Calcium Silicate Perforated Sound-absorbing Board

Perforated sound-absorbing series board is the use of calcium silicate board or medium density fiber cement board as the substrate, after professional punching equipment process, perforation into the new indoor sound-absorbing products, calcium silicate board itself has excellent characteristics, with excellent sound absorption function, designed for both sound absorption requirements, and beautiful requirements of the building sound absorption system and design. Perforated calcium silicate board has a variety of hole styles and aperture. The principle of sound absorption is that there are a large number of tiny connected pores inside the material, and the sound waves can penetrate into the interior of the material along the pores, and friction with the material to convert sound energy into heat energy, so as to achieve the effect of sound absorption and noise reduction. Perforated calcium silicate board through precise perforated design, so that the sound absorbing board in the low channel to the audio have super sound absorbing performance, for high audio, can be a layer of non-woven sound-absorbing material can be pasted on the back of the perforation sound absorbing board, such as non-woven sound absorbing cloth or other damping sound absorbing material. In addition to a variety of places perforated sound absorption series ceiling, at the same time can be used as a sound absorbing wall board with sound absorption requirements environment. It is also a new type of building and industrial plate with excellent performance, its products fire-proof, moisture-proof, sound proof, moth-proof, good durability, is a modern ideal type of decorative plate.
