The application range of stretched aluminum veneer The stretched aluminum veneer is used for the internal and external walls of various buildings, the external facade of the hall, the column decoration, the elevated corridor, the pedestrian bridge, the edge of the elevator, the balcony packaging, the advertising sign, and the surface of the aluminum veneer. The surface of the aluminum veneer is usually treated. Carry out pretreatment such as chromization, and then use fluorocarbon spray treatment. Generally divided into two jackets ? three jackets or four jackets. Fluorocarbon coatings have excellent corrosion resistance and weather resistance, can resist acid rain, salt spray and various air pollutants, have excellent cold resistance and heat resistance, can resist strong ultraviolet radiation, and can maintain color for a long time.?Lasting.
Melting and casting are the first processes in aluminum production. The main processes are as follows:
(1) Composition: According to the specific combination of production, calculate the addition amount of various alloy components, and reasonably match various raw materials.
(2) Smelting: According to the process requirements, the prepared raw materials are added to the melting furnace to melt, and the slag ? gas is effectively removed through degassing ? slag refining.
(3) Casting: Under certain casting process conditions, the molten aluminum is cooled by a deep well casting system and cast into various round casting rods. It is from a contour shape. First of all, according to the design of the profile product part, the mold is manufactured, and the heated round casting rod is extruded from the mold by the machine. Commonly used 6063 brand alloy also undergoes air-cooling quenching process and artificial aging process to complete heat treatment strengthening. Different types of heat treatable reinforced alloys have different heat treatment systems. Coloring (here, mainly, the oxidation process) oxidation: good aluminum alloy profiles have low surface corrosion resistance.
The above is the relevant introduction about the application range of the stretched aluminum veneer.
