Fibre y'ibirahure ni iki?

Fibre yibirahure ifite ibyiza byinshi nkimbaraga nyinshi nuburemere bworoshye, kurwanya ruswa, kurwanya ubushyuhe bwinshi, gukora neza amashanyarazi, nibindi. Nibimwe mubikoresho bisanzwe bikoreshwa mubikoresho bikomatanya.Muri icyo gihe, Ubushinwa nabwo bukora cyane ku isi mu gukora fibre fibre.

1. Fibre ni ikiikirahure?

Fibre fibre ni organic organique idafite metallic ifite imikorere myiza, ni minerval naturel hamwe na silika nkibikoresho fatizo byingenzi, ongeramo ibikoresho bya minisiteri ya okiside yihariye, bivanze kimwe, bishongeshejwe mubushyuhe bwinshi, amazi yikirahure ashonga atembera mumazi asohoka, Uruhare rwihuta rukurura imbaraga rukuruzi rukururwa kandi rugakonja vuba kandi rukira muri fibre nziza ikomeza.

Ikirahuri cya fibre monofilament diameter kuva kuri microne nkeya kugeza kuri microne zirenga makumyabiri, bihwanye numusatsi wa 1 / 20-1 / 5, buri mugozi wa fibre ugizwe na monofilaments amagana cyangwa ibihumbi.

Ibirahuri bya fibre yibanze appearance Kugaragara hejuru yuburinganire bwa silindrike, igice cyambukiranya ni uruziga rwuzuye, ruzengurutse umurongo kugirango uhangane nubushobozi bwimizigo;gaze n'amazi binyuze mukurwanya ni bito, ariko hejuru biroroshye kuburyo imbaraga zifata fibre ari nto, ntabwo zifasha guhuza hamwe na resin;ubucucike muri rusange buri muri 2,50-2.70 g / cm3, bitewe ahanini nibirahuri;imbaraga zingana kurenza izindi fibre naturel, fibre synthique kugirango ibe ndende;ibikoresho byoroshye, kurambura kuruhuka ni bito cyane Kurwanya amazi no kurwanya aside nibyiza, mugihe kurwanya alkali ari bibi.

2.Ibyiciro bya fibre

Irashobora kugabanywamo fibre yibirahure ikomeza, fibre ngufi (fibre ndende yikirahure) hamwe nikirahure kirekire (LFT) uhereye kuburebure.

Uhereye ku byuma bya alkali birashobora kugabanywamo ibice bitarimo alkali, hasi, iringaniye kandi ndende, mubisanzwe byahinduwe hamwe na alkali idafite, ni ukuvuga E fibre yikirahure, guhindura murugo bikoreshwa muri E fibre.

3.Ni iki gishobora gukoresha fibre fibre

Fibre yibirahure ifite imbaraga zingana cyane, elastique nyinshi, kudakongoka, kurwanya imiti, kwinjiza amazi make, imikorere myiza yo gutunganya nibindi biranga ibintu byiza cyane, mubisanzwe nkibikoresho bikomatanya mubikoresho bishimangira, ibikoresho byokwirinda amashanyarazi nibikoresho byokwirinda, insimburangingo, nibindi. ., ikoreshwa cyane mubice bitandukanye.

Fibre y ibirahuri yo mumahanga igabanijwemo ibyiciro bine ukurikije imikoreshereze yibicuruzwa: ibikoresho bishimangira plastike ya thermosetting, ibikoresho byongera ibirahuri byongera ibikoresho bya thermoplastique, ibikoresho bya sima gypsumu, nibikoresho byimyenda y'ibirahure, muri byo ibikoresho bishimangira bingana na 70-75% hamwe nikirahure ibikoresho by'imyenda ya fibre bingana na 25-30%.Uhereye kubisabwa bikenerwa, ibikorwa remezo bingana na 38% (harimo umuyoboro, gusukurwa, gushyushya amazu no kwirinda amazi, kubungabunga amazi, nibindi), ubwikorezi bugera kuri 27-28% (yacht, ibinyabiziga, gari ya moshi yihuta, nibindi) na elegitoroniki bingana na 17%.

Guteranya, ahantu hashobora gukoreshwa fibre yibirahure ni ubwikorezi, ibikoresho byubwubatsi, inganda zamashanyarazi, inganda zubukanishi, inganda za peteroli, imyidagaduro numuco, hamwe nikoranabuhanga ryigihugu.
