2.Sandblasting Ceramic Beads B170 size 0.045-0.090mm for metal
surface treatment
DESCRIPTION OF CERAMIC BEADS
Sandblastinge Ceramic bead is also called zirconia sand. It is
zirconia-based blasting media, obtained in melting method and then
blowing into muciro beads. The sandblasting ceramic beads are no
dust, durable and efficient, offering consistent surface finishing,
are new eco-friendly blasting material, widely used for blast matte
finish, blast surface cleaning and surface preparation before
coating or anodizing.
Mainly used in sandblasting machine, including Manual & Automatic
sandblasting machine, Open type sandblasting machine and
Sandblasting machine room, and shot peening equipment, etc.

COMPARISION OF SANDBLASTING OF CERAMIC BEADS VS GLASS BEADS
We have some study on the comparison on cost of blasting and life
against ceramic beads and glass beads.
Ceramic Beads and Glass Beads dosage and solid waste comparison
| Workpiece | Blasting Media | Consumption Mothly | Dust | Dust disposal cost |
| Aluminium alloy | Glass beads 150# | 6 Tons | Much | High |
| Aluminium alloy | Ceramic beads B170 | 0.2Tons | Very Little | Low |
This customer used glass beads to treat aluminum alloy before, and
the monthly consumption of glass beads was about 6 tons. Because
the glass beads are fragile, a large amount of dust solid waste is
generated after use, and additional costs are required to deal with
the solid waste every month.
After replacing glass beads with ceramic beads, the monthly
consumption of ceramic beads is only 0.2 tons, which not only saves
material costs, but also reduces the cost of solid waste treatment
and improves work efficiency.
Ceramic beads is not easy to be broken during sandblasting, and it
is almost no dust pollution , which also improves the working
environment of workers and keeps them away from silicosis hazards.
Remarks:
Under the conditions of different workpieces, different blasting
pressure conditions and blasting requirements, the reduction in the
amount of ceramic beads after replacing glass beads is different.
The above is for reference only.
APPLICATION OF CERAMIC BEADS
1. SANDBLASTING FOR ALUMINIUM PROFILES
In the sandblasting process using ceramic beads as blasting media,
the surface is formed with uniform pits, which are so small that we
can hardly see them with the naked eye. We can only see that the
originally bright aluminum products have become matte.
Sandblasting and anodizing process application:
Widely used in aviation, electrical, electronic digital industry,
machinery manufacturing, automobile, construction, light industry
and other industries.
Sandblasting process classification:
According to different workpiece materials, anodizing treatment is
divided into ferrous metals (steel) and non-ferrous metals
(aluminum, copper, magnesium and their alloys);
The advantages by ceramic beads sandblasting are:
1. Remove the oxide film on the surface of aluminum profile
products, whether it is a naturally formed oxide film or an
anodized film, it can be completely removed after sandblasting.
This is why the sandblasting process precedes the anodizing
sequence.
2. Prepare for other surface treatment procedures. When the
aluminum profile after sandblasting is electroplated, the bonding
force of the electroplating layer is stronger. The sandblasted
aluminum profile can also be sprayed to enhance the coating
adhesion.
2. OTHER APPLICTIONS
Includes metal surface treatment, metal rust removal, hardware rust
removal, stainless steel material sandblasting, copper material
sandblasting, hardware paint removal, hardware scar removal,
aluminum alloy deburring, Zinc alloy blasting finish. etc.
