Fibre y'ikirahure ifite ibyiza byinshi nko gukomera no koroshya, kurwanya ingese, kurwanya ubushyuhe bwinshi, imikorere myiza yo gukingira amashanyarazi, nibindi. Ni kimwe mu bikoresho fatizo bikunze gukoreshwa mu gukora ibikoresho bivanze. Muri icyo gihe, Ubushinwa ni nabwo bukora fibre y'ikirahure ku isi.
1. Fibre ni ikiikirahure?
Fibre y'ikirahure ni ibikoresho bidafite imiterere y'ubutare kandi bifite imikorere myiza cyane, ni amabuye y'agaciro karemano afite silica nk'ibikoresho by'ingenzi, yongeraho ibikoresho byihariye by'amabuye y'agaciro ya okiside y'icyuma, bivanze neza, bishongeshejwe ku bushyuhe bwinshi, amazi y'ikirahure ashongeshejwe anyura mu muyoboro w'amazi, uruhare rw'imbaraga rukuruzi zikurura vuba rurakururwa kandi rugakonjeshwa vuba rukavamo fibre nziza cyane ikomeza.
Umurambararo wa fibre y'ikirahure ni kuva kuri mikoroni nke kugeza kuri mikoroni zirenga makumyabiri, bingana n'umusatsi wa 1/20-1/5, buri gapfunyika k'imigozi kagizwe n'imigozi amagana cyangwa ibihumbi.
Imiterere y'ibanze ya fibre y'ikirahure: Ishusho y'ubuso bworoshye bw'umuzenguruko, igice cy'umuzenguruko ni uruziga rwuzuye, igice cy'umuzenguruko kizunguruka kugira ngo gishobore kwihanganira ubushobozi bwo gutwara; gaze n'amazi binyura mu burwanyi ni bike, ariko ubuso ni bworoshye ku buryo imbaraga zo gufata fibre ari nto, zidahuza na resin; ubucucike muri rusange buri kuri 2.50-2.70 g/cm3, bitewe ahanini n'imiterere y'ikirahure; imbaraga zo gukurura kurusha izindi fibre karemano, fibre zikozwe mu buryo bwa sintetike ziba nyinshi; ibikoresho byoroshye, uburebure bw'aho bicika ni buto cyane. Ubudahangarwa bw'amazi n'ubudahangarwa bw'aside ni byiza, mu gihe ubudahangarwa bw'aside ari bubi.
2.Ishyirwa mu byiciro rya fibre y'ikirahure
Ishobora kugabanywamo fibre y'ikirahure ihoraho, fibre y'ikirahure ngufi (fixed length glass fiber) na fibre y'ikirahure kirekire (LFT) uhereye ku cyiciro cy'uburebure.
Uhereye ku cyuma kirimo alkali, gishobora kugabanywamo ibice bibiri: bidafite alkali, bike, biciriritse n'ibinini, akenshi bihindurwamo fibre y'ikirahure idafite alkali, ni ukuvuga fibre y'ikirahure ya E, guhindura mu rugo muri rusange bikoreshwa fibre y'ikirahure ya E.
3.Ni iki imiyoboro y'ikirahure ishobora gukoreshwa
Fibre y'ikirahure ifite imbaraga nyinshi zo gukurura, ubushyuhe bwinshi, idashya, idakoresha imiti, amazi make, imikorere myiza yo kuyitunganya n'ibindi byiza, akenshi nk'ibikoresho bivanze mu bikoresho bikomeza imbaraga, ibikoresho by'amashanyarazi bikingira n'ibikoresho bikingira, substrate y'uruziga, nibindi, bikoreshwa cyane mu nzego zitandukanye.
Fibre y'ibirahure byo mu mahanga igabanyijemo ibice bine hakurikijwe ikoreshwa ry'ibicuruzwa: ibikoresho byo kongera imbaraga mu gushyiramo thermosetting, ibikoresho byo kongera imbaraga mu byuma bikoresha thermoplastics, ibikoresho byo kongera imbaraga mu byuma bikoresha sima, n'ibikoresho byo kongera imbaraga mu byuma bikoresha gypsum, muri byo ibikoresho byo kongera imbaraga bigira 70-75% naho ibikoresho byo kongera imbaraga mu byuma bikoresha glass fibre bigira 25-30%. Ukurikije ibikenewe, ibikorwa remezo bigira 38% (harimo imiyoboro, gukuramo umunyu, gushyushya no kurinda amazi, kubungabunga amazi, nibindi), ubwikorezi bugera kuri 27-28% (ubwato, imodoka, gari ya moshi yihuta, nibindi) naho ibikoresho by'ikoranabuhanga bigira 17%.
Muri make, ahantu hakoreshwa fibre z'ibirahure ni nko gutwara abantu n'ibintu, ibikoresho by'ubwubatsi, inganda z'amashanyarazi, inganda z'imashini, inganda zikora peteroli, imyidagaduro n'umuco, hamwe n'ikoranabuhanga ryo kurinda igihugu.
