Low-temperature radiant heating film is able to heat the latter powered translucent polyester film, by 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, so that the body and the object first to get warm, and its overall effect is better than traditional convection heating. Low-temperature radiant heating film system consists of power, temperature control, connectors, insulation, electric membrane facing layer. Power connectivity via wire electric film, the electrical energy into heat. Because electric film is purely resistive circuit, so its high conversion efficiency, in addition to a small part of the loss (2%), the majority (98%) is converted into heat electric membrane system components and functions: (1) electric membrane system comprises the following sections: 1, insulation layer 2, reflective film 3, electric film; 4, connecting wires, connection card, insulated cover 5, the thermostat. (2) Electric diaphragm electric diaphragm is the core element of the whole system, this system is a heat generating element. It's the base for special PET polyester film, heating element for a special conductive ink, accompanied by silver conductive metal bus bars and conductive leads, the last under the composite by hot pressing. Electric heating film mainly way of heat radiation, is a low-temperature radiation, it has transparency in the form of infrared heat transfer to the interior exudes. (3) connecting wires to connect the card, insulated hood is electric membrane connecting wires to provide power to the entire circuit loop connecting the card, with the electric insulating cover for part of the film, to ensure safe operation. (4) the entire electric film thermostat to control the system, to ensure the stability of the indoor temperature. Electric film product is connected via a connecting card and thermostat, each film are connected in parallel, and finally unified by a group of lines in series to the thermostat, all joints are sealed in connection card, wire connector part not appear point-laws connect card installation method: ▼ connect card is installed at one end electric film group (the other end with a special insulating tape for insulation treatment). ▼ The center is aligned to connect the card and cover one end of the flow of the carrier. With a special tool a pressure compacted in place. ▼ with special crimping tool to connect the card pressed, flatten the electric membrane, and used as a waterproof insulated rubber M3. ▼ each group of electric film is connected in parallel fashion, with special T-connector cable with the adjacent film group, connecting the mouth with M3 plastic insulation for water treatment, and use the pull method to check 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 the building of the same 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: In 2100 hours aging test, the shrinkage of less than 2%. Stable performance: Tested, 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 the diaphragm between full 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 film at -20 ℃ environment in repeated bending and tensile test, no breakage, maintains its 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 the human body: radiant heating products by the national authorities to detect infrared applications experts, 8-14 micron wavelength in the infrared part of which has a special role in human health, the wavelength range of scientists known as the "lifeline". It can be quickly absorbed by the body, so microvascular expansion, promote blood circulation and metabolism, activation of cells, enhance immunity, is very beneficial to health.
