Process characteristics of honeycomb aluminum plate

aluminum honeycomb panelAs an important lightweight material is widely used in the aviation manufacturing industry, in foreign railway vehicles also have early application, its use is quite extensive, the domestic only in recent years began to use aluminum honeycomb panel, although it has achieved certain results, its scope of application is still very limited, the characteristics of honeycomb sandwich material and the scope of application of understanding needs to be further strengthened and expanded.

Aluminum honeycomb panel is a composite material bonded by aluminum honeycomb core material and surface material. In summary, aluminum honeycomb panel has the following basic characteristics:

(1)Light weight, high specific strength, especially high bending stiffness, the same quality of aluminum honeycomb panel bending stiffness of about aluminum alloy5Times.

(2)It has extremely high surface flatness and high temperature stability, easy to form and not easy to deform. Aluminum honeycomb panels can not only be made into flat panels, but also can be made into hyperbolic and single panels, which are easy to disassemble and assemble after being made into vehicle parts.

(3)Excellent corrosion resistance, insulation and environmental adaptability, can adapt to the railway EMU and passenger car a variety of harsh operating environment;In addition, according to the need, this kind of plate can be used surface paint or surface paste fireproof board treatment, to achieve good decorative, fire resistance.

(4)Unique resilience, can absorb vibration energy, with good sound insulation and noise reduction effect.

(5)High fire rating, meet international intermodal fire protection standardsUIC564-2-199lRegulations on fire prevention and fire fighting for railway passenger cars or similar vehicles for international intermodal transportAlevel requirements.

(6)The smoke density after fire meets the high-grade international railway fire protection standards and has good self-extinguishing properties.;The heat release value is low, can form a refractory layer, can reduce the release of smoke and toxic gases, has excellent environmental performance.

(7)Excellent molding and manufacturing process, can meet the railway vehicle interior parts complex shape, high stability requirements.

Aluminum honeycomb panel is a high-grade aluminum alloy panel, back plate and aluminum honeycomb core material hot pressing composite molding of large surface composite materials, product specifications are diverse, the surface can be embossed, mirror, relief, drawing, electroplating, anodizing, matte, bright light and metal color and other treatments, to meet the application needs of a variety of places.

对于单曲面造型的室内aluminum honeycomb panel幕墙装饰，如何解决过去传统的铝板加工、铝板安装的弊端，扬长避短呢?At present, the more popular and fashionable decorative hanging process is to use a mold to form aluminum honeycomb panels, the inner and outer arcs are perpendicular to the installation surface, the dense seam splicing is installed, the corner code is unilaterally locked, and the other side is misplaced and firmly inserted. The installation method can achieve the effect of straight, smooth, beautiful and generous lines, and realize the real effect of circular arc-shaped aluminum panels, which is much more beautiful than the assembly effect of small flat glass folding lines.;It is a new product that replaces the traditional practice of the past. The system uses a number of single-surface arc-shaped aluminum plates formed by mold processing, and then welded and installed, which increases the smooth and beautiful lines compared with the assembly of small flat broken lines. It also reduces the stress concentration during material installation and keeps the finished product installed without deformation. At the same time, the angle code is staggered and inserted into the lock buckle, which can solve the effect of tight seam assembly.
