1. Fibre y'ibirahure ni iki?
Fibre fibrezikoreshwa cyane bitewe nigiciro-cyiza hamwe nibintu byiza, cyane cyane mubikorwa byinganda. Nko mu kinyejana cya 18, Abanyaburayi bamenye ko ikirahure gishobora guhindurwamo fibre yo kuboha. Isanduku y'Umwami w'Abafaransa Napoleon yari isanzwe ifite imyenda yo gushushanya ikozwefiberglass. Ibirahuri by'ibirahure bifite filaments na fibre ngufi cyangwa flocs. Ibirahuri by'ibirahuri bikoreshwa mubikoresho byinshi, ibicuruzwa bya reberi, imikandara ya convoyeur, tarpauline, nibindi.
Ibirahuri bya fibre biranga umubiri nubukanishi, koroshya guhimba, nigiciro gito ugereranijefibrekora ibikoresho byo guhitamo imikorere-yimikorere myinshi. Ibirahuri by'ibirahure bigizwe na oxyde ya silika. Ibirahuri by'ibirahure bifite imiterere yubukanishi nko kutagabanuka, imbaraga nyinshi, gukomera no kuremerera.
Ibirahuri bya fibre byongerewe imbaraga bigizwe nicyiciro kinini cyubwoko butandukanye bwibirahure, nka fibre ndende, fibre yaciwe, matelo,uduce duto duto, kandi bikoreshwa mugutezimbere imashini na tribologiya ya polymer yibigize. Ibirahuri by'ibirahure birashobora kugera ku ntera ndende yo hejuru, ariko ubwitonzi bushobora gutera fibre kumeneka mugihe cyo kuyitunganya.
1.ibiranga fibre fibre
Ibintu nyamukuru biranga fibre yibirahure harimo ibintu bikurikira:
Ntibyoroshye gufata amazi:Fibre y ibirahuri irwanya amazi kandi ntabwo ibereye imyenda, kuko ibyuya ntibizakirwa, bigatuma uwambaye yumva atose; kubera ko ibikoresho bitatewe namazi, ntabwo bizagabanuka
Kudashyira mu gaciro:Bitewe no kubura elastique, umwenda ufite bike kurambura no gukira. Kubwibyo, bakeneye ubuvuzi bwo hejuru kugirango barwanye inkeke.
Imbaraga Zirenze:Fiberglass irakomeye cyane, hafi ikomeye nka Kevlar. Ariko, iyo fibre irikumwe, iravunika igatera umwenda gufata isura mbi.
Kwikingira:Muburyo bwa fibre fibre, fiberglass ninziza nziza.
Kunywa:Fibre iranyerera neza, bigatuma iba nziza kumyenda.
Kurwanya Ubushyuhe:Fibre yibirahure ifite ubushyuhe bwinshi, irashobora kwihanganira ubushyuhe bugera kuri 315 ° C, ntibibasirwa nizuba ryizuba, byakuya, bagiteri, ibumba, udukoko cyangwa alkalis.
Birashoboka:Fibre yibirahure yibasiwe na aside hydrofluoric na aside fosifori ishyushye. Kubera ko fibre ari igicuruzwa gishingiye ku kirahure, fibre zimwe z'ibirahure zigomba gukoreshwa neza, nk'ibikoresho byo mu rugo, kubera ko impera ya fibre yoroshye kandi ishobora gutobora uruhu, bityo uturindantoki tugomba kwambara mugihe dukora fibre.
3. Gukora inzira ya fibre yibirahure
Fibreni fibre idafite ibyuma ikoreshwa cyane nkibikoresho byinganda. Mubisanzwe, ibikoresho fatizo bya fibre yibirahure birimo imyunyu ngugu itandukanye hamwe n’imiti yakozwe n'abantu, ibyingenzi ni umucanga wa silika, hekeste na ivu rya soda.
