Hollow glass microsphere is a kind of hollow, thin-walled, high-strength, smooth surface micro sphere, which is a new micro scale lightweight inorganic material developed in the 1950s and 1960s. In addition to the advantages of low density, high strength, low heat conduction, high wave transmission and good stability, it also has excellent properties that other non-metallic mechanical materials do not have, such as insulation, self-lubricating, sound insulation, fire resistance, corrosion resistance and radiation protection. Therefore, it is widely used, even indispensable in some special fields.

In the early years, it was found that some by-products of fly ash were pearl like hollow microspheres with a diameter of 20~200 under the microscope μ The shell thickness varies from 5% to 30% of the diameter, and its main components are SiO2, Al2O3, CaO, MgO, Na2O, K2O, etc. This kind of sphere has small specific gravity, high surface pressure, strong wear resistance, good flame retardancy, good acid resistance and high temperature resistance, so it has been exploited for new functions. At the early stage of the development of artificial hollow glass beads, due to the high cost, they were mainly used in cutting-edge fields such as aerospace and national defense. Later, the United States and Japan took the lead in the research and development and mass production of hollow glass beads, which formed a situation where hollow glass beads were monopolized by foreign countries and became one of the neck materials in China.

With the development of science and technology in China, hollow glass beads can be industrialized in China, and gradually become a new functional material with relatively low price and rich functions, which has been widely used in military and civilian fields such as thermal insulation materials, insulation materials, composite materials, petrochemical, coatings, rubber, etc.

When visiting the application exhibition hall of Shenglaite, the technicians introduced to the small group that Shenglaite’s hollow glass beads have been successfully applied in more than 20 downstream fields, including daily consumer goods, industrial supplies and cutting-edge aerospace fields.

In terms of 5G communication, hollow glass beads can help improve the transmission rate because their hollow glass material has a low dielectric constant of 1.0~2.0. At present, downstream applications involved include 5G base station and radome materials, 5G mobile phone middle frame and backplane, Internet of Things equipment, etc.

In terms of lightweight of rubber, elastomer and vehicles, hollow glass beads have a good role in reducing the specific gravity, which can reduce the weight of rubber and plastic composites by 8%~10%. In addition, hollow glass beads can also effectively improve the processing performance of materials, increase rigidity and resilience, and improve a series of special functions of materials, such as heat insulation, sound insulation and noise reduction, and flame retardancy. They are widely used in shoes, flexible pillows, car shells, special parts and other products.

In the coating industry, the characteristics of hollow glass microspheres, such as micron particle size, microsphere effect and hollowness, endow the coating with better heat insulation and heat preservation effect, and create a new cooling coating integrating reflection, radiation and efficient heat insulation. It is not only used in military and aerospace equipment, but also widely used in oil pipelines, oil storage tanks, communication base stations, large grain storage silos and other industries.

As an anti-corrosion coating, the addition of hollow microspheres makes the product have better antifouling, anti-corrosion, anti ultraviolet, anti yellowing, and scratch resistance effects, which can be widely used in weather resistant sunscreen and thermal insulation outdoor coatings, automotive coatings, ship antifouling coatings, anti-corrosion coatings, etc.

In the adhesive industry, the addition of hollow microspheres can reduce the density of the adhesive, reduce the volume cost, improve the rheological property of the adhesive, improve the thixotropy and chemical corrosion resistance, and give the product better sound insulation, heat insulation, low heat conduction and dielectric properties, as well as better anti warping and anti cracking properties. Hollow glass beads are widely used in adhesives such as silicone, epoxy resin, acrylic acid, polyurethane, synthetic rubber, etc. In addition to the above, hollow glass beads have a very typical application for oilfield cementing, which is also the field with the largest consumption for a long time. The use of oilfield cementing includes low-density drilling fluid and cementing cement.

The low-density drilling fluid added with hollow glass beads not only has higher chemical stability and excellent fluidity, but also has better lubrication effect. It can reduce friction during drilling, extend the service life of drill pipe, drill bit and other equipment, and greatly improve the drilling speed and operating efficiency. The addition of hollow glass beads in cementing cement gives the product the characteristics of low density, high strength and easy flow. It is one of the main ways to solve the problem of low leakage and low return of cement slurry in low pressure and leaky wells. It can effectively control the water loss rate and prevent pollution. The 24h compressive strength can reach more than 15MPa, and can improve the cementing quality and extend the life of oil wells.

