  • Particulate Sound Barrier From China - China

    price: 10.00 Dollar US$

    Particles noise reduction material first select specific mesh inorganic particles, such as natural sand, slag particles and etc. And covering them with well-proportioned and ultrathin gel solvent on all the particle surface, thus they will form a certain angle coefficient coated particles. The particles under the action of external force which makes the surface of curing effect. The tiny particles will like be welded together. Between the particles, it will naturally form large, irregular, interconnected tiny pore.
    In the polymerization process, the ratio of particle size and polymerization method can be accurately controlled, which determines the size of the inner pore and their arrangement. Thus according to the actual demand, it can custom design and produce noise reduction product of different acoustic characteristics. This product will have many advantages of high strength, fire prevention, moisture proof, frost resistance and ageing resistance. Also by using green cementing material, particles products without any harmful volatile matter which is environment friendly acoustic material.
    Aluminum alloy plate and aluminum alloy pore plate are installed separately on both sides of sound barrier for high-speed railway bridge, and upper and lower ends are of trapezoidal convex-concave shape. Upon the completion of installation, mortise and tenon structure is formed to lengthen the diffraction length between barrier boards, and enhance sound insulation property.
    Barrier compounded polymeric particle material with aluminum alloy plate, which makes it weight light, and suitable for high-speed rail bridge section.
    Using polymeric particle sound-absorbing material to replace the existing sound-absorbing materials (glass wool, rock wool and etc.) and the surface of High-speed rail bridge sound barrier. Its structure is 1.2mmgalvanized steel plain sheet+10mmDamping plate+8mmparticulate absorbing board+0.8mmGalvanized hole plate.
