AMIGLASS
Glass bead is a new generation of abrasives.
It is also the solution for surface finish not realisable till now.
It
is a micro metric glass shot of high quality, manufactured under the most
modern methods.
It does not make the surface rough and it does not cause edges, but leaves some caps on the treated surface.
It does not create abrasive action on the materialto treat, it gives opaque clearness to the surface and therefore a perfect finishing.
It
leaves no coats and it does not oil.
It presents the highest elasticity and a long life, for this reason sandblasting operations result cheaper.
It is suitable for pressure and aspiration blasting plants by humid and dry processes.
On the contrary to the quartz sand it does not cause silisosis because the SiO2 is chemically binded in the glass.
Sandblasting techniques with glass shot AMIGLASS:
Basis:
Sandblasting is made to modify, improve and increase lightness of surfaces. Abrasives are the tools employed for these techniques. The most updated among these abrasives is the glass shot. The process depends on the mass and the kinetic energy of each grain:
E = (m · vČ) / 2
The smallest grain, which is able to obtain the requested surface treatment will be the best one under an economic and technical point of view.
Sandblasting machines:
Glass shot AMIGLASS can be projected by air and/or liquids on the surface of the piece to be treated:
 |
humid projection makes more soft the abrasive rebound, obtaining finer surfaces (micrometric finishing) |
| |
dry projection (suction or compressed air process) reduces the working times and gives higher performances. |
Sandblasting machine must be provided with cleaning, suction and recovery systems.
In both case sandblasting machines must work in close cycle.
Consumption:
Glass beads consumption depends on different factors:
-
Type of sandblasting machine.
-
Size of grit.
-
Sandblasting pressure.
-
Casting distance.
-
Angle of throwing line.
-
Surface conditions.
Advantages of Glass Beads versus:
Manual cleaning: lower labour costs, higher productivity ratio
Chemical descaling: lower investment and maintenance cost, ecological respect.
Traditional sandblasting: lower grit consumption, wider possibilities of applications
