Ibirahuri by'ibirahure birashobora kugabanywamo fibre ikomeza, fibre ndende ihamye hamwe nubwoya bw'ikirahure ukurikije imiterere n'uburebure.Ukurikije ibice byikirahure, birashobora kugabanywamo ibice bitarimo alkali, birwanya imiti, alkali ndende, alkali yo hagati, imbaraga nyinshi, modulus nini ya elastike hamwe na fibre yibirahure (alkali-irwanya).
Ibikoresho by'ibanze byo gukora fibre y'ibirahure ni umucanga wa quartz, alumina na pyrophyllite, hekeste, dolomite, aside boric, ivu rya soda, mirabilite na fluorite.Uburyo bwo kubyaza umusaruro bushobora kugabanywamo ibice bibiri: kimwe ni ugukora ibirahuri bishongeshejwe muri fibre;Imwe muriyo nuko ikirahure gishongeshejwe gikozwe mumipira yikirahure cyangwa inkoni zifite umurambararo wa 20mm, hanyuma ugashyuha kandi ugashongeshwa muburyo butandukanye bwo gukora fibre nziza cyane ifite diameter ya 3 ~ 80 μ m.Uburebure butagira umupaka bukozwe muburyo bwo gushushanya bwa kare hakoreshejwe plaque ya platine bita fibre fibre ikomeza, ikunze kwitwa fibre ndende.Fibre idahwitse ikozwe na roller cyangwa ikirere byitwa fibre ndende-ibirahure, bikunze kwitwa fibre ngufi.
Fibre fibre igabanijwemo amanota atandukanye ukurikije ibiyigize, imiterere n'imikoreshereze.Ukurikije icyiciro gisanzwe (reba imbonerahamwe), E-fibre y'ibirahuri ni byo bikoreshwa cyane kandi bikoreshwa cyane mubikoresho byo gukwirakwiza amashanyarazi.Icyiciro s ni fibre idasanzwe.
Ikirahuri gikoreshwa mu gusya fibre y'ibirahure kugirango ikore fibre y'ibirahure itandukanye nibindi bicuruzwa.Ibirahuri bya fibre byacurujwe mumahanga ni ibi bikurikira:
Ikirahure
Azwi kandi nk'ikirahuri kitarimo alkali, ni ikirahuri cya borosilike.Kugeza ubu, ni fibre ikoreshwa cyane mubirahure, ifite amashanyarazi meza hamwe nubukanishi.Ikoreshwa cyane mugukora fibre yibirahuri kugirango ikoreshwe amashanyarazi na fibre yikirahure ya fibre fibre plastike ikomezwa.Ikibi cyayo nuko byoroshye kwangirika na acide organique, bityo ntibikwiye kubidukikije.
C- ikirahure
Inkoni ya fibre fibre, izwi kandi nk'ikirahuri giciriritse-alkali, irangwa no kurwanya imiti neza, cyane cyane irwanya aside, kuruta ikirahure kitarimo alkali, ariko imikorere yacyo y'amashanyarazi ni mibi, kandi imbaraga za mashini ziri munsi ya 10% ~ 20% ugereranije n'iya alkali idafite ibirahuri fibre.Ubusanzwe, ibirahuri byo mu mahanga bya alkali byo mu bwoko bwa alkali birimo urugero runaka rwa boron trioxide, mu gihe Ubushinwa bwo hagati bw’ibirahuri bya alkali bitarimo boron na gato.Mu bihugu by'amahanga, fibre yo hagati ya alkali ikoreshwa gusa mu gukora ibicuruzwa biva mu kirahure birwanya ruswa, nk'ibirahure by'ibirahure byunvikana, kandi bikoreshwa no gushimangira ibikoresho byo gusakara asfalt.Nyamara, mu Bushinwa, fibre yo mu bwoko bwa alkali iringaniye irenga kimwe cya kabiri (60%) y’umusemburo w’ibirahure, kandi ikoreshwa cyane mu gushimangira fibre y’ibirahure ikomezwa no gukora imyenda yo kuyungurura no gupfunyika, kuko igiciro cyayo ari munsi ugereranije na fibre fibre idafite alkali kandi ifite ubushobozi bwo guhangana.
