The objective of this work was to investigate the behaviour of some model surfactants used in the deinking process, namely, sodium oleate and two ethoxylated nonionic surfactants (C12E6 and C14E6) as well as to investigate the suitability of various model substrates for mimicking interactions in technical systems. The influence of the adsorption to the air – water interface has been measured by...

In this study, different coatings (gray epoxy primer, white varnish and red alkyd paint) of 7075 aluminum alloy are cleaned with a 500 W continuous-wave (CW) fiber laser. We analyzed the influence laser power density on temperature evolution target surface morphology. Under condition continuous irradiation for 1 s, experimental results indicated that suitable cleaning thresholds primer varnish,...
