Fibre y'ikirahure ifite imiterere myiza kandi ikoreshwa cyane mu nzego nyinshi. Ni ibikoresho bidakoresha ibyuma bidashobora gusimbura icyuma. Kubera ko bifite amahirwe meza yo gutera imbere, amasosiyete akomeye akora fibre y'ikirahure ari kwibanda ku bushakashatsi ku mikorere myiza no kunoza imikorere y'ibirahure.

Umwobo w'ibirahuri bya Fiberglass

1 Ibisobanuro bya fibre y'ikirahure
Fibre y'ikirahure ni ubwoko bw'ibikoresho bidakoresha ibyuma bidafite imiterere y'umwimerere bishobora gusimbura icyuma kandi bifite imikorere myiza cyane. Bitegurwa hakoreshejwe gukuramo ikirahure gishongeshejwe mu migozi binyuze mu bikorwa by'ingufu zo hanze. Bifite imiterere y'imbaraga nyinshi, modulus nyinshi no kugabanuka k'uburebure. Kurwanya ubushyuhe no gukanda, coefficient nini yo kwagura ubushyuhe, aho gushonga cyane, ubushyuhe bwayo bworoshye bushobora kugera kuri 550 ~ 750 ℃, kudahinduka neza mu binyabutabire, ntabwo byoroshye gutwika, bifite imiterere myiza nko kudahangana n'ingufu, kandi byakoreshejwe cyane mu nzego nyinshi.
 
2 Ibiranga fibre y'ikirahure
Ingano y'ingufu z'ibirahure ni 680°C, ingano y'ingufu z'ibirahure ni 1000°C, naho ubucucike ni 2.4～2.7g/cm3. Ingufu zo gukurura ni 6.3 kugeza 6.9 g/d mu buryo busanzwe na 5.4 kugeza 5.8 g/d mu buryo butose.Fibre y'ikirahure ifite ubushobozi bwo kwihanganira ubushyuhe kandi ni ibikoresho byo mu rwego rwo hejuru bikingira ubushyuhe bifite ubushobozi bwo kwirinda ubushyuhe, bikaba bikwiriye mu gukora ibikoresho bikingira ubushyuhe n'ibidashya.
 
3 Imiterere ya fibre y'ikirahure
Ikirahure gikoreshwa mu gukora imigozi y'ibirahure gitandukanye n'ikirahure gikoreshwa mu bindi bicuruzwa by'ibirahure. Ikirahure gikoreshwa mu gukora imigozi y'ibirahure kirimo ibi bikurikira:
(1)Ikirahure cy'amashanyarazi,izwi kandi nka ikirahuri kidafite alkali, ni icya borosilicate glass. Mu bikoresho bikoreshwa ubu mu gukora insinga z'ibirahuri, ikirahuri kidafite alkali ni cyo gikoreshwa cyane. Ikirahuri kidafite alkali gifite ubushobozi bwo gukingira no gutunganya neza insinga z'ibirahuri, kandi gikoreshwa cyane cyane mu gukora insinga z'ibirahuri zirinda ubushyuhe n'insinga z'ibirahuri zikomeye, ariko ikirahuri kidafite alkali ntikirwanya ingese ya aside inorganic, bityo ntikibereye gukoreshwa ahantu hafite aside. Dufite ikirahuri cya e-glassurujya n'uruza rw'ibirahuri bya fiberglassikirahuri cy'ikoranabuhangaurujya n'uruza rw'ibirahuri biboshye，n'ikirahure cya elegitoronikiumutako wa fibegrlass.
 
(2)Ikirahure cya C, izwi kandi nka ikirahure kiri hagati ya alkali. Ugereranyije n'ikirahure kidafite alkali, gifite ubushobozi bwo kurwanya imiti kandi gifite imiterere mibi y'amashanyarazi n'imashini. Kongera diboron trichloride mu kirahure kiri hagati ya alkali bishobora gutangaumutako wo hejuru w'ibirahure bya fibre,ifite imiterere yo kudakira ingese. Imigozi y'ibirahuri idafite boroni ikoreshwa cyane cyane mu gukora imyenda iyungurura n'imyenda ipfunyika.

