Corrosion of ETFE screw and barrel

문제 현상

Corrosion appears on screws processing ETFE

원인 분석

Corrosion of metal by HF from slight decomposition of ETFE

해결 방법

Use fluorine corrosion resistant alloys (Hastelloy, Monel); chrome plate or special coating on screw surface

핵심 요약

ETFE processing has extremely high fluorine resistance requirements for equipment materials
