Damping series
1.Product composition
TD09 damping plate is made of damping glue, adding flame retardant, damping filler, crosslinking agent, etc. It is black flat block material, carton packaging, and pasted with damping glue (paste).
2.Product characteristics
This product can effectively suppress structural vibration and noise caused by structural vibration, with excellent vibration and noise reduction performance, suitable for the use of various thickness of the substrate with a flat surface, its average vibration attenuation efficiency of 49.2%, can reduce noise 5 ~ 20db.

4.Design use parts and thickness
1, the design and use of parts: vibration generated parts (vibration source) such as the bottom and wall of the engine room of the ship, above the propeller, the bottom and wall of the large air conditioning room; The parts requiring higher comfort in the vibration transmission path (vibration transmission path), such as: the bottom and wall of the ship's control room, instrument equipment room, crew lounge, etc.; Other aspects such as ventilation pipe outer wall, steel structure building top steel plate inside, soundproof doors and Windows steel plate inside.
2,Design thickness: The total thickness is 1.5 ~ 2 times that of the base steel plate. For example, if the thickness of the substrate steel plate is 8mm, the total thickness is (12 ~ 16) mm. If the damping paste is used, the Design thickness of the damping paste is ~ 2㎜.
