Transparency of modified cellulose acetate butyrate significantly decreased
Problembeschreibung
Transparency of modified cellulose acetate butyrate significantly decreased, haze increased, not meeting transparent product requirements
Ursachenanalyse
Refractive index of added additives does not match cellulose acetate butyrate
Uneven additive dispersion produces scattering
Processing temperature too high, additive degradation and discoloration
Addition amount too large, affecting transparency
Crystallinity changes affect transparency
Lösung
Select additives with matched refractive index
Ensure uniform additive dispersion
Control processing temperature to avoid additive degradation
Reduce the addition amount
Control crystallization conditions
Wichtigste Erkenntnis
Transparency decrease needs to be addressed from refractive index matching and dispersion
