Study on Mechanical Properties and Micro Morphology of Acetate Filter Rod before and after Partial Degradation
Journal of Physics: Conference Series(2020)
Abstract
Mechanical properties and micro morphology of acetate filter rod before and after partial degradation were studied. In this paper, the mechanical properties and micro morphology of acetate filter rod samples and 28 days soil burying were compared by means of Scanning Electronic Microscopy (SEM), texture analysis, infrared spectrum analysis and thermos-gravimetry (TG) analysis. The results showed that after degradation, the average compression modulus, hardness and elasticity of cellulose acetate filter rod decreased by 15.14%, 15.19% and 0.82%, respectively. The infrared spectrum analysis showed that cellulose acetate was degraded by soil burying method and carboxyl carbonyl was formed, but the degradation degree was not high. The degradation degree of cellulose acetate was lower than that of cellulose acetate before degradation. The weight loss zone between 110 °C and 230 °C is less, which may be due to the complete degradation of the small molecular assistant added to the cellulose acetate degraded by the soil burying method.
