Punched sound-absorbing sandwich panel, also known as paper faced gypsum punched panel, is a lightweight building sheet made from gypsum as the main raw material, mixed with appropriate amounts of fibers, starch, accelerators, foaming agents, and water. Its holes are punched by specialized equipment.
What are the characteristics of perforated soundproof sandwich panels? Let's take a look below.
1. Using perforated sound-absorbing sandwich panels as partition walls weighs only 1/15 of the same thickness brick wall and 1/10 of the block wall, which is beneficial for structural seismic resistance and can effectively reduce the cost of foundation and structural main body.
2. Punched sound-absorbing sandwich panels have about 60% of tiny pores, which have good lightweight insulation performance due to the low thermal conductivity of air.
3. Due to the non flammability of gypsum core itself and the absorption of a large amount of heat during the release of chemical water when exposed to fire, the rise in ambient temperature is delayed. Therefore, perforated sound-absorbing panels have good fire and flame retardant properties.
4. Punched sound-absorbing sandwich panels are made of a single lightweight material, such as aerated concrete, expanded perlite board, etc. The single-layer wall can only meet the sound insulation requirements when its thickness is large, while the paper faced gypsum board partition wall has a unique cavity structure and good sound insulation performance.
5. The perforated sound-absorbing sandwich panel has a smooth surface, and seamless surfaces are formed between panels through seam treatment. The surface can be directly decorated.
6. Good Constructability: Punched sound-absorbing sandwich panels have the properties of being nailable, planing, sawing, and adhesive. They are used for indoor decoration and can achieve ideal decorative effects. With just a cutting knife, paper faced gypsum boards can be easily cut, making construction very convenient. Using them as decorative materials can greatly improve construction efficiency.
7. Using perforated sound-absorbing panels as the wall, the minimum thickness of the wall can reach 74mm, and it can ensure the sound insulation and fire resistance performance of the wall.
8. The perforated sound-absorbing sandwich panel is made of natural gypsum and paper surface as raw materials, and does not contain asbestos that is harmful to the human body (the vast majority of calcium silicate boards and cement fiber boards use asbestos as a reinforcing material for the board).
Punched sound-absorbing sandwich panel is an ideal sound-absorbing material. Galvanized punched sound-absorbing panels are widely used in the modern decoration industry, playing a role in sound-absorbing, environmental protection, flame retardant, thermal insulation, heat preservation, lightweight, easy dust removal, cutting, fast construction, and long service life.
Punched sound-absorbing sandwich panels are used for sound-absorbing textile factories and noise exceeding standard factories in music halls, theaters, recording studios, studios, conference rooms, sports halls, exhibition halls, dance halls, KTV private rooms, home film and television halls, factories, soundproof rooms, courts, lecture halls, interrogation rooms and other acoustic venues, as well as sound-absorbing wall panels and ceiling panels in large public buildings.
