Product Description

Description:

Glass beads was made from glass sand which crushed by glass blocks and plate glass,fused by high tempreture in the electric furnace.

Glass beads is in low heat conduction,nice strength,good chemical stability.

 

Characteristic:

The chemical composition is inert silicon dioxide without disturbance of chemical activity

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 workpiece surface is smooth, with a special aesthetic feeling, improve the product value

Suitable for dry and wet sand blasting

Fine glass beads are used to show metal microcracks easily after wet sandblasting

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:

• Blasting aviation parts by glass beads will eliminate stress, to increase the fatigue strength and reduce friction and wear
• Weld steel workpiece cleaning and removal of surface scratches and other beauty processing; 
• Line cutting clean rust mold;
• The appearance of decorative art; 
•