The physical characteristics of HG hollow glass microspheres lead to the following advantages:

1. The alkali lime borosilicate component of the glass microsphere makes its chemical property stable and inert, so that it can be safely used as a filler or additive without worrying about its reaction with the substrate or other substances, and can withstand other chemical corrosion except strong alkali.

2. The perfect sphericity endows it with excellent isotropic consistency, so that it will not warp and shrink due to stress inconsistency after processing.

3. The hollow glass microsphere is a small round ball. In the liquid, it acts like a miniature ball bearing, and has better fluidity than the fillings of sheet, needle or irregular shape. The resulting microsphere effect reduces the viscosity of the mixture, and the filling performance is naturally excellent; Good processing performance can improve the production efficiency by 10%~20%.

4. The perfect sphericity makes it have a small specific surface area of Z, so its oil absorption is low. Compared with the conventional filler calcium carbonate, the oil absorption rate/amount of hollow glass microspheres is much lower. The oil absorption rate of different models of products per 100g is between 7 and 40mg, while the oil absorption rate of light calcium carbonate per 100g is as high as 120 to 130mg, and that of heavy calcium carbonate is as high as 50 to 60mg. The amount of resin is reduced. At the same time, because it can increase the fluidity of resin, the resin is processed only as a base material rather than a filler, thus reducing the amount of resin.

5. Due to the particle size distribution of glass microspheres, small microspheres fill the pores of large microspheres, thus increasing their solid content. At the same time, their volatilization is very low, which reduces VOC

6. The color is white, so it has good color compatibility.

7. Its low true density and strong compressive strength result in its high compressive strength density ratio, which makes it not only play the role of filler or additive with reduced density, but also have a good survival rate and stability in the processing process in some applications requiring high compressive strength, such as extrusion, die or petroleum industry

8. The particle size is small, which will not reduce its toughness when mixed with resin for processing.

9: The interior of the hollow glass microsphere is a vacuum thin gas. Two different materials have different densities and thermal conductivity, so it has the characteristics of sound insulation, heat insulation and low thermal conductivity. It is an excellent filler for various heat insulation and sound insulation products. The thermal insulation properties of the microspheres can also be used to protect the products from thermal shock caused by alternate changes between hot and cold conditions

10: The closed space ratio is very high. At the same time, the sphere is tight and perfect, and it is insoluble in water, which makes its application in water very stable. Water will not enter the interior of the sphere, so it does not cause the problem of density increase. At the same time, because it is insoluble in water, its application in water, such as yachts, rowing, etc., is also extremely stable.

11: Some tests have shown that hollow or low hardness fillers will absorb and digest the impact strength when impacted, so as to improve the impact resistance of materials. Therefore, as a filler, it can improve the physical and mechanical properties of plastic products. At the same time, the hardness and elastic modulus of the material can be greatly increased, and the stiffness and stress damping capacity can also be improved.

12: It can maintain its stability below 600 ℃, so it is stable in some applications requiring slightly higher temperature.

Summary of Process
Feed material may be glass frit, other dry particles or solutions containing the forming components
Compositions are typically soda lime silicates, sodium borosilicates, etc.
Feed must contain a blowing agent
A blowing agent is a material that decomposes and releases gas at elevated temperature
Commonly sulfur-containing compounds
Feed material is introduced into a flame at elevated temperatures (~1100-1400°C)
Gas released by the decomposition of the blowing agent causes particles or droplets to expand to hollow glass microsphere.

SRNL has developed an experimental apparatus for forming HGMs based on this technique.

Particles may enter the flame by:
Falling downward due to the force of gravity
An updraft may be used to control the residence time in the flame
Particles have a short residence time in the heated zone
Conducive to HGMs with smaller diameters
Ascending upward by a gaseous stream
Residence time in heated zone is longer
HGMs with larger diameters are produced

Feed is introduced at the bottom of the furnace
A hot, gaseous stream carries the feed upward
Residence time within the hot zone of the furnace is a function of:
Particle mass
Upward velocity of the gas stream
Residence time is critical – just enough time to form a “tough outer skin”
Hollow sphere must then be removed at the point of maximum expansion and moved through regions of progressively diminishing temperatures
“Outer skin” cools and solidifies providing mechanical strength
The cyclone separates the HGMs from the gases
HGMs are produced with diameters of ~10 – 350 μm

Feed is introduced at the top of the heating chamber by a vibratory funnel
A “fluidizing agent” may be added to the particles to improve dispersion
The particles are transported to the flame by a carrier gas
Carrier gas further disperses particles
Particles fall though the flame front where fusion occurs
HGMs are cooled and separated from the gas mixture by a cyclone
HGMs are produced with diameters less than 125 μm

1.Hollow glass microsphere itself is inert without pollution. As a continuous medium, low density drilling fluid with addition of hollow glass microspheres was incompressible, and all wells are uniform in density. Sludge cakes formed have good lubrication, reducing the risk of sticking. It is technically infeasible for drilling large deviated wells and horizontal wells since the recycled micro-foam and air drilling technology can not deliver MWD signal. However, hollow glass microspheres have an irreplaceable advantage for it can not affect the system signal.

