Glass Bead
Description:
Glass Bead is a unique and popular air-blasting abrasive for cleaning and conditioning surfaces. It is manufactured from high-grade glass, annealed in its spherical shape to equalize internal stresses and resist fracture. In addition, the inherent strength of glass beads is such that they can survive multiple impacts, allowing for economies of continuous recycling.
Application
Its applications include cleaning mould, glass carvings, and decorative works in the glass industry, removing rust and corrosion without disturbing the base material, and blasting for cleaning and conditioning surfaces without changing their dimensional tolerances or contaminating them.
