Hollow glass sphere is widely used in glass fiber reinforced plastic products, syntactic foam, artificial marble, compound wood, sound insulation heat preservation material, atomic ash, deep-sea buoyancy, bowling, low-density cement, sealing material, lightweight, resin handicraft, mural hanging frame, wall plate sandwich layer structure lightweight packaging materials, electronic industry, absorbing material, lightweight concrete, emulsion explosive, etc.
The larger use of hollow glass beads is artificial marble.
In the United States, many manufacturers are using this filler, which has the following advantages:
Improve the impact performance, the correct formula manufacturing products its performance is higher than the artificial marble association requirements;
Improve texture layout and color continuity, making products more beautiful and dazzling;
Reduce the curing time, with a faster mold turnover speed; Improve impact strength, improve anti-cracking ability, reduce the damage rate of products;
Improved machinability and reduced time for flailing, cutting, drilling and grinding.
Reduce wear and tear of post-treatment tools.
Improve the tinting performance of light colors while reducing the amount of TiO2 (although sometimes darker colors need to be mixed in)
Its light weight makes it easier to carry and install, and also reduces transportation costs.
Hollow glass beads are used to fill UHMWPE materials, which not only acts as a solid lubricant to improve the fluidity of processing, but also can modify the comprehensive mechanical properties of UHMWPE materials to improve their strength and wear resistance. The tensile strength, impact strength, hardness and other mechanical properties of nylon 6 with hollow glass beads can be improved, and the material aging caused by light and heat can be prevented. With the increase of glass bead content, the Martin temperature of the material increases.
Used for the production of bearings, cameras, furniture accessories, etc. Filling hard PVC with hollow glass beads to produce profiles, pipes and plates can make the material have good dimensional stability, improve rigidity and heat resistance temperature, and improve production efficiency; Fill ABS, can improve the stability of material size, reduce shrinkage rate, improve compressive strength and bending modulus, and improve the performance of paint on the surface, can be widely used in the production of TV casing, automobile plastic parts, audio equipment, household appliances; Filled with epoxy resin, can reduce the material viscosity, improve the physical and mechanical properties, can be used to produce composite foam plastics, deep-sea submarines, lifeboats, etc. Fill unsaturated polyester, can make the material shrinkage and water absorption rate decreased, improve wear resistance, and in the lamination and coating when the hole is less, can produce FRP products, polishing wheel, tools and so on;
Glass beads have the smallest specific surface area and low oil absorption rate, which can greatly reduce the use of other production components in the coating. The vitrified surface of glass beads is more resistant to chemical corrosion and has a reflection effect on light. Therefore, the coating has anti-fouling, anti-corrosion, anti-ultraviolet, anti-yellowing and anti-scraping effect. The tightly arranged hollow glass beads contain thin gas inside, and their thermal conductivity is low, so the coating has a very good heat insulation effect. Hollow glass beads can effectively enhance the flow and leveling of the coating. Hollow glass beads contain gas with good heat and cold shrinkage resistance, so as to enhance the elasticity of the coating, greatly reduce the coating due to thermal expansion and contraction caused by cracking and falling off. Below the premise that fills in high quantity, the viscosity of coating increases not apparent, because this dissolvent usage amount can reduce, can reduce coating to be in use the discharge of toxic gas in the process, reduce VOC index effectively.
Recommended use: Generally add 10-20% of the total weight. The hollow glass beads in the last to add, the use of low speed, low shear force of the mixing equipment dispersion, because the spherical flow of the beads is good, the friction between the small, so it is easy to disperse, in a short time can be wet completely, slightly extend the mixing time to achieve uniform dispersion. Hollow glass microbeads are chemically inert and non-toxic, but because they are extremely light, special care needs to be taken when added. We suggest to adopt the step adding method, that is, the amount of each time is 1/2 of the remaining beads, gradually adding, so as to avoid the beads floating into the air and make the dispersion more complete.
Vehicle chassis armor
Professional chassis armor is to spray a special elastic gum material on the chassis of the car, completely wrap the chassis and the part above the wheel, and form a layer of corrosion resistant chassis protection layer with certain strength after its natural consolidation. Added hollow glass beads chassis paint characteristics: glass beads vitrified surface is more resistant to chemical corrosion, therefore, paint coating has anti-fouling, anti-corrosion, anti-yellowing and anti-scraping effect. If filled with appropriate proportion, the spherical structure of the particle impact force and stress has a good dispersion effect, added to the coating can well improve the impact resistance of the coating film, but also reduce the coating due to thermal expansion and contraction of stress cracking. The toughness, impact resistance and surface hardness of the products are improved obviously. The particles are airtight hollow spheres, which are added into the coating to form a lot of microcosmic independent adiabatic cavities, thus greatly improving the insulation of the film to heat and sound, and playing a good role in heat insulation and noise reduction.
