FIELD: personal use articles.SUBSTANCE: rescuer combat garment suit comprising elements having flame-retardant properties, and consisting of a jacket with sleeves and a hood with a transparent protective element located in operation state on the head face part, and also trousers with suspenders and tight belt, and boots from the flame-retardant material resistant to mechanical impacts of seismic nature. The fabric for the upper part of the combat garment is used as heat-resistant fabric from yarn of polyphenylene oxadiazol fibre and filament yarn "Rusar", as well as comprising a protective helmet of the company "Cromwell F600" with a high level of comfort, and a protective vest, and the protective vest comprises a fabric lining connected to the protective shell, and in the fabric lining the elastic frame racks are fixed by means of retainers on the waist belt of the trousers, and the protective shell is attached to the elastic frame racks and comprises the inner and outer protective packets between which the gasket is placed, made in the form of a tape with fixed folds arranged at a constant pitch from the side of the protected object, and located sequentially in two outer shell, and the outer packet, facing the environment surrounding the operator, is made multilayered, and each layer is made in the form of interconnected rings, the material of which is used as stainless steel. The layers are located with overlapping of the ring clearance with their articulation, and the inner protective packet is made three layered. The layer in contact with the outer shell and the layer facing the operator's body are made of perforated polymeric material such as aramid fibres, and an intermediate layer located between them is made resilient of elastic mesh elements. The density of the mesh structure of the elastically flexible mesh elements is in the optimal range of values of 1.2 g/cm÷2.0 g/cm. The material of wire of elastic mesh elements is grade steel EI-708, and its diameter is in the optimal range of values of 0.09 mm÷0.15 mm. The protective vest protective shell comprises outer shell layers, for example, of aramid cloth impregnated with a polymer binder, hard-alloy curvilinear or flat-variable inserts and the layers of the inner shell similar to the outer ones, and the inserts are made of elementary cells connected to each other and to the shells by the adhesive chemically compatible with the binder of the shells. The inserts are made of isotropic material such as ceramic, with a minimum linear dimension of the cells twice exceeding their thickness, and for attaching them the elastic glue is used, based on a synthetic elastomer such as cast polyurethane. The cells can be made square and arranged in a staggered manner or in the form of a regular hexagon, and the interconnected rings of stainless steel are processed with the composite material with improved protective properties against electromagnetic radiation, which consists of a polymeric base, in which the particles of compounds - (Fe, Si) or - Co are distributed, having the nanocrystalline structure with the volume density (0.6÷1.4)±101/nm. The polymeric base for fixing the position of the powder particles with a nanocrystalline structure is formed as alternating structural elements located at an angle of 90° to each other, and each of the elements is made in the form of elongated particles arranged in parallel rows, at that the particles located on the left and right from it are shifted by the distance not exceeding half the maximum particle size. The optimal is the following range of values of volume density of nanocrystals in the amorphous matrix: more than 0.6±101/nmbut less than 1.4±101/nm.EFFECT: improvement of operational reliability.3 cl, 10 dwg, 2 tbl |
