Ndi chitukuko cha ukadaulo wopanga zinthu zophatikizika, komanso kumvetsetsa kwakuzama komanso kumvetsetsa kwazinthu zophatikizika mumakampani opanga njanji, komanso kupita patsogolo kwaukadaulo kwamakampani opanga magalimoto oyendera njanji, kuchuluka kwazinthu zophatikizika pamagalimoto apamtunda kwakhala. kukulitsidwa pang'onopang'ono.Mitundu, magiredi ndi ukadaulo wazinthu zophatikizika zomwe zimagwiritsidwa ntchito zikukulanso nthawi zonse.

Kugwiritsa ntchito FRP mu Magalimoto a Rail Transit

1. Kugwiritsa ntchito FRP koyambirira pamagalimoto apanjanji

Kugwiritsiridwa ntchito kwa FRP m’magalimoto oyendera njanji kunayamba m’zaka za m’ma 1980, ndipo kunayamba kugwiritsidwa ntchito m’masitima apamtunda opangidwa ndi 140km/h othamanga kwambiri.Kuchuluka kwa ntchito kumaphatikizapo:

● khoma lamkati lamkati;

● mbale yapamwamba yamkati;

● Chimbudzi cha pulasitiki chopangidwa ndi galasi;

Cholinga chachikulu cha ntchito panthawiyo chinali Katsukiyogi.Mtundu wa FRP wogwiritsidwa ntchito ndi unsaturated polyester resin FRP.

2. Kugwiritsa ntchito gulu la FRP pamagalimoto apanjanji

Kugwiritsa ntchito gulu la FRP pamagalimoto a njanji ndi kukhwima kwake pang'onopang'ono kudachitika m'ma 1990.Amagwiritsidwa ntchito makamaka popanga magalimoto onyamula njanji ndi magalimoto apamtunda wamatawuni:

Khoma lamkati la chipinda cha alendo;

● mbale yamkati yamkati;

Anasonkhana galasi CHIKWANGWANI analimbitsa pulasitiki chimbudzi;

Integral galasi CHIKWANGWANI analimbitsa pulasitiki bafa;

Integral galasi CHIKWANGWANI analimbitsa pulasitiki chochapira;

FRP air-conditioning duct, zinyalala ngalande;

● Mpando kapena mpando.

Panthawiyi, cholinga chachikulu cha ntchito chasintha kuchoka m'malo mwa nkhuni kupita ku kuwongolera kuchuluka kwa magalimoto;Mitundu ya FRP yomwe imagwiritsidwa ntchito akadali makamaka unsaturated polyester resin FRP.

3. M'zaka zaposachedwa, kugwiritsa ntchito FRP pamagalimoto apamtunda

Kuyambira kumayambiriro kwa zaka za zana lino, FRP yakhala ikugwiritsidwa ntchito kwambiri pamagalimoto apamtunda.Kuphatikiza pa kugwiritsidwa ntchito popanga zinthu zomwe tatchulazi, zimagwiritsidwanso ntchito kwambiri popanga:

● Chophimba padenga;

Njira yatsopano yopangira mpweya padenga;

● Zigawo zosiyanasiyana zokhala ndi mawonekedwe ovuta m'galimoto, kuphatikizapo makoma amkati okhotakhota atatu-dimensional ndi mapanelo a denga;mapepala ophimba amitundu yosiyanasiyana yapadera;galasi CHIKWANGWANI analimbitsa pulasitiki zisa khoma mapanelo;zokongoletsa mbali.

Cholinga chachikulu cha ntchito ya FRP pakadali pano ndikupanga magawo omwe ali ndi zofunikira zapadera kapena zovuta zofananira.Kuphatikiza apo, kukana moto kwa FRP komwe kumagwiritsidwa ntchito pagawoli kwasinthidwanso.Zokhazikika komanso zowonjezera lawi retardant unsaturated polyester resin FRP yakhala ikugwiritsidwa ntchito kwambiri, ndipo kugwiritsa ntchito phenolic resin FRP kwachepa pang'onopang'ono.

4. Kugwiritsa ntchito FRP mu EMU yothamanga kwambiri

Kugwiritsa ntchito FRP mu ma EMU a njanji zothamanga kwafika pamlingo wokhwima.chifukwa:

(1) FRP imagwiritsidwa ntchito popanga magawo omwe ali ndi ntchito zapadera, mawonekedwe ovuta ndi mapangidwe, komanso magwiridwe antchito abwino kwambiri omwe amatha kupirira katundu wamkulu, monga FRP yolumikizana bwino, ma module akutsogolo ndi kutseka kwamakina, denga la aerodynamic shrouds, ndi zina.

(2) Magalasi opangidwa ndi pulasitiki opangidwa ndi galasi (SMC) amagwiritsidwa ntchito kwambiri

Kugwiritsiridwa ntchito kwa magalasi opangidwa ndi magalasi opangidwa ndi pulasitiki kuti apange mapanelo othamanga kwambiri a EMU okwera mkati mwamagulu ali ndi ubwino wotsatirawu:

The dimensional kulondola kwa zigawo ndi mkulu;

● Ubwino wopanga zinthu komanso kuchuluka kwazinthu,

● Anakwanitsa kupepuka;

●Zoyenera kupanga zambiri za uinjiniya.

(3) Sinthani mulingo wa FRP womwe umagwiritsidwa ntchito m'malo ena

● Itha kupangidwa kukhala magawo okhala ndi mawonekedwe osiyanasiyana ngati pakufunika;

Maonekedwe abwino ndiabwinoko, ndipo mawonekedwe ndi mawonekedwe ake ndi olondola kwambiri;

● Mtundu wa pamwamba ndi chitsanzo zikhoza kusinthidwa nthawi imodzi.

Panthawiyi, kugwiritsa ntchito FRP kumaphatikizapo kukwaniritsidwa kwa ntchito zapadera ndi mawonekedwe, ndi zolinga zapamwamba monga kunyamula katundu wina ndi kulemera kwake.
