Clean and degrease surface has as objective to remove the different contaminants that may exist on the surface of a material, contaminants such as grease, wax, oil, dust or other, due to transportation, handling or warehouse of the materials.
The process of cleaning and degreasing of the material is the first step towards the application of paint, lack of cleaning and degreasing directly produce a lack of adhesion of paint applied, losing all the time and effort invested in the application of paint.
The process of cleaning and de degreasing involved in 2 operations:
Clean - Refers to the process of removing solid contaminants such as dust, mud, rust, etc ... Generally it realize by mechanical ways such as brushes, sanding, blasting, etc ...
Degrease - Refers to the process of removing chemical contaminants located on the surface of the material such as grease, oils, lubricants, polar compounds, etc ... degreasing surfaces is usually done by cleaning agents such as organic solvents or aqueous cleaners.
Depending on surface condition will be necessary to do a clean and / or degrease, if the material does not contain a high concentration of solid contaminants, products used in degreasing process are able to eliminate this type of contaminants.
Currently there are different methods or techniques can be used for carrying out the process of cleaning and degreasing, the optimum choice of materials and process is defined by:
The concentration or amount and composition of contaminants that contains the surface.
Degree of cleanliness required.
Type of substrate material (aluminium, steel, PVC, glass ...)
Characteristics of the workpiece, shape, size, geometry...
Environmental and health safety requirements.
Among the different methods of cleaning and degreasing we find:
Cleaning by mechanical treatment
Manual cleaning and degreasing
Immersion cleaning and degreasing
Vapour cleaning and degreasing
Cleaning and degreasing by spray
Cleaning and degreasing by ultrasonic
Cleaning and degreasing by laser
Cleaning and degreasing by Plasma
Cleaning and degreasing by Biological action
