Aluminum honeycomb panel in ship
1、 Introduction of aluminum honeycomb plate in ship
Aluminum honeycomb composite board is a new kind of marine interior partition material developed by our country and made by domestic green materials on the basis of introducing foreign advanced technology.
The aluminum honeycomb sandwich composite plate is composed of ﹣ fireproof panel + aluminum panel + aluminum honeycomb + aluminum bottom plate. The aluminum panel contains 98% aluminum, 1% magnesium, a small amount of iron and silicon. After H19 ultra cold hardening treatment, its yield strength is 175Mpa, which conforms to American Standard QQ ‐ a ‐ 25026 and British Standard BS 1470. The 3003 aluminum honeycomb core material has a variety of size combinations to achieve the minimum weight and maximum stiffness and strength of the sandwich structure. The main structure of the aluminum panel, aluminum honeycomb core material and fire-proof panel are bonded with Shanghai traveling shark sy8412 adhesive, which ensures the structural integrity of the composite plate and the full play of its various properties It is a kind of solvent-free two-component catalyst free polyurethane adhesive. It is formed by the chemical reaction of hydroxyl compounds and isocyanate to form a hard elastic material. The volume does not change before and after curing. It has good adhesion to the surface of aluminum metal. In the bonding process of the composite plate, a certain pressure is applied to the contact surface, so as to ensure the good contact between the glue and the two layers. After complete curing, the exergy peel strength reaches 30-40n / era, and the exergy shear strength reaches 7.5Mpa (based on German din53282 standard). Aluminum honeycomb sandwich panel has many advantages, such as fire prevention, sound insulation, heat insulation, light weight, high strength, easy to form and strong weather resistance. This product has been widely used in the train and shipbuilding industry, especially suitable for the enclosure separation and decoration materials of modern high-speed trains, high-speed yachts and luxury passenger ships. This material can reduce the dead weight of the train and hull, greatly improve the speed and load capacity of the vehicle and ship, save energy and reduce pollution.
