Oxide Aluminum Solar Panel Frame Kit AA10 PV Aluminum Profile
Border
The cross-sectional shape of the solar frame is not regular, There
are slots on it to facilitate the installation of the panel. The
surface is silver matte, and some are black. The shape of the solar
frame is extruded by the aluminum rod through the mold, and the
surface effect is obtained by sandblasting + anodizing.
Generally, solar panels will be exposed to the sun and rain
outdoors for many years, and the bad weather such as wind, snow and
hail will also pose a threat to the solar power station. Therefore,
the quality requirement of the aluminum frame of the solar panel is
higher than that of the general industrial aluminum profile.
The selection of raw materials is very strict, and the content of
each element must meet the following standards: si0.38-0.42%,
mg0.53-0.57, Fe < 0.18%, the content of other elements must be
within the range specified by the state, the purity of molten
aluminum should be high, and the recycled materials can’t be used,
that is, the anodized materials can’t be remelted to cast aluminum
rods, so as to avoid small black spots and burrs or ash inclusions
on the surface of profiles during extrusion, which will affect the
surface quality of profiles, The surface of the profile will be
blackened due to the unqualified mixed materials.
The extrusion die also needs to be polished carefully, especially
the decorative surface of the aluminum frame, to avoid black lines
and welding lines. The temperature and extrusion speed should also
be strictly controlled during the extrusion process. Especially
after the extrusion quenching treatment, the artificial aging time
is well controlled, which largely determines whether the hardness
of the aluminum frame material meets the standard. Generally, the
hardness of aluminum profiles should be above 8hw, while the solar
frame aluminum profiles should reach 12HW.
The frame aluminum profile after artificial aging shall be subject
to sandblasting treatment. The sandblasting machine is made of
carborundum, and the sand particles shall be uniform. In the
sandblasting process, it is also necessary to prevent scratches.
The surface of the aluminum profile after sandblasting will form a
matte effect. After that, it will be transferred to the oxidation
workshop for surface anodizing treatment. The black frame material
will be further colored. The oxidation time should also be
specially controlled to increase the thickness of the oxide film.
The oxidation thickness of ordinary aluminum profiles is generally
10μm, And the thickness of the oxide film of the solar frame
profile should reach 15 μm.
The material after anodizing also needs to be coated to protect the
surface of the material from being scratched during processing. The
frame material after the film is applied can be transferred to the
deep processing workshop for sawing, blanking, punching and
riveting.
Each of the above processes shall be subject to strict inspection,
and unqualified products are not allowed to flow into the next
process. It seems that the production of solar photovoltaic modules
is also very complicated and strict. Each set of finished frames
packed by us is strictly inspected through n processes.
