Application field of high performance hollow glass beads

Application of Hollow Glass Beads in Thermal Insulation Coatings Industry (Waterproof Low Alkalinity Beads)

Glass beads have the smallest specific surface area and low oil absorption rate, which can greatly reduce the consumption of other production components in coatings.

The vitrified surface of glass beads is more resistant to chemical corrosion and reflects light. Therefore, the coating has the effects of anti-fouling, anti-corrosion, anti-ultraviolet, anti-yellowing and scratch resistance.

⊙ Tightly arranged hollow glass beads contain thin gas and have low thermal conductivity, so the coating has very good thermal insulation effect.

Hollow glass beads can effectively enhance the fluidity and leveling of coatings.

The gas contained in hollow glass beads has good cold and hot shrinkage resistance, thus enhancing the elasticity of the coating and greatly reducing the cracking and peeling of the coating caused by thermal expansion and cold contraction.

⊙ Under the premise of high filling amount, the viscosity of the coating does not increase obviously, so the amount of solvent can be reduced, the emission of toxic gases during the use of the coating can be reduced, and the VOC index can be effectively reduced.

Suggestions for use:

Generally, the addition amount is 8-20% of the total weight.

The following adding methods are suggested: Add at last.

Finally, hollow glass beads are added and dispersed by a low-speed and low-shear mixing device. Because the microspheres have good spherical fluidity, low friction and easy dispersion, they can be completely wetted in a short time, and the stirring time can be slightly extended to achieve uniform dispersion.

Hollow glass beads are chemically inert and nontoxic, but they are extremely light, so special attention should be paid when adding them. We suggest the step-by-step addition method, that is, the amount of each addition is 1/2 of the remaining microspheres, which can prevent the microspheres from floating in the air and make the dispersion more complete. Hollow glass beads are used to fill UHMWPE materials, which can not only be used as solid lubricant to improve processing fluidity, but also modify the comprehensive mechanical properties of UHMWPE materials and improve their strength and wear resistance.

Hollow glass beads improve the tensile strength, impact strength, hardness and other mechanical properties of nylon 6, and can prevent the aging of materials caused by light and heat. With the increase of glass bead content, the Martin heat resistance temperature of the material increases. Used to produce bearings, cameras, furniture accessories, etc.

⊙ Using hollow glass beads to fill rigid PVC to produce profiled materials, pipes and plates can make the materials have good dimensional stability, improve rigidity and heat resistance, and improve production efficiency;

⊙ Filling ABS can improve the dimensional stability of materials, reduce shrinkage, improve compressive strength and flexural modulus, and improve surface coating performance, which can be widely used in the production of TV housings, automotive plastic parts, audio equipment and household appliances;

Filling epoxy resin can reduce the viscosity of materials and improve physical and mechanical properties, and can be used to produce composite foam plastics, deep-sea submarines, lifeboats and so on.

⊙ Filling unsaturated polyester can reduce the shrinkage and water absorption of materials, improve the wear resistance, have fewer cavities when laminating and coating, and can produce FRP products, polishing wheels, tools, etc.

Glass bead rubber is a good high-pressure and wide-band sound-absorbing material, and the target made of it has many practical advantages: it is easy to make a zero-buoyancy target, so it is suitable for making a towed target; Good flexibility can make the target easy to scroll and expand.

Applicable technology: except hand paste technology and extrusion molding technology, it can be applied.

Application of hollow glass beads in putty

Compared with ordinary putty, this new type of hollow glass bead putty has the following advantages:

Easy to prepare and produce, hollow glass beads can be well mixed by using a simple low-speed mixer, and the finished product is light in weight and large in relative volume.

Compared with ordinary putty, the new putty can replace 10 ~ 20% of talcum powder, calcium carbonate and bentonite with 5% of hollow glass beads, and its volume is increased by 15 ~ 25% compared with ordinary putty, saving about 8% of resin.

The oil absorption rate of hollow glass beads is much less than that of common fillers such as talcum powder, which can significantly reduce the viscosity.

⊙ The putty produced by hollow glass beads is easy to polish; Time-saving, labor-saving and labor-saving.

Application of Hollow Glass Beads in Artificial Marble Products

Adding hollow glass beads can reduce the product weight, smooth and beautiful appearance and reduce the cost.

1. Improve heat resistance

2. Lose weight by 20%-35%

3. Easier processing (drilling, sawing and grinding)

4. Easy polishing, high surface gloss and reduced tool wear.

5. Reduce packaging and transportation costs.

6. Improve production efficiency through faster mold turnover.

7. Anti-shrinkage, anti-warping, improve anti-cracking ability and reduce product breakage rate.

8. Reduce the amount of catalyst

Artificial wood filled with hollow glass beads can provide excellent quality assurance for manufacturing furniture parts, decorations and sculptures. The density of the product can be adjusted by adding different proportions of hollow glass beads to the original formula.

The oil absorption rate of hollow glass beads is much lower than that of ordinary fillers such as calcium carbonate, which can significantly reduce the viscosity.

Compared with traditional mineral additives, hollow glass beads have better fluidity and are suitable for manufacturing large thin plates. The materials added with hollow glass beads are easier to nail, which changes the common phenomenon of cracking of artificial wood with traditional formula after nailing.

Mixing of hollow glass beads;

The filling amount of hollow glass beads is generally between 5% and 20%. Hollow glass beads are easy to mix with resin, so it is generally recommended to add hollow glass beads in the final stage of mixing, and the stirring speed should be slow. If a high-pressure pump must be used, it must be determined in advance whether the strength of hollow glass beads meets the requirements.

Note: The mixing mode of hollow glass beads is also an important factor. We strongly suggest that the mixing speed of adding hollow glass beads should be lower than 100 rpm. Fly ash hollow floating beads are often used as lightening agent when preparing low-density cement slurry for oil and gas field cementing. However, due to the increasing shortage of these raw materials, low compressive strength, unstable performance of low-density cement slurry for cementing and poor cementing quality, it is easy to cause a series of problems such as cementing leakage. High-performance hollow glass microspheres of Sinosteel are composed of alkali lime and borosilicate ultra-light materials, which are rigid spheres and do not deform when heated. The ultra-low density cement paste prepared with this color reducer has good fluidity, viscosity and low water loss, and obviously improves the compressive and flexural properties of the cement paste after curing, and also improves the thermal stability and durability of the cement paste. The density of cement slurry prepared by mixing with cement is 0.90 ~ 1.45g/cm3. Cementing quality is better than fly ash hollow floating beads.
