325mesh 10/50 µm 40/70 µm 70/110 um 90/150 micron glass beads for sandblasting
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.
Glass beads can be divided into below types based on it’s applications
1.Road marking glass beads
2.Sandblasting glass beads
3.Filling/gringding glass beads
4.Precise glass beads
