Abrasive blasting which is also generally referred to as sandblasting Machine is a process in which a medium is used to smoothen out or polish a rough surface. Rust and corrosion are general problems and normally sandblasting is a fast and efficient solution to rebuilding machinery, vessels, and metal parts back to their former condition and looking their best. Abrasive blasting can also be used to fix surfaces that may need repainting.
Abrasive blasting is a method where an abrasive material, known as a medium, is chosen to blast into a surface to restore its smoothness or remove contaminants. The amount of pressure will determine how long the process will take and the quality of results.
The term “sandblasting” was used basically, as when the process started in the past, sand was the only medium remaining used. These days other types of mediums are now being utilized, depending on the surface, the type of metal and the job being undertaken.
different types of sandblasting abrasive mediums that can be used:
Silicon Dioxide refers to common sand, which is also known as silica or quartz. Silica Sandblasting was an ordinarily used process that is used for removing impurities from surfaces; because the sand particles are almost the same size and the edges of the particles are sharp, hence making this type of sand useful in abrasive blasting.
For a matte and silky finish glass bead sandblasting can be used. This medium has very fine materials that polish the surface of the object doing sandblasted. This type of abrasive blasting is usually used on cabinets.
In this process, steel grit is generally used as an abrasive in the removal of rust and paint from steel metals. The use of steel leaves a smooth finish. Steel grit is can usually be preferred due to its fast cutting nature.
In this type of abrasive blasting, it is no separate medium is used. Instead, steel wire bristles are turned on a surface. This rotating activity aids in the removal of impurities, hence leaving the surface smooth. This method is usually used to clean metal surfaces with some form of corrosion.
Soda sandblasting relates to the use of baking soda or bicarbonate of soda in the blasting process. Soda is used as an abrasive to remove rust from metals without causing depression or damaging the metal below the rough surface. Soda is also great sand to use on fine materials that may be destroyed by tougher abrasives.
