Wooden sound-absorbing board fire, building sound building materials (certified), Tangshan wooden acoustic panel

Wooden sound-absorbing board fire, building sound building materials (certified), Tangshan wooden acoustic panel built by the Guangzhou Building Materials Co., Ltd. to provide sound. Building Materials Co., Ltd. Guangzhou to build sound (www.jianyinjc.com/) is specialized in "panels, acoustic panels, inorganic fiber coating" of the enterprise, the company of "honesty, hard service" concept, to provide you with the most quality products and services. Welcome to inquire! Contact: Li Guirong. Insulation blankets Description: This product is the introduction of advanced US technology and equipment, the anti-aging and corrosion resistant PVC rubber dozen organic minerals refined in accordance with a certain percentage of the studio wooden panels, acoustic panels of wood products for the black walls, outside with a layer of sound-absorbing non-woven fabric, odor-free environment, the low-frequency and high-frequency sounds are quite good inhibitory effect, can effectively inhibit the spread of a variety of sounds. Product performance: superior noise performance: high sound insulation, single-layer material amount of noise 22-29dB (A). Flexible wooden panels, high elongation force. Insulation, anti-cold. Tired of burning, self-extinguishing. Corrosion, waterproof, good aging resistance. Construction is simple: because of thin, flexible, easy to use tools such as utility knife can cut. Especially non-woven composite surface, making adhesive, fixed easier KTV bar wooden panels, can effectively improve the construction efficiency. Some sound insulation board is installed in the rubber layer between the two plates, or acoustic damping material made of felt, etc., using this method, the effect of noise can be improved in the near future in a certain extent, high-performance sound insulation board market, but its sound effects decreased over time. Is well known, the aging of rubber and other materials in the air will slowly, which gradually harden and cause loss of elasticity, resulting in the effect of noise is gradually reduced with time. On the other hand, the installation of rubber layer or layers of insulation blankets in the middle of two plates approach, the project cost is very high. In order to achieve good sound insulation, sound insulation boards must be very simple installation method, otherwise it is difficult to achieve the desired effect of noise. Professional acoustic engineers are aware of a wall in the laboratory can detect if X decibels of noise, in practical engineering often only soundproof X-2 dB or less sound insulation. Caused mainly wall insulation value below the value of practical engineering laboratory for two reasons: the quality of the actual project includes installation of lateral sound transmission problems, and practical engineering installation quality inferior wall caused by laboratory professionals a. Thus, panels must be simple to install, otherwise the site installation personnel there will be mistakes, resulting in less noise wall insulation value of the target. For example, the elastic bar in the United States have been used more, which in itself is a good acoustic instruments and products in the laboratory using an elastic bar lightweight plaster wall of sound effects can be increased 5-10 dB, However, in practical engineering, installation workers often are not able to accurately plate mounted on the elastic bar, causing the wall to improve the actual sound effects are very limited. Therefore, in recent years, the United States has gradually abandoned this wall insulation techniques and tools.
