Non-slip 유리 구슬 are a game-changer in the realm of road safety, providing enhanced traction and visibility on various pavement surfaces under different conditions. These tiny, yet significant, beads are embedded in road markings and coatings to improve grip and reduce the risk of accidents, especially in wet or icy conditions. This blog explores the different types of non-slip glass beads used for various pavement surfaces and conditions, highlighting their unique properties and applications.
1. Introduction to Non-Slip Glass Beads
Non-slip glass beads, also known as anti-skid or anti-slip beads, are specialized glass spheres designed to enhance the friction and reflectivity of pavement surfaces. When incorporated into road markings or surface coatings, these beads help prevent skidding and improve visibility, making roads safer for drivers and pedestrians.
2. Importance of Non-Slip Glass Beads in Road Safety
Non-slip glass beads are crucial for road safety as they:
- Enhance Traction: Increase the friction between tires and the road surface, reducing the risk of skidding.
- Improve Visibility: Reflect light from vehicle headlights, enhancing the visibility of road markings.
- Adapt to Conditions: Provide effective performance under various weather conditions, including rain, snow, and ice.

5. Application Methods for Non-Slip Glass Bead
The effectiveness of non-slip glass bead is not solely dependent on the type of bead but also on the method of application. Here are the common application methods:
5.1. Drop-On Method
개요
The drop-on method involves applying the beads onto freshly applied road marking materials or coatings.
Process
- Surface Preparation: Ensure the road surface is clean and dry.
- Marking Application: Apply the road marking paint or thermoplastic material.
- Bead Dispensing: Evenly distribute the non-slip glass bead onto the wet marking material.
- Setting: Allow the marking to cure, embedding the beads into the surface.
5.2. Intermix Method
개요
In the intermix method, non-slip glass bead are mixed directly into the road marking material before application.
Process
- Mixing: Incorporate the beads into the marking material.
- 애플리케이션: Apply the bead-infused marking material to the road surface.
- Curing: Allow the material to set, ensuring beads are uniformly distributed throughout the marking.
5.3. Spray Method
개요
The spray method involves spraying a mixture of road marking material and non-slip glass bead onto the pavement surface.
Process
- Preparation: Mix the beads with the marking material in a spray system.
- 애플리케이션: Use a spray machine to apply the mixture evenly on the pavement surface.
- Curing: Let the material cure, securing the beads in place.
