Noise barriers material chooses the general rule is noise reduction effect the performance good, safe and reliable, material price structure, installation, lower cost, and economic durable, long service life, landscape coordination, beautiful and easy, and so on. Details are as follows:
(1) the sound insulation quantity: average sound insulation amount should be not less than 35 dB;
(2) the absorption coefficient tall: average absorption coefficient should be not less than 0.84; & NBSP;
(3) bears the weathering durability: product should have water resistance, heat resistance, anti ultraviolet ray and not because of the rain the temperature change decrease performance or the quality abnormal. Products using aluminum alloy plate, galvanization coil plate, glass cotton, H steel pillar surface corrosion in the galvanized Daniel of 15 years. & NBSP;
(4) beautiful: can choose a variety of colour and modelling for combination, and the surrounding environment harmonious, form beautiful scenery line.
(5) economy: fabricated construction, improve work efficiency, and shorten the construction time, can save ShiGongFei and Labour. & NBSP;
(6) convenient: and other products parallel installation and easy maintenance, update the convenient. & NBSP;
(7) light: sound-absorbing board series products have the characteristics of light weight, can reduce the elevated light rail, road bearing load, can reduce the cost structure.
(8) fire prevention: use superfine glass cotton, due to its high melting point, does not burn, fully meet the requirements of the code for fire protection and environmental protection.
(9) high strength: according to our country's regions different climate condition, the structure design of virtual wind load test when fully. Through the production line pressing grooves increase the intensity.
(10) waterproof, dustproof: material when the design mature waterproof, dustproof, dust or in the rain environment the influence of sound absorption performance, structure has set in discharging dust drainage measures, avoid component internal water. The perforation resonance cavity absorption in the sound absorption performance of the rain environment influence, in view of the low frequency noise reduction in particularly evident.
