In the 1990s, with the sustained and stable economic growth, China's passenger car manufacturing industry has shown a trend of prosperity. Various brands of CRRC continue to appear, and the application layers of various new processes and materials can not afford to emerge. Among them, it is worth noting that FRP plate (hereinafter referred to as FRP) is used for large panels. FRP plate has the advantages of high aging resistance, high strength, light weight, thermal insulation, edge, sound insulation, long service life, bright and comfortable appearance and fast forming Many advantages, such as low investment, adapt to modernization, multiple varieties and small batch, and meet the performance and requirements of modern passenger cars, such as environmental protection, low fuel consumption, comfort, ride comfort, durability, reliability, power and moderation. FRP outer skin plate has become the choice of outer skin material for medium-sized passenger cars.
1. FRP avtobus tashqi teri plitasi bilan tanishish
FRP tashqi teri plitasi termoset plastik va mustahkamlangan shisha toladan iborat bo'lib, uning kuchi po'lat va alyuminiydan kattaroqdir. Mahsulot yumshoq va past haroratlarda deformatsiya va parchalanishni keltirib chiqarmaydi va issiqlik o'tkazuvchanligi past bo'ladi.
FRP tashqi teri plitasining zichligi 1,6 g / sm3, og'irligi po'lat plitalardan 4-5 baravar engilroq va mustahkamligi po'lat plitalardan 1,7 baravar yuqori. Shuning uchun FRP ning mexanik va fizik xususiyatlari po'latdan ko'ra yaxshiroqdir. Bu muhim muhandislik materialidir. Bu qiyin tozalash, oson tushkunlik va deformatsiya, qiyin o'rnatish, zaif chidamlilik, oson aşınma va yomon zarba qarshiligi kabi an'anaviy materiallarning muammolarini hal qiladi; Barcha xorijiy avtobus ishlab chiqaruvchilari FRP tashqi teri plitalaridan foydalanganlar
Mahsulot qarish, sarg'ayish va kuchli korroziy muhitda tozalanishi oson, bu gigienik talablarga javob beradi.
2. Avtobusga qo'llaniladigan FRP avtobus tashqi teri plitasini joriy etish jarayoni
FRP terisi butun FRP plitasini yopishtiruvchi orqali old / orqa devorga yoki tomning ramkasiga qo'llashdir. Katta egrilik bilan old / orqa devorning butun terisini FRP qismlari yordamida olish mumkin. U chiroyli shakli, qulay o'rnatish va ishlatish, past mehnat zichligi va ishlab chiqarish afzalliklariga ega. Shuning uchun u engil avtomobillar ishlab chiqarishda keng qo'llaniladi.