2.Hollow glass microspheres has a good rolling performance, and it can increase the drilling rate, and significantly improve the drilling efficiency.

3.Drilling fluid with hollow glass microspheres has feature of high temperature resistance, high pressure resistance, stability, durability, and can be recycled.

4.With the increase of low middle pressure layer, low-density slurry cementing with hollow glass microspheres were adopted to consolidate the wells to prevent or reduce leakage, increase the cement top. It plays a significant role in increasing the exploration reserves, improving single well production, and effectively developing underground oil and gas resources so as to solve complex problems.

Storage and Handling
To help ensure ease of storage and handling while maintaining free flowing properties, Hollow glass microspheres have been made from

a chemically stable glass and are packaged in a heavy-duty polyethylene bag within a cardboard container.

Minimum storage conditions should be unopened cartons in an unheated warehouse.

Under high humidity conditions with an ambient temperature cycling over a wide range, moisture can be drawn into the bag as the tem-

perature drops and the air contracts. The result may be moisture condensation within the bag. Extended exposure to these conditions

may result in “caking” of the hollow glass microspheres to various degrees. To minimize the potential for “caking” and prolong

the storage life, the following suggestions are made:

1.Carefully re-tie open bags after use.

2.If the polyethylene bag is punctured during shipping or handling, use this bag as soon as possible, patch the hole, or insert the

contents into an undamaged bag.

3.During humid summer months, store in the driest, coolest space available.

4.If good storage conditions are unavailable, carry a minimum inventory, and process on a first in/first out basis.

Dusting problems that may occur while handling and processing can be minimized by the following procedures:

1.For eye protection wear chemical safety goggles. For respiratory system protection wear an appropriate NIOSH/ MSHA approved resp-

irator. (For additional information about personal protective equipment, refer to Material Safety Data Sheet.)

2.Use appropriate ventilation in the work area.

3.Pneumatic conveyor systems have been used successfully to transport hollow glass microspheres without dusting from shipping cont-

ainers to batch mixing equipment. Static eliminators should be used to help prevent static charges.

Diaphragm pumps have been used to successfully convey hollow glass microspheres. Vendors should be consulted for specific recommendat-

ions.

The high-performance hollow glass microspheres breakage may occur if the product is improperly processed. To minimize breakage, avoid

high shear processes such as high speed Cowles Dissolvers, point contact shear such as gear pumps or 3-roll mills, and processing pre-

ssures above the strength test pressure for each product.

Health and Safety Information

For product Health and Safety Information, refer to product label and Material Safety Data Sheet (MSDS) before using product.

The high-performance hollow glass microspheres, a kind of ultra-light inorganic non-metallic powder with hollow “ball-bearing” shapes, have been developed into a new type of high performance lightweight material and have been widely applied in recent years. It will be the main direction for new-type compound materials in the 21st century. Its true density is 0.15-0.60 g/cm3; particle size is 5-180μm，and the crush resistance is beyond 60Mpa; Due to its excellent advantages of light weight, bulk density, lower thermal conductivity, higher compressive strength, improved dispersion and liquidity, and excellent chemical stability, it can be used as filler in painting, rubber, plastics, FRP, artificial stone, putty, exploitation of oil and gas and other materials.

The high-performance hollow glass microspheres are alternatives to conventional fillers and additives, such as silica, calcium carbonate, talc, clay, etc., for many demanding applications. These low-density particles are used in a wide range of industries to reduce part weight, lower costs and enhance product properties.

The unique spherical shape of hollow glass microspheres offers a number of important benefits, including: higher filler loading, lower viscosity/improved flow and reduced shrinkage and warpage. It also helps the hollow glass microspheres blend readily into compounds and makes them adaptable to a variety of production processes including spraying, casting and molding.

The chemically stable soda-lime-borosilicate glass composition of hollow glass microspheres provides excellent water resistance to create more stable emulsions. They are also non-combustible and nonporous, so they do not absorb resin. And, their low alkalinity gives hollow glass microspheres compatibility with most resins, stable viscosity and long shelf life.
