The cellular aperture of amount, these apertures can absorb the propagation energy of sound wave, prevent the further propagation or reflection of sound wave,
Aluminosilicate fiber material after final cooling substantially increases sound absorption, the soundproof effect of material due to the presence of these cellular apertures
And effectiveness.The technical scheme takes the method for natural cooling to be molded aluminum fiber using the method being meltblown, but
In actual production process, violent oxidation reaction occurs after being contacted with oxygen in air for the aluminium wire that is meltblown out, and because aluminium is fine
The diameter of dimension is smaller, it is easy to will oxidation scission, cause yield rate to be greatly reduced, have much room for improvement.
