Abstract
Description
technical field
[0001] The invention relates to a method for measuring the concentration distribution pattern of HCN intercepted by a filter tip, and belongs to the field of cigarette technology research. Background technique
[0002] Cigarette filters can effectively intercept tar and other harmful components in mainstream smoke. When developing low-tar cigarette products, improving the smoke retention efficiency of filters is often the first choice of researchers. With the continuous expansion of the market for low-tar and ultra-low-tar cigarette products, more and more researches have been conducted on the interception efficiency, interception law and interception mechanism of various components in mainstream smoke by filters of various materials and specifications. Pay attention to. Keith first studied the mechanism of smoke filtering by filters, and the research results showed that there are three main ways of filtering smoke particles in filters: inertial collision, ...
