Fiber content inspection inaccurate
문제 현상
The fiber content measured by the ashing method fluctuates from the formulation value by >3%
원인 분석
PP does not pyrolyze completely during ashing, leaving carbides causing high mass; the glass fiber itself loses mass during high-temperature ashing (>600°C); sampling representativeness is insufficient
해결 방법
Standardize ashing conditions (constant temperature at 550°C for 2 hours); use TGA (thermogravimetric analysis) to accurately measure each component; take samples at multiple points and mix to improve representativeness
핵심 요약
Fiber content is the core indicator of LGFPP quality inspection, and the inspection method needs to be standardized
