Sound insulation principle of aluminum honeycomb panel

　　aluminum honeycomb panel采用热压成型工艺加工，其导热系数高，对铝板和窝芯的热胀冷缩，以及铝板上的微孔，使aluminum honeycomb panel内的空气得以自由流动，作为一种新型建筑材料，越来越受到市场的关注。aluminum honeycomb panelIt is a kind of aluminum veneer. The sound insulation effect of aluminum honeycomb panel is very good. Do you know why?

The structure of 1. aluminum honeycomb panel is very special, it is composed of PVDF fluorocarbon coated aluminum panel, honeycomb aluminum core, special high viscosity adhesive and polyester aluminum base. The aluminum perforated plate and the compact honeycomb structure improve the sound absorption performance of the honeycomb aluminum plate to a certain extent.

2. design In engineering, aluminum honeycomb panels with different perforation rates can be designed and processed according to needs to obtain different sound absorption effects. Because of its high stiffness, aluminum alloy honeycomb panel is not easy to be stimulated by vibration in the sound field (only about 1/6 of aluminum veneer), so it can reduce the sound pollution caused by resonance. The test shows that the 25mm thick honeycomb aluminum sheet can reduce the noise of 21dB.

Suitable for buildings, can withstand high wind pressure, meet the requirements of large grid, and have good flatness. The application of aluminum honeycomb panels is very extensive. It was originally used in the aviation industry and is now used in the construction and decoration industries, such as building curtain walls, exterior wall panels, interior walls and ceilings, canopies, partitions, etc. In addition, it can also be used for the interior of rail transit vehicles, ship interior, elevator decoration, bus shelters, display stands, electronic whiteboards, etc.
