Embodiment Construction
[0072] The present invention will be specifically introduced below in conjunction with specific embodiments.
[0073] Various evaluations and measurement methods in the present invention are as follows:
[0074] Residual rate of heat resistance: using a thermogravimetric analyzer (Netzsch, Germany, NETZSCH TG 209F3), in an air atmosphere, the temperature was raised to 400 °C at a heating rate of 10 °C / min, and the resistance at 300 °C was obtained from the obtained thermogravimetric curve. Thermal Survival Rate.
[0075] Emulsion particle size: measured using a laser particle size analyzer (Malvern, UK, Mastersizer 2000).
[0076] Carbon fiber ash content: according to the national standard GB / T 1429-2009 "Determination of Ash Content of Carbon Materials".
[0077] Roller sticking degree in the raw silk production process: continuous production for one month, count the number of times the roller surface is cleaned during the calculation period, and evaluate according to the ...
