Tips
Causes of Wave Patterns After Floor Grinding
After some floors are ground, sometimes they will have obvious wave
patterns when viewed from the side light. These wave patterns are
like ripple marks after the wind blows over the water surface,
forming some height differences. It not only means that there is a
problem with the flatness of the floor, but also has a great
influence on the decorative effect of the floor.
The height difference of the seams
The difference in height of the seam is the cause of wave pattern
after the partial floor grinding. When paving, the joints of the
two plates are not aligned, and there is a difference in height.
For the alignment of the other joints, the entire plate will be in
a warped state, with one side high and the other low. After
grinding in this way, local wave patterns will be formed.
The paving process is unreasonable
When a large area, obvious wave pattern appears in an area, it is
generally caused by the overall paving process. When paving a large
area, workers sometimes use the drawing method to pave. That is,
nylon thread is used to draw the line in the construction area, and
then along the line to determine the horizontal position and high
and low position of the paving. But this lack of precision method
has some problems.
The selection of grinding discs
Grinding disc is also the cause of the wave pattern on the floor,
which is easy to be overlooked by many people. For the overall
grinding of the floor, generally using the number segment
"50→100→200→400→800→1500→3000". Among them, the first four number
segments have a grinding force, which plays a decisive role in the
overall flatness. The reason is that floor is an inhomogeneous
material, and the hardness of each part of its surface is
different, and the degree of wear resistance is also different.
When grinding, small abrasives will quickly slide from the hard
part to the soft part of the floor under the pressure and speed of
the grinder, causing the soft part to grind deeply, but at the same
time the hard part is scratched and under-grinding, which caused
local wave patterns.
The selection of grinder
In the choice of grinder, the larger the width, the better the
leveling effect. And the larger the coverage area, the larger the
polishing area, so that it is less prone to wave patterns.
