Iyini i-glass fiber reinforced plastic?
Amapulasitiki aqiniswe nge-fiber enziwe ngengilazi ayizinhlobonhlobo zezinto eziyinhlanganisela ezinezakhiwo ezahlukahlukene kanye nokusetshenziswa okubanzi.Kuyinto entsha esebenzayo eyenziwe nge-synthetic resin kanyeizinto ezihlanganisiwe ze-fiberglass ngenqubo eyinhlanganisela.
Izici ze-glass fiber reinforced plastics:
(1)Ukumelana nokugqwala okuhle: I-FRP iyinto enhle ekwazi ukumelana nokugqwala.Inokumelana okuhle nomkhathi;amanzi kanye nokugxila okujwayelekile kwe-asidi ne-alkali;usawoti, amafutha ahlukahlukene kanye nezincibilikisi, futhi iye yasetshenziswa kabanzi kumakhemikhali e-anti-corrosion.kuzo zonke izici.Ithatha indawo ye-carbon steel;insimbi engagqwali;ukhuni;izinsimbi ezingenayo insimbi nezinye izinto.
(2) Isisindo esilula namandla aphezulu: Ukuminyana okuhlobene kwe-FRP kuphakathi kuka-1.5 no-2.0, okuyi-1/4 kuya ku-1/5 kuphela yaleyo ye-carbon steel, kodwa amandla aqinile aseduze noma aphakeme nakakhulu kunalawo e-carbon. insimbi, namandla angafaniswa nensimbi ye-alloy yezinga eliphezulu., asetshenziswa kakhulu emkhathini;iziqukathi ezinengcindezi ephezulu neminye imikhiqizo edinga ukwehlisa isisindo sazo.
(3) Izakhiwo zikagesi ezinhle: I-FRP iyinto enhle kakhulu yokuvikela i-insulating, esetshenziselwa ukwenza ama-insulators, futhi isengakwazi ukugcina ukusebenza kahle kumafrikhwensi aphezulu.
(4) Ukusebenza kahle kokushisa: I-FRP ine-conductivity kagesi ephansi, i-1.25 ~ 1.67KJ ekamelweni lokushisa, kuphela i-1/100 ~ 1/1000 yensimbi iyinto enhle kakhulu yokufaka ukushisa okushisayo.Ilungele ukuvikela okushisayo kanye nokumelana ne-ablation ngaphansi kwezimo zokushisa eziphezulu zesikhashana.
(5) Ukusebenza okuhle kakhulu kwenqubo: inqubo yokubumba ingakhethwa ngokuya ngesimo somkhiqizo, futhi inqubo ilula futhi ingabunjwa ngesikhathi esisodwa.
(6) Ukuklama okuhle: izinto zokwakha zingakhethwa ngokugcwele ngokwezidingo ukuze kuhlangatshezwane nezidingo zokusebenza nokwakheka komkhiqizo.
(7) Imoduli enwebekayo ephansi: I-elastic modulus ye-FRP inkulu izikhathi ezingu-2 kunezokhuni kodwa izikhathi ezingu-10 ezincane kunezinsimbi, ngakho-ke kuvame ukuzwakala ukuthi ukuqina akwanele esakhiweni somkhiqizo futhi kukhubazeka kalula.Isixazululo singenziwa sibe isakhiwo segobolondo elincanyana;isakhiwo sesangweji singabuye senziwe ngendlela yezintambo eziphezulu ze-modulus noma izimbambo eziqinisayo.
(8) Ukumelana nezinga lokushisa okungalungile kwesikhathi eside: Ngokuvamile, i-FRP ayikwazi ukusetshenziswa isikhathi eside ekushiseni okuphezulu, futhi amandla e-FRP e-polyester resin yenjongo evamile azokwehla kakhulu uma ingaphezu kwama-degree angu-50.
(9) Isimo sokuguga: ngaphansi kwesenzo semisebe ye-ultraviolet;umoya, isihlabathi, imvula neqhwa;imidiya yamakhemikhali;ukucindezeleka komshini, njll., kulula ukubangela ukuwohloka kokusebenza.
