What is sandblasting? Know it to use it properly

Posted by qualitysparecentre in Technology on November 14th, 2018

Sandblasting is the process of cleaning, smoothing and shaping the surface by blasting solid particles like sand, baking soda, nut shells etc, at high speed. Sandblasting is also known as abrasive blasting. The effect is similar to sandpaper, but Sandblasting provides a smoother and more uniform surface. This procedure is used to remove paints before applying a new paint or coating. It can also be used to remove parts of paint to create a new decorative pattern.

This process is carried out with various items such as sand, grit or shot. Although this blasting is done to remove paint, rust is often used to reflect a particular shape. Sandblasting is undoubtedly a popular technical term, and many people have heard of it. People are so interested in sandblasting products that they arrange and present sandblasting products as freebies. The sandblast template is also considered an innovative art form. Sandblasting has become viral today, which is nothing more than the process of pressurizing tiny pieces of material at very high speed to clean a surface.

Materials used in Sandblasting:

Although it is known as abrasive blasting, there are several other materials that play a role in sandblasting. Among all the ingredients there are steel grit, walnut shells, copper slag, powdered abrasives, small pieces of coconut shells and also steel grit. In recent years, all of these materials are inconsistent utilization, and all of these ingredients are sandblasted for referenced reasons, and their advantages are also multiple in number. However, there is a material that cannot be sandblasted, that one is Diamond. This is because diamond is harder. Sand is almost not blasted today, as it can cause lung cancer (silicosis). Prolonged inhalation of dust causes this lung failure.

Sandblasting procedures:

The Sandblasting process refers to the act of propelling abrasive from a sanding nozzle, directing it to a targeted surface such as concrete, steel, brick, and rock. It takes an experienced sandblaster to control the speed of the abrasive.

Sandblasting can improve the appearance of surfaces by eliminating stains, compound residues, corrosion and tool marks. Some blast media can mix surface variations to give a uniform appearance. The sandblasting process can be divided into six areas: sandblaster, air compressor, blast machine, nozzle and abrasive.

The abrasive is propelled by the high speed sand blasting nozzle, sometimes dry, sometimes wet, depending on the targeted surface. The abrasive uses the force of the compressed air to achieve the desired result. The selection of the right abrasive for the job is crucial. Choosing the wrong abrasive for the targeted surface can result in expensive rework or, in the case of concrete, re-casting. Keeping that in mind, choosing an experienced sandblasting company will save you time and money.
