Pamene graphite ndi mankhwala ankachitira, mankhwala anachita ikuchitika imodzi m'mphepete mwa kukodzedwa graphite ndi pakati wosanjikiza. Ngati graphite ndi yodetsedwa ndipo imakhala ndi zonyansa, zofooka za lattice ndi dislocation zidzawoneka, zomwe zimapangitsa kuti chigawo cha m'mphepete chiwonjezeke ndi kuwonjezeka kwa malo ogwira ntchito, zomwe zidzafulumizitsa zomwe zimachitika. Ngakhale kuti izi ndizopindulitsa pakupanga mapangidwe a m'mphepete, zidzakhudza kupanga mapangidwe owonjezera a graphite intercalation. Ndipo ma latisi wosanjikiza amawonongedwa, zomwe zimapangitsa kuti ma latisi asokonezeke komanso osakhazikika, kotero kuti liwiro ndi kuya kwa kufalikira kwa mankhwala ku interlayer ndi m'badwo wazinthu zakuya za intercalation zimalephereka komanso zimalepheretsa, zomwe zimakhudzanso kuwongolera kwa digiri. Choncho, pamafunika kuti zonyansa za graphite zikhale mkati mwazomwe zimatchulidwa, makamaka zonyansa za granular siziyenera kukhalapo, mwinamwake mamba a graphite adzadulidwa panthawi yokakamiza, zomwe zidzachepetse ubwino wa zipangizo zopangidwira. Mkonzi wotsatira wa Furuite graphite akuwonetsa kuti kuyera kwa zida za graphite kumakhudzanso zomwe graphite yowonjezereka:
The tinthu kukula kwa graphite alinso kwambiri chikoka pa ulimi kukodzedwa graphite. Kukula kwa tinthu ndi kwakukulu, malo enieniwo ndi ochepa, ndipo dera lomwe limakhudzidwa ndi mankhwala ndilochepa. M'malo mwake, ngati tinthu tating'onoting'ono, malo ake enieni ndi aakulu, ndipo malo ochitira nawo mankhwala ndi aakulu. Kuchokera pakuwunika kwazovuta za mankhwala omwe akuwukira, sikungapeweke kuti tinthu tating'onoting'ono tipangitse masikelo a graphite kukhala wandiweyani, ndipo mipata pakati pa zigawo idzakhala yakuya, kotero zimakhala zovuta kuti mankhwala alowe mugawo lililonse, ndipo ndizochulukirapo. zovuta kufalikira mu mipata pakati pa zigawo kuti apangitse zigawo zakuya. Izi zimakhudza kwambiri kukula kwa graphite yowonjezereka. Ngati ma graphite particles ndi abwino kwambiri, malo enieniwo adzakhala aakulu kwambiri, ndipo m'mphepete mwake mudzakhala wamkulu, zomwe sizikugwirizana ndi mapangidwe a intercalation. Chifukwa chake, tinthu tating'ono ta graphite siyenera kukhala zazikulu kapena zazing'ono.
M'malo omwewo, mu ubale pakati lotayirira kachulukidwe ndi tinthu kukula kukodzedwa graphite zopangidwa graphite ndi kukula kwake tinthu, ang'onoang'ono lotayirira kachulukidwe, ndi bwino zotsatira za kukodzedwa graphite. Komabe, kupanga kwenikweni, zikuwonetsedwa kuti tinthu tating'onoting'ono ta graphite yomwe imagwiritsidwa ntchito makamaka kuchokera -30 mauna mpaka +100 mauna, omwe ndi abwino kwambiri.
Chikoka cha kukula kwa tinthu tating'onoting'ono ta graphite kumawonekeranso kuti kukula kwa tinthu tating'onoting'ono kuyenera kukhala kotakata kwambiri, ndiko kuti, kusiyana kwakukulu pakati pa tinthu tating'onoting'ono ndi tinthu tating'onoting'ono kuyenera kukhala kwakukulu kwambiri, ndipo zotsatira zake zitha kukhala. bwino ngati tinthu kukula zikuchokera yunifolomu. Zogulitsa za Furuite graphite zonse zimapangidwa ndi graphite yachilengedwe, ndipo mtunduwo umafunikira kwambiri popanga. Zogulitsa za graphite zomwe zimakonzedwa ndikupangidwa zakondedwa ndi makasitomala atsopano ndi akale kwa zaka zambiri, ndipo ndinu olandiridwa nthawi zonse kuti mufunsire ndikugula!
