The article provides an overview of anticorrosive materials, for which phosphoric and oxyethylidene diphosphonic acids are used. The reasons for the growing interest in them are shown, as well as possible circumstances that led to a decrease in the quality of phosphating primers.
PROCESSING OF POLYMERS AND COMPOSITES
The work presents studies on determining the effect of pigments and fillers on the performance characteristics of coatings. The main physical and mechanical characteristics of the obtained coatings, as well as the results of welding tests, are given. Some criteria for selecting raw materials (epoxy resins, pigments, fillers) for the possibility of carrying out welding work and ensuring the required properties of conversion coatings are identified.
The colloidal chemical principles of the process of obtaining polymer materials by the core– shell method have been studied. The most promising technologies for obtaining such systems are considered. The mechanisms of synthesis of core–shell polymers by emulsion polymerization have been studied. A technology for the synthesis of polymer adhesive-strengthening material has been developed and its quality indicators have been determined. Ways of using new technology for modifying coatings, biting, mastics and other binding materials are outlined in order to improve their performance properties.
PRODUCTS AND RESEARCH
The article presents the results of a study of the microstructure and topography of the surfaces of fluoropolymer coatings after thermal and humidity tests. The influence of tropical climate conditions, variable exposure to high and low temperatures and a humid environment, exposure to elevated temperatures for a long time, as well as humidity and salt fog on the structure and microrelief of the surface of adhered polymer films is considered. Profilograms of coating areas after various accelerated aging factors are presented.
The article considers samples of non-stick welded sprays from various manufacturers. The effectiveness of sprays designed to prevent splashes of molten metal from sticking to surfaces undergoing welding is evaluated. Data on the compatibility of non-stick sprays with epoxy paints, phenolformaldehyde and phosphating primers are presented.
ECOLOGY AND RESOURCE SAFATY
The presented work provides a comprehensive analysis of methods and means of intensification of chemical and technological systems of the coatings industry. The ways of increasing the energy resource efficiency of chemical technology systems in the implementation of engineering and reengineering in the concept of paint technologies are considered. The application of the principles of intensification of chemical and technological systems at operating enterprises is shown.
