Tsopano pamsika, mapensulo ambiri amapangidwa ndi sikelo ya graphite, ndiye chifukwa chiyani ma graphite amatha kupanga ma pensulo otsogolera? Lero Furuite graphite xiaobian ikuuzani chifukwa chake sikelo ya graphite ingakhale chowongolera cha pensulo:
Chifukwa chiyani flake graphite angagwiritsidwe ntchito ngati pensulo lead
Choyamba, ndi chakuda; Chachiwiri, imakhala ndi mawonekedwe ofewa omwe amasiya kachidutswa kakang'ono kamene kamayenda pang'onopang'ono pamapepala. Mukachiyang'ana pansi pa galasi lokulitsa, cholembera cha pensulocho chimakhala ndi masikelo ang'onoang'ono a graphite.
Ma atomu a carbon omwe ali mu flake graphite amakonzedwa m’magulu, ndipo kugwirizana pakati pa zigawozo n’kofooka kwambiri, pamene maatomu atatu a carbon omwe ali m’zigawozo ndi amphamvu kwambiri, choncho akakanikizidwa, zigawozo zimatsetsereka mosavuta, ngati mulu wa makadi akusewera. Ndi kukankha modekha, makhadiwo amaphwasuka.
M'malo mwake, chotsogola cha pensulo chimapangidwa ndi sikelo ya graphite ndi dongo losakanikirana ndi gawo linalake. Malinga ndi miyezo ya dziko, pali mitundu 18 ya mapensulo malinga ndi kuchuluka kwa flake graphite. "H" amaimira dongo ndipo amagwiritsidwa ntchito kusonyeza kuuma kwa pensulo. Chiwerengero chachikulu chisanafike "H", chiwongolero cholimba, kutanthauza kuti gawo lalikulu la dongo losakanizidwa ndi graphite kutsogolo, mawu osawoneka bwino, omwe amagwiritsidwa ntchito nthawi zambiri kukopera.
