What is the structure and characteristics of super silent drain pipe?

In building drainage engineering, plastic pipes have gradually replaced traditional metal pipes, and to some extent, they have overcome the shortcomings of traditional metal drainage pipes, such as large water resistance, easy corrosion, large volume and easy scaling on the inner wall. However, the sound insulation performance of ordinary plastic pipes is poor. When used as a drainage pipeline, the noise of water flow in the pipeline is very loud, especially when used for indoor drainage, which will seriously damage the quiet indoor environment and affect the normal life of residents. At present, there are several large-scale production enterprises in China, such as Shanxi Gantong, Shanghai Youyi, Shanghai Baidie and Beijing Beixin. The product adopts three-layer extrusion process, the inner and outer layers are mainly made of reusable environmentally-friendly modified polypropylene resin, and the middle layer is made of special viscoelastic sound-absorbing materials. Through modification, it has good mute performance, impact resistance, chemical corrosion resistance and heat resistance.

The super mute pipe adopts a unique three-layer composite structure, and the skin layer is made of hard, tough and impact-resistant modified polypropylene, which not only protects the intermediate structure, but also ensures the good impact resistance of the pipe. The soft middle layer is made of unique viscoelastic material, which has excellent sound insulation and vibration absorption and buffering functions, and has a significant effect on reducing the noise of frequency chart 100 ~ 4000 Hz; The smooth inner layer has excellent heat resistance and chemical corrosion resistance. Environmental protection is a problem that people pay attention to at present. Noise pollution, light pollution and garbage pollution can be seen everywhere in life. Super silent drain pipe greatly reduces noise pollution and makes people's lives more comfortable. The following small series takes you to understand the super silent drain pipe and appreciate its beauty.
