Once the surfaces have been abraded, they need to be degreased to remove the debris from abrasion.ĭry abrasion is a mechanical technique where the operator hand sands or wire brushes the substrate with a medium abrasive material. The surfaces need to be degreased and cleaned before as well as after abrasion to remove any pre-existing contaminants on the surface. Some of the most effective mechanical methods used include sand blasting, wire brushing and abrasion with sandpaper or emery cloth. Mechanical abrasion of smooth surfaces is employed in order to remove heavy loose surface deposits such as dirt, oxide layers or any other contaminants that might be deposited on the surface. Cleaning and drying the substrate post the degreasing.Immerse the substrates in a fresh bath of solvent for the wash and follow by an immersion in the second tank for a rinse.Vapor degrease/clean/rinse the parts with the appropriate solvents.The most common methods used, typically include the three main steps: However, kindly make sure that all the environmental, health and safety regulations are met prior to selecting a solvent. Surfaces can be degreased using volatile solvents such as toluene, acetone, methyl ethyl ketone, methyl alcohol, isopropyl alcohol and trichloroethylene. Ph.Degreasing is carried out in order to remove any loosely held dirt or other contaminants from the surface. Over 10 years of experience as General Manager of R&D and business development.
