It can be seen from the table that the polyurethane sponge pore opening agent has a low elastic modulus and a high sound absorption coefficient, which is suitable for pipe systems that are shock-absorbing and noise-reducing.
2.2.2 Application Cases
The cooling water pipeline system of a power plant uses polyurethane sponge hole opening agent as shock and noise reduction material. After three months of operation, the noise of the pipeline system has been reduced by 10 dB, the vibration amplitude has been reduced by 30%, and the equipment life has been extended by 15%.
