Kukula kwa GFRP kumachokera ku kuchuluka kwa kufunikira kwa zida zatsopano zomwe zimagwira ntchito bwino kwambiri, zopepuka kulemera kwake, zosagwirizana ndi dzimbiri, komanso zogwiritsa ntchito mphamvu zambiri. Ndi chitukuko cha sayansi ya zinthu komanso kupititsa patsogolo luso lazopangapanga, GFRP pang'onopang'ono yapeza ntchito zosiyanasiyana m'magawo osiyanasiyana.GFRP nthawi zambiri imakhala ndigalasi la fiberglassndi resin matrix. Makamaka, GFRP ili ndi magawo atatu: fiberglass, resin matrix, ndi interface agent. Pakati pawo, fiberglass ndi gawo lofunikira la GFRP. Fiberglass amapangidwa ndi kusungunuka ndi kujambula galasi, ndipo chigawo chawo chachikulu ndi silicon dioxide (SiO2). Ulusi wagalasi uli ndi ubwino wokhala ndi mphamvu zambiri, kutsika kochepa, kutentha, ndi kukana kwa dzimbiri kuti apereke mphamvu ndi kuuma kwa zinthu. Chachiwiri, matrix a resin ndiye zomatira za GFRP. Matrices omwe amagwiritsidwa ntchito kawirikawiri amaphatikizapo polyester, epoxy, ndi phenolic resins. Resin matrix imakhala yomatira bwino, kukana kwamankhwala, komanso kukana kuwongolera kukonza ndi kuteteza magalasi a fiberglass ndi kusamutsa katundu. Komano, othandizira ophatikizana, amagwira ntchito yofunika kwambiri pakati pa fiberglass ndi resin matrix. Othandizira ophatikizika amatha kupititsa patsogolo kumamatira pakati pa fiberglass ndi resin matrix, ndikuwonjezera mawonekedwe amakina ndi kulimba kwa GFRP.
Kuphatikizika kwa mafakitale kwa GFRP kumafunikira izi:
(1) Kukonzekera kwa fiberglass:Zinthu zamagalasi zimatenthedwa ndikusungunuka, ndipo zimakonzedwa mosiyanasiyana ndi makulidwe a fiberglass ndi njira monga kujambula kapena kupopera mbewu mankhwalawa.
(2) Fiberglass Pretreatment:Thandizo lakuthupi kapena lamankhwala pamagalasi a fiberglass kuti awonjezere kuuma kwawo ndikuwongolera kumamatira kwapakati.
(3) Kukonzekera kwa fiberglass:Gawirani magalasi a fiberglass omwe adakonzedwa kale mu zida zomangira molingana ndi kapangidwe kake kuti apange mawonekedwe okonzedweratu a ulusi.
(4) Kupaka utomoni matrix:Valani utomoni mofanana pagalasi la fiberglass, ikani mitolo ya utomoni, ndikuyika ulusiwo kuti ugwirizane ndi matrix.
(5) Kuchiritsa:Kuchiritsa matrix a utomoni potenthetsa, kukakamiza, kapena kugwiritsa ntchito zida zothandizira (monga machiritso) kuti apange gulu lamphamvu.
(6) Pambuyo pa Chithandizo:GFRP yochiritsidwa imayang'aniridwa ndi njira zochizira pambuyo pa chithandizo monga kudula, kupukuta, ndi kupenta kuti akwaniritse mawonekedwe omaliza ndi mawonekedwe.
Kuchokera pamwambapa kukonzekera ndondomeko, zikhoza kuwoneka kuti mu ndondomeko yaKupanga kwa GFRP, Kukonzekera ndi kukonza magalasi a fiberglass kungasinthidwe molingana ndi zolinga zosiyanasiyana, matrices osiyanasiyana a utomoni wa ntchito zosiyanasiyana, ndi njira zosiyanasiyana zogwirira ntchito zingagwiritsidwe ntchito kukwaniritsa kupanga GFRP kwa ntchito zosiyanasiyana. Nthawi zambiri, GFRP nthawi zambiri imakhala ndi zinthu zingapo zabwino, zomwe zafotokozedwa mwatsatanetsatane pansipa:
(1) Wopepuka:GFRP ili ndi mphamvu yokoka yotsika poyerekeza ndi zida zachitsulo zachikhalidwe, motero ndiyopepuka. Izi zimapangitsa kuti zikhale zopindulitsa m'malo ambiri, monga mlengalenga, magalimoto, ndi zipangizo zamasewera, kumene kulemera kwa thupi kumatha kuchepetsedwa, zomwe zimapangitsa kuti ntchito ikhale yabwino komanso mafuta. Kugwiritsidwa ntchito pazomangamanga, mawonekedwe opepuka a GFRP amatha kuchepetsa kulemera kwa nyumba zazitali.
(2) Mphamvu Zapamwamba: Zida zowonjezera fiberglassali ndi mphamvu zambiri, makamaka mphamvu zawo zokhazikika komanso zosinthasintha. Kuphatikizika kwa fiber-reinforced resin matrix ndi fiberglass kumatha kupirira katundu wamkulu ndi kupsinjika, kotero kuti zinthuzo zimapambana pamakina.
(3) Kulimbana ndi dzimbiri:GFRP ili ndi kukana kwa dzimbiri kwabwino kwambiri ndipo sikukhudzidwa ndi zinthu zowononga monga asidi, alkali, ndi madzi amchere. Izi zimapangitsa zinthu zomwe zili m'malo ovuta kukhala opindulitsa kwambiri, monga gawo la uinjiniya wam'madzi, zida zama mankhwala, ndi akasinja osungira.
(4) Zabwino zoteteza:GFRP ili ndi zida zabwino zotsekera ndipo imatha kudzipatula bwino ma elekitirodi ndi matenthedwe amagetsi. Izi zimapangitsa kuti zinthuzo zizigwiritsidwa ntchito kwambiri pazaumisiri wamagetsi ndi kudzipatula kwamafuta, monga kupanga matabwa ozungulira, manja otsekereza, ndi zida zodzipatula zamafuta.
(5) Kukana kutentha kwabwino:GFRP ili ndikukana kutentha kwakukulundipo amatha kukhalabe okhazikika m'malo otentha kwambiri. Izi zimapangitsa kuti zizigwiritsidwa ntchito kwambiri muzamlengalenga, petrochemical, ndi minda yopangira magetsi, monga kupanga masamba a injini ya turbine, magawo ang'anjo, ndi zida zamagetsi zamagetsi zamagetsi.
Mwachidule, GFRP ili ndi maubwino amphamvu kwambiri, opepuka, kukana dzimbiri, zinthu zabwino zotetezera, komanso kukana kutentha. Zinthuzi zimapangitsa kuti zikhale zogwiritsidwa ntchito kwambiri pomanga, ndege, magalimoto, magetsi, ndi mafakitale a mankhwala.
