Ikoranabuhanga ryimodoka ryatejwe imbere, ibikoresho byibikoresho byo guterana nabyo byahinduwe muburyo bwose, bigabanijwemo ibyiciro byinshi byingenzi:
Icyuma cya feri kama
Mbere ya za 1970, feri yerekana feri yarimo ibikoresho byinshi bya asibesitosi, ifata ubushyuhe bwinshi, kurwanya umuriro, hamwe nibiranga ubushyamirane, ariko kubera ko ifu yakozwe na asibesitosi mugukora no kuyikoresha, hari ibyangiritse bitandukanye kumubiri wumuntu. , bikaba byoroshye gutera sisitemu y'ubuhumekero.Indwara ni kanseri, bityo feri y'ipamba irabujijwe kwisi yose.
Noneho, feri ya feri kama isanzwe yitwa feri ya NAO (Non-Asbestos Organic, nta feri ya feri idafite amabuye), ubusanzwe irimo 10% -30% yibikoresho byicyuma, kandi ikubiyemo fibre yibimera, Fibre yibirahure, karubone, reberi, ikirahure nibindi bikoresho.
Amashanyarazi ya feri kama yazamuye imikorere mukwambara no kugenzura urusaku mumyaka myinshi yiterambere no kunoza ibintu, ariko kandi birakwiriye gutwara buri munsi.Umukungugu wabyaye kandi ibyangiritse kuri disiki ya feri ni bike.Nyamara, bitewe nigiciro cyibikoresho, nibindi, firime ya feri kama muri rusange ihenze, kandi uruganda rwumwimerere ruzakoreshwa muburyo bugezweho kandi bwohejuru.
Icyuma cya feri yicyuma
Icyitwa kimwe cya kabiri cyicyuma kiri mubikoresho byo guteranya bikoreshwa mumashanyarazi, kuva kuri 30% -65% yicyuma - harimo umuringa, icyuma, nibindi. Ibiranga iyi feri ni byiza cyane, birwanya ubushyuhe bwinshi, ugereranije igiciro gito, kandi ibibi biterwa nimpamvu zifatika, urusaku mugihe cya feri ruzaba runini, kandi kwambara ibikoresho byuma kuri disiki ya feri bizaba binini.Kubera ko icyuma cya feri yicyuma gifite ibiranga natwe hejuru, hano haribintu bibiri byingenzi, kimwe ni uruganda rwumwimerere rushyigikira feri yicyuma giciriritse kandi cyo hasi - iyi kamere nigiciro gito.Ikindi cyerekezo kiri mubice byuruhu rwa feri yahinduwe - kubera ko feri yicyuma ari nziza, irakwiriye cyane kumodoka ikora cyane cyangwa mubikorwa bitandukanye.Nyuma ya byose, muri ubu buryo bwo gukoresha, ubushyuhe ntarengwa bwuruhu rwa feri buzagera no kuri dogere zirenga 800.Turashobora rero kubona ko ibirango byinshi byahinduwe bifite ibikoresho byicyuma byo hejuru kuri feri yo gutwara bikabije nibyabaye.
Ceramic feri
Feri ya ceramic feri irashobora gusobanurwa nkibidahagije kumashanyarazi ya feri kama nicyuma.Ibikoresho byayo bihujwe cyane cyane nibikoresho bitandukanye nka fibre minerval, fibre aramide, na ceramic fibre.Ku ruhande rumwe, mugihe nta bikoresho byicyuma, feri ya feri na disiki ya feri, urusaku ruzagabanuka cyane.Muri icyo gihe, ibyangiritse kuri disiki ya feri bizagabanuka cyane.Byongeye kandi, feri yububiko bwa ceramic irashobora kuguma ihagaze neza mubushyuhe bwinshi, ikirinda feri ya feri kama cyangwa ibyuma kubera feri ndende cyangwa yihuta cyane, kubera imbaraga za feri yibintu byashonga, byongera umutekano muke.Nubundi kwambara.
