PA6 Plum Rain Season Compensation
Sorun Belirtisi
With the same set of process parameters, the silver streak rate of products in the plum rain season is significantly higher than in the dry season
Neden Analizi
In the rainy season, ambient humidity soars, the moisture absorption rate of pellets after opening doubles, and the drying load increases; the original drying time is no longer sufficient in the high-humidity season to press the moisture content below the red line
Çözüm
①Extend the drying time by 1-2 hours in the rainy season and increase the frequency of moisture content sampling; ②cover the hopper and connect dry air; ③dehumidify the workshop to lower the ambient humidity baseline; after adjustment, continuously sample to verify the effect, and resume mass production after confirming stability
Temel Çıkarım
Seasonal humidity is an invisible variable in the PA6 process; rainy-season compensated drying plus enclosed feeding keeps weather factors outside the quality gate; after confirming effectiveness, fix the parameters and practices into the work instructions to prevent recurrence
