Construction Requirements of Reflective Glass Beads

The new pearlescent reflective material is a new concept of reflective material, which can overcome the defects of traditional marking and greatly improve the safety level of road marking. No matter in the daytime or in the rainy night, it can still bright reflect light, make vehicles walk all the way and ensure driving safety in rainy night. It is a replacement product of ordinary glass beads. The embedding degree of the bright reflective glass beads for road marking in the reflective material reaches about 60%. The construction amount of the bright reflective glass beads should be 180 ~ 200g /㎡。 After one year's use of the road marking of Penghu Expressway in Jiangxi Province, the dry reflective brightness remains at 200 MCD / Lux / ㎡, the wet reflective brightness is also maintained at 150 MCD / Lux /㎡.At the same time, the highlighted reflective glass beads used in the reflective material have been specially treated against pollution with excellent anti pollution ability and further enhanced durability. While playing the safety role of road marking, it can also greatly reduce the maintenance cost in the later stage of road marking.

Construction requirements of new pearlescent reflective materials

When the new pearlescent reflective material is used for marking construction, the following requirements should be met in the construction process: ensure that the settlement degree of reflective glass beads in the material reaches 50% - 60%, too much settlement will cause the initial reflection coefficient to be small and insufficient settlement will lead to insufficient fastness. At the same time, the construction amount of reflective glass beads should be 180 ~ 200g / ㎡. This reflective material has no special requirements for construction equipment and it is suitable for all known reflective marking construction equipment. In the process of construction, there is no need to make any transformation to the construction equipment, just replace the ordinary glass beads with this material. As the fluidity and particle size of this material are slightly different from that of ordinary glass beads, the parameters in the construction process should be adjusted appropriately. For spray type marking equipment, the spraying pressure of glass beads should be increased appropriately. For hot-melt marking equipment, the spreader and melting temperature should be adjusted properly. During the marking construction, the marking constructors can still operate and construct according to their own construction methods and habits without adding new equipment. During construction, the construction requirements should be followed.

To sum up, road traffic markings play an important role in ensuring road traffic safety, especially in the road traffic at rainy night, good reflective effect can play a good role in guiding vehicle driving, and thus avoid the occurrence of traffic accidents. After the repeated tests and road site verification, the new pearlescent reflective material has significantly improved the reflective effect compared with ordinary hot-melt materials; on the other hand, the outstanding anti pollution ability and durability of the new pearlescent reflective material can reduce the risk of damage to the road marking, extend the maintenance cycle of the road marking, and save a lot of costs for the later operation and maintenance of the road marking Use. Therefore, the new pearlescent reflective material has a good application value in road marking.
