Izinto ezidityanisiweyo ze-polymer eziqiniswe ngefayibha yeglasi (GFRP)Zisemgangathweni xa zakhiwe kuba zinomlinganiselo ophezulu wokuqina xa zithelekiswa nobunzima, azigayi mzimba, kwaye ziyakwazi ukusetyenziswa ngeendlela ezahlukeneyo.

Okokuqala, i-GFRP isetyenziswa kakhulu kulwakhiwo lokwenyani ukwenza izinto eziphambili ezixhasa umthwalo ezifana neebhama kunye neekholamu, kunye neepaneli zomgangatho. Ukusetyenziswa kweepateni zefayibha yeglasi ye-multi-axial kunye neeresini eziguquguqukayo kuvumela izixhobo ze-GFRP ukuba zinike amandla abalaseleyo okuxinana nokugoba. Umzekelo, imivalo eqiniswe nge-GFRP inokunciphisa ubukhulu obunqamlezileyo ngelixa igcina amandla okuthwala umthwalo, ngaloo ndlela yandisa indawo yangaphakathi esebenzisekayo. Kwizakhiwo zomgangatho, iipropati ezibalaseleyo zokugoba zamaphepha e-GFRP zinokuphucula ukuqina kwesakhiwo, zinciphise ukuphambuka okuphakathi, kwaye zandise ubomi benkonzo.

Okwesibini, kwishishini lokwakha, i-GFRP ithatha indawo yokuqinisa intsimbi yendabuko kancinci kancinci ukuphucula ukuqina kwesakhiwo kunye nokumelana nokugqwala. Ukuqinisa intsimbi yendabuko kulula ukugqwala kwiindawo ezifumileyo, ezitshizwa ngetyuwa, okanye kwiindawo ezineekhemikhali, ngelixa i-GFRP ibonisa ukumelana nokugqwala okugqwesileyo. Uvavanyo lubonisa ukuba nakwiindawo ezinetyuwa eninzi,I-GFRPigcina amandla ayo angaphezu kwama-90% emva kweeyure ezili-1000 zovavanyo lokugqwala ngokukhawuleza. Oku kwenza i-GFRP ibe yinto ebalulekileyo yokwakha kwiibhulorho zaselunxwemeni, kwiindawo zokuphela kwezibuko, nakwizityalo zoshishino. Ngaphezu koko, i-coefficient ye-GFRP yokwandiswa kobushushu isondele kwekhonkrithi, ithintela uxinzelelo loxinzelelo ngenxa yotshintsho lobushushu kwaye yandisa ubomi bezakhiwo zekhonkrithi.

Iindawo ze-GFRP zikwasetyenziswa kakhulu kwiindawo ezinobungozi kakhulu, njengeziseko zeetanki kwizityalo zeekhemikhali, iziseko zamaqonga olwandle, kunye neendonga zamachibi kwizityalo zamanzi amdaka. Ezi ndawo zichaphazeleka ngamanqanaba aphezulu e-asidi, iziseko, kunye nezinye izinto ezinobungozi ixesha elide. Ngelixa izinto eziqhelekileyo zibola ngokulula, i-GFRP ayichaphazeleki lula kuhlaselo lweekhemikhali. Izibalo zibonisa ukuba emva kokuvezwa kwisisombululo se-asidi seenyanga ezi-6, esine-pH ye-3, i-GFRP iya kuba ne-95% yamandla ayo okuqala okugoba, ngaloo ndlela ibonelela ngesiqinisekiso sexesha elide kwizakhiwo ezikwiindawo ezinobundlobongela kunye neendleko eziphantsi zokugcinwa kunye nokutshintshwa. Iziseko zophuhliso ezigugileyo nazo zifuna ukulungiswa nokuqiniswa, njengeebhulorho ezininzi zendlela kunye nezakhiwo zepropathi. I-GFRP sisixhobo esigqibeleleyo sokuqinisa kuba siqinile, sikhaphukhaphu, kwaye sibopha kakuhle ikhonkrithi. Kwiiprojekthi zokuqinisa iibhulorho, inxalenye yoxinzelelo lweebhari idla ngokuncamathiselwa ngamaphepha e-GFRP ukuze iwaqinise ekugobeni. Iibhari zekhonkrithi eziqinisiweyo ze-GFRP zinokuqiniswa ukuya kuthi ga kwi-20-50%. Xa kulungiswa imijelo, iimveliso ze-GFRP mesh zisetyenziswa ekuqiniseni i-lining ukuze kuqiniswe ilitye elijikelezileyo kwaye lenze lizinze kwaye lingagugi. Ukufakelwa kwe-lining ye-GFRP kukhawuleza kwaye akuchaphazeli kakhulu isakhiwo esikhoyo kwaye ke ngoko kufanelekile ukulungiswa okungxamisekileyo kwezakhiwo ezindala kunye neebhulorho.

Okokugqibela, kubunjineli beebhulorho kunye neetonela, kwiibhulorho ezindala, ezigubungela umphezulu wezinto ezithwala umthwalo ngeAmaphepha okanye iipleyiti zeGFRP, kusetyenziswa i-epoxy resin ekhethekileyo yokubopha ngokuqinileyo, kunokuphucula amandla okuthwala umthwalo kwaye kunciphise inkqubo yokwaluphala kwesakhiwo. Kubunjineli bemigudu, iigridi ze-GFRP zisebenza kunye nekhonkrithi ukwenza isakhiwo esixhasayo esidibeneyo, siphucula ngempumelelo ukumelana nokucheba kwemigudu kunye nokuzinza kwexesha elide, ngakumbi kwiindawo ezisengozini yokunyikima.
