METHOD OF MEASUREMENT FOR BLEND RATIO IN PEEK+PTFE+C/FIBER USING THERMAL ANALYSIS

摘要

A method for measuring a blend ratio in PEEK+PTFE+C/Fiber is provided to analyze each content of the three materials more accurately through a thermogravimetry analyzer. A content analysis method of three materials in a three-phase blend material comprises the steps of: preparing a specimen for a thermogravimetry analyzer(TGA) by using PEEK-PTFE-C/Fiber blend material; raising the specimen temperature from 30°C to 700°C in the TGA under the nitrogen atmosphere at the raising rate of 5~20°C/min; lowering the specimen temperature from 700°C to 380°C in the TGA under the nitrogen atmosphere at the decreasing rate of 5~20°C/min; raising the specimen temperature from 380°C to 450°C in the TGA under the nitrogen atmosphere at the raising rate of 5~20°C/min; raising the specimen temperature from 450°C to 850°C in the TGA under the oxygen atmosphere at the raising rate of 5~20°C/min; and calculating the content of component.
