Insulation and noise reduction of household appliances

The compressors of refrigerators and electric freezers are noisy, especially when the night is quiet. Joylenge™ melamine foam can be used for compressor noise reduction, which is the same as air conditioner compressor noise reduction. The noise of the vacuum cleaner is very large, especially for large vacuum cleaners, and the noise is unbearable. Joylenge™ melamine foam can be used for noise reduction of vacuum cleaners, especially for large vacuum cleaners with small boilers. Joylenge™ melamine foam can wrap small boilers and completely absorb the noise generated by the boiler even if the boiler temperature exceeds water. The boiling point, Joylenge™ melamine foam is still not aging decomposition, can maintain good sound absorption and noise reduction for a long time. The insulation layer of the water heater generally uses polystyrene, but the working temperature of polystyrene is too low to meet the requirement that the water temperature stay near the boiling point for a long time. Joylenge™ melamine foam has been used in high-end water heaters.
