Ceramic Beads Blasting Media for metal blast pretreatment before
coating / plating
DESCRIPTION
Ceramic beads also called ceramic media, ceramic bead blasting media, or ceramic blasting beads.
It is of high hardness, good elasticity, high gloss and high impact
strength. Ceramic blasting beads
mainly used for blast cleaning, debluring, removing oxice layers of
castings and forging parts, also
for metal surface finishing, and pretreatment before coating and
plating.

APPLICATION
Ceramic beads can be used for blast pretreatment beforecoating or
plating.
Among all surface cleaning methods, the ceramic beads sandblasting
method is a thorough, universal, and extensive method, because:
1. Sandblasting is more efficient, thorough and cheaper than other
pretreatment processes.
2. The sandblasting process allows you to freely choose the
cleanliness and roughness of your workpiece.
Sandblasting with ceramic beads can produce a uniform and uneven
rough surface on the cleaned surface to facilitate mechanical
bonding of the coating. Using clean compressed air to drive clean
ceramic sand to spray on the surface of the workpiece can generate
compressive stress on the surface of the substrate, remove the
surface oxide film, and cause lattice distortion of part of the
surface metal, which is conducive to the physical bonding of the
coating. The substrate metal can be sandblasted to obtain a clean,
rough and highly reactive surface. This is an important
preprocessing method.
The quality of the pre-treatment of the sandblasting process
affects the adhesion, appearance, moisture resistance and corrosion
resistance of the coating. If the pretreatment work is not done
well, the rust will continue to spread under the coating, causing
the coating to fall off in pieces.
