The FRP cover plate is made of fiberglass and adopts the international advanced vacuum infusion process, which can be used as a bridge repair material. The material has been tested by the national glass and steel industry authority testing institution. The detection report shows that the performance of the vacuum infusion process FRP cover plate is significantly better than that of traditional hand paste technology. The comparison is as follows:
Product features of vacuum infusion process FRP products：
1, High density and low water absorption rate,
2, High strength, being anti-aging, anti-folding, anti-bending, strong deformation resistance;
3, Corrosion resistance and long service life;
4, Fatigue resistance is increased,the weight of the structure is reduced;
5, Strong resistance to UV radiation.
Compared with the traditional hand paste process,vacuum imported process FRP products has the characteristics below：
1, Excellent product property and high yield,
2, The product quality is stable, the repeatability is good,
3, Product integrity is good,
4, Good product precision,
5, Environmentally friendly.
Areas of application:
1. Odor gas collection system in sewage treatment plant
2. Exhaust gas collection system in waste treatment plant
