Novel ultra-micropore sound-absorbing cellular board
The invention relates to the technical field of building materials, and provides a novel ultra-microporous sound-absorbing cellular board which comprises a shell, an upper plate is fixedly connected to the top of the inner side of the shell, a lower plate is fixedly connected to the bottom of the inner side of the shell, an upper nest core is fixedly connected to the bottom of the upper plate, and a lower nest core is fixedly connected to the top of the lower plate. The upper nest core and the lower nest core are arranged in a staggered mode and are in a wave shape, one side of the convex face of the lower nest core abuts against one side of the convex face of the upper nest core, one side of the concave face of the lower nest core and one side of the concave face of the upper nest core form a cavity, and an upper micro hole is formed in the position, located in the center of the cavity, of the interior of the upper plate. The novel ultra-microporous sound-absorbing cellular board provided by the invention has good sound-absorbing performance and can effectively absorb sound wave energy, so that the numerical value of the sound-absorbing coefficient is 0.85, and the styles are more diversified by adopting different outer-layer materials, aperture sizes and sound-absorbing materials.
本发明涉及建筑建材技术领域，提供一种新型超微孔吸音蜂窝板，包括外壳，所述外壳内侧的顶部固定连接有上板，所述外壳内侧的底部固定连接有下板，所述上板的底部固定连接有上窝芯，所述下板的顶部固定连接有下窝芯，所述上窝芯和下窝芯交错设置且均为设置为波浪形，所述下窝芯凸面的一侧与上窝芯凸面的一侧相抵触，所述下窝芯凹面的一侧与上窝芯凹面的一侧形成一个空腔，所述上板的内部位于空腔的中心处设置有上微孔。本发明提供的一种新型超微孔吸音蜂窝板具有良好的吸音性能，可以有效地吸收声波能量，使得其吸音系数的数值为0.85，以及采用不同外层材质、孔径大小以及吸音材料的选用，使得款式更加的多样化。
