Similar barriers mold in the choice of basic and soundproof panels mold material selection, the principle is good noise reduction performance, structure safe, reliable, affordable materials, low installation cost, durable, long life, landscape coordination, nice and so on. Specifically as follows: (1) a large amount of noise: the average amount of noise should not be less than 35dB; (2) the sound absorption coefficient is high: the average absorption coefficient should be not less than 0.84; (3) weather Durability: The product should have a water resistance heat, UV, temperature changes will not degrade the performance of stormwater quality or abnormal. Products using aluminum coil, galvanized coil, glass wool, H galvanized steel column surface outside the grounds of anti-corrosion life of more than 15 years. (4) appearance: choose a variety of colors and shapes are combined, coordinated with the surrounding environment, the formation tapestry. (5) Economy: prefabricated construction, improve work efficiency, shorten construction time, saving construction costs and labor costs. (6) Convenience: parallel with other products to install, easy to maintain, easy to update. (7) Light: acoustic panels series has the characteristics of light weight, reduce the load bearing elevated light rail, elevated road, can reduce the cost structure. (8) Fire: The superfine wool, because of its high melting point, non-flammable, fully meet the requirements of environmental protection and fire code. (9) High intensity: a combination of different regions of the climatic conditions, structural design fully into virtual wind loads. Increase the strength of the recess by pressing production line. (10) waterproof, dustproof: material designed to fully consider the waterproof, dustproof, dust or rain environment in its sound absorption performance is not affected, construct drainage measures have been set for dust, avoid stagnant water inside components. Resonant cavity micro-perforated sound absorption in the rain sound absorption performance is not affected environment for low-frequency noise is particularly evident. (11) Durable: product design has been fully taken into account wind load road transport vehicle crash safety and full gas fake outdoor corrosion. Products using aluminum coil, galvanized coil, glass wool, H galvanized steel column surface. No corrosion within the warranty period, the same type, sound absorption, sound insulation effect is not reduced.
