Microshphere glass for needle grinding

Glass beads blasting media from HAIXU Abrasive was made from glass sand which crushed by glass blocks and plate glass, fused by high temperature in the electric furnace.

Long bead life Glass beads blasting media HAIXU Abrasive can be safe compared to other blast media. In particular, glass bead blast media can be a good alternative to silica sand depending on your application, which while silica sand is still legal it is becoming more regulated and is recognized as a source of a variety of health problems including silicosis.

Related application of Microshphere glass for needle grinding:

Long bead life Glass beads blasting media from HAIXU Abrasive is the common uses for glass bead blasting. Glass bead blasting is well suited for use in sandblasting cabinets where blast media will be recovered. It is effective at cleaning a surface without leaving much of a blast profile. This makes it ideal for cleaning paint or coatings off a part as well as the removal of rust. If a profile is needed though blast media like steel grit or aluminum oxide can be required as glass bead typically doesn’t profile when blasting.
