The surface quality of solar frame aluminum profiles is not good.
The deformation and curvature of the solar frame light fixture is caused by the fact that the surface quality of the solar frame aluminum profile is not good, and defects will appear over time , such as bending, twisting. and deformation. Simply remove the heat collector tube and water bucket, brace them and then reinstall them.
How is the aluminum solar frame made? We currently use a gray frame. After removing the profile, oxidize it and then spray it gray?
The reasons are the formation of an oxide layer, material reasons, manufacturing process and environmental factors.
1. Oxide layer formation: The oxide layer on the surface of the aluminum frame will gradually form over time. The existence of the oxide layer can cause the appearance of liblack genes on the frame surface.
2. Material reasons: The materials of the aluminum frame and welding wire may not match, resulting in corrosion, reaction, etc. during use, thus forming black lines.
3. Manufacturing process: There may be problems with the manufacturing process of the aluminum frame and welding lines, such as insufficient cleaning and surface treatment, resulting in black lines during use.
4. Environmental factors: Factors such as humidity and high temperature in the usage environment may also affect the aluminum frame and welding wires, resulting in black lines appearing.
Yes. Firstly, the extrusion die is opened according to the frame design, and the material is extruded for aging treatment and then surface treatment. You are using a gray frame which needs to be coatedpowder or fluorocarbon. After completing this, we will carry out the finishing treatment on the positioning holes, drainage holes, etc. based on your actual installation needs.