imbaraga nyinshi z'ikirahure
Irangwa n'imbaraga nyinshi na modulus yo hejuru.Imbaraga imwe ya fibre tensile ni 2800MPa, ikaba iri hejuru ya 25% ugereranije niy'ibirahuri bitagira alkali, naho modulike yayo ya elastique ni 86000MPa, ikaba isumba iy'ibikoresho bya E- ikirahure.Ibicuruzwa bya FRP byakorewe hamwe nabyo bikoreshwa cyane mubikorwa bya gisirikare, umwanya, ibirwanisho bitagira amasasu nibikoresho bya siporo.Nyamara, kubera igiciro kiri hejuru, ntishobora kwamamara mugukoresha abaturage ubu, kandi umusaruro wisi ni toni ibihumbi byinshi.
AR fibre fibre
Azwi kandi nka fibre idashobora kwihanganira fibre, fibre idashobora kwihanganira ibirahuri nibikoresho byimbavu bya fibre yibirahure bishimangirwa (sima) beto (GRC kubugufi), ikaba fibre 100% idasanzwe kandi isimbuza icyuma na asibesitosi mubitari umutwaro -kutwara ibice bya sima.Fibre idashobora kwihanganira ibirahuri irangwa no kurwanya alkali nziza, kurwanya neza kwangirika kwibintu byinshi bya alkali muri sima, gufata cyane, modulus ya elastike cyane, kurwanya ingaruka, imbaraga zikaze nimbaraga zunama, imbaraga zidashobora gukomera, kurwanya ubukonje, ubushyuhe na Ubushuhe bwo guhangana nubushuhe, kwihanganira gukomeye no kudahinduka, gushushanya gukomeye no kubumba byoroshye.Alkali idashobora kwihanganira ibirahuri ni ubwoko bushya bukoreshwa cyane muri beto ikora neza (sima).
Ikirahure
Bizwi kandi nk'ikirahure kinini cya alkali, ni ikirahuri gisanzwe cya sodium silikatike, idakunze gukoreshwa mu gukora fibre y'ibirahure kubera kutarwanya amazi.
E-CR ikirahure
Nibirahure bitarimo boron na alkali idafite ikirahure, ikoreshwa mugukora fibre yikirahure irwanya aside nziza kandi irwanya amazi.Kurwanya amazi kwayo gukubye inshuro 7-8 kurenza iy'ibirahuri bitagira alkali, kandi irwanya aside iruta cyane iy'ibirahuri bya alkali yo hagati.Nubwoko bushya bwatunganijwe byumwihariko kumiyoboro yo munsi y'ubutaka n'ibigega byo kubikamo.
D ikirahure
Bizwi kandi nk'ikirahure gito cya dielectric, ikoreshwa mugukora fibre nkeya ya dielectric fibre ifite imbaraga nziza za dielectric.
Usibye ibice byavuzwe haruguru byavuzwe haruguru, hashyizweho fibre nshya idafite ibirahuri idafite alkali, idafite boron na gato, bityo bikagabanya umwanda w’ibidukikije, ariko amashanyarazi y’amashanyarazi hamwe n’ibikoresho bya mashini bisa n’ibya E-ikirahuri gakondo.Byongeye kandi, hari ubwoko bwa fibre fibre ifite ibirahuri bibiri, byakoreshejwe mugukora ubwoya bwikirahure, kandi bivugwa ko bifite ubushobozi nkibishimangira FRP.Byongeye kandi, hari fibre idafite ibirahuri idafite florine, ikaba ari fibre nziza ya alkali idafite ibirahuri byakozwe kugirango bikingire ibidukikije.
Kumenya fibre ndende ya alkali
Uburyo bworoshye bwo kugenzura ni uguteka fibre mumazi abira mumasaha 6-7.Niba ari fibre yumunyu mwinshi wa alkali glauber, nyuma yamazi abira, fibre mumutwe hamwe nicyerekezo cyo kuboha izaba
Ibipimo byose birarekuye.
Ukurikije ibipimo bitandukanye, hariho inzira nyinshi zo gutondekanya fibre yibirahure, mubisanzwe uhereye kuburebure na diameter, ibihimbano nibikorwa.
