I-pultrusionizinto ezihlanganisiweziyizinhlanganisela ze-fiber-reinforced polymer (FRP) ezisebenza kahle kakhulu ezikhiqizwa kusetshenziswa inqubo eqhubekayo eyaziwa ngokuthi i-pultrusion.

Kule nqubo, imicu eqhubekayo (njengengilazi noma ikhabhoni) idonswa kubhavu we-thermosetting resin (njenge-epoxy resin, i-polyester, noma i-vinyl ester), bese kusetshenziswa isikhunta ukuze silolonge izinto ngendlela efunwa ngayo. I-resin ibe isilapha, yenze umkhiqizo oyinhlanganisela oqinile, ongasindi, futhi ohlala isikhathi eside.

I-pultrusionAma-resin 

I-matrix resin iyisici esibalulekile sezinto ezihlanganisiwe ze-pultrusion. Ama-resin ajwayelekile e-Pultrusion afaka i-epoxy, i-polyurethane, i-phenolic, i-vinyl ester, kanye nezinhlelo ezisanda kufundwa kabanzi ze-thermoplastic resin. Ngenxa yezici zezinto ezihlanganisiwe ze-pultrusion, i-matrix resin idinga ukuba ne-viscosity ephansi, amazinga okusabela okusheshayo emazingeni okushisa aphezulu. Lapho ukhetha i-matrix resin, izici ezifana ne-pultrusion reaction rate kanye ne-resin viscosity zidinga ukucatshangelwa. I-viscosity ephezulu ingathinta umphumela wokugcoba ngesikhathi sokukhiqiza umkhiqizo.

I-Epoxy Resin 

Izinto ezihlanganisiwe ze-pultrusion ezilungiselelwe nge-epoxy pultrusion resins zibonisa amandla aphezulu futhi zingasetshenziswa ngaphansi kwezimo ezishisa kakhulu, ngokwelashwa okusheshayo.

isivinini. Kodwa-ke, izinselele ezinjengokuqina kwempahla, isikhathi esifushane sokusebenza, ukungangeneli kahle, kanye nezinga lokushisa eliphezulu lokuphulukisa linciphisa ukuthuthukiswa kwemboni yamandla omoya e-China, ikakhulukazi ku-wind turbine blade nezinto zezimpande.

I-polyurethane 

I-polyurethane resin ine-viscosity ephansi, evumela okuqukethwe kwe-fiber yengilazi ephakeme uma kuqhathaniswa ne-polyester noma i-vinyl ester resins. Lokhu kubangela izinto eziyinhlanganisela ye-pultrusion polyurethane ene-modulus egobayo yokunwebeka eduze naleyo ye-aluminium. I-polyurethane ibonisa ukusebenza okuhle kakhulu kokucubungula uma kuqhathaniswa namanye ama-resin.

I-Phenolic Resin 

Eminyakeni yamuva nje, izinto ezihlanganisiwe ze-pultrusion ezisebenzisa i-phenolic resin ziye zathola ukunakwa ngenxa yobuthi bazo obuncane, ukukhishwa kwentuthu ephansi, ukumelana nelangabi, futhi zithole ukusetshenziswa ezindaweni ezifana nezokuthutha ngololiwe, amapulatifomu okumba uwoyela aphesheya kwezilwandle, izindawo zokusebenzela ezimelana nokubola kwamakhemikhali, kanye namapayipi. . Kodwa-ke, ukusabela okungokwesiko kwe-phenolic resin zokwelapha kuhamba kancane, okuholela emijikelezweni yokubumba emide, nokwakheka kwamabhamuza ngesikhathi sokukhiqiza okuqhubekayo okusheshayo, okuthinta ukusebenza komkhiqizo. Amasistimu we-Acid catalysis ngokuvamile asetshenziselwa ukunqoba lezi zinselele.

I-Vinyl Ester Resin 

I-Vinyl ester alcohol resin inezici ezinhle kakhulu zomshini, ukumelana nokushisa, ukumelana nokugqwala, kanye nokwelapha ngokushesha. Ngonyaka ka-2000, kwakungenye yezinhlaka ezithandwayo zemikhiqizo ye-pultrusion.

I-Thermoplastic Resin 

Izinhlanganisela ze-Thermoplastic zinqoba izithiyo zemvelo zezinhlanganisela ze-thermosetting, zinikeza ukuguquguquka okuqinile, ukumelana nomthelela, ukubekezelela okuhle komonakalo, kanye nezakhiwo zokudambisa. Zimelana nokugqwala kwamakhemikhali nemvelo, zinenqubo yokwelapha ngokushesha ngaphandle kokusabela kwamakhemikhali, futhi zingasetshenzwa ngokushesha. Izinsalela ze-thermoplastic ezivamile zihlanganisa i-polypropylene, inayiloni, i-polysulfide, i-polyether ether ketone, i-polyethylene, ne-polyamide.

Uma kuqhathaniswa nezinto zendabuko ezifana nensimbi, i-ceramics, namapulasitiki angaqinisiwe, izinhlanganisela ze-glass fibre-reinforced pultrusion composites zinezinzuzo ezimbalwa. Banekhono eliyingqayizivele lokuklama ngokwezifiso ukuze bahlangabezane nezidingo ezithile zomkhiqizo.

Izinzuzo zeI-pultrusionIzinto Ezihlanganisiwe:

I-1.Impumelelo Yokukhiqiza: Ukubumba kwe-Pultrusion kuyinqubo eqhubekayo enezinzuzo ezifana nevolumu yokukhiqiza ephezulu, izindleko eziphansi, nezikhathi zokulethwa okusheshayo uma kuqhathaniswa nezinye izindlela zokukhiqiza eziyinhlanganisela.

