Graphite yakakamurwa kuita girafu yechisikigo uye yekugadzira graphite. Vanhu vazhinji vanoziva asi havazivi kuti vangazvisiyanisa sei. Ndeupi musiyano uripo pakati pazvo? Mupepeti anotevera achakuudza nzira yekusiyanisa pakati pezviviri:
1. Crystal chimiro
Natural graphite: Kukura kwekristaro kunenge kwakazara, dhigirii ye graphitization yeflake graphite inopfuura 98%, uye dhigirii re graphitization yemasikirwo microcrystalline graphite kazhinji iri pasi pe93%.
Artificial graphite: Iyo dhigirii yekukura kwekristaro inoenderana neyakabikwa uye tembiricha yekurapa kupisa. Kazhinji kutaura, kukwira kwekushisa kwekushisa kwekushisa, kunowedzera dhigirii ye graphitization. Parizvino, dhigirii regraphitization yeyakagadzirwa graphite inogadzirwa muindasitiri kazhinji isingasviki 90%.
2. Chimiro chesangano
Natural flake graphite: Ikristaro imwe chete ine chimiro chakareruka uye inongove nekukanganisa kwekristaro (senge mapoinzi defects, dislocations, stacking kukanganisa, nezvimwewo), uye inoratidza anisotropic maitiro pane macroscopic level. Zviyo zvechisikigo microcrystalline graphite zviduku, zviyo hazvina kurongeka, uye kune pores mushure mokunge tsvina yabviswa, ichiratidza isotropy pane macroscopic level.
Artificial graphite: Inogona kutariswa seyakawanda-chikamu zvinhu, zvinosanganisira graphite chikamu chakashandurwa kubva kucarbonaceous particles senge petroleum coke kana pitch coke, graphite chikamu chakashandurwa kubva marasha tar binder yakaputirwa nezvikamu, kuunganidzwa kwezvikamu kana marasha tara. Mapores akaumbwa nebhainda mushure mekupisa kupisa, nezvimwe.
3. Chimiro chemuviri
Natural graphite: inowanzovapo mumhando yehupfu uye inogona kushandiswa yoga, asi inowanzoshandiswa pamwe chete nezvimwe zvinhu.
Artificial graphite: Kune akawanda mafomu, anosanganisira hupfu, faibha uye block, nepo artificial graphite mupfungwa nhete inowanzovharika, inoda kugadziriswa kuita imwe chimiro kana ichishandiswa.
4. Muviri uye makemikari zvinhu
Panyaya yezvimiro zvemuviri uye zvemakemikari, magirafu echisikigo uye artificial graphite ane zvese zvakafanana uye mutsauko mukuita. Semuyenzaniso, ese ari maviri echisikigo graphite uye artificial graphite ndiwo akanaka conductor ekupisa nemagetsi, asi kune graphite hupfu hwekuchena kwakafanana uye saizi yechikamu, natural flake graphite ine yakanakisa kupisa kupisa kuita uye magetsi conductivity, inoteverwa neakasikwa microcrystalline graphite uye artificial graphite. . yakaderera. Graphite ine lubricity yakanaka uye mamwe mapurasitiki. Iko kukwidziridzwa kwekristaro kwechisikigo flake graphite kunenge kuzere, iyo friction coefficient idiki, lubricity ndiyo yakanyanya kunaka, uye plastiki ndiyo yepamusoro, inoteverwa nedense crystalline graphite uye cryptocrystalline graphite, ichiteverwa neyakagadzirwa graphite. varombo.
Qingdao Furuite Graphite inonyanya kubatanidzwa mune yakachena yakasikwa graphite poda, graphite bepa, graphite mukaka uye zvimwe zvigadzirwa zvegraphite. Iyo kambani inokoshesa zvakanyanya kuchikwereti kuti ive nechokwadi chemhando yepamusoro yezvigadzirwa. Vatengi vanogamuchirwa kutibata nesu.
