What is a perforated sound-absorbing board?
Huacheng Xing perforated calcium silicate board is the use of calcium silicate plate as the substrate
, through professional punching process equipment, punch and become a new type of indoor sound-absorbing products, calcium silicate board itself has excellent features, with excellent sound-absorbing function, designed for both the acoustic requirements, and with the requirements of the building sound absorption system is designed. The perforated calcium silicate plate has a variety of patterns and sizes of holes. The principle of sound absorption is that there are a large number of tiny connected pores inside the material. Sound waves can go deep into the interior of the material along the pores. The perforated calcium silicate plate is designed through precise perforation, so that the sound-absorbing plate has super sound-absorbing performance in low to medium audio frequency. For high audio frequency,A layer of non-woven sound-absorbing material, such as non-woven sound-absorbing cloth or other damping sound-absorbing material, can be pasted on the back of the perforated sound-absorbing board. In addition to various places perforated sound-absorbing series ceiling, at the same time can be used as a sound-absorbing environment sound-absorbing wallboard.It is also a new type of building and industrial plate with excellent performance. Its products are fireproof, moisture-proof, soundproof, moth-proof and durable. It is a kind of modern ideal decorative plate.
7. Long service life: huacheng xing perforated sound-absorbing series plate has stable performance, acid and alkali resistance, insect resistance and other characteristics, which can ensure the use of ultra-long
