Near- and mid-infrared optical coherence tomography (OCT) is evaluated as a non-destructive non-contact reflection imaging modality for inspection of industrial marine coatings. Near-infrared OCT was used to obtain high-resolution images (~6/2 µm lateral/axial) hidden subsurface cracks defects in resin base coating, which had been exposed high pressure temperature study coating degradation host...

ABSTRACT. Acrylated Parkia biglobosa medium oil alkyd prepared by the reaction between an acid containing acrylic copolymer and a monoglyceride followed by the addition of polyol and dibasic acid has been investigated for improved properties. The results revealed that acid functional acrylic copolymers containing maleic anhydride as a functional co-monomer can successfully be used to modify alk...

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...

Abstract The present study focuses on the Preparation of Aluminum Oxide, and Copper oxide antifouling coatings to prevent or reduce corrosion fouling in ships marine vehicles. Al 2 O 3 CuO nanoparticles were prepared using ball milling process. nano paints these as pigment linseed alkyd resin a binder. Mild-steel specimens coated with paint immersed seawater for 120 days properties studied Scan...

The high cost of energy resources requires implementation high-efficient techniques for production. In order to successfully solve the problem intensification, resource and saving in production processes alkyd resins, electric heaters technological flowsheet was proposed. A high-temperature ceramic with heat resistance proposed its thermal conductivity coefficient estimated working conditions. ...
