The main reasons for the uneven sand blasting


The main reasons for the uneven sand blasting are as follows: three.
(1) the speed of the spray gun is unstable when the sand blasting equipment.
When the walking speed of the spray gun is slower and the walking speed is faster,
In the unit time, the sand is the same, but the distribution area of sand is smaller and larger,
Due to the same number of sand distribution in different areas of the surface, there will be a dense phenomenon.
(2) the pressure instability of sandblasting machine during operation.
When an air compressor is used for multiple spray guns, the pressure is difficult to stabilize,
When the air pressure is high, the sand will be sucked and ejected. When the air pressure is low,
it will be the opposite.
The amount of sand discharge is more, the sand surface will be dense,
and the sand will be sparse when the amount of sand is small.
(3) the distance between the spray gun and the surface of the workpiece is too large.
Spray gun muzzle near the surface of the product, the scope of spray is small, but relatively concentrated, dense.
Spray gun muzzle away from the surface of the product, although the sand spray is still so much,
but the size of the jet expanded, then it will appear sparse.
