Nekuvandudzwa kweiyo composite yekugadzira zvinhu tekinoroji, pamwe nekudzika kwekunzwisisa uye kunzwisisa kwezvinhu zvakaumbwa muindasitiri yezvitima, pamwe nekufambira mberi kwetekinoroji yeindasitiri yekugadzira mota dzenjanji, chiyero chekushandiswa kwezvinhu zvinoumbwa mumotokari dzenjanji chavepo. yakawedzera zvishoma nezvishoma.Mhando, mamakisi uye tekinoroji mazinga ezvakasanganiswa zvinhu zvinoshandiswa zvinogara zvichivandudza.
Mhando dzezvinhu zvakaumbwa zvakashandiswa mumotokari dzenjanji dzinosanganisira:
(1) Rigid uye semi-yakaomesesa unsaturated polyester resin FRP;
(2) Phenolic resin girazi fiber yakasimbiswa plastiki;
(3) Reactive flame retardant unsaturated polyester resin FRP ine simba guru;
(4) Additive flame retardant unsaturated polyester resin girazi fiber yakasimbiswa plastiki ine simba shoma shoma;
(5) Carbon fiber zvinhu.
Kubva pane zvigadzirwa mapoinzi ndeaya:
(1) Ruoko kuisa-up zvikamu zveFRP;
(2) Molded FRP zvikamu;
(3) FRP zvikamu zve sandwich chimiro;
(4) Carbon fiber zvikamu.
Kushandiswa kweFRP muRail Transit Vehicles
1. Kutanga kushandiswa kweFRP mumotokari dzenjanji
Kushandiswa kweFRP mumotokari dzenjanji kwakatanga muna 1980s, uye yakatanga kushandiswa mudzimba dzakagadzirwa 140km/h zvitima zvemagetsi zvakaderera.Kuwanda kwekushandisa kunonyanya kusanganisira:
● mukati memadziro emadziro;
● ndiro yepamusoro yemukati;
● Yakaungana girazi fiber yakasimbiswa chimbuzi chepurasitiki;
Chinangwa chikuru chekunyorera panguva iyoyo chaive Katsukiyogi.Mhando yeFRP inoshandiswa inonzi unsaturated polyester resin FRP.
2. Batch application yeFRP pamotokari dzenjanji
Iyo batch application yeFRP pamotokari dzenjanji uye kukura kwayo zvishoma nezvishoma kwakaitika muma1990.Inonyanya kushandiswa kugadzira njanji yevafambi mota uye mota dzemudhorobha njanji:
Rusvingo rwemukati rweimba yevaenzi;
● Inner top plate;
Yakaungana girazi fiber yakasimbiswa chimbuzi chepurasitiki;
Integral girazi faibha yakasimbiswa epurasitiki yekugezera;
Integral girazi faibha yakasimbiswa epurasitiki washroom;
FRP air-conditioning duct, tsvina inopedza tsvina;
● Furemu yechigaro kana chigaro.
Panguva ino, chinangwa chikuru chekushandisa chakachinja kubva pakutsiva huni kusvika pakuvandudza giredhi remotokari;iwo marudzi eFRP anoshandiswa achiri kunyanya unsaturated polyester resin FRP.
3. Mumakore achangopfuura, kushandiswa kweFRP mumotokari dzenjanji
Kubva pakutanga kwezana rino remakore, FRP yakashandiswa zvakanyanya mumotokari dzenjanji.Pamusoro pekushandiswa mukugadzirwa kwezvinhu zvakasiyana-siyana zvataurwa, zvakare inoshandiswa zvakanyanya mukugadzira:
●Chifukidzo chedenga;
Mutsva wemhepo padenga;
● Zvimiro zvakasiyana-siyana zvine zvimiro zvakaoma mumotokari, zvinosanganisira matatu-dimensional akakomberedzwa mukati memadziro emadziro uye mativi edenga mapaneru;kuvhara mapepa emhando dzakasiyana-siyana dzakakosha;girazi faibha yakasimbisa epurasitiki huchi madziro mapaneru;zvekushongedza zvikamu.
Chinangwa chikuru cheFRP application pane ino nhanho kugadzira zvikamu zvine zvakakosha zvinoshanda zvinodiwa kana yakaoma modhi zvinodiwa.Mukuwedzera, kupikisa kwemoto kweFRP kunoshandiswa muchikamu ichi kwakagadziridzwa zvakare.Reactive uye additive flame retardant unsaturated polyester resin FRP yakashandiswa zvakanyanya, uye kushandiswa kwephenolic resin FRP kwakadzikira zvishoma nezvishoma.
4. Kushandiswa kweFRP muEMU yepamusoro-soro
Iko kushandiswa kweFRP mune yakakwira-kumhanya njanji EMUs kwanyatsopinda mudanho rekukura.nokuti:
(1) FRP inoshandiswa mukugadzirwa kwezvikamu zvine mabasa akakosha, maumbirwo akaomarara uye zvimiro, uye yakanakisa mashandiro akazara ayo anogona kumira mitoro mikuru, senge FRP inosanganisirwa streamlined fronts, kumberi-kumagumo kuvhura uye kuvhara mamodules, padenga aerodynamic shrouds, nezvimwewo.
(2) Molded glass fiber reinforced plastic (SMC) yakashandiswa zvakanyanya
Iko kushandiswa kwegirazi yakaumbwa fiber yakasimbiswa epurasitiki kugadzira yakakwirira-yekukurumidza EMU mufambi wemukati madziro mapaneru mumabhechi ane zvinotevera zvakanakira:
Kurongeka kwedimensional yezvikamu zvakakwirira;
●Kugadzira mhando uye giredhi yechigadzirwa,
● Akawana huremu;
●Inokodzera engineering yakawanda kugadzirwa.
(3) Kuvandudza huwandu hweFRP inoshandiswa mune zvimwe zvikamu
● Inogona kugadzirwa muzvikamu zvine mavara akasiyana-siyana sezvinodiwa;
Unhu hwekutaridzika huri nani, uye chimiro uye chiyero chechokwadi chezvikamu zvakakwirira;
● Muvara wepamusoro uye pateni zvinogona kugadziriswa panguva imwe chete.
Panguva ino, kushandiswa kweFRP kunosanganisira kuzadzikiswa kweakakosha mabasa uye maumbirwo, uye nepamusoro-nhanho zvinangwa sekutakura mumwe mutoro uye kureruka uremu.
