Production process and application of aluminum honeycomb panel？
Aluminum honeycomb panel is a material with excellent impact resistance and strength, which can be considered the fighter jet of aluminum composite panel. It consists of two layers of aluminum plates sandwiching an aluminum honeycomb core arranged perpendicularly to each other. In addition to being able to withstand impacts, it also has good applications such as sound absorption, fire resistance, moisture resistance, insulation, and heat insulation. It is a very good building decoration material and is widely used in places such as subways, airports, stations, malls, and industrial plants. This article will provide detailed information on the application and features of aluminum honeycomb panels.
Structure of Aluminum Honeycomb Panel
The aluminum honeycomb panel is composed of upper and lower layers of aluminum plates and a middle aluminum honeycomb core. They are the outer and core layers, respectively, made of different aluminum materials. Next, we will detail the aluminum plate and aluminum honeycomb core.
The aluminum plate is the outer layer of the aluminum honeycomb panel, consisting of two layers. The thickness of the aluminum plate used is 1.5-1.2mm high-strength aluminum alloy plate. The aluminum alloy plate used for the outer layer serves to prevent deformation and has excellent properties such as corrosion resistance, weather resistance, and dust prevention.
Aluminum Honeycomb Core:
The aluminum honeycomb core is the most important core component of the aluminum honeycomb panel, usually made of 3003 or 5052 aluminum alloy materials. Hexagonal small holes appear in the middle, and these holes are connected to each other to form a strong and hollow structure, thereby improving the rigidity and strength of the aluminum honeycomb panel. At the same time, it also increases sound insulation and thermal insulation functions.
Manufacturing Process of Aluminum Honeycomb Panel
The manufacturing process of aluminum honeycomb sandwich panel is relatively complex. To manufacture a strong and impact-resistant aluminum honeycomb panel, high-grade materials such as advanced coatings are used. Next, we will mainly introduce the production process, which includes four steps: surface treatment of aluminum plate, preparation of aluminum honeycomb core material, coating treatment, and assembly.
1. Surface Treatment of Aluminum Plate:
The surface of the upper and lower layers of the aluminum honeycomb panel needs to be treated first to form properties such as dust prevention, waterproofing, corrosion resistance, and weather resistance. Usually, fluorocarbon coating, polyester coating, etc., are used to achieve these performance requirements.
2. Preparation of Aluminum Honeycomb Core Material:
The aluminum honeycomb core material can be obtained by two different preparation methods: a single-piece method and a continuous method.
(1) Single-piece Method:
The single-piece method is to cut hexagonal small holes on the surface of a large aluminum plate and shape them by folding, pressing, etc. This method can obtain aluminum honeycomb core materials with accurate size and good consistency but has low production efficiency and is suitable for small-batch production.
(2) Continuous Method:
The continuous method is to prepare the aluminum honeycomb core material by stretching, cutting, and pressing the aluminum plate through special equipment. This method has the advantages of high efficiency and high degree of automation, which is suitable for mass production.
3. Coating Treatment:
The upper and lower layers of the aluminum honeycomb panel need to undergo coating treatment to have better properties such as water resistance, dust resistance, corrosion resistance, and weather resistance. Usually, fluorocarbon coating, polyester coating, PVDF coating, etc., are used for treatment.
Assembly is the last step in the manufacturing process of aluminum honeycomb panels, which means gluing the upper and lower aluminum plates and the aluminum honeycomb core together to form a complete structure. Special glue is usually used for bonding, and it is fixed together by hot pressing, vacuum adsorption, etc.
Main Application Fields of Aluminum Honeycomb Panel
The aluminum honeycomb panel has many functions, but mainly it can resist external interference and impact, so it can be used in a wide range of fields and is known as the best building decoration material. It not only plays a decorative role but also provides protection. It is mainly used in building decoration, clean rooms, car, and ship manufacturing.
1. Building Decoration:
As an excellent building decoration material, aluminum honeycomb panels are widely used in various public places and industrial plants. For example, walls, ceilings, partitions, doors, and windows of buildings such as subways, airports, stations, malls, hotels, office buildings, etc., can have multiple effects such as beauty, practicality, fire resistance, moisture resistance, etc.
2. Clean Rooms:
Clean rooms are places with extremely high air cleanliness requirements, which are widely used in industries such as electronics and precision instrument manufacturing. The aluminum honeycomb panel has characteristics such as lightweight, high strength, flatness, not easy to deform, corrosion resistance, and easy to clean,making it an ideal material for clean room walls, ceilings, and floors.
3. Car and Ship Manufacturing:
Due to its excellent impact resistance and strength, aluminum honeycomb panels are also widely used in the manufacturing of cars and ships. It is applied to car roofs, doors, floors, and walls, as well as ship cabins, bulkheads, and decks, providing strong protection and improving safety.
Aluminum honeycomb panels have excellent characteristics such as high strength, impact resistance, sound absorption, fire resistance, thermal insulation, moisture resistance, and flatness. They can be widely used in building decoration, clean rooms, car, and ship manufacturing, providing superior performance and protection.
