Product Description
Good Impact Resistance Ceramic Blasting Media Zirconia Bead B20-B205 for Iphone Metal Surface Finish
1. Product Description of Ceramic Blasting Media Zirconia Bead B20-B205
Ceramic bead is made by high quality zirconium sand in one electrical furnace under high temperature
over 2000 degrees through special technology,then made into different micro beads.
Ceramic beads and glass beads are two popular blasting media,both has the round solid shape and no
ferrous containmation to the treated workpieces, while glass beads has high breakdown rate and will generate
high dust, it has the hidden danger of silicisis to the operator, people also have to refuel new galss beads because
galss beads has high consumption rate,then the final blasting effect is not so consistent as the one of ceramic beads.
Therefore ceramic beads can replace the glass beads where one clean and high consistent blasting effect is required.

6. Why choose us
Higher clearliness
Our ceramic bead are screened more than six times and blow-cleaning under high temperature,
which provides higher clearliness and ensures it to be work normally in humid weather;
More concentrated particle size distribution
B170(0.045-0.090μm),B205(0.045-0.063μm) is more concentrated than the other one(0-0.063μm) from
other company,which will achieve better blasting effect.
High price/performance Ratio
Our factory is located in the mountain area,where has the lower production cost and environmental cost,
So price is more competitive.
