ≥ 230 ml / g. Hom kev nthuav dav graphite no tsuas yog siv rau cov nplaim hluav taws xob ntawm engineering plastics thiab roj hmab.
3. Tsawg pib nthuav dav kub thiab tsis tshua muaj kub nthuav dav graphite: qhov kub ntawm qhov no hom ntawm graphite nthuav dav yog 80-150 ° C, thiab qhov ntim nthuav dav mus txog 250ml / g ntawm 600 ° C.
Expanded graphite manufacturers tuaj yeem ua cov graphite nthuav dav rau hauv graphite hloov tau siv los ua cov ntaub ntawv sib khi. Piv nrog rau cov khoom sib khi ib txwm muaj, cov graphite hloov tau muaj qhov dav ntawm qhov kub thiab txias, thiab tuaj yeem siv rau hauv huab cua hauv thaj tsam ntawm -200 ℃ -450 ℃, thiab muaj cov thermal expansion coefficient me me. Nws tau dav siv hauv petrochemical, machinery, metallurgy, atomic zog thiab lwm yam lag luam.
