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 foam aluminum sound-absorbing can reduce 17db noise.
3.foam aluminum's refractory performance
Foam aluminum has a good refractory performance, aluminum's fusing point is 660 degrees Celsius, foam aluminum began to soften when the temperature reaches 800 degrees Celsius.(cann't bear its dead-weight), but haven't melt. If the foam aluminum without forces.it would not be out of shape even if exposed in 780 degrees Celsius temperature, it means foam aluminum can bear higher temperature than ordinary foam aluminum which can sound-absorbing materials. In addition, foam aluminum is a non-combustible material, not like plastic materials, which produces harmful gases.
4.construction is convenient
Due to the foam aluminum is light, and it can be installed by personal people, particularly suitable for the height-work of ceiling, wall, roof etc.Due to the convenience of process, and also can be adhesived and riveted. Therefore, it's convenient to install and construct. |
