Micro Glass Beads For Roadmarking AS/NZS2009:2002 Standards

Reflective Glass Beads
During production of paints, qualified glass beads will be mixed into them as certain proportion required by standards.Certain proportion glass beads will be dropped on during application of paint on road, which has been mixed with glass beads, before they are dry. Under the effect of gravity of glass beads itself, the glass beads will inlaid into paint by part of their surface. When the car light attaches such kind of road marking lines, the light will be reflected back to the eyes of driver to increase driving safety at night.

The glass bead can be separated as intermix beads and drop on beads according to the usage of them, and also can be devided as moisture-proof beads, adhesive coating beads and dual-coated beads.

Intermix Glass beads & Intermix Glass beads & Premix Glass beads

During the production of road marking paint, mix glass bead into paint based on the ratio of 18-25% (weight percentage). After application of such kind of paint on road work, the paint still can keep reflectivity after wear and friction of car wheels. The ratio is referring to the standard of Communication Industry Standard of People's Republic of China No.JT/T280-2004. Standards will be different in countries and areas. According to the specification of Communication Industry Standard of People's Republic of China NumberGB/T24722-2009, the granulometry is shown as table below:

Ratio:2.4-2.6g/cm

Reflectivity: >=1.50

Round ness:>80%

Contained ratio of magnetic particles:<=0.1%

Glass bead should be colorless, loosen and spherical particle, and should be free of impurity, and free of cluster which can't be loosen by slight impact.

We can produce glass beads based on standards of different countries and areas, such as BS6088, AASHTO M247, EN1423/EN1424-1998, KSL2521 etc.
