After 315, the quality management of road surface reflective marking has been strengthened in all parts of the country. The standard height of the road traffic marking continuous reflective light is mentioned, and the amount of the pavement marking paint and the surface of the surface of the glass beads are increasing.

According to the incomplete statistics of the marking coating network, the amount of glass beads is estimated to be about 300 thousand tons this year. At present, most of the domestic marking paint manufacturers have no glass beads. The current output ratio accounting, glass bead tension will be greatly intensified, the price will rise in a straight line.

At present, the daily production of glass beads is hovering between 300~400 tons, far from the state of market saturation, and the price of glass beads will continue to rise if the output is not up to the later market (environmental release and new large glass pearl plant production).

Glass bead raw material - glass sand, plate glass sand is the best choice for producing high quality glass beads. At present, it is affected by environmental protection. Flat glass sand plants have been shut down one after another, causing tight supply of glass sand, which directly causes the price of glass bead to rise.
