Glass Bead Description
Glass Beads are manufactured using advanced processing techniques, including direct melting of new glass through titration, forming in deionized water, high-temperature hardening, and subsequent polishing. The sphericity is 100%, with no air bubbles inside the beads, providing excellent wear resistance. This product is ideal for economically dispersing and grinding low-viscosity slurries and serves as a cost-effective configuration for traditional sand mills.

FAQs
Q1. What are Glass Beads?
Glass beads are small, spherical particles made from high-quality glass. They are commonly used as grinding media, in blasting, and as reflective materials in various industrial and commercial applications.
Q2. What are the primary uses of Glass Beads?
Abrasive Blasting: Used in sandblasting to clean, polish, or finish surfaces.
Grinding Media: Employed in milling and grinding processes, especially in industries like paint, ink, and cosmetics.
Reflective Material: Applied in road marking paints and signs to enhance visibility at night by reflecting light.
Filtration Media: Used in some filtration processes due to their uniform size and chemical inertness.
Q3. What are the key properties of Glass Beads?
High Sphericity: Provides uniform impact and coverage in blasting and grinding.
Chemical Inertness: Resistant to most chemicals, making them suitable for a wide range of applications.
Non-Porous Surface: Prevents absorption of liquids and contaminants, maintaining purity in grinding processes.
Durability: Glass beads are tough and can withstand multiple uses without significant degradation.
Q4. What sizes are available for Glass Beads?
Glass beads are available in various sizes, typically ranging from a few microns to several millimeters in diameter. The size chosen depends on the specific application, with larger beads often used for blasting and smaller beads for grinding.
