After the infrared heating tube is energized, during frequent startup, shutdown and long-term continuous operation, the power is stable within a certain tolerance range without any instantaneous power influence.  

The carbon fiber heating element is a pure black body material with high thermal efficiency, which can save energy by more than 30% compared with general metal heating elements. Therefore, it has the characteristics of fast temperature rise, small thermal hysteresis, uniform heating, long heat radiation transmission distance, and fast heat exchange speed.

In the working process, the luminous flux is much smaller than the metal heating element, and the electric heating conversion efficiency of the electric heating tube is as high as 95% or more (that is, when you use a 1000w ordinary electric heating tube, when you use a carbon fiber electric heating tube, only 700w is needed). 

The parts should be stored in a dry place. If the insulation resistance is lower than 1ω due to long-term storage, it can be dried in an oven at about 200°C, heated with an IR heating tube or reduced voltage, until the insulation resistance is restored. 

The magnesium oxide powder at the outlet of the electric heating tube should prevent the penetration of pollutants and moisture in the place of use to prevent leakage accidents.
