Manje emakethe, imikhondo eminingi yamapensela yenziwe nge-graphite yesikali, pho kungani i-graphite ikwazi ukwenza umkhondo wamapensela? Namuhla i-Furuite graphite xiaobian izokutshela ukuthi kungani i-graphite yesikali ingaba umthofu wepensela:
Kungani i-flake graphite ingasetshenziswa njengomthofu wepensela
Okokuqala nje, kumnyama; Okwesibili, inokwakheka okuthambile okushiya umkhondo njengoba ishelela kancane ephepheni. Uma uwubuka ngaphansi kwengilazi ekhulisayo, umbhalo wepensela wakhiwe ngezikali ezincane zegraphite.
Ama-athomu ekhabhoni ku-flake graphite ahlelwe abe yizingqimba, futhi ukuxhumana phakathi kwezingqimba kubuthakathaka kakhulu, kuyilapho ama-athomu ekhabhoni amathathu ezingqimbeni anamandla kakhulu, ngakho lapho ecindezelwa, izingqimba zishelela kalula, njengenqwaba yamakhadi okudlala. Ngokuphusha okuthambile, amakhadi ayahlukana.
Eqinisweni, umthofu wepensela wenziwe ngesikali segraphite nobumba oluxutshwe ngesilinganiso esithile. Ngokusho kwamazinga kazwelonke, kunezinhlobo ezingu-18 zamapensela ngokusho kokuhlushwa kwe-flake graphite. U-“H” umele ubumba futhi usetshenziselwa ukukhombisa ukuqina komthofu wepensela. Uma inombolo engaphambi kuka “H” iba nkulu, kuba nzima ukuhola, okusho ukuthi uma sikhulu isilinganiso sobumba obuxubene negraphite ekuholeni, amagama abonakala kancane, avame ukusetshenziselwa ukukopisha.
