There are many types of heating wire, we have talked about before, here will not be listed one by one, our factory produces a variety of heating wire are mainly metal for heating sheet, in which there are symbolic polyacrylonitrile, carbon fiber material, PET, biomica, silicone five series of products .

With metal, carbon fiber, silicone as the heating plate/sheet , can reasonably improve the output power reliability of the wire, at the same time in the thermal transformation level is also significantly more than other materials to do a lot, metal resistance wire is based on the auxiliary design design scheme, the dimensional tolerance is very small, so the temperature difference in the same piece of electric heating wire can basically be ignored. The heating wire of the metal plate has many advantages over the traditional electric heater .

　　1.Service Life:

　　The buried heating makes the internal metal resistance wire of the heating wire not easy to be oxidized, there is no fire in the work, it is not easy to be fell hotting as line be red , then effectively improve the service life of the heating wire .

　　2.Carbon Fiber Suitable Working Voltage :

　　No telephone design the electric carbon fiber heating wire , working voltage from 220V to 7.4V can be safe to use, can avoid the cable sheath after cracking electrical injury and other conditions .

　　3.Excellent Electric Touch Performance:

　　The electrical contact performance of home appliances----is the key index value of commodity performance. The metal heating wire conductive heater is a metal plastic film, current-carrying strip of the hot-wire is a thickened metal strip, which can bear significant current flow, because the metal heating-wire conductive heater and the thickened current-carrying strip are the same metal, the loop resistance is small, the total contact area is large, and there is a little touch. Metal substrate and current carrier with potential difference, good performance of household appliances, no bad contact phenomenon, hot, spark discharge condition, long-term operation without product quality problems .

　　4.Self-Limiting Temperature (PTC) Features :

　　We all know that the metal itself will have self-limiting temperature characteristics, when the temperature rises the resistor expands, its own output power is reduced,temperature rise is limited, and the ring Da wire includes metal positive ions with high positive temperature index on the original characteristics of the metal, further improving the self-limiting temperature characteristics. The self-limiting temperature characteristic of the metal heating wire is mainly manifested in that the temperature of the metal hot wire is faster than that of the printing ink heating wire at room temperature, and the output power and current are reduced when the temperature rises to the design formula value. This is because the output power of the metal heating wire is large at ultra-low temperature, the heating is rapid, output power is reduced at high temperature .

　　5.Silicone Insulation Performance:

　　The ground resistance is more than 500MΩ, and its resistance value is maintained for a long time in a wide temperature and operating frequency area, has good resistance to high voltage arc discharge and arc discharge .

　　6.Safety Factor On Application:

　　The internal resistance wire of the heating wire manufactured by our factory , all packaged in the middle of the relatively high insulation layer material, wiring position of the power plug is also specially solved, which is not easy to produce power failures and other conditions , At the same time, we pass various performance tests at the factory .
