- Аннотация: At present, in the process of utilization of powerful explosives, a valuable intermediateproduct, a detonation charge, is formed. Its transformation into detonationnanodiamond under industrial conditions is carried out by the liquid method insuperheated nitric acid (260 ° C, 90 atm). In the present work, the development of agas-phase method of phase and chemical purification of a detonation charge is carriedout. The developed method, carried out in contrast to the industrial one in three stages,has technological and environmental advantages: no loss of a finer fraction ofdetonation nanodiamond (DND) and the formation of only solid waste.The DND obtained by the laboratory method was applied as an active component to apreviously developed anti-icing agent that prevents ice accumulation, especially inextreme weather conditions characterized by prolonged precipitation in the form offreezing rain, as well as critical thermodynamic parameters of the atmosphere. In thecourse of the work carried out, the positive effect of DND on the operation of the antiicingcomposition was revealed, within the framework of improving both the physicaland chemical properties of the substance applied to the surface. A feature of thecomposition modified by DND is that nanostructured particles of diamond and siliconoxide, in conjunction with polymers, create such a crystal lattice on the surface of thematerial to be coated that, compared to the composition without detonationnanodiamond content, the following properties are improved by more than 30%: Antiicingeffect, Oleophobicity, Hydrophobicity, Improved anticorrosion properties,Protection of the surface from chemicals (salts, acids, alkalis), Protection from theeffects of flora and fauna, Improved heat-resistant surface properties. In addition, ahigh strength film is formed on the surface (10H on the Moss scale).
