About Glass bead:
Glass beads are made of borosilicate materials by high-tech processing.The particle size of it is 10-250 microns. The product has the advantages of light weight, low thermal conductivity, high strength, good chemical stability and so on. Its surface, after special treatment with oil and hydrophobic properties, is very easy to disperse in the organic material system.
Composition index:
1, Chemical composition: SiO2 >67%,CaO>8.0% MgO>2.5% Na2O<14%, Al2O3 0.5-2.0 Fe2O3 >0.15 other 2.0%;
2, Specific gravity: 2.4-2.6 grams/cubic centimeter;
Appearance: smooth, round, transparent glass without impurities Roundness: ≥85% ;
3. The magnetic particle shall not exceed 0.1% of the product weight;
4. The bubble content of glass beads is less than 10%;
5, Does not contain any silicone components.
Glass bead Usage:
Hollow glass beads have been widely used in artificial agate, marble, glass fiber reinforced plastic bowling materials and high-grade heat insulation coatings.
Hollow glass beads are excellent sensitizers for civil emulsion explosives, which can significantly improve the initiation performance and prolong the storage period of emulsion explosives. In addition, hollow glass beads can also be used to increase the volume in atomic ash, improve grinding performance, improve acid and alkaline resistance.
Considerations
Size and Grade: Glass beads come in various sizes and grades, depending on the application. It’s important to select the appropriate size and grade for specific needs, such as abrasive blasting or reflective road markings.
Safety: While glass beads are generally safe, care should be taken to avoid inhalation of fine particles during use, especially in blasting applications. Proper ventilation and protective equipment should be used.
Cost: The cost of glass beads can vary based on size, grade, and purity. When selecting glass beads, consider both the initial cost and the long-term benefits in terms of performance and durability.
