Izinto eziqinisayo ziwuhlaka lwamathambo asekelayoFRP umkhiqizo , okunquma ngokuyisisekelo izici zemishini zomkhiqizo owenziwe i-pultruded. Ukusetshenziswa kwezinto eziqinisayo nakho kunomphumela othile ekunciphiseni ukushwabana komkhiqizo kanye nokwandisa izinga lokushisa lokuguquguquka okushisayo kanye namandla omthelela okushisa aphansi.
Ekwakhiweni kwemikhiqizo ye-FRP, ukukhethwa kwezinto eziqinisayo kufanele kucabangele ngokugcwele inqubo yokubumba yomkhiqizo, ngoba uhlobo, indlela yokubeka kanye nokuqukethwe kwezinto eziqinisayo kunethonya elikhulu ekusebenzeni kwemikhiqizo ye-FRP, futhi ngokuyisisekelo inquma umshini. amandla kanye ne-elastic modulus yemikhiqizo ye-FRP. Ukusebenza kwemikhiqizo ye-pultruded usebenzisa izinto zokuqinisa ezihlukene nakho kuhlukile.
Ngaphezu kwalokho, ngenkathi uhlangabezana nezidingo zokusebenza komkhiqizo wenqubo yokubumba, izindleko kufanele zicatshangelwe, futhi izinto zokuqinisa ezishibhile kufanele zikhethwe ngangokunokwenzeka. Ngokuvamile, ukuzungeza okungasontiwe kwemicu ye-fiber yengilazi kunezindleko eziphansi kunezindwangu zefayibha; izindleko zokuzizwa ziphansi kunezendwangu, futhi ukungagxili 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 zizokwehla.
Izinhlobo zezinto ezivame ukusetshenziswa eziqinisayo zimi kanje:
1. I-Glass Fiber Roving Engasontekile
Kusetshenziswa i-ejenti yokulinganisa eqinisiwe, i-fiber roving yengilazi engasontekile ingahlukaniswa ngezinhlobo ezintathu: umucu oyiplied, i-roving eqondile engasontekile kanye ne-bulked untwisted roving.
Ngenxa yokungezwani okungalingani kwezintambo ezinamaplied, kulula ukugoqa, okwenza iluphu exekethile ekugcineni kokuphakela kwemishini ye-pultrusion, ethinta inqubekelaphambili yomsebenzi.
Ukuzungeza okungasontekile okuqondile kunezici zokunqwabelana okuhle, ukungena kwe-resin okusheshayo, kanye nezakhiwo ezinhle kakhulu zemishini yemikhiqizo, ngakho-ke iningi lazo livame ukusebenzisa ama-roving angasontekile okwamanje.
Ukuzulazula ngenqwaba kuyazuzisa ukuthuthukisa amandla aguquguqukayo emikhiqizo, njengokuzulazula okubomvana kanye nokuzulazula okunokwakheka komoya. I-Bulk roving inakho kokubili amandla aphezulu emicu emide eqhubekayo kanye nobukhulu bemicu emifushane. Kuyimpahla enokumelana nokushisa okuphezulu, ukuguquguquka okuphansi kwe-thermal, ukumelana nokugqwala, umthamo omkhulu kanye nokusebenza kahle kokuhlunga okuphezulu. Eminye imicu inqwabelana ibe yisimo se-monofilament, ngakho-ke ingabuye ithuthukise ikhwalithi ephezulu yemikhiqizo ye-pultruded. Njengamanje, ama-roving amaningi asesetshenziswe kakhulu ekhaya naphesheya, njengezintambo eziqondile nezilukiweyo zendwangu yokuhlobisa noma yezimboni. Ingasetshenziselwa ukukhiqiza ukungqubuzana, ukwahlukanisa, ukuvikela noma izinto zokuvala uphawu.
Izidingo zokusebenza ze-glass fibre roving for pultrusion:
(1) Ayikho i-drape phenomenon
(2) Ukuqina kwe-fiber okufanayo
(3) Ukuhlanganisa okuhle
(4) Ukumelana nokugqoka okuhle
(5) Ephukile Amakhanda ambalwa, akulula ukuwapheka
(6) Ukumanzisa okuhle kanye nokufakwa kwe-resin okusheshayo
(7) Amandla aphezulu kanye nokuqina.
2. I-Fiberglass Mat
Ukuze wenze imikhiqizo ye-FRP ecijile ibe namandla anele aguquguqukayo, kuyadingeka ukusebenzisa izinto eziqinisayo ezifana ne-strand mat eqoshiwe, umata we-strand oqhubekayo, umata ohlangene, nendwangu ezulayo. I-Continuous strand mat ingenye yezinto ezivame ukusetshenziswa kakhulu zengilazi ze-fiber transverse reinforcement njengamanje. Ukuze kuthuthukiswe ukubukeka kwemikhiqizo, kwesinye isikhathi kusetshenziswa i-surface mat.
