Sponge Blast Media – Choice And Use

Sponge Media Has A Unique Feature

This sponge media is of the hardness on the MOH scale 8

Dust Capture
Sponge media is normally used in an open blast process and in confined areas, high value sensitive areas such as the electronics command room in a submarine, sensitive areas of an aircraft or operations room, where time and duration costs can be significantly high.

Sponge captures the dust at the source of generation.
When the sponge media is propelled against a surface, the sponge flattens and exposes the abrasive which abrades or cleans the surface.  On its rebound, the sponge expands back to its original size causing a vacuum inside the sponge, which in turn captures the dust particles.  Sponge is recyclable and minimises waste generated during surface cleaning.  Unlike conventional hard abrasives which ricochet for distances far and wide, using up its retained energy, sponge media uses its energy upon contact, by flattening out.

Sponge

Benefits

  • Low dust – Contaminants are contained at the source, resulting in less dust to collect – although the operation isn’t entirely dust free, there is a much reduced need for dust suppression and extraction.
  • Surface preparation in confined environments.
  • Keeps sensitive equipment protected.
  • Recyclable.
  • Improvement in operator visibility, meaning less re-work.
  • Greater operator safety – low abrasive rebound and low dust.
  • Reduce down-time – other trades can work simultaneously.
  • Dry surface preparation.
  • Replace mechanical cleaning tools for faster and easier treatment of curved surfaces.
  • Removes non-visible salts from steel.
  • Depending on grade selected it creates a surface profile of 5 – 100 microns on steel.
  • Sponge provides dust containment and is able to perform as a dry process.
  •  Increased productivity and reduced down-time can be achieved because sponge allows confined spaces to be cleaned without affecting sensitive equipment.
