Supply Hao Feng cement sound barrier wall insulation cement customizable welcome your call upon request ..

Supply of cement concrete sound barrier sound barrier, sound barrier Anping Jinbiao specializing in the production of various sound barrier, sound barrier mason, soundproof walls, highway sound barriers, welcome customers come to purchase negotiations. Cement sound barrier inexpensive, has been recognized by our customers, the application of common. Cement sound barrier by the H-shaped steel column and soundproofing screen body composition. H-beam column: 125 * 125 * 6.5 * 9 * 3.0 meters Screen: Outsourcing aluminum and galvanized sheet, cement wood filler. Sonic 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 the system has enough radio sound attenuation, and transmits the sound effects are negligible. 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. Cement sound barrier mold has the following characteristics: a good sound-absorbing effect; second, to produce products of high intensity; three, good mold release, mold long life, product size accurately. The current center is planning a dream plan, before people did not ask for noise, and no one to manage today's requirements for people's quality of life improves, countries are also governance railway, highway, the highway noise. New, old railway, highway, highway sound barriers facing transformation projects, a new industry is emerging, a new opportunity in front of us, hope to have the eye of companies seize opportunities, common development and create a better future. Cement sound barrier, cement sound barrier noise barriers are four common types resistive barrier, ordinary transparent sound barrier, sound barrier as well microplates transparent composite sound barrier. A resistive resistive sound barrier sound barrier from the front panel, rear panel, side panels to form a closed box structure, form a modular unit. The front plate is perforated perforation rate of 25% of galvanized steel, rear panel and side panels for the non-perforated galvanized steel sheet (from an aesthetic point of view, can also be color plate). Filling between two layers of moisture-proof plate centrifugal glass wool board, sound-absorbing material covered with polyvinyl fluoride film. 12 # I-beam columns, column spacing 2m. Column inserted in the base of reinforced concrete inside. The standard plate is inserted between the beams, to be fixed with fasteners, installation, maintenance, replacement is very simple. Second, ordinary transparent noise barriers ordinary transparent noise barriers transparent polycarbonate plate (also known as PC board), because it is transparent, the landscape better sense of noise barriers, easier integration into the surrounding environment. Colors. Third, microplates transparent noise barriers microplates transparent noise barriers have two layers, it applied the porous sound absorption principle, in a lot of wear layer polycarbonate panel 0.8mm diameter holes, perforation rate 1 %. Another layer of polycarbonate sheet without perforations, the spacing between the two plates is 100mm. It is equivalent to a single microporous absorbing structure to solve the contradiction between the absorption and transparency. As the role of sound waves, microporous and it will not be clogged with dust. Fourth, the composite sound barrier composite sound barrier both the advantages of transparent and opaque Sound Barrier. Half of it is resistive sound barrier, and the other half is transparent noise barriers with two compounded by a more than four kinds of sound barrier height can be freely combined according to design requirements, the way the screen can also be customized according to customer requirements. Sonic 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 the system has enough radio sound attenuation, and transmits the sound effects are negligible. 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. Company Website: http: //www.chongkongban.org
