Kugaragara kwa grafiti byadufashije cyane mu buzima bwacu. Uyu munsi, turareba ubwoko bwa grafiti, grafiti y'ubutaka na grafiti y'ibice. Nyuma y'ubushakashatsi bwinshi no gukoreshwa, ubwo bwoko bubiri bw'ibikoresho bya grafiti bufite agaciro gakomeye. Hano, umwanditsi mukuru wa grafiti ya Qingdao Furuite arakubwira itandukaniro riri hagati y'ubwo bwoko bubiri bwa grafiti:
I. Grafiti y'urukiramende
Grafite ikoze mu cyuma gifite ibipimo n'amababi yoroheje, uko ibipimo binini, niko agaciro k'ubukungu kazamuka. Inyinshi muri zo zikwirakwizwa kandi zigakwirakwizwa mu mabuye. Ifite imiterere igaragara y'icyerekezo. Ihuye n'icyerekezo cy'urwego. Ingano ya grafite muri rusange ni 3% ~ 10%, kugeza ku birenga 20%. Ikunze kujyana na Shi Ying, feldspar, diopside n'indi micungire y'amabuye ya kera (schist na gneiss), kandi ishobora no kugaragara mu gace k'aho amabuye yakoreshejwe n'amabuye ya limestone ahurira. Grafite ikoze mu cyuma ifite imiterere y'ibice, kandi ubushyuhe bwayo, ubwiyongere bwayo, ubushyuhe bwayo budashobora gutwarwa n'ubushyuhe n'amashanyarazi ni byiza kurusha iby'izindi grafite. Ikoreshwa cyane cyane nk'ibikoresho fatizo mu gukora ibikoresho bya grafite bifite isuku nyinshi.
II. Grafiti y'ubutaka
Graphite isa n'isi yitwa kandi graphite idahinduka cyangwa graphite ya cryptocrystalline. Ubunini bwa kristale y'iyi graphite muri rusange ni munsi ya mikoroni 1, kandi ni icyuma gihuriweho cya graphite ya microcrystalline, kandi imiterere ya kristale igaragara gusa hakoreshejwe mikorosikopi ya electron. Ubwo bwoko bwa graphite burangwa n'ubuso bwayo bw'ubutaka, kutagira urumuri, amavuta make n'ubuziranenge bwo hejuru. Muri rusange 60 ~ 80%, bike birenga 90%, ntibishobora kozwa neza mu mabuye y'agaciro.
Binyuze mu gusangira haruguru, tuzi ko ari ngombwa gutandukanya ubwoko bubiri bwa grafiti muri icyo gikorwa, kugira ngo ibikoresho bishobore gutoranywa neza, ibyo bikaba ari ingenzi cyane ku bakora porogaramu za grafiti.
