Nekuvandudzwa kwetekinoroji yekugadzira zvinhu zvakasanganiswa, pamwe nekunzwisisa kwakadzama uye kunzwisisa zvinhu zvakasanganiswa muindasitiri yekufambisa njanji, pamwe nekufambira mberi kwetekinoroji muindasitiri yekugadzira mota dzekufambisa njanji, huwandu hwekushandiswa kwezvinhu zvakasanganiswa mumotokari dzekufambisa njanji hwakawedzera zvishoma nezvishoma. Mhando, mamakisi uye mazinga ehunyanzvi ezvinhu zvakasanganiswa zvinoshandiswa zviri kuramba zvichivandudzika.
Mhando dzezvinhu zvakasanganiswa zvakashandiswa mumotokari dzechitima dzinosanganisira:
(1) FRP yepolyester resin isina kuguta uye yakaoma zvishoma;
(2) Phenolic resin girazi faibha yakasimbiswa plastiki;
(3) Reactive flame resins isina saturated polyester resin FRP ine simba guru;
(4) Chinowedzera murazvo chinodzivirira moto chisina kuzara polyester resin girazi rakasimbiswa nefiber plastic rine simba rakaderera zvishoma;
(5) Zvinhu zvekabhoni fiber.
Pakati pezvinhu zvakagadzirwa ndeizvi:
(1) Zvikamu zveFRP zvakaiswa nemaoko;
(2) Zvikamu zveFRP zvakaumbwa;
(3) Zvikamu zveFRP zvechimiro chesandwich;
(4) Zvikamu zvefayibha yekabhoni.
Kushandiswa kweFRP muMotokari dzeNjanji
1. Kushandiswa kwekutanga kweFRP mumotokari dzechitima
Kushandiswa kweFRP mumotokari dzechitima kwakatanga kuma1980, uye kwakatanga kushandiswa muzvitima zvemagetsi zvinofamba nemhepo inomhanya 140km/h zvinogadzirwa munyika. Basa rekushandisa rinonyanya kusanganisira:
● madziro emukati memadziro;
● ndiro yepamusoro yemukati;
● Chimbuzi chepurasitiki chakasimbiswa negirazi chakasanganiswa;
Chinangwa chikuru chekushandisa panguva iyoyo chaive Katsukiyogi. Rudzi rweFRP rwakashandiswa i unsaturated polyester resin FRP.
2. Kushandiswa kweFRP pamotokari dzinotakura vanhu nechitima
Kushandiswa kweFRP pamotokari dzinotakura vanhu nechitima uye kukura kwayo zvishoma nezvishoma kwakaitika muma1990. Inonyanya kushandiswa pakugadzira mota dzinotakura vanhu nechitima dzinotakura vanhu nechitima dzinofamba mumaguta:
Chidziro chemukati meimba yevaenzi;
●Pfuti yepamusoro yemukati;
Chimbuzi chepurasitiki chakasimbiswa negirazi chakaunganidzwa;
Imba yekugezera yepurasitiki yakasimbiswa negirazi;
Imba yekugezera yepurasitiki yakasimbiswa negirazi;
mugero wemhepo unotonhodza FRP, mugero wekubvisa tsvina;
● Chigaro kana furemu yechigaro.
Panguva ino, chinangwa chikuru chekushandisa chachinja kubva pakutsiva huni kuenda pakuvandudza mhando dzemotokari; mhando dzeFRP dzinoshandiswa dzichiri kunyanya unsaturated polyester resin FRP.
3. Mumakore achangopfuura, kushandiswa kweFRP mumotokari dzechitima
Kubva pakutanga kwezana remakore rino, FRP yave ichishandiswa zvakanyanya mumotokari dzechitima. Pamusoro pekushandiswa mukugadzira zvigadzirwa zvakasiyana-siyana zvataurwa pamusoro apa, inoshandiswawo zvakanyanya mukugadzira:
●Chifukidziro chedenga;
Mugero mutsva wemhepo uri padenga;
●Zvinhu zvakasiyana-siyana zvine maumbirwo akaomarara mumota, zvinosanganisira mapaneru emadziro emukati akakombama ane mativi matatu uye mapaneru edenga repadivi; mapaneru ekuvhara emhando dzakasiyana-siyana; mapaneru emadziro epurasitiki akasimbiswa negirazi; zvikamu zvekushongedza.
Chinangwa chikuru chekushandisa FRP padanho rino ndechekugadzira zvikamu zvine zvinodiwa zvakakosha kana zvinodiwa zvakaoma zvemuenzaniso. Pamusoro pezvo, kuramba moto kweFRP kunoshandiswa padanho rino kwavandudzwawo. Reactive uye additive flame retardant unsaturated polyester resin FRP yave ichishandiswa zvakanyanya, uye kushandiswa kwephenolic resin FRP kwakadzikira zvishoma nezvishoma.
4. Kushandiswa kweFRP muEMU inomhanya zvakanyanya
Kushandiswa kweFRP mumagetsi ekukurumidza echitima EMU kwasvika padanho rekukura zvechokwadi. Nekuti:
(1) FRP inoshandiswa mukugadzira zvikamu zvine mabasa akakosha, maumbirwo akaomarara uye maumbirwo, uye kushanda kwakanaka kwazvo kunogona kutsungirira mitoro mikuru, senge maFRP integral streamlined fronts, ma front-end opening and closing mechanism modules, denga re aerodynamic shrouds, nezvimwewo.
(2) Plastic yakaumbwa nefiber yakasimbiswa negirazi (SMC) yakashandiswa zvakanyanya
Kushandiswa kwepurasitiki yakasimbiswa negirazi yakagadzirwa nefiber kugadzira madziro emukati mevanhu vane EMU anomhanya zvikuru muzvikamu zvakasiyana-siyana kune zvakanakira zvinotevera:
Kururama kwezvikamu kwakakwirira;
●Hunhu hwekugadzira uye giredhi rezvigadzirwa,
●Yakareruka;
●Yakakodzera kugadzirwa kwemainjiniya.
(3) Kuvandudza huwandu hweFRP inoshandiswa mune zvimwe zvikamu
●Inogona kugadzirwa kuita zvikamu zvine magadzirirwo akasiyana-siyana sezvinodiwa;
Hunhu hwekutaridzika huri nani, uye kurongeka kwechimiro nehukuru hwezvikamu zvakakwirira;
●Ruvara rwepamusoro uye patani zvinogona kugadziriswa panguva imwe chete.
Panguva ino, kushandiswa kweFRP kunosanganisira kuzadzikiswa kwemabasa akakosha nemaumbirwo, uye zvinangwa zvepamusoro-soro zvakaita sekutakura mutoro wakati uye huremu hwakareruka.
