Most solar panels are made of aluminum alloy with an uneven cross area. The form of the solar structure is extruded by the aluminum rod with a die, and the surface area effect is acquired by sandblasting and also anodizing.
The selection of resources is extremely rigorous, the content of each component has to meet the following requirements: Si 0.38-0.42%, Mg 0.53-0.57, Fe< 0.18%, see Chemical Make-up is the Determinant of aluminum profile performances
The extrusion die likewise needs to be brightened thoroughly, particularly on the decorative surface area of the aluminum frame, to prevent black lines as well as welding lines. During the extrusion process, the temperature and extrusion rate ought to be strictly regulated. Specifically, after extrusion and also quenching, the synthetic aging time is regulated well, which greatly establishes whether the solidity of aluminum framework material reaches the requirement. Generally, the firmness of aluminum profiles must be over 8HW, which of the solar structure ought to be 12HW.
The aluminum structure after fabricated aging should be sandblasted, as well as the grit of carborundum ought to be uniform. Abrasions should also be avoided throughout sandblasting.
The surface of the aluminum profile after sandblasting developed a matte result, and also after that transferred to the workshop for surface anodizing treatment, black framework product to add an action tinting treatment. The layer's density of average aluminum profiles is about 10μ, while that of solar framework profile needs to be 15μ or more.
l Select the suitable extrusion criteria
According to the extrusion coefficient, profile section, die, tools, and so on, choose the very best extrusion temperature level, casting rod home heating temperature, pass away temperature as well as extrusion rate, as well as constantly adjust these criteria in the manufacturing procedure.
l Enhance the top quality of cast rod
In the process of casting rod, the technology of grain refinement was taken on and efficient steps were required to minimize the problems such as slag incorporation, porosity, and also rugged grain. On top of that, to strengthen the evaluation of the low-strength microstructure of the cast rod bar, quality assurance, minimize the malfunctioning cast rod put into usage.
If you require this type of product or need to know our existing requirements and designs, please call us straight.
The surface area of the aluminum profile after sandblasting formed a matte result, and also after that moved to the workshop for surface area anodizing treatment, black frame material to include a step tinting treatment. The layer's density of common aluminum profiles is concerning 10μ, while that of solar framework profile must be 15μ or more. Anodized products likewise require to be covered to secure the surface area of the product from abrasion during processing.
Framed photovoltaic panels are certainly much better secured during transport than frame-less photovoltaic panels. Also, the PV framework will provide toughness to the entire module.
