Graphite kurongedza, sechinhu chakakosha chekuisa chisimbiso, chinoshandiswa zvakanyanya mundima yeindasitiri yekutenderera shafts, zvinhu zvinodzosera, uye static yekuisa chisimbiso maapplication. Nheyo yekushanda kwayo yakavakirwa pane yakasarudzika yemuviri uye makemikari zvimiro zvegraphite. Kuburikidza nekugadzirwa kwemaitiro uye kuchinjika kumamiriro ekushanda, inowana kuenzana pakati pekuisa chisimbiso kwakanaka uye kushomeka kwekusapfeka. Ichi chinyorwa chichakurukura nezvezvinhu zve graphite kurongedza, nzira yekuisa chisimbiso, zvinhu zvinokanganisa mamiriro ekushanda, uye akajairwa maficha ekushandisa.
Material Properties uye Basic Mabasa eGraphite Packing
Iyo yakakosha zvinhu zve graphite packing inowanzo wedzerwa graphite kana inoshanduka graphite. Inogadzirwa nemakemikari kurapa natural flake graphite (senge intercalation) uye wozoiwedzera pakupisa kwakanyanya. Kuita uku kunonetesa kubatana pakati pema graphite layers, kuumba akawedzera graphite worm ane yakasununguka uye porous chimiro. Makonye aya anobva atsindirwa kana kuumbwa kuita zvindori zvekutakura kana tambo dzine imwe nhanho yekuchinjika uye kusimba.
Hunhu hwakakosha hwekuita hunosanganisira:
1. Kuzvizora-kuzora: Graphite crystal layers inotsvedza zviri nyore, zvichiita kuti pave nekukweshana kwakaderera (kazhinji 0.05-0.15), kuderedza kusakara kwepasi pasina kudiwa kwemafuta ekuwedzera.
2. Yakakwira{1}}kuramba tembiricha: Girafiti yakachena inokwanisa kumira tembiricha inoramba ichishanda inodarika 450 madhigirii (kusvika 800 madhigirii nekurapwa kwakakosha) uye inochengetedza kugadzikana kwechimiro kunyangwe kune tembiricha yepamusoro.
3. Chemical inertness: Graphite inert kune akawanda acids, mabhesi, uye organic solvents, soluble chete mune yakasimba oxidizing media (yakadai seconcentrated sulfuric acid uye nitric acid), ichiita kuti ive yakakodzera kune corrosive kushanda mamiriro.
4. Compressibility uye kusimba: Nekudzora kudzvanya (kazhinji 20% -30%), iyo filler inogona kukanganisa radially pasi peaxial pressure, ichizadza chisimbiso chivharo uye kugadzira yekutanga chisimbiso simba.
