The physicochemical properties of natural gas condensate (GC) have been investigated in order to obtain new competitive solvents with improved quality properties for technical purposes as well as for the production of arenes. The technology of production has been developed and the optimal technological mode of the process of rectification and product development has been determined. A new type of solvents from the new GC raw materials were tested in the production laboratory for quality compliance according to the standards.

The study of the use of domestic nitrile-butadiene rubber of the brand NBR 1845 as a modifier of commercially available paints and varnishes ГФ-021 and XB-0278. The maximum concentration of rubber NBR 1845 was found with a minimum viscosity of the solution in xylene. The stability of modified paint and varnish materials has been tested. The characteristics of the obtained paint coatings were determined in comparison with unmodified coatings.

The article presents experimental data obtained in the study of such indicators of water resistance as capillary suction, water and vapor permeability, softening coefficient, adhesive strength.

Heat resistance of coatings from organosilicate compositions (OSC) OS-51-03 of cold and hot curing from different manufacturers, including two OSC from commercial manufacturers and an OSC developed and manufactured in Institute of Silicate Chemistry (OSC-ISC), is studied. The heat treatment (H/T) of the samples included heating at a rate of 3 °C/min to T=300 °C and exposure at this temperature for 5 hours. To assess the heat resistance, the properties of the coatings before and after heat treatment are compared. It is shown that H/T of coatings from commercial OSC leads to color changes and significant deterioration of their hardness and abrasion resistance. At the same time, H/T has no significant effect on the color and strength characteristics of OSC-ISC coatings. Despite a significant deterioration in the strength characteristics of coatings from commercial OSC, which is probably due to the thermal decomposition of the binding component of OSC, the values of the specific volume resistance of coatings from commercial OSC and OSC-IHS are of the same order of magnitude both in the initial state and after H/T.

The аmerican international standard UL-1709 for testing fireproof coatings for rapid fire exposure is considered. Test equipment for simulating a hydrocarbon fire has been studied. The parameters for which this method is tested are shown. Full-scale and small-scale tests according to this standard are considered. Additional tests that simulate the conditions of environmental impact on the protective material for metal structures are described.

The presented work presents a technique developed by the authors for engineering chemicaltechnological systems, based on elements of mathematical modeling and system analysis. The described approach makes it possible to optimally and efficiently carry out engineering, as well as reengineering of high-intensity paint and varnish industries, which is confirmed by its application at the objects of the paint and varnish industry.
