Hao Feng specializes in producing customized highway sound barriers can be customized, welcome your calls ..

Outdoor sound barrier sound barrier structure generally use brick or concrete structures, interior sound barrier cited steel, wood ,, PMMA / POLYCARBONATE SHEET pull plastic, plasterboard and aluminum foam structure. Sound barrier consists of two parts of steel columns and suction insulation panel composed of members column is the main force of the sound barrier, it is fixed by bolts or welding on a road side barrier wall or rail embedded steel; absorbing insulation acoustic absorption panels are the main component, it is through high-strength spring clips to secure the H-type column groove formed sound barrier. Sound barrier design has been more fully into account the elevated highway, crash safety urban light rail, subway wind load, transport vehicles and all-weather outdoor corrosion problems. It is nice shape, producing exquisite, easy to transport, installation, low cost, long life, especially for the elevated highway and urban light rail, subway noise prevention use, is a modern urban best acoustic noise reduction facilities. 1m a sound barrier height between 5m to cover the effective area of ??the average noise 10 ~ 15dB (A) (125Hz ~ 40000Hz, 1/3-octave), up to 20dB (A). In general, the higher the sound barrier, or farther away from the sound barrier, the noise reduction, the better. Selection principles folded edit sound barrier material selection in this paragraph is the general principle of good performance noise reduction, structural safety and reliability, materials, affordable, low installation cost, durable, long life, landscape coordination, nice and so on. Specifically described as follows: (1) large noise: not less than the average amount of noise 35dB; (2) high absorption coefficient: the average absorption coefficient of not less than 0.84; (3) weather durability: The product should have the water resistance, heat, UV, rain temperature changes will not reduce the performance or quality of the exceptions. 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 with the surrounding environment, the formation tapestry. (5) Economic: prefabricated construction, improve work efficiency, shorten construction time, saving construction costs and labor costs. (6) Convenience: parallel with other products to install, easy maintenance, easy to replace. (7) Portability: sound-absorbing board series of products with light weight characteristics, load bearing reduce elevated light rail, elevated road, can reduce the cost structure. (8) Fire: superfine wool, because of its high melting point, non-flammable, fully meet the requirements of environmental protection and fire code. (9) High intensity: the combination of different climatic conditions of the region, in the structure designed to fully test the virtual wind loads. Increase the strength of the production line by pressing the groove. (10) waterproof, dustproof: material design takes full account waterproof, dustproof, dust or rain in the environment the sound absorption performance is not affected, construct drainage measures have been set for dust, avoid stagnant water inside member. Micro-perforated cavity resonance absorption of sound absorption performance in the rain affected the environment, for the low-frequency noise is particularly evident. (11) Durable: product design has been fully taken into account the wind load of the road, crash safety transportation vehicles 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. Advantages prospect 1, the cost is low: only low production costs, and because the product can significantly reduce the weight bearing load light elevated light rail, elevated road, reducing construction costs; 2, to withstand strong wind load: high strength, light weight, can meet our various different climatic conditions regions wind load requirements; 3, excellent acoustic performance: average noise magnesite sound barrier is greater than 35dB, the average absorption coefficient greater than 0.84 in all areas to meet the requirements of the sound barrier; 4, fire performance: Ling magnesium cementitious materials are inorganic non-combustible materials, composite acoustic glass wool, perlite and other materials also have good fire performance, making products with excellent fire performance, is a national A-level non-combustible material; 5, the use of durability: Magnesite sound barrier water, fire, corrosion, UV, from rain, snow, wind and sand erosion and other inclement weather, long life; 6, easy installation: Magnesite sound barrier, light weight, can be fabricated construction, high efficiency short duration, can save a lot of labor costs; 7, beautiful plastic: according to the different needs of the metal material structure can be used, and the transparent material combinations can also be painted in different colors and patterns to meet the requirements of landscape decoration. 8, energy saving: the magnesite sound barrier raw materials used non-toxic, and the production process without high temperature heating, no toxic gas release, the state encourages the development of environmentally friendly products; 9, broad scope of application: according to the different needs of machine production Link Magnesium and magnesium acoustic panel sound-absorbing panels for road transportation, rail, railways, culverts, tunnels and industrial plants, workshops and residential quarters and other fields.
