In the processing of wholesale aluminium composite panels,
spraying is a very important part of the process,
which directly affects the quality of the aluminium composite panel.
Therefore, in the process of processing, attention must be paid to strict control,
after the completion of the entire spraying and baking work and wait for its temperature to reduce,
will be checked for its paint film, the main content includes the uniformity of the paint film, colour, thickness, etc..
One of the paint film off is a very common phenomenon, mainly because in the spraying work,
but also for chroming and other processing, and in these processing, if improper operation,
or processing time does not meet the requirements, it will affect the aluminum veneer adsorption capacity,
adsorption capacity is not strong may cause aluminum veneer paint film off phenomenon.
Then a reason is not to clean directly spraying,
will make the paint film can not be well covered in the aluminum surface,
not only will make the paint film off, the quality of aluminum composite panels will also have an impact.
