Surface Profile
|
|
The
degree of profile on the surface affects a coating’s overall performance. The
height of the
|
|
profile
(measured from the peaks to the troughs) determines aspects such as adhesion,
coverage
|
|
and overall
volume of coating used. If the profile is too large the amount of coating
required to
|
|
ensure
adequate coverage increases, otherwise there is a danger that the peaks
remain uncoated
|
|
-
allowing rust
spots to occur. If the profile is too small, there may be an insufficient key
to produce
|
|
adequate adhesion,
leading to premature coating failure. Ensuring the correct surface preparation
|
|
optimises the
performance of the coating and material usage.
|
|
|
|
There are four different methods available for testing surface
profile:
|
|
-
Surface Comparators
|
|
-
Replica Tape
|
|
-
Surface Profile Gauges
|
|
-
Surface Roughness Testers
|
|
|
|
This
easy to use gauge measures the peak-to-valley height of a blast cleaned
surface.
|
|
|
|
The
average of a series of measurements provides an indication of the surface
roughness and allows
|
|
the surfaces
to be compared as blasting proceeds.
