Engineering Introduction:  

In order to reduce the impact of the noise produced by high-speed vehicles on both sides of the highway and the public places of culture and education, this project uses acrylic and ultramicro perforated aluminum plates to absorb sound insulation barrier. The sound insulation barrier plate is of light quality, easy to install and free from pollution. The production quality of the factory line is controllable and the color is rich. It can be recycled two times and is convenient for maintenance. Acoustic components can be processed into several kinds of suction and sound insulation acoustic units, such as shutter window type, perforated type, micro perforation type and slotted hole type, and sound insulation barrier is set up. The acoustic baffle between the noise source and the protected area is used to prevent the sound source from spreading to the direct sound of the receiving point, and to make the diffraction sound as small as possible, so that the equipment, buildings and environmental places in the sound film area are protected.      

Product material:    

Metal: aluminum plate, galvanized plate, color steel plate, etc.            

● Non metals: FRP, (transparent material):pc endurance board, laminated glass, acrylic board, sun board, etc.            

● Hole type: blinds and microperforation            

● Surface treatment: high voltage electrostatic spraying (spraying all kinds of colors according to needs).  

Product features:            

1.The sound insulation is large: the average sound insulation amount 37dB            

2.The sound absorption coefficient is high: the average sound absorption coefficient is 0.85

3.weathering durability: the product has the characteristics of water resistance, heat resistance, UV resistance and so on. It will not cause poor performance or abnormal quality due to the change of rainwater temperature.            

4. beautiful appearance: you can choose a combination of colors and shapes to coordinate with the surrounding environment and form a beautiful landscape.
