I-downsides ye-fiberglass rebar
I-Fiberglass rebar (I-GFRP, noma ipulasitiki eqiniswe ngefayibha yengilazi) iyinhlanganisela yezinto, ehlanganisa imicu yengilazi nenhlaka, esetshenziswa njengenye indlela yokuqinisa insimbi evamile kwezinye izinhlelo zokusebenza zesakhiwo. Naphezu kwezinzuzo zayo eziningi, kukhona ukungalungi:
1. ukumelana ne-alkali okubi kakhulu:imicu yengilazi isengozini yokuguguleka ezindaweni ezine-alkaline, kuyilapho izindawo zikakhonkolo ngokuvamile zine-alkaline, ezingase zithinte izakhiwo zokubopha kanye nokuqina kwesikhathi eside kwe-fiberglass eqinisa imigoqo kukhonkolo.
2. Amandla okugunda aphansi:Imigoqo yokuqinisa i-Fiberglass babe namandla okugunda aphansi uma kuqhathaniswa nezinsimbi ezivamile zensimbi, ezikhawulela ukusetshenziswa kwazo ezingxenyeni zesakhiwo lapho kudingeka ukumelana okuphezulu kwe-shear.
3. I-ductility engalungile:I-Fiberglassrebar awazona ama-ductile njengemigoqo yensimbi evamile, okusho ukuthi angakwazi ukumelana nokuguquguquka okuncane ngaphambi kokuba afinyelele amandla awo okugcina, futhi angase angabi inketho efanelekile kweminye imiklamo yokuzamazama komhlaba.
4. Ukusebenza kabi emazingeni okushisa aphezulu:Amandla wei-fiberglassrebar kuncipha kakhulu ezindaweni zokushisa okuphezulu, okukhawulela ukusetshenziswa kwazo ezinhlelweni lapho zingachayeka khona emazingeni okushisa aphezulu.
5. Izinkinga zezindleko: Ngenkathi i-fiberglassrebar kungaba ukonga izindleko kwezinye izimo, kwezinye zingabiza kakhulu kunemigoqo evamile yokuqinisa ngenxa yesimo esiyingqayizivele sezinto ezibonakalayo, ukukhiqizwa nokufakwa.
6. Ukumiswa kanye nokucaciswa komklamo: Ukusetshenziswa kweimigoqo yokuqinisa i-fiberglass yintsha uma iqhathaniswa nokuqiniswa kwensimbi evamile, ngakho-ke ukumiswa okuhlobene nokucaciswa kwemiklamo kungase kungavuthwa ngokwanele, futhi abaklami bangase babhekane nemikhawulo mayelana nemininingwane kanye neziqondiso zokusetshenziswa kwabo.
7. Amasu okwakha:Ukufakwa nokwakhiwa kwei-fiberglassrebar zidinga amakhono akhethekile nezinyathelo zokuphepha, ezingase ziholele ekwandeni kobunzima bokwakha kanye nezindleko.
8. Izinkinga zokumisa imakhenikha: I-anchoring yei-fiberglassrebar ingaba yinkimbinkimbi kakhulu kunaleyo yemigoqo yokuqinisa evamile, edinga imiklamo ekhethekile yokubambelela nezindlela zokwakha.
Naphezu kwalezi zihibe,ingilazi fiber rebar ihlala iyindlela ekhangayo kwezinye izinhlelo zokusebenza ezithile, ikakhulukazi lapho kudingeka khona izinto zokwakha ezingezona uzibuthe, ukumelana nokugqwala noma ezingasindi.
Inzuzo ye-fiberglass rebar
I-GFRP inezinzuzo ezilandelayo ngaphezu kwamabha ensimbi evamile (imvamisa amabha ensimbi ye-carbon):
1. Ukumelana nokugqwala:Amabha we-GFRP ungagqwali, ngakho-ke zihlala isikhathi eside ezindaweni ezinokhahlo njengasolwandle, ukugqwala kwamakhemikhali noma izimo ezinomswakama ophezulu.
2. Okungewona uzibuthe:Frp ibha akuzona ezizibuthe, okuzenza zibe usizo ezimweni lapho kudingeka khona izinto ezingezona kazibuthe, njengamagumbi e-MRI ezibhedlela noma eduze kwemishini yokuhlola i-geological.
3. Ingasindi:I-fiberglass ekhanyayo ibe nokuminyana okuphansi kakhulu kunemigoqo yensimbi evamile, okwenza kube lula ukuyiphatha nokuyifaka ngesikhathi sokwakha kuyilapho inciphisa isisindo sesakhiwo sonke.
4. Ukufakwa kukagesi:Imigoqo ye-polymer eqinisiwe ye-glass fibre zingama-insulators kagesi, ngakho-ke zingasetshenziswa ezakhiweni ezidinga ukufakelwa ugesi, njengemibhoshongo yezokuxhumana noma izakhiwo zokusekela izintambo zikagesi.
5. Ukuguquguquka komklamo:Amabha we-GFRP kungenziwa ngokwezifiso ngokuma nosayizi njengoba kudingeka, ukunikeza abaklami inkululeko enkulu yokuklama.
6. Ukuqina: Ngaphansi kwezimo ezifanele,imigoqo yokuqinisa i-fiberglass inganikeza ukuqina kwesikhathi eside, ukunciphisa izindleko zokulungisa nokufaka esikhundleni.
7. Ukumelana nokukhathala: Izinhlobo ze-fiberglass babe nokumelana nokukhathala okuhle, okusho ukuthi bagcina ukusebenza kwabo ngaphansi kwemithwalo ephindaphindiwe, okubenza bafaneleke izakhiwo ezingaphansi kwemithwalo yamabhayisikili, njengamabhuloho nemigwaqo emikhulu.
8. I-coefficient ephansi yokunwetshwa kwe-thermal:Izinhlobo ze-fiberglass babe ne-coefficient ephansi yokwandisa okushisayo, okubanikeza ukuzinza okungcono kwe-dimensional ezindaweni ezinezinguquko ezinkulu zokushisa.
9. Isembozo sikakhonkolo esincishisiwe: Ngobai-fiberglass rebar ungagqwali, ukushuba kwesembozo sikakhonkolo kungancishiswa kweminye imiklamo, kunciphise isisindo nezindleko zesakhiwo.
10. Ukusebenza kwesakhiwo okuthuthukisiwe: Kwezinye izinhlelo zokusebenza,i-fiberglass rebar ingasebenza kangcono ngokhonkolo futhi ithuthukise ukusebenza okuphelele kwesakhiwo, njengokugoba nokumelana nokugunda.
Naphezu kwalezi zinzuzo,i-fiberglass rebar nazo zinemikhawulo yazo, njengoba kushiwo ngaphambili. Ngakho-ke, lapho ukhetha ukusebenzisa ingilazi fiber ama-rebar, kuyadingeka ukucabangela ngokugcwele izidingo ezithile zesakhiwo kanye nezimo zemvelo.
