Analysis on the Future Development Trend of Environmental Sound Absorber Industry

Environmental sound absorber industry belongs to a special industry。 At the same time, many entrepreneurs and bosses, including customers and friends, will consider the same question, that is, where will the future trend of sound absorber go? Plus this year is so bad。 It's just worse! Following is the sound absorption board rules and regulations form for your reference! ___________

 

 

 

Sound Absorbing Material (Sound Absorbing Material): Any material can absorb sound, but the degree of absorption is very different。 Usually, the material whose average absorption coefficient of the above six frequencies is greater than 0。2 is classified as sound absorption material。 Sound-absorbing materials/sound-absorbing materials are mostly porous materials, such as slag cotton, blankets and so on。 The sound-absorbing mechanism is that sound waves penetrate into the pore of the material, and the pore is mostly an open hole through each other, which is subject to friction and viscous resistance of air molecules, as well as mechanical vibration of fine fibers, so that sound energy can be transformed into heat energy。 The sound absorption coefficient of this kind of porous material increases gradually from low frequency to high frequency, so the sound absorption effect of high frequency and medium frequency is better。

 

 

 

Sound-absorbing board is a kind of material with sound-absorbing and noise-reducing function, which is mainly used in cinema, concert hall, Museum exhibition hall, library, interrogation room, gallery, auction hall, gymnasium, lecture hall, multi-functional hall, hotel lobby hospital, shopping mall, school, piano room, conference room, studio, recording room, KTV private room, bar, industrial workshop, computer room, family noise-reducing and so on. Places requiring higher acoustic environment and high-grade decoration.

 

 

 

秒速时时彩投注On January 1, 2013, the National Development and Reform Commission and the Ministry of Housing, Urban and Rural Construction issued the Action Plan for Green Building. During the Twelfth Five-Year Plan period, 1 billion square meters of new green buildings were completed; by the end of 2015, 20% of new buildings in cities and towns met the requirements of green building standards. Subsequently, the implementation plans of the local governments on green building have been introduced one after another. The action plans cover the upstream building materials industry. In addition, with the rapid growth of China's construction industry and real estate industry, the improvement of people's living standards, the improvement of living comfort and the requirement of noise prevention, the demand for sound-absorbing panels has increased significantly. It has greatly promoted the rapid development of the industry. From January to December 2014, the total sales value of heat and sound insulation materials industry in China exceeded 37 billion yuan, and the export delivery value exceeded 1.2 billion yuan.
