1. Fibre y'ikirahure ni iki?
Indodo z'ikirahurezikoreshwa cyane bitewe nuko zihendutse kandi zifite imiterere myiza, cyane cyane mu nganda zikora ibintu bivanze. Mu kinyejana cya 18, Abanyaburayi bamenye ko ikirahure cyashoboraga kuzungurutswamo imigozi yo kuboha. Isanduku y'Umwami w'Abafaransa Napoleon yari isanzwe ifite imyenda y'imitako ikoze murifiberglass. Imigozi y'ikirahure ifite imigozi n'imigozi migufi cyangwa flocs. Imigozi y'ikirahure ikunze gukoreshwa mu bikoresho bivanze, ibikoresho bya kabutike, imikandara yo kohereza ibicuruzwa, amatara, n'ibindi. Imigozi migufi ikoreshwa cyane cyane mu bikoresho bidaboshye, pulasitiki y'ubuhanga n'ibikoresho bivanze.
Imiterere myiza y'ibirahure n'iy'imashini, byoroshye gukora, kandi bihendutse ugereranije nafibre ya karubonibigira ibikoresho byiza cyane mu gukoresha mu buryo bugezweho. Imigozi y'ikirahure igizwe na okiside ya silica. Imigozi y'ikirahure ifite imiterere myiza cyane nko kuba idakomeye cyane, ikomeye cyane, idakomeye cyane kandi ifite uburemere bworoshye.
Polima zikomejwe n'imigozi y'ikirahure zigizwe n'ubwoko bunini bw'imigozi y'ikirahure itandukanye, nk'imigozi miremire, imigozi yaciwe, imigozi iboshye, naimitako yaciwe, kandi bikoreshwa mu kunoza imiterere ya polymer composites. Fibres z'ikirahure zishobora kugera ku gipimo cyo hejuru cy'imiterere y'ibice, ariko fragile ishobora gutuma fibres zicika mu gihe cyo kuzitunganya.
1. Ibiranga fibre y'ikirahure
Ibintu by'ingenzi biranga fibre y'ikirahure birimo ibi bikurikira:
Kunyunyuza amazi ntibyoroshye:Fibre y'ikirahure irinda amazi kandi ntikwiriye imyenda, kuko ibyuya bitazashira, bigatuma uyambaye yumva atose; kuko ibyo bikoresho bitagizweho ingaruka n'amazi, ntibizagabanuka
Kutagira ubwisanzure:Kubera ko umwenda udafite ubushobozi bwo gukaraba neza, ntugira ubushobozi bwo kuvura no kuvura neza. Kubwibyo, ukeneye uburyo bwo kuwusukura kugira ngo udacika iminkanyari.
Ingufu nyinshi:Fiberglass irakomeye cyane, hafi ya yose ingana na Kevlar. Ariko iyo insinga zihuye, ziracika bigatuma umwenda usa n'uwacitse.
Ubwishingizi bw'umuriro:Mu buryo buhinnye, fiberglass ni igikoresho cyiza cyane cyo gukingira.
Guhindagurika:Indodo zipfuka neza, bigatuma ziba nziza cyane ku madirishya.
Ubudahangarwa bw'ubushyuhe:Insinga z'ikirahure zirwanya ubushyuhe bwinshi, zishobora kwihanganira ubushyuhe bugera kuri 315°C, ntizibasirwa n'izuba, bleach, bagiteri, mold, dukoko cyangwa alkali.
Bishobora kwangirika:Imigozi y'ikirahure iterwa n'aside hydrofluoric na aside fosforique ishyushye. Kubera ko iyo fibre ari ikintu gikozwe mu kirahure, hari imigozi y'ikirahure ikwiye gufatwa neza, nk'ibikoresho byo mu rugo bikingira, kuko impera z'imigozi ziba zoroshye kandi zishobora gutobora uruhu, bityo uturindantoki tugomba kwambarwa mu gihe ukoresha fiberglass.
3. Uburyo bwo gukora fibre y'ibirahure
Fibre y'ikirahureni fibre idakoresha icyuma ikoreshwa cyane muri iki gihe nk'ibikoresho by'inganda. Muri rusange, ibikoresho by'ibanze bya fibre y'ibirahure birimo imyunyu ngugu itandukanye n'ibinyabutabire byakozwe n'abantu, ibice by'ingenzi ni umusenyi wa silica, limestone na soda ash.
