Advantages of Hollow Glass Beads
Weight reduction
It reduces the density of composite materials and achieves weight reduction. Secondly, due to the characteristic of hollow, the use of resin is reduced while satisfying the performance; the development of aviation light weight.
Improving dielectric properties
Since the inside of glass beads is air, which makes the overall dielectric constant of hollow glass beads very low, reducing the loss of high frequency signals.
Improved flow properties
Hollow glass beads are tiny spheres that act as miniature ball bearings in the resin, providing better flowability than flake, needle or irregularly shaped filler particles. The resulting microsphere effect reduces the viscosity of the mix.
Reduced warpage
Since spherical objects are isotropic, filling microbeads can overcome the disadvantage of inconsistent shrinkage rate in different parts caused by orientation, ensure the dimensional stability of products, reduce warpage, and solve the problem that has always existed. Molding of shaped materials and large injection products. Deformation problem.
More economical
The density of high performance hollow glass beads is only 1/5~1/2 of the density of resin, and only a small amount of hollow glass beads is needed to replace other heavier powder materials in the same volume.
Sound insulation
The inside of glass beads is air, air has low thermal conductivity, and the porous material will absorb the vibration of sound waves, thus reducing the heat and hindering the propagation of sound waves.
Application of Hollow Glass Beads
Hollow glass beads as a new type of lightweight material developed rapidly in recent years, have excellent performance and wide application areas. With good product performance and relatively low market price, they are used in aerospace, deep sea buoyancy materials, shipbuilding, oil, natural gas and other military fields, and also have a large proportion of applications in plastics, rubber, paints, coatings, building materials and other civil fields.
In the field of wave-absorbing materials, lightweight, high-absorption, the wide wave-absorbing frequency band is the main direction of future research in aerospace, electronics and many other fields. Hollow glass beads have the advantage of relatively small density due to the unique hollow thin-walled structure, in addition to the metal coating on the surface of the beads, the use of off-shell metal wave-absorbing ability, thereby replacing the density of the metal powder to prepare wave-absorbing materials, so hollow glass beads have a wide range of prospects for wave-absorbing material applications.
Plastic Varieties Suitable for Hollow Glass Beads
Hollow glass beads are used for modification of engineering plastics such as nylon, PP, PBT, PC, POM, etc., which can improve fluidity, eliminate glass fiber exposure, overcome warpage, improve flame retardancy, reduce glass fiber consumption, and reduce cost of production.
Hollow glass beads filled with rigid PVC, PP, PE, production of profiled materials, pipes and plates, can make products have good dimensional stability, increase rigidity and heat resistance temperature, improve product cost performance, increase production efficiency, and reduce costs .
Filling in PVC, PE and other cables and insulating sheath materials can improve the high temperature resistance, insulation, acid and alkali resistance of the product and the processing performance of the product, increase the output and reduce the cost.
Rubber products processing equipment is generally dense refiner, opener, single-screw extruder, etc., because the beads are glass material wall belongs to the rigid particles, in the role of mechanical shear force will be partially broken, the beads will lose its unique functionality after broken.
Hollow glass beads have different models and corresponding parameters, according to different equipment and product requirements to choose the right beads products is extremely important.
When used in the refining machine, there is a rotor on the rubber material shear, beads can not be avoided by the shear force, so as far as possible to reduce the time of beads in the refining, it is recommended to add in the late refining to ensure that the beads added to the refining 3-5min can be dispersed uniformly; in the refining machine, the roller spacing and the refining time of the crushing of the beads have a greater impact, it is recommended that the roller spacing > 2mm, refining time should not be too long; the overall shear force of single screw extruder is small, relatively speaking, the impact on the microbeads is small, it is recommended to increase the extrusion temperature by 5 ℃, reduce the viscosity of the material is more conducive to extrusion molding, reduce the microbeads broken.
