1. Product Description
Ceramic Beads blasting are produced by fusing high quality zirconium sand under over 2000 temperature and then made into different micro beads through special technology. The main chemical composition of Zirconia Beads is 60-66% ZrO2.
Ceramic bead blasting media are designed for use with a wide range of substrates, including hard steel, stainless steel, titanium, magnesium, brass, copper and plastics.it is also well suited to high-performance applications in wheel and dry/wet air blast equipment.

3. Application of Ceramic bead blasting
1)Sand blasting: such as plastic. stainless steel,aluminum alloy, copper and other alloy workpieces；
2)Surface Cleaning and Finishing: such as steel pipe,copper pipe and the internal and external part of other metal materialsl:
3)Shot peening: such ad ship building,automobile,machinery and other metal parts;
4)Grinding dispersion
5. Advantages --compared with glass blasting media
1)Reduced beads consumption (30 - 40 times) against glass blasting media；
2)Lower metal surface roughness；
3)Less operating pressure and reduced abrasive velocity needed than glass blasting media；
4)Milk white color, high sphericity and smooth surface；
5)Strong impact resistance and high toughness, but gentle with equipment and tools preserving work parts；
6)No metallic contamination for treated parts；
7)Lower dust production.
