Sandblast Glass Beads 150#

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

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.

High Strength Glass Beads (for Blasting)
With compressed air as implicit power, this product is made by sprinkling beads under high speed and pressure on the surface of workpiece for peening and polishing.

Other purposes of the products are as follows:
1. Clear diverse moulds of impact forging, forging, glass, rubber and plastic, metal casting and extrusion.
2. Eliminate tensile stress, increase fatigue life and enhance stress corrosion resistance. For example, aircraft engine turbo, vane, shaft, undercarriage, diversified springs and gears, etc.
3. Clean and remove slitter edge and burr on the circuit plate and plastic-sealed geminate transistors before stannum soldering
4. Remove stems in the piston and cylinder and provide bright and half-lackluster surface for medical mechanical instruments and automobile parts
5. Clear electromotor and such parts as loop, electric brush and rotor of during heavy repair
6. Clean up and remove burr of metal tube and precisely-melten non-ferrous metal tube. Be used for peening aggrandizement and polishing of textile machinery parts.
