1. Ubukene bw'ibyuma byiza cyane buri kwiyongera
Iki ni kimwe mu bintu by'ingenzi bituma isoko rya electrode za grafiti rikura. Iterambere ryihuse ry’inganda z’ibyuma nk’ubwubatsi, imodoka, ibikorwa remezo, iby’indege n’ubwirinzi bw’igihugu byatumye ubwiyongere bw’ibikenewe n’umusaruro w’ibyuma.
2. Ifuru y'amashanyarazi ni yo igezweho muri iki gihe
Bitewe n’uburinzi bw’ibidukikije n’uburyo bworoshye bwo gukora, inzira yo gukora ibyuma mu bihugu bikiri mu nzira y’amajyambere irahinduka kuva ku itanura riturika n’itanura rinini rijya ku itanura rikoresha amashanyarazi (EAF). Ama-electrode ya grafiti ni yo soko nyamukuru y’ingufu zikoreshwa mu icupa ry’amashanyarazi, kandi kugeza kuri 70% by’ama-electrode ya grafiti akoreshwa mu icupa ry’amashanyarazi rikoresha amashanyarazi. Iterambere ryihuse ry’itanura rikoresha amashanyarazi rituma ubushobozi bwo gukora electrode ya grafiti bwiyongera.
3. Electrode za Graphite ni ibikoresho bishobora gukoreshwa
Igihe cyo gukoresha electrode ya grafiti muri rusange ni ibyumweru bibiri. Ariko, ukwezi gukora electrode ya grafiti muri rusange ni amezi 4-5. Muri iki gihe cyo gukoresha, ubushobozi bwo gukora electrode ya grafiti buteganijwe kugabanuka bitewe na politiki y'igihugu n'igihe cy'ubushyuhe.
4. Indwara ya Needle Coke yo mu rwego rwo hejuru nta kiguzi ihari
Ifu ya Needle coke ni igikoresho cy'ingenzi mu gukora electrode za grafiti. Ni coke ya peteroli ya calcium (CPC) ingana na 70% by'ikiguzi cy'inyongera mu gukora electrode za grafiti. Izamuka ry'ibiciro riterwa n'umubare muto w'imashini zitumizwa mu mahanga za needle coke ni yo mpamvu nyamukuru y'izamuka ry'ibiciro bya electrode za grafiti. Hagati aho, ifu ya needle coke ikoreshwa kandi mu gukora ibikoresho bya electrode ku bateri za lithium n'inganda zikora iby'indege. Izi mpinduka mu gutanga no gukenera bituma igiciro cya electrode ya grafiti kidahinduka.
5. Intambara z'Ubucuruzi hagati y'Ubukungu Bukuru bw'Isi
Ibi byatumye icyuma cyoherezwa mu mahanga cy’Ubushinwa kigabanuka cyane, bituma ibindi bihugu byongera ubushobozi bwo gukora. Ku rundi ruhande, byanatumye ingano y’amashanyarazi ya grafiti yoherezwa mu mahanga mu Bushinwa yiyongera. Byongeye kandi, Leta Zunze Ubumwe za Amerika zongereye imisoro ku bicuruzwa by’Ubushinwa bitumizwa mu mahanga, ibyo bikaba byaragabanyije cyane inyungu ku biciro bya electrodes za grafiti zo mu Bushinwa.
