  • Determination of adhesion by digital image processing of surface coatings

    A program has been developed that allows to evaluate the adhesion of paint coatings by means of analyzing images of the surface of coatings with delamination’s from the substrate to be protected. The program is written in Kotlin using JavaFX platform and is focused on tests carried out by the method of lattice cuts within the conditions of paint and varnish production. Through the work the evaluation of the area of the coating detachment from the surface to be protected is being held and the obtained result is scored by points according to the method of lattice cuts. The use of the program does not require a large computing power of the computer and reduces the time for obtaining the calculating results for one sample from 20 minutes to 3 seconds.

    Keywords: adhesion, lacquer coatings, notch method, Kotlin language, JavaFX

  • Complex approach towards the calculation of technological parameters influence onto Na-CMC rheological properties for drilling agents

    The possibility of getting natrium-carboxymethylcellulose with given viscosity from different raw materials for oil industry is shown in the paper. The regression model, connecting rheological characteristics viscosity with parameters of the technological process is proposed. The program for IDE Microsoft Visual Studio medium which may be used for calculating Na-CMC synthesis parameters, providing the given in the frames of the technological process viscosity value, is developed.
