Product Description

Reflective glass beads is used to improve the retro-reflection property of the road marking paint. When driving at night, the headlights flash on the marking line with glass beads which makes the headlights reflex back in parallel, so the driver could see the forward way clearly and the driving security is raised at night.

Our main products are reflective glass beads for road marking, Coated Glass Beads, high strength glass beads for sandblasting, grinding. As requested, we can grade our beads in compliance with BS6088,EN1423&EN1424,AASHTO,JIS R3301,AS/NZS 2009:2002,KS, or other detailed standard and specification requirements. The leading products are widely used in a number of major highway sections and sand blasting, shot peening, aerospace electronics applications, and other industries.

The production process of pavement marking glass microshpere is divided into six steps:

  • The production of glass beads should choose raw materials, raw materials determine the quality of the Micro Glass Spheres, raw materials should choose clean glass with good strength and toughness.
  • Then make the glass crush into glass sand, according to the size of the granularity, crushed into a uniform moderate glass sand, in order to save manpower and material resources during burning.
  • The glass sand drying, then use the gas furnace for firing, the natural gas temperature adjusted to 800-1000 degrees, also check the roundness of the glass beads.
  • For glass beads semi-finished products, sieve with the shaker.
  • The screening of qualified glass beads, according to a certain proportion to mix, if you need to coating, need to be completed before stirring.
  • Road Marking Reflective Glass Beads Packing and shipment.
  • reflective glass beads

Product Description

Glass beads are tiny spheres of glass that are used in paint and durable road markings to reflect light back to the driver in dark or poor weather conditions - improving safety and visibility. The glass beads play a very important role in the road safety .During day time the white road marking material gives the sufficient visibility as a contrast to the asphalt. In the night time contrast of the white line is not sufficient and must be improved by adding light reflective glass beads.
