Nthuav graphite yog xoob thiab porous cab zoo li uas tau npaj los ntawm cov txheej txheem flakes los ntawm kev sib txuam, ntxuav dej, kom qhuav thiab kub siab nthuav dav. Cov duab nthuav dav tam sim no tuaj yeem nthuav dav 150 ~ 300 lub sij hawm hauv ntim thaum nthuav tawm kom muaj zog, yog li ntawd cov kev sib tw ntawm FLAKE graphite yog txhim kho. Ua ke, uas nce nws qhov muag muag, resilience thiab yas. Cov neeg ua plaub ntug hauv qab no yuav piav qhia rau koj ntau cov lus qhia txog kev nthuav dav ntawm kev nthuav dav graphite:
1. Granular nthuav dav graphite: me me granular expanded graphite no tsuas yog hais txog 300 mesh expandable graphite, thiab nws cov expansion ntim yog 100ml / g. Cov khoom no yog tsuas yog siv rau nplaim taws retardant txheej, thiab nws qhov kev thov yog loj heev.
2. Txhab graphite nrog kev nthuav dav kub: thawj qhov kev nthuav dav kub yog 290-300 ° C, thiab lub nthuav dav yog ≥ 230 ml / g. Hom kev nthuav dav no feem ntau yog siv rau cov nplaim taws retardant ntawm engineering plastics thiab roj hmab.
3. Tsawg qhov kev nthuav dav kub thiab qhov kub thiab txias tshaj plaws pib nthuav dav yog 80-150 ° C, thiab nthuav dav ntim mus txog 250ml / g ntawm 600 ° C.
Kev nthuav dav Graphite cov chaw tsim khoom tuaj yeem tsim cov txheej txheem txuas rau hauv cov duab hloov tau yooj yim rau kev siv raws li cov khoom siv sealing. Piv nrog cov ntaub ntawv tsoosing, yoog raws li cov cua sov muaj ntau qhov ntau ntawm -200 ℃, thiab muaj qhov nthuav tawm me me. Nws tau siv dav hauv petrochemical, machinery, metallurgy, atomic zog thiab lwm yam kev lag luam.
