A variety of media can be used as an abrasive for blasting, depending on the application and the substrate requiring treatment but, as regulations prohibit the use of silica sand, particularly due to its association with chronic health conditions, glass bead offers a viable and cost-effective alternative.
Gentle solution for treating sensitive surfaces
Glass bead is a commonly used abrasive media in blast cleaning. Depending on the size used and when used correctly, it can create an aesthetic, smooth finish, be used for NDT Blast Preparations or even to delicately provide a clean surface free from corrosion or contamination, without significantly impacting the shape or impinging into the surface that is being treated.
Long-lasting and Environmentally friendly
Being able to re-use a blast media is an important way to reduce costs, as well as helping to protect the environment. Glass bead can typically be recycled up to 6 times (subject to client approval) before their effectiveness reduces, lessening the need to renew the media with each surface treatment and cutting down the amount of waste that is generated.
The beads are typically manufactured from recycled glass and are inert, lowering your business’s carbon footprint.
Glass bead is safe for operatives
Unlike silica sand, glass bead does not contain silica, making it a safer alternative for blast operatives. With bead blasting, concerns over the long-term health effects, particularly on the respiratory system, are reduced. It is still important that the necessary PPE is worn to ensure the operatives are adequately protected.
Non-reactive with other chemicals
With glass beads being chemically inert, the process is safe to use with other materials, confident that a reaction will not occur. This means that glass bead blasting is a reliable and flexible solution in industrial situations.
