Graphite yakawedzerwa chinhu chakaita sehonye chakasununguka uye chine maburi chakagadzirwa kubva kuma graphite flakes kuburikidza nemaitiro ekubatanidza, kushambidza nemvura, kuomesa uye kuwedzera tembiricha yepamusoro. Graphite yakawedzerwa inogona kukura nekukurumidza ka150 ~ 300 muhuwandu kana yaiswa patembiricha yepamusoro, ichichinja kubva pa flake kuenda pakuita sehonye, kuitira kuti chimiro chive chakasununguka, chine maburi uye chakakombama, nzvimbo yepamusoro inokura, simba repamusoro rinovandudzwa, uye simba re adsorption re flake graphite rinowedzerwa, izvo zvinowedzera kupfava kwayo, kusimba uye plasticity. Mupepeti we Furuite graphite anotevera achakutsanangurira nzira dzinoverengeka dzekuvandudza graphite yakawedzerwa:
1. Graphite yakawedzerwa negranular: Graphite diki yakawedzerwa negranular inonyanya kureva 300 mesh expandable graphite, uye vhoriyamu yayo yekuwedzera i100ml/g. Chigadzirwa ichi chinonyanya kushandiswa pakugadzira machira anodzivirira moto, uye chinodiwa zvikuru.
2. Graphite yakawedzerwa ine tembiricha yepamusoro yekutanga: tembiricha yekutanga yekuwedzera i290-300 ° C, uye vhoriyamu yekuwedzera i ≥ 230 ml/g. Rudzi urwu rwegraphite yakawedzerwa runonyanya kushandiswa pakugadzira mapurasitiki einjiniya nerabha.
3. Tembiricha yekutanga yekuwedzera yakaderera uye tembiricha yakaderera yegrafiti yakawedzera: tembiricha iyo rudzi urwu rwegrafiti yakawedzera inotanga kukura ndeye 80-150°C, uye huwandu hwekuwedzera hunosvika 250ml/g pa600°C.
Vagadziri vegrafiti vakawedzerwa vanogona kugadzira grafiti yakawedzerwa kuita graphite inochinjika kuti ishandiswe sezvinhu zvekuvhara. Kana ichienzaniswa nezvinhu zvekuvhara zvechinyakare, graphite inochinjika ine tembiricha yakakura, uye inogona kushandiswa mumhepo iri pakati pe -200℃ -450℃, uye ine thermal expansion coefficient diki. Yakashandiswa zvakanyanya mu petrochemical, michina, metallurgy, atomic energy nedzimwe nzvimbo.
