Hot New Products Microspheres Glass Bubbles - Reflective Glass Beads For Road Markings – Kehui

Glass beads are a new type of material developed in recent years with a wide range of uses and special properties. The product is made of borosilicate raw materials through high-tech processing, with a particle size of 10-250 microns and a wall thickness of 1-2 microns. The product has the advantages of light weight, low thermal conductivity, high strength, good chemical stability, etc. Its surface has been specially treated to have lipophilic and hydrophobic properties, and it is very easy to disperse in organic material systems.
Glass micro-beads are used in the rust removal of aerospace machinery, zebra crossings, no-stop lines, double yellow lines at night reflections on urban traffic roads, and night reflection devices for traffic signs.

Glass beads have a wide range of uses and special properties. They have a very small diameter, light weight and high strength. Adding them to coatings can make them into reflective coatings that people need. Strong retro-reflection performance, to a large extent, the light can be directly reflected back to the light source, so it produces a strong retro-reflection effect. The application of reflective glass beads has greatly improved road safety performance. .

The paint added with road reflective glass beads does not need any power supply, and can also complete the reminder function of night signs. Therefore, road reflective glass beads are used in traffic signal signs, outdoor facilities, road markings and other nighttime warnings. The total number of signs has greatly improved the recognition of these signs at night, played a very good role in guiding and warning, and provided a stronger safety line for drivers who drive at night.

Advantages of road reflective glass beads:

The reflective glass microbead material is directly added to the water-based capsule, and then adjusted evenly. If appropriate, a certain amount of additives can be added to enhance its firmness, and then it can be used directly. Add it directly into the transparent slurry, stir evenly, and add a certain amount of adjuvants according to actual needs to make it get better application effect.

The road reflective glass microbeads can be directly added to the ink to make reflective ink, which can be screen printed or painted on textiles or other items. It is very simple and convenient to use and easy to master. It should be noted that the reflective glass microspheres The amount of beads added can be appropriately added according to the desired degree of reflection.

Spray the reflective base first, and then wait until the reflective base is dry before spraying the reflective topcoat. If the cement surface is constructed, it will be better to spray two layers repeatedly. When spraying, it is recommended to use professional At the same time, when spraying, try a small area in advance, pay attention to the weather conditions of construction, try not to construct in rainy weather, so as not to make the reflective glass microbeads unable to get full play.
