Ukuthuthukiswa kwe-GFRP kuvela ekwandeni kwesidingo sezinto ezintsha ezisebenza kahle kakhulu, ezinesisindo esilula, ezimelana nokugqwala, futhi ezisebenzisa amandla kahle. Ngokuthuthuka kwesayensi yezinto ezibonakalayo kanye nokuthuthukiswa okuqhubekayo kobuchwepheshe bokukhiqiza, i-GFRP iye yazuza kancane kancane izinhlobo eziningi zezicelo emikhakheni eyahlukahlukene. I-GFRP ngokuvamile iqukethei-fiberglasskanye ne-resin matrix. Ngokukhethekile, i-GFRP yakhiwa izingxenye ezintathu: i-fiberglass, i-resin matrix, kanye ne-interfacial agent. Phakathi kwazo, i-fiberglass iyingxenye ebalulekile ye-GFRP. I-Fiberglass yenziwa ngokuncibilikisa nokudonsa ingilazi, futhi ingxenye yayo eyinhloko yi-silicon dioxide (SiO2). Imicu yengilazi inezinzuzo zamandla aphezulu, ukuminyana okuphansi, ukushisa, kanye nokumelana nokugqwala ukuze inikeze amandla nokuqina kwezinto. Okwesibili, i-resin matrix iyisinamathiseli se-GFRP. Ama-resin matrices asetshenziswa kakhulu afaka phakathi i-polyester, i-epoxy, kanye ne-phenolic resins. I-resin matrix inokunamathela okuhle, ukumelana namakhemikhali, kanye nokumelana nomthelela wokulungisa nokuvikela i-fiberglass kanye nemithwalo yokudlulisa. Ngakolunye uhlangothi, ama-interfacial agents adlala indima ebalulekile phakathi kwe-fiberglass kanye ne-resin matrix. Ama-interfacial agents angathuthukisa ukunamathela phakathi kwe-fiberglass kanye ne-resin matrix, futhi athuthukise izakhiwo zemishini kanye nokuqina kwe-GFRP.
Ukuhlanganiswa okuvamile kwezimboni kwe-GFRP kudinga izinyathelo ezilandelayo:
(1) Ukulungiswa kwe-fiberglass:Izinto zengilazi ziyashiswa futhi zincibilikiswe, bese zilungiswa zibe yizimo nobukhulu obuhlukene be-fiberglass ngezindlela ezifana nokudweba noma ukufafaza.
(2) Ukwelashwa Kwangaphambi Kwe-Fiberglass:Ukwelashwa kobuso be-fiberglass ngokomzimba noma ngamakhemikhali ukuze kwandiswe ukujiya kobuso babo futhi kuthuthukiswe ukunamathelana kwe-interfacial.
(3) Ukuhlelwa kwe-fiberglass:Sabalalisa i-fiberglass elungisiwe kusengaphambili emshinini wokubumba ngokwezidingo zomklamo ukuze wakhe isakhiwo sokuhlelwa kwe-fiber esinqunyiwe.
(4) I-matrix ye-resin yokumboza:Gcoba i-resin matrix ngokulinganayo ku-fiberglass, ugcwalise ama-fiber bundles, bese ubeka ama-fiber ukuthintana ngokugcwele ne-resin matrix.
(5) Ukwelapha:Ukwelapha i-resin matrix ngokushisa, ukucindezela, noma ukusebenzisa izinto ezisizayo (isb. i-ejenti yokwelapha) ukwakha isakhiwo esiqinile esihlanganisiwe.
(6) Ngemva kokwelashwa:I-GFRP ephulukisiwe ifakwa ezinqubweni zangemva kokwelashwa njengokusika, ukupholisha, nokupenda ukuze kufezwe ikhwalithi yokugcina yobuso kanye nezidingo zokubukeka.
Kusukela enkambisweni yokulungiselela engenhla, kungabonakala ukuthi enkambisweniUkukhiqizwa kwe-GFRP, ukulungiswa kanye nokuhlelwa kwe-fiberglass kungalungiswa ngokwezinjongo zenqubo ezahlukene, ama-resin matrices ahlukene ezinhlelo zokusebenza ezahlukene, kanye nezindlela ezahlukene zokucubungula ngemuva kokufeza ukukhiqizwa kwe-GFRP kwezinhlelo zokusebenza ezahlukene. Ngokuvamile, i-GFRP ivame ukuba nezinhlobo ezahlukene zezakhiwo ezinhle, ezichazwe ngokuningiliziwe ngezansi:
(1) Ilula:I-GFRP inomzwelo ophansi uma iqhathaniswa nezinto zensimbi zendabuko, ngakho-ke ilula kakhulu. Lokhu kuyenza ibe nenzuzo ezindaweni eziningi, njengezindiza, izimoto, kanye nemishini yezemidlalo, lapho isisindo esifile sesakhiwo singancishiswa khona, okuholela ekusebenzeni okuthuthukisiwe kanye nokusebenza kahle kukaphethiloli. Isetshenziswa ezakhiweni zokwakha, isimo esilula se-GFRP singanciphisa ngempumelelo isisindo sezakhiwo eziphakeme.
(2) Amandla Aphezulu: Izinto eziqiniswe nge-fiberglasszinamandla aphezulu, ikakhulukazi amandla azo okuthamba nokuguquguquka. Inhlanganisela ye-fiber-reinforced resin matrix kanye ne-fiberglass ingamelana nemithwalo emikhulu kanye nokucindezeleka, ngakho-ke le nto idlula zonke izici zemishini.
(3) Ukumelana nokugqwala:I-GFRP inokumelana okuhle kakhulu nokugqwala futhi ayithinteki ezindabeni ezigqwalisayo njenge-asidi, i-alkali, namanzi anosawoti. Lokhu kwenza izinto ezisendaweni ehlukahlukene enobunzima zibe yinzuzo enkulu, njengasemkhakheni wobunjiniyela basolwandle, imishini yamakhemikhali, kanye namathangi okugcina izinto.
(4) Izakhiwo ezinhle zokuvikela:I-GFRP inezakhiwo ezinhle zokuvimbela ukushisa futhi ingahlukanisa ngempumelelo ukuqhutshwa kwamandla kagesi kanye nokushisa. Lokhu kwenza izinto ezisetshenziswa kabanzi emkhakheni wobunjiniyela kagesi kanye nokususwa kokushisa, njengokwenziwa kwamabhodi wesekethe, imikhono yokuvimbela ukushisa, kanye nezinto zokuhlukanisa ukushisa.
(5) Ukumelana okuhle nokushisa:I-GFRP inayoukumelana nokushisa okuphezulufuthi iyakwazi ukugcina ukusebenza okuzinzile ezindaweni ezishisa kakhulu. Lokhu kuyenza isetshenziswe kabanzi emkhakheni wezindiza, we-petrochemical, kanye nowokukhiqiza ugesi, njengokukhiqiza ama-blade enjini ye-turbine yegesi, izingxenye zesithando somlilo, kanye nezingxenye zemishini yesitshalo samandla okushisa.
Ngamafuphi, i-GFRP inezinzuzo zamandla aphezulu, ulula, ukumelana nokugqwala, izakhiwo ezinhle zokuvimbela ukushisa, kanye nokumelana nokushisa. Lezi zakhiwo zenza kube yinto esetshenziswa kabanzi embonini yokwakha, yezindiza, yezimoto, yamandla kanye neyekhemikhali.
