Common process
Common anodizing processes include brushed matte natural color, brushed bright surface natural color, brushed bright surface dyeing, and matte brushed dyeing (can be dyed into any color series). Polished shiny natural color, polished matte natural color
, Polished bright surface dyeing, polished matte dyed. Noisy and bright surface color, noisy and misty surface color, sandblasting dyeing. The above plating species can be used on lighting equipment.
Aluminum profile processing flow
1. Aluminum ingots: Before production, according to the production of aluminum ingots of different alloys and different yields, sufficient aluminum ingots, magnesium ingots, silicon ingots, copper ingots and auxiliary materials are equipped.
2. Furnace loading: use a forklift to load the aluminum ingots, compound ingots, and rod ends into the melting furnace.
3. Melting: After adding enough material in the furnace, use natural gas to heat up to 700-730℃, and then the aluminum ingot will melt into a liquid state.
4. Refining: adding various paving assistants to remove impurities in the aluminum water.
5. Put the molten aluminum: Remove the plug of the drain port at the bottom of the furnace, and release the molten aluminum.
6. Casting: The cooling water is turned on after 25~35 seconds after the molten aluminum is filled with the shunt plate. The casting speed is 70~80% of the normal speed, and the speed is raised to the normal speed after dropping by 40-50mm.
7. Homogenization: the aluminum rod is subjected to secondary homogenization treatment.
8. Saw bar: Remove the irregular parts at the front and rear ends of the aluminum bar.
9. Into the warehouse: the aluminum rods are bundled into the warehouse and placed.
Sandblasting + oxidation treatment process:
After the industrial aluminum profile is extruded, there will be obvious stretch marks on the surface, and the surface has large micropores and is relatively rough. It must be sandblasted. The use of emery in the sandblasting process
The impact will cause changes in the surface structure of the aluminum profile. Accompanying the plastic deformation process, the crystals will slip, resulting in an increase in the density of dislocations within the subgrain and the profile surface becoming flatter.
slip.
The surface treatment of industrial aluminum profiles goes through the following steps:
①: Surface sandblasting treatment;
②: Surface pretreatment;
③: Degreasing process for industrial aluminum profiles;
④: Acid etching process for industrial aluminum profiles;
⑤: Alkaline etching process for industrial aluminum profiles;
⑥: Neutralization process;
⑦: Industrial aluminum profile oxidation process;
⑧: Sealing process of industrial aluminum profile;
