XG Composite Noise-absorption Plate with Rail Surface
Introduction
XG  composite noise-absorption plate with rail surface is developed independently by our company, which has been applied for China's patent.
XG composite noise-absorption plate with rail surface is produced by that different materials and layers are molded at the same time. The surface and bottom are single-graded concretes of different aggregates and gradations. And the surface is treated by special nano photocatalyst. Due to the principle of photocatalysis, this noise-absorption material has effects of purifying NOx in the air. Meanwhile, in the presence of solar radiation, evaporation occurs because of the temperature difference between the surface and underground, so this material also plays a role in water storage. The evaporation of water is an endothermic process for large amounts of sensible and latent heat being absorbed. Therefore, this can effectively alleviate the heat island effect.
Advantages
(1) Noise absorption. XG composite noise-absorption plate with rail surface can make use of the air viscous drag and heat conduction to reduce the noise, even to achieve the optimum effect of uniform absorption in full frequency. XG noise-absorption material with soft surface has the advantages of absorbing noise with wide band and good performance in noise reduction. The sound absorption coefficient can reach 0.6.
(2) Economy. Compared with other similar international noise-absorption materials, XG with soft surface has a price advantage since it can be produced on a large scale with mature and advanced manufacturing technologies.
(3) Fire prevention, water resistance & thermal insulation. Because of the XG is inorganic material, it is flame retardant. This material is a non-flammable one (Grade GB8624A) tested by the state authority. But other materials are only Grade "B".
(4) Anti-glare. This material is one kind of matt materials and it has anti-glare effect. It's very suitable for safe driving.
(5) Corrosion resistance. For the main material of XG plate with rail surface is chemically stable, it has an advantage of corrosion resistance.
(6) Environmental friendliness, self-cleanness & aesthetic appearance. The raw materials of XG are non-toxic, harmless and non-radioactive inorganic ones, hence they are environmentally friendly. The OH free radicals formed by additives therein can reduce formaldehyde, benzene and other organic substances in the air to harmless substances. Besides, it's self-clean as a result of its hydrophobicity and lipophobicity.
If you need, XG noise-absorption material with soft surface can be made into various patterns, sizes and colors.
