Perforated sound absorbing plate based on bamboo plywood and preparation method thereof
The invention discloses a perforated sound absorbing plate based on a bamboo plywood and a preparation method thereof. The preparation method of the perforated sound absorbing plate based on the bamboo plywood comprises the following steps of shaping, slat weaving, drying, adhesive applying, blank preparation, hot pressing, edge cutting, and perforating. The perforated sound absorbing plate based on the bamboo plywood has the advantages that the sound absorbing plate is processed and manufactured by bamboo slats and bamboo wires, and the pores in the bamboo can be utilized to improve the absorbing of sound waves; the bamboo slats and the bamboo wires are longitudinally and transversely staggered and arranged to improve the strength of the bamboo plywood; when the bamboo wires are perforated, the bamboo wires are easily cracked to generate burrs, and the friction between an air column at a hole neck and the hole wall is improved; a truncated frustum-shaped small hole with a large interior and a small exterior is perforated, so the friction effect is improved, and the sound absorbing effect of the perforated sound absorbing plate is improved.
