FRP, eyaziwa nangokuthi i-fiber-reinforced polymer, iyinhlanganisela yezinto ezakhiwe imicu eqinisiwe kanye ne-matrix resin. Inhloso yayo eyinhloko ukuxazulula inkinga yokugqwala kwensimbi eyenza buthaka izakhiwo zekhonkolo eziqinisiwe zendabuko.
I-FRP inezinhlobonhlobo zezinhlelo zokusebenza ezimbonini ezahlukene ngenxa yekhono layo lokwenza ngokwezifiso izinhlobonhlobo zama-resin ayisisekelo njenge-polyester engasetshenzisiwe, i-epoxy, i-vinyl ester, ne-polyurethane. Lawa ma-resin anezakhiwo eziyingqayizivele ezenza i-FRP ihlangabezane nezinhlobonhlobo zezidingo.
Ngaphezu kwalokho, i-FRP futhi isebenzisa izinhlobo ezahlukene zokuqinisa imicu, okuhlanganisa i-fiber yengilazi, i-basalt fiber kanye ne-carbon fiber, ngayinye enezakhiwo eziyingqayizivele ezifana namandla aphezulu, ukumelana nokugqwala nokuqina. Ngenxa yalokho, i-FRP iba yinto eguquguqukayo nephumelelayo yokwakha kanye nezinhlelo zokusebenza zesakhiwo.

Ukushintsha kwe-FRPibhekwa njengenye indlela esebenzayo kune-rebar yensimbi yendabuko kumaphrojekthi wokwakha futhi iya ngokuya idume ngenxa yezinzuzo zayo eziyingqayizivele.
Enye yezimbangela eziyinhloko zokuwohloka kwengqalasizinda ukugqwala kokuqiniswa kwensimbi kukhonkolo. Lokhu akufinyezi nje ukuphila kukakhonkolo kuphela, kungaholela ekwenyukeni kwezindleko zokulungisa kanye nezingozi zokuphepha. Kodwa-ke, ngokusebenzisa i-fiberglass rebar, inkinga yokugqwala ingaqedwa ngokuphelele.
Ngokwesibonelo,IGRECHO i-fiberglass rebar yakhiwe ngokuphelele ngezinto ezingezona ezensimbi, enikeza ikhambi elihlala njalo elincintisana ngokwezindleko nensimbi. Ukwengeza, ukungena kwayo kwe-electromagnetic kuyenza ifaneleke ikakhulukazi ukuthunyelwa ezindaweni ezibucayi.
Okulandelayo izici kanye nokusetshenziswa kwama-rebar e-FRP:
Ukumelana Nokugqwala:
Enye yezinzuzo eziyinhloko ze-FRP rebar ukumelana nokugqwala kwayo. Ngokungafani nensimbi, esengozini yokugqwala kanye nokugqwala lapho ivezwe kumswakama, i-rebar ye-FRP ayigqwali. Lokhu kuyenza ilungele izakhiwo ezindaweni zasolwandle, izindawo ezisogwini kanye nezindawo ezinomswakama ophezulu.
Amandla Aphezulu, Ayisindi:
I-rebar ye-FRP inesilinganiso esiphezulu samandla nesisindo, okusho ukuthi inesisindo esingaphansi kwensimbi kuyilapho igcina amandla afanayo noma amakhulu nakakhulu. Lokhu kwenza ukuthumela, ukuphatha nokufaka kube lula. Naphezu kwesisindo sayo esilula, i-rebar ye-FRP inamandla amahle kakhulu okuqina.
Okungaqhubeki:
I-FRP rebar ayihambisi, okusho ukuthi ayiwuhambisi ugesi. Le ndawo iyenza ifanelekele ukusetshenziswa ezakhiweni ezinjengamabhuloho kanye nokufakwa kukagesi, lapho ukuba khona kwezinto zokuqhuba kungase kubangele izingozi zokuphepha.
Ukuqina:
I-FRP rebar inempilo ende yesevisi ngenxa yokumelana nezici ezihlukahlukene zemvelo. Akuthintwa imisebe ye-UV, ukushintshashintsha kwezinga lokushisa noma imijikelezo yokuncibilika kweqhwa. Lezi zakhiwo zenza i-FRP rebar ifanelekele amaphrojekthi engqalasizinda lapho ukuqina kuyisidingo esibalulekile.
I-Non-magnetic ne-non-conductive:
I-FRP rebar ayinazibuthe futhi ayiqhubeki, okuyenza ilungele izindawo ezibucayi lapho ukuphazamiseka kukazibuthe kudinga ukuncishiswa, njengezibhedlela, izikhungo ze-MRI nezikhungo zedatha.
