China factory made reflective glass beads for traffic road marking
General introductions of China factory made reflective glass beads for traffic road marking
Glass Beads are tiny spheres of glass that used in road marking paint and durable road markings to reflect light back to the driver in darkness or poor weather conditions – improving safety and visibility. The glass beads play a very important role in the road safety.
1. Light color and Slightly odor
2. Excellent affinity with wide range of fillers
3. Good flowability in RMP
4. Low Molecular weight and Low volatility
5. High transparency and High antifriction
6. Weather resistance and Anti-staining
7. Strong adhesion and Quick dryness
Applications of China factory made reflective glass beads for traffic road marking
A type-Reflective glass beads for traffic road marking
Premix glass beads(18-25 %) with hot-melting paint , and then spray on road surface by road line marker.
B type-Reflective glass beads for traffic road marking
First spray road marking paint, and then drop glass beads on surface while paint is still wet.

Processing metohd of China factory made reflective glass beads for traffic road marking
The firing process is an important step in the production of glass beads.
The sand with irregular shape is fired into fine ball by special firing furnace and coking gas or empty natural gas.
Firstly, the coking gas or natural gas is ignited in the furnace body, and glass sand is put into the furnace when the temperature reaches 800 degrees;Sand heated at the same time with the fire up forming, then into the diffusion chamber cooling finalize the design, after the wringer cooling into the vibrating ATreen ATreening, packaging end.This product is physically deformed.
The glass microbead production line USES the principle of the flame floating method to break the recycled waste glass into particles of certain size and send the glass particles into the flame in a certain way. Under the action of the flame, the glass particles become glass beads by softening, melting, beading, cooling and curing.
