Static electricity attracting dust on PET bottle filling lines
문제 현상
High-speed PET bottle filling lines attract dust from the air due to electrostatic effects, affecting hygiene and appearance.
원인 분석
PET surface resistivity >10¹⁶Ω; friction generates static electricity that is not easily dissipated; low ambient humidity aggravates static electricity; conveyor belt material rubs against PET to generate charge.
해결 방법
Increase ambient humidity to 50-60%RH; use ionizing air bars to eliminate static electricity; add antistatic agents.
핵심 요약
PET static electricity problems are prominent in low-humidity environments and require comprehensive antistatic measures.
