How to improve the anti-corrosion performance of aluminum die castings

anti-corrosion
has excellent anti-corrosion properties, maintenance-free, self-cleaning,
good
durability, weather resistance.
anti-corrosion
need
proper coating
the correct coating process during the
of
.
construction should be in accordance with the anti-corrosionstructure of the preparation of coating
craft procedures
and measures to ensure the quality of anti-corrosion layer
China
.surface pre-treatment
after passing the first
primer
interval between the appearance of rust phenomenon, before coating should be re-surface pre-treatment of the rust site. For large
containers that cannot be blasted in a day
it is necessary to seal them to prevent reflow with external gas and extend the rusting time.
conditions at the time of coating should meet the requirements of the product.
in the
, snow, fog, wind and sand and other climatic conditions should stop the anti-corrosion layer of
open
construction. Construction should
when the
temperature is less than -5 degrees C or above 40 degrees C, or the relative humidity is higher than 80%.
construction process should be in different parts of the
coating

wet film thickness
, and timely
coating viscosity
and coating
process parameters
and other adjustments to ensure that the final
thickness
of the anti-corrosion layer to meet the design requirements.
spray is used, the
gun
should move evenly and keep the
nozzle
perpendicular to the spray surface. When
roll coating
method construction,
roller
material should be uniform, should not be too much, rolling when the force should be uniform, and should not be too large, and should maintain a constant speed.
brushing
construction, the application force is uniform, brushing in the same direction, to avoid the surface
the
.weld
,
corners
and uneven surface areas should be more paint or increase the number of times the coating.
