Economic and Environmental Benefits of Plasma Cleaning

Many industries prefer using the plasma technology to clean surfaces before applying any other treatments. For a start, this technology allows industries to get very clean surfaces regardless of the material in question. The technology can always be customized to suit the material at hand. Sensitive materials like polymers as well as other common options like metals can undergo plasma cleaning.

The technology can be used to ensure that all areas of the surface are uniformly cleaned. There are many more economic and environmental advantages of using the plasma cleaner. Some of these are going to be mentioned below.

In order to understand why many people prefer this cleaning system, you need to understand the plasma definition. The physical process is easy to understand. If the sample plane is conductive, positive ions will be directed to this plane, which acts as a cathode, using an electric field. These ions hit the surface with great speed removing any atoms and molecule from this surface.

You will be able to understand the plasma definition more if you also look at the chemical process that is involved in cleaning. In the chemical process, oxygen atoms, and their ions are allowed to react with hydrocarbons. When this reaction takes place, carbon dioxide and water is formed. The hydrocarbons are then converted into harmless gases and any remaining products removed by the activated carbon. Once the process is complete, the entire surface is cleaned without the need for further filtering in case there are any products left behind due to incomplete combustion.

Another advantage of using plasma technology is that cleaning is done evenly and thoroughly throughout the surface. Cleaning is done uniformly and consistently throughout the surface using positive ions and electrons which are accelerated in opposite directions. This cleaning system is best in planar samples because plasma action is evenly distributed along the plane to be cleaned.

This technology can be used to clean a wide range of materials including metals, rubbers, ceramics, glass and polymers. The system plasma must be adapted to the task. The gas mixture must be prepared depending on the surface to be cleaned. For instance, reductive plasma will be used to eliminate inorganic deposits on surfaces. These deposits could be metal oxides which must be removed in order for the surface to receive additional treatment like painting and hard coating. On the other hand, oxidative plasma systems have been used to get rid of organic impurities, like grease, on a surface.

To conclude, there are many advantages of using plasma applications in cleaning surfaces today. To start with, the process of cleaning is easy to control, stable and can be used in different materials. On the other hand, there are many economical benefits of using this method of cleaning. The advantages include the fact that there is no extra cost of disposal. Also no drying of the surface is needed and the plasma gases which are used in the cleaning process are very minimal. The environmental benefits of using plasma technology cannot be overlooked. The cleaning system is safe for the environment and provides workplace safety.
