Take by weighing calcium carbonate powder, adding water, to be mixed with mass percentage concentration be that 0.0016% calcium carbonate dissolves, and carries out grain size analysis, and calcium carbonate particle size distribution analysis result sees Fig. 1.
Visible by accompanying drawing 1; Paper grade (stock) calcium carbonate itself is not the particle of spheroidal; Its diameter is not represented the absolute diameter on the ordinary meaning; What its was represented is a distribution situation, promptly changes to the integral curve of a lower limit continuously from a higher limit, and the diameter here can only be the assembly average of all changes value.Grain diameter value is not unique, and it is with to measure used instrument and statistical method relevant.No matter using the particle size analyzer (laser or sedimentation) of which kind of principle, all can not go to measure all and connect the distance between 2 of the particle surfaces through center of gravity, is equivalent grain size so claim measured particle diameter.Equivalent grain size generally uses volume average particle size to provide numerical value with volume average particle size D (4,3) and surface area average grain diameter D (3,2) expression traditionally.
Provide the explanation of parameter in the granularity graph: the figure in the grain size analysis report is differential distribution map (being the frequency distribution map), but not cumulative distribution table; Volume average particle size D (4,3) and surface area average grain diameter D (3,2) represent the weighted average of particle diameter to volume (quality) and surface area respectively.
D (0.1) expression particle diameter accounts for 10% of cumulative volume less than the volume of the particle of d (0.1);
50% (being meso-position radius) that d (0.5) expression particle diameter respectively accounts for cumulative volume less than it with greater than its particle volume;
D (0.9) expression particle diameter accounts for 90% of cumulative volume less than the volume of the particle of d (0.9).
Span is represented the relative width and the degree of irregularity of size distribution.Specifically be expressed as:
Span=[d (0.9)-d (0.1)]/d (0.5);
Uniformity is measuring with respect to the absolute deviation of mean value.
Calcium carbonate granularity figure overall distribution is narrow, span little (1.037), peak value high (13.67), the big (2.26m of specific area
2/ g), maximum particle size is 8.71 μ m, and even particle size distribution is described.
Prepare the reconstituted tobacco paper substrate by embodiment 1 step; Wherein step (4) adds running water with the tobacco mixed slurry; Being mixed with solid content is the tobacco slurry suspension of 0.5 wt.%, is uniformly dispersed, and (concentration is 20g/L to wherein adding calcium carbonate aqueous solution under stirring at low speed; Agitating solution mixes it), making the carbonic acid of adding, calcareous to make its quality percentage composition final in mixed slurry be 50%.Stir 30s, add guar gum suspension, continue to stir 1min, copy sheet rapidly, other steps are with embodiment 1.Wherein the addition of guar gum prepares multiple reconstituted tobacco paper substrate (sheet paper base) from 0% being increased to 1.5% (in guar gum final quality percentage composition mixed slurry).The result is following to the sheet paper base measuring physical properties:
1. different guar gum consumptions are seen table 1 to the influence of paper substrate physical property
Table 1
Annotate: CaCO
3Consumption is 50%.
The consumption of guar gum is increased to 1.5% from 0%, assigns to see from the ash of sheet paper base, and the ash content of sheet paper base is increased to 16.67% from 4.14%, and the content of ashes of sheet paper base changes greatly, and content of ashes has increased by 12.53%.Explanation under experiment condition, the consumption of guar gum to calcium carbonate in sheet paper base to keep influential effect bigger.It can also be seen that from table 1 consumption of guar gum is at 0.5% o'clock, the tensile strength of sheet paper base is 1.19 kN/m, and tear index is 1.65 mNm
2/ g, bulk is 1.84 cm
3/ g, the ash content of sheet paper base has reached 15.21%; Continue to increase the consumption to 1.5% of guar gum, the tensile strength of sheet paper base is increased to 1.28 kN/m from 1.19 kN/m, and tear index has only increased by 0.09 mNm
2/ g, bulk is from 1.84 cm
3/ g drops to 1.77 cm
3/ g's 0.18 μ m/ (Pas), air permeability have risen, and the ash content of sheet paper base only increased by 1.46%, explain that 0.5% guar gum consumption is enough.Therefore, under experiment condition, the guar gum consumption increases, and little to the ash content contribution of sheet paper base, the intensity index of sheet paper base increases to some extent, and the bulk of sheet paper base and permeability rise along with the increase of ash content slightly to some extent.The applicability that from lot of experiment results, combines effect and cost calculation and actual production, the addition that sums up guar gum are 0.05%～0.5% o'clock of quality of tobacco slurry, can produce significant experiment effect.
2. different guar gum consumptions are to the influence of paper substrate permeance property
Wetability Max is meant that the reconstituted tobacoo paper substrate is reached the time after the highest by complete wetting and signal strength signal intensity, and it is along with liquid increases in the increase of the paper surface time of staying.Present embodiment is test liquid with water, and the Max value is big more, and the water repelling property of expression sheet paper base is good more.To be pattern reached the time of being experienced at 95% o'clock by liquid infiltration and signal strength signal intensity to characteristic value t95; It is with the aqueous solution as test liquid, this moment, the permeability of pattern only received the influence of paper pore structure, hole is more greatly or when open more; Aqueous solution infiltration is fast more; The t95 value is big more, and the surface porosity of expression sheet paper base is more little, and then anti-permeability performance is good more.
The surface texture of sheet paper base, permeance property and absorbent have very important influence to the follow-up painting process of sheet paper base.It is as shown in table 2 that the present invention sums up the permeance property that obtains the reconstituted tobacoo paper substrate of gained under the different guar gum consumption conditions.
Table 2 guar gum consumption is to the influence of sheet paper base permeance property
| Guar gum consumption/% | 0 | 0.1 | 0.2 | 0.25 | 0.28 | 0.3 | 0.50 | 0.6 | 0.75 | 1.00 | 1.50 |
| Max/s | 0.102 | 0.116 | 0.121 | 0.129 | 0.138 | 0.147 | 0.185 | 0.213 | 0.261 | 0.293 | 0.433 |
| Cobb30/g·m -2 | 26.7 | 26.0 | 25.4 | 25.2 | 24.8 | 24.5 | 23.9 | 23.5 | 23.1 | 20.9 | 12.7 |
| Cobb60/g·m -2 | 29.0 | 28.5 | 28.1 | 27.9 | 27.7 | 27.4 | 26.7 | 26.5 | 26.3 | 24.8 | 15.7 |
| t95/s | 0.097 | 0.253 | 0.362 | 0.449 | 0.473 | 0.497 | 0.541 | 0.82 | 1.018 | 1.048 | 1.482 |
The t95 value has characterized the surface pore structure of sheet paper base, and is visible by table 2, when the guar gum consumption is 0%; T95 value minimum (0.097 s) explains that the surface porosity of sheet paper base this moment is maximum, and the t95 value increases along with the increase of guar gum consumption gradually; Reduce gradually the surface pore of sheet paper base, when the guar gum consumption is 1.5%, and t95 value maximum (1.482 s); The surface porosity that sheet paper base this moment is described is minimum, this is because the guar gum consumption increases, and has promoted combining between the fiber and fiber in the paper; The calcium carbonate quantity of keeping in the sheet paper base and the amount of fiber fines increase; Calcium carbonate and fiber fines that the space on sheet paper base surface is kept cover, thereby have obtained the sheet paper base surface texture that relatively seals, be unfavorable for liquid from the sheet paper base surface seepage to inside.
Can find out that from table 2 wetability Max value and t95 value demonstrate close Changing Pattern, all are increase trend along with the increase of guar gum consumption.When the guar gum consumption is 0%, Max value minimum (0.102 s), the permeance property of expression sheet paper base is best; When the guar gum consumption is 1.5%, Max value maximum (0.433 s), the guar gum consumption increases, and guar gum has the effect of similar glue, and combining between fiber and the fiber become closely, and the permeance property of sheet paper base is the phase strain differential also.
The Cobb30 value and the Cobb60 value of sheet paper base are as shown in table 2 under the different guar gum consumptions.Cobb30 value and Cobb60 value demonstrate close Changing Pattern, all demonstrate reduction trend along with the increase of guar gum consumption.When the guar gum consumption was 0%, the water absorbing properties of sheet paper base was maximum, and Cobb30 value and Cobb60 value are respectively 26.7 g/m
2With 29.0 g/m
2When the guar gum consumption was 1.5%, the Cobb30 value and the Cobb60 value of sheet paper base dropped to 12.7g/m respectively
2With 15.7 g/m
2, the water absorbing properties of sheet paper base obviously descends.

