The Benefits of using SodaBlasting:
Soda is unique and can be utilised on certain substrates where currently no alternative non-destructive method of cleaning can be used; for example fibreglass or aluminium frames and wheel rims. Even delicate substrates can be safely cleaned by an experienced operator.
Soda does not result in heat build-up in the substrate, which is a common problem with sandblasting; heat transfer to the substrate can contribute to warping, metal fatugue and profiling.
Reduced preparation time of the cleaning surface. In many situations Soda can be used in situ, without masking up or covering of adjacent surfaces. For example an aluminium or wooden window frame can be cleaned “as is”, without masking or removing the glass; unlike sand, Soda will not etch or mark glass or rubber. No pre-cleaning of the surface is required
Dry cleaning method, essentially SodaBlasting was developed as a “dry” process, it can however be used in conjunction with either high or low pressure water cleaning or with a water shroud to reduce dust. Dry cleaning methods can be used successfully on food processing lines and plastics factories where water cleaning is not an option. Dry, Soda can even be used to strip away years of grime and varnish from wooden floors and tables. Soda is an extremely effective method of cleaning up oil and grease marks from concrete. As a wet cleaning method SodaBlasting is highly successful in removing graffiti from walls, old surface paint, surface stains and even bubblegum from floors.
Non-Toxic blast media. Soda, unlike sandblasting is non-toxic and poses no immediate or long-term health risks to the operators or clients on a cleaning site. Soda is water soluble and is simply metabolised by the body. Blasted soda dust may however, contain traces of the paint (or other surfactant) which may contain toxins, for this reason protective breathing apparatus is always worn as a precaution. Bicarbonate of Soda has been in household use for about 160 years and its uses and chemical properties are widely documented. Soda is in fact used in many house hold products (baking soda, toothpaste and scouring agents amongst others). Can reduce the use of solvents and hazardous chemical cleaning applications; SodaBlasting is environmentally friendly.
100% water soluble, this means the post-cleaning site cleanup is swift, the debris can be swept and vacuumed up, water can then be added and the solid debris (e.g. old paint chips) can then be strained and disposed of. The water containing the Soda can simply be flushed or poured into the storm water system as it has no negative effects on effluent reticulation systems.
Cleaning & De-Coating in One Step, in the food and automotive industry SodaBlasting not only cleans, but it also removes grease, oil, fatty deposits and food deposits in one single operation.
Removes Odours, baking soda has been used for years to removes unpleasant odours; blasting with soda can remove lingering smells such as decay, mould and even smoke (common with fire damage)
Able to clean in difficult to reach areas; as Soda is applied by compressed air, it can be effectively applied to a distances of up to 50 - 60cm from the application nozzle; allowing it to be used behind ventilation or air-conditioning ducts
The medium is not flammable removing the risk of accidental fires or even flash explosions. The medium does not produce sparks as is the case with certain other media.
Less down-time, in some instances SodaBlasting can be used while machinery or equipment is still in use; rotating equipment can be cleaned in situ without damaging rollers or bearings
No need to re-profile the substrate. Certain other cleaning methods result not only in the coating being removed, but also the smoothing of the substrate profile (as is the case with glass beads), here the coating is removed, but the profile of the metal is “polished” flat. Soda removes the coating and restores the original metal profile (if one existed prior to the coating).
With regards to equipment cleaning, there is no size restriction; the smallest piece of equipment can be cleaned in a blast cabinet as effectively as the largest turbine blade or cooling coil in an outdoor situation.
In some industries, composite parts can be cleaned in a single operation with no adjustment to the output pressure or fear of damaging a softer component
Temporary rust-proofing of metal. The high pH of the Soda results in a temporary cessation of oxidisation (rusting) of ferrous based metals; the effect is temporary (about 2 weeks) before oxidisation will resume. This does however cause bonding problems if you wish to apply a primer and paint finish to the metal; in this case the metal has to be washed down with a mild acid and water to remove the alkaline coating on the metal.
Less cleanup, as Soda breaks down on impact and as it is water soluble this results in less “on-site” waste by volume, up to 20% that of using sand as a blast media!
