Elastomer materials for application in equipment
of subsea production systems
M. V. Korobchuk
The development of systems for subsea production of hydrocarbon resources for Russia is a new direction. The article describes the elastomeric materials used for the manufacture of seals for movable and fixed joints. It was noted that at present there are no domestic standards governing the requirements for elastomeric materials used in mining equipment. Based on the analysis of foreign experience, information is provided on rubbers that are most widely used in the design of subsea production systems. For basic rubbers, their main properties are considered. For rubber compounds that have become widespread and have proven their efficiency in practice, some characteristics are given. Based on the information presented in the review, a conclusion is made about the need to develop formulations of domestic elastomeric compositions.
Keywords:elastomers, elastomeric composition, rubber, shelf, hydrocarbon production, subsea production system.

Radiation changes in the nanostructure
of graphite-like boron nitride and monitoring
of the temperature of in-channel reactor irradiation
E. I. Isaev, V. A. Stepanov, V. M. Chernov
Graphite-like materials, due to the strong anisotropy of the crystal structure, are microscopically different-modular, i.e. they have significantly different elastic resistance to tension and compression at the subatomic level. As a result of microscopically different-modular the crystallite microdeformations unavoidable in ceramic materials cause large shifts and non-uniform broadening of X-ray lines. Reactor irradiation changes both the magnitude of microdeformations and the microscopic different-modular of graphite-like nano-structured materials. The microscopic different-modular of boron nitride ceramics is analyzed by X-ray line decomposition (00l) using Lorentz functions. In pyrolitic materials (very microscopically different-modular materials) it is necessary to use approximation by Poisson distribution of X-ray lines rearranged in dimensionless coordinates (00l). A method for determining temperature during high dose (up to 3∙1023 n/cm2) high-temperature (up to 1800 K) reactor irradiation of material science containers using pyrolytic boron nitride monitors is described. The method uses the relationship between the magnitude of induced microscopic different-modular of the material and the irradiation temperature.

Preparation of copolymer of allyl ester
of salicylic acid with styrene and study
of its antifungal properties
L. Sh. Abbasova
The reactions of radical copolymerization of the allyl ester of salicylic acid with styrene were carried out and their patterns and products were studied. The Feinemann-Ross method was used to determine the constants of the relative activity of the copolymers (r1 = 0.02 and r2= 9.6) and the parameters of the microstructure of the obtained copolymers. It was found that with an increase in the styrene content from 10 to 90 mol. % in the initial mixture of monomers, the average length of microblocks consisting of styrene units increases from 2.07 to 87.4, the length of microblocks of allylsalicylate units practically does not change, and the Harvurd constants decrease from 61.60 to 2.26. The results of studying the composition and structure of styrene and allyl salicylate copolymer samples under various conditions, as well as the values of the copolymerization constants and microstructure parameters, show that the copolymer macromolecules have a statistical structure, include allylsalicylate fragments and styrene microblocks. Studying the antifungal properties, it was found that the investigated copolymer of allyl ester of salicylic acid with styrene possesses such properties. Micromycetes such as Aspergillus niger, A.ochraseus, Penicillium cuclopium, Cladosporium herbarium, Fusarium moniliforme and F.oxysporium were used as test cultures.
Keywords:allyl salicylate, copolymerization, styrene, copolymerization constants, parameters of the microstructure of copolymers, antifungal properties.

The mechanism of high-temperature creep deformation during compression tests of binderless tungsten carbide specimens with different initial particle size was studied. Tungsten carbide samples with high relative density (96.1 – 99.2 %) were obtained by high-speed spark plasma sintering (SPS) from nano-, submicron-, and micron-sized α-WC powders. The creep tests were carried out in two modes: isothermal soaking at different temperatures (1300 – 1375 °C) at a given stress, allowing to estimate the activation energy of creep, and tests by “stress jumps” at 1325 °C, allowing to estimate the value of the coefficient n in the creep equation. It is shown that the value of creep activation energy in ultrafine grained tungsten carbide with grain size ~ 0.15 µm sintered from plasma chemical nanopowders is ~ 31 kTm. This value is 1.5 – 2 times higher than the creep activation energy in fine-grained tungsten carbide samples obtained by SPS from submicron (~ 0.8 μm) and micron (~ 3 μm) industrial powders. It was found that the value of the coefficient n varies from 2.4 to 3.1, which corresponds to the case of motion of lattice dislocations in the field of uniformly located point obstacles. It has been suggested that one of the reasons for the increase in creep activation energy in tests of tungsten carbide is an increased volume fraction of W2C low carbide particles formed during high-speed sintering of plasma-chemical α-WC nanopowders with an increased concentration of adsorbed oxygen.
Keywords: tungsten carbide, powders, spark plasma sintering, creep, deformation, diffusion.

in relation to methane

A new nanostructured carbon material is synthesized, which represents aerogel based on reduced graphene oxide. Aerogel obtained by using supercritical methods for processing a hydrogel in isopropyl alcohol. Resulting material has sufficiently high specific surface in terms of BET — 657 m2/g with high specific pore volume DFT — 0.766 cm3/g, which creates good prospects for its use for the adsorption of energetically important gases, in particular methane. A favorable factor for increasing the rate of adsorption-desorption in such systems is the large volume of mesopores with diameters of about 4.5 – 6.5 nm. Adsorption of methane at temperatures of 298.15, 303.15, 313.15 K and pressures up to 100 bar was studied on the synthesized graphene aerogel. The maximum value of methane adsorption under temperature 298.15 K and pressure of 100 bar reaches 7.31 mmol/g. The characteristic parameters of the adsorption process were analyzed using the empirical models of the Langmuir and Freundlich isotherms. The adsorption process was investigated at the level of evaluating thermodynamic parameters, which indicate its change from a random state to an ordered one, and its exothermic and physical nature. The obtained results can be used in the design of storage systems for adsorbed natural gas.
Keywords:adsorption, methane, graphene aerogel, thermodynamics, porous structure.

The change in the contact angles of wettability by water and glycerin, the work of adhesion, total surface energy, its polar and dispersion components on the time of plasma treatment at the anоde and cathode has been investigated. A significant increase in the hydrophilicity of the polymer surface and a good stability of the obtained characteristics during storage of modified films in air at room conditions are shown. The adhesion properties of the polymer were investigated using T-test method according to ASTM 1876. The data of peel resistance in contact with some adhesives for the initial and modified polymer were obtained. Atomic force microscopy was used to study changes in surface morphology under the influence of the direct current discharge treatment.

A composite material with photocatalytically active properties was obtained by electrophoretic deposition (EF) of highly dispersed anatase on the surface of the carrier. The carrier was a titanium/rutile cermet plate obtained after 2 hours of oxidation at 875 °C. using the oxidative construction approach. During this time, a layer of rutile 15 – 20 μm formed on the titanium plate, which has good adhesion to the surface of the metal core. The breakdown voltage for this sample was ~ 150 V. To make the photocatalyst film homogeneous and compact, it was carried out by 3 cycles of electrophoretic deposition and heat treatment at 395 °C. The photocatalytic activity of the obtained samples was studied using the example of the reaction of catalytic decomposition of ozone under the action of ultraviolet radiation.
Keywords:titanium dioxide, oxidative construction, electrophoretic deposition, nanodispersed photocatalysts, photocatalytic activity.
