Glass beads are fired through the glass sand. Glass beads can be divided according to the size of the glass bubble (glass bubble is a glass bead, referring to a particle size of 1mm or less solid sphere) and glass beads. By applications can be divided into reflective glass beads, sand blasting with glass beads, glass polishing beads, filled with glass beads. Reflective glass beads which can be divided into safety classes reflective glass beads and silver screen with glass beads; by the refractive index to points, can be divided into ordinary refractive index and high refractive index glass beads. Usually a refractive index of between 1.5-1.64, a high refractive index is generally 1.8-2.2. If, as is most appropriate to use reflective glass beads refractive index of 1.93, the refractive index can be perfectly parallel rays refracted back, so it is not the best reflection refractive index higher. According to the shape of points can be divided into rules and irregular glass beads glass beads. Divided by color can be divided into a colorless, transparent colored glass beads and glass beads.
Endothermic temperature drops, the water acts as a foaming agent to the surface of the glass powder agglomeration, concentrated sodium silicate to the surface, forming shell beads from glass powder and water glass preform formed. Semi-finished beads tower sintering furnace, after melt, foam and annealing process is finished baking beads.
