SMMA Drying Management Misconceptions
Problembeschreibung
SMMA dried according to PMMA standards leads to over-processing, or silver streaks occur when drying is needed but not done.
Ursachenanalyse
That SMMA needs no drying in most cases is an important advantage; but drying is still needed in high-humidity environments or when packaging is damaged; excessive drying wastes energy; no drying produces silver streaks and bubbles.
Lösung
①No drying needed for normal production; ②80-90℃×2-3 hours when high humidity or packaging damage; ③sampling inspection of moisture content; ④sealed storage to prevent moisture absorption.; after adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
Wichtigste Erkenntnis
SMMA drying management must grasp the boundary between 'not needed' and 'needed'; sampling inspection is the judgment basis; sealed storage is prevention.; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence
