8 Production Our glass beads in the 0.05 mm and 5 mm size ranges, are produced through a special thermal rounding process. The particularity of this way of production is that it needs much less energy than other traditional melting processes. Main advantages homogenous and smooth surface small proportion of airbubbles high roundness and elasticity wide assortment of sizes, narrow sizeranges free from foreign particles, glass fragments and other impurities low risk of bead breakage Applications shotblasting beads to smooth out the surface SiLibeads Type S SiLibeads Type S are optimal for the use as grinding and dispersing media in horizontal and vertical pearl mills for the wet grinding of lacks, pigments, dyestuff, ink, agrochemicals and minerals, as filling agent for chemicals, paper and plastic. Particle sizes less than 10 can be obtained. The low wear rate of the agitator disc and of the grinding chamber allows to reduce the production costs. The advantage that it brings to the costbenefit aspect is evident. pearl mill filled with grinding beads metal surface treatment (mechanical plating) Further applications micro glass beads for the surface coating of metal,plastic, ceramic and wood filling material for the modification of the physical properties of thermoplast and duroplast in diameters > 0,6 mm, as reflection beads for roadmarking, specially to improve the visibility at night in case of rain reflection beads for road marking polishing agent for optical and interocular lenses. For the optimal use of our glass beads, we recommend to follow carefully the instructions for use.
