문제 현상
Obvious irritating odor in the PVA processing workshop
원인 분석

해결 방법
1) Control processing temperature within the PVA recommended range to reduce decomposition; 2) Strengthen workshop ventilation and exhaust; 3) Add absorbent to neutralize odor
핵심 요약
Large odor is caused by PVA decomposition and volatilization; temperature control and ventilation are the key
