Abrasive Blasting

Soda blasting is a mild abrasive blasting method using sodium bicarbonate (baking soda) particles. It is a non-destructive method used for cleaning or preparation of surface for the next technological steps. The media of soda blasting is non-toxic, environmentally friendly, the material is bio-degradable, and it doesn’t pose any health hazards.

Walnut shell blasting is an abrasive method using crushed walnut shells for cleaning or preparation of the surface for the next technological steps.

Before the introduction of walnut shell blasting, coatings were normally stripped down to bare metal and required a replacement of the undercoat, vinyl coat, and topcoat. This coating removal blasting technology also enables selective coating removal and saves significant time and money. 

At present, walnut shell blasting is being used safely and effectively across a range of industries and applications.

The media is also durable, re-usable and biodegradable and reduces the cycle time of finishing operations; it preserves microfinishes and replaces sand to prevent silicosis. Selective coatings removal is also possible with walnut shell sandblasting.

Specifically intended for use in dry air blasting applications, walnut shells are a lightweight, angular media that will effectively remove topcoats while leaving undercoating intact.

Walnut shell does not contain heavy metals or free silica. Walnut shell is resistant to rupture and deformation, allowing for it to be recycled up to four times. Specialty petrochemical or offshore applications where a minimal sparking, non-ferrous abrasive is required.

Sponge blasting is a unique abrasive blasting method. The sponge blasting process provides suppression of up to 99% of dust and abrasive ricochet in comparison to other blasting methods.

Superior Results — Saving Time and Money.

Achieve sustainable, safe, environmentally responsible and superior surface preparation. Sponge-Jet’s unique technology allows contractors, managers and engineers to switch from costly, outdated processes and improve coating performance.

Sponge Media is light and easily removed from aping after blasting unlike heavy abrasives which can be a challenge to remove from long piping.

Sponge removes and captures grease, oil, and other contaminates – unlike dry ice or ordinary abrasives which may dislodge the contaminate from the surface but without capturing – the contaminate is often redeposited on the pipe surface.

Reduced Dust and no ricochet allows the cameras on the JettyRobot to perform longer than they could with ordinary abrasive.

Abrasive blasting, more commonly known as sand blasting, is the operation of forcibly propelling a stream of abrasive material against a surface under high pressure to smooth a rough surface, roughen a smooth surface, shape a surface or remove surface contaminants.

A pressurized fluid, typically compressed air is used to propel the blasting material (often called the media).

The most abrasive are shot blasting (with metal shot) and sandblasting (with sand).

Sandblasting equipment typically consists of a chamber in which sand and air are mixed. The mixture travels through a nozzle to direct the particles toward the surface or work piece. Nozzles come in a variety of shapes, sizes, and materials. Boron carbide is a popular material for nozzles because it resists abrasive wear well.

You can find a nice article on Sand blasting on Wikipedia with a detailed explanation of various sand blasting methods.

Grit blasting is a process by which abrasive particles are made to impinge on a component, in order to clean or modify its surface properties.

  Not applicable

It is often used to prepare surfaces before welding (removal of scale, rust or paint), and, afterwards, to improve the adhesion of coatings.

The impact of the grit on the metal surface puts the surface layer into compression, and this effect can be beneficial, for example, in reducing stress corrosion cracking in aluminium alloys.

Shot blasting is a method used to clean, strengthen (peen) or polish metal. Shot blasting is used in almost every industry that uses metal, including aerospace, automotive, construction, foundry, shipbuilding, rail, and many others. The technology used is air blasting.

Shot Blasting is a surface finishing technique that involves rapidly impacting the surface of an object with a controlled stream of abrasive shot material. 

Shot Blasting is also used for removing burrs, scale and rust that may interfere with the part’s integrity, appearance or definition. Shot blasting can also prepare the surface of a part for coating by removing surface contaminants and provide a surface profile for increased coating adhesion.

Abrasive blasting, more commonly known as shot blasting, is the operation of forcibly propelling a stream of abrasive material against a surface under high pressure to smooth a rough surface, roughen a smooth surface, shape a surface or remove surface contaminants. A pressurized fluid, typically compressed air is used to propel the blasting material (often called the media). 

There are several variants of the process, using various media; some are highly abrasive, whereas others are milder. The most abrasive are shot blasting (with metal shot) and sandblasting (with sand). Moderately abrasive variants include glass bead blasting (with glass beads) and media blasting with ground-up plastic stock or walnut shells and corncobs. Some of these substances can cause anaphylactic shock to both operators and passers-by. A mild version is soda blasting (with baking soda). In addition, there are alternatives that are barely abrasive or nonabrasive, such as ice blasting and dry-ice blasting.
