Improve liquidity
Because the hollow beads behave like tiny bearing balls, they can easily roll with each other. This can help improve the fluidity of many materials added with hollow beads and make it easier to form final parts with complex geometry.
Higher volume addition
Because they can reduce the amount of resin, hollow beads can also achieve higher filler filling at the same viscosity. This may mean that less solvent is required to maintain operable viscosity, thereby reducing shrinkage and significantly reducing weight in some applications. For hydrocarbon solvent systems, this may result in a relatively low VOC system.
Cost effectiveness
The space occupied by lightweight hollow beads is 20 times larger than that of typical mineral filler with equal weight. This means that hollow beads can be a cost-effective choice in many applications when you consider the cost per unit volume rather than the price per pound, especially when you consider the possible enhancements of hollow bead technology.
Performance enhancement
Hollow beads provide performance and processing advantages far beyond lightweight. The inherent characteristics of these beads provide many unique potential enhancement tools to help you meet the characteristics and expand the design freedom in various applications.
CCL plate
High frequency transparent powder is a kind of hollow mullite hollow powder with stable chemical properties. Applied to high-frequency and high-speed PCB board, it can effectively reduce the dielectric constant and dielectric loss angle of resin / plastic, reduce the overall weight, improve dimensional stability, improve processing performance and enhance surface strength. High frequency transparent powder has different particle size, strength and density. All of them have been surface treated and can match most of the resin / plastic systems on the market. At the same time, we can optimize according to the customer's application requirements, so that customers can achieve the ideal attribute balance.
Modified plastics
5g high-frequency and high-speed transmission makes low dielectric constant modified plastics a new modification trend. The dielectric constant of the modified plastic has a great impact on the signal transmission speed, signal delay and signal loss of 5g communication millimeter wave. Reducing the dielectric constant of the modified plastic is conducive to improving the signal transmission speed, reducing the signal delay and reducing the signal loss of the intelligent terminal. The introduction of nano or micron hollow beads into modified plastics can significantly reduce the dielectric constant of the material; Realize product lightweight and reduce cost; Improve the processability of materials; Improve the mechanical properties of materials; Improve the flame retardant and thermal insulation properties of the materials; It can be added by mixing, stirring and side feeding without changing the existing production mode.
Lightweight materials
The manufacture of synthetic foam composites is also one of the main uses of hollow microspheres. The artificial foam prepared by mixing hollow microspheres into liquid resin has the characteristics of light weight, high compressive strength and fire resistance. At present, it has been used in deep-sea exploration, offshore drilling, sealing of marine machinery, buoyancy materials for marine residence, etc.
As a new structural material, plastic is widely used because of its convenient molding and excellent performance. However, plastics are expensive, low mechanical strength, sensitive to temperature, prone to creep, and lack of rigidity and hardness. Therefore, it is necessary to reduce the raw material cost of plastic products and improve their friction resistance, heat resistance, dimensional stability and rigidity. Usually, one or more inorganic fillers need to be added to the resin for reinforcement. Hollow beads are round and smooth in shape, with little aggregation force between particles. They are easy to disperse when filled into plastic and have good processing rheology. They are an excellent inorganic filler.
Coating, paint
Because hollow beads have the characteristics of insulation, flame retardant, high and low temperature resistance, anti-corrosion, fire prevention, thermal insulation, self-lubrication, good fluidity, large specific surface area and small particle size. Therefore, it can be widely used in various high-grade inks, high-temperature insulation paint, high wear-resistant and anti-corrosion paint, high-grade furniture paint, ship anti-corrosion paint, high-grade spraying paint for automobile, external paint for various mechanical equipment, internal and external wall paint for construction and various putty.
rubber
Hollow beads are used as the filling material of rubber. The filling of rubber by beads can play the role of light weight, wear resistance, heat insulation, corrosion resistance, flame retardant and moisture-proof. Because its compressive strength is up to 7000kg / cm2, it can significantly enhance the wear resistance of rubber tires and rubber soles, so as to prolong the service life.
Abrasives, abrasives
The abrasive tool is filled with special hollow beads, which is an excellent pore forming agent for consolidated abrasive tools. Filling in the consolidated abrasive tool can not only play an important role in making holes and teeth, but also reduce the weight of the abrasive tool. When the abrasive tool works, the cooling and grinding efficiency of the abrasive tool are greatly improved. Compared with ordinary fillers of the same weight, lightweight high-performance hollow beads can occupy more volume. This means that high-performance hollow beads can reduce the cost when considering the cost per unit volume rather than the cost per unit weight.
Drug carrier, catalyst carrier
In recent years, hollow nanoparticles have attracted more and more interest due to their importance in various scientific and technological fields such as drug delivery, minimal carrier of catalysts, biomarkers, optical resonance, catalysis, magnetism, ceramics and pigments. It is recognized that compared with conventional solid spheres, nano hollow spheres with mesoporous shell show more advantages in material diffusion and material transport.
