Problems solved by technology

[0003] However, in the general processing and assembly process of the photovoltaic frame, due to the stress problem, the partial anodic oxide film will tear and lose its protection. Although the function of the module will not be lost immediately, the long-term environmental erosion will affect the structure of the frame Stability and strength; and the current frames on the market will have local oxide film bursts in the finishing punching, riveting, etc., and outdoor long-term use will cause oxidation erosion at the bursting film, and change the surface microstructure to make it easier Contaminated with dirt or stained with variegated colors, in harsh environments, vicious corrosion may lead to accelerated disintegration of the load-bearing structure, thereby shortening the actual service life of components and increasing costs
