ABS production smoke and odor
문제 현상
Obvious smoke and irritating odor appear in the workshop, the product is sometimes accompanied by yellow spots, and operators feel uncomfortable.
원인 분석
Too high melt temperature or local overheating causes ABS to decompose and smoke; too long heat preservation time during shutdown ages the material in the barrel; regrind mixed with many low-molecular substances also smokes; the decomposition products also affect the product quality.
해결 방법
①Verify and reduce the actual melt temperature; ②if the shutdown exceeds 15 minutes, lower the temperature for heat preservation or empty the barrel; ③reduce low-quality regrind; ④strengthen workshop exhaust; ⑤clean the degraded material in the barrel.
핵심 요약
ABS smoking=a clear signal of 'overheating': the temperature must be lowered and checked immediately, production cannot continue with a fault; smoke is both a quality problem and an occupational health problem, and shutdown management must be formed into an SOP.