(10) Amandla okugunda we-interlaminar aphansi: Amandla okugunda kwe-interlaminar athwalwa yinhlaka, ngakho aphansi.Ukunamathela kwe-interlayer kungathuthukiswa ngokukhetha inqubo, kusetshenziswa i-ejenti yokuhlanganisa, njll., futhi uzame ukugwema ukugunda kwe-interlayer phakathi nokwakhiwa komkhiqizo.
Izinzuzo zamapulasitiki aqiniswe nge-fiber fiber:
Izinga lokushisa elimelana nokushisa lamapulasitiki aqiniswe ngefayibha yengilazi liphakeme kakhulu kunalelo elingenawo umcu wengilazi, ikakhulukazi amapulasitiki enayiloni.
Amapulasitiki aqiniswe ngefayibha yengilazi anokuncipha okuphansi nokuqina okuphezulu.
I-fiber yengilazi eqinisiwe yepulasitiki ayicindezeli ukuqhekeka, kanye nokumelana nomthelela wefemoglas fibra de vidrio ipulasitiki ithuthuke kakhulu
Amandla amapulasitiki aqiniswe nge-fiber fiber aphakeme, njengalokhu: amandla aqinile, amandla acindezelayo, amandla okugoba, konke kuphakeme kakhulu.
Ngenxa yokwengezwa kwezinye izithasiselo,izicubu ze-fiberamapulasitiki aqinisiwe anciphise kakhulu ukusebenza kokushiswa kwamapulasitiki aqiniswe ngefayibha yengilazi, futhi izinto eziningi azikwazi ukuvutha, ngakho-ke kuyinto ebamba ilangabi.
Ububi be-glass fiber reinforced plastics:
Ngenxa yokwengezwa kwee glassfiber, ipulasitiki eqiniswe ngefayibha yengilazi isiyi-opaque, futhi ibonakala ngale ngaphambi kokwengeza i-glass fiber.
Ipulasitiki yengilazi yengilazi eqinisiwe inokuqina okuphansi kanye nokuqina okukhulayo kunepulasitiki engenawo ingilazi yengilazi;
Ngenxa yokwengezwa kwe-fiber yengilazi, i-viscosity encibilikayo yazo zonke izinto iyakhula, i-fluidity iba mpofu, futhi ingcindezi yomjovo iphakeme kakhulu kunalokho ngaphandle kwe-glass fiber.Ekubumbeni okujwayelekile komjovo, izinga lokushisa lomjovo lawo wonke amapulasitiki aqinisiwe liphezulu kunalokho ngaphandle kokwengeza i-glass fiber.I-fiber yengilazi ngaphambilini yayiphakanyiswe ngu-10 ℃-30 ℃.
Ngenxa yokwengezwa kwe-glass fiber kanye nezithasiselo, izakhiwo ze-hygroscopic zei-fiberglass amapulasitiki aqinisiwe athuthukiswa kakhulu.Amapulasitiki ahlanzekile angawamunyi amanzi nawo azomunca.Ngakho-ke, kufanele zomiswe ngesikhathi sokubunjwa komjovo.
Ngesikhathi sokubumba umjovo wepulasitiki eqinisiwe ye-fiber fiber, i-fiber yengilazi ingangena ebusweni bomkhiqizo wepulasitiki, yenze ingaphezulu lomkhiqizo libe lukhuni kakhulu futhi linamabala.Ukuze kuzuzwe ikhwalithi ephezulu, umshini wokushisa wesikhunta usetshenziselwa ukushisa isikhunta ngesikhathi sokubunjwa komjovo, ukuze i-polymer yepulasitiki ingene ebusweni bomkhiqizo, kodwa ikhwalithi yokubukeka yepulasitiki ehlanzekile ayikwazi ukutholakala.
