So far, the total mileage of China's high-speed railways accounts for more than 60% of the global total mileage. In the future, China's high-speed railway construction will continue to maintain a high operating trend. By 2025, the total mileage of high-speed railway operations will exceed 38,000 kilometers. The high-quality screen door strip wire brush is a booster for China's high-speed rail to keep running at a high level.

So let me tell you how to judge a high quality screen door strip wire brush:

1. Filament is PA6 flame retardant straight wire φ0.15 ~ 0.4 ± 0.03mm. Dense and uniform thickness, moderate opening angle, no pressure scars, no cross filaments, no abnormal light leakage, no unevenness, and no length difference.

2. Pass the EU ROHS 10 limit requirements; pass the SVHC 169 high concern substance limit requirements; meet UL94-V0 test, melting point 218 ~ 224 ℃, heat distortion temperature 185 ~ 190 ℃, burn slowly when lit, white smoke , The inner layer of the flame is light blue and the outer layer is yellow; strip wire brush goes out within 10s of the fire, and no low objects fall off).

3. strip wire brush filaments with a length of 10mm are concentrated and the tensile strength is ≥10kg.

  Aoqun screen door strip wire brush has been applied to more than 80% of China's high-speed rail projects. It has witnessed 3,000 customers and serves more than 50 countries and regions around the world.
