The sound insulation raw material is a nano-multi-layer structure material. The sound insulation and noise reduction effect of the coating depends on its loss factor, forming a damping constraint structure. When sound strikes the pipe wall and starts to produce sound and vibration, the sound insulation damping coating on the pipe wall will form a damping protective layer on the pipe, increasing the pipe density and effectively converting the mechanical energy of the sound wave into heat energy for dissipation. This significantly enhances the sound insulation effect of the wall panels.
