Introduction:
The glass beads are used for road marking paints and thermoplastic road marking materials to provide excellent night retro-reflectivity .When the headlight shines on the road line ,the light is reflected back ,and then the driver can drive the car safely in night .The rate of glass beads in paint is 15%-25%.The glass beads can be used as intermix and drop-on .we can produce the beads as per the standard of JT/T446-2001 and BS 6088-1981 and other national standard .
Advantages of SICHENG Glass beads:
1. The chemical composition is inert silicon dioxide and there is no worry about the interference of chemical activity;
2, round elastic particles, impact resistance, can be recycled many times, less loss;
3, the spray wear is small, extend the service life of the nozzle;
4, the surface of the ball, will not damage the processing surface and precision size;
5. After treatment, the work-piece surface is smooth, with a special aesthetic feeling, improving the product value;
6. Suitable for dry and wet sand blasting;
7. The fine glass beads used for the metal micro-cracks can be easily displayed after the wet sandblasting;
8, for the processed work-piece with matte effect, highlighting the metal color, not rust and other advantages, no need to carry out pickling derusting treatment.
