The main function of the marking machine glass beads is to improve the anti reflection performance of road marking coatings and enhance the visibility of nighttime driving. When the car lights shine on the road markings with road glass microbeads, the light is reflected back in parallel, allowing the driver to see the direction of travel clearly.
Specifically, glass beads serve as reflective materials in road markings, and their reflection principle is that when the car light shines on the surface of the glass bead, the light enters the interior of the glass bead, reaches the bottom, is reflected by the coating, and finally returns to the driver's eyes, allowing the driver to see the road ahead even at night or in low light conditions. In addition, there are strict requirements for the embedding and spreading amount of glass beads to ensure a strong bond with the coating and maintain long-term reflective performance.
The embedding amount of glass beads in the marking machine should be controlled within 1/2~2/3 of the volume to ensure a firm bond with the coating.
The embedding amount of glass beads is crucial for the reflective performance and service life of markings. The volume ratio of glass beads embedded in the coating film needs to be between 1/2 and 2/3, in order to ensure a firm bond between the glass beads and the coating film, improve the durability and reflective effect of the markings. A reasonable embedding amount can enable glass beads to better reflect light after the paint film dries, improving the visibility and safety of road markings.
The reasonable spreading amount of glass beads is 0.3~0.4 kg/m2. The glass beads used for marking paint are generally mixed together with glass beads of different sizes, because after the paint film dries, the glass beads exposed on the surface of the paint film have a reflective effect. When the paint film of the marking paint is gradually damaged, the large glass beads on the surface fall off, and the small glass beads embedded in the internal structure of the paint film are polished and re reflective, so that the marking paint can always maintain its reflective performance.