Ngemuva kokuthi i-fiber yengilazi iqinisiwe,e glass fiberglass iyimpahla enobulukhuni obuphakeme.Ngemuva kokuthi isithasiselo sivuthululwe ekushiseni okuphezulu, igesi egqwala kakhulu, ebangela ukuguga okukhulu nokugqwala kusikulufu nokubunjwa komjovo womshini wokubumba umjovo.Ngakho-ke, lolu hlobo lwezinto lusetshenziswa ekukhiqizeni.Lapho usebenzisa isikhunta nemishini yokubumba yomjovo, naka ukwelashwa okungaphezulu kokugqwala kanye nokwelashwa kokuqina kwendawo kwemishini.
Ukuqinisa umphumela we-glass fiber kunayiloni
Inayiloni, eyaziwa nangokuthi i-polyamide, iyimpahla yokwenziwa enezinhlobonhlobo zezicelo, esetshenziswa ezindwangu, emaphaketheni, ezingxenyeni zemishini nakweminye imikhakha.
Njengepulasitiki yobunjiniyela, i-PA66 iqukethe inqwaba yamaqembu e-hydrophilic amide, ebeka umkhawulo emkhakheni wesicelo sayo.Ivame ukusetshenziswa embonini ukuyishintsha ngokusebenzisa i-copolymerization, ukuhlanganisa ukuqina, nokuqinisa.
I-Glass fiber reinforcement iyindlela evame ukusetshenziswa yokuguqula.Ingathuthukisa ngempumelelo ukumelana nokugqokwa, amandla, ubulukhuni kanye nokuzinza kwe-nylon.
I-Glass fiber yenziwe nge-pyrophyllite, isihlabathi se-quartz, i-limestone namanye amaminerali ngokushisa okuphezulu kokushisa, ukudweba ucingo, ukugoqa, ukuluka nezinye izinqubo, futhi ububanzi bayo be-monofilament bumayelana nama-microns ambalwa.
Isimiso sokuqinisa i-fiber fiber: Kunezindlela ezintathu zokuthi ifayibha imunce amandla omthelela: ukuphuka kwefayibha, ukudonsa i-fiber, nokuphuka kwe-resin.Lapho ubude be-fiber bukhuphuka, i-fiber ekhiphayo idla amandla amaningi, okuyinzuzo ekuthuthukiseni amandla omthelela.
I-PA66/glass fiber composite material inokumunca amanzi aphansi, amandla athile aphezulu kanye nokumelana namakhemikhali, futhi imikhiqizo yayo inokumelana nokumuncwa komswakama okuhle, ukuzinza kwe-dimensional, amandla aphezulu, ubulukhuni, nokusebenza kokucubungula, ngakho isetshenziswa kabanzi kojantshi, imishini, izimoto. , izinto zikagesi kanye neminye imikhakha.
Ubude beingilazi ye-elastic modulus fiber glassngokuvamile esetshenziselwa ukuqinisa inayiloni cishe 3mm kuya 12mm.Njengoba ubude be-fiber bukhula, umphumela ekuqinisweni kwezinto ezibonakalayo uyakhula.Kuhle ku-12mm.
Ngokuvamile, ubude bei-fiberglass filamentingu-12mm, futhi ubude be-oqoshiwe ingilazi fiberngi 3mm.Uma kuqhathaniswa ne-fiber yengilazi emfushane, isici esiphawulekayo sokuqiniswa kwe-fiber yengilazi ende ukuthi amandla omthelela aphindwe kabili.Ngaphezu kwalokho, izinhlanganisela ze-nylon zengilazi ende eziqiniswe ngengilazi zinezinzuzo zamandla aphezulu, ukuqina okuphezulu, amandla omthelela aphezulu, ukumelana nokushisa kwesikhathi esifushane kanye nokumelana nokukhathala okuhle, futhi zingakwazi ukugcina izakhiwo ezinhle zemishini ekushiseni okuphezulu nasezindaweni ezinomswakama ophezulu., engasetshenziswa njengezinto zokwakha esikhundleni sensimbi.
