多聚磷酸铵对造纸法再造烟叶热解燃烧特性和感官质量的影响

Effects of Ammonium Polyphosphate on Pyrolysis-Combustion Characteristics and Sensory Quality of Paper-making Process Reconstituted Tobacco Sheet

摘要

摘要: 为了提高造纸法再造烟叶(RTS)的综合品质,探讨了多聚磷酸铵(APP)对造纸法再造烟叶热解燃烧特性和感官质量的影响。结果表明:①含有APP的造纸法再造烟叶(ARTS)和RTS均由5个热降解阶段组成。APP的添加并没有改变RTS的热降解过程,但明显降低了RTS在第2(200~280℃)、第3(280~370℃)和第4(370~670℃)热降解阶段的热失重速率。②RTS和ARTS热解过程中所释放的热解气体主要由H₂O,CO₂,CO,NH₃,羰基类,醇类和烷烃类化合物等组成。③微燃烧量热和锥型量热测试结果显示,ARTS的易燃性和可燃性均较RTS有所降低。④ARTS在香气质、浓度、刺激性、杂气和余味方面均较RTS有所改善,特别是在减轻刺激性和杂气方面,APP作用明显。

Abstract: In order to improve the quality of paper-making process reconstituted tobacco sheet (RTS), the effects of ammonium polyphosphate (APP) on the pyrolysis-combustion characteristics and sensory quality of RTS were investigated. The results showed that:1) The thermal degradation of both RTS and ARTS (APP-containing RTS) consisted of five stages. The application of APP did not change thermal degradation process, but obviously lowered the weight loss rate of RTS at the second (200-280℃), third (280-370℃) and fourth (370-670℃) thermal degradation stages. 2) The main gases released during the pyrolysis of RTS and ARTS were H₂O, CO₂, CO, NH₃, carbonyl compounds, alcohols, and alkanes. 3) The test results of micro-combustion calorimeter and cone calorimeter indicated that the flammability and combustibility of RTS were retarded somewhat by APP addition. 4) ARTS was superior to RTS in terms of aroma quality, concentration, irritation, offensive odor and aftertaste; and especially obvious in irritation and offensive odor In order to improve the quality of paper-making process reconstituted tobacco sheet (RTS), the effects of ammonium polyphosphate (APP) on the pyrolysis-combustion characteristics and sensory quality of RTS were investigated.
