(57) Abstract:Usage: for thermal insulation of dwellings, for protective clothing used in extreme temperatures, to preserve heat in the pipes. The essence of izobreteniya: fabric consists of seven layers, the middle layer is electrically connected to a source of electric current, adjacent the insulating layer is made. One of the layers is made in the form of screen grid to ground electromagnetic radiation. The outer layer is made of a heat-reflective fabric. 1 Il. The invention relates to multilayer materials with electric and can be used for the manufacture of clothing.The multilayer material can be used in extreme temperatures at low temperatures and at high temperatures for protection in case of fire valuable equipment for thermal insulation warm living spaces, eliminating unnecessary heating in the premises in a hot climate, insulation of pipes with fluids.Known multi-layer material containing United dielectric heat-resistant elastic adhesive woven layers, the inner of which is made elektroprovodnyi to the technical essence and the achieved result.However, the construction material is not provided for eliminating the effects of electromagnetic radiation. In addition, the material has insufficient thermal insulation from the environment.The technical result of the invention is to reduce the influence of electromagnetic radiation and the increased insulation from the environment.To provide this technical result is a multilayer material containing United dielectric heat-resistant elastic adhesive woven layers, one inner of which is made conductive, and the adjacent insulating additionally has a layer that is made in the form of screen grid to ground electromagnetic radiation, at least one of the outer layers is made of heat-reflecting material.The proposed material is shown in the drawing.Multilayer material consists of seven layers that are glued together.The first layer of heat-reflecting layer facing the reflecting surface heat inside.The second layer of fabric with the function of reinforcement. It must be strong enough to tear, flexible in all directions. If Mogol is owaka.The third layer is an electrically conductive layer. Ability to withstand temperature depends on the functional purpose of the material. The outer and inner sides of the third layer should be reflecting badly and teploispolzuyushchie.The fourth insulating layer, ground regular components of the parameters of the electric current.The fifth layer shielding mesh for grounding the electromagnetic radiation when passing through the third layer frequency components of electric currents of different nature.Sixth layer protective layer for protection of the working layers from mechanical damage.The seventh layer protective layer for protection of the working layers from mechanical damage, as well as for additional insulation material from the environment.When a heat insulation heat or volume of the fabric should be turned to the third layer to the warmer body.In accordance with the second law of thermodynamics heat supplied additionally from the outside, will be distributed evenly around the third layer, and therefore, the supply of additional heat by passing electric CLASS="ptx2">Fastening seven layers of fabric glue should be after drying, elastic, flexible in all directions, dielectric.At to1> to3because thermal conductivity of the material of the active layer and its heterogeneity, and heterogeneity or variability to1and to3in the layer will be isothermal, continuous thin shell with the same temperature toiistand as the distance from the inner volume or Teploenergo body on the working layer temperature toiistwill decrease. When you pass an electric current on the working layer of the original dynamic picture of insulated shells in the working layer of fabric special will be broken.In the thickness of the material of the active layer creates a shell in which the temperature to= to11+ towill be larger than the temperature to11the inner layer of the shell 5, if you go to the right drawing of Fig.1.This means that ways of passing heat from the internal volume, in relation to the working layer, will be a barrier or boundary, which can justifiably be called adiabatic.IP the additional input of heat into the working layer of the multilayer material. Alternating current can also be used to input heat directly without straightening, but with the adiabatic properties of the working layer may be violated due to the fact that an alternating current reverses its polarity and for one period of the twice reduced to zero. When the difference in temperatures to1and to3the increase in AC current transfers adiabatic shell in the discharge of the heating membranes and makes multilayer material elektropenis, because the increase in current at constant load means an increase in potential difference at the input of the load. Therefore, to increase the practical use of fabric special, I mean first of all the temperature difference to1and to3it is better to use a constant current. From the properties of adiabaticity, the multilayer material can be used not only for heat preservation, in particular in volume, but also to save just the temperature in the volume or body. The temperature can be negative, and the temperature external to teploizolirovat volume may vary within wide limits. Consequently, the multilayer material can be very saisonale pipes with coolant, etc. You can, for example, to insulate the wall in the bathroom, strengthening tightly on the wall like a carpet multilayer material by connecting it through a rectifier and a current controller for a household electrical outlet. On the basis of the material to make a thermos. The material of the active layer can be varied, as long as it was conductive. Previously, the author can recommend the aluminum, the aluminum foil. You can create a layer using the already widely used method of deposition of aluminum or other metal on a solid, reinforcing fabric. Multilayer material containing United dielectric heat-resistant elastic adhesive woven layers, one inside of which is made conductive, and the surrounding dielectric, characterized in that it further has a layer that is made in the form of screen grid to ground electromagnetic radiation, at least one of the outer layers is made of heat-reflecting material.
FIELD: manufacture of protective overalls.
SUBSTANCE: protective clothing is made in the form of isolating clothing combined with spacer system for separating said clothing from user's body. Spacers are made in the form of three-dimensional members distributed over inner surface of isolating clothing.
EFFECT: reduced weight, increased flexibility, enhanced reliability in usage, convenient wearing and reduced production cost.
FIELD: protective clothing.
SUBSTANCE: moisture-proofing outfit is manufactured from water- and air-impermeable material having parts equipped with devices adapted for counteracting undesirable water and moisture effects and connected into single article. Outfit parts are assembled from members connected with one another and made in the form of hexahedrons. Upper and lower parts of each hexahedron are not connected with other parts of outfit and define air-exchanging pockets closed with upper and lower flaps. Free part of perimeter of each flap has second-order line shape and its height is at least 1/3 the distance between two parallel faces of hexagonal members with width equal to length of face.
EFFECT: intensified air-exchange with environment and provision for preventing water from penetration into internal part of outfit.
