Vilka är detaljerna i den energibesparande långt infraröda uppvärmningsspolen?

Energy-saving heating coils now also include nano infrared heating coils, far infrared heating coils, nano heating coils, etc., which are essentially infrared heating coils. After the infrared energy-saving heating coil is connected to the alternating current through the resistor wire, it becomes a far infrared radiation heat source, which has the characteristics of high strength, high thermal efficiency, high penetration, and low energy consumption. The infrared radiation heating technology is pollution-free to both the heated workpiece and the environment. Therefore, the high infrared radiation heating tube is a "green product" in a sense. Its working principle is: when the current passes through the heating wire of the heating tube made of special materials, the heating tube radiates infrared rays of a certain wavelength. When the infrared rays are absorbed by the object, the object is heated. The technology of heating objects with this characteristic is called infrared radiation heating technology. According to the absorption of different wavelengths of infrared light by different materials, in order to adapt to different heated objects, infrared Strålning av olika våglängder kan erhållas genom att ändra materialkompositionen och lindningsmetoden för den uppvärmda tråden .

At present, industrial infrared radiation is mainly short-wave with a wavelength of 0.76~1.6μm, medium-wave with a wavelength of 1.6~4μm, and long-wave with a wavelength greater than 4μm. Short-wave infrared radiation is also called near-infrared radiation, and medium-wave Infraröd strålning kallas långt infraröd strålning . Den termiska inertien hos infraröd strålning är mycket liten och den termiska effektiviteten är mycket hög . Därför kan användningen av kortvågs och medelvärde och korta infraröd strålningsteknik värme med hög densitet, hög energi och hög intensitet, där byförbättring av värmevågsinterktiden och den korta tidpunkten. Uppvärmningstemperaturen för Weichuan-infraröd energibesparande uppvärmningsspole, som är välkänd på marknaden, når 500-700 grader, och den långt infraröda emissiviteten når mer än 90%. Samtidigt matchar det infraröda strålningskällmaterialet för det Weichuan infraröda energibesparande uppvärmningsspolen de fysikaliska egenskaperna hos kol-krom-molybden-legeringsmaterialet som för närvarande används i formsprutningsmaskinen, vilket gör att energibesparande uppvärmningsspolen har bättre energibesparande effekt än andra liknande produkter.

Due to the obvious tendency of full electrification of injection molding machines, the use of servo systems makes the energy consumption of electric heating systems exceed 30% of the total energy consumption. If different types of heating coils can be reasonably selected, energy consumption can be reduced, thereby reducing production costs. The resistive heating coil refers to the heating of the resistance wire, which transfers the heat to the barrel by contact heat conduction. Only the inner wall of the heating coil transfers heat energy, while the heat of its outer wall is mostly dissipated into the air. Due to the problem of thermal balance, the outer surface temperature is consistent with the working set temperature, which is above 200~300℃, and there is a large heat loss. However, the main body of the electromagnetic induction heating coil does not heat up. In actual use, a certain thickness of thermal insulation material will be wrapped outside the barrel. The surface temperature of the barrel of the electromagnetic induction heating coil is lower than 60 degrees Celsius, and the heat radiation in the barrel is very small, the heat energy loss is very small, and the thermal efficiency is very high, so the energy saving effect is obvious. The infrared heating coil is an infrared generator composed of excellent resistors and quartz tubes. It can heat the workpiece with high density, high energy and high intensity. At the same time, it adopts a reflective structure and the application of aerospace-grade insulating materials to improve the efficiency of infrared radiation, reduce heat energy förlust och uppnå betydande energibesparande effekter .
