glass beads from the boron-silicate raw materials processed by high-tech, particle size of 10-250 microns, wall thickness 1-2 microns. The product has a light weight, low thermal conductivity, high strength, good chemical stability, etc., on its surface specially treated with a pro-oil-water-repellent properties, very easy to disperse in organic materials system.
Glass beads used in aerospace, machinery, rust, urban traffic road crossing, Jin Ting lines, double yellow lines at night reflective, and traffic signs at night reflective devices.
Hollow glass beads have been widely used in artificial agate, marble, glass fiber reinforced plastic bowling line materials and high-grade thermal insulation coatings, has significantly reduced product weight and good thermal insulation effect.
Hollow glass bead-performance civilian emulsion explosive sensitizing agent, can significantly increase the detonation properties of emulsion explosives to extend the storage period. In addition, the hollow glass beads can also be used putty to increase volume, improve the polishing performance, increase performance, acid and alkali.
Components SiO2, Al2O3 and other characteristics of a gray powder characteristics:
1. Inexpensive;
2. Reinforced plastic toughness, does not diminish its own stiffness;
3. A high melting point can be improved by filling the flame-retardant properties and Vicat softening point;
4. Electrical insulation, and can be used to fill the high insulating polymer;
5. To increase the liquidity of being filled with material to increase the performance of plastics processing, while improving leveling the surface of engineering plastics, glass fiber reinforced to solve the surface problems;
6. Can effectively reduce the shrinkage of filler;
7. The real density 1.78g/cm3 (bulk density 1.12g/cm3) relative to the glass fiber, calcium carbonate, talc filled engineering plastics, can obviously achieve the effect of weight loss;
8. Resistant to corrosion; add the amount of: Air Micro Inc. PP and the PA generally recommended dosage is to add 30-40%, HIPS, PBT added amount is generally 7-15%, ABS dosage is generally 5-7% Usage: In the conventional use of engineering plastics, hollow beads in high-speed mixer using silane coupling agent KH-550 modified, may be properly mixed with the plastic pellets mixed directly in the twin-screw extrusion machine pumping tablets.
