I-FRP lining yindlela eqhelekileyo neyona ibalulekileyo yokulawula ukugqwala ekwakheni okunzima okulwa nokugqwala. Phakathi kwazo, i-FRP yokubeka ngesandla isetyenziswa kakhulu ngenxa yokusebenza kwayo okulula, ukulula kunye nokuguquguquka. Kunokuthiwa indlela yokubeka ngesandla ithatha ngaphezulu kwe-80% yomlinganiselo wokwakhiwa kwe-FRP yokulwa nokugqwala. I-resin, ifayibha kunye nefayibha yomgubo kwi-FRP ebekwe ngesandla zizinto ze-FRP, ezixhasa amandla enkqubo ye-FRP, kwaye ziyinxalenye ebalulekileyo yokufezekisa isiphumo sexesha elide sokulwa nokugqwala kwe-FRP.

Ngokomahluko wendalo ekonakalisayo kunye nendawo ephakathi, izinto eziyinxalenye ye-FRP nazo ziya kutshintsha. Ukukhethwa kwezinto ezinemiqathango ngexesha lokwakha yinto ebalulekileyo ukuqinisekisa ukuba imveliso ye-FRP egqityiweyo iyakwazi ukuzivumelanisa nendalo ekonakalisayo kunye nokuqina kwayo. Ke ngoko, ukukhethwa kwezinto zokuqinisa i-FRP kufuneka kumiselwe ngaphambi kokwakhiwa. Umzekelo, izinto zokuqinisa ezimele i-fiber yeglasi zezona zinto zixhaphakileyo zefayibha, ezinokumelana nokugqwala kwe-asidi eninzi; nangona kunjalo, azixhathisi kwi-hydrofluoric acid kunye nokugqwala kwe-phosphoric acid eshushu. Sebenzisa i-polyester, i-polypropylene kunye nezinye ilaphu le-organic fiber kunye ne-felt, ungakhetha ukusebenzisa ilinen okanye i-gauze ehlanjululweyo, kwaye ezinye iimveliso ze-FRP zifuna ukumelana nokugqwala kunye nokuqhuba, ungakhetha izinto ze-carbon fiber. Ngamafutshane, ukukhethwa kwe-hand lay-up FRP eqinisiweyo fiber yingongoma yesakhono nolwazi ekufuneka iteknoloji yokulwa nokugqwala ibe lulwazi.

Kwiimveliso ze-FRP ezincanyathiselweyo, uninzi lweefayibha zokuqinisa ziifayibha zeglasi, nokuba zelaphu, ifeliti okanye intambo. Isizathu esiphambili kukuba ukongeza kwixabiso, ikwanazo ezi mpawu zilandelayo zibalaseleyo:
01 Ukumelana neekhemikhali
Iifayibha zelaphu ze-fiberglass ezingaphiliyo aziyi kubola, zibune okanye ziwohloke. Ziyakwazi ukumelana nee-asidi ezininzi ngaphandle kwe-hydrofluoric kunye ne-hot phosphoric acid.
02 Uzinzo ngokwemilinganiselo
Iintambo zefayibha yeglasi ezisetyenziselwa ukwenza amalaphu eglasi azoluli okanye azinciphi ngenxa yotshintsho kwiimeko zomoya. Ukwandiswa okuqhelekileyo ngexesha lokuqhekeka yi-3-4%. I-coefficient ephakathi yokwandiswa kobushushu obuhamba ngomgca weglasi ye-E yi-5.4 × 10-6 cm/cm/°C.
03 Ukusebenza kakuhle kobushushu
Amalaphu e-fiberglass anomlinganiselo ophantsi wokwandiswa kobushushu kunye nokuqhuba okuphezulu kobushushu. I-Fiberglass isusa ubushushu ngokukhawuleza kune-asbestos okanye iifayibha ze-organic.
04 Amandla aphezulu okuxinana
Intambo yefayibha inomlinganiselo ophezulu wokuqina-ubunzima. Iponti enye yentambo yefayibha inamandla aphindwe kabini kunentambo yentsimbi. Amandla okwenza uyilo lokuqina oluya kwicala elinye okanye oluya kwicala elinye kwilaphu andisa kakhulu ukuguquguquka kweemveliso ezisetyenziswa ekugqibeleni.
05 Ukumelana nobushushu obuphezulu
Iifayibha zeglasi ezingaphiliyo azitshi kwaye azinawo amandla obushushu aphezulu okubhaka nokuphilisa adla ngokufunyanwa xa kusetyenzwa kwimizi-mveliso. I-Fiberglass iya kugcina malunga ne-50% yamandla ayo kwi-700°F kunye ne-25% kwi-1000°F.
06 Ukungabi namanzi aneleyo
Imisonto ye-fiberglass yenziwe ngemisonto engenamibhobho kwaye ngenxa yoko ayinamanzi amaninzi.
07 Ubushushu obuhle bombane
Amandla aphezulu e-dielectric kunye ne-dielectric constant ephantsi, kunye nokufunxwa kwamanzi okuncinci kunye nokumelana nobushushu obuphezulu, kwenza amalaphu e-fiberglass abe ngcono kakhulu ekugqumeni umbane.
08 Ukuguquguquka kwemveliso
Iintambo ezincinci kakhulu ezisetyenziswa kwiintambo zefiberglass, ubungakanani kunye nokwakheka kweentambo ezahlukeneyo, iintlobo ezahlukeneyo zokuluka, kunye neendlela ezininzi ezikhethekileyo zenza amalaphu efiberglass abe luncedo kwiintlobo ngeentlobo zemisebenzi yemizi-mveliso.
09 ixabiso eliphantsi ixabiso eliphantsi
Amalaphu e-fiberglass anokwenza umsebenzi kwaye axabisa kakhulu kuneefayibha ezenziwe ngokwenziwa kunye nezendalo.

Ngoko ke, ifayibha yeglasi yeyona nto ifanelekileyo yokuqinisa i-FRP, engabizi kakhulu, kwaye kulula ukuyisebenzisa. Yenye yezona zinto zisetyenziswa kakhulu phakathi kwezinto ezininzi zokuqinisa okwangoku.
