Ukuthuthukiswa kwe-GFRP kusukela ekukhuleni kwesidingo sezinto ezintsha ezisebenza kahle kakhulu, isisindo esilula, ukumelana nokugqwala, namandla awonga kakhulu. Ngokuthuthuka kwesayensi yezinto ezibonakalayo kanye nokwenza ngcono okuqhubekayo kobuchwepheshe bokukhiqiza, i-GFRP kancane kancane iye yazuza inhlobonhlobo yezinhlelo zokusebenza emikhakheni eyahlukene. I-GFRP ngokuvamile iqukethei-fiberglasskanye ne-resin matrix. Ngokukhethekile, i-GFRP iqukethe izingxenye ezintathu: i-fiberglass, i-resin matrix, ne-ejenti yokuhlangana ubuso. Phakathi kwabo, i-fiberglass iyingxenye ebalulekile ye-GFRP. I-fiberglass yenziwe ngokuncibilika nokudweba ingilazi, futhi ingxenye yabo eyinhloko i-silicon dioxide (SiO2). Imicu yengilazi inezinzuzo zamandla aphezulu, ukuminyana okuphansi, ukushisa, nokumelana nokugqwala ukunikeza amandla nokuqina kwento. Okwesibili, i-resin matrix iyingcina ye-GFRP. Ama-matrices e-resin asetshenziswa kakhulu afaka i-polyester, i-epoxy, ne-phenolic resins. I-resin matrix inokunamathela okuhle, ukumelana namakhemikhali, kanye nokumelana nomthelela ukulungisa nokuvikela i-fiberglass nokudlulisa imithwalo. Ngakolunye uhlangothi, ama-interfacial agents adlala indima ebalulekile phakathi kwe-fiberglass ne-resin matrix. Ama-ejenti ahlanganayo angathuthukisa ukunamathela phakathi kwe-fiberglass ne-resin matrix, futhi athuthukise izakhiwo zemishini nokuqina kwe-GFRP.
Ukwakhiwa kwezimboni okujwayelekile kwe-GFRP kudinga izinyathelo ezilandelayo:
(1) Ukulungiswa kwe-Fiberglass:Izinto zengilazi ziyashiswa futhi ziyancibilika, futhi zilungiswa zibe yizimo nobukhulu obuhlukahlukene be-fiberglass ngezindlela ezinjengokudweba noma ukufutha.
(2) I-Fiberglass Pretreatment:Ukwelashwa kwendawo ebonakalayo noma yamakhemikhali ye-fiberglass ukuze kwandiswe ubuqhwaga obungaphezulu nokuthuthukisa ukunamathela kobuso.
(3) Ukuhlelwa kwe-fiberglass:Sabalalisa ingilazi ye-fiberglass eselashwe ngaphambilini ezinsizeni zokubumba ngokuya ngezidingo zedizayini ukuze wenze ukwakheka okunqunywe kusengaphambili kwefayibha.
(4) I-coating resin matrix:Gcoba i-resin matrix ngendlela efanayo ku-fiberglass, faka izinyanda zefiber, futhi ubeke imicu ixhumene ngokugcwele ne-resin matrix.
(5) Ukwelapha:Ukwelapha i-resin matrix ngokufudumeza, ngokucindezela, noma ngokusebenzisa izinto ezisizayo (isb. i-ejenti yokwelapha) ukwakha isakhiwo esiqinile esiyinhlanganisela.
(6) Ngemuva kokwelashwa:I-GFRP eselashiwe ingaphansi kwezinqubo zangemuva kokwelashwa ezifana nokusikwa, ukupholishwa, nokudweba ukuze kuzuzwe ikhwalithi yokugcina yendawo kanye nezidingo zokubukeka.
Kusukela kunqubo yokulungiselela engenhla, kungabonakala ukuthi ohlelweni lweUkukhiqizwa kwe-GFRP, ukulungiswa kanye nokuhlelwa kwe-fiberglass kungalungiswa ngokuvumelana nezinjongo zenqubo ehlukene, ama-matrices e-resin ahlukene wezinhlelo zokusebenza ezahlukene, nezindlela ezahlukene zokucubungula ngemva kokucubungula zingasetshenziswa ukufeza ukukhiqizwa kwe-GFRP yezinhlelo zokusebenza ezahlukene. Ngokuvamile, i-GFRP ivame ukuba nezinhlobonhlobo zezakhiwo ezinhle, ezichazwe ngokuningiliziwe ngezansi:
(1) Isisindo esincane:I-GFRP ine-gravity ethize ephansi uma iqhathaniswa nezinto zensimbi zendabuko, ngakho-ke ayisindi uma kuqhathaniswa. Lokhu kwenza kube nenzuzo ezindaweni eziningi, njenge-aerospace, izimoto, kanye nemishini yezemidlalo, lapho isisindo esifile sesakhiwo singancishiswa, okuholela ekusebenzeni okuthuthukisiwe nokusebenza kahle kukaphethiloli. Kusetshenziswa ezakhiweni zokwakha, imvelo engasindi ye-GFRP inganciphisa ngempumelelo isisindo sezakhiwo eziphakeme kakhulu.
(2) Amandla Aphezulu: Izinto eziqiniswe nge-Fiberglassbabe namandla aphezulu, ikakhulukazi amandla abo okudonsa kanye nokuguquguquka. Inhlanganisela ye-fiber-reinforced resin matrix kanye ne-fiberglass ingamelana nemithwalo emikhulu nezingcindezi, ngakho-ke okubalulekile kuyaphumelela ezicini zemishini.
(3) Ukumelana nokugqwala:I-GFRP inokumelana nokugqwala okuhle kakhulu futhi ayingenwa kalula yimithombo yezindaba ebolayo efana ne-asidi, i-alkali, namanzi anosawoti. Lokhu kwenza izinto ezitholakala ezindaweni ezihlukahlukene ezinokhahlo zibe yinzuzo enkulu, njengasemkhakheni wobunjiniyela basolwandle, okokusebenza kwamakhemikhali, namathangi okugcina.
(4) Izakhiwo ezinhle zokuvikela:I-GFRP inezinto ezinhle zokuvikela ukushisa futhi ingakwazi ukuhlukanisa ngempumelelo i-electromagnetic kanye ne-thermal energy conduction. Lokhu kwenza izinto ezisetshenziswa kabanzi emkhakheni wobunjiniyela bukagesi kanye nokuhlukaniswa okushisayo, njengokwenziwa kwamabhodi wesekethe, imikhono evikelayo, nezinto zokuhlukanisa ezishisayo.
(5) Ukumelana nokushisa okuhle:I-GFRP ineukumelana nokushisa okuphezulufuthi iyakwazi ukugcina ukusebenza okuzinzile ezindaweni ezinezinga lokushisa eliphezulu. Lokhu kuyenza isetshenziswe kabanzi ku-aerospace, i-petrochemical, kanye nezinkambu zokuphehla amandla, njengokwenza izindwani zenjini ye-turbine yegesi, ukuhlukaniswa kwesithando somlilo, kanye nezingxenye zemishini yemishini yamandla ashisayo.
Kafushane, i-GFRP inezinzuzo zamandla aphezulu, i-lightweight, ukumelana nokugqwala, izakhiwo ezinhle zokuvikela ukushisa, nokumelana nokushisa. Lezi zakhiwo ziyenza ibe yinto esetshenziswa kabanzi embonini yokwakha, i-aerospace, izimoto, amandla, kanye nezimboni zamakhemikhali.
