Product Features
High-refraction glass beads mainly have retro-reflective characteristics. The so-called retro-reflection is an optical phenomenon. When light hits an object such as a lens, it is gathered after being refracted, and then reflected from the focal point and returned to the direction of the light source by the lens refracting, this is regression reflection. The return fabric has the function of returning most of the incident light irradiated to it according to the original incident rays to improve its own visibility. Therefore, it is made into clothing or other articles, which is very suitable for wearing or carrying by people moving at night or in dark places to improve Own visibility prevents traffic accidents.
Application areas:
Reflective glass beads are the basic material of road marking coatings, mainly used for road markings (heat capacity paint premixed and sprinkled on the construction surface) signs, barrier outline signs, handicraft beads, etc.
Coated glass beads use a high-performance organic silicon material to externally treat the glass beads. After the glass beads are coated, the strong polar groups on the surface become non-polar groups, so that the surface of the glass beads can absorb dust in the air. The phenomenon weakened.
Since the coated beads contain a specific coupling agent, the adhesion between the microbeads and the coating can be improved and some small glass beads can be prevented from being deposited in the coating. The performance of glass beads is even better after coating.
