Ndi chitukuko cha ukadaulo wopanga zinthu zopangidwa ndi zinthu zosiyanasiyana, pamodzi ndi kumvetsetsa kwakukulu ndi kumvetsetsa kwa zinthu zopangidwa ndi zinthu zosiyanasiyana m'makampani opanga magalimoto a sitima, komanso kupita patsogolo kwaukadaulo kwa makampani opanga magalimoto a sitima, kuchuluka kwa zinthu zopangidwa ndi zinthu zosiyanasiyana m'magalimoto oyendera sitima kwakula pang'onopang'ono. Mitundu, magiredi ndi milingo yaukadaulo ya zinthu zopangidwa ndi zinthu zosiyanasiyana zomwe zimagwiritsidwa ntchito zikukulirakulira nthawi zonse.

Kugwiritsa Ntchito FRP mu Magalimoto Oyendera Sitima

1. Kugwiritsa ntchito koyamba kwa FRP m'magalimoto oyendera sitima

Kugwiritsa ntchito kwa FRP m'magalimoto oyendera sitima kunayamba m'ma 1980, ndipo kunayamba kugwiritsidwa ntchito m'magalimoto amagetsi othamanga pang'ono opangidwa mdziko muno a 140km/h. Ntchito yake ikuphatikizapo:

● khoma lamkati;

● mbale yamkati ya pamwamba;

● Chimbudzi chapulasitiki cholimbikitsidwa ndi ulusi wagalasi;

Cholinga chachikulu chomwe chinkagwiritsidwa ntchito panthawiyo chinali Katsukiyogi. Mtundu wa FRP womwe unkagwiritsidwa ntchito ndi unsaturated polyester resin FRP.

2. Kugwiritsa ntchito FRP pa magalimoto oyendera sitima

Kugwiritsa ntchito kwa FRP pamagalimoto oyendera sitima ndipo kukhwima kwake pang'onopang'ono kunachitika m'ma 1990. Amagwiritsidwa ntchito makamaka popanga magalimoto oyendera sitima ndi magalimoto a sitima zapamsewu:

Khoma lamkati la chipinda cha alendo;

●Mbale yamkati ya pamwamba;

Chimbudzi chapulasitiki cholimbikitsidwa ndi ulusi wagalasi;

Bafa la pulasitiki lolimba ndi ulusi wagalasi;

Chimbudzi chapulasitiki cholimbikitsidwa ndi ulusi wagalasi;

njira yoziziritsira mpweya ya FRP, njira yotulutsira zinyalala;

● Chimango cha mpando kapena mpando.

Pakadali pano, cholinga chachikulu chogwiritsira ntchito chasintha kuchoka pakusintha matabwa kupita ku kukweza mtundu wa magalimoto; mitundu ya FRP yomwe imagwiritsidwa ntchito ikadali unsaturated polyester resin FRP.

3. M'zaka zaposachedwapa, kugwiritsa ntchito FRP m'magalimoto a sitima

Kuyambira pachiyambi cha zaka za m'ma 1900, FRP yakhala ikugwiritsidwa ntchito kwambiri m'magalimoto oyendera sitima. Kuwonjezera pa kugwiritsidwa ntchito popanga zinthu zosiyanasiyana zomwe zatchulidwazi, imagwiritsidwanso ntchito kwambiri popanga:

●Chinsalu cha padenga;

Mpope watsopano wopumira mpweya padenga;

●Zinthu zosiyanasiyana zokhala ndi mawonekedwe ovuta mgalimoto, kuphatikizapo makoma okhala ndi miyeso itatu komanso madenga am'mbali; makoma okhala ndi mawonekedwe osiyanasiyana apadera; makoma okhala ndi ulusi wagalasi wolimbikitsidwa ndi pulasitiki wopangidwa ndi uchi; zinthu zokongoletsera.

Cholinga chachikulu cha kugwiritsa ntchito FRP pagawoli ndikupanga zida zokhala ndi zofunikira zapadera kapena zofunikira zovuta zowonetsera. Kuphatikiza apo, kukana moto kwa FRP komwe kumagwiritsidwa ntchito pagawoli kwakhala bwino. Reactive and additive flame resins unsaturated polyester resin FRP yagwiritsidwa ntchito kwambiri, ndipo kugwiritsa ntchito phenolic resins FRP kwachepa pang'onopang'ono.

4. Kugwiritsa ntchito FRP mu EMU yothamanga kwambiri

Kugwiritsa ntchito FRP mu ma EMU a sitima zapamtunda kwafika pachimake chifukwa:

(1) FRP imagwiritsidwa ntchito popanga ziwalo zomwe zili ndi ntchito zapadera, mawonekedwe ndi kapangidwe kovuta, komanso magwiridwe antchito abwino kwambiri omwe amatha kupirira katundu waukulu, monga ma FRP integral streamlined fronts, ma module otsegulira ndi kutseka kutsogolo, ma shelufu a denga, ndi zina zotero.

(2) Pulasitiki yolimbikitsidwa ndi ulusi wagalasi (SMC) yakhala ikugwiritsidwa ntchito kwambiri

Kugwiritsa ntchito pulasitiki yolimba ndi ulusi wagalasi wopangidwa kuti apange makoma othamanga kwambiri amkati mwa EMU okhala ndi makoma ambiri m'magulu kuli ndi ubwino wotsatira:

Kulondola kwa magawowo kuli kwakukulu;

●Ubwino wopanga ndi mtundu wa zinthu,

●Yopepuka;

● Yoyenera kupanga zinthu zambiri zaukadaulo.

(3) Kukweza mulingo wa FRP womwe umagwiritsidwa ntchito m'zigawo zina

●Ingapangidwe m'zigawo zokhala ndi mawonekedwe osiyanasiyana ngati pakufunika;

Ubwino wa mawonekedwe ndi wabwino, ndipo mawonekedwe ndi kukula kwa ziwalozo ndi zapamwamba kwambiri;

● Mtundu ndi mawonekedwe a pamwamba zimatha kusinthidwa nthawi imodzi.

Pakadali pano, kugwiritsa ntchito FRP kumaphatikizapo kukwaniritsa ntchito ndi mawonekedwe apadera, ndi zolinga zapamwamba monga kunyamula katundu winawake ndi kulemera kopepuka.
