Perforated composite rock wool sound-absorbing board for computer room soundproofing

The moisture resistance of calcium silicate board is very good, and its stability will not expand or deform due to moisture. Its thermal insulation performance is much better than that of other ordinary brick walls. At the same time, it also has good sound insulation effect and a long service life. It is a building material with excellent performance.

Perforated calcium silicate board sound-absorbing knowledge: Fiber porous sound-absorbing board materials, such as centrifugal glass wool, rock wool, mineral wool, plant fiber spraying, etc., have a sound-absorbing mechanism where there are a large number of tiny connected pores inside the material. Sound waves can penetrate deep into the material along these pores and undergo friction with the material to reduce the conversion of sound energy. The sound absorption characteristics of porous sound-absorbing materials are that the sound absorption coefficient gradually increases with the increase of frequency, which means that low-frequency absorption is not as good as high-frequency absorption.

Perforated sound-absorbing panels form a damping system with a material cavity filled at the rear, which gradually attenuates sound consumption and achieves sound-absorbing and noise reduction effects. The perforation rate of perforated sound-absorbing panels can be adapted to absorb noise of various frequency bands, with a variety of perforation diameters and rear cavities, allowing users to "adapt to local conditions" and choose different styles of sound-absorbing panels based on the frequency of sound in different spaces.

Perforated calcium silicate board is a new type of indoor sound-absorbing board product made of calcium silicate as the substrate and perforated by punching equipment. It has excellent sound-absorbing function based on the excellent characteristics of calcium silicate board itself, and is designed specifically for open ceiling systems with both vocal and aesthetic requirements. Calcium silicate board is made of loose short fibers such as inorganic mineral fibers or cellulose fibers as reinforcement materials, with siliceous calcium materials as the main material. It is processed through pulping, molding, and accelerated curing reaction in high-temperature saturated steam to form calcium silicate cementitious material.
