Study on Resistance Characteristic of Groove Filter Rod

Abstract

In order to study the influence of groove on the resistance of filter rod, 6 different sizes (10+20,15+15,20+10), two different groove profiles (inner and outer grooves) were tested and analyzed. Results show that: (1) groove distribution of filter rod draw resistance has obvious effect, under the same conditions, inner grooved filter rod draw resistance greater than outer grooved filter rod draw resistance. The groove length is longer, the distribution of the trench suction on the impact resistance is greater: 20-10 inner and outer groove suction resistance difference >15+15 inner and outer groove suction resistance difference >10+20 inner and outer groove suction resistance difference. Groove length and draw resistance to reduce the proportion of a quadratic function relation. Grooved filter rod with increasing the length of the groove, the difference of suction rod resistance and light resistance increased.
