Road Marking Reflective Glass Beads Lightweight Hollow Glass Beads Hollow Glass Beads

Product Description

Cleaning and polishing of metal objects:
Glass microspheres made of sodium calcium glass have good chemical stability, certain mechanical strength, and hardness. Therefore, as a grinding material, it has great advantages over other grinding materials.
cleaning sandblasting:
Used for cleaning aircraft engine turbines, blades, shafts, etc.:
Used for luxury candle decoration, fillers, and enhancers:
In the chemical industry, glass microspheres can be used as additives and reinforcing agents in production.
Characteristics of sandblasted (shot) glass microspheres:
1. Sandblasting (shot blasting) glass microspheres have both certain mechanical strength and hardness, as well as sufficient elasticity, and can be repeatedly used multiple times with the same effect, making them less prone to breakage;
2. Sandblasting (shot) glass microspheres have uniform particle size, and after spraying, the brightness coefficient of the sandblasting device is kept uniform throughout, making it less likely to leave watermarks:
3. Sandblasting (shot) glass microspheres are made of non alkaline sodium calcium materials, which have good chemical stability and will not contaminate the processed metal:
4. Sandblasting (shot) glass microspheres have a smooth surface and good smoothness, without damaging the mechanical performance accuracy of the processed parts;
5. Sandblasting (shot) glass microspheres appear as spherical particles with very few impurities. Its testing method is strict, the quality is superior, and it can meet the requirements of international and domestic standards.
6. The hardness of sandblasted (shot) glass microspheres shall not be less than 6 Mohs, and they shall have a certain degree of workability, with a roundness rate of not less than 90%.
