Preparation and application of filter rod components for reducing tar and harm in cigarette
A new type of cigarette filter rod component was prepared using injection molding mechanism which used thermoplastic elastomer material with added graphene nanomolecules as the substrate.The filter rod component was ternary composite with vinegar fiber filter rod and rolled into a composite filter rod cigarette sample.The effects of the new filter rod component on the main physical indicators of cigarettes,conventional components in mainstream smoke,and seven harmful components were studied.The results showed that graphene had a significant adsorption effect on phenol and benzo[a]pyrene,with little impact on other components;Compared with the same specifications of vinegar fiber filter rod cigarettes,the increase in suction resistance of the composite filter rod ciga-rette sample was 12.33%,and the increase in filter nozzle ventilation rate and total ventilation rate were 10.17%and 10.22%,respectively;The release of conventional components and seven harmful components in the main-stream smoke of composite filter rod cigarette samples had been reduced,with nicotine decreased by about 36%and tar decreased by about 34%.The reduction effect of harmful components carbon monoxide,hydrogen cyanide,cro-tonaldehyde,and nitrosamine was more significant,with reductions of about 53%,50%,62%,and 78%,respectively.The hazard index of composite filter rod cigarette samples had decreased on average from 10.28 to 4.95,the designed graphene shaped filter rod component had a significant effect on reducing tar and harm.
