Bubble is a assembly which composed by the bubble and aluminum diaphragm , bubble's irregularities and solid makes it has many excellent properties. 1 Light Foam aluminum's densimeters is about 1/5 ~ 1/10 than pure aluminum's ,1 /20 than iron's, 1/4 than wood and plastic's . 2 High performance of sound-absorbing The features of foam aluminum's sound-absorbing are as following, the mutual interference happened when the sound into foam aluminum, and the sound energy changed into heat energy then reduce the noise.  Compared with other sound-absorbing materials, the foam aluminum's  low  frequency performance is excellent , if  the foam aluminum absorb a certain size of cavity, the sound-absorbing effect is better, and it also can be used  in a more wide frequency domain. For example:before we deal with the indoor sound-absorbing, the metope is very hard, if we coated with 10mm thick foam aluminum to reduce noise sound-absorbing, the foa... [详细介绍]
