Brushed Aluminium Honeycomb Roof Panel with Edge Sealed for Train Compartment Roof

Product Description

Brushed Aluminium Honeycomb Roof Panel with Edge Sealed for Train Compartment Roof is the surface plates brushed to make better metal quality. The edges are sealed with glue or aluminum rectangular hollow section. The finished products are generally used on the compartment roof use.

1. Aluminum honeycomb panel, as an important lightweight material, is widely used in aviation manufacturing industry. It also has been used for the foreign railway vehicle and is being used more and more widely, such as the French TGV series, Italy ETR series high-speed train. Only in recent years it is begun to be used domestic industry.

2. French TGV series and ETR series of high-speed train in Italy have been using the aluminum honeycomb sandwich composite panels for inner wall and roof. Later, many European railway vehicle manufacturing enterprises adopted the aluminum honeycomb panel for producing spare parts for the railway vehicle within the scope of application on side wall, ceiling, partition board, floor, door plank and rack components inside and outside the door. Among the above, Italy was leading the aspect of the application of aluminum honeycomb panel and they have already begun to manufacturing the complex shape of rack and medial wall panel with curved window with aluminum honeycomb panel.

3. For the domestic point, the earliest application of the aluminum honeycomb board is to make the inter-compartment of the 25A soft sleeper. At the end of the 20th century, because of the higher requirement on the lightweight train, aluminum honeycomb panel was applied to make the partition, ceiling panel and door plank with good performance. Then, the aluminum honeycomb panel was widely used not only to make the partition, flat-top board, lower equipment tank bottom and various door panels, also make air-conditioning duct and air conditioning unit dome in which compartment wall, ceiling board, air conditioning duct and air conditioning unit dome are with best effect, greatly reducing the weight of the related parts and components, achieving the overall vehicle light weighting, and improving the precision and quality of parts and components manufacturing, thus improving the manufacturing quality of the vehicle. However, the real breakthrough in the application of the aluminum honeycomb panel is the CRH series.

General Description

Aluminum honeycomb panel is a bonded sandwich structure system of two surface aluminium plates and one honeycomb cores with a special purpose adhesive. Industrial used aluminium honeycomb panel will add some more processes such as surface treatment, edging, embedding, carving and so on to make the panel suitable for special conditions. It has been widely used by the industries of civil construction, transportation, exhibition, signage, elevator, clean room etc. The honeycomb technology is from aerospace technology. The whole production process is finished in the modern factory, using hot pressing or vacuum pressing technology. Due to the high thermal conductivity between the aluminum plates and honeycomb, it is synchronized the thermal expansion and contraction of the inside and outside aluminium material. There are small holes on the honeycomb core foil wall so that the air is free of flowing inside the panel box. Furthermore, sliding mounting buckle system does not cause structural deformation during thermal expansion and contraction.

Features

The center material is aluminum hexagonal honeycomb with a small density (about 3 to 7 kg per square meter), about 1/5 of the weight of wood with the same area and thickness, 1/6 of the glass, 1/7 of solid aluminium, which greatly reduced the building load and construction cost. Thanks to the air contained in the core, the panel can be sound and thermal insulated. Because of no combustible material contained, the fire rating can be at least B1 level. The panel performs well also on waterproof, moisture-proof, no harmful gas release, with a high unit mass of the specific strength and stiffness, not easy to deformation, completely overcoming the collapse and deformation in the center area if with large panel. The panel edge can be cut depending on real conditions. The PVDF coating can guarantee the product life more than 30 years.

After surface treated with corrosion resistant fluorocarbon resin, it can be widely used on curtain wall, roof, large façade, signs and interior decoration. The front plate of the aluminum honeycomb panel is painted with E. C. C. A. quality standards PVDF fluorocarbon paint with ordinary color or metallic color, so the surface has excellent weather resistance.

In case of heavy rain, there is particularly large noise when the raindrops hit the aluminum veneer or aluminum-plastic panel, while honeycomb panel can avoid this situation. Aluminum honeycomb panels are generally made of fluorocarbon coated aluminum plates. The continuous roller coating with PVDF material is the most important point to avoid color difference and flat coating film. Based on this, it can keep the exterior building with bright color for long time.
