| Abstract:This study analyzed the characteristics of tobacco raw materials， investigated suitable detection methods for the screening distribution of pulp slurry， examined the screening distribution of the pulp slurry at different sampling points along the production line after beating with different power， and explored the relationships between screening distribution indicators of pulp slurry and the key physical properties of handsheets. The results indicated that tobacco stems and tobacco dust contained fewer fibrous cells， with shorter fibers and more non-fibrous cells， suggesting that the mixed tobacco pulp did not consist of a single fiber morphology. The suitable detection method for screening distribution of pulp slurry was as follows： using sieve plates with aperture of 1 180， 830， 600， 300， and 75 μm， with a screening time of 10~20 minutes and a pulp sampling amount of 10~16 grams. Centrifugal dewatering could be used instead of drying to process the pulp fractions. The proportion of the pulp particle size ［1 180， +∞）μm exhibited a pattern of “Sampling Point 1 > Sampling Point 2 > Sampling Point 3，” while the proportion of the pulp particle size ［75， 300）μm showed a pattern of "Sampling Point 3 > Sampling Point 2 > Sampling Point 1.“ As the mill power decreased， the proportions of the pulp particle sizes ［1 180， +∞）μm and ［830， 1 180）μm increased. When the proportions of the pulp particle size ［1 180， +∞）μm at the first sampling point was 36.1%， the bulkiness of the handsheets increased by 14.2%， the liquid absorption height increased by 27.6%， and the tensile index decreased by 35.6%. |
