Damping steel plates have excellent sound insulation properties. Mainly in the sound transmission loss measurement and theoretical calculations show the following characteristics:? It can inhibit high-frequency kissing effect and low-frequency *** vibration.? It can make the anastomosis frequency to the high frequency direction, the more out of the ordinary mechanical noise applicable range.? The sound transmission loss of multi-layer damping steel plate can be more reduced.
We all know that noise is the enemy of people's life and work. People who live in the noise for a long time will suffer from vegetative nerve dysfunction, so that low fever, chest pain, and even the loss of walking ability. Now this problem can be solved. Scientists have pioneered a new material called composite damping steel. "Damping" means to dissipate energy, in this case noise. It blocks the noise at the point where it is generated. According to a test, if the floor of a school gymnasium is paved with this steel plate, the classrooms and the library underneath it remain quiet, even though intense sports competitions generate very strong noise. If the workshop with this kind of steel plate for the wall, the workshop motor roar, the sound of machinery will be difficult to go beyond the scope of the workshop to harm others.
So what is this composite damping steel plate made of? We have found in our daily lives, a variety of materials have different sound-absorbing capacity. Some knock on it to make a clanking sound, while others make a dull purr sound. Obviously, the latter is a better noise damping material. Has been determined to belong to this material has certain viscoelastic polymer materials. This material is sandwiched between two or more layers of steel plate, it becomes a composite damping steel plate. It can not only sound insulation, but also heat insulation, waterproof. Therefore, its scope of use is expanding, becoming a promising new building materials.
