Product description:

The damping devices are installed at the web of the rail, where the vibration is remarkable. The vibration energyis absorbed by the damping layer directly, leading to the molecule movementconverted into thermal energy. Outside the damping layer, rigid layer is added toimprove thenoise and vibration reduction. The device has an excellent capacity in reducing vibration and noise caused by the high energy exchange rate and the highloss factor in a broad temperature and frequency band.The deviceas the charactersof oil-proof, nonflammable, non-aging,etc., and is convenient to stick to the surface of the rail web.

Application fields:

Applied to many types of rails on low-noise reformation, according to different rail shapes.

Features:

1.The noise reduction in laboratory test is 1-3.5 dB(A), and it is remarkable in 1000~3000Hz.

2.The material is cost effective because of itshigh loss factor in a broad temperature and frequency band.

3.The material is nonflammable, non-aging, environmental friendly without harmful material such as heavy metal, halogen and asbestos.

4.The material has good stickiness, which can stick to the surface of the rail web directly. Also it is convenient to installthe material not only in factory but also on the site.

5.It will not corrode the rail, having no effect on the existing facilities or their maintenance.
