Lapho i-graphite iphathwa ngamakhemikhali, ukusabela kwamakhemikhali kwenziwa kanyekanye emaphethelweni e-graphite enwetshiwe naphakathi kongqimba. Uma i-graphite ingcolile futhi iqukethe ukungcola, ukukhubazeka kwe-lattice kanye nokukhishwa kuzovela, okuholela ekwandiseni kwesifunda somkhawulo kanye nokwanda kwamasayithi asebenzayo, okuzosheshisa ukusabela konqenqemeni. Nakuba lokhu kunenzuzo ekwakhiweni kwezinhlanganisela ezinqenqemeni, kuzothinta ukwakheka kwenhlanganisela ye-graphite intercalation eyandisiwe. Futhi i-lattice egqinsiwe iyabhujiswa, okwenza i-lattice iphazamiseke futhi ingajwayelekile, ukuze isivinini nokujula kokusabalalisa kwamakhemikhali ku-interlayer kanye nokukhiqizwa kwezinhlanganisela ezijulile zokuhlanganisa kuyavinjelwa futhi kukhawulelwe, okuphinde kube nomthelela ekuthuthukisweni kwedigri yokwandisa. Ngakho-ke, kuyadingeka ukuthi okuqukethwe kokungcola kwe-graphite kufanele kube phakathi kwebanga elicacisiwe, ikakhulukazi ukungcola kwe-granular akumele kube khona, ngaphandle kwalokho izikali ze-graphite zizonqunywa ngesikhathi senqubo yokucindezela, okuzonciphisa ikhwalithi yezinto ezibunjiwe. Umhleli olandelayo we-Furuite graphite wethula ukuthi ukuhlanzeka kwezinto ezingavuthiwe zegraphite kuthinta izakhiwo zegraphite enwetshiwe:
Ubukhulu bezinhlayiyana ze-graphite nabo bunomthelela omkhulu ekukhiqizeni i-graphite eyandisiwe. Usayizi wezinhlayiyana mkhulu, indawo ethize incane, futhi indawo ehilelekile ekuphenduleni kwamakhemikhali incane ngokulinganayo. Ngokuphambene nalokho, uma inhlayiya incane, indawo yayo ethile ethile inkulu, futhi indawo yokubamba iqhaza ekuphenduleni kwamakhemikhali inkulu. Kusukela ekuhlaziyeni ubunzima bezinto zamakhemikhali ezihlaselayo, akunakugwenywa ukuthi izinhlayiya ezinkulu zizokwenza isikali segraphite sibe ukuqina, futhi izikhala phakathi kwezingqimba zizojula, ngakho-ke kuba nzima ukuthi amakhemikhali angene ungqimba ngalunye, futhi kungaphezu kwalokho. okunzima ukusakazeka ezikhaleni phakathi kwezingqimba ukuze kubangele izingqimba ezijulile. Lokhu kunethonya elikhulu kuzinga lokunwetshwa kwe-graphite enwetshiwe. Uma izinhlayiya ze-graphite zihle kakhulu, indawo ethize izoba nkulu kakhulu, futhi ukusabela konqenqemeni kuzoba okubusayo, okungahambisani nokwakhiwa kwama-intercalation compounds. Ngakho-ke, izinhlayiya ze-graphite akufanele zibe zikhulu kakhulu noma zibe zincane kakhulu.
Endaweni efanayo, ebuhlotsheni obuphakathi kokuminyana okuxekethile kanye nosayizi wezinhlayiyana zegraphite eyandisiwe eyenziwe ngegraphite enobukhulu bezinhlayiyana ezihlukene, ukuminyana okuxekethile kuncane, umphumela uba ngcono wegraphite eyandisiwe. Kodwa-ke, ekukhiqizeni kwangempela, kuboniswa ukuthi ububanzi bezinhlayiyana ze-graphite ezisetshenzisiwe kungcono kusuka ku--30 mesh kuya ku-+100 mesh, okuwumphumela omuhle kakhulu.
Umthelela wosayizi wezinhlayiyana ze-graphite ubonakala nangokuthi ukwakheka kosayizi wezinhlayiyana zezithako akufanele kube banzi kakhulu, okungukuthi, umehluko wobubanzi phakathi kwezinhlayiyana ezinkulu kanye nezinhlayiyana ezincane kakhulu akufanele zibe mkhulu kakhulu, futhi umphumela wokucubungula uzoba. kangcono uma ukwakheka kosayizi wezinhlayiyana kufana. Imikhiqizo ye-graphite ye-Furuite yonke yenziwe nge-graphite yemvelo, futhi ikhwalithi iyadingeka ngokuqinile ekukhiqizeni. Imikhiqizo ye-graphite ecutshungulwayo futhi ekhiqizwayo iye yathandwa amakhasimende amasha namadala iminyaka eminingi, futhi wamukelekile njalo ukuthi uthintane futhi uthenge!
