- the cylindrical hollow filter rod contains a layer of separator, the separator is 6mm away from the end of the vinegar filter rod, the thickness of the hollow core cylinder is 0.8mm, the thickness of the separator is 1mm, and there are 6 through holes and the center of the through hole
- the positions are randomly distributed within a range of 0 to 1.5 mm from the center of the partition.
- the diameter of the through holes is 0.4 mm, which is denoted as F2 #.
- a cylindrical hollow tube type acetic fiber composite filter rod of the same length of 30 mm and a circumference of 16.8 mm is used without a partition.
- the composite structure is a 7 mm vinegar fiber filter rod + 23 mm empty tube filter rod, and the vinegar fiber filter rod is near the lip end. , Denoted as B0 #.
- the above 8 kinds of filter rods are respectively connected with cigarettes of the same process formula to form a heated, non-combustion thin new cigarette with a length of 72 mm and a circumference of 17.1 mm.
- the cigarettes are numbered in accordance with the number of the filter rods.
- the same thin new type cigarettes are heated, the highest heating temperature is 230-280 ° C, the cigarette is smoked according to the ISO standard method, and the maximum smoke temperature and smoke results of the outer lip of the filter are shown in Table 4:
- B1 #, B2 #, B3 #, and B4 # filter rods are applied to a new type of heated non-combustion cigarette with a circumference of 17.1mm.
- the highest smoke on the outer lip of the filter The temperature of the gas is greatly reduced, and the tar and nicotine in the flue gas are greatly increased.
- the application of B5 # and B6 # filter rods is similar to that of the vinegar fiber empty tube composite filter rod B0 #.
- the maximum temperature of the smoke at the outer edge of the filter is also significantly reduced, and the differences between tar and nicotine in the smoke are small.
- the diameter of the through hole is too small.
- the maximum temperature of the smoke at the lip of the outer edge of the filter is low, the amount of smoke is too small and the tar and nicotine in the smoke are too small. If it is too low, the suction resistance is large and the feeling of evacuation is obvious.
- the side of the vinegar fiber filter rod section near the heating zone of the smoking article was affected by the high-temperature smoke and caused the problem of melting and forming agglomerates, which led to the smoke from the third mouth, Even at the beginning of the second mouth, the suction resistance increased and the amount of smoke decreased significantly.
- the B5 # and B6 # composite filter rods can effectively reduce the temperature of the flue gas, and there is no obvious adverse phenomenon that the vinegar fiber filter rod section is melted into agglomerates.
- the cooling filter rod of the invention reduces the maximum smoke temperature at the lip of the outer edge of the filter while reducing the adsorption of cigarette smoke. Effectively reduce the retention and adsorption of cigarette filter rods on the heating and non-combustion of new type cigarette smoke, reduce the taste temperature of cigarette smoke, improve the sensory quality of cigarettes, and increase consumer satisfaction.
