Aluminum alloy materials are widely used in transportation, marine, aerospace and other fields, especially in some lightweight key components in the fields of automobiles, aircraft, aerospace, ships, etc. Aluminum alloy materials are irreplaceable, so aluminum product manufacturers come Let's talk about the difference between the categories of aluminum sheets.
The manufacturing process of repeatedly using sandpaper to scrape the aluminum plate out of the line, the main process of the process is divided into three parts: deesterification, sand mill, and water washing. In the aluminum sheet drawing process, the special film technology after anodizing can make a film layer containing the metal component on the surface of the aluminum sheet, and clearly show every fine wire mark, so that the metal matte shines with fine hair.
The aluminum plate is placed in the corresponding electrolyte (such as sulfuric acid, chromic acid, oxalic acid, etc.) as the anode, and the aluminum plate is formed by electrolysis under specific conditions and applied current. The aluminum plate of the anode is oxidized, and a thin layer of aluminum oxide is formed on the surface, the thickness of which is 5 to 20 microns, and the hard anodized film can reach 60 to 200 microns.
That is, there is an aluminum plate with a printed pattern thickness of 025 or 03 material on the back. Mirror aluminum plate: refers to the aluminum plate that is processed by rolling, grinding and other methods to make the surface of the plate show a mirror effect.
It can also be called aluminum embossed plate: double-sided pattern, which belongs to aluminum products with various patterns formed on the surface after calendering on the basis of aluminum plate. It is widely used, mainly used in packaging, construction, curtain wall and so on.
The single-sided pattern is formed by rolling a steel rod with a concave and convex pattern. The most common one on the market is the aluminum plate with five rib patterns, which are arranged in relatively parallel according to the five concave and convex patterns, and the difference between each pattern and other patterns is It presents an included angle of 60-80 degrees or a vertical angle of 90 degrees, so this pattern has excellent anti-skid performance. There are large five, medium five, small five, pointer, lentils and other color-coated aluminum plates
The surface of the aluminum plate is treated and then painted or painted by roller. According to the coating process, it can be divided into: sprayed board products and pre-roll coated boards; according to the type of coating, it can be divided into: polyester and fluorocarbon, etc.
The above is a detailed introduction to the categories of aluminum sheets. The aluminum sheets are made of high-quality aluminum alloy sheets as the base material, and then formed by CNC bending and other technologies. The surface is sprayed with decorative coatings. It is a new type of material with light weight, easy installation, and high safety performance. Durable and other features
