Application of Hollow Glass Microspheres in the Thermal Insulation Coating Industry (Waterproof, Low Alkali Microspheres)
Glass microspheres have the smallest specific surface area and low oil absorption, which can greatly reduce the use of other production components in coatings.
The vitrified surface of glass microspheres is more resistant to chemical corrosion and has a reflective effect on light. Therefore, paint coatings have anti fouling, anti corrosion, anti UV, anti yellowing, and anti scratch effects.
The tightly arranged hollow glass microspheres contain thin gas inside, and their thermal conductivity is low, so the coating has a very good thermal insulation effect.
Hollow glass microspheres can effectively enhance the flow and leveling properties of coatings.
⊙ The gas contained in the hollow glass bead has good resistance to cold and heat shrinkage, thus enhancing the elasticity of the coating and greatly reducing the cracking and falling off of the coating due to Thermal expansion.
Under the premise of high filling amount, the viscosity of the coating does not increase significantly, so the use of solvents can be reduced, which can reduce the emission of toxic gases during the use of the coating and effectively reduce the VOC index.
Usage suggestions:
The general addition amount is 8-20% of the total weight
Suggest the following addition method: Finally, add.
Place the hollow glass microspheres at the end and add them, using a low speed and low shear mixing equipment to disperse them. Because the microspheres have good spherical fluidity and little friction between them, they are easily dispersed and can be completely wet in a short period of time. Simply extend the mixing time to achieve uniform dispersion.
Hollow glass microspheres are chemically inert and non-toxic, but due to their extreme lightness, special attention needs to be paid when adding them. We suggest adopting a step-by-step addition method, which means adding 1/2 of the remaining microspheres each time and gradually adding them. This can effectively prevent the microspheres from floating into the air and making the dispersion more complete. ⊙ Hollow glass microspheres are used for filling ultra-high molecular weight polyethylene materials, serving as a solid lubricant to improve processing flowability and modifying the comprehensive mechanical properties of ultra-high molecular weight polyethylene materials to improve their strength and wear resistance.

Mixing of hollow glass microspheres:

The filling amount of hollow glass microspheres is generally between 5% and 20%. Hollow glass microspheres are easily mixed with resin, and it is generally recommended to add hollow glass microspheres in the final stage of mixing at a slower stirring speed. If a high-pressure pump must be used, it is necessary to determine in advance whether the strength of the hollow glass microspheres meets the requirements.
Note: The mixing method of hollow glass microspheres is also an important factor, and we strongly recommend that the mixing speed of adding hollow glass microspheres should be less than 100 revolutions per minute. The preparation of low density cement slurry for oil and gas field cementing often uses fly ash hollow floating beads as a reducing agent. However, due to the increasingly scarce supply of these raw materials and low compressive strength, the current performance of low density cement slurry for cementing is unstable, the quality of cementing is poor, and it is easy to cause a series of problems such as cementing leakage. Zhonggang high-performance hollow glass beads are made of Soda lime and borosilicate ultra light materials. They are rigid spheres and do not deform when heated. The ultra-low density cement slurry prepared by this reducing agent has good flowability, viscosity, low water loss, and significantly improves the compressive and flexural properties of the solidified cement stone. At the same time, it also improves the thermal stability and durability of the cement stone. The cement slurry produced by mixing with cement has a density of 0.90~1.45g/cm3. The cementing quality is better than that of fly ash hollow floating beads.
