Products Description
Glass beads are an ideal choice for descaling, cleaning, deburring, surface treatment, blasting and precision machining. Glass beads can be effectively used for drying, wetting, pressurizing or sucking.
Cleaning with glass beads can remove the oxide layer and residues on the working material without damaging the surface. Clean the surface before painting or electroplating to ensure better coating performance
Grinding glass beads contain NO FREE SILICA, and are made from superior quality hardened soda lime glass. These glass beads are processed with state-of-the-art rotating oven technology and involves a unique method of rounding, washing, polishing and sieving, and results in a high-quality solid glass sphere.
The glass beads for grinding or dispersing is mainly the cost-effective alternative to the more expensive ceramic beads and used in older, less powerful grinders for performance reasons.
We are experts in the field of wet grinding and our extensive expertise in wet grinding technology allows us to optimize the glass beads used as grinding beads.
High Hardness
The hardness can reach 6-7 Mohs, and have sufficient elasticity, can be used repeatedly several times; not easy to be broken, and have longer service life.
Good Uniformity
Ihe rounding rate is more than 80%, and the particle size is uniform.
Irreplaceable
These beads are not only environmentally friendly, but also chemically stable and will be not react or get reacted with the materials that are ground.
Smooth and No Impurities
The unique process makes the glass beads for grinding free from impurities, clean and have smooth surface. Glass beds have replaced the conventional grinding media like steel balls, pebbles, ceramic balls etc.
