Sorun Belirtisi
Product shows silver streaks, bubbles or decreased mechanical properties, related to improper raw '2079851475616104451 treatment
Neden Analizi
Drying temperature or time insufficient, moisture content exceeds standard
Drying temperature too high (exceeding the 75-85°C/3-4h recommended upper limit) causing oxidation
Drying equipment dew point insufficient, poor drying effect
Exposure time too long after drying, re-absorbing moisture
Cellulose acetate butyrate moisture content 0.30% requires full drying
Çözüm
Fully dry under 75-85°C/3-4h conditions
Control drying temperature to avoid overheating
Ensure drying equipment dew point ≤-30°C
Use as soon as possible after drying to avoid exposure
Cellulose acetate butyrate moisture content needs ≤0.02% (injection)/≤0.05% (extrusion)
Temel Çıkarım
Drying requires strict control of conditions according to material characteristics
