Ceramic Bead Blasting Zirconium Silicate Beads B20 B40 B60 B120
B170 B205 for Surface Cleaning
1. Product Description of Ceramic Bead Blasting Zirconium Silicate
Beads
Ceramic Bead is one clean and durable blasting media,it has smooth
surface,which will not damage the
original dimension of most treated parts. leaves a fine surface and
will not distort or change dimensions
of most parts.
2. The Simple Comparation between Ceramic Beads & Glass Beads
As we know,ceramic beads and glass beads has the similar solid
round shape,while they are different
two blasting media,hereby we just make a simple comparation as
below:
| Item | Ceramic Blasting Beads | Glass Beads |
| Chemical Index | ZrO2 60-66%
SiO2 25-30%
Al2O3 7-13% | SiO2:>65%,
Na2O<14.0%
CaO>8.0%,MgO>2.5%
Al2O3 0.5-2.0% Fe2O3:0.15

|
| Vickers Hardness | ≥700 HV | ≥560HV |
| True Specific Gravity | ≥3.85 g/cm3 | ≥2.5g/cm3 |
| Bulk Density | ≥2.3g/cm3 | ≥1.5g/cm3 |
| Particle Size | 0.04-0.85mm | 0.045-0.85mm |
| Usage | Blasting Media | Blasting Media |
| Ferrous Contamination | No Ferrous | No Ferrous |
| Dust Pollution | Little | Large |
| Recyclable Times | 70-90 | 9-12 |
| %Breakdown | 1.2% | 10% |
| Equipment Wear Rate | Low | Low |
| Blasting Effect | Stain finish
No discoloration | High finish
White discoloration |
Seen from the above chart, ceramic beads is more durable and could
be recycled for 70-90times,while
glass beads only could be recycled for 9-12 times;Ceramic beads
also has quite low breakdown rate,
dust pollution and will provide no discoloration to the treatment
surface.
Therefore,ceramic beads can replace glass beads where a clean and
good blasting effect requires.
3. The particle size of ceramic bead blasting
Ceramic beads has wide particle size from micro size to the very
fine size,it is able to be matched
with various blasting equipment, detail particle size as below:
| Particle Size |
| B20 | B30 | B40 |
| 600-850μm | 425-600μm | 250-425μm |
| B60 | B80 | B100 |
| 125-250μm | 180-250μm | 125-180μm |
| B120 | B170 | B205 |
| 63-125μm | 45-90μm | 0-63μm |
4. Why Ceramic Beads is widely used as one Blasting Media?
Ceramic beads contains 62-66% ZrO2,its fine microstructure ensures
it has the characteristics of high hardness,
strong mechanical resistance,good elasticity,it is more durable,not
easy to be broken in the blasting process;
Ceramic beads has higher density than the one of glass beads,and
lower density than the one of steel shot,it will
make up the upper and lower limit gap between glass beads and steel
shot,therefore ceramic beads is able to
replace them in many applications;
Ceramic beads has lower breakdown rate,then little dust
generated,it will provide a clean and good blasting sight
for the operator;People do not need to refuel the new beads
frequently,the beads will be kept the same shape and
quality in the blasting machine,then it will achieve one more
consistent blasting effect from the first part to the last;
5. Main Applications of Ceramic Bead Blasting
Surface cleaning to remove the rust,oil stain and impurities of
various molds such as glass bottles,tires and dies,
automotive molds,plastics molds,forged and casted metal etc.
Surface cleaning for the inner and outer walls of various metal
pipes such as copper pipes,steel pipes.
6. Why Choose Zirnano Ceramic Beads?
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
B400(0.030-0.063μm) is more concentrated than the other
one(0-0.063μm) from other company,which will achieve
better blasting effect.
