Izinto zokuqinisa ziwumgogodla osekelayo womkhiqizo we-FRP, onquma ngokuyisisekelo izakhiwo zemishini zomkhiqizo oqhekekile. Ukusetshenziswa kwezinto zokuqinisa nakho kunomthelela othile ekunciphiseni ukuncishiswa komkhiqizo nokwandisa izinga lokushisa lokuguquguquka kokushisa kanye namandla omthelela ophansi wokushisa.
Ekuklanyweni kwemikhiqizo ye-FRP, ukukhethwa kwezinto zokuqinisa kufanele kucabangele ngokugcwele inqubo yokubumba yomkhiqizo, ngoba uhlobo, indlela yokubeka kanye nokuqukethwe kwezinto zokuqinisa kunethonya elikhulu ekusebenzeni kwemikhiqizo ye-FRP, futhi ngokuyisisekelo kunquma amandla omshini kanye ne-modulus yokunwebeka yemikhiqizo ye-FRP. Ukusebenza kwemikhiqizo ehlanganisiwe kusetshenziswa izinto zokuqinisa ezahlukene nakho kuhlukile.
Ngaphezu kwalokho, ngenkathi kuhlangatshezwana nezidingo zokusebenza komkhiqizo zenqubo yokubumba, izindleko kufanele futhi zicatshangelwe, futhi izinto zokuqinisa ezishibhile kufanele zikhethwe ngangokunokwenzeka. Ngokuvamile, ukuzulazula kwezintambo zefayibha yengilazi okungakhethi kuphansi ngezindleko kunezindwangu zefayibha; izindlekoomata befayibha yengilaziiphansi kuneyendwangu, futhi ukungangenwa kwamanzi kuhle. , kodwa amandla aphansi; i-alkali fiber ishibhile kune-alkali-free fiber, kodwa ngokwanda kokuqukethwe kwe-alkali, ukumelana kwayo ne-alkali, ukumelana nokugqwala, kanye nezakhiwo zikagesi kuzoncipha.
Izinhlobo zezinto zokuqinisa ezisetshenziswa kakhulu yilezi ezilandelayo
1. Ukuhambahamba ngefayibha yengilazi engasontiwe
Ukusebenzisa i-ejenti yokulinganisa eqinisiwe, engasontiweukuhambahamba ngefayibha yengilaziingahlukaniswa ngezinhlobo ezintathu: usilika ongahluziwe ohlotshisiwe, ukuzulazula okuqondile okungajiki kanye nokuzulazula okungajiki okubunjiwe.
Ngenxa yokucindezeleka okungalingani kwemicu ehlanganisiwe, kulula ukugoba, okwenza iluphu ekhululekile ekugcineni kokuphakelwa kwemishini yokudonsa, okuthinta inqubekela phambili ebushelelezi yokusebenza.
Ukuzulazula okuqondile okungasontekile kunezici zokuhlanganisa okuhle, ukungena kwe-resin okusheshayo, kanye nezakhiwo ezinhle kakhulu zemishini yemikhiqizo, ngakho-ke iningi lama-roving angasontekile aqondile livame ukusetshenziswa njengamanje.
Ukuzungeza okuhlanganisiwe kunenzuzo ekuthuthukiseni amandla ajikelezayo emikhiqizo, njengemizungezo egoqekile kanye nokuzungeza okunesimo somoya. Ukuzungeza okuhlanganisiwe kunamandla aphezulu emicu emide eqhubekayo kanye nobukhulu bemicu emifushane. Kuyizinto ezinokumelana nokushisa okuphezulu, ukuhanjiswa kokushisa okuphansi, ukumelana nokugqwala, amandla aphezulu kanye nokusebenza kahle kokuhlunga okuphezulu. Ezinye imicu zizungeza zibe yisimo se-monofilament, ngakho-ke kungathuthukisa nekhwalithi yobuso bemikhiqizo exubile. Njengamanje, ukuzungeza okuhlanganisiwe kusetshenziswe kabanzi ekhaya nakwamanye amazwe, njengezintambo ezigoqekile nezigoqekile zezindwangu ezihlotshisiwe noma zezimboni. Kungasetshenziswa ukukhiqiza ukungqubuzana, ukuvikela, ukuvikela noma izinto zokuvala.
Izidingo zokusebenza kwe-rovings ye-glass fiber engasontiwe yokudonsa amanzi:
(1) Akukho senzakalo esilengayo;
(2) Ukuqina kwefayibha kuyafana;
(3) Ukuhlanganisa okuhle;
(4) Ukumelana okuhle nokuguguleka;
(5) Zimbalwa izinhloko eziphukile, futhi akulula ukuzishintshashintsha;
(6) Ukumanzisa okuhle kanye nokufuthwa kwe-resin okusheshayo;
(7) Amandla aphezulu nokuqina.
Isifutho se-fiberglass sihambahamba phezulu
2. Umata wefayibha yengilazi
Ukuze imikhiqizo ye-FRP ene-pultruded ibe namandla anele okuwela, izinto zokuqinisa ezifana nomata we-strand oqoshiwe, umata we-strand oqhubekayo, umata ohlanganisiwe, kanye nendwangu yentambo engasontiwe kumele kusetshenziswe. Umata we-strand oqhubekayo ungenye yezinto zokuqinisa eziwela ingilazi ezisetshenziswa kakhulu njengamanje. Ukuze kuthuthukiswe ukubukeka kwemikhiqizo,umata ongaphezulungezinye izikhathi isetshenziswa.
Uhlaka lwezintambo oluqhubekayo lwakhiwe ngezingqimba eziningana zezintambo zengilazi eziqhubekayo ezibekwe ngokungahleliwe esindilinga, kanti lezo zintambo ziboshwe ngezinamathiselo. Indwangu engaphandle iwuhlobo olufana nephepha olubunjwe ngokubeka ngokungahleliwe nangokulinganayo imicu eqoshiwe yobude obungaguquki bese iboshwe nge-glue. Okuqukethwe kwe-fiber kungu-5% kuya ku-15%, kanti ubukhulu bungu-0.3 kuya ku-0.4 mm. Kungenza ubuso bomkhiqizo bube bushelelezi futhi bube buhle, futhi kuthuthukise ukumelana nokuguga komkhiqizo.
Izici zomathi we-glass fiber yilezi: ukumbozwa okuhle, kulula ukugcwala nge-resin, okuqukethwe okuphezulu kweglue
Izidingo zenqubo yokudonsa ingilazi yefayibha:
(1) Inamandla amakhulu okusebenza
(2) Kuma-strand mat aqoshiwe ahlanganiswe ngamakhemikhali, i-binder kumele imelane nemiphumela yamakhemikhali kanye nokushisa ngesikhathi sokucwilisa nokulungisa ukuze kuqinisekiswe amandla anele ngesikhathi senqubo yokwakha;
(3) Ukumanzisa okuhle;
(4) Ukungakhululeki kahle kanye namakhanda aphukile kancane.

3. Umata womphezulu wefayibha ye-polyester
I-felt ye-polyester surface fiber uhlobo olusha lwezinto zokuqinisa i-fiber embonini ye-pultrusion. Kukhona umkhiqizo obizwa ngokuthi i-Nexus e-United States, osetshenziswa kabanzi emikhiqizweni ye-pultruded ukuze ungene esikhundleni sawo.omata bomphezulu befayibha yengilazi. Inomthelela omuhle futhi ishibhile. Isetshenziswe ngempumelelo iminyaka engaphezu kwe-10.
Izinzuzo zokusebenzisa umata we-polyester fiber tissue:
(1) Kungathuthukisa ukumelana nomthelela, ukumelana nokugqwala kanye nokumelana nokuguga kwemikhiqizo emoyeni;
(2) Kungathuthukisa isimo somphezulu womkhiqizo futhi kwenze umphezulu womkhiqizo ube bushelelezi;
(3) Ukusetshenziswa kanye nezakhiwo zokuthamba ze-polyester fiber surface felt zingcono kakhulu kune-C glass surface felt, futhi akulula ukuphula iziphetho ngesikhathi senqubo ye-pultrusion, okunciphisa izingozi zokupaka;
(4) Ijubane lokudonsa umoya lingakhushulwa;
(5) Kunganciphisa ukuguguleka kwesikhunta futhi kuthuthukise impilo yesevisi yesikhunta
4. Itheyiphu yendwangu yefayibha yengilazi
Kweminye imikhiqizo ekhethekile exubile, ukuze kuhlangatshezwane nezidingo ezithile zokusebenza ezikhethekile, kusetshenziswa indwangu yengilazi enobubanzi obungaguquki kanye nobukhulu obungaphansi kuka-0.2mm, futhi amandla ayo okuthamba kanye namandla okugudluza kuhle kakhulu.
5. Ukusetshenziswa kwezindwangu ezinezinhlangothi ezimbili nezinezinhlangothi ezintathu
Izakhiwo zemishini eziphambene zemikhiqizo ehlanganisiwe ene-pultruded azinhle, futhi ukusetshenziswa kokulukwa okuqondiswayo kuthuthukisa ngempumelelo amandla nokuqina kwemikhiqizo ene-pultruded.
Imicu ye-warp kanye ne-weft yale ndwangu elukiwe ayihlangene, kodwa ihlangene nenye into elukiwe, ngakho-ke ihluke ngokuphelele endwangu yengilazi yendabuko. Imicu ehlangothini ngalunye isesimweni se-collimated futhi ayakhi Noma yikuphi ukugoba, ngakho-ke amandla nokuqina komkhiqizo oqhekekile, kuphakeme kakhulu kunokwenhlanganisela eyenziwe nge-felt eqhubekayo.
Njengamanje, ubuchwepheshe bokulukwa obunezindlela ezintathu sebube yinkambu yokuthuthukiswa kobuchwepheshe ekhangayo nesebenzayo kakhulu embonini yezinto ezihlanganisiwe. Ngokwezidingo zomthwalo, i-fibre yokuqinisa ilukwa ngqo esakhiweni esinesakhiwo esinezilinganiso ezintathu, futhi ukuma kwayo kufana nomkhiqizo ohlanganisiwe owakhayo. Indwangu enezindlela ezintathu isetshenziswa enqubweni ye-pultrusion ukunqoba i-interlaminar shear yemikhiqizo yendabuko ye-fibre yokuqinisa. Inezinkinga zamandla aphansi okusika kanye nokuhlukanisa okulula, futhi ukusebenza kwayo kwe-interlayer kuhle kakhulu.
