Properties of hollow glass microspheres:



1. Good economy


Compared with fillers of other shapes, hollow glass beads have a small surface area to volume ratio and low oil absorption, which can reduce the amount of matrix resin and increase the amount of fillers. At the same time, glass beads with a smaller volume can be filled into larger gaps of glass beads, increasing the total filling amount, further reducing the amount of resin, and reducing the cost. Lightweight glass hollow microspheres can occupy more volume than ordinary fillers of the same weight. This means that hollow glass microspheres have more cost advantages when considering unit volume cost rather than unit weight cost.


2. Reduce viscosity and increase fluidity


The appearance of hollow glass microspheres is spherical. Compared with other irregular-shaped fillers, it is easier to flow and can roll like steel balls in a bearing. Therefore, adding hollow glass microspheres to the composite material can reduce the melt viscosity and The internal stress makes the processing and forming easier, which is conducive to the conventional forming of composite materials.


3. Reduce material density


Generally, fillers have a relatively high density and are added to plastics and rubbers as extenders. Although they can achieve the purpose of reducing costs, they tend to increase the density of the products and affect the performance and use of the products. Because hollow glass beads are hollow products, especially floating beads, the density is very small, about 0.40 ~ 0.75 g/cm3. Now some products, such as some hollow glass beads of 3M company, have a lower density, which can reach 0.125~0.16. g/cm3 level. Adding such low-density fillers to plastics can not only reduce costs, but also make products lighter.

The high-performance hollow glass microspheres have a small particle diameter and are less likely to float up under the same slurry viscosity and shear force. Therefore, it is more conducive to controlling the suspension stability of the system.
The viscosity and shear force required to maintain the suspension stability of the cement slurry system are smaller. Therefore, the cement slurry can be formulated to be thinner, and the fluidity of the cement slurry becomes better, thereby reducing the annulus flow pressure loss during the cement injection process, which is more conducive to Realize balanced cement injection to ensure the cement back to high.


The density is lower, its ability to reduce the density of cement slurry is stronger and faster, and the density can be reduced to the same level with fewer microspheres. The effective cementing component in the system is more cement, so it is more conducive to improvement. The strength of the system, at the same time, can reduce the density to an ultra-low level that is difficult for conventional floating beads to meet the needs of cementing in ultra-low pressure and easy-to-leak formations.
Strong resistance to pressure.

The high-performance hollow glass microspheres have high pressure-bearing capacity and high airtightness, and the density of the cement slurry will not change much. Therefore, it is easier to control the pressure of the annular slurry column, which is beneficial to achieve balanced cement injection.
The composition and performance of the system are stable, which helps prevent cementing accidents and improve cementing quality.
It is more difficult to break when mixing slurry at high speed or mixing slurry with high-power equipment, which is more conducive to preparing cement slurry that meets the design requirements on site.
The particles are fine and can be mixed evenly with cement to produce uniform dry ash.
Reduce damage to the formation.
