Ngokuthuthukiswa kobuchwepheshe bokukhiqiza izinto eziyinhlanganisela, kanye nokuqonda okujulile nokuqonda kwezinto eziyinhlanganisela embonini yezokuthutha ezihamba ngezitimela, kanye nenqubekelaphambili yezobuchwepheshe embonini yokukhiqiza izimoto ezihamba ngojantshi, ububanzi bokusetshenziswa kwezinto eziyinhlanganisela ezimotweni ezihamba ujantshi ziye zathuthuka. yandiswa kancane kancane.Izinhlobo, amamaki kanye namazinga obuchwepheshe wezinto eziyinhlanganisela ezisetshenziswayo nazo zithuthuka njalo.
Izinhlobo zezinto eziyinhlanganisela eziye zasetshenziswa ezimotweni ezihamba ngesitimela zihlanganisa:
(1) I-FRP ye-polyester engagcwalisiwe engaqinile futhi engaqinile;
(2) Ipulasitiki ene-phenolic resin glass fiber;
(3) I-FRP ye-polyester engagcwalisiwe ene-retardant ye-retardant enamandla amakhulu;
(4) Ipulasitiki eqinisiwe ye-polyester resin engagcwalisiwe yelangabi enamandla aphansi kancane;
(5) I-Carbon fiber material.
Kusuka kumaphuzu womkhiqizo kukhona:
(1) Izingxenye ze-FRP zokubeka isandla;
(2) Izingxenye ze-FRP ezibunjiwe;
(3) izingxenye ze-FRP zesakhiwo sesemishi;
(4) Izingxenye ze-carbon fibre.
Ukusetshenziswa kwe-FRP ku-Rail Transit Vehicles
1. Ukusetshenziswa kusenesikhathi kwe-FRP ezimotweni ezihamba ngesitimela
Ukusetshenziswa kwe-FRP ezimotweni ezihamba ngojantshi kwaqala ngeminyaka yawo-1980, futhi yaqala ukusetshenziswa ezitimeleni zikagesi ezihamba ngesivinini esiphansi ezikhiqizwa kuleli eziyi-140km/h.Ububanzi besicelo ikakhulukazi buhlanganisa:
● iphaneli yodonga lwangaphakathi;
● ipuleti eliphezulu elingaphakathi;
● Ithoyilethi lepulasitiki eliqiniswe ngengilazi elinefiber;
Inhloso enkulu yesicelo ngaleso sikhathi kwakunguKatsukiyogi.Uhlobo lwe-FRP olusetshenzisiwe yi-polyester resin engagcwalisiwe ye-FRP.
2. Ukusetshenziswa kweqoqo le-FRP ezimotweni zokuthutha umphakathi
Ukusetshenziswa kweqoqo le-FRP ezimotweni ezihamba ujantshi kanye nokuvuthwa kwayo kancane kancane kwenzeka ngeminyaka yawo-1990.Isetshenziselwa ikakhulukazi ukwakhiwa kwezimoto zabagibeli bezitimela kanye nezimoto zikaloliwe zasemadolobheni:
Iphaneli yodonga lwangaphakathi lwegumbi lezivakashi;
● Ipuleti eliphezulu langaphakathi;
I-glass fiber ehlanganisiwe yangasese yangasese yepulasitiki;
Integral glass fibre kwagcizelela yokugezela plastic;
Igumbi lokugezela lepulasitiki eliqinisiwe lengilazi elihlanganisiwe;
I-FRP air-conditioning duct, ipayipi yokukhipha imfucuza;
● Isihlalo noma uhlaka lwesihlalo.
Ngalesi sikhathi, okuhlosiwe kwesicelo okuyinhloko kushintshile ekushintsheni ukhuni kuya ekuthuthukiseni izinga lezimoto;izinhlobo ze-FRP ezisetshenzisiwe ziseyi-unsaturated polyester resin FRP.
3. Eminyakeni yakamuva, ukusetshenziswa kwe-FRP ezimotweni zikaloliwe
Kusukela ekuqaleni kwaleli khulu leminyaka, i-FRP ibisetshenziswa kabanzi ezimotweni ezihamba ngojantshi.Ngaphezu kokusetshenziswa ekwenzeni imikhiqizo ehlukahlukene eshiwo ngenhla, ibuye isetshenziswe kabanzi ekwenzeni:
● Indwangu yophahla;
Ipayipi lomoya elisha ophahleni;
●Izingxenye ezihlukahlukene ezinobumo obuyinkimbinkimbi emotweni, kuhlanganise namaphaneli odonga agobile angaphakathi anezinhlangothi ezintathu namaphaneli ophahla olusemaceleni;amaphaneli ekhava ezinhlobonhlobo ezikhethekile;ingilazi fibre eqiniswe plastic honeycomb panel panel;izingxenye zokuhlobisa.
Umgomo oyinhloko wohlelo lwe-FRP kulesi sigaba ukwenza izingxenye ezinezidingo ezikhethekile zokusebenza noma izidingo eziyinkimbinkimbi zokumodela.Ngaphezu kwalokho, ukumelana nomlilo kwe-FRP okusetshenziswe kulesi sigaba nakho kuthuthukisiwe.I-resin ye-polyester engafakwanga unsaturated ne-additive resin isetshenziswe kabanzi, futhi ukusetshenziswa kwe-phenolic resin FRP kuye kwehla kancane kancane.
4. Ukusetshenziswa kwe-FRP ku-EMU enesivinini esikhulu
Ukusetshenziswa kwe-FRP kuma-EMU wesitimela esinesivinini esikhulu sekungene esigabeni sokuvuthwa ngempela.ngoba:
(1) I-FRP isetshenziswa ekwenzeni izingxenye ezinemisebenzi ekhethekile, ubujamo obuyinkimbinkimbi nezakhiwo, nokusebenza okuhle kakhulu okuphelele okungamelana nemithwalo emikhulu, efana ne-FRP ehlanganisa imingcele ehlanganisiwe, amamojula emishini yokuvula nokuvalwa, uphahla lwendwangu ye-aerodynamic, njll.
(2) Ipulasitiki eqinisiwe yengilazi eyenziwe ngengilazi (SMC) isetshenziswe kabanzi
Ukusetshenziswa kwepulasitiki ebunjiwe yengilazi eqinisiwe ukwenza amaphaneli odonga angaphakathi abagibeli be-EMU anesivinini esiphezulu ngamaqoqo kunezinzuzo ezilandelayo:
Ukunemba kobukhulu bezingxenye kuphezulu;
●Izinga lokukhiqiza kanye nebanga lomkhiqizo,
●Kuzuzwe ngesisindo esincane;
●Kufanele ubunjiniyela bokukhiqiza ngobuningi.
(3) Thuthukisa izinga le-FRP esetshenziswa kwezinye izingxenye
● Ingenziwa izingxenye ezinezinhlobonhlobo ezihlukahlukene njengoba kudingeka;
Izinga lokubukeka lingcono, futhi ukunemba nokunemba kwezingxenye kuphakeme;
● Umbala ongaphezulu nephethini kungalungiswa ngesikhathi esifanayo.
Ngalesi sikhathi, ukusetshenziswa kwe-FRP kuhlanganisa ukufezeka kwemisebenzi ekhethekile kanye nokwakheka, nemigomo yezinga eliphezulu njengokuthwala umthwalo othile nesisindo esincane.
