ASA drying temperature gradient selection
문제 현상
[Problem phenomenon] Different sources give drying temperatures of 80°C, 82°C, 85°C etc., execution hesitates
원인 분석
The differences among sources lie in equipment and grades: Plasthub recommends 80°C×2-4h, and measured 82°C gear is also common; the commonality is that the temperature is sufficient to drive out moisture without causing agglomeration or discoloration, and pellets have sticking risk above 90°C
해결 방법
Set within the 80-85°C range according to equipment capability; desiccant dryers take the lower limit, ordinary ovens take the upper limit; observe pellet condition to prevent sticking; after adjustment, continuously sample to verify the effect, and resume mass production after confirming stability
핵심 요약
ASA drying flexibly selected within the 80-85°C range, prevent pellet sticking above 90°C; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence
