Abstract

Abstract: Cellulose acetate filter rod is the most mature and widely used filter material for cigarette development, but it is difficult for cellulose acetate to degrade in natural conditions. Orthogonal experiment is applied to simulate the degradation environment of different filter rod soil burial method by using temperature, humidity, pH value and degradation time in this paper. The results showed that the cellulose acetate filter rod with uncoated wrapping paper could reach the maximum degradation rate of 33.78% in the orthogonal design experiment when the temperature was 40 °C, the relative humidity was 20%, the pH value of soil was 6.0, and the degradation time was 28 days; the cellulose acetate filter rod with uncoated wrapping paper could reach the maximum degradation rate of 33.78% in the orthogonal design experiment when the temperature was 40 °C, the relative humidity was 20%, the pH value of soil was 5.0, and the degradation time was 28 days, and the highest degradation rate of n-ca filter rod was 35.56%.
