Description

Technical Field

[0001] This utility model relates to the field of sound-absorbing panel technology, specifically to a novel keel-structured sound-absorbing panel and sound-absorbing components. Background Technology

[0002] Medium-density fiberboard (MDF) is a type of fiberboard made from wood fibers or other plant fibers. It is produced through a process of fiber preparation, application of synthetic resin, and pressing under heat and pressure. Based on its density, it can be classified into high-density fiberboard (HDF), medium-density fiberboard (MDF), and low-density fiberboard (LDF). Due to its uniform structure, fine texture, stable performance, impact resistance, and ease of processing, MDF is widely used in furniture, decoration, musical instruments, and packaging in China. It is mainly used for engineered wood flooring, door panels, partitions, and furniture. In home decoration, MDF is primarily used for surface treatment in mixed-paint processes. Medium-density fiberboard is generally used for furniture making because high-density fiberboard is too dense and prone to cracking, making it unsuitable for furniture. High-density fiberboard is generally used for interior and exterior decoration, office and residential furniture, audio equipment, vehicle interior trim, and can also be used as a material for anti-static flooring in computer rooms, wall panels, security doors, partitions, etc. It is also a good packaging material. In the future, it will be used as a base material for engineered wood flooring, etc.

[0003] Currently, the traditional production method for MDF (medium-density fiberboard) strips involves cutting a solid MDF sheet into strips and then processing them. This solid structure of MDF strips results in high material consumption and higher material costs. Furthermore, its solid shape and weight increase the difficulty and cost of transportation and installation. In addition, the solid structure has poor sound absorption performance, failing to meet the needs of some scenarios with specific sound absorption requirements, thus limiting its application in related fields.
