Manje emakethe, amapensela amaningi okuholela enziwe nge-flake graphite, pho kungani kungasetshenziswa i-flake graphite njenge-penselil lead? Namuhla, umhleli we-graphite ye-furuit uzokutshela ukuthi kungani i-flake graphite ingasetshenziswa njengomugqa wepensela:
Okokuqala, kumnyama; Okwesibili, unokuthungwa okuthambile okuslayida ephepheni futhi kushiya amamaki. Uma kubhekwa ngaphansi kwengilazi ekhulisayo, ukubhala ngesandla kwepensela kwakhiwa izinhlayiya ezinhle kakhulu ze-graphite graphite.
Ama-athomu e-carbon ngaphakathi kwe-graphite ye-flake ahlelwe ngezingqinamba, ukuxhumana phakathi kwezendlalelo kubuthakathaka kakhulu, futhi ama-athomu amathathu e-carbon ku-ungqimba axhumeke kakhulu, njengoba ungqimba kulula ukushelela ngemuva kokucindezelwa, njengesitaki samakhadi adlalayo, aslayida phakathi kwamakhadi.
Eqinisweni, ukuhola kwepensela kwakhiwa ngokuxuba i-graphite yesikali nobumba ngesilinganiso esithile. Ngokusho kweZinga Likazwelonke, kunezinhlobo eziyi-18 zamapensela ngokuya ngokuqoshwa kwe-flake graphite. I- "H" imele ubumba futhi isetshenziselwa ukukhombisa ubunzima bokuhola kwepensela. Lapho likhudlwana inani eliphambi kwe- "H", kunzima kakhulu ipensela lepensela, okungukuthi, ubukhulu bengxenye yobumba obuhlanganiswe negrafu eholwayo e-Pencil eholile, futhi kusobala ukuthi izinhlamvu zibhalwe, futhi zivame ukusetshenziselwa ukukopisha.
