Fibreglass ni iki?

Imigozi y'ibirahure ikoreshwa cyane bitewe nuko ihendutse kandi ifite imiterere myiza, cyane cyane mu nganda zikora ibintu bivanze. Mu kinyejana cya 18, Abanyaburayi bamenye ko ikirahure gishobora kuzungurutswamo imigozi yo kuboha. Isanduku y'Umwami w'Abafaransa Napoleon yari isanzwe ifite imyenda y'imitako ikoze muri fiberglass. Imigozi y'ibirahure ifite imigozi n'imigozi migufi cyangwa flocs. Imigozi y'ibirahure ikoreshwa cyane mu bikoresho bivanze, ibikoresho bya kabutike, imikandara yo kohereza ibicuruzwa, amatara, nibindi. Imigozi migufi ikoreshwa cyane cyane mu matike adaboshye, 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.

Fibre y'ikirahure polymeri zikomeye zigizwe n'ubwoko bunini bw'imigozi y'ibirahure itandukanye, nk'imigozi y'uburebure,insinga zaciwe, imikeka 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.

Imiterere y'ibirahure bya fibre

Ibintu by'ingenzi biranga fibre y'ikirahure birimo ibi bikurikira:

Kunyunyuza amazi ntibyoroshye:Fibre y'ikirahureNtibikwiriye imyenda irinda amazi kandi ntikwiriye gukoreshwa, kuko ibyuya bitazashira, bigatuma uwambaye yumva atose; kuko ibyo bikoresho bitagizweho ingaruka n'amazi, ntibizagabanuka.

Kudakomera: Kubera ko umwenda udafite ubushobozi bwo gukomera, nta buryo bwo kuwukuramo neza. Kubwibyo, ukeneye uburyo bwo kuwusukura kugira ngo udacika iminkanyari.

Ingufu nyinshi:Ikirahure cya Fiber Ikomeye cyane, hafi ya yose ingana na Kevlar. Ariko, iyo insinga zivanze, ziracika bigatuma umwenda usa n'uwacitse.

Gukingira: Mu buryo buhinnye, fiberglass ni icyuma gikingira neza.

Gupfuka: Indodo zipfuka neza, bigatuma ziba nziza ku madirishya.

Ubudahangarwa bw'ubushyuhe: Imigozi y'ikirahure ifite ubushyuhe bwinshi, ishobora kwihanganira ubushyuhe bugera kuri 315°C, ntigira ingaruka ku zuba, bleach, bagiteri, imyumbati, udukoko cyangwa alkali.

Bishobora kwangirika:Indodo z'ikirahure Biterwa n’aside hydrofluoric na aside fosforike ishyushye. Kubera ko fibre ari ikintu gikozwe mu kirahuri, hari fibre mbisi z’ibirahuri zigomba gufatwa neza, nk’ibikoresho byo mu rugo bikingira uruhu, kuko impera za fibre ziba zoroshye kandi zishobora gutobora uruhu, bityo uturindantoki tugomba kwambarwa mu gihe ukoresha fibre.

Gukoresha 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 Fiberglass Zifite 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.
