Product Description
During the production of road marking paint,mix glass bead into paint based on the ratio of 18-25% (weight percecentage). 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 PRC No.JT/T280-2004.Standards will be different in countries and areas.According to the specification of Communication Industry Standard of PRC Number GB/T24722-2009,the granulometry is shown as table below:
Ratio:2.4-2.6g/cm;
Reflectivity:≥1.5;
Roundness:>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,KS L2521 ETC.
