Will dust accumulation affect the sound absorption performance of polyester fiber acoustic panels?

The key lies in the precise control of the base layer thickness. Before installation, based on the total thickness of the polyester fiber sound-absorbing panels (e.g., 12mm) and other materials (e.g., 9mm wood veneer + 3mm underlayment), leveling layers of plywood or framing at different heights should be applied to the wall surface to ensure that the finished surfaces of all materials are on the same horizontal plane. Finally, a T-shaped trim strip should be embedded at the joint for a smooth transition.

The impact is very small. High-quality UV inks or water-based penetrating inks, with a coating thickness of only 0.02-0.05mm, will only seal a very small number of micropores on the very surface, and the impact on the overall noise reduction coefficient (NRC) is negligible (usually a reduction of <0.05). However, it is crucial to avoid using paint for spraying, as paint will seal large areas of pores and severely impair the sound absorption function.

Absolutely. Through heat transfer printing or digital UV flatbed printing, any wood grain, stone grain, geometric pattern, or artistic image can be precisely replicated onto the surface of the acoustic panel. The pattern layer is extremely thin, barely affecting the original sound-absorbing porosity. Our factory offers custom design services based on provided images. Please consult our sales manager for the minimum order quantity.

The "wall-applying glue method" should be strictly used (glue is only applied to the wall substrate), not the back of the board. If glue accidentally spills, immediately wipe it gently with a damp cloth soaked in alcohol or a special cleaner. Do not wait for the glue to dry completely before scratching it off, otherwise it will damage the texture and color of the board surface.

Absolutely. Polyester fiber acoustic panels are flexible; 9mm thick panels can be safely bent into curves with a radius greater than 300mm, and for 12mm thick panels, a minimum bending radius of 500mm is recommended. During installation, it is recommended to use dry-hanging or keel fixing methods to avoid using rigid adhesives that restrict the bending stress of the panels.

The safest method is to "install first, then drill the holes." First, use a utility knife or jigsaw to roughly drill holes in the panel that are about 5mm smaller than the actual equipment. After attaching the panel to the wall, use an edge trimmer or fine-toothed saw to precisely trim along the edges of the equipment. If you are drilling the same holes in batches, it is recommended that the factory provide a pre-drilling customization service so that the panels can be directly fitted on-site, greatly improving efficiency and reducing dust.
