Supersonic Spraying Method For Surface Treatment

       

Supersonic spray surfaces must be sprayed
on the same day to avoid rust and contamination escape. After sandblasting, if
there is rust or contamination, the surface shall be sandblasted first and then
sprayed at supersonic speed.

As the product has a special primer on the
metal surface, it is recommended to use flexible polyurethane one component
moisture curing agent or two-component primer.

For smooth concrete surfaces, supersonic
spraying shall be carried out to ensure that the supersonic spraying surface is
125 microns. Sandblasting or shot peening is an appropriate method to obtain
roughness.

Before supersonic spraying, the surface of
concrete is polluted by oil, grease and dust. It must be cleaned with
detergent. High pressure cleaning of supersonic spraying equipment requires
high adhesion to remove contaminants.

All HVOF sprayed surfaces shall be clean
and dry, free from moisture, dust, oil, grease, surface chemicals and other
contaminants.

Steel or stainless steel surface: the
specific structure of the steel surface must be treated with supersonic spray
tungsten carbide with a roughness of 75 microns. Cleanliness and sandblasting
cleanliness should be close to or close to the requirements of metal white.

Before injecting tungsten carbide by
supersonic spraying, excessive rust must be removed mechanically“ The
"solvent cleaning" method enables you to remove all oil, grease,
welds and other surface contaminants.
