Sandblasting is a process of treating surfaces and is widely used in different industries for many different purposes. It is the process through which an abrasive is accelerated into a

surface via the use of a blasting nozzle using compressed air. Common abrasives used include corn nob, plastic, copper slag, glass bead and steel shots. During sandblasting, selecting the media to be used is so crucial. This is because the different types of abrasive media vary in shape, density, availability and hardness. Also the particle size is worth considering. In most cases, before sand blasting is carried out, it is usually important to lock in the size and type of media to be used.

A sandblasting set up consists of three parts: a blaster nozzle, an air compressor and the abrasive itself. For small object cleaning and etching, a workstation that will hold the glass will also be required. A sort of collector might also be required so as to collect the excess dust. Residential sandblasting is therefore used for different applications. The common use is to clean a surface by removing whatever might be clinging to it while the other application is to carve words or designs into any given materials. The process of sandblasting will ultimately depend on how the end component will be used. Initially, residential sandblasting was considered a low technology process. However, the application of sandblasting in preparing surfaces for coating has improved this as sandblasting plays a vital role in giving surfaces the required luster and texture. The following are some benefits of residential sandblasting.

De-coating and cleaning in one step

Abrasive blasting is usually a dirty process. This is because it at times loads and embeds surfaces with contaminants like abrasive particles, tar, oil and grease during the process of coat removal. The recycled abrasives reload the increased amounts of contaminants. Suing specific types of abrasives like sodium bicarbonate ensures that surfaces and de-coated and cleaned without spoiling the surface. The sand blasting process often results in cleaner surfaces.

Cutting action

Depending with the abrasive used for sandblasting, the process often results in unique cutting action. The use of abrasives such as sodium bicarbonate and others, with a hardness not exceeding 2.4 on the Moh scale, usually results in nicely cut surfaces. The crystals produce a very nice surface without affecting the substrate. For instance, sandblasting can allow the easy removal of thick coatings from glass without engaging any etching procedures.

Eliminates odors

Residential sandblasting removes bad smells. Some surfaces tend to produce strange smells due to different reasons, such as rusting, rotting or decaying. The use of different abrasives in sand blasting ensures that these smells are eliminated. For instance, the use of glass beads as sandblasting abrasives will lead to low levels of oxidation. This results in reduced rusting or decaying, and in the process the smell is eliminated. The blasting removes the contaminates and other unfriendly smells. The use of de-greasing abrasives often eliminates the need for solvents when carrying out cleaning processes. Most sandblasting abrasives do not emulsify or dissolve in oils or grease, but rather coats them.

Crack detection

Depending with the nature of material used, the application of sandblasting is considered safe. This is because it does not result in the production of sparks. The production of sparks might cause explosions in areas that are not explosion proof. Sandblasting therefore plays a great role in cleaning surfaces that would otherwise be considered as being at risk of catching fire in the event that sparks are produced, such as grain elevators, chemical plants and refineries. Sandblasting can be used as a crack detection mechanism when sandblasting metal surfaces. Depending with the abrasive used, crack detection and repair is made easy. This makes the application of this process wide as it can be applied in different fields.

Rust inhibitor

Sandblasting inhibits the buildup of rust. Some abrasives are air proof and will not allow air to penetrate to the surface hence causing rusting. Rusting occurs where acidic conditions and free moisture exist. As is the norm, carbon dioxide found in the atmosphere usually combines with moisture hence resulting in most metal surfaces. The carbonic acid formed often releases free metal ions that cause rusting. The use of different sandblasting abrasives buffers the acid by preventing the release of the ions and hence preventing rusting.
