Ibiranga:
Irwanya cyane ubushyuhe: ifite igipimo gito cyane cy’ubushyuhe, ishobora kwihanganira impinduka zikomeye z’ubushyuhe mu gihe cyo kongera kuvugurura kandi ntiyoroshye gucikamo ibice.
Ikoranabuhanga rihendutse kandi rigezweho: 30% ~ 50% bihendutse ugereranije na SiC, ni igisubizo cy’umwimerere gikoreshwa mu gutwara abagenzi n’amakamyo yoroheje.
Imiterere ihuriweho: ifite umugozi ugororotse, umugongo uri hasi, kandi byoroshye kuyishyiraho.
Bikwiriye:
Imodoka za mazutu zo mu rugo SUV
Amakamyo yoroheje yo mu mujyi na bisi (aho imodoka zihagarara kenshi, imikorere yoroheje)
Ingengo y'imari nto, gushaka uburyo bwo gukoresha amafaranga neza
Ibiranga:
1. Kurwanya ubushyuhe bwinshi cyane:kugeza kuri 2700 ℃, ntabwoba gushya cyangwa gushonga.
2. Ubushyuhe bwihuta cyane:Ubushyuhe buvuguruye bukwirakwira ku buryo bungana, bufite ubushobozi bwo kongera kuvugurura kandi bugabanya ibyago byo guhumeka kw'ubushyuhe.
3.Imbaraga nyinshi, igihe kirekire cyo gukora:idashaje, irinda ingese, ishobora gukoreshwa imyaka 5-8 mu gihe cy'akazi gakomeye.
4. Umutwaro mwinshi wa karuboni:ishobora kubika umwotsi wa karuboni mwinshi, hamwe n'igihe kirekire cyo kongera kubyara, ikwiriye gukoreshwa mu gihe kirekire cyo kuremererwa cyane.
Bikwiriye:
Amakamyo manini, imashini z'ubwubatsi, ibinyabiziga bicukura amabuye y'agaciro (ibicuruzwa biremereye igihe kirekire, ubushyuhe bwinshi).
Imashini zitari iz'umuhanda, amamashini akoresha amashanyarazi.
Imikorere ikomeye hamwe no kongera kuvugurura kenshi no kuziba ivu byoroshye.
