冲孔吸音蜂窝铝板采用 “蜂窝式夹层” 结构，即以表面 涂覆耐候性极佳的装饰涂层之高强度穿孔铝板与铝蜂窝芯经 高温高压复合制造而成的复合板材。 冲孔吸音蜂窝铝板的构造结构为穿孔面板与穿孔背板， 依靠优质胶粘剂与铝蜂窝芯直接粘接成铝蜂窝夹层结构，并 且在铝蜂窝板背板贴上一层吸音无纺布。由于蜂窝铝板内的 蜂窝芯分隔成众多的封闭小室，阻止了空气流动，使声波受 到阻碍，提高了吸声系数 ( 可达到 0.9 以上 )，同时提高了 板材自身强度，使单块板材的尺寸可以做到更大，进一步加 大了设计自由度。可以根据室内声学设计，进行不同的穿孔 率设计，在一定的范围内控制组合结构的吸音系数，既达到 设计效果，又能够合理控制造价。通过控制穿孔孔径、孔距， 并可根据客户使用要求改变穿孔率，最大穿孔率＜30％，孔 径一般选用∮2.0、∮2.5、∮3.0 等规格，背板穿孔要求与面板 相同，吸音布采用德国科德宝的无纺吸音布等吸声材料。 ■ 冲孔吸音板概述 The punched sound-absorbing honeycomb alumi - num plate adopts the structure of "honeycomb sand - wich", that is, it is a composite plate made of high-strength perforated aluminum plate coated with decorative coating with excellent weather resistance and aluminum honeycomb core through high temperature and high pressure. The punched sound-absorbing honeycomb alumi - num plate has a structure of perforated panel and per - forated back plate, which is directly bonded with alumi - num honeycomb core by high-quality adhesive to form an aluminum honeycomb sandwich structure, and a layer of sound-absorbing non-woven fabric is attached to the back plate of the aluminum honeycomb plate. As the honeycomb core in the honeycomb aluminum plate is divided into numerous closed chambers, the air flow is prevented, the sound wave is hindered, the sound absorption coefficient (above 0.9) is improved, the strength of the plate itself is improved, the size of a single plate can be larger, and the design freedom is further increased. According to the indoor acoustic design, different perforation ratio design can be carried out, and the sound absorption coefficient of the com - bined structure can be controlled within a certain range, which not only achieves Generally, specifications such as 30 2.0, 30 2.5 and 30 3.0 are selected. The perfora - tion requirements of the back plate are the same as those of the panel. The sound-absorbing cloth adopts sound-absorbing materials such as non-woven sound-absorbing cloth of Germany Kedebao. > Product Overview 53 智造饰面·让城市更美丽 © ChenHang New Material
