PC production environment humidity
Sorun Belirtisi
The silver streak rate of PC parts produced in the rainy season is significantly higher than in the dry season, different results with the same parameters
Neden Analizi
Increased environmental humidity accelerates moisture absorption of pellets after opening the package, increasing the drying load; the combination of hopper exposure time and humidity causes actual moisture content to exceed the standard, converting seasonal fluctuations into quality fluctuations
Çözüm
①Extend drying time in the plum rain season and intensify moisture content sampling; ②Cover the hopper and connect drying air; ③Small packaging of raw materials, used immediately after opening；After adjustment, take continuous samples to verify the effect, and resume mass production only after confirming stability
Temel Çıkarım
Environmental humidity is an invisible variable of PC drying; seasonal process compensation and sealed feeding can eliminate rainy-season quality fluctuations；After confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence
