1. Introduction to polyester fiber sound-absorbing decorative panels
Polyester fiber sound-absorbing panels have the functions of sound absorption, muteness, noise reduction, and flame retardancy. The material is uniform and solid. It is not only elastic, tough, wear-resistant, It is impact-resistant and not easy to scratch. The thin plate resonance sound absorber formed by it and the cavity has excellent effect. It is a high-efficiency sound-absorbing material with a wide frequency band. In addition, polyester fiber sound-absorbing decorative boards are light in weight and have excellent material properties. Unlike some brittle materials such as perforated gypsum boards and cement fiber pressurized boards, which produce fragments or fragments, there is a danger of falling, and the formaldehyde/formaldehyde emission level is far from the standard. The formaldehyde emission is less than or equal to the national standard. It is a new acoustic material that replaces the previous laminates plus sponge or glass fiber. It is easy to destroy, does not pollute the environment, and can be recycled.
The sound-absorbing principle of polyester fiber board is that there are a large number of tiny connected pores inside the material. Sound waves can penetrate deep into the material along these pores, causing friction with the material to convert sound energy into heat energy. It is a porous sound-absorbing material. The sound absorption characteristic is that the sound absorption coefficient gradually increases as the frequency increases, which means that low-frequency absorption is not as good as high-frequency absorption.
The necessary condition for sound absorption of porous materials is that the material has a large number of voids, the voids are connected to each other, and the pores penetrate deep into the material. One of the misunderstandings is that materials with rough surfaces have sound-absorbing properties. In fact, this is not the case. For example, roughened cement and stone with convex and concave surfaces basically have no sound-absorbing properties. The second misunderstanding is that materials with a large number of holes inside the material, such as polystyrene, polyethylene, closed-cell polyurethane, etc., have good sound absorption properties. In fact, these materials have no connectivity inside the holes, so sound waves cannot penetrate deeply. There is vibration and friction inside the material, so the sound absorption coefficient is very small. The sound absorption mechanism of the sound absorber structure composed of polyester fiber board and cavity body is thin plate resonance sound absorption. At the resonant frequency, a large amount of sound energy is absorbed due to the violent vibration of the thin plate. It has good sound absorption performance for medium, high and low frequencies.
Cleaning problems: Use a vacuum cleaner to clean dust and other adherents. Small areas can be wiped with detergent when applying liquid. Large areas can only be removed by replacing the board.

2. Construction prerequisites
Before construction, pay attention to board selection and arrangement to avoid slight color differences
Polyester fiber sound-absorbing panels are made of polyester fiber. The raw materials are hot-pressed and formed. Due to the different production batch numbers of the colored yarns, slight color differences are likely to occur under the action of light. Therefore, when purchasing, try to use polyester fiber sound-absorbing panels produced with the same batch number. Before construction, the polyester fiber sound-absorbing panels will be used. Arrange the boards, adjust the color difference and then install according to the adjusted arrangement sequence (it is best to wear gloves to avoid contamination).
It is advisable to use a steel ruler when cutting the board surface
During construction, polyester fiber sound-absorbing panels need to be cut. It is recommended to use a steel ruler or alloy square steel as a ruler when cutting (do not use wooden strips or soft material as a ruler) to avoid excessively large or distorted splicing gaps caused by uneven cutting lines.
In order to relatively reduce the splicing gap, the blade can be appropriately tilted inward during cutting, so that the interface surface forms a bevel, which makes it easier for the panels to join during construction and reduces the gap.
For blades used for cutting or chamfering, it is recommended to use imported blades
Due to the quality of the steel of domestic utility blades, the blades are not sharp enough and have a short service life. They are prone to burrs and rough surfaces when cutting or chamfering. Especially when chamfering, the rough surface is obvious, so it is best to use high-quality imported blades.
For beveling, you can use the special beveling plane for this product.
, Base surface treatment
The base surface needs to be flat. When pasting directly on the cement base surface, the base surface should be smoothed first, and then the polyester fiber sound-absorbing board should be pasted. If there is a back cavity, For the base layer, the gaps between the plywood splicing should first be pasted with tape (or tape). If there is a perforated board base layer, the holes should be processed before the perforated board is installed (filming on the inside can be used). To avoid stains caused by air flow under the base layer.
, Selection of glue for pasting
First consider using glue that meets national environmental protection requirements.
Different types of adhesives can be used according to different pasting base surfaces.
[] For cement or wooden bases, you can choose benzene-free universal glue or white latex made of neoprene rubber.
[] On the premise that the gypsum board base surface is not susceptible to moisture, white latex or cellulose-based wallpaper glue can be used (it should be fixed with pattern nails immediately after applying the glue to prevent the glue from being damaged). If the board surface is easy to move or may get damp, you can use universal glue.
Polyester fiber sound-absorbing board is a porous board that can easily absorb glue and block holes. It is recommended to apply glue on one side during construction ( Only apply glue on the wall, and the amount of glue applied is slightly thicker than normal). At the same time, it can also be reinforced with pattern nails.
, Yin and Yang corners
Polyester fiber sound-absorbing panels can be used as Yin and Yang Corner treatment, the method is the same as the construction method of aluminum-plastic panels.
3. Application scope
Polyester fiber sound-absorbing decorative panels can be used in home theaters, hotels, dance halls, nightclubs, boxes, concert halls, multi-functional Halls, studios, recording studios, theaters, offices, conference rooms, indoor gymnasiums, libraries, exhibition halls, classrooms, training centers, interrogation rooms and other indoor places.
