Processing method of the present invention: acceptable material is through after broken, screening, measuring, be mixed into admixtion, admixtion is molten into glass metal in melting furnaces, the melting furnaces forming part is equipped with the single hole platinum bushing, glass metal after the fusing goes out to form glass metal stream thigh from the bushing orifice flow, the stream thigh vertically falls in the sedimentator, the sedimentator high speed rotating, force glass metal to throw away and via Cheng Zhu behind the high-temperature zone by centrifugal force by the aperture on the sedimentator perisporium, collect this granulated glass sphere, and it is annealed, eliminate or reduce thermal stresses in the granulated glass sphere, promptly obtain granulated glass sphere of the present invention.
Granulated glass sphere in the present embodiment can be widely used on the different kinds of roads graticule because of its reflective high brightness, specific refractory power height, especially be applied on the airport runway mark line, people especially aviator had good warning function, especially under the lower situation of visibility meter, its effect is more obvious.
Embodiment two: this embodiment is that with embodiment one described a kind of difference that is used for the high-brightness glass bead of airport runway mark line the particle diameter of described granulated glass sphere is 600 ~ 2360 microns.
The present invention's granulated glass sphere particle diameter in the course of processing with the corresponding relation that sieves allowance (%) is: particle diameter is greater than 2360 microns, and the sieve allowance is 0%; Particle diameter is between 2000 ~ 2360 microns, and the sieve allowance is 0% ~ 10%; Particle diameter is between 1180 ~ 2000 microns, and the sieve allowance is 30% ~ 60%; Particle diameter is between 850 ~ 1180 microns, and the sieve allowance is 60% ~ 85%; Particle diameter is between 600 ~ 850 microns, and the sieve allowance is 95% ~ 100%; Particle diameter is less than 600 microns, and the sieve allowance is 0% ~ 5%.
Embodiment three: this embodiment is that with embodiment one or two described a kind of differences that are used for the high-brightness glass bead of airport runway mark line the specific refractory power of described granulated glass sphere is 1.91 ~ 1.98.
Embodiment four: this embodiment is that with embodiment three described a kind of differences that are used for the high-brightness glass bead of airport runway mark line described granulated glass sphere is made by 29 ~ 34 parts of titanium dioxide, 45 ~ 50 parts of barium oxide, 13 parts of silicon-dioxide, 1.5 parts of zinc oxide, 2 parts of boron oxides, 4 parts of calcium oxide and 0.5 part of aluminum oxide.
Embodiment five: this embodiment is that with embodiment three described a kind of differences that are used for the high-brightness glass bead of airport runway mark line described granulated glass sphere is made by 30 parts of titanium dioxide, 49 parts of barium oxide, 13 parts of silicon-dioxide, 1.5 parts of zinc oxide, 2 parts of boron oxides, 4 parts of calcium oxide and 0.5 part of aluminum oxide.
Laboratory report:
1, description of test:
Titanium dioxide, barium oxide, silicon-dioxide etc. all adopt analytical reagent in the experiment.Various raw materials according to certain proportioning, after weighing mixes, are melted in corundum crucible and insulation for some time, fused solution is poured into rapidly carried out quenching in the water, the glass sand that obtains obtains granulated glass sphere through roasting.Utilize German Lay speed particle diameter morphological analysis instrument to the particle diameter of granulated glass sphere with become the circle rate to analyze, utilize opticmicroscope carry out the devitrification of granulated glass sphere and granulated glass sphere the surface, observe inside.
This is tested, and proportionlity is defined as between each component: 27 ~ 40 parts of titanium dioxide, 40 ~ 51 parts of barium oxide, 12 ~ 14 parts of silicon-dioxide, 1.5 parts of zinc oxide, 2 parts of boron oxides, 4 parts of calcium oxide and 0.5 part of aluminum oxide are made.By changing the ratio of titanium dioxide, barium oxide, silicon-dioxide, determine the chemical constitution of glass formula in the experiment, record its specific refractory power.Experiment gained granulated glass sphere particle diameter scope is 600～2360 microns, and color and luster is: colourless or yellowish.Its experimental data sees the following form:
2, analyze and discuss:
When the specific refractory power of granulated glass sphere was 1.93, its focal length was just at spherome surface, and the retroreflecting performance of this kind granulated glass sphere is best, and is best to people's caution effect.The simple glass pearl is not enough to reach so high specific refractory power, and the existing method that improves specific refractory power is to add the high component ion of specific refractory power in the glass composition, as Pb
2+, Ba
2+, Bi
3+, Ti
4+, but because divalent lead has severe toxicity, and the glass scope that does not meet environmental requirement, Ti-Bi system is narrower, but its specific refractory power can only reach about 1.5, and specific refractory power is lower.Thereby the present invention selects TiO for use
2-BaO-SiO
2System is produced high-refraction glass bead.
The experiment proved that the prescription of granulated glass sphere of the present invention has reached 1.91 ~ 1.98 specific refractory power, specific refractory power is higher.