I-strand mat eqhubekayo yakhiwe izingqimba eziningana zemicu yengilazi eqhubekayo ebekwe ngokungahleliwe kuyindilinga, futhi imicu iboshwe nge-adhesive. I-surface mat iyithishu encane efana nephepha eyakhiwe ngokubeka ngokungahleliwe nangokulinganayo imicu eqoshiwe yobude obugxilile futhi iboshwe nge-adhesive. Okuqukethwe kwe-fiber kungu-5% kuya ku-15%, futhi ukujiya kungu-0.3 kuya ku-0.4 mm. Ingenza ubuso bomkhiqizo bushelelezi futhi bube buhle, futhi ithuthukise ukumelana nokuguga komkhiqizo.
Izici ze-glass fiber mat yilezi: ukumboza okuhle, ukugcwala kalula nge-resin, nokuqukethwe kweglue ephezulu.
Izidingo zenqubo ye-pultrusion ye-glass fiber mat:
(1) Inamandla amakhulu emishini
(2) Komata bemicu abaqoshwe ngamakhemikhali, isibophezelo kumele simelane nemiphumela yamakhemikhali neyokushisa ngesikhathi sokucwiliswa kanye nokwenza kabusha ukuze kuqinisekiswe amandla anele ngesikhathi sokubunjwa.
(3) Ukumanzisa okuhle
(4) I-fluff encane futhi amalunga/iziphetho ezimbalwa eziphukile
3.I-polyesterFiberSubusoIzicubu
I-polyester fiber surface tissue wuhlobo olusha lwe-fiber material eqinisayo embonini ye-pultrusion. Kukhona umkhiqizo obizwa nge-Nexus e-United States, osetshenziswa kakhulu emikhiqizweni ephuhliwe ukuze umiselele omati/izicubu/uboya be-glass fibre surface. Inomphumela omuhle kanye nezindleko eziphansi. Isetshenziswe ngempumelelo iminyaka engaphezu kwe-10.
Izinzuzo zokusebenzisa i-polyester fiber surface tissue:
(1) Ingathuthukisa ukumelana nomthelela, ukumelana nokugqwala kanye nokumelana nokuguga komkhathi komkhiqizo
(2) Ingathuthukisa isimo somkhiqizo futhi yenze ingaphezulu lomkhiqizo libe bushelelezi
(3) I-polyester fiber surface tissue, ukusebenza okunamathelayo nokusebenza okuqinile kungcono kakhulu kune-C glass surface tissue/mat, futhi akulula ukunqamula iziphetho ngesikhathi senqubo ye-pultrusion, kunciphisa izingozi zokupaka.
(4) Ingathuthukisa isivinini se-pultrusion
(5) Kunganciphisa ukuguga kwesikhunta futhi kuthuthukise impilo yesevisi yesikhunta.
4. IngilaziClothi/Tinkawu
Kweminye imikhiqizo ekhethekile ene-pultruded, ukuze kuhlangatshezwane nezidingo ezithile zokusebenza ezikhethekile, kusetshenziswa indwangu yengilazi enobubanzi obungaguquki kanye nogqinsi olungaphansi kuka-0.2mm, futhi amandla ayo aqinile namandla aguquguqukayo kuhle kakhulu.
5. Ukusetshenziswa kweTi-wo-dimensionalFamajazi& Ezintathu-enobukhuluFamajazi
Izakhiwo eziphambanayo zemishini yemikhiqizo ehlanganisiwe eyinhlanganisela zimbi. Ukusetshenziswa kwe-braiding yezindlela ezimbili kuthuthukisa ngempumelelo amandla nokuqina kwemikhiqizo e-pultruded.
Imicu egobile neyi-weft yale ndwangu elukiwe ayihlangene, kodwa ihlanganiswe nenye into elukiweyo, ngakho ihluke ngokuphelele kwendwangu yengilazi evamile. Amafayibha ohlangothini ngalunye asesimweni sokungqubuzana futhi awakhi Noma yikuphi ukugoba, futhi ngaleyo ndlela amandla nokuqina komkhiqizo we-pultruded, kuphakeme kakhulu kunaleyo yenhlanganisela eyenziwe ngomuzwa oqhubekayo. Njengamanje, ubuchwepheshe bokuluka bezindlela ezintathu buye baba inkambu ekhangayo futhi esebenzayo yokuthuthukiswa kobuchwepheshe embonini yezinto eziyinhlanganisela. Ngokwezidingo zomthwalo, i-fibre yokuqinisa ilukwa ngokuqondile ibe yisakhiwo esinezinhlangothi ezintathu, futhi ukwakheka kuyafana nokuma komkhiqizo oyinhlanganisela owakhayo. Indwangu yezindlela ezintathu esetshenziselwa inqubo ye-pultrusion inganqoba i-interlaminar shear yemikhiqizo yendabuko yokuqinisa i-fiber pultrusion. Inobubi bamandla e-shear aphansi kanye ne-delamination elula, futhi ukusebenza kwayo kwe-interlayer kuhle kakhulu. (Umthombo: I-Fiberglass Composites / Composites Community)
