(2) second and third section defibrination is on the impact of tobacco stalk fibre
After the selected A mill slurry of first paragraph defibrination gap is 0.4mm, change abrasive disc, carry out the experiment of second segment defibrination.In order to determine the gap of second segment defibrination, in conjunction with the performance of fiber behind offal characteristic and the first paragraph defibrination, the utility model adopts different dish and grinding clearances to carry out the experimental study analysis.Take different grinding clearances as example, adopted respectively the grinding clearance of 0.30mm, 0.25mm and 0.20mm to carry out lab scale experiment gained offal slurry form (operation as an example of the J dish example), when grinding clearance was 0.3mm and 0.25mm, gained offal slurry was still more coarse, stiff; When grinding clearance was 0.20mm, the offal that obtains slurry was relatively finer and smoother, soft, and fiber had certain wire-dividing broom purification ability, was 0.20mm so select the gap of second segment defibrination.The experimental result of second segment defibrination is as shown in table 3.
Table 3 offal second segment defibrination experimental result (J dish)
The gap of selected second segment defibrination is 0.2mm, selects different mills to carry out the experiment of second segment defibrination under the gap is the condition of 0.2mm respectively again, does not change abrasive disc after the second segment defibrination, carries out the 3rd section defibrination.Experimental result is as shown in table 4.
The weight in wet base of fiber is the secondary indication average fiber length, and more the fubril average length is less for weight in wet base, and the larger average fiber length of weight in wet base is longer.Beating degree is reflection making beating degree, weigh the index (drainability) of deckering complexity, concentrated expression fiber be cut off, swollen, wire-dividing broom purification, fibrillating degree.From table 4, second segment defibrination D dish and K dish are all obtained preferably refining effect, and the beating degree of tobacco stalk fibre is respectively 17
0SR and 26
0SR, weight in wet base is 4.9g and 5.1g; Second segment adopts J mill slurry, and the beating degree of tobacco stalk fibre is 25
0SR, weight in wet base is 2.3g, the average fiber length that J dish gained offal slurry is described is less than the offal slurry of two dishes of D, K gained.
The 3rd section unified 0.15mm grinding clearance that adopts carries out defibrination, D, J, K dish carry out the 3rd section defibrination experimental result and are shown in Table 4, and tobacco stalk fibre is after the 3rd section defibrination, and the weight in wet base suppression ratio of fiber is very fast, offal is described after the 3rd section defibrination, the average fiber length suppression ratio is very fast.After the 3rd section defibrination, the beating degree of D dish gained offal slurry is minimum, is 28
0SR, the weight in wet base of fiber is 2.0g; The weight in wet base of J dish gained offal slurry is minimum, is 0.9g, illustrates that the 3rd section is adopted the J dish to carry out defibrination, and is larger to the cut-out of tobacco stalk fibre; The weight in wet base of K dish gained offal slurry is maximum, is 3.1g.
Second and third section of table 4 offal defibrination experimental result
* in the table 4, second segment grinding clearance: 0.2mm; The 3rd section grinding clearance: 0.15mm; The second segment defibrination is identical abrasive disc model with the 3rd section defibrination employing.
Second and third section of table 5 offal defibrination experimental result (slurry behind the sieve)
By analysis contrast, determine to adopt sieve plate sieve seam offal is starched to be screened for the ZQS5 type pulp screen of 0.3mm (being the dull and stereotyped vertical pulp screen of Φ 300mm) connects the slurry technical scheme to the tobacco stalk fibre after second segment and the 3rd section defibrination, selected offal slurry adopts 150 purpose polyester mesh bags to connect slurry, and experimental result is as shown in table 5.From table 5, D, J, K mill slurry are starched (shown in the table 4) with the offal of not screening and are compared, and after the screening, the beating degree of offal slurry has in various degree decline, and weight in wet base increases apparent in view.Main cause is that screening adopts 150 purpose polyester mesh bags to connect slurry, in the screening process owing to adopt a large amount of dilution water flushings, cause running off larger less than 150 purpose components, can find out from the situation of screened yield and thick slag rate, the large percentage that the component that runs off accounts for, the second segment defibrination is about 20%～25%, and the component that the component of the 3rd section defibrination K dish loss accounts for the loss of 12%, D, J dish accounts for 21%～25%.
Adopt fiber quality analyzer to measure to the slurry of second and third section offal after the screening, measure the length of offal slurry, content and the fibre coarseness of fiber fines, test result is shown in Table 6.From the result of fibre analysis, the fibre length of the offal of second segment defibrination is longer, and the fibre length of D dish gained offal slurry is maximum, secondly is the K dish, is the J dish afterwards, and fibre length is all influential to the various strength characters of paper, but influence degree is different.The fibre length of offal slurry is than the to some extent decline of second segment defibrination after the 3rd section defibrination, but the fibre length that remains D dish gained offal slurry is maximum, secondly is the K dish, is the J dish afterwards.Therefore, second segment and the 3rd section employing D mill slurry, the fiber quality of gained offal slurry is better.
Table 6Kajaani FS300 fibre analysis result
Except fibre length, rugosity, tiny constituent content also is to estimate important indicator of fibrous raw material quality good or not.The high-quality fibrous raw material all contains the non-fibrocyte of small amount usually, because non-fibrocyte intensity is little, form is short and small, and geometry is irregular, and the power that interweaves is poor, and too high levels can cause that paper pulp yield descends, the impact washing.Drainage difficulty in paper-making process, l Water Paper page or leaf intensity difference causes the roll banding broken end, impact is produced, and finally causes paper strength to reduce.The second segment defibrination, the fines content of D, J, K dish gained offal slurry is more or less the same; The 3rd section defibrination, the fines content of K dish gained offal slurry is maximum, is that 35.77%, J dish gained offal slurry fines content is minimum, is 21.96%.Accompanying drawing 9～14 is the fibre-diagram of different abrasive disc models, different defibrination hop count and grinding clearance.
(3) offal slurry physical property
Adopt the PFI mill to pull an oar to the slurry of the second segment offal after the screening, the control beating degree is 20～30
0Between the SR, the 3rd section offal slurry is not then pulled an oar, and then experimental result carries out handsheet shown in table 3～6, detect physical property, and experimental result is as shown in table 7.
