AI Technical Summary
Existing cellulose ester materials, especially cellulose acetate, degrade slowly, resulting in environmental pollution, and existing improved methods fail to effectively shorten the degradation time and maintain the performance of cigarette filters.
The coating or pill is formed by adding alkaline material, enzyme material or a combination thereof to the cellulose ester to promote the degradation of the cellulose ester. Alkaline and enzyme materials can rapidly hydrolyze cellulose acetate upon exposure to water, reducing its substitution, thereby accelerating the degradation process.
The rapid degradation of cellulose ester materials is achieved, the degradation time is shortened to 20 days or less, and the degraded material is close to neutral, reducing environmental pollution.
