1. Icyuma ni ikiifuro?
Ifuro ry'icyuma ni icyuma gisukuye gifite ububobere burenga 90% n'imbaraga runaka n'ubukomere. Iki gicuruzwa nigikoresho cyicyuma kirimo ifuro ya pore, ububobere burenze ubw'icyuma gisanzwe cyacumuye, kandi ubunini bwa pore burashobora kugera kuri mm 7.
Ifuro ry'icyuma ni ibyiciro bibiri bigize ibice bigizwe na pore yatatanye icyiciro na materique matrix skeleton ikomeza icyiciro nicyiciro, kandi imikorere yacyo biterwa ningaruka za matrice yicyuma, porosity, imiterere ya pore nuburyo bwo gutegura.

2. Ifuro ry'icyuma rishobora gukoreshwa mugutinda umuriro?
Ifuro ry'icyuma rifite amazi meza kandi irwanya umuriro. Irashobora gushirwa mu miyoboro itwara imyuka yaka umuriro cyangwa amazi kugirango ibuze umuriro gukwirakwizwa no gukurura ubushyuhe, bityo guhagarika iturika.
Iki gicuruzwa kibereye acetylene, ogisijeni ya flame yo gusudira hamwe n’ikoranabuhanga ryo guca gazi, moteri y’ubucukuzi n’amashanyarazi, gutunganya amavuta n’imiyoboro ya gaze ishobora gutwikwa, sisitemu yo gutwika, uburyo bwo kugarura peteroli na gaze, itanura rishyushya, sisitemu yo gutunganya gaze, n’ibindi. gukoreshwa kandi nkuzuza umuriro no kuzuza ibisasu byuzuza ibigega nka gaze ya lisansi na lisansi.
