Izici zokunwetshwa ze-graphite flake ezinwebekayo zihlukile kwamanye ama-ejenti wokunweba. Lapho ishiselwa ezingeni elithile lokushisa, i-graphite enwebekayo iqala ukwanda ngenxa yokubola kwezinhlanganisela ezivaleleke ku-interlayer lattice, okubizwa ngokuthi izinga lokushisa lokuqala lokunwetshwa. Inwebeka ngokuphelele ku-1000 ℃ futhi ifinyelela kumthamo wayo omkhulu. Umthamo owandisiwe ungafinyelela izikhathi ezingaphezu kuka-200 zevolumu yokuqala, futhi igraphite eyandisiwe ibizwa ngokuthi i-graphite enwetshiwe noma i-graphite worm, eshintshayo ukusuka ekumisekeni kwe-scaly yasekuqaleni ukuya ekumiseni kwesikelemu ngokuminyana okuphansi, kwakha ungqimba oluhle kakhulu lokufakwa kwe-thermal. I-graphite eyandisiwe ayiwona nje umthombo wekhabhoni ohlelweni lokunweba, kodwa futhi ungqimba lokufakwa kwe-insulation, olungavala ukushisa ngokuphumelelayo. Inezici zezinga eliphansi lokukhishwa kokushisa, ukulahlekelwa okuncane kwenqwaba kanye nentuthu encane ekhiqizwe emlilweni. Ngakho yiziphi izici ze-graphite enwebekayo ngemva kokushiswa ibe yi-graphite enwetshiwe? Nangu umhleli ukuze asethule ngokuningiliziwe:
1, ukumelana nengcindezi eqinile, ukuguquguquka, ipulasitiki kanye nokuzigcoba;
2. Ukumelana nokushisa okuphezulu kakhulu nokuphansi, ukumelana nokugqwala kanye nokumelana nemisebe;
3. Izici eziqinile zokuzamazama komhlaba;
4. I-conductivity ephezulu kakhulu;
5. Izici eziqinile zokulwa nokuguga kanye nokuphikisana nokuhlanekezela;
6. Ingakwazi ukumelana nokuncibilika nokungena kwezinsimbi ezihlukahlukene;
7. Okungeyona ubuthi, ngaphandle kwanoma iyiphi i-carcinogen, futhi akukho monakalo emvelweni.
Ukunwetshwa kwe-graphite enwebekayo kunganciphisa ukuguquguquka okushisayo kwento futhi kufinyelele umphumela we-flame retardant. Uma i-graphite enwebekayo yengezwe ngokuqondile, isakhiwo se-carbon layer esakhiwe ngemva kokusha asiqinile. Ngakho-ke, ekukhiqizeni kwezimboni, i-graphite enwebekayo kufanele yengezwe, enomphumela omuhle we-flame retardant enqubweni yokuguqulwa ibe i-graphite eyandisiwe lapho ishisa.
