Internal mixed glass microbeads for roads

During the production of road paint, glass beads are mixed into the paint at a weight ratio of 18-25% (referencing the Chinese traffic industry standard JT/T280-2004, with variations according to different national and regional standards). After the paint is applied for construction, it maintains reflectivity even after multiple abrasions from vehicle wheels. According to the Chinese national standard GB/T24722-2009, the technical parameters of such glass beads are as follows:
Specific gravity of glass beads: 2.4-2.6 g/cm³
Refractive index of glass beads: ≥1.50
Roundness of glass beads: ≥80%
Magnetic particle content: ≤0.1%
The overall appearance of the glass beads should be colorless, loose, spherical particles, clean and free of impurities, and should not contain agglomerates that do not disintegrate upon light impact.
