In the field of chemical raw materials, there is a material that, although not as well-known as plastics or steel. Yet, it plays an irreplaceable role in numerous industries — it is glass powder. This seemingly ordinary powder material actually contains remarkable performance characteristics and wide application value.
What is Glass Powder?
Glass powder is a fine material made from high-quality glass through multiple processes, including cleaning, crushing, grinding, and classification. Depending on the production process and requirements, the fineness of powdered glass can range from dozens of mesh to several thousand mesh.
Performance Characteristics: Small Particles, Big Energy
- Excellent Chemical Stability
Glass powder has outstanding acid and alkali resistance. Glass powder has excellent acid and alkali resistance and is insoluble in acids other than hydrofluoric acid, making it extremely chemically stable. It maintains its performance even in harsh environments. - High Hardness and Abrasive Resistance
It has a Mohs hardness of 6-7. Adding it to materials significantly improves the hardness and wear resistance of the product. This extends the service life of the product. - Excellent Insulating Properties
Glass itself is an excellent insulating material. This property is retained even after being converted into a powder, making it widely used in electronic insulation. - Good Thermal Stability
Excellent high-temperature resistance and low thermal expansion coefficient. Resists deformation or decomposition in high-temperature environments. - Adjustable Transparency and Refractive Index
By adjusting its composition, powdered glass can be made with different refractive indices to meet various optical application needs.
Wide Applications: Indispensable Across Multiple Industries
- Coatings and Inks Industry
Adding glass powder to coatings can enhance the hardness, wear resistance, and scratch resistance of the coating. It also improves the leveling properties of the paint, prevents settling, and boosts UV resistance. Particularly in industrial coatings like floor paints, marine paints, and anti-corrosion coatings, powdered glass has become an essential functional filler. - Plastics and Rubber Industry
When added to plastics, glass powder improves the rigidity, heat resistance, and dimensional stability of the products. In rubber products, it enhances the wear resistance and tear strength of the material. - Electronic Packaging Materials
Due to its excellent insulation properties and thermal stability, glass powder is widely used in electronic component packaging materials. It protects precision electronic components from environmental influences. - Precision Casting
In investment casting, powdered glass, as an important component of the surface layer, improves the surface finish and dimensional accuracy of castings. - Ceramics and Refractory Materials
As a fluxing agent and filler, glass powder lowers the sintering temperature of ceramics. It also can improve product performance, and enhance product quality. - Cosmetics Industry
Ultra-fine spherical glass powder, with its smooth texture and light scattering properties, is used in high-end cosmetics. It provides a silky touch and soft sheen.