I-2.High Strength-to-Weight Ratio: Izinto eziyinhlanganisela ye-Pultrusion ziqinile futhi ziqinile kodwa azisindi. I-Carbon fiber pultrusions ilula kakhulu kunezinsimbi nezinye izinto, izenza zifanelekele ukusetshenziswa okuzwela isisindo ku-aerospace, izimoto, nezokuthutha.

I-3.I-Corrosion Resistance: Izinhlanganisela ze-FRP zibonisa ukumelana nokugqwala okuqinile, okuzenza zilungele ukusetshenziswa ezimbonini ezifana nokucubungula amakhemikhali, olwandle, uphethiloli, negesi yemvelo.

I-4.I-Insulation kagesi: I-Glass fibre pultrusions ingaklanywa ukuthi ingabi ne-conductive, iyenze ibe yisinqumo esihle sezinhlelo zokusebenza zikagesi ezidinga ukusebenza kwe-dielectric.
Ukuzinza Kwe-Dimensional: Izinto ezihlanganisiwe ze-Pultrusion aziwohloki noma aziqhekeki ngokuhamba kwesikhathi, okubalulekile ezinhlelweni zokusebenza ezinokubekezelelana okunembile.

I-5.I-Custom Design: Izingxenye ze-pultrusion zingenziwa ngezindlela ezihlukahlukene nobukhulu, kufaka phakathi izinduku, amashubhu, imishayo, namaphrofayili ayinkimbinkimbi. Zenziwa ngendlela oyifisayo kakhulu, okuvumela ukuhlukahluka komklamo ohlotsheni lwefayibha, umthamo wefayibha, uhlobo lweresin, iveli elingaphezulu, kanye nokwelashwa ukuze kuhlangatshezwane nezidingo ezithile zokusebenza nezinhlelo zokusebenza.

Ububi bokusebenzisapultrusionIzinto Ezihlanganisiwe:

1.Izimo Zejiyomethri Ezilinganiselwe: Izinto ezihlanganisiwe ze-pultrusion zikhawulelwe ezingxenyeni ezineziphambano ezihlala njalo noma ezicishe zibe njalo ngenxa yenqubo yokukhiqiza eqhubekayo lapho izinto eziqiniswe nge-fiber zidonswa ngesikhunta.

I-2.Izindleko Eziphezulu Zokukhiqiza: Isikhunta esisetshenziswa ekubumbeni i-pultrusion singabiza. Kudingeka zenziwe ngezinto ezisezingeni eliphezulu ezikwazi ukumelana nokushisa nokucindezela kwenqubo ye-pultrusion, futhi kufanele zikhiqizwe ngokubekezelela okuqinile kwemishini.

I-3.Amandla Aguquguqukayo Aphansi: Amandla aguquguqukayo wezinto ezihlanganisiwe ze-pultrusion aphansi kunamandla we-longitudinal, okwenza abe buthaka ekuqondeni kwe-perpendicular to the fibers. Lokhu kungaxazululwa ngokuhlanganisa izindwangu eziningi ze-axial noma imicu ngesikhathi senqubo ye-pultrusion.

4.Ukulungisa Okunzima: Uma izinto eziyinhlanganisela ye-Pultrusion zonakele, ukuzilungisa kungaba inselele. Zonke izingxenye zingadinga ukushintshwa, okungabiza futhi kudle isikhathi.

Izicelo zeI-pultrusionIzinto EzihlanganisiwepultrusionIzinto ezihlanganisiwe zithola ukusetshenziswa okugcwele ezimbonini ezahlukahlukene, kufaka phakathi:

1.I-Aerospace: Izingxenye zezindiza nemikhumbi-mkhathi, njengendawo yokulawula, igiya lokuhlala, nezisekelo zesakhiwo.

2.Ezezimoto: Izingxenye zezimoto, okuhlanganisa ama-drive shaft, obhampa, nezinto ezimisiwe.

3.Ingqalasizinda: Ukuqinisa kanye nezingxenye zengqalasizinda, njengezindawo zokulala, izitezi zamabhuloho, ukulungiswa nokuqinisa ukhonkolo, izigxobo zezinsiza, izivikeli zikagesi, nezikhali eziwelayo.

I-4.Ukucutshungulwa Kwamakhemikhali: Imishini yokucubungula amakhemikhali njengamapayipi ne-gratings yaphansi.

Ezokwelapha: Ukuqiniswa kwama-brace nama-endoscopic probe shafts.

5.Olwandle: Izinhlelo zokusebenza zasolwandle, okuhlanganisa izinsika, ama-battens, ama-dock pilings, izikhonkwane zehange, namadokhi.

6.Uwoyela Negesi: Ukufakwa kukawoyela negesi, okuhlanganisa izihloko zemithombo, amapayipi, izinti zokumpompa, nezinkundla.

7.Amandla omoya: Izingxenye zama-wind turbine blade, njengeziqinisi ze-blade, ama-spar caps, neziqinisekiso zezimpande.

8.Izisetshenziswa Zezemidlalo: Izingxenye ezidinga ukuphambana okungaguquki, okufana nokushushuluza, izigxobo zokushushuluza, okokusebenza kwegalofu, izigwedlo, izingxenye zokucibishela, nezigxobo zamatende.

Uma kuqhathaniswa nezinsimbi zendabuko namapulasitiki, izinto ezihlanganisiwe zePultrusion zinikeza izinzuzo eziningi. Uma ungunjiniyela wezinto zokwakha ofuna izinto zokwakha ezisebenza kahle kakhulu zohlelo lwakho lokusebenza, izinto ezihlanganisiwe zePultrusion ziyinketho esebenzayo.