Umusenyi wa Silica ukora nk'ikirahure cyahoze, mugihe ivu rya soda na hekeste bifasha kugabanya ubushyuhe bwo gushonga. Coefficente yo kwaguka yubushyuhe hamwe nubushyuhe buke ugereranije na asibesitosi na fibre organic ituma fiberglass yibikoresho bihamye bigabanya ubushyuhe vuba.
Fibre fibrebikozwe no gushonga mu buryo butaziguye, bikubiyemo inzira nko guhuza, gushonga, kuzunguruka, gutwikira, gukama, no gupakira. Icyiciro nuburyo bwambere bwo gukora ibirahure, aho ibintu byinshi bivangwa neza hanyuma imvange ikoherezwa mu ziko kugirango bishonge ku bushyuhe bwinshi bwa 1400 ° C. Ubu bushyuhe burahagije kugirango uhindure umucanga nibindi bikoresho muburyo bwashongeshejwe; ikirahure gishongeshejwe noneho gitemba munganda kandi ubushyuhe buragabanuka kugera kuri 1370 ° C.
Mugihe cyo kuzunguruka fibre yibirahure, ikirahure gishongeshejwe gisohoka mumaboko afite umwobo mwiza cyane. Isahani ya liner yashyutswe hakoreshejwe ikoranabuhanga kandi ubushyuhe bwayo bugenzurwa kugirango habeho ubwiza buhoraho. Indege y'amazi yakoreshejwe mu gukonjesha filime kuko yasohotse mu ntoki ku bushyuhe bwa dogere 1204 ° C.
Umugezi usohotse wikirahure gishongeshejwe ushushanya muburyo bwa fayili hamwe na diametero kuva kuri 4 mm kugeza 34 mkm. Impagarara zitangwa hifashishijwe umuyaga mwinshi kandi ikirahure cyashongeshejwe gikururwa. Mu cyiciro cyanyuma, imiti yimiti yamavuta, binders hamwe ningingo zifatika zikoreshwa kuri filaments. Gusiga amavuta bifasha kurinda filaments gukuramo kuko byegeranijwe kandi bikomeretsa mubipaki. Nyuma yo gupima, fibre zumishwa mu ziko; filaments noneho iriteguye kugirango irusheho gutunganyirizwa muri fibre yaciwe, kuzunguruka cyangwa ubudodo.
4.ikoreshwa rya fibre fibre
Fiberglass ni ibintu bidasanzwe bidatwika kandi bigumana hafi 25% byimbaraga zayo za mbere kuri 540 ° C. Imiti myinshi ntigira ingaruka nke kuri fibre yibirahure. Fiberglass idafite ingufu ntishobora kubumba cyangwa kwangirika. Fibre fibre yibasiwe na acide hydrofluoric, aside fosifori ishyushye nibintu bikomeye bya alkaline.
Nibikoresho byiza byamashanyarazi.Imyenda ya fibrebifite imiterere nko kwinjiza amazi make, imbaraga nyinshi, kurwanya ubushyuhe hamwe na dielectric idahoraho, bigatuma iba imbaraga nziza kubibaho byacapwe byacapwe hamwe na langi.
Ikigereranyo kinini-cy-uburemere bwa fiberglass ituma iba ibikoresho byiza kubisabwa bisaba imbaraga nyinshi nuburemere buke. Muburyo bwimyenda, izo mbaraga zirashobora kuba icyerekezo kimwe cyangwa ibyerekezo byombi, bigatuma habaho guhinduka mugushushanya no kugiciro cyibisabwa byinshi mumasoko yimodoka, ubwubatsi bwa gisivili, ibicuruzwa bya siporo, ikirere, inyanja, ibikoresho bya elegitoronike, Ingufu n’umuyaga.
Zikoreshwa kandi mugukora ibihimbano byubatswe, imbaho zumuzingo zacapwe hamwe nibicuruzwa bidasanzwe-bigamije. Umusaruro w’ibirahure bya buri mwaka ku isi ni toni zigera kuri miliyoni 4.5, naho abayikora cyane ni Ubushinwa (umugabane w’isoko 60%), Amerika n’umuryango w’ubumwe bw’ibihugu by’Uburayi.
