PC moisture regain after drying
문제 현상
Qualified dried pellets show silver streaks again after being placed in the hopper for several hours
원인 분석
PC pellets exposed to high-humidity environments after drying will quickly regain moisture, and can absorb excessive moisture within a few hours at room temperature; ordinary hoppers have no heat-preservation drying function, and pellets continuously absorb moisture during their stay
해결 방법
①Use a heat-preservation drying hopper to maintain 80-100℃; ②Pellets stay in the hopper for no more than 2 hours; ③Small-batch feeding, drying matched with production rhythm
핵심 요약
Qualified drying is only the starting point; preventing moisture regain is as important as drying; heat-preservation hopper plus time-limited use is the standard configuration for preventing moisture regain；After confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence
