Sand blasting is also known as abrasive blasting. Actually, it is the process of forcibly propelling a stream of abrasive material against a surface. The sand blasting operation is done under high pressure to smooth a rough surface and roughen a smooth/Shape surface to remove its contaminants. There are several variants of sand blasting processes like bead blasting, Soda blasting, and shot blasting machine.
Before sand blasting, it is mandatory to know about its materials and the pros and cons. If your job profile is related to sand blasting or you owned a company that is involved in the same process, you need to stay with us. In this article, we will discuss the sand blasting machine's materials and their pros and cons. But before it, let me also clarify some of the details of its operation.
There are several types of abrasive blasting including, silicon dioxide, soda, steel shots, bristle, glass bead, and many more. All several abrasive sand blasting processes normally use a special type of grit to achieve the desired results, so determining the best medium for the job is crucial to success.
Below is a more detailed list of some of the various types of sand blasting abrasive mediums that can be used:
Silicon Dioxide relates to ordinary sand, which is also known as silica or quartz sand. Silica Sand blasting was a generally utilized process of removing impurities from surfaces; this is because sand particles are almost the same size and the edges of the particles are sharp, hence creating this type of grit efficient in abrasive blasting.
For a matte and satin finish, glass bead sand blasting can be utilized. This medium has very fine substances (materials) that polish the surface of the object being sand blasted. This type of abrasive blasting is often utilized in cabinets.
In this method, steel grit is utilized as an abrasive in the removal of rust and paint from steel metals. The use of steel leaves a smooth finish.
In this type of abrasive blasting, no separate medium is used. Alternatively, steel wire bristles are rotated on a surface. This rotating action helps in the removal of impurities, hence leaving the surface smooth. This technique is often utilized to clean metal surfaces with some form of corrosion.
Soda sandblasting relates to the usage of baking soda or bicarbonate of soda in the blasting process. Soda is utilized as an abrasive to remove rust from metals without causing depression or damaging the metal beneath the rough surface. Soda is also a famous grit to use on delicate materials that may be destroyed by tougher abrasives