Izicelo zemigoqo yensimbi ye-FRP zifaka:
Ingqalasizinda yomphakathi:
Izindleko zamasheya FRPzisetshenziswa ekwakhiweni kwamabhuloho, imigwaqo emikhulu, imigudu nezakhiwo zokupaka ukuze kuqiniswe ukhonkolo nokuqinisekisa ukuqina kwesikhathi eside ezimweni ezinzima zemvelo.
Izakhiwo Zasolwandle:
Ama-rebar e-FRP asetshenziswa kakhulu ezakhiweni zasolwandle njengamachweba, izikhumulo zemikhumbi, izikhumulo zemikhumbi kanye nezakhiwo ezingasemanzini lapho ukuchayeka emanzini anosawoti, umswakama kanye nezinto ezibolayo kuphezulu.
Ukwakha:
I-FRP rebar iya ngokuya isetshenziswa ezakhiweni zokuhlala nezohwebo ukuqinisa izakhiwo zikakhonkolo ezifana nama-slabs, amakholomu, izindonga nezisekelo.
Ukulungiswa Kwesakhiwo:
I-rebar ye-FRP isetshenziselwa ukulungisa nokuqinisa izakhiwo ezikhona ezihlushwa ukugqwala noma ezidinga ukuqiniswa okwengeziwe.
Izindawo Zokuhlanza Amanzi Angcolile:
Ama-rebar e-FRP asetshenziswa kakhulu ezitshalweni zokuhlanza amanzi angcolile ezichayeka ku-acidic kanye nezinto ezibolayo.
Izicelo Zochwepheshe:
Ama-rebar e-FRP angasetshenziswa ezinhlelweni zokusebenza ezinjengokufakwa kukagesi, izibhedlela, izikhungo ze-MRI kanye nezikhungo zedatha ngenxa yezindawo zazo ezingezona uzibuthe nezingezona u-conductive.
Sekukonke, i-rebar ye-FRP inikezela ngezinzuzo eziningi, okubandakanya ukumelana nokugqwala, amandla aphezulu, ukuqina, kanye nezakhiwo ezingaqhubeki, okuyenza ibe yisixazululo esisebenza ngezindlela eziningi nesisebenzayo sezidingo ezahlukahlukene zokwakha.
KUNGANI UKHETHA FRP REBAR
Isinqumo sokukhetha ibha ye-FRP sidinga ukucatshangelwa ngokucophelela kwezici ezifana nekhwalithi, ukusebenza kanye nezindleko. Ukuthola ibhalansi phakathi kwalokhu okuguquguqukayo kubalulekile lapho wenza ukukhetha unolwazi. Ngeshwa, abantu bavame ukubeka phambili izinzuzo ezisheshayo belahlekelwa izinzuzo zesikhathi eside ezingazuzwa. Uma sithatha izinqamuleli namuhla futhi siziba ukuhlela okuphusile, nakanjani sizosebenzisa imali eningi ekubhidlizeni okuphindaphindiwe nokwakha kabusha esikhathini esizayo. Nakuba izindleko zokuqala ze-FRP rebar zivame ukuba phezulu,izinzuzo zezindleko zesikhathi eside ukuqina kwayo kanye nokugcinwa kokunakekelwa okuncishisiwe kudlula kude utshalomali lwasekuqaleni. Ukuhlela okunesibopho manje kubalulekile, okuhlanganisa nokuhlola ngokucophelela izibikezelo zokuphila kwesevisi, okubalulekile kubunjiniyela benani obuhlala isikhathi eside. Ukwakha ingqalasizinda eqinile yezwe lethu kanye nokwakha amakhaya ahlala isikhathi eside kudinga ukusetshenziswa kwezinto ezisezingeni eliphezulu nezisebenzayo.
Uma ucabangela i-carbon footprint yakho, kubalulekile ukuqaphela ukuthi ukukhiqizwa kwensimbi kunomthelela omkhulu kakhulu kwezemvelo kunokukhiqizwa kwe-fiberglass rebar. Lokhu kuyiqiniso ngisho nangaphandle kokucabangela i-carbon footprint eyengeziwe edalwe ukubhidlizwa okuphindaphindiwe nokubuyiselwa.
Ngokuthatha indlela yokubheka phambili futhi sicabangele izinzuzo ezingase zivele esikhathini esizayo, singaqinisekisa ukuthi izenzo zethu ziholela emiphumeleni eqhubekayo nehlala njalo.
