Ukufakwa kwe-FRP kuyindlela evamile nebaluleke kakhulu yokulawula ukugqwala ekwakhiweni okunzima kokulwa nokugqwala. Phakathi kwazo, i-FRP yokubeka ngesandla isetshenziswa kabanzi ngenxa yokusebenza kwayo okulula, ukulula kanye nokuguquguquka. Kungashiwo ukuthi indlela yokubeka ngesandla ihlanganisa ngaphezu kuka-80% wesilinganiso sokwakhiwa kwe-FRP yokulwa nokugqwala. I-resin, i-fiber kanye ne-powder fiber "yezinto ezintathu ezinkulu" ku-FRP ebekwe ngesandla iyisakhiwo se-FRP, esisekela amandla ohlelo lwe-FRP, futhi siyingxenye ebalulekile yokuqaphela umphumela wesikhathi eside wokulwa nokugqwala kwe-FRP.
Ngokusho komehluko wendawo egqwalisayo kanye nendawo ephakathi, izinto zokwakha ze-FRP nazo zizoshintsha. Ukukhethwa kwezinto ezinemibandela ngesikhathi sokwakha kuyisici esibalulekile ukuqinisekisa ukuthi umkhiqizo we-FRP oqediwe ungazivumelanisa nendawo egqwalisayo kanye nokuqina kwayo. Ngakho-ke, ukukhethwa kwezinto zokuqinisa ze-FRP kumele kunqunywe ngaphambi kokwakhiwa. Isibonelo, izinto zokuqinisa ezimelelwa yi-fiber yengilazi yizinto ezivame kakhulu ze-fiber, ezingamelana nokugqwala kwe-asidi; noma kunjalo, azimelani ne-hydrofluoric acid kanye nokugqwala kwe-phosphoric acid eshisayo. Sebenzisa i-polyester, i-polypropylene kanye nezinye indwangu ye-fiber yemvelo kanye ne-felt, ungakhetha futhi ukusebenzisa ilineni noma i-gauze ekhishwe amafutha, futhi eminye imikhiqizo ye-FRP idinga ukumelana nokugqwala kanye nokuqhuba, ungakhetha izinto ze-carbon fiber. Ngamafuphi, ukukhethwa kwe-fiber eqinisiwe ye-FRP ebekwe ngesandla kuyiphuzu lekhono nolwazi okufanele lufundwe ubuchwepheshe bokulwa nokugqwala kanye nabaklami.
Emikhiqizweni ye-FRP enamathiselwe, iningi lemicu yokuqinisa yimicu yengilazi, kungaba yindwangu, i-felt noma intambo. Isizathu esiyinhloko ukuthi ngaphezu kwentengo, inezici ezinhle kakhulu ezilandelayo:
01 Ukumelana namakhemikhali
Imicu yendwangu ye-fiberglass engaphili ngeke ibole, ibumbe noma yonakale. Imelana nama-asidi amaningi ngaphandle kwe-hydrofluoric kanye ne-hot phosphoric acid.
02 Uzinze ngosayizi
Izindwangu zefayibha yengilazi ezisetshenziselwa ukwenza izindwangu zengilazi azinwebeki noma azinciphi ngenxa yezinguquko ezimweni zomkhathi. Ukwelulwa okujwayelekile lapho kuphuka kungu-3-4%. Isilinganiso esimaphakathi sokwanda kokushisa okuqondile kwengilazi ye-E singu-5.4 × 10-6 cm/cm/°C.
03 Ukusebenza kahle kokushisa
Izindwangu ze-fiberglass zine-coefficient ephansi yokwanda kokushisa kanye nokuqhuba okuphezulu kokushisa. I-fiberglass isusa ukushisa ngokushesha kune-asbestos noma imicu yemvelo.
04 Amandla aphezulu okudonsa
Intambo ye-fiberglass inesilinganiso esiphakeme samandla nesisindo. Iphawundi lentambo ye-fiberglass liqine kabili kunentambo yensimbi. Amandla okwakha amandla aqondene noma aqondene nezinhlangothi ezimbili endwangu akhulisa kakhulu ukuguquguquka kwemikhiqizo yokusetshenziswa kokugcina.
05 Ukumelana nokushisa okuphezulu
Imicu yengilazi engaphili ayishi futhi empeleni ayivikelwe emazingeni okushisa aphezulu okubhaka nokulungisa avame ukutholakala ekucutshungulweni kwezimboni. I-Fiberglass izogcina cishe u-50% wamandla ayo ku-700°F kanye no-25% ku-1000°F.
06 I-hygroscopicity ephansi
Izindwangu ze-fiberglass zenziwe ngemicu engenazimbobo ngakho-ke zimunca umswakama omncane kakhulu.
07 Ukuvikela okuhle kukagesi
Amandla aphezulu e-dielectric kanye nokungaguquguquki kwe-dielectric okuphansi, kanye nokumuncwa kwamanzi okuphansi kanye nokumelana nokushisa okuphezulu, kwenza izindwangu ze-fiberglass zibe zinhle kakhulu ekuvikeleni ugesi.
08 Ukuguquguquka komkhiqizo
Izintambo ezincane kakhulu ezisetshenziswa ezintanjeni ze-fiberglass, izinhlobo ezahlukene zobukhulu bezintambo kanye nokwakheka kwazo, izinhlobo ezahlukene zokulukwa, kanye nokuqedwa okuningi okukhethekile kwenza izindwangu ze-fiberglass zibe usizo ezinhlobonhlobo zokusetshenziswa kwezimboni.
09 intengo ephansi ephansi
Izindwangu ze-fiberglass zingawenza umsebenzi futhi zifana ngezindleko nezindwangu ze-fiber zokwenziwa nezemvelo.
Ngakho-ke, i-glass fiber iyinto efanelekile yokuqinisa i-FRP, engabizi kakhulu, futhi elula ukuyisebenzisa. Ingenye yezinto ezisetshenziswa kakhulu phakathi kwezinto eziningi zokuqinisa okwamanje.
