Graphite yakakamurwa kuita graphite yechisikigo uye graphite yakagadzirwa. Vanhu vazhinji vanoiziva asi havazivi kuti vanoisiyanisa sei. Ndeipi misiyano iri pakati payo? Mupepeti anotevera achakuudza kuti ungasiyanisa sei zviviri izvi:
1. Chimiro chekristaro
Graphite yechisikigo: Kukura kwekristaro kwakazara, mwero wegraphitization ye flake graphite inopfuura 98%, uye mwero wegraphitization ye natural microcrystalline graphite inowanzo kuve pasi pe93%.
Graphite yekugadzira: Mwero wekukura kwekristaro unoenderana nezvinhu zvakabikwa uye tembiricha yekurapa kupisa. Kazhinji, tembiricha yekurapa kupisa yakakwira, mwero wegraphitization wakakwira. Parizvino, mwero wegraphitization yegraphite yekugadzira inogadzirwa muindasitiri unowanzova pasi pe90%.
2. Maumbirwo esangano
Graphite yechisikigo: Ikristaro imwe chete ine chimiro chakareruka uye ine zvikanganiso zvekristaro chete (zvakadai sekukanganisa kwemapoinzi, kupatsanurwa, kukanganisa kwekuisa zvinhu muzvikamu, nezvimwewo), uye inoratidza hunhu hweanisotropic padanho remacroscopic. Tsanga dzegraphite yechisikigo idiki, tsanga dzakarongwa zvisina kurongeka, uye kune maburi mushure mekunge tsvina yabviswa, zvichiratidza isotropy padanho remacroscopic.
Graphite yekugadzira: Inogona kuonekwa sechinhu chine zvikamu zvakawanda, kusanganisira graphite phase yakashandurwa kubva muzvimedu zvecarbonaceous zvakaita sepetroleum coke kana pitch coke, graphite phase yakashandurwa kubva mucoal tar binder yakaputirwa pazvimedu, particle accumulation kana coal tar pitch. Maburi anoumbwa nebinder mushure mekupisa, nezvimwewo.
3. Chimiro chemuviri
Graphite yechisikigo: inowanzo kuwanikwa muchimiro chehupfu uye inogona kushandiswa yoga, asi inowanzo shandiswa pamwe chete nezvimwe zvinhu.
Graphite yekugadzira: Kune marudzi akawanda, anosanganisira hupfu, faibha uye bhuroko, nepo giraphite yekugadzira mupfungwa yakamanikana inowanzova bhuroko, iro rinoda kugadziriswa kuita chimiro chakati kana richishandiswa.
4. Hunhu hwemuviri nemakemikari
Panyaya yehunhu hwemuviri nemakemikari, graphite yechisikigo negraphite yekugadzira zvine zvakafanana uye zvakasiyana pakushanda. Semuenzaniso, graphite yechisikigo negraphite yekugadzira zvinhu zvinofambisa kupisa nemagetsi zvakanaka, asi kune hupfu hwegraphite hwakafanana uye saizi yezvikamu, graphite yechisikigo ine simba rakanakisa rekufambisa kupisa uye conductivity yemagetsi, ichiteverwa negrafiti yechisikigo yemicrocrystalline negraphite yekugadzira zvinhu. Graphite ine lubricity yakanaka uye plasticity yakati. Kukura kwekristaro kwegrafiti yechisikigo yeflake kwakazara, coefficient yekukweshana idiki, lubricity ndiyo yakanakisa, uye plasticity ndiyo yepamusoro, ichiteverwa negrafiti yakakora yecrystalline necryptocrystalline graphite, ichiteverwa negrafiti yekugadzira zvinhu.
Qingdao Furuite Graphite inonyanya kushandiswa mukugadzira hupfu hwegraphite hwechisikigo, bepa regraphite, mukaka wegraphite nezvimwe zvigadzirwa zvegraphite. Kambani iyi inonyanya kukoshesa zvikwereti kuti ive nechokwadi chekuti zvigadzirwa zvemhando yepamusoro. Vatengi vanogamuchirwa kutibata nesu.
