HS-GC/MS法测定烟标中VOCs及影响因素分析

Determination of VOCs in Cigarette Label by HS-GC/MS and Analysis of Influencing Factors

通过分析烟标礼盒生产工艺,利用顶空-气质联用法对不同阶段的原材料、半成品和成品中VOCs残留量进行测定,对影响成品烟标礼盒VOCs残留量的主要因素进行了分析,同时探究了降低成品烟标礼盒VOCs的有效方法。结果表明,在常规生产过程中,影响成品烟标礼盒的主要因素为胶粘剂的使用、丝网目数、皮壳板原辅料以及成品烟标礼盒生产完成后的处理方式。成品烟标礼盒生产完成后摆放2天,溶剂杂质和溶剂残留的含量能得到有效降低;设置合适的抽湿时间可以使成品烟标礼盒中VOCs残留量降低到出库标准。

By analyzing the production process of cigarette label gift boxes,using Headspace-Gas Chromatography/Mass Spectrometry to determine the VOCs residues in raw materials,semi-finished products and finished products at different stages,the main factors affecting the VOCs residues of finished cigarette label gift boxes are analyzed.And then,the effective method to reduce the VOCs of the finished cigarette label gift box is explored.The results show that the main factors affecting the finished cigarette label gift box are the use of adhesives,the number of screen meshes,the raw materials of the shell board and the processing methods after the production of the finished cigarette label gift box.After being placed for two days,the solvent impurities and residual solvent content in the finished cigarette label gift box can be effectively reduced.Setting a proper dehumidification time can reduce the residual amount of VOCs in the finished cigarette label gift box to the standard of the warehouse.
