China's high-speed rail construction and development are advancing by leaps and bounds. China's high-speed rail has grown from nothing to a world leader, and has gradually become China's business card and has become famous all over the world. The great convenience and comfortable riding experience that railway transportation brings to our daily travel is indispensable with a high-quality screen door sealing brush.

The door sealing brush is an important "green leaf role" on the screen door of rail transit. The sealing brush is installed on the left and right sides and above the screen door. So why do you need to use a sealing brush on a screen door? There are four main reasons.

1. When the high-speed rail train is moving forward at high speed, especially when passing through a tunnel, it will drive the air in the tunnel to flow at a high speed and produce "piston wind". The sealing brush will now take on the task of keeping the space sealed and dustproof. , Maintain good sealing and air tightness.

2. The fast running of the train will also bring a lot of noise. After installation, it can also reduce the discomfort caused by the noise and improve the passengers' good riding experience.

3. The sealed brush also has a good energy saving and environmental protection effect. When the car door switch is closed, it is easy to exchange hot and cold gas. The heat brought by the brake when the train enters the station will enter the waiting area. The entrance and exit of the platform will inhale the cold load formed by the air due to the piston effect of the train. And the cold and hot air in the tunnel are easy to be sucked away. The brush filaments are evenly distributed and the density is high. After installation, it can maintain 98.5% airtightness, which has a good energy-saving effect.

4. The sealed brush is flame-retardant. The brush wire with flame retardant function is not easy to be burned. Unfortunately, a fire incident in the car compartment can reduce the secondary damage caused by combustibles. (UL94-V0 grade brush filament burns for 10 seconds, the flame will be quickly extinguished within 30 seconds, and no burning material drips, and the combustion gas is non-toxic).

The aluminum alloy bracket of the screen door sealing brush can match a variety of door bodies. The styles are rich and diverse. The commonly used types are H, F, Y, and T. Aoqun manufacturers have a total of more than 70 styles for customers to choose from. More than one hundred high-speed railway trains have customized screen door sealing brushes that meet national standards, and provide customized services that can be customized with drawings, samples and designs according to customer needs.

Aoqun Brush brand screen door sealing brushes have passed SVHC testing and meet ROHS EU standards; sealed brushes that reach UL94-V0 flame retardant level meet EN45545-2 EU fire and flame retardant smoke toxicity test requirements, and are non-toxic, low-smoke, and non-toxic. Passed the Bombardier smoke density test; the pure nylon brush filament has good flexibility and strong recovery. It has passed the non-deformation test of the wool filament through one million high-speed running tests. The product quality is worthy of your trust.
