Main features of the sound insulation board: Under the premise of ensuring sound absorption and sound insulation, it is characterized by simple production and installation.
1. Large sound insulation: The average sound insulation is 37dB. (Conditional sound-absorbing cotton 48K, thickness 95 × height 500 × length 1000-3000)
2, high sound absorption coefficient: the average sound absorption coefficient of 0.84. (Conditional sound-absorbing cotton 48K, thickness 95 × height 500 × length 1000-3000)
3, weathering durability: the product has water resistance, heat resistance, UV resistance, no degradation due to rain temperature changes or quality abnormalities. The product noise barrier is galvanized on the surface of the endurance board, galvanized endurance board, glass wool and H steel column for more than 15 years.
4, the soundproof board is beautiful: a variety of colors and shapes can be combined to coordinate with the surrounding environment to form a beautiful landscape.
5, sound insulation board economy: assembly-type construction, improve work efficiency, shorten construction time, can save construction costs and labor costs.
6, the soundproof board is convenient: parallel installation with other products, easy to maintain, easy to update.
7. Safety of sound insulation board: Both ends of the sound absorption board are connected and fixed by Φ6.2 steel wire rope to prevent secondary damage, resulting in loss of personnel and property.
8. The soundproof board is light: the sound absorbing board series has the characteristics of light weight and the flat meter quality is less than 20 kg, which can reduce the load bearing capacity of the elevated light rail and elevated road and reduce the structural cost.
9. Soundproof board fireproof: Ultra-fine glass wool is used, because it has high melting point and is non-flammable, it fully meets the requirements of environmental protection and fire protection regulations, and fire protection reaches Class A.
10, high intensity: combined with different climatic conditions in various regions of China, the wind load is fully considered in the structural design. Using 1.0-1. 6mm galvanized sheet, through the numerical control equipment, the groove is pressed to increase the strength, so that the product is resistant to typhoon 10-12, and the pressure is 300kg/m2.
11ã€Waterproof and dustproof: The louver type design is fully considered waterproof and dustproof. The angle is set to 450 degrees. The sound absorption is not affected in the dust or rain environment. Dust drainage measures have been set in the structure to avoid Water accumulates inside the component.
12, the soundproof board is durable: the product design has fully considered the wind load of the road, the impact safety of the traffic vehicle and the open-air anti-corrosion of the whole climate. The product is galvanized on the surface of aluminum alloy endurance board, galvanized endurance board, glass wool and H steel column. The company guarantees that the product will not corrode, invariant, sound absorption and sound insulation within 15 years.
