Ubwoya bw'ikirahuri ni ubwoko bwa fibre artificiel.Ikoresha umucanga wa quartz, hekeste, dolomite nandi mabuye karemano nkibikoresho byingenzi, bifatanije n ivu rya soda, borax nibindi bikoresho bya chimique kugirango bishonga mubirahure.Mugihe cyashonge, kijugunywa mumibabi myiza ya flokculent hakoreshejwe imbaraga zo hanze no guhuha.Fibre na fibre byambukiranya-bitatu kandi byuzuzanya, byerekana icyuho kinini.Ibyuho bishobora gufatwa nkibibyimba.Kubwibyo, ubwoya bwikirahure bushobora gufatwa nkibintu byoroshye bifite ubushyuhe bwiza bwumuriro hamwe nuburyo bwo kwinjiza amajwi.

Ubwoya bw'ikirahuri bwa centrifugal bwiyumvamo kandi bufite uburyo bwiza cyane bwo kwinjiza no gukurura amajwi, cyane cyane bugira ingaruka nziza zo kwifata ku muvuduko muke ndetse no mu majwi atandukanye yo kunyeganyega, bifasha kugabanya umwanda w’urusaku no guteza imbere aho ukorera.
Ubwoya bw'ikirahuri bwunvikana na aluminium foil veneer nabwo bufite imbaraga zo kurwanya imishwarara.Nibikoresho byiza byogukoresha amajwi yubushyuhe bwo hejuru, ibyumba byo kugenzura, ibyumba byimashini, ibice hamwe nigisenge kibase.
Ubwoya bw'ikirahure butagira umuriro (bushobora gutwikirwa na aluminiyumu, n'ibindi) bifite ibyiza byinshi nka retardant flame, idafite uburozi, irwanya ruswa, ubwinshi bwumuriro, ubushyuhe buke bw’umuriro, imbaraga zikomeye z’imiti, kwinjiza amazi make, kwangiza amazi, n'ibindi. .

Ibirimo bike mubirahuri byubwoya bwa slag ball hamwe na fibre yoroheje birashobora kugumya umwuka no kubuza gutemba.Ikuraho ihererekanyabubasha rya convection ihumanya ikirere, igabanya cyane ubushyuhe bwumuriro wibicuruzwa, kandi igahita yihutisha ihererekanyabubasha ryamajwi, bityo ikagira ubushyuhe bwiza bwumuriro, kwinjiza amajwi ningaruka zo kugabanya urusaku.

Ubwoya bw'ikirahure bufite ubushyuhe bwiza bwo hejuru, ubushyuhe burambye no kurwanya ubushyuhe bwo kugabanuka.Irashobora kubungabunga umutekano, ituze hamwe nubushobozi buhanitse mugihe kirekire mugihe cyateganijwe cyo gukora ubushyuhe hamwe nibikorwa bisanzwe.

Amazi ashingiye kumazi bivuga ubushobozi bwibikoresho byo kurwanya amazi.Ubwoya bw'ikirahure bwacu bugera ku gipimo cyo kurwanya amazi kitari munsi ya 98%, bigatuma kigira imikorere ikomeza kandi ihamye.

Ntabwo irimo asibesitosi, nta shusho, nta shingiro ry’imikurire ya mikorobe, kandi izwi nkigicuruzwa cyangiza ibidukikije n’ikigo cy’igihugu gishinzwe gupima ibikoresho byubaka.
