Aluminum sheet. Panzhu has a widest width of 600mm, and there are also more rows). Aluminum rod, diameter: 3-500mm aluminum tube, thickness: 2-500mm: aluminum tube, aluminum plate, aluminum rod Panzhu theoretical calculation formula. (Note: there is an error with the actual weight, the dimension unit is mm) Aluminum plate weight (kg) = 0.0000028 × thickness × width × length Aluminum tube weight (kg) = 0.00879 × wall thickness × (outer diameter - wall thickness) × length aluminum rod Weight calculation formula (kg) = diameter × diameter × length × 0.0000022
Brushed aluminum plate: The manufacturing process of repeatedly scraping the aluminum plate out of the line with sandpaper. 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. Silky sheen.
Alumina plate: The aluminum plate is formed by placing the aluminum plate in the corresponding electrolyte (such as sulfuric acid, chromic acid, oxalic acid, etc.) as the anode, and performing 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.
PS aluminum plate (advertisement aluminum plate, also known as printed zinc plate, newspaper plate): that is, an aluminum plate with a printed pattern on the back and a thickness of 025 or 03.
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.
Embossed aluminum plate can also be called aluminum embossed plate: it is an aluminum product that forms various patterns 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.
Aluminum Al: balance; silicon Si: 0.25; copper Cu: 0.10; magnesium Mg: 2.2-2.8; zinc Zn: 0.10; manganese Mn: 0.10; chromium Cr: 0.15-0.35; iron Fe: 0.40.
Tensile strength (σb ): 170~305MPa
Conditional yield strength σ0.2 (MPa)≥65
Elastic modulus (E): 69.3~70.7Gpa
Annealing temperature: 345°C.
The specific cleaning steps of the aluminum plate are as follows:
1. Rinse the surface of the board with plenty of water;
2. Gently wipe the surface of the test board with a soft cloth soaked in detergent diluted with water;
3. Rinse the board surface with plenty of water to wash away the dirt;
4. Check the board surface, and focus on cleaning with detergent for the places that have not been cleaned;
5. Rinse the board surface with clean water until all the detergent is washed away.
Note: Do not wash the hot board (when the temperature exceeds 40 °C), because the rapid evaporation of moisture is harmful to the board surface paint!
It should be noted that, please choose the appropriate detergent, a basic principle is: be sure to choose a neutral detergent! Please do not use strong alkaline detergents such as potassium hydroxide, sodium hydroxide or sodium carbonate, strong acid detergents, abrasive detergents and paint-dissolving detergents.
