Iimpawu zeebheringi zegrafiti

Iimpawu zeebheringi zegrafiti

1. Uzinzo oluhle lweekhemikhali
I-Graphite yinto ezinzileyo ngokweekhemikhali, kwaye ukuzinza kwayo ngokweekhemikhali akungaphantsi koko kweentsimbi ezixabisekileyo. Ukunyibilika kwayo kwisilivere enyibilikisiweyo yi-0.001% - 0.002% kuphela.IgrafayithiAyinyibiliki kwizinto eziphilayo okanye ezingaphiliyo. Ayidli kwaye ayinyibiliki kwiiasidi ezininzi, iisiseko kunye neetyuwa.
2. Ukumelana nobushushu obuphezulu kokuthwala i-graphite
Ngovavanyo, ubushushu benkonzo yeebheringi zekhabhoni eziqhelekileyo bunokufikelela kwi-350 ℃; Ibheringi yegrafiti yesinyithi nayo ifikelela kwi-350 ℃; Ibheringi yegrafiti ye-electrochemical inokufikelela kwi-450-500 ℃ (phantsi komthwalo omncinci), iipropati zayo zomzimba nezoomatshini azitshintshi, kwaye ubushushu benkonzo yayo bunokufikelela kwi-1000 ℃ phantsi kwe-vacuum okanye umoya okhuselayo.
3. Ukusebenza kakuhle kokuzithambisa
Ukuthwala iGraphiteinokusebenza kakuhle kokuzithambisa ngenxa yezizathu ezibini. Esinye sezizathu kukuba iiathom zekhabhoni kwi-graphite lattice zicwangciswe kwiplane nganye ngendlela eqhelekileyo enesiqingatha. Umgama phakathi kweeathom usondelelene, oyi-0.142 nm, ngelixa umgama phakathi kweeplane uyi-0.335 nm, kwaye zijijekile ukusuka kwenye kwenye kwicala elinye. Iplane yesithathu iphinda indawo yeplane yokuqala, iplane yesine iphinda indawo yeplane yesibini, njalo njalo. Kwiplane nganye, amandla okubopha phakathi kweeathom zekhabhoni anamandla kakhulu, ngelixa umgama phakathi kweeplane mkhulu, kwaye amandla evan der Waals phakathi kwazo abuthathaka kakhulu, ngoko ke kulula ukuhamba nokutyibilika phakathi kweeleya, nto leyo ebangela ukuba izinto zegrafiti zibe neempawu zokuzithambisa.
Isizathu sesibini kukuba izinto zegrafiti zinamathela kakhulu kwizinto ezininzi zesinyithi, ngoko ke igrafiti ekhutshiweyo inokunamathela ngokulula kumphezulu wesinyithi xa isilwa ngesinyithi, yenze umalekoifilimu yegrafayithi, nto leyo eba kukungqubana phakathi kwegraphite kunye negraphite, ngaloo ndlela kunciphisa kakhulu ukuguguleka kunye nokulingana kokungqubana, Esi sisizathu sokuba iibheringi ze-carbon graphite zisebenza kakuhle kakhulu ekuzithambiseni kunye nokusebenza kokuthintela ukungqubana.
4. Ezinye iimpawu zegrafiti
Xa kuthelekiswa nezinye iibheringi,iibheringi zegrafayithiikwanayo ne-thermal conductivity ephezulu, i-coefficient ephantsi yokwandiswa okuthe tye, ukupholisa ngokukhawuleza kunye nokumelana nobushushu njalo njalo.
