In the construction engineering, the application of damping materials can reduce the harm caused by wind vibration on the one hand, and offset the natural period of the building from the earthquake period on the other hand, so as to minimize these natural hazards and ensure the safety of people's life and property. Generally speaking, the surface of sound insulation components of buildings should be relatively hard and dense materials. For the incident The sound wave has strong reflection, which greatly reduces the transmitted sound wave and thus plays a sound insulation role. However, the surface of sound-absorbing material is generally porous and soft, which has strong absorption and transmission to the sound wave incident on it, so that the reflected sound wave is greatly reduced. This is the main difference between sound absorption materials and sound insulation materials.
If the sound insulation materials are classified according to the use occasions, they can be mainly divided into building sound insulation materials, sound insulation devices and sound insulation in product equipment. The sound insulation materials for air acoustic buildings mainly include walls, doors, windows, etc. Because these materials are mainly used for building sound insulation, they do not need to be moved after they are completed, and they do not have high requirements for weight, and they also have very superior fire-retardant performance. Therefore, these materials generally have large density and relatively economic cost. Pcmape special fire-retardant damping block for building engineering vibration reduction and noise reduction is a good way to fill the gap in this regard, and provide excellent for the majority of high-end buildings High quality flame retardant, sound proof and damping material.
