烟用内衬纸 VOCs与重金属影响因素分析

目的从生产工艺、产品类型等方面分析影响烟用内衬纸VOCs、重金属含量的程度。方法采用气相色谱/质谱联用法和电感耦合等离子体质谱法,对9种类型烟用内衬纸的18种VOCs和6种重金属进行检测。结果产品类型的不同对烟用内衬纸VOCs含量具有明显的影响,尤其是醇类物质,印刷类内衬纸高于未印刷内衬纸1倍以上,同时,随着印刷色数的增加,VOCs含量也成正方向增加;油墨和其他辅助材料对内衬纸重金属含量也有一定影响,尤其是铬(Cr)和铅(Pb)的含量,真空镀铝(转移)内衬纸仅是真空镀铝(直镀)内衬纸和复合铝内初纸的约50%和10%。结论不仅是基纸,而且油墨和辅助材料对内衬纸VOCs和重金属含量也有一定程度的影响。

Analysis on the Influence of Different Parameters on VOCs and Heavy Metals of the Inner Liner

Objective In order to provide some references for the safety control of the inner liner, the production processes and product types were analyzed for their influences on the VOCs and heavy metals of inner liner. Methods Gas chromatography / mass spectrometry and inductively coupled plasma mass spectrometry were applied to determine the 18 VOCs and 6 heavy metals in the 9 types of inner liners. Results By measuring and analyzing VOCs and heavy metals in the 9 kinds of inner liner, different product types showed obvious impacts on the VOCs of the inner liner, especially the alcohols, which was more than 2 folds higher in the inner liner (printing) than that in the inner liner (non printing), and the VOCs of the inner liner (printing) increased with the increase of the number of printing colors. Printing ink and auxiliary material had certain effects on heavy metals of the inner liner, and the Cr and Pb in the vacuum aluminum (transfer) inner liner were only about 50% and 10% of those in the vacuum aluminum (direct plating) inner liner. Conclusion Not only the base paper, but the printing ink and auxiliary material also had certain effects on the VOCs and heavy metals of the inner liner.
