PET workshop dust contaminating preforms
문제 현상
Fine dust particles adhere to the preform surface, forming pits after bottle blowing, and the situation improves significantly after cleaning the workshop and enclosing the conveying.
원인 분석
Open conveying and manual operations allow dust to adhere to the preform surface; when workshop cleanliness is insufficient, dust is adsorbed with static electricity, affecting appearance and hygiene indicators.; during on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based only on experience
해결 방법
①Enclosed conveying and storage of preforms; ②improve workshop cleanliness; ③eliminate static electricity adsorption; ④reduce direct manual contact.; after adjustment, take consecutive samples to verify the effect, and resume mass production only after confirming stability
핵심 요약
Food-grade preforms have high cleanliness requirements; enclosure and clean workshop management are the common guarantee for hygiene and appearance quality.; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence
