Steel Abrasives Tag

On this occasion we have to talk about energy since the process of shot blasting a piece is done by transmitting kinetic energy to an area.

The formula tells us that the kinetic energy is equal to one half of the mass times the speed squared, that is to say that the variables here would be the mass, which is the size of the particle and the quantity that is thrown plus the speed, since either the particles are blown by means of a wheel or by air pressure through nozzles in an airblast system.

The particles are accelerated through these media to transmit that energy and do the cleaning work; Another very important variable is the hardness of the particle, and in the case of steel abrasive, it is defined by the amount of carbon it contains.

Therefore, there are two types of abrasives on the market: low and high carbon steel. But how do we know which one suits us best?

Manufacturers of low carbon shot may claim that their product is better than high carbon shot

What material is more efficient to clean or polish the surface of metal parts?

Here we tell you some details and differences about the abrasives known as "Steel Abrasive" and "Silica Sand"!

The surface treatment of metal parts is essential for future conditioning or work in the workshop. And the abrasives mentioned above can help you give them that perfect finish you need, but which of the two is better to optimize efficiency, speed, quality and cost?

To make the best decision, you must take into account elements such as size, shape, hardness and fragility.

For example, starting with the "Silica Sand", which due to its extreme fragility and thanks to the fact that it is projected by high production equipment, can only be used once since up to 80% of the material turns into dust.

To understand the how well, we need to understand well what is sand blast or sandblasting? The definition of this word is understood as “sand under pressure”; however, numerous abrasives in addition to sand can be used in this operation to clean, polish or remove materials and residues from different surfaces.

In areas of abrasives, we have 2 types commonly used:

ARTIFICIAL ABRASIVES

• Aluminum oxide
• Steel shot
• Silicium carbide
• Sodium bicarbonate
• Cut wire
• Garnet
• Copper slag
• Glass pearl
• Plastic abrasive

NATURAL ABASIVES

• Silica sand
• Diamonds
• Quartz
• Corundum

To sandblast, we use compressed air which propels the abrasives at
