Eggs, also known as cotton wave cotton, cotton peak. It is in a sound-absorbing cotton. Eggs cotton is processed through the device special form concave side of a wave-shaped sponge, which is full of small internal voids and semi-open pore structure can absorb a lot of energy incident acoustic attenuation of sound waves play a role in reducing indoor reflection sound interference and response, improve the purity of sound, is a high-performance sound-absorbing material drop bath products. Sound-absorbing cotton eggs principle: a large number of voids and bubbles inside and outside the Unicom, when the sound wave to which can cause vibrations in the air gap; the air viscous drag, air and pore wall friction, so that a considerable portion of the sound energy into heat energy It is consumed. In addition, when the air adiabatic compression, continue to occur between the air and the hole wall heat exchange, due to thermal conduction, but also make part of the sound energy into heat energy. So as to achieve the sound buffer as well as sound-absorbing effect, the size of the sound-absorbing effect with the opening of cotton as well as the entire thickness has an important relationship, too thin even sound-absorbing only a small portion of the suction, the other opening discomfort The opening is too large, it will not sound-absorbing effect, it is too little help too hard on the sound, suitable to work in this regard, absorbent cotton can also play a number of sound absorbing effect, because when the sound after absorbing too much Back to friction with sound-absorbing cotton, the original voice of the action will cushion a bit, will reduce the penetration of the original sound, and thus the noise is still there secondary effect, but the sound had to use professional noise cotton ideal . Eggs cotton Uses: The sponge non-toxic, tasteless, environmental health, is the ideal indoor noise / sound-absorbing, audio reflective material; widely used in recording studios, recording studios, video room, auditorium, drum room, KTV, Tone Room, language lab, studio, audition room, acoustics lab, conference room, studio, theaters and other occasions, interior decoration, as well as room silencers, silencers generators, speakers and other sound-absorbing silencer places. Eggs cotton Category: Fire in no fire: Fire eggs eggs cotton is divided into cotton and non-cotton fire eggs. Cotton is the addition of egg fire flame retardant standards is from the fire that interest effect. Color Classification: Fire eggs cotton generally have black and white, no eggs fire cotton can be made a variety of colors, such as red, yellow, blue, black and other colors. Thickness and density: the thickness of conventional cotton egg argument is the thickness after two peaks overlap, the thickness of leaflets usually is 3/4 the thickness of the businessmen said double sheet thickness. With the change of sound-absorbing cotton eggs thickness and density, thickness and density of the sound-absorbing effect is proportional to eggs and egg cotton cotton. Select the density of time can be selected depending on the application thickness. Eggs Cotton installation: 1, respectively, the glue evenly coated in the back and the wall of sound-absorbing cotton, and other glue eighty percent of the time, the sponge tile up, then pressed a little harder. 2, with strong double-sided adhesive sticky glue, paste on cotton, cotton pressed against the wall to press flat. 3, the direct use of a nail in the wall (note the nail head size).
