To solve industrial problems
Application of hollow glass microspheres in paint
Hollow glass microspheres have the smallest surface area and low oil absorption rate, can significantly reduce the consumption of other components in paint.
The vitrified surface of glass microspheres can realize the chemical corrosion resistant, and reflexaction on light. Therefore, the paint can prevent from fouling, corrosion, UV, yellowing and scratching etc.
Thin gas inside the hollow glass microspheres with compact arrangement, makes low thermal conductivity, so that paint coating has a very good effect on heat insulation.
Hollow glass microspheres can effectively enhance the fluidity and smoothness of coating.
Hollow glass microspheres contain gas inside, so it has a good contractility resistance to hot and cold, thus enhancing the flexibility of coating, greatly reducing the cracking and peeling of the coating due to thermal expansion and contraction.
On premise of high filling level, the viscosity of paint will not be significantly increased, thus reducing the usage of solvents. It can reduce toxic gas emissions in the process of painting, and VOC indicator can be effectively reduced.
Dosage recommendation:The addition is normally about 10-20% of the total weight. Adding methods are proposed as follows: Last step. The hollow glass microspheres are proposed to add at the last step, and dispersed with low-speed, low shearing force mixing equipment. Due to its good liquidity,small friction, so it willeasily dispersed into mixture to completely keep wet within a short time. Through slightly extending mixing time can achieve uniform dispersion. Hollow glass microspheres are inert and non-toxic. Due to its light weight, attention should be specially paid when adding. We recommend adding the microspheres by step, that is, the addition quantity is 1 / 2 of the remaining beads each time. It can well avoid the microspheres floating into the air and make it disperse even more completely.

Filled into epoxy resin，it can reduce the material’s viscosity and improve the mechanical properties. So it can be used in production of composite foam plastic, deep-sea submarine, lifeboat, etc.
Filled into unsaturated polyester. It decreases the shrinkage and water absorption of materials, increase its wear resistance. Meanwhile, less space is produced when laminated and coated. So it can be applied in production of FRP products etc.
Application of hollow glass microspheres in Putty
Compared with the traditional putty, the new type one adding with HGS owns the advantages as follows:
Easy preparation and production, the HGS can be well mixed by a simple low-speed mixer. Its product has a feature of light weight and large volume.
Compared with the ordinary putty, new putty with 5% of hollow glass microspheres, can replace 10 ~ 20% of talc, calcium carbonate, bentonite. Its volume can also be increased 15~25% than that of ordinary putty,and saving resin about 8%.
The oil absorption rate of HGS is much less than that of talc and other fillers. So it has a significantly lower viscosity.
Putty with HGS can be easily polished with advantages of time saving, labor-saving and dust reduction.

The wood materials with addition of hollow glass microspheres are more easily nailed. It can avoid the phenomenon of cracking existing in the traditional formula of artificial wood in general after nailing.
Hollow glass microspheres mixture:
The filling quantity of hollow glass microsphere generally is between 5% -20%. It can be easily mixed with resin, and is proposed to be added at the final stages of mixing with a slower mixing speed. If the high-pressure pump must be required, it should be determined that whether the strength of hollow glass microspheres can meet the requirement in advance.
Note: The mixture method of hollow glass microspheres is also important, we strongly recommend that the mixing speed of adding hollow glass microspheres should be less than 100 r / min.

Application of hollow glass microspheres in the exploitation of oil and gas fields
Hollow glass microspheres 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.
Hollow glass microspheres have a good rolling performance, and it can increase the drilling rate, and significantly improve the drilling effectively.
