Glass microspheres have a very important role in production and life. The glass micro -balls are not only light quality, low heat conduction, high strength, and good chemical stability, but also have the performance of hydrocariasis on the surface, which is easy to scattered in the organic material system. So what are the main characteristics of glass microspheres?
Main features of glass microspheres
1. There is a scattering effect on visible spectral range light. The glass material is actually colorless and transparent, but because the glass ball has a scattering effect on the full visible spectral range of the spectral range, it looks white. However, when it is added to the color material, it is also scattered with the light of the material color, so it can be widely used in any material required by the appearance and color without affecting the color of the original material.
2. Lear density. The density of glass microspheres is about one -third of the density of traditional filling particles. After filling, it can greatly reduce the base weight of the product, and the large volume makes it replace a large amount of other raw materials and reduce the cost of the product.
3. It has parental oil. Weting and decentralizing hollow glass microspheres can be filled in most thermal thermoplastic resins, such as polyester, epoxy resin, polyurethane, etc.
4. High decentralization and good liquidity. Because the glass micro -ball is a tiny ball, it is more liquid than the fillers of the liquid resin than the chip, needle, or irregular shape, so the model is excellent. What’s more important is that this small micro -ball is different, so it will not produce disadvantages of inconsistent contraction rates caused by different parts of the orientation, ensuring the size of the product stable and not warpage.
5. Low water absorption. The interior of the glass microsphere is thin gas, so it has the characteristics of sound insulation and heat insulation. It is an excellent fillers for various insulation and sound insulation products. The heat insulation characteristics of glass microspheres can also be used to protect the heat shock caused by alternate changes between the products and the conditions of rapid heat and cold. The high ratio resistance, the extremely low water absorption rate allows it to be widely used in processing and production cable insulation materials.
6. Low oil absorption. The particles of the sphere determine that it has the smallest surface area and low oil absorption rate. During the use process, the amount of resin can be greatly reduced. Even if the amount of high addition is added, the viscosity will not increase much, which greatly improves the production operation conditions. Increase production efficiency by 10%to 20%.
