T/CEAC 084-2024 Carbon fiber and raw material metal element content degradation microwave digestion method
Basic Information
Scope
Scope: This document specifies the terms and definitions, method summary, reagents, instruments and equipment, method steps, and precautions for the microwave digestion pretreatment of metal elements in polyacrylonitrile-based carbon fibers and raw fiber samples using the microwave digestion method. This document is applicable to the digestion of potassium, calcium, sodium, magnesium, iron, and silicon elements in raw fibers and carbon fibers made from acrylonitrile as the raw material. The digestion of other trace elements in polyacrylonitrile-based carbon fibers and raw fibers can be referenced for use. Main technical content: This document specifies the terms and definitions, method summary, reagents, instruments and equipment, method steps, and precautions for the microwave digestion pretreatment of metal elements in polyacrylonitrile-based carbon fibers and raw fiber samples using the microwave digestion method.
