Imbonakalo yegrafiti izise uncedo olukhulu ebomini bethu. Namhlanje, siza kujonga iintlobo zegrafiti, igrafiti yomhlaba kunye negrafiti ethambileyo. Emva kophando oluninzi nokusetyenziswa, ezi ntlobo zimbini zezinto zegrafiti zixabiseke kakhulu. Apha, uMhleli weGrafiti waseQingdao Furuite ukuxelela ngomahluko phakathi kwezi ntlobo zimbini zegrafiti:
I. Igrafiti yeFlake
I-graphite ekristale enamaxolo namagqabi amancinci, kokukhona amaxolo amakhulu, kokukhona ixabiso lezoqoqosho liphezulu. Uninzi lwazo lusasazwa kwaye lusasazwa ematyeni. Lunendlela ecacileyo yokwalathisa. Ihambelana necala lenqanaba. Umxholo we-graphite ngokubanzi yi-3% ~ 10%, ukuya kuthi ga ngaphezulu kwe-20%. Idla ngokunxulunyaniswa neShi Ying, i-feldspar, i-diopside kunye nezinye iiminerali kumatye amandulo e-metamorphic (schist kunye ne-gneiss), kwaye inokubonwa nakwindawo yoqhagamshelwano phakathi kwelitye elitshisiweyo kunye nelitye lekalika. I-graphite eqatha inesakhiwo esineengqimba, kwaye ukuthambisa kwayo, ukuguquguquka kwayo, ukumelana nobushushu kunye nokuqhuba kombane kungcono kunezinye ii-graphite. Isetyenziswa kakhulu njengezinto zokwenza iimveliso ze-graphite ezicocekileyo kakhulu.
II. Igrafiti yomhlaba
I-graphite efana nomhlaba ikwabizwa ngokuba yi-graphite engaguqukiyo okanye i-cryptocrystalline graphite. Ububanzi bekristale bale graphite buhlala bungaphantsi kwe-1 micron, kwaye yi-aggregate ye-microcrystalline graphite, kwaye imo yekristale ingabonakala kuphela nge-electron microscope. Olu hlobo lwe-graphite lubonakaliswa ngumphezulu wayo womhlaba, ukungabikho kokukhanya, ukuthambisa okungekho semgangathweni kunye nomgangatho ophezulu. Ngokubanzi yi-60 ~ 80%, ezimbalwa ziphezulu ngaphezu kwe-90%, ukungahlambi kakuhle kwe-ore.
Ngokwabelana okungentla, siyazi ukuba kuyimfuneko ukwahlula iintlobo ezimbini zegrafiti kule nkqubo, ukuze izixhobo zikhethwe ngcono, nto leyo ebaluleke kakhulu kubavelisi bezicelo zegrafiti.
