Melamine foam material itself is flame retardant, high temperature stability and flexibility. The product has unique sound absorption, heat insulation, flame retardant, high temperature resistance, light weight and other comprehensive properties. Its mesh length to diameter ratio is L/D between 10 and 20, and its extremely high opening ratio characteristics ( 8kg/M3 density melamine foam has an opening ratio of more than 97%), so that the sound wave can be easily and efficiently entered into the deep layer of the foam and converted into a mesh. The vibration energy can be consumed and absorbed, and the reflection can be effectively eliminated. especially for low frequency noise.
Melamine foam has excellent sound absorption performance and good fire resistance. It is applied to air conditioning equipment and ventilation system circulating fan sheet to reduce noise. The inner wall of the central air conditioner and the fan cover can also be installed melamine resin foam to reduce the noise level. Its low thermal conductivity and high temperature resistance have become key factors in its application to solar collectors.
Melamine foam can withstand high temperature (long-term working temperature is about 150 ° C, short-term peak temperature can reach 200 ° C); It can withstand low temperature capacity (long-term working temperature is about -150 ° C, short-term peak temperature can reach - 180 ° C) and flame retardant, making it suitable for more technically demanding work. Through the shape mechanical cutting, melamine foam can be processed into insulation layer material for pipeline protection. While providing insulation, energy losses are controlled, maintenance is simplified, and noise levels are reduced.
Features: hot pressing, high strength, cutting and compounding other materials;
Applicationg:
1. The use of nano-foam in at home air conditioners can reduce air conditioning noise;
2. Central air-conditioning ventilation ducts use melamine foam to reduce air conditioning noise.
