What is glass bead media?
Glass Beads are a round, spherical media that produce a softer and brighter finish angular medias. Glass Beads are used for blasting, peening, honing, cleaning, and light deburring.
What grit is glass bead media?
50 Micron 240 Grit. High quality blast media. Spherical bead shape. Ideal for surface texturing, cleaning, peening, etching, and deburring various surfaces.
What media do you use to etch glass?
The two most common blast medias you use in a blast cabinet for glass etching include glass beads and aluminum oxide. You typically want to select a higher grit number (120 or higher blast media which is a finer particle) as this will allow more control and better results etching.
How long does glass bead media last?
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.
Is coal slag good for sandblasting?
Coal slag is an abrasive blasting media that is created as a recycled byproduct of coal combustion in power plants. The slag forms unique angular shapes making it a perfect material for a variety of applications. Due to its physical properties, it is seen as an alternative to silica sand.
Can you reuse glass bead media?
Glass bead is not as aggressive as other blasting abrasives, making it a perfect choice for softer finishes. Many people prefer glass beads because they are environmentally friendly and are free from silica. These beads can also be reused many times, saving your team time and money.
Why use glass bead media?
Glass bead media, when used properly, can create a wide range of easily reproduced and unique surface finishes. Using glass beads can help improve the tensile strength in metal parts and reduce stress corrosion cracking.
What size glass bead blasting media do I Need?
While glass bead blast media comes in a variety of sizes ranging from 40 – 325 mesh sizes there are mesh sizes that are more common. Common mesh sizes for glass bead blasting include 50-70, 60 -80, 70-100, 120 – 200. The fastest cleaning glass bead is typically 60-100 mesh.
Why do fine beads consume more media than coarse beads?
Finally, fine beads also consumed slower at the same pressure as coarse beads. For all sizes of glass beads: bead size, angle of the blast nozzle, shape of the workpiece, distance from the workpiece, air pressure all dramatically affect the ultimate surface preparation and media consumption.
Is glass bead blast media better than steel grit?
Finally, compared to steel grit or shot and aluminum oxide glass bead blast media is only reusable a few times compared to numerous times with steel blast medias. Knowing the benefits of glass beads, it is also good to know the common uses for glass bead blasting.
