Hello Dears ;
Why we use the Ethanol Alcohol for cleaning the surface of polymeric materials.?
Ethanol is a comparatively cheap solvent and can dissolve any undesirable organic substances accumulated on the surfaces to clean it.
Besides cheapness, ethanol is usually provided as 92% or 95% which means a water content of 8% or 5%. As such, the mixture ethanol/water will display adequate solvating power to cleaning the surfaces of polymers. We better not use absolute ethanol (~100%) for cleaning polymers.
Belouadah Abdelhakim : please check "solvents and non-solvents" for any given polymer, usually the last works well for cleaning purposes. Of course, such solvent must be clean in order to avoid adding contamination.
Dear all, it contains distinct polar and apolar sites, something that is needed for cleaning by breaking the interfaces in a similar way or mechanism found in surfactants. Besides to this the small size of the molecule allows fast diffusion at the interfaces to do the task. Regards
Victor H Ponce hello Sir
the Ethanol solution is one of the solvent
