加快环境中烟用滤嘴的生物降解

本文通过在复合嘴棒中添加高分子聚合物和生物降解促进剂,提高了卷烟滤嘴在自然环境中的降解速度,采用不同时间段内的重量损失和电子扫描三维照片试验与普通嘴棒降解速度进行对比,效果显著。进一步试验发现,上述添加剂在不改变吸味的基础上,具有良好的降焦效果,降焦率达到2 5%~30%。 

Accelerated biodegradation of cigarette filters in the environment

With the problem of "smoking and environment", the biodegradability of cigarette butts in the environment is of great concern to the general public. Based on the cigarette butts biodegradation mechanisms, the paper, through the addition of synthetic polymer and special subsidery additive into the dual-composite filter, offers and effective method for overcoming two major obstacles during the process of biodegradation, i.e. restriction of plugwraps, tipping papers and plasticizer and deacylating speed of cellulose acetate tow. The proposed method can be easily realized by using currently available technology, and also especially suitable for the filter disposed to the adverse environment of biodegradation. Further experiments indicate that the additives mentioned above can reduce cigarette tar delivery up to 25%~30% without changing the taste of the smoke.
