I-FRP lining iyindlela evamile futhi ebaluleke kakhulu yokulawula ukugqwala ekwakhiweni kwe-anti-corrosion esindayo.Phakathi kwazo, i-FRP yokubeka izandla isetshenziswa kabanzi ngenxa yokusebenza kwayo okulula, ukunethezeka nokuguquguquka.Kungashiwo ukuthi indlela yokubeka isandla yenza ngaphezu kuka-80% wokwakhiwa kwe-FRP anti-corrosion.isilinganiso."Izinto ezintathu ezinkulu" i-resin, i-fiber kanye ne-powder fiber ku-FRP ebekwe ngesandla iwuhlaka lwamathambo e-FRP, olusekela amandla ohlelo lwe-FRP, futhi luyingxenye ebalulekile yokuqaphela umphumela wesikhathi eside wokulwa nokubola kwe-FRP.
Ngokomehluko wendawo ebolayo nendawo ephakathi, izinto zokwakha ze-FRP nazo zizoshintsha.Ukukhethwa kwempahla enemibandela ngesikhathi sokwakhiwa kuyisici esibalulekile sokuqinisekisa ukuthi umkhiqizo oqediwe we-FRP uyakwazi ukuzivumelanisa nendawo ebolayo kanye nokuqina kwawo.Ngakho-ke, ukukhethwa kwezinto zokuqinisa i-FRP kufanele kunqunywe ngaphambi kokwakhiwa.Isibonelo, izinto zokuqinisa ezimelelwe i-glass fiber yizinto ezivame kakhulu ze-fiber, ezingamelana nokugqwala kwe-asidi;kodwa-ke, azimelani ne-hydrofluoric acid kanye ne-hot phosphoric acid corrosion.Sebenzisa i-polyester, i-polypropylene kanye nezinye indwangu ye-fiber ephilayo futhi uzizwe, ungakhetha futhi ukusebenzisa ilineni noma i-gauze e-degreased, kanti eminye imikhiqizo ye-FRP idinga ukumelana nokugqwala kanye ne-conductivity, ungakhetha izinto ze-carbon fiber.Ngamafuphi nje, ukukhethwa kwe-FRP reinforced fibre yokubeka isandla kuyiphuzu lekhono nolwazi okufanele ubuchwepheshe bokulwa nokugqwala kanye nabaklami baphumelele.
Emikhiqizweni ye-FRP enamathiselwe, imicu eminingi eqinisayo imicu yengilazi, noma ngabe indwangu, inzwa noma intambo.Isizathu esiyinhloko ukuthi ngaphezu kwesici senani, futhi inezici ezilandelayo ezinhle kakhulu:
01 Ukumelana namakhemikhali
Imicu ye-Inorganic fiberglass textile ngeke ibole, ikhunte noma yonakale.Ziyakwazi ukumelana nama-asidi amaningi ngaphandle kwe-hydrofluoric ne-hot phosphoric acid.
02 Izinzile ngokwezinga
Izintambo zefibre yengilazi ezisetshenziselwa ukwenza izindwangu zengilazi azinwebeki noma zishwabane ngenxa yezinguquko ezimweni zomoya.Ukwelulwa okujwayelekile ngesikhathi sekhefu kungu-3-4%.Isilinganiso esimaphakathi sokunwetshwa kwe-thermal coefficient yenqwaba yengilazi engu-E ngu-5.4 × 10-6 cm/cm/°C.
03 Ukusebenza okuhle kwe-thermal
Izindwangu ze-Fiberglass zine-coefficient ephansi yokwanda okushisayo kanye nokuhamba okuphezulu kokushisa.I-Fiberglass ichitha ukushisa ngokushesha kune-asbestos noma imicu yemvelo.
04 Amandla aphezulu wokushuba
Intambo ye-Fiberglass inenani eliphezulu lamandla nesisindo.Iphawundi lentambo ye-fiberglass iqine ngokuphindwe kabili kunocingo lwensimbi.Amandla okwenza unidirectional amandla angaqondile noma amabili endwangu akhulisa kakhulu ukuguquguquka kwemikhiqizo yokusetshenziswa ekugcineni.
05 Ukumelana nokushisa okuphezulu
Imicu yengilazi ye-Inorganic ayishi futhi ivikelekile ekubhakeni okuphezulu kanye namazinga okushisa avame ukuhlangana nawo ekucutshungulweni kwezimboni.I-Fiberglass izogcina cishe u-50% wamandla ayo ku-700°F no-25% ku-1000°F.
06 I-hygroscopicity ephansi
Izintambo ze-Fiberglass zenziwe ngezintambo ezingenayo i-porous ngakho-ke zinokumunca umswakama ophansi kakhulu.
07 Ukufakwa kahle kukagesi
Amandla e-dielectric aphezulu kanye ne-dielectric engaguquki ephansi, kanye nokumunca amanzi aphansi kanye nokumelana nezinga lokushisa eliphezulu, kwenza izindwangu ze-fiberglass zibe zinhle kakhulu ekufakweni kukagesi.
08 Ukuguquguquka komkhiqizo
Imicu emihle kakhulu esetshenziswa ezintanjeni ze-fiberglass, izinhlobonhlobo zosayizi bezintambo kanye nokucushwa, izinhlobo ezihlukene zokuluka, kanye nokuqedwa okuningi okukhethekile kwenza izindwangu ze-fiberglass zibe usizo ekusetshenzisweni okubanzi kokuphela kwezimboni.
09 intengo ephansi
Izindwangu ze-fiberglass zingenza umsebenzi futhi ziqhathaniswa nezindleko nezindwangu ze-fiber zokwenziwa nezemvelo.
Ngakho-ke, i-glass fiber iyindlela efanelekile yokuqinisa isandla ye-FRP, eyongayo, engabizi, futhi kulula ukuyisebenzisa.Ingenye yezinto ezisetshenziswa kakhulu phakathi kwezinto eziningi zokuqinisa okwamanje.
