Glass beads application (Surface Cleaning of Metal Uses Glass Beads )
1. Road marking glass beads
Can be divided into dropping on type and mixing type;
Using for roading and to raise the safety of night driving by it’s reflective performance.
Dropping on glass beads can be directly dropping on the road marks;
Mixing glass beads need to use together ;
2.Sandblasting glass beads blasting media
Mainly using for the surface sandblasting and shot blasting of metals,glass,rubber and plastics,acrylic,and can avoid the workpieces be damaged.
3. Filling/Grinding glass beads
Mainly using as filling media of weighted-blanket,plush toys,eyeshade,medical package, uniform filled and good textures
Meanwhile can be used as grinding media for paint,oil,coating,pigment,etc.
