Selecting the correct glass beads is paramount for achieving desired outcomes in sandblasting operations. As a premier manufacturer and supplier of industrial abrasives, NINGBO INNO PHARMCHEM CO.,LTD. understands the critical role these media play in surface preparation, cleaning, and finishing. This guide aims to assist procurement managers and R&D scientists in making informed decisions when they look to buy glass beads for sandblasting.

The primary function of glass beads in sandblasting lies in their ability to provide a gentle yet effective abrasive action. Unlike coarser abrasives, glass beads are known for their low surface damage and minimal dust generation, making them ideal for delicate surfaces or when a specific cosmetic finish is required. Key properties to consider when evaluating glass beads for purchase include their chemical stability, mechanical intensity, hardness, and roundness. High purity glass beads, specifically those with high SiO2 content, contribute to cleaner blasting environments and less residue on the workpiece.

Size selection is perhaps the most critical factor. Glass beads are available in a wide spectrum of micron sizes, each suited for different applications. For instance, finer grit sizes (e.g., 45-105 μm) are typically used for light cleaning, deburring, and achieving a satin-smooth finish on sensitive materials. Larger sizes (e.g., 425-850 μm) are more aggressive and can be employed for heavier cleaning or peening applications where increased surface roughness is beneficial. When sourcing, always consult with your glass bead blasting supplier to ensure the chosen size aligns with your specific machinery and substrate material.

Hardness, measured on the Moh's scale, indicates the bead's resistance to deformation and wear. Our high hardness glass beads (6-7 Moh's) ensure longevity and consistent performance throughout the blasting process, reducing the consumption rate and cost over time. Similarly, roundness is crucial; a high degree of sphericity (>80%) ensures that the impact is distributed evenly, preventing surface irregularities and optimizing the peening effect. This is why many R&D scientists prefer our glass beads for critical peening applications.
