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.
