In Power Station applications, melamine resin foam has excellent sound absorption properties, and maintains stable structure and performance under high temperature and high humidity conditions, and does not contain any dust, halogenated hydrocarbons, flame retardants and Toxic heavy metals, is especially suitable for the improvement of air inlet acoustics and wind speed regulation in thermal power stations, noise reduction and heat insulation materials for wind power generation, and overall acoustic insulation in hydropower stations. It is the best material to replace traditional glass wool.

Acoustics insulation in the main plant of the Thermal Power plant (noise in the main plant area, noise from the auxiliary turbine of the turbine, the noise of the turbine itself, the exhaust port of the exciter, the oil cooler of the main engine, the water level adjustment station of the deaerator, the intermediate water pump unit, various steam pipelines, Vacuum pump units and other equipment mixed noise), cooling tower heat and acoustic insulation and, circulating water pump noise reduction, induced draft fan acoustic improvement and noise reduction, boiler and ancillary equipment heat insulation and noise reduction.

For Wind Power noise sources, one is aerodynamic noise, which is generated by the cutting of the air by the blades of the generator/turbine as it turns, making a sound similar to “humming”; the other is mechanical noise and structure noise, mechanically related. The high-efficiency sound-absorbing and damping material for wind power plants developed by SINOYQX uses a composite damping sheet of medium-and high-frequency sound-absorbing melamine foam on the inner wall of the engine room to effectively absorb, reduce and block vibration to solve self-mechanical noise and structural noise and vibration, so as to achieve the effect of noise reduction and shielding radiation, and the excellent thermal insulation performance of melamine foam (thermal conductivity, 0.035 W/ (m*K)) ensures that the wind equipment maintains a relatively stable working temperature in various working conditions in safe and stable long-term operation.

The main sources of noise in Hydropower Generation are the rotation of the large shaft of the turbine, the rotation of the upper generator wind tunnel rotor, and the impact of the water flow in the lower runner chamber against the flow channel. The medium and high frequency sound absorption performance (0.95NRC) is especially suitable for the noise reduction and sound absorption treatment of the hydropower studio.

SINOYQX is a GE (General Electric) global certified melamine resin foam supplier, and has supplied GE’s global power station projects.