Umucanga wa silica ukora nk'ikirahure, mu gihe ivu rya soda n'amabuye y'agaciro bifasha kugabanya ubushyuhe bushongesha. Kuba ubushyuhe buke bukwirakwira hamwe n'ubushyuhe buke ugereranije na asbestos na fibre organic bituma fiberglass iba ibikoresho bihamye kandi bigabanya ubushyuhe vuba.
Indodo z'ikirahureBikorwa no gushonga mu buryo butaziguye, bikubiyemo inzira nko gushonga, gushonga, kuzunguruka, gusiga, kumisha no gupakira. Itsinda ni ryo shingiro ry’ikorwa ry’ibirahure, aho ingano y’ibikoresho ivangwa neza hanyuma imvange ikoherezwa mu itanura kugira ngo ishonge ku bushyuhe bwinshi bwa 1400°C. Ubu bushyuhe burahagije kugira ngo umucanga n’ibindi bikoresho bihinduke mu buryo bushongeshejwe; ikirahure gishongeshejwe gihita cyinjira mu cyuma gitunganya ibintu hanyuma ubushyuhe bukagabanuka bukagera kuri 1370°C.
Mu gihe cyo kuzunguruka imigozi y'ibirahure, ikirahure gishongeshejwe gisohoka mu gipfunyika gifite utwenge duto cyane. Igipfunyika gishyushya hakoreshejwe ikoranabuhanga kandi ubushyuhe bwacyo bugenzurwa kugira ngo gikomeze kuba gihamye. Umuyoboro w'amazi wakoreshejwe mu gukonjesha umugozi ubwo wasohokaga mu gipfunyika ku bushyuhe bwa dogere selisiyusi zigera kuri 1204.
Umugezi w'ibirahure bishongeshejwe uvamo ukoresheje ikoranabuhanga mu migozi ifite umurambararo kuva kuri 4 μm kugeza kuri 34 μm. Hatangwa imbaraga hakoreshejwe icyuma gishyushya cyane hanyuma ikirahure gishongeshejwe kigashyirwamo imigozi. Mu cyiciro cya nyuma, hashyirwamo amavuta, imigozi n'ibikoresho bihuza imigozi. Gusiga amavuta bifasha kurinda imigozi gushwanyagurika uko ikusanyirizwa hamwe igashyirwa mu mapaki. Nyuma yo gupima, imigozi yumishwa mu ifuru; imigozi iba yiteguye gukomeza gutunganywamo imigozi, imigozi cyangwa ubudodo.
4.ikoreshwa rya fibre y'ikirahure
Ikirahure cya Fiber ni ibintu bidafite umwimerere bidashya kandi bigumana hafi 25% by'imbaraga zabyo za mbere kuri 540°C. Ibinyabutabire byinshi bigira ingaruka nke ku migozi y'ibirahure. Fibreglass idafite umwimerere ntizahinduka cyangwa ngo yononekare. Imigozi y'ibirahure igirwaho ingaruka na aside hydrofluoric, aside phosphoric ishyushye n'ibintu bikomeye bya alkaline.
Ni ibikoresho by'amashanyarazi byiza cyane bikingira ubushyuhe.Imyenda ya FiberglassZifite imiterere nk'ubushuhe buke, imbaraga nyinshi, ubushobozi bwo kwirinda ubushyuhe n'ubushobozi buke bwo gukoresha dielectric, bigatuma ziba ibikoresho byiza byo gushimangira imikorere y'imbaho zacapwe na varnish zirinda ubushyuhe.
Igipimo cy’imbaraga nyinshi hagati y’uburemere bwa fiberglass gituma iba ibikoresho byiza cyane byo gukoreshwa bisaba imbaraga nyinshi n’uburemere buke. Mu buryo bw’imyenda, iyi mbaraga ishobora kuba imwe cyangwa ibiri, bigatuma habaho ubwisanzure mu miterere n’ikiguzi ku bikorwa bitandukanye ku isoko ry’imodoka, ubwubatsi bw’ibyatsi, ibikoresho bya siporo, iby’indege, iby’amazi, iby’ibikoresho by’ikoranabuhanga, iby’urugo n’iby’umuyaga.
Zikoreshwa kandi mu gukora ibintu bivanze mu nyubako, imiyoboro yacapwe n'ibindi bikoresho bitandukanye byihariye. Umusaruro w'ibirahuri ku isi buri mwaka ni toni miliyoni 4.5, kandi abakora cyane ni Ubushinwa (60% by'isoko), Leta Zunze Ubumwe za Amerika n'Umuryango w'Ubumwe bw'u Burayi.
