Learn more about the structure of the lower honeycomb aluminum plate

Honeycomb aluminum plate is a composite plate composed of high-strength alloy aluminum plate surface, bottom plate and aluminum honeycomb core. It adopts high temperature and high pressure honeycomb sandwich structure, which is light in weight and high in strength. It has the characteristics of good rigidity, strong corrosion resistance and stable performance. The air layer between the surface and the floor is divided into several closed holes by the honeycomb, which greatly restricts the propagation of thermal and acoustic waves. Compared with other curtain wall decoration materials, honeycomb aluminum panels have good warmth retention and warmth retention. Insulation performance. The honeycomb aluminum plate is all made of aluminum, and the surface, bottom plate and core material are all made of high-strength aluminum alloy. It is an environmentally friendly and environmentally friendly product, easy to recycle, and an environmentally friendly product. New product development direction. Building materials of the future.

Structure of Honeycomb Aluminum Plate

According to the construction industry standard JG / T 334-2012 Building Exterior Wall Honeycomb Aluminum Composite Panel, the raw materials required for the production of honeycomb aluminum panels were selected, and the company\'s material selection was formulated.

Aluminum decorative panel

Honeycomb aluminum decorative panels are usually made of aluminum plates (such as 3003, 5005, etc.), and 1100 panels with low alloy components are rarely used. The decorative surface is sprayed or rolled, and the coating is polyester or fluorocarbon paint. Curtain wall plate is a roller coating, need more than 3 kinds of coating, coating layer thickness ≥ 32μm. .

The aluminum plate must undergo strict surface anodizing treatment before painting to ensure sufficient coating adhesion and adhesion strength to the honeycomb core. Panel coatings must comply with national standards YS/ T429.2-2000 requirements.

Honeycomb aluminum backplane shall be made of the same material as the panel, and the surface shall be anodized. Surfaces exposed to air must be coated with a protective coating. The coating can be polyester, epoxy, acrylic, etc. Exposure to air for a long time will corrode the aluminum plate.

honeycomb core material

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

Aluminum Foil

The aluminum foil shall be 3003 grade aluminum foil, and the surface treatment shall be strictly carried out during processing. Products that require strength or durability should be careful to use honeycomb core aluminum ground from 1100 pure aluminum foil.

node glue

The adhesive adhesive should not only provide sufficient adhesive strength, but also use an epoxy-modified high-temperature curing adhesive with good environmental resistance and high-low temperature properties. Because common adhesives have low strength, they tend to debond the honeycomb core, resulting in overall damage and instability.

The node strength of the honeycomb core is the main criterion for evaluating performance, and the node strength data should be ≥ 2.0N/ mm.

Honeycomb core specification

The specifications of the aluminum honeycomb core depend on the thickness of the aluminum foil and the size of the honeycomb unit. Depending on the specifications, density and mechanical properties of the aluminum honeycomb, the cost is also very different.

Honeycomb core specifications can be expressed in two ways: the diameter of the inscribed circle of the honeycomb hole (in inches) and the length of the aluminum foil/hole side (in meters). The national standard of our country is expressed in thickness. Side length of aluminum foil/battery.
