Abstract
Purpose: For optimizing properties of final glasses frame, the aim of this study is to examine the correlation of processing conditions and properties of cellulose acetate (CA) sheets through the investigation of properties of CA sheets prepared under processing steps. Methods: The properties of CA sheets were investigated in terms of different glasses frame processing conditions, bending process, barrel process, and ultrasonic cleaning process. CA sheets prepared through the sequential processing were examined by various analysis: gloss, mechanical properties, thermal properties. Results: After barrel process, hardness and tensile strength of CA sheet were increased. However, bending strength and impact strength were decreased. It is suggested the CA sheet had became rather stiff state (brittle). Also, in degradation temperature region of plasticizer, about 3% of reduction in plasticizer weight was confirmed upon TGA analysis. Conclusions: Glasses frame process, especially in the barrel process have a profound influence on the properties of CA sheet owing to reduction of total amount of plasticizer.
