Key Considerations When Selecting Glass Beads

　　Today, glass beads are being used in an ever-wider range of applications. For instance, road markings on highways are painted with glass beads embedded in them, making the markings more visible. Glass beads are also widely used in sandblasting, shot peening, and grinding processes. Moreover, they find application in a variety of precision instruments, such as medical devices and aircraft components. As technology continues to advance, the scope of these applications keeps expanding, which means that the number of customers purchasing glass beads is steadily growing. But when selecting glass beads, what key factors should you pay attention to? Let’s take a moment to summarize them together.

　　When purchasing, there are basically four key factors to consider: transparency, roundness rate, cleanliness, and the material of the glass raw materials. First is transparency—higher transparency in glass microbeads indicates better quality in terms of light reflection. The roundness rate must meet national standards to be considered a qualified product; the national standard requires a roundness rate of at least 70%. Next is the cleanliness of the glass microbeads. Similar to the principle behind transparency, higher cleanliness means higher reflectivity. Microbeads with poor cleanliness likely contain impurities, making them unqualified products. Finally, there’s the raw material—the glass itself. Glass microbeads are primarily made from glass, so the quality of the glass is a crucial factor affecting the quality of the microbeads. Different glass raw materials should be selected based on the specific application. For example, products made from ordinary glass, such as those used for wine bottles, will differ in their applications from those made from tempered glass that has been crushed.
