1. Reflective materials: Glass beads are usually used to make reflective materials, such as reflective road signs, reflective clothing, reflective vests, etc. This is because glass beads have high reflectivity and refraction, which can reflect the incident light back to the original direction and improve visibility and safety.
2. Grinding and polishing: Glass beads can be used as grinding and polishing materials and are widely used for surface treatment of metals, plastics, ceramics and other materials. They can remove dirt, oxides and defects on the surface by friction and friction, making the surface smooth and uniform.
3. Sandblasting and spraying: Glass beads can also be used in sandblasting and spraying processes. In the process of sandblasting, glass beads are sprayed on the surface of the object to remove dirt or increase surface roughness. In the spraying process, glass beads can be mixed with paint to produce special textures and visual effects.
4. Filling materials: Glass beads are widely used as filling materials because of their light weight and insulating properties. For example, in plastic products, glass beads can be used as reinforcing agents to improve the strength and rigidity of materials. In polymer composites, glass beads can be used as fillers to improve the thermal conductivity of materials.
5. Spherical calibration: The size and shape of glass beads are very uniform, so they can be used for spherical calibration, for example, in optical measuring instruments. By placing the glass beads in the calibration position of the instrument, the accuracy and consistency of the measurement results can be guaranteed.
In a word, glass beads are widely used in reflective materials, grinding and polishing, sand blasting, filling materials and spherical surface calibration. Their special properties and shapes make them one of the important materials in many industrial and application fields.
