Abrasive blasting is simply another industry term for sandblasting. It is the process of propelling a stream of abrasive material against a surface under high pressure. Sandblasting is commonly used to smooth and clean a surface. Or completely reshape the surface; as well as removing any unwanted rust or debris.
However, there are a variety of materials you can use to achieve your desired effect. Some materials are highly abrasive; others are milder. This week Markwell Peck, sandblasters in London, are here to discuss which type of abrasive is best; depending on the job.
If you are looking into giving an object a new lease of life; then sandblasting with glass beads may be the best choice for you. Being one of the most environmentally friendly and recyclable options. It is not as aggressive compared to other materials. This makes glass beads ideal for stainless steel applications, achieving a softer; brighter finish.
Aluminium oxide is one of the most aggressive medias when it comes to sandblasting. Sharp and angular aluminium oxide can deeply etch materials. It is commonly used for the preparation of surfaces prior to painting. This would be the ideal material if you are in the industrial industry due to its superior strength. It is also a suitable option for almost any type of surface: marble; granite; glass and steel.
If you’re trying to undertake a sandblasting job on a budget then steel shot may be the best option for you due to its toughness and recyclability. It is often used to remove any kind of contaminants as well as hardening applications.
Silicon carbide is the hardest abrasive available when it comes to sandblasting, meaning it’s the best media choice for any challenging applications. Its primary use ranges from lapping, polishing, glass etching and heavy duty blast cutting applications. It is ideally suited for cutting stone, glass and other hard surfaces.
