POWDER COATING ALUMINUM PROFILES
With the continuous
development of powder coating technology, electrostatic powder coating on the
surface of aluminum profiles is widely used by the current powder coating
technology due to its unique advantages. The main features are recycling rate
of more than 95%, no pollution to the environment, powder coating under normal
temperature conditions without pre-heating, thick film layer can be formed at
one time, no hanging phenomenon and so on.
The powder coating
is sprayed on the surface of the aluminium profile with an electrostatic powder
spraying device. Under the action of static electricity, the powder will be
uniformly adsorbed on the surface…
