What is the reflective effect of glass beads? 2019-04-12 The production method of glass beads is to remelt glass powders of a certain particle size through high temperature air, and then use surface tension to form micro beads. High-pressure air or high-temperature gas can also be used to atomize molten glass into microbeads. 1. High refractive index glass beads: mainly used to manufacture engineering-grade reflective film for traffic management signs. It requires glass beads with a particle size range of 37 to 90 m. In addition, since light reciprocates in the glass beads, the glass beads are required to absorb as little light as possible and have high transparency. 2. Quasi-high refractive index glass beads: the refractive index is 1.9 to 2.0. The glass composition and production method are similar to those of high refractive index glass beads, but the content of TIOZ in the glass composition decreases, while the content of BaO and 5102 increases.
