Why Soda Blast

Soda blasting has several positive qualities. Traditional sand blasting Is To aggressive for the likes of Car bodies and thin metal panels , which cause heat to build up during the blast cleaning process. With thinner steel, and most definitely aluminium, this can cause panel distortion and warping. The new replacements Soda blasting does not have this risk.

Soda blasting cannot heat warp panels the same as Sand Blasting

If you need a reliable system to strip coatings from fibreglass or carbon fibre, soda blasting is the most effective option on the market. Unlike other blast cleaning media paint stripping methods, soda stops when it reaches the substrate. This means that when the coatings are stripped away,

won’t damage the fibreglass, steel, aluminium etc

Other techniques can cause pitting to the surface material if the media is propelled onto the same area for too long, whereas soda will not.

blasting is the safest and most environmentally friendly alternative to sand blasting and grit blasting.

WHAT IS SODA BLASTING?

Soda blasting is probably the safest and least abrasive way to strip paint and contaminants from surfaces. As soda crystals make contact with a surface, they are fractured, causing them to break apart. This blast cleaning method peels away coatings using energy created by the tiny soda crystals breaking apart. The crystals are propelled onto a surface using compressed air, through a machine that is controlled by the operator – usually Dave or James in our case! Soda blasting is considered revolutionary because it is unlike other blasting methods that use the roughness of a chosen media to scratch away surface coatings.

 

Media

In the early 1900's, it was assumed that sharp-edged grains provided the best performance,

But this was later demonstrated not to be correct.

Mineral: Silica sand can be used as a type of mineral abrasive.

It tends to break up quickly, creating large quantities of dust, exposing the operator to the potential development of silicosis, a debilitating lung disease. To counter this hazard, silica sand for blasting is often coated with resins to control the dust. Using silica as an abrasive is not allowed in GermanyUnited KingdomSweden, or Belgium for this reason.

Silica is a common abrasive in countries where it is not banned.

Another common mineral abrasive is garnet. Garnet is more expensive than silica sand, but if used correctly, will offer equivalent production rates while producing less dust and no safety hazards from ingesting the dust. Magnesium sulphate, or kieserite, is often used as an alternative to baking soda.

Bead blasting

Bead blasting is the process of removing surface deposits by applying fine glass beads at a high pressure without damaging the surface. It is used to clean calcium deposits from pool tiles or any other surfaces, remove embedded fungus, and brighten grout color. It is also used in auto body work to remove paint. In removing paint for auto body work, bead blasting is preferred over sand blasting, as sand blasting tends to invite rust formation under re-painted surfaces. It's additionally used in cleaning mineral specimens, most of which have a Mohs hardness of 7 or less and would thus be damaged by sand.

Micro-abrasive blasting

Main article: Abrasive jet machining

Micro-abrasive blasting is dry abrasive blasting process that uses small nozzles (typically 0.25 mm to 1.5 mm diameter) to deliver a fine stream of abrasive accurately to a small part or a small area on a larger part. Generally the area to be blasted is from about 1 mm2 to only a few cm2 at most. Also known as pencil blasting, the fine jet of abrasive is accurate enough to write directly on glass and delicate enough to cut a pattern in an eggshell. The abrasive media particle sizes range from 10 micrometres up to about 150 micrometres. Higher pressures are often required.

The most common micro-abrasive blasting systems are commercial bench-mounted units consisting of a power supply and mixer, exhaust hood, nozzle, and gas supply. The nozzle can be hand-held or fixture mounted for automatic operation. Either the nozzle or part can be moved in automatic operation.

Automated blasting

Automated blasting is simply the automation of the abrasive blasting process. Automated blasting is frequently just a step in a larger automated procedure, usually involving other surface treatments such as preparation and coating applications. Care is often needed to isolate the blasting chamber from mechanical components that may be subject to dust fouling.
