Glass Beads

Glass microspheres are a new type of material that has been developed in recent years with a wide range of uses and special properties. This product is made of borosilicate raw materials through high-tech processing, with a particle size of 10-250 microns and a wall thickness of 1-2 microns. This product has the advantages of light weight, low thermal conductivity, high strength, good chemical stability, etc. Its surface has been specially treated to have lipophilic and hydrophobic properties, and is very easy to disperse in organic material systems. Glass beads are used in the rust removal of aerospace machinery, night-time reflection of zebra crossings, no-stop lines, double yellow lines on urban traffic roads, and night-time reflection devices of traffic signs. Ingredient index 1. Chemical composition: SiO2 >67%, CaO>8.0% MgO>2.5% Na2O<14%, Al2O3 0.5-2.0 Fe2O3 >0.15 Others 2.0% 2. Specific gravity: 2.4-2.6 g/cubic centimeter Appearance: Smooth, round, transparent glass without impurities Roundness rate: ≥85% or more 3. Magnetic particles should not exceed 0.1% of the product weight. 4. The bubble content in the glass beads is less than 10% 5. Does not contain any silicone ingredients feature Hollow glass microspheres are tiny hollow glass spheres that are inorganic non-metallic materials. The typical particle size range is 10-180 microns, and the bulk density is 0.1-0.25 g/cubic centimeter. It has the advantages of light weight, low thermal conductivity, sound insulation, high dispersion, electrical insulation and good thermal stability. It is a type developed in 2008. A new lightweight material with a wide range of uses and excellent performance. · Pure white color. It can be widely used in any products that have requirements on appearance color. Light specific gravity and large volume. The density of hollow glass beads is about one-tenth of the density of traditional filler particles. After filling, it can greatly reduce the basis weight of the product, replace and save more production resin, and reduce product costs. Has an organically modified (lipophilic) surface. Hollow glass beads are easy to wet and disperse, and can be filled in most thermosetting thermoplastic resins, such as polyester, epoxy resin, polyurethane, etc. · High dispersion and good liquidity. Since hollow glass beads are tiny spheres, they have better fluidity in liquid resin than flake, needle-like or irregular-shaped fillers, so they have excellent mold filling performance. What's more important is that this kind of small microbeads are isotropic, so there will be no disadvantages of inconsistent shrinkage rates in different parts due to orientation, ensuring that the product is dimensionally stable and will not warp. · Heat insulation, sound insulation, insulation and low water absorption. The interior of hollow glass microspheres is thin gas, so it has sound insulation and heat insulation properties. It is an excellent filler for various thermal insulation and sound insulation products. The thermal insulation properties of hollow glass beads can also be used to protect products from thermal shock caused by alternating between rapid heating and rapid cooling conditions. The high specific resistance and extremely low water absorption make it widely used in the processing and production of cable insulation materials. · Low oil absorption rate. The particles of the sphere determine its minimum specific surface area and low oil absorption rate. The amount of resin can be greatly reduced during use. Even under the premise of high addition amount, the viscosity will not increase much, which greatly improves the production and operating conditions. Increase production efficiency by 10% to 20%. application Hollow glass microspheres are now widely used in synthetic materials such as artificial agate, marble, fiberglass and fiberglass bowling balls and high-end thermal insulation coatings, which can significantly reduce the weight of the product and provide good thermal insulation effects. Hollow glass microspheres are sensitizers with excellent performance for civilian emulsion explosives. They can significantly improve the detonation performance of emulsion explosives and extend the storage period. In addition, hollow glass beads can also be used in putty to increase volume, improve grinding performance, and improve acid and alkali resistance. Features Ingredients SiO2, Al2O3, etc. Characteristics Gray powder Application features: 1. Low price; 2. Enhance the toughness of plastic without reducing its own stiffness; 3. High melting point, which can improve the flame retardant performance and Vicat softening point of the filled material; 4. Good electrical insulation and can be used for filling of highly insulating polymers; 5. Increase the fluidity of the filled material, increase the processing performance of plastics, improve the surface leveling of engineering plastics, and solve the surface problems of glass fiber reinforcement; 6. Can effectively reduce the shrinkage rate of the filled material; 7. The true density is 1.78g/cm3 (bulk density 1.12g/cm3), which can significantly reduce weight compared to engineering plastics filled with glass fiber, calcium carbonate and talc powder; 8. Corrosion resistance; dosage: Air Micro Company recommends that the general dosage of PP and PA is 30-40%, that of HIPS and PBT is generally 7-15%, and that of ABS is generally 5-7%. Usage: In the use of conventional engineering plastics, after the hollow microspheres are modified with silane coupling agent KH-550 in a high-speed mixer, they can be properly mixed with engineering plastic pellets and then directly extruded and pelletized in a twin-screw machine. . 9. The reflection power is particularly strong. The glass bead screen made of it allows us to show outdoor movies in broad daylight. The main purpose 1. Matt surface treatment of stainless steel products 2. Used for cleaning various molds 3. It can remove the tensile stress of various mechanical parts and increase the fatigue life. 4. Cleaning and removing edge thorns before tinning semiconductor devices and plastic packaging tubes 5.
