磷酸钾添加量对卷烟纸及卷烟烟气的影响研究

Research of adding dosage of potassium phosphate on cigarette paper performance and cigarette smoke

在卷烟纸上添加磷酸钾燃烧助剂,采用热重分析和卷烟常规烟气分析方法,研究了磷酸钾添加量对卷烟纸及卷烟烟气的影响。结果表明:(1)增加磷酸钾添加量可以降低卷烟纸初始热解温度和热解活化能;(2)卷烟纸的磷酸钾含量为1%～2.5%时,卷烟每口烟气的CO量较低;(3)以卷烟每口烟气的焦油量作为评价标准,增加磷酸钾添加量,能够导致卷烟每口烟气焦油物质递送量的增加。

The effect of adding dosage of potassium phosphate on cigarette paper performance and cigarette smoke was studied with Thermo gravimetric analysis and routine smoke analysis. Results show that： （1） Increasing the additives dosage may reduce the initial thermal decomposition temperature and pyrolysis activation energy of cigarette paper; （2） Carbon monoxide content in cigarette mainstream smoke per puff is lower when the adding dosage of potassium phosphate is 1% -2.5%; （3） Increasing adding dosage of potassium phosphate on cigarette paper can lead to the increase of tar material per puff：
