How about the quality of aluminum honeycomb

　　how about the quality of aluminum honeycomb:Natural stone honeycomb aluminum sheet is a new type of composite material with sandwich structure, which is composed of two layers of aluminum sheet and aluminum honeycomb core through adhesive. The panel of honeycomb aluminum plate is usually sprayed with fluorocarbon coating or polyester coating. The fluorocarbon coating is widely used outdoors because of its good weather resistance and self-cleaning, and the polyester coating is mostly used indoors.Stone Honeycomb PanelIt can be made into a board with lighter weight, high strength, good rigidity and very flat surface, which can be used for structure, cushion, partition and decoration, such as curtain wall, building partition, sound-absorbing board, high-speed train, ship, car carriage, etc.

Determination of the bending stiffness of the whole plate:

a) Test method: According to Test Method for Bending Properties of Sandwich Structures (GB/T) 1456-2005) The three-point bending method of the extended beam specified, measured the maximum load P and the bending stiffness D of the whole board when the stone panel of the stone honeycomb board cracks or breaks;

B) Calculation method: Appendix A Stiffness Calculation of Stone Honeycomb Composite Board of the Code for Curtain Walls of Artificial Plates. Determination of bending strength of stone panel: Calculate the bending stress of stone panel by formula (1), and obtain the standard value of bending strength by mathematical statistics and other methods.

Characteristics of honeycomb aluminum plate:

Aluminum decorative panel

Honeycomb aluminum decorative panels are usually made of 3003, 5005 and other brands, and 1100 plates with low alloy composition are less accepted. Decorative surface to accept spraying or roller coating situation, the coating is polyester or fluorocarbon paint, exterior wall board is best to choose spraying board,arc honeycomb panelHow about the quality and requirements of more than three coating, paint layer thickness is greater than or equal to 40 m, so long-term gas guarantee coating.

Before painting, the aluminum plate needs to be severely anodized to ensure sufficient coating adhesion and bonding strength with the honeycomb core. The panel coating should meet the requirements of the national model YS/T429.2-2000.

　　Honeycomb aluminum plateIn addition to the quality of the selected material, the quality of the honeycomb aluminum plate mainly depends on the bonding quality, and its key technical index is the peel strength. 1 honeycomb aluminum bonding process honeycomb aluminum plate manufacturing generally has 3 kinds of process:

(1) the use of room temperature curing polyurethane or epoxy glue, the use of hand paste or spray glue composite;

(2) the use of epoxy film, the use of hot-pressing composite;

(3) the use of thermoplastic film, the use of flat continuous thermal composite.
