Specializing in the production of custom Hao Feng railroad railway noise barrier wall insulation and sound absorbing panels are available upon request given ..

Selection of sound in the communication process, when you encounter the sound barrier, it will happen reflection, transmission and diffraction three phenomena. Usually we think that the barrier be able to stop the spread of the direct sound, and sound have sufficient attenuation transmission while transmitting sound effects can be ignored. Therefore, sound effects sound barrier noise amount may generally be said that it reflects the sound barrier above two acoustically transparent shield skills. Between the sound source and the receiving point insert a sound barrier, set up barriers infinite sonic barrier above only diffracted from the past, and in the subsequent formation of an acoustic shadow zone, as the light is blocked by the formation of a shadow as the object. In this acoustic shadow area, people can feel the noise significantly reduced, and this is the sound barrier noise reduction effect. The principle of sound barrier material selection, the general principle is good noise reduction performance, structural safety and reliability, material 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 prospects Edit this paragraph advantages fold fold 1, low cost: only low production costs, and because the product is light weight can significantly reduce the bearing load elevated light rail, elevated road, reducing construction costs; 2, to withstand strong wind load: high strength, weight Light can meet different climatic conditions on wind load requirements of each region; 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: Magnesite cementitious materials are inorganic non-combustible materials, sound-absorbing composite of 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, using durability: Magnesite sound barrier water-resistant, fire-resistant, corrosion-resistant, anti-UV, from rain, snow, wind and sand erosion and other inclement weather, long life; 6, easy installation: Magnesite sound barrier, light weight, can be Prefabricated construction, high efficiency, short construction period, 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 achieve landscape decorative requirements. 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.
