China hollow glass bubble can guarantee the quality of cementing slurry, so as to make it have lower weight and better mobility, and to reduce friction between drilling rods and drilling bits, thus prolonging the service life of the equipment. Third, the drilling fluid configured with hollow glass beads can be recycled twice to prevent pollution.

hollow glass beads can ensure the quality of cementing slurry, so as to make it have a lower weight and a better mobility, and to reduce friction between drilling rods and drilling bits, thus prolonging the service life of the equipment;
In the field of 5G communication and aerospace, hollow glass beads can be used to fill 5G base stations, radomes, cell phone frames and backplanes and IoT devices. First of all, hollow glass beads have low dielectric constant, usually between 1.2-1.8, and the dielectric loss is also controlled between 0.003-0.006, which makes hollow glass beads can play the role of insulation to meet the needs of 5G communication and aerospace applications.
In addition, hollow glass beads can also be used as raw materials for the preparation of ablative materials, which play a role in thermal insulation. Materials made with hollow glass beads tend to be lower in density, dimensionally stable and less prone to deformation.
