Carbon fiber infrared heating tube what are the obvious features:

 

Carbon fiber infrared heating tube plus hotline is carbon fiber, carbon fiber resistance coefficient and temperature of the relationship is not very big. University laboratory cold resistance of carbon fiber is larger than normal run time by about 45%. Namely the carbon fiber heating tube power less than the rated power of just starting moment, 5 seconds heating tube at rated power.

 

Therefore, the use of carbon fiber infrared heating tube circuit components do not need to reserve the rated current value, can reduce the cost of some equipment. Tungsten infrared heating wire is tungsten metal heating tube, metal is bigger, the relationship between resistivity and temperature so the cold tolerance of the tungsten wire infrared heating tube and the running resistance are quite different.

 

Of the specifications of the heating tube starts, due to the resistance heating wire is relatively small, through the instantaneous current of the circuit will be relatively large, generally 1.5 times the rated current, but the highest instantaneous current university laboratory data is about 10 times the rated current.

 

Therefore, when a device using tungsten infrared heating tube, circuit electrical components of the rated current value need appropriate is higher than the calculated value. Carbon fiber infrared heating tube is made of carbon fiber. Edison invented the incandescent light bulb has tried to use carbon fiber filament, but due to the manufacturing level too backward, he chose the tungsten wire. Carbon fiber is a kind of non-metallic materials, at very high temperatures with physical and chemical properties.

 

Carbon fiber is a kind of special fiber is given priority to with carbon, the carbon content in different type varies, usually over 90%. Carbon fiber has the general characteristics of carbon materials, such as high temperature resistance, resistance to friction, conductive, thermal conductivity, corrosion resistance, etc. But unlike general carbon material, its obvious anisotropy, appearance, soft, can be processed into a variety of fabric, high strength along the fiber axis. The proportion of carbon fiber is low, so than high strength.
