Imiterere y'ibyuma bya grafiti

Imiterere y'ibyuma bya grafiti

1. Gukomera neza mu binyabutabire
Graphite ni ibikoresho bihoraho mu buryo busanzwe, kandi ubuziranenge bwayo mu buryo busanzwe ntiburuta ubw’amabuye y’agaciro. Ubushonge bwayo mu feza ishongeshejwe ni 0.001% - 0.002% gusa.GrafitiNtishobora gushonga mu bintu bidafite umwimerere cyangwa ibidafite umwimerere. Ntibishobora kwangirika cyangwa gushonga muri aside nyinshi, bases n'umunyu.
2. Ubudahangarwa bw'ubushyuhe bwinshi bw'ubwikorezi bwa grafiti
Binyuze mu igerageza, ubushyuhe bwa serivisi ya bearing grade general carbone bushobora kugera kuri 350 ℃; bearing graphite y'icyuma na yo ni 350 ℃; bearing graphite y'urwego rwa electrochemical ishobora kugera kuri 450-500 ℃ (mu gihe cyoroheje), imiterere yayo ifatika n'iy'ikoranabuhanga ntihinduka, kandi ubushyuhe bwayo bushobora kugera kuri 1000 ℃ mu gihe cy'umwuka udafite umwuka cyangwa ikirere kirinda.
3. Uburyo bwiza bwo kwisiga amavuta
Igipimo cya grafitiifite ubushobozi bwo kwisiga neza kubera impamvu ebyiri. Imwe mu mpamvu ni uko atome za karuboni ziri muri grafiti lattice zitondetse kuri buri ndege mu buryo busanzwe bwa hexagonal. Intera iri hagati ya atome iri hafi, ni ukuvuga 0.142 nm, mu gihe intera iri hagati ya planes ari 0.335 nm, kandi zihuzagurika mu cyerekezo kimwe. Inzira ya gatatu isubiramo aho planes ya mbere iherereye, iya kane isubiramo aho planes ya kabiri iherereye, n'ibindi. Muri buri ndege, imbaraga zo gufatanya hagati ya atome za karuboni ziba zikomeye cyane, mu gihe intera iri hagati ya planes ari nini, kandi imbaraga za van der Waals hagati yazo ziba nke cyane, bityo biroroshye kuva no kunyerera hagati y'ibice, ari nayo mpamvu nyamukuru ituma ibikoresho bya grafiti bigira ubushobozi bwo kwisiga.
Impamvu ya kabiri ni uko ibikoresho bya grafiti bifite icyuma gifatana cyane n'ibindi bikoresho byinshi by'icyuma, bityo grafiti yavuyemo ishobora gufatana byoroshye n'ubuso bw'icyuma iyo isya ikoresheje icyuma, igakora urwego rwafilime ya grafiti, biba ukugongana hagati ya grafiti na grafiti, bityo bigabanya cyane kwangirika no kwangirika kw'ibipimo, Iyi ni imwe mu mpamvu ituma ibyuma bya grafiti ya karuboni bigira ubushobozi bwo kwisiga no kurwanya gushyuha.
4. Indi miterere y'ubwiza bwa grafiti
Ugereranije n'izindi bearingers,amababa ya grafitikandi ifite ubushobozi bwo gutwara ubushyuhe bwinshi, ubushobozi buke bwo kwaguka mu buryo bugororotse, ubukonje bwihuse no kwirinda ubushyuhe n'ibindi.
