Izinto eziqinisayo uhlaka lwamathambo olusekelayo lomkhiqizo we-FRP, olunquma ngokuyisisekelo izici zomshini womkhiqizo ophuhliwe. Ukusetshenziswa kwezinto eziqinisayo nakho kunomphumela othile ekunciphiseni ukushwabana komkhiqizo nokwandisa izinga lokushisa lokushintsha okushisayo 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, ukuzulazula okungakhethi kwemicu ye-fiber yengilazi kunezindleko eziphansi kunezindwangu zefayibha; izindleko zeingilazi fiber mataiphansi kunaleyo yendwangu, futhi ukungagxili kuhle. , kodwa amandla mancane; 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. Ukuzulazula kwe-fiber yengilazi engasontekile
Kusetshenziswa i-ejenti yokulinganisa eqinisiwe, engasontiweingilazi fiber rovingzingahlukaniswa zibe izinhlobo ezintathu: plied usilika eluhlaza, roving ngqo untwisted kanye bulked untwisted untwisted.
Ngenxa yokungezwani okungalingani kwezintambo ezinamaphiko, kulula ukugoqa, okwenza iluphu exegayo ekugcineni kwesiphakeli semishini ye-pultrusion, ethinta ukuqhubeka kahle komsebenzi.
Ukuzulazula okungasontekile okuqondile kunezici zokunqwabelana okuhle, ukungena kwe-resin okusheshayo, kanye nezakhiwo ezinhle kakhulu zemishini yemikhiqizo, ngakho-ke iningi lama-roving angasontekile avame ukusetshenziswa njengamanje.
Ama-rovings anenqwaba anenzuzo ekuthuthukiseni amandla aguquguqukayo emikhiqizo, njengama-rovings ama-crimped kanye nama-rovings ane-air-textured. I-Bulk roving inakho kokubili amandla aphezulu emicu emide eqhubekayo kanye nobukhulu bemicu emifushane. Kuyimpahla enokumelana nokushisa okuphezulu, ukuguquguquka okuphansi kokushisa, 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-rovings amaningi asesetshenziswe kabanzi ekhaya naphesheya, njengezintambo eziqondile nezilukiweyo zendwangu yokuhlobisa noma yezimboni. Ingasetshenziselwa ukukhiqiza ukungqubuzana, ukwahlukanisa, ukuvikela noma izinto zokuvala.
Izidingo zokusebenza ze-glass fibre rovings ezingasontekile ze-pultrusion:
(1) Akukho mkhuba we-overhang;
(2) I-fiber tension ifana;
(3) Ukuhlanganisa okuhle;
(4) Ukumelana nokugqoka okuhle;
(5) Kunamakhanda ambalwa aphukile, futhi akulula ukuphaphatheka;
(6) Ukumanzisa okuhle kanye nokufakwa kwe-resin okusheshayo;
(7) Amandla aphezulu kanye nokuqina.
2. I-fiber mat yengilazi
Ukuze wenze imikhiqizo ye-FRP ecijile ibe namandla anele aguquguqukayo, izinto eziqinisayo ezifana ne-strand mat eqoshiwe, umata we-strand oqhubekayo, umata ohlangene, nendwangu yentambo engasontiwe kufanele isetshenziswe. I-Continuous strand mat ingenye yezinto ezivame ukusetshenziswa kakhulu zokuqinisa ingilazi ye-glass fibre transverse. Ukuze uthuthukise ukubukeka kwemikhiqizo,umata ongaphezulukwesinye isikhathi iyasetshenziswa.
I-strand mat eqhubekayo yakhiwa izingqimba eziningana zemicu yengilazi eqhubekayo ebekwe ngokungahleliwe endingilizini, futhi imicu iboshwe nge-adhesives. Ingaphezulu elizwakala liyiphepha elincanyana elizwakalayo elakhiwe 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: ukumbozwa okuhle, kulula ukugcwaliswa nge-resin, okuqukethwe okuphezulu kweglue
Izidingo zenqubo ye-pultrusion ye-glass fiber mat:
(1) Inamandla amakhulu emishini
(2) Komata bemicu ababoshwe ngamakhemikhali, isibophezelo kumele simelane nemiphumela yamakhemikhali neyokushisa ngesikhathi sokucwiliswa kanye nokwenza kabusha ukuze kuqinisekiswe amandla anele ngesikhathi sokwenza;
(3) Ukumanzisa okuhle;
(4) Ukuphaphatheka okuncane namakhanda aphukile ambalwa.
I-Fiberglass Stutched mat
I-Glass fiber composite mat
3. I-polyester fiber surface mat
I-polyester fiber surface ezwakalayo iwuhlobo olusha lwe-fiber material eqinisayo embonini ye-pultrusion. Kunomkhiqizo obizwa nge-Nexus e-United States, osetshenziswa kakhulu emikhiqizweni ye-pultruded ukushintshwaingilazi fiber surface mata. Inomphumela omuhle kanye nezindleko eziphansi. Isetshenziswe ngempumelelo iminyaka engaphezu kwe-10.
Izinzuzo zokusebenzisa i-polyester fiber tissue mat:
(1) Ingathuthukisa ukumelana nomthelela, ukumelana nokugqwala kanye nokumelana nokuguga komkhathi kwemikhiqizo;
(2) Ingathuthukisa isimo somkhiqizo futhi yenze ingaphezulu lomkhiqizo libe bushelelezi;
(3) Ukusetshenziswa kanye nezindawo eziqinile ze-polyester fiber surface ezizwakalayo zingcono kakhulu kune-C glass surface ezwakalayo, futhi akulula ukunqamula iziphetho ngesikhathi senqubo ye-pultrusion, ukunciphisa izingozi zokupaka;
(4) Ijubane le-pultrusion lingakhuphuka;
(5) Kunganciphisa ukuguga kwesikhunta futhi kuthuthukise impilo yesevisi yesikhunta
4. Itheyiphu yendwangu ye-fiber yengilazi
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 kwezindwangu ezinezinhlangothi ezimbili kanye nezindwangu ezinezinhlangothi ezintathu
Izakhiwo eziphambanayo zemishini yemikhiqizo eyinhlanganisela ephuhliwe zimbi, futhi ukusetshenziswa kokuluka okuphindwe kabili kuthuthukisa ngempumelelo amandla nokuqina kwemikhiqizo ephuhliwe.
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 ezihlanganisiwe. Ngokwezidingo zomthwalo, i-fibre eqinisayo ilukwa ngokuqondile ibe yisakhiwo esinezinhlangothi ezintathu, futhi ukwakheka kuyafana nalokho komkhiqizo oyinhlanganisela owakhayo. Indwangu yezindlela ezintathu isetshenziswa enqubweni ye-pultrusion ukunqoba 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.
