Ceramic bead

タイトルまたは説明

⊙Ceramic bead is produced by electric and thermal fusion of oxides, the internal structure is made up of a crystalline ceramic phase, bonded by an amorphous silica phase, resulting in high impact properties coupled with good hardness. They ensure excellent working conditions thanks to their low dust emission, round shape, smooth surface and high strength. Chemically inert, they do not contaminate the treated substrates. They are recognized as highly performing and cost effective industrial solutions for sand blasting processes and widely utilized in surface treatment of components including: castings, surface cleaning of rubber and plastic molds, boiler and heat exchanger parts, etc. Also used for blasting particularly in the aerospace industry. Ceramic bead offers several advantages over traditional media like steel shot and glass beads. It can achieve blasting intensities similar to those obtainable with steel shot, but with a resulting lower surface roughness. Ceramic bead is also applied in wherever steel shot cannot achieve due to potential ferrous contamination from the steel media. Its high density enables blasting intensities equivalent to those obtainable with glass beads, to be obtained at a greatly reduced abrasive velocity. This feature results in reduction in sand waste and the improvement of the working environment and better operator visibility. Its narrow particle size distribution coupled with low breakdown rates, enables repeatable, consistent result to be achieved. Thus ceramic bead is an ideal choice when selecting a media for blasting applications. Typical application as sand blasting media:  Foundry: - Deburring of thin and fragile parts - Finishing of parts magnesium and other metal alloys - Cleaning of molds, core boxes and tools - Treatment of hard0to –reach zones  Cryogenic deburring of plastic parts, compacting of plasma coating, cleaning, surface preparation of mechanical parts, aluminum cylinder heads, medical prosthesis eyeglass frames, surgical instruments.  Automotive industry: - Scale-removal: universal joints, welds - Polishing or repair of surface: alloy wheels - Refurbishment: alternators - Shot peening: springs, pinion gears.  Vessel construction: specially for the stainless steel and aluminum components and assemblies for the textile, food, nuclear, chemical and other industries, the bead are used for: - Cleaning and finishing of surfaces - Stress-relieving of welds - - Shot peening of reactor vessel to prevent and reduce the spread of cracks as well as stress corrosion. - Aircraft motor, paint removing  Glass making, tire-making and extrusion of lightweight extrusion alloys of plastic. Beads also are used to clean molds, dies and tools.
