Overview
Shanghai PUSHEN GJ-2 (1.5-2 mm) grinding Glass Bead is a colorless transparent sphere made of Sodium Calcium Glass. Appearance is smooth and round, without obvious bubbles or impurities. It has the characteristics of smooth surface, uniform size, high Hardness, wear resistance and good chemical Stability, and is widely used as a dispersant, grinding medium and filling material in dyestuff, paints, inks, chemical industry and other industries. This model is borosilicate Glass Bead, good toughness and wear resistance, PH value is 7.2, suitable for grinding of medium and low viscosity materials, and can also be used as shot peening beads.
Features
1. Appearance: Colorless transparent sphere, smooth and round, no obvious bubbles or impurities.
2. Stable performance: High Hardness (Mohs Hardness 6-7), Wear resistance, Good Chemical Stability.
3. Excellent physical properties: roundness ≥ 80%, density 2.4-2 g/cm ³, compressire strength > 1200N.
4. Reliable chemical composition: The main component is silica (SiO 2 content > 68%), which is sodium calcium/borosilicate Glass.
5. Wide applicability: PH value neutral (7.2), suitable for grinding and shot peening applications of medium and low viscosity materials.
Principle
Grinding Glass beads are used as a grinding medium to mix with the material to be ground in grinding equipment (such as sand mills). Under high-speed stirring or movement, intense collision and shear force are generated between the Glass beads and between the Glass beads and the inner wall of the equipment, so that the particles in the material are crushed and dispersed to achieve the purpose of refining the particles and uniformly mixing. Its high Hardness and Abrasion Resistance ensure grinding efficiency and service life.
Applications
Dyestuffs, paints, inks, chemicals
