This article examines the resistance of corrosion-resistant polymeric materials to chemical reagents and the degree of corrosion, taking into account the direction of corrosion processes. One of the main factors that determined the corrosion rate is air humidity and dust released into the atmosphere during industrial emissions. Mixtures based on polymer materials can be used to gum up chemical apparatus and equipment; for corrosion protection, expensive materials are required. The sample is conditioned for 30 months at (23 ± 2) 0С, relative humidity (50 ± 5) %, and the thickness of the sample is determined. Resistance to chemical reagents the change in mass of samples of polymeric materials at a temperature of 35 0C for 3 months was analyzed. It was also found that by determining the corrosion rate (grade St3) by storing steel plates in a different exposure environment for 50 days. As a result, the corrosion rate of steel anti-corrosion coatings is lower than the control sample. According to the data obtained, it was found that the chloro-sulfonated polyethylene compositions are resistant to various organic solvents, acids, alkalis, oxidizing agents, and others.

The article presents the results of research on the development of compositions and the study of the properties of heterocomposite materials for coatings used for equipment for the collection, storage and transportation of oil and oil and gas products protected from corrosion and hydro abrasive wear. On the basis of the analysis of the existing devices characteristics for the mechanical activation of mineral particles, the mechanical activator installation “System of running drums” was developed. Using Newton’s interpolation formula and Lagrange’s method, trigonometric and functional factors were determined, regression equations were derived, which were used to determine the optimal type of filler and the quantitative effect of the compositions and properties of composite coatings and the exploited aggressive environment influence on the properties of the material. Analysis of the results of theoretical and practical research on the rational use of natural minerals can be used as a scientific basis for the targeted use of physicochemical phenomena, in particular priority factors such as the formation of positively and negatively charged particles on the surface of the filler-binder phase division.
