Sandblast Glass Beads 20#

short description:

Glass beads for sandblasting has the features of chemical stability, high mechanical intensity and hardness. They can be blasted onto the object surface with compressed air and can be used on compress glass, rubber, plastic, moulds with metal casting or compressing. The jetting balls would help reduce elasticity of the surface materials and increase wearing capacity.

Product Function

Sandblasting glass bead with the characteristics of certain mechanical hardness, strength, and strong chemical stability. They are manufactured from soda lime silica glass and can be used as blasting materials to remove many different types of surface imperfections, including metal cleaning, surface finishing, peening, deburring. It lowers visibility of any potential damage, scratches, smaller defects after welding, grinding, or spot welding and raises product´s corrosion resistance and help to increasing wearing capacity.

Glass bead blasting is suitable not only for final treatment of a new product or as a pre-treatment before subsequent chemical processes (electroforming, anodic oxidation), it also breathe new life into older objects, be it motor components, art and decorative objects or interior accessories.

Blasting with Glass Beads under pressure will maintain the products without dimensional change, without contamination and without overstressing. It produces a consistent metallurgical clean surface finish. Conventional Blasting Materials such as Aluminium Oxide, Sand, Steel Shots will either leave a Chemical Film on the blasted surface or have cutting action. Glass beads generally smaller and lighter than other media and can be used to peen into sharp radii of threads and delicate parts where very low intensities are required. Shot Blasting with the Glass Beads completely prepares metal surface for any type of coating on it such as painting, plating enameling or glass lining.Glass beads can be safe compared to other blast medias. Additional benefits of glass bead blasting include that you can use them for a few cycles before they no longer clean a surface. It is common for glass bead media to last 4 – 6 cycles before needing to be replaced. Finally, glass beads can be used in a suction or pressure blast cabinet. This makes it versatile and can help offer a blast cleaning media that keeps your blast cabinet costs down.

Glass Beads used as blasting materials are with the features of clearness, hardness and toughness. They are suitable for cleaning and polishing burrs and dirt on various mold surfaces so that the processed articles have a good finish and prolong their service life. Its recyclability makes it an economical choice.The chemical nature of the glass beads is inert and non-toxic, during use, no iron or other harmful substances remain on the surface of the workpiece, nor will it adversely affect the surrounding environment. The roundness of the smooth surface makes it no scratch damage to the mechanical precision of the workpiece during the process of sandblasting. One unique application for glass bead blasting is peening, which helps the metal better resist fatigue and cracking from stress corrosion. One study found that it can increase fatigue strength by about 17.14%. It gives you an attractive satin finish while increasing the durability of the product.
