Description:
Glass beads was made from soda-lime silica glass sand which crushed by glass blocks and plate glass, fused by high temperature in the electric furnace.
Glass beads is in low heat conduction, nice strength, good chemical stability.
The chemical composition is inert silicon dioxide without disturbance of chemical activity.
Features:
Round elastic particles, impact resistant, can be recycled many times with less loss
Small wear to spray, prolong nozzle service life
Round ball surface, will not damage the processing surface and precision size
With glass beads for blasting，the work piece surface is smooth, with a special aesthetic feeling, improve the product value
Suitable for dry and wet sand blasting

Application:
Mainly using for the surface sandblasting and shot blasting of metals,glass,rubber and plastics,acrylic,and can avoid the workpieces be damaged.
Glass beads are a reusable abrasive and are mainly used in blast rooms and blast cabinets. Glass beads contain no free iron to cause corrosion on non-ferrous surfaces, therefor glass beads are very suitable to use on all types of metals. Since it doesn’t create an anchor profile, it is mainly used to clean a substrate without roughening it or to polish the surface. Glass beads also can blasting with compressed air.
It suitable for blasting work as below:
