Gradient absorbing cotton insulation materials used in polyester fiber is natural, the main material used in polyester
fiber and other environmentally friendly materials, production processes to import certain degree of particularity, so as
to form a ladder-like structure density ingenious full-frequency sound absorption. When will it melt blown fiber raw
materials, and intertwined into a three dimensional structure of the fibers, there is a very slight gap between them.
Sound-absorbing cotton gradient field drama theater in general, KTV, recording studio and other places, at the same time
replace the glass wool and rock wool interval between use for lightweight wall.
Healthy green absorbing material main advantages are: environmental protection, high strength, waterproof, moisture
-proof, odorless, non-formaldehyde, advanced processing technology and longer life; not perishable, some fungi, salt
corrosion or other chemical substances have a strong the resistance; process does not add any adhesives; one hundred
percent recyclable do, is absolutely one material of environmental protection.
????Many people think that sound-absorbing cotton and cotton insulation is a material, in fact, there is a difference.
Cotton insulation insulation principle is: When the sound vibration, sound waves pass through the air and the sound
structure of cotton fiber, superimposing sound waves collide with each other and through the noise cotton fibers reflected
acoustic energy into heat energy and thus weaken the acoustic intensity and finally the sound disappears. Cotton
insulation primary role: good water resistance, sound insulation, metal fatigue can effectively reduce the car chassis,
but also play the role of insulation, surface paint on the hood play a protective role.
