Graphite poda imhando yehupfu hwakatsetseka hwakagadzirwa nekabhoni mushure mekupisa-kupisa pyrolysis kana carbonization, uye chikamu chayo chikuru kabhoni. Graphite poda ine yakasarudzika yakaturikidzana chimiro, iri grey dema kana dema dema. Huremu hwayo hwemamorekuru ndeye 12.011.
Hunhu hwegraphite poda inogona kupfupikiswa seizvi:
1. High conductivity uye thermal conductivity: graphite powder is good conductive and thermal conductivity material, ine high thermal conductivity uye conductivity. Izvi zvinonyanya kukonzerwa nekurongeka kwakasimba uye chimiro chekabhoni maatomu mugraphite, izvo zvinoita kuti zvive nyore kuti maerekitironi uye kupisa kuite.
2. Yakanaka kemikari inertness: graphite powder ine yakanaka kugadzikana kwemakemikari uye inertness pasi pemamiriro ezvinhu akajairika, uye haaiti nezvinhu zvakawanda. Ichi ndicho chikonzero nei graphite poda ichishandiswa zvakanyanya muminda yemagetsi nemakemikari zvinhu, yakanyanya tembiricha yekudzivirira ngura, nezvimwe.
3. Iine mamwe masimba emagetsi: kana ichienzaniswa nemamwe nano-materials, graphite poda ine yakakwirira kukanganisa kupikisa, extrusion resistance uye crack resistance, iyo inogona kuwedzera mechanical properties yezvinhu kusvika pamwero wakati.
Nzira dzekugadzirira dze graphite poda dzakasiyana, uye nzira dzakajairika ndedzinotevera:
1. Pyrolysis pakupisa kwepamusoro: kupisa kwechisikigo graphite kana kemikari yakagadzirwa graphite crystal kusvika kune tembiricha yepamusoro (pamusoro pe2000 ℃) kuti iparadze kuita graphite upfu.
2. High-temperature carbonization method: graphite powder inowanikwa nemakemikari reaction ye graphite nezvinhu zvakasvibirira zvine maitiro akaiswa akafanana negraphite. Zvinoenderana neyakasiyana mbishi, inogona kukamurwa kuita dzakasiyana nzira dzekugadzirira, senge vapor kemikari vapor deposition, pyrolysis uye carbonization.
3. Mechanical method: kuburikidza nemagetsi ekukuya uye kuongorora maitiro, magirafu echisikigo kana kuti synthetic graphite zvinhu zvinogadziriswa kuti zviwane graphite powder.
Nzira dzakasiyana dzekugadzirira dzine maitiro akasiyana pahutano, kuchena uye morphology ye graphite powder. Mukushanda kwekushanda, nzira dzekugadzirira dzakakodzera dzinoda kusarudzwa maererano nezvinodiwa zvakasiyana.
1. Zvigadzirwa zvemagetsi nemakemikari: graphite poda inogona kugadzirirwa kuita conductive uye thermal conductive polymer composites, iyo inoshandiswa mumagetsi emagetsi, mabhatiri, conductive ingi uye mamwe minda. Semuenzaniso, mumagetsi emagetsi, graphite poda inogona kuwedzera kufambiswa kwezvinhu, kuvandudza mashandiro emagetsi e electrode, uye kuwedzera hupenyu hwebasa rebhatiri.
2. Zvishongedzo zvekupfekedza: graphite poda inogona kushandiswa kugadzira machira akasiyana-siyana, senge anti-corrosion coating, thermal conductivity coating, electromagnetic shielding coating, etc. Muminda yemotokari, ndege, kuvaka, nezvimwewo, machira akagadzirwa. ine graphite poda inogona kuvandudza ultraviolet kuramba uye corrosion kuramba kwezvinhu.
3. Catalyst: Graphite powder inogona kushandiswa pakugadzirisa kwekugadzirisa, uye inoshandiswa zvakanyanya mukugadzirwa kwehupenyu, kugadzirwa kwemakemikari nemimwe minda. Semuenzaniso, mu hydrogenation yemafuta emiriwo, graphite poda mushure mekurapa inogona kushandiswa sechigadziriso chekuvandudza maitiro ekusarudza uye goho.
4. Ceramic zvinhu: Mukugadzira zvinhu zveceramic, graphite powder inogona kuvandudza simba rayo remagetsi uye zvimwe zvinhu kuburikidza nekusimbisa simba. Kunyanya mune cermets uye porous ceramics, graphite poda inoshandiswa zvakanyanya.
