The main function of sound-absorbing panels is to absorb sound and create a quiet environment. It is a new type of building material commonly used in modern buildings. There are so many types of sound-absorbing panels on the market today that it is dizzying. According to different materials, environmental protection levels, and fire performance, it is divided into different types of sound-absorbing panels, and the application directions are also different. Below, we will introduce the types and applications of sound-absorbing panels.
According to different production materials, sound-absorbing panels are commonly found in the market, such as wood, mineral wool, fabric and polyester fiber. Wooden sound-absorbing panels are composed of veneer, core material and sound-absorbing thin felt, and are processed according to acoustic principles. They are generally divided into two types: grooved wood sound-absorbing panels and perforated wood sound-absorbing panels. The mineral wool sound-absorbing panel uses high-quality mineral wool as the base material, and is famous for its rich surface treatment forms. The surface is covered with holes of different depths, shapes and apertures. The board has a strong decorative effect, and the surface is treated with knurled mineral wool board, commonly known as "caterpillar". The core material of the fabric sound-absorbing panel is centrifugal glass wool. As an acoustic material that has been widely used all over the world for a long time, centrifugal glass wool has been proved to have excellent sound absorption performance. Many decoration companies often use such decorative materials when decorating. The raw material of polyester fiber sound-absorbing panel is polyester fiber, and the main material is made of polyester fiber, which has a good noise reduction effect and is a better sound-absorbing material.
With the improvement of people’s requirements for environmental protection standards, different sound-absorbing panels are used, and the environmental protection grades can be divided into E0, E1, and E2 grades, which are mainly classified according to the release of formaldehyde contained in the sound-absorbing panels. Among them, the E0 grade is environmentally friendly. Advanced, E1 second, E2 formaldehyde emission is relatively high. If it is directly used for indoor installation, the E1 level is qualified, which is divided into categories according to the actual production and addition of sound-absorbing panels. The fire resistance of sound-absorbing panels is also an extremely important indicator. According to national standards, it is divided into three grades: ordinary, flame retardant and fireproof, also known as A, B1, and B2 grades. The fire resistance of sound-absorbing materials required for public gathering venues such as theaters, dance halls, auditoriums, multi-purpose halls, and gymnasiums is very important, and the requirements are relatively high. The mineral wool sound-absorbing board has been tested by the National Fire Protection Testing Center for fire protection parameters. The results show that it has good fire performance, belongs to A-level non-combustible, and meets the requirements of the national standard GB8624B1. According to different materials and functions, sound-absorbing panels are widely used in places that require sound insulation and sound absorption, such as conference rooms, TV stations, studios, theaters, audio-visual rooms, opera houses, leisure and entertainment cities, hotels, multi-purpose halls, concert halls , bars, restaurants, shopping malls, schools, auditoriums, gymnasiums, KTV, etc. There are a lot of classification and application knowledge of sound-absorbing panels. Through these sharing, I hope to help you. Different sound-absorbing panels have different uses, and consumers can make more appropriate choices according to their needs.