Umupira w'ikirahure waciwemo imigozi

(3)Fibre y'ikirahure ikomeye cyane,nkuko izina ribigaragaza, fibre y'ikirahure ikomeye cyane ifite imiterere y'imbaraga nyinshi n'uburyo bwinshi bwo gukora. Ingufu zayo zo gukora fibre ni 2800MPa, iri hejuru ya 25% ugereranyije n'iya fibre y'ikirahure idafite alkali, naho modulus yayo yoroshye ni 86000MPa, iri hejuru ugereranyije n'iya fibre y'ikirahure ya E. Umusaruro wa fibre y'ikirahure ikomeye ntabwo uri hejuru, hamwe n'imbaraga zayo nyinshi n'uburyo bwinshi bwo gukora, bityo muri rusange ikoreshwa mu bya gisirikare, mu kirere no mu bikoresho bya siporo n'ahandi, kandi ntikoreshwa cyane mu bindi bice.
 
(4)Fibre y'ikirahure ya AR, izwi kandi nka fibre y'ikirahure irwanya alkali, ni fibre idakomoka ku bimera. Fibre y'ikirahure irwanya alkali ifite ubudahangarwa bwiza kandi ishobora kurwanya kwangirika kw'ibintu bifite alkali nyinshi. Ifite modulus yoroshye cyane kandi irwanya ingaruka, imbaraga zo gukurura no gukomera. Ifite kandi imiterere yo kudashya, kurwanya ubukonje, kurwanya ubushyuhe n'ubushuhe, kurwanya imyakura, kudapfa, plasticity ikomeye no gushushanya byoroshye. Ibikoresho byo mu mbaho ​​bya fibre y'ikirahure bikonjeshwa na sima.
 
4 Gutegura insinga z'ikirahure
Uburyo bwo gukorafibre y'ikirahureMuri rusange ni ukubanza gushongesha ibikoresho fatizo, hanyuma bigakorwa mu gutunganya fibre. Niba bigomba gukorwa mu ishusho y'udupira tw'ibirahure cyangwa uduti twa fiberglass, gutunganya fibre ntibishobora gukorwa mu buryo butaziguye. Hariho inzira eshatu zo gutunganya fibre ku migozi y'ibirahure:
Uburyo bwo gushushanya: uburyo bw'ingenzi ni uburyo bwo gushushanya umunwa w'udupira, hagakurikiraho uburyo bwo gushushanya inkoni y'ikirahure n'uburyo bwo gushushanya amadomo ashongeshejwe;
Uburyo bwo gupima uburebure bw'imashini: gupima ingoma, gupima intambwe no gupima disiki ya porcelain itambitse;
Uburyo bwo gupfumura: uburyo bwo gupfumura n'uburyo bwo gupfumura imiyoboro.
Izi nzira nyinshi zavuzwe haruguru zishobora no gukoreshwa hamwe, nko gukurura no gukurura n'ibindi. Nyuma yo gutunganya bibaho nyuma yo gutunganya fibre. Nyuma yo gutunganya fibre z'ikirahure cy'imyenda bigabanyijemo intambwe ebyiri z'ingenzi zikurikira:
(1) Mu gihe cyo gukora imigozi y'ibirahuri, imigozi y'ibirahuri ihujwe mbere yo kuyizunguza igomba kuba ifite ingano, kandi imigozi migufi igomba gusukwaho amavuta mbere yo kuyikusanya no kuyiteramo imyobo.
(2) Gukomeza gutunganya, hakurikijwe uko fibre y'ikirahure kimeze n'iy'ikirahure kigufigutemberera mu byuma by'ikirahure hari intambwe zikurikira:
①Intambwe ngufi zo gutunganya fibre y'ibirahure:
