Shot blasting vs sand blasting

Shot blasting and sandblasting are two popular methods of abrasive blast cleaning, which involves shooting powerful streams of abrasive materials at a surface to break down the superficial layer and reveal a clean layer underneath. While these two techniques may sound similar, there are some key differences between them.

Sandblasting

Sandblasting is the process of propelling abrasive media using compressed air to clean a surface. This method uses compressed air as a power source to direct a high-pressure stream of abrasive media, such as sand, towards the surface. Sandblasting is ideal for cleaning soft and sensitive materials, as it is a less forceful, less invasive, and more flexible procedure. It is also typically cheaper than shot blasting.

Sandblasting can be used on a variety of surfaces, including auto parts, rusty chains, and old filing cabinets, to remove dirt, grease, oil, coatings, rust, scale, and other contaminants. The texture of the surface after sandblasting depends on the size and type of abrasive material used.

One of the main drawbacks of sandblasting is the health risks associated with it. The fine dust residue created during the process can be inhaled, leading to potential respiratory issues. As a result, sandblasting with silica sand is banned in some places.

Shot Blasting

Shot blasting, on the other hand, uses centrifugal or mechanical force to shoot a rapid stream of abrasive material at a surface. This force is typically achieved through a rotating turbine wheel. The abrasives used in shot blasting can vary depending on the surface and the nature of the project, but steel is the most common. Shot blasting is ideal for cleaning steel and other ferrous metal surfaces.

Shot blasting is a more aggressive and forceful technique than sandblasting, making it more effective against tougher materials. It is also environmentally friendly, generating minimal byproducts and eliminating the use of non-eco-friendly chemicals. Shot blasting also helps remove rust and corrosion from surfaces.

Shot blasting results in a slightly different finish compared to sandblasting. While sandblasting creates a fully smooth profile, shot blasting creates a slightly textured surface. This added texture allows for better adhesion of secondary coatings, increasing their durability.

There is no definitive answer to which method is better, as it depends on the specific requirements and expectations of the project. Both sandblasting and shot blasting have their advantages and are suitable for different types of surfaces and finishes.

Sandblasting is generally quicker, more economical, and less likely to cause damage to sensitive surfaces. It is a preferred method for cleaning delicate electronic parts or connectors that have corroded.

On the other hand, shot blasting is more effective for denser and more complex surfaces that require a strong application force and denser media material. It is often used for large-scale operations and on surfaces like automobile frames, steel containers, and engine components.

In summary, the choice between sandblasting and shot blasting depends on the specific needs of the project, the type of surface being treated, and the desired finish.

Eco-friendly sandblasting

Sandblasting is a process that involves the forceful propelling of an abrasive medium against a surface. While sandblasting is an effective way to strip, prepare, clean, or remove surfaces, sand is no longer used due to the dangers of silicosis. However, several eco-friendly alternatives are now available that are safe, sustainable, and climate-neutral.

Eco-Friendly Alternatives to Sand

One such alternative is vacuum blasting, a patented technology that uses a vacuum to suck in blasting media such as jet glass, asilit, or granulate. This process achieves effective cleaning and optimal dust binding without the need for high pressure, water, or chemicals. The dirt and paint are quickly removed from the surface, and the blasting media can be reused multiple times.

For brick, natural stone, and concrete, jet glass and asilite are the most suitable options. Meanwhile, for more delicate surfaces like polished granite or glazed tiles, a special granulate made from nutshells is used.

Benefits of Eco-Friendly Sandblasting

Additionally, eco-friendly sandblasting is highly flexible as it can be used on-site without requiring an external water source, saving time and resources while contributing to environmental conservation. This technology is also climate-neutral and does not leave any harmful residues, making it a valuable tool for environmental protection.

Sandblasting applications

Sandblasting is a versatile process that can be used to clean, etch, and prepare surfaces before they are painted or coated with another material. It is also used to remove paint or create decorative effects on buildings, signage, and boats.

Sandblasting is often used to remove old paint and rust from surfaces prior to painting. It can also be used to roughen smooth surfaces, like concrete, so that paint or other coatings adhere better. This process is called "rough-blasting" and is usually done on the lower part of an object, where it is less visible. Sandblasting is also frequently used to remove graffiti, as it can achieve intricate designs and fine details through the use of templates.

Sandblasting is an effective method for removing rust from metal and can be used to create a key for paint or other coatings applied to concrete or wood. It can also be used for fire damage clean-up and to etch concrete surfaces for decorative effects. Sandblasting is often used to clean and prepare surfaces for painting, and can be used to remove dirt, debris, scratches, and casting marks. It can also be used to smoothen or roughen surfaces, and to add texture or design through etching.

Sandblasting is also suitable for cleaning sensitive electronic components and corroded connectors. It is considered a gentler abrasion technique compared to shot blasting, but its intensity can be varied by adjusting the type of sandblasting equipment, the pressure of the compressed air, and the type of abrasive media used.

Sandblasting is a conventional method of preparing metal substrates and material surfaces before applying treatments, coatings, or other finishes. It is an economical process that can be used for stripping paint, deburring, cleaning, bright finishing, scale removal, shot peening, and adding decorative etching or fine finishing.

Sandblasting furniture

Sandblasting is a popular method for restoring wooden furniture. It is a process that involves propelling small particles such as sand, walnut shells, or even crushed glass against a surface to remove paint, rust, or other surface coverings. This technique is often used to give furniture a rustic or distressed look, or to create a driftwood effect.

When sandblasting wooden furniture, it is important to choose the right type of abrasive substance, as they have different effects on the surface. For example, walnut shells or corn cobs are softer and less likely to damage the wood, while sand or crushed glass will create a more pronounced effect. The pressure and distance of the sandblaster from the surface will also affect the results. It is recommended to start with a test piece of wood to get a feel for the process and adjust the settings accordingly.

Safety is a key consideration when sandblasting. It is important to wear protective clothing, including goggles, gloves, and a long-sleeved shirt, work boots, and pants. The work area should be well-ventilated, and tarps should be placed around to catch the abrasive material. Sandblasting can create a lot of dust and mess, so it is often done in a sandblasting booth or outdoors.

Sandblasting metal

Sandblasting is a process that uses an abrasive medium and pressurised air to clean a surface, leaving it ready for painting or other finishing techniques. It is an effective way to remove rust or paint from metal, and can be used on a range of materials including cast iron, wrought iron, and aluminium. Sandblasting is often used to restore the natural beauty and characteristics of items such as fireplaces, log burners, stoves, gates, stairways, and frameworks.

There are several types of abrasive media that can be used for sandblasting metal, each with its own unique properties and benefits. Silica sand, or ordinary sand, was once the primary method for sandblasting as it can effectively remove surface impurities without causing damage. However, due to the risk of developing silicosis, a lung disease caused by inhaling silica dust, other abrasives are now typically used.

One alternative is soda sandblasting, which is ideal for softer metals as it does not react chemically and is less abrasive. For both blasting and scraping, steel grit can be used. It is effective at removing corrosion and rust from hard metal surfaces and is commonly used in automotive, aeronautics, and heavy machinery. Steel grit also leaves a smooth finish and is recyclable.

Glass bead sandblasting is another option, which is perfect for paint preparation and provides a unique matte or satin finish. It is suitable for a range of metals, especially softer ones like aluminium. The beads are silica-free and environmentally safe. For harsh surfaces with difficult corrosions or burrs, bristle blasting can be used. Steel bristles are arranged in a brush-like fashion and rotated on the metal surface to remove impurities and provide a smooth finish.

When sandblasting metal, it is important to select the appropriate equipment and take necessary safety precautions. This includes wearing protective gear such as eye and ear protection, gloves, and a respirator to prevent inhalation of dust or debris. Additionally, it is crucial to maintain a consistent pressure when using a sandblaster to avoid damaging the material.
