• Purpose Of The Signage Aluminum Composite Panel

  The Signage Aluminum Composite Panel is a composite plate steel plate composed of a carbon steel base layer and a stainless steel coating. Its main feature is the strong metallurgical combination of carbon steel and stainless steel. It can perform various processes such as hot pressing, cold bending, cutting, welding, etc., and has good process performance. Introduction As the base material of the stainless steel composite plate, various common carbon steels and special steels such as Q235B, Q345R, and 20R can be used. The coating material can be stainless steel of various grades such as 304, 316L, 1Cr13 and duplex stainless steel. The material and thickness can be freely combined to meet the needs of different users. Stainless steel composite plate not only has the corrosion resistance of stainless steel, but also has the good mechanical strength and processing performance of carbon steel. It is a new type of industrial product. Stainless steel composite plates have been widely used in petroleum, chemical, salt industry, water conservancy and electric power, and other industries. As a resource-saving product, stainless steel composite plate can reduce the consumption of precious metals and greatly reduce the construction cost. To achieve the perfect combination of low cost and high performance has good social benefits. Production application production method How is stainless steel composite plate produced? There are two main methods for the industrial production of stainless steel clad plates, explosion lamination and hot rolling lamination. The production process of the explosive composite plate is that the stainless steel plates are superposed on the carbon steel substrate, and a certain distance is separated between the stainless steel plate and the carbon steel substrate with a mat. Explosives are tiled on the stainless steel plate, and the energy of the explosive explosion causes the stainless steel plate to hit the carbon steel substrate at high speed, generating high temperature and high pressure, so that the interface between the two materials is solid-phase welded. Ideally, the shear strength per square millimeter of the interface can reach 400 MPa. The hot-rolled composite plate process is based on the carbon steel substrate and stainless steel plate being physically pure and rolled under high vacuum conditions. The two metals diffuse during the rolling process to achieve a complete metallurgical combination. Of course, in order to improve the wetting effect of the composite interface and increase the bonding strength, a series of technical measures must be taken in the physical and chemical treatment of the interface. The above two composite board manufacturing methods are in accordance with the national standard GB / T8165-2008. This standard is not equivalent to the Japanese JISG3601-1990 standard, the main technical indicators are the same or higher than the Japanese standard.
• Classification Of Galvanized Steel Composite Panels

  classification There are many varieties of Galvanized Steel Composite Panels, and they are a new type of material. Therefore, there is no unified classification method so far, and they are usually classified according to use, product function and surface decoration effect. Classified by purpose a. Aluminum-plastic panel for building curtain wall The minimum thickness of the upper and lower aluminum plates is not less than 0.50mm, and the total thickness should be not less than 4mm. The aluminum material should meet the requirements of GB / T 3880. Generally, aluminum alloy plates of 3000, 5000 and other series should be used. b. Aluminum-plastic panel for exterior wall decoration and advertising The upper and lower aluminum plates use rust-proof aluminum with a thickness of not less than 0.20mm, and the total thickness should not be less than 4mm. The coating is generally fluorocarbon coating or polyester coating. c. Aluminum-plastic panel for indoor use The upper and lower aluminum plates are generally 0.20mm thick and the minimum thickness is not less than 0.10mm. The total thickness is generally 3mm. The coating is polyester or acrylic. Classified by product function a. Fire board The flame retardant core material is selected, and the product's combustion performance reaches flame retardant grade (B1 grade) or noncombustible grade (A grade); at the same time, other performance indicators must also meet the technical specifications of aluminum-plastic panels. b. Antibacterial and mildew resistant aluminum-plastic board The coating with antibacterial and bactericidal effect is coated on the aluminum-plastic plate, so that it has the function of controlling the microbial activity and reproduction and finally killing bacteria. c. Antistatic aluminum-plastic board The antistatic aluminum-plastic board is coated with an antistatic coating on the aluminum-plastic board. The surface resistivity is below 109Ω, which is lower than that of ordinary aluminum-plastic boards. Therefore, it is not easy to generate static electricity, and the dust in the air is not easy to adhere to its surface.
