PARA Moisture Absorption Management
Sorun Belirtisi
PARA products have high moisture absorption; amorphous regions molded with low-temperature molds absorb water, causing performance changes.
Neden Analizi
When PARA mold temperature is below 120°C, product moisture absorption is higher; large amorphous region proportion absorbs water; dimensional and mechanical property changes; ambient humidity influence.; during on-site troubleshooting, verify item by item according to this mechanism, avoiding blind machine adjustment based only on experience
Çözüm
①Mold temperature ≥120°C to reduce moisture absorption; ②Ambient humidity management; ③Performance verification after moisture absorption; ④Sealed package storage.; after adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
Temel Çıkarım
PARA moisture absorption management is directly related to crystallinity; high mold temperature is prevention; environmental control is auxiliary.; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence
