What are the requirements for the raw materials of aluminum honeycomb panels

1Aluminum decorative panel

aluminum honeycomb panel装饰面板的材质一般选用3003、5005Equal grade, low alloy composition1100The plate is less used. The decorative surface is sprayed or rolled, and the coating is polyester or fluorocarbon paint. The exterior wall panel is preferably sprayed, and more than three coats are required. The thickness of the paint layer≥40μmThis ensures the durability of the coating.

铝板在涂漆前需经过严格的表面阳极化处理，以保证足够的涂层附着力和与蜂窝芯的粘接强度，面板涂层应满足国家规范YS/T429.2-2000requirements.

2Aluminum back plate

The aluminum honeycomb panel backplane should be made of the same material as the panel. The surface should be anodized. The side exposed to the air should be coated with a protective coating. The coating materials can be polyester, epoxy, acrylic and other materials to prevent long-term exposure to the air and cause corrosion of the aluminum plate.

3Aluminum Honeycomb Core

Aluminum honeycomb core material is made of aluminum foil and special honeycomb node adhesive on the aluminum honeycomb core production line. The factors that affect the performance of honeycomb core mainly include aluminum foil, node adhesive and honeycomb core specifications and other parameters.

3.1 Aluminum Foil

Aluminum Foil应选用3003Brand, the processing process should be strictly surface treatment, in the strength or durability requirements of the product, should be used with caution.1100Honeycomb core material manufactured by pure aluminum foil processing.

3.2 node glue

Epoxy modified high-temperature curing adhesive should be selected for node glue, which not only provides sufficient bonding strength but also has excellent environmental resistance and high and low temperature resistance. The general adhesive is often easy to make the honeycomb core degumming due to low strength, resulting in overall damage and instability.

蜂窝芯的节点强度是评价其性能的主要依据，其节点强度数据应≥2.0N/mm。

3.3 Honeycomb core specification

Aluminum honeycomb core specifications are determined by the thickness of aluminum foil and honeycomb cell size. Different specifications of aluminum honeycomb have different densities and different mechanical properties, and their cost also varies greatly.

Honeycomb core specification可以用蜂窝孔格内切圆直径(imperial units)and aluminum foil thickness/Side length of hole lattice(Metric Units)Two ways of expression, China's national standard is based on the thickness of aluminum foil/Kong Ge side length to express.
