Blasting is an umbrella term referring to processes that involve propelling abrasives against surfaces to clean or shape them. The degree of results is dependent on the force of propulsion. The machine used is called a sandblasting device. When in need for service providers of services of sandblasting Los Angeles should be prioritized.
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.
The idea of wet blasting was pioneered by Ashworth Norman. The many advantages that wet blasting offered compared to sand blasting is what attracted Norman to it. Many countries had also made sand blasting illegal because it caused health problems. As the first advantage, a wide range of media densities can be used in the process. For example, plastic and metal can be used. Also, the machine can blast and still wash the surface at the same time if soap is added in the water. Water also wets silicacious materials rendering them 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, this process can be achieved by many machines. The machines vary in various aspects such as efficiency, cost, complexity, and size. There are large machine for use in commercial processes and small ones for private use at home.
