As sandblasting abrasive media, BFA has below features:
1. Less dust
Due to brown aluminum oxide’s relatively high specific gravity, it
produces less dust during the sandblasting process. This ensures
operator health and safety and improves operator visibility.
2. High efficiency
The brown aluminum oxide abrasive grits can quickly hit the surface
of the object with sharp edges and corners, it is regarded as a
very fast way of sandblasting.
3. Low loss
The unique size of brown aluminum oxide ensures that more effective
particles hit the surface of the object (such as 30-60 mesh sand,
which can produce 11 million particles per kilogram to hit the
surface of the object, while conventional slag such as 20 mesh can
only produce 1 million.
4. High surface treatment quality
During the blasting process, brown aluminum oxide can penetrate
deep into the caves and pits of the surface to reach the bare
surface of the metal, so it can completely remove all rust,
water-soluble salts and other pollutants.
Application in shoe molds cleaning
1. Guide column, guide sleeve, corrosion mold, steel blasting and
blasting, and mold blasting to remove burrs.
2. The surface of the metal stamping die removes the rough surface
of the old rubber, mold bolt and template workpiece, derusting,
degreasing, descaling, aging rubber, and can also be used for
spraying and pre-plating treatment to improve the surface of the
coating. Adhesion and all surface treatments.
3. It can be applied to sandblasting of large, and heavy
workpieces: such as various types of medical molds, computer shell
molds, plastic molds, automobile molds, gravity pressure molds,
forging molds, etc..
