Ipulasitiki Eqinisiwe Ye-Fiberglass (i-FRP/i-GFRP)
* Imikhiqizo ye-fiberglass eyenziwe ngokwezifiso, epakishwe futhi ithunyelwe ngokwezidingo zokwenza ngokwezifiso!
* I-FRP, eyaziwa nangokuthi i-Fiber Reinforced Plastic (FRP), iyinto ehlanganisiwe eyakhiwe ngemicu yengilazi kanye ne-resin. Inezakhiwo ezinhle kakhulu zemishini kanye nokumelana nokugqwala, futhi isetshenziswa kabanzi emikhunjini, ezimotweni, ekwakheni, embonini yamakhemikhali, emandleni kagesi nakwezinye izinkambu.
* Imikhiqizo noma izingxenye zepulasitiki ze-FRP ezenziwe ngezifiso
I-FRP uhlobo lwezinto ezihlanganisiwe, ezenziwe nge-fiber yengilazi kanye nemikhiqizo yayo efana nendwangu yengilazi, i-tape, i-felt kanye ne-yarn njengezinto zokuqinisa kanye ne-resin yokwenziwa njengezinto ze-matrix. Ngenxa yamandla ayo ilingana nensimbi, futhi iqukethe izingxenye zengilazi, futhi inombala, ukuma, ukumelana nokugqwala, ukufudumala kukagesi, ukufudumala kokushisa kanye nezinye izakhiwo zengilazi, ngakho-ke ibizwa ngokomfanekiso ngokuthi "ipulasitiki eqinisiwe ye-fiber yengilazi".
I-FRP yaziwa ngesilinganiso sayo samandla aphezulu nesisindo, ukumelana nokugqwala, kanye nokuqina futhi isetshenziswa ezinhlobonhlobo zezicelo ezifana nezimboni zezimoto, zezindiza, zokwakha, kanye nezasolwandle kanye nasensimini yezinto zokuhlobisa.
Yiziphi izinzuzo ezinikezwa yi-FRP kunezinye ipulasitiki?
Ukwengeza imicu kuma-fiber engilazi kunciphisa isisindo futhi kwandisa i-modulus yokuguquguquka kanye namandla omshini. Ngenxa yalokho, lezi zinto zingasetshenziswa ukukhiqiza izingxenye ezidinga ukwakheka okunembile, imikhawulo yokubekezelelana esethiwe, ukukhathala okuphansi, ukumelana nomthelela omkhulu kanye nezakhiwo ezinhle zokucindezela. Zingenza kube lula ukwakheka kwezingxenye futhi zithuthukise ukukhiqizwa kanye nokusebenza kahle. Ama-FRP nawo anezakhiwo ezinhle kakhulu zokushisa kanye nokushisa kwe-acoustic futhi angamelana nokuhlaselwa ngamakhemikhali aqothulayo, umthelela wamagagasi, izindawo ezinomswakama kanye neziphepho/iziphepho.

Inqubo yokukhiqiza i-Fiberglass
Ngokwezici zezinto ze-FRP, izinqubo zokukhiqiza ezisetshenziswa kakhulu zifaka phakathi ukubumba okugoqekayo, ukubumba kokuqondanisa, ukubumba kokucindezela, kanye nokubumba ngesandla.
Yiziphi izakhiwo i-FRP enazo?
* Okokuqala, isisindo esincane kanye namandla aphezulu: ukuminyana kwe-FRP kuphakathi kuka-1.5~2.0, yi-1/4~1/5 kuphela yensimbi yekhabhoni, kodwa amandla okudonseka asondele noma adlula lawo ensimbi yekhabhoni. Amandla athile okudonseka e-epoxy FRP, amandla okudlala kanye nokucindezela angafinyelela ngaphezu kuka-400Mpa.
* Okwesibili, izakhiwo zikagesi ezinhle: I-FRP iyinto enhle kakhulu yokuvikela ugesi, esetshenziselwa ukwenza ama-insulator, imvamisa ephezulu isengavikela izakhiwo ezinhle ze-dielectric.

Okwesithathu, ukusebenza kahle kokushisa: Ukushisa okuphansi kwe-FRP, insimbi engu-1/100 ~ 1/1000 kuphela, kuyinto enhle kakhulu yokuvikela ukushisa.
Okwesine, ukuklanywa okuhle: ngokwesidingo sokuklama imikhiqizo eyahlukahlukene yesakhiwo ukuze kuhlangatshezwane nezidingo zokusetshenziswa komkhiqizo kungenziwa kube nobuqotho obuhle. Kungakhetha futhi ngokugcwele izinto ukuze kuhlangatshezwane nokusebenza komkhiqizo.
Okwesihlanu, umsebenzi omuhle kakhulu: ngokuya ngesimo somkhiqizo, izidingo zobuchwepheshe, ukusetshenziswa kanye nenani lokukhetha okuguquguqukayo kwenqubo yokubumba. Inqubo ilula, ingabunjwa ngesikhathi esisodwa, umphumela wezomnotho uvelele, ikakhulukazi ngesimo sezinto eziyinkimbinkimbi, akulula ukwakha inani elincane lemikhiqizo, elivelele kakhulu ekuphakameni kwalo kwenqubo.
