You don’t know the physical indicators of some glass beads
The physical indicators of common glass beads are as follows: First: The appearance of glass beads: round, transparent, without obvious bubbles and impurities. Second: The main components of glass beads are composed of soda lime glass. Third: The normal softening point temperature of glass beads is: 710-730℃. Fourth: The density of glass beads: 2.4-2.6g/cm3. Fifth: Roundness of appearance: Beads for road reflective lines ≥80%, for industrial shot peening Bead ≥90% Sixth: Refractive index of spherical glass beads: ≥1.5 Seventh: Conventional hardness improvement: Mohs 6-8 This is the performance of conventional glass beads. We understand some characteristics of basic glass beads.
