With the improvement of people's living standards, people began to pursue a high level of life, high quality, more and more people choose theater as a place for leisure and entertainment, but they also put forward a higher level of the theater's environment and sound effects.
Therefore, the decoration of the theater includes considerations of the influence of the building structure on the shape and symmetry diffusion, acoustic reflection, reverberation and the acoustic defects of the builder, and the use of the sound absorbing material is determined based on the results of the acoustic measurement.
As the name, sound absorbing materials have a strong absorption effect on sound, thus achieving the effect of noise reduction. However, the types of sound-absorbing materials that exist in the market are complex and diverse, and each type of sound-absorbing material has its own characteristics. The melamine sponge supplied by Life Nano-Plastic Product (Zhangzhou) Co., Ltd is a three-dimensional network structure with extremely high opening ratio characteristics (the opening ratio of Mina-melamine foam with a density of 9kg/M3 is over 99%) The sound wave can be easily and efficiently entered into the deep layer of the foam and converted into a mesh vibration energy can be consumed and absorbed, and the reflected wave is effectively eliminated, and the sound absorption coefficient is as high as 0.95, effectively absorbing the thunderous sound of the theater from multiple angles. To reduce the sense of vibration. The melamine sponge will gradually replace the commonly used sound absorbing and insulating materials such as glass wool, felt, ordinary foam, polyurethane, asbestos, polystyrene and polyethylene, and become a new sound absorbing product that is attracting attention in the market.
Suspended sound absorbing panels made with melamine sponges are used in public buildings such as theaters, shooting ranges, stadiums and ice rinks to reduce noise. Its high sound absorption, lighter weight, higher fire safety and simple cable construction technology are well represented in these applications. Acoustic plates with decorative uses, suspended sound absorbers, and metal ceiling plates supported by melamine sponges have significant improvements in acoustic effects.
In addition to sound absorption, the theater is a public place with a large flow of people, and fire resistance is also taken into consideration. Many sound absorbing materials can actually achieve B2 flame retardant, but less B1 flame retardant, and nano melamine sponge meets GB/T8624-2006 B1 flame retardant standard, and does not need to add flame retardant media. After contact with the flame in the theater, the surface layer is slightly ignited, and coking is formed, and the fire is self-extinguishing. When the surface layer is slightly ignited, nitrogen and carbon dioxide are released, which has fire extinguishing property, does not produce toxic smoke (smoke density <15), does not flow, Therefore, the incidence of fire accidents can be greatly reduced, and it is a very good new fireproof material.
Application
Based on the above factors, the sound absorption material of the theater is the first choice of melamine sponge, which has good sound absorption effect and integrates many characteristics such as fire prevention, decoration and heat insulation. It is a rare new theater sound absorption material. For more details, please contact sales@lfsponge.com, the developer and application service provider of melamine foam.
