Low-temperature radiant heating film can heat the latter powered translucent polyester film by a special conductive ink, metal carrier, as amended, processing, hot pressing between the insulating polyester film. When working with electric film heating element, the heat in the form of radiation into space, the body and the object first to get warm, the combined effect of better than traditional convection heating. Low-temperature radiant heating film system consists of power, temperature control, connectors, insulation, electric membrane facing layer. Power supply via wire communication electric film, the electrical energy into heat. Since the electric film is purely resistive circuit, so the high conversion efficiency, in addition to a small part of the loss (2%), the vast majority (98%) is converted into heat electric membrane system components and functions: (1) electric membrane system comprising the following sections: 1, insulation layer 2, reflective film 3, electric film; 4, connecting wires, connection card, insulating cover 5, the thermostat. (2) Electric Electric diaphragm membrane is a core element of the whole system, the heat generating element of this system. Its special polyester film substrate is PET, the heating element for the special conductive ink, accompanied by silver paste and conductive metal bus bars of conductive leads, the last under the composite by hot pressing. Electric film heating mainly in the way of heat radiation, a low-temperature radiation, which has transparency in the form of infrared heat transfer to the interior exudes. (3) connecting wires, connection card, insulated cover is electric film connecting wires to provide power to the entire circuit loop connection card, the insulating cover is to be with the electric part of the film, to ensure safe operation. (4) Electric film thermostat for the entire system is controlled, to ensure the stability of the indoor temperature. The product is connected via electric film thermostat connection card, each film are connected in parallel, and finally unified by a group of lines in series to the thermostat, all joints are sealed to the connection card, the wire section can not appear connection points. Attached connect card installation method: ▼ connect card installed in one end of the electric film group (the other end with a special insulation tape for insulation treatment). ▼ aligned with the center connected to the card and cover one end of the flow of the carrier. The pressure with a special tool to compress in place. ▼ with special crimping tool to connect the card pressed, flattened to electric film with M3 glue for waterproof insulated. ▼ Each group electric film is connected in parallel, with the special T-connector cable with the adjacent film group, connecting the mouth with M3 plastic insulation for water treatment, and use the pull method of checking the wire connections are secure. Features aging: materials are specially dedicated electric film material with good properties, anti-aging, non-degenerate, stable performance, service life and building age. Moisture resistance: electric film as a whole is waterproof, resistant to 48 hours after flooding more than 1000V high voltage test, its performance was normal and no leakage phenomenon. It can be used in wet environments, but do pay attention to the connection portion and insulated waterproof cut portion. Shrinkage is small: in 2100 hours of burn-in test, the shrinkage rate of less than 2%. Performance and stability: After testing, electric film on the surface temperature reaches 40 ° C the state, 26,000 hours of continuous operation, performance and size unchanged. Adequate heat: advanced thermal bonding process, so that between the membrane sufficient polymerization, no bubbles, can not afford to layer, the heating element to ensure the close integration with the carrier strip. Wide tolerance: electric membrane can be safely run at -20 ℃ -80 ℃ of environment. Tested: electric membrane environment of -20 ℃ repeated bending and tensile test, no breakage, still maintain their soft, durable performance. Advanced technology: Security: after power electric film, the surface temperature not exceeding 40 ℃ -50 ° C, not spontaneous, not self-destruct, no leakage. Beneficial to human body: radiant heating products by the national authorities detect infrared application experts wavelength of 8-14 microns, in the infrared which belong to human health have a special role, the wavelength range by scientists known as the "lifeline". It can be quickly absorbed by the body, microvascular expansion, promote blood circulation and metabolism, cell activation, enhance immunity, it is very beneficial to health.
