Method for controlling carbon fiber paper property and carbon fiber planar heating element made of carbon fiber paper with controlled property

摘要

In the present invention, the content of the dispersant is adjusted in an average of 0.2 to 1% by weight based on the total weight of the dispersion solution, the content of the binder is adjusted in an average of 0.01 to 0.03% by weight based on the total weight of the dispersion solution, and the content of carbon fibers is adjusted in an average of 0.01 to 0.03 wt% based on the total weight of the dispersion solution, and the physical properties of carbon fiber paper (carbon fiber dispersion, carbon fiber paper mass, carbon fiber paper basis weight, carbon fiber paper thickness, carbon fiber paper surface resistance) , the carbon fiber paper controls the surface heating temperature, etc.). By manufacturing the planar heating element with the carbon fiber paper whose physical properties are controlled in this way, the disadvantages of the conventional planar heating element can be solved.
