All processes in which materials are used to clean or shape surfaces by propelling them are grouped under the umbrella term blasting. How fast the particles are propelled determine what results are achieved and to what extent. A sandblasting machine is the device used for this process. When one needs professionals in sandblasting Los Angeles has to be the place to prioritize.
The process was first patented in 1870, but since that time, it has evolved and become a common practice. In fact, several variants of the process have been developed to suit various applications. Some major variants include sodablasting, shot, wet, bead, dry ice, hydro, automated, and wheel blasting among many others. This article will discuss the major variants of the process that are in common use today.
Wet blasting was pioneered by someone called Norman Ashworth because of the advantages it offered over its sand counterpart. Sand blasting had been banned by many countries at that time because of the health issues associated with it. Wet blasting allows the use of media of a wide range of densities including plastic and steel. It also removes grease while blasting at the same time. Water helps to wet silicacious materials making their use safe.
The operator in wet blasting is also safe even from dangerous materials like radioactive substances and asbestos. Common formats in which the process can be done include walk-in booths, automated production machinery, hand cabinets, and total loss portable blasting units. The speeds under which this process can be done have increased making wet blasting compete dry blasting in this aspect.
Another variant is the wheel blasting. In this variant, the abrasive is propelled against a surface by centrifugal force generated by a wheel. The absence of air or liquid has made this process to be categorized as airless blasting operation. The machine used for this process is called a wheel machine and some of the abrasives that can be used include cut-wire, steel shot, and grit. Different machines have different number of wheels which can be set to different levels of power. Efficiency and speed at which work needs to be done can be set on the machine.
Micro-abrasive blasting also goes by the name pencil blasting. In this variant, very small particles are used. The particles range in size from 10 to 150 micrometers. Surfaces mostly blasted are also very small, normally in the range of a few centimeters maximum. Very high pressure is used to deliver the abrasive accurately on the surface in form of a stream. The process is done very delicately.
Dry ice blasting employs a combination of air and frozen carbon dioxide. The combination is propelled at extremely high speeds to dislodge surface contaminants. Bonds between the contaminants and the surface are dislodged by the freezing effect of dry ice. The resultant surface is clean without any kind of residue because of sublimation.
Generally, there are several machines that are used to achieve this process. They vary in size, complexity, efficiency, and cost among other factors. Large machines are meant for doing the activity on a commercial scale while the small ones are for private use in most cases.