| Ash content/% | 8.98 | 10.19 | 11.75 | 13.58 | 15.17 | 15.43 | 16.04 | 16.58 |
Visible by table 3, CaCO
3Addition increases to 50% from 10%, and the ash content of sheet paper base increases to 15.17% from 8.98%, and ascensional range reaches 6.19%, and CaCO is described
3Addition has bigger influence to the ash content of sheet paper base, thereby causes the physical property of sheet paper base also to change thereupon.CaCO
3Addition increases to 50% from 10%, and the tensile strength of sheet paper base drops to 1.18 kN/m from 1.45 kN/m, tear index 0.26 mNm that descended
2/ g, bulk is from 1.81 cm
3/ g rises to 1.91 cm
3/ g's 0.37 μ m/ (Pas), air permeability have risen.Therefore, CaCO
3Addition increases, and the intensity index of sheet paper base descends gradually, and the bulk and the air permeability of sheet paper base rise slightly.When the consumption of calcium carbonate when 50% increases to 70%, the ash content of sheet paper base is increased to 16.58% from 15.17%, has only increased by 1.41%, the amplitude of increase is very little; And the increase of calcium carbonate consumption, the tensile strength of sheet paper base, tensile index and tear index equal strength index constantly descend, and the bulk and the air permeability of sheet paper base rise slightly.Comprehensively above-mentioned, the calcium carbonate consumption is can obtain in 50% o'clock to keep effect preferably, and this moment, sheet paper base still can keep intensity index preferably.

Table 6 Kajaani FS300 fibre analysis
| Raw material | The wood-pulp board fiber | Making beating back wood pulp cellulose | Tobacco stalk fibre | Tobacco stalk fibre |
| Beating degree/ oSR | 13 | 33 | 16 | 23 |
| Number average length L n/mm | 0.53 | 0.38 | 0.33 | 0.30 |
| Weight average length Lw/mm | 2.67 | 2.35 | 0.88 | 0.77 |
| Two-fold weight average length Lww/mm | 1.82 | 1.37 | 1.79 | 1.41 |
| Fines (n) content/% | 58.03 | 60.21 | 45.65 | 47.30 |

| Fiber curl/% | 18.6 | 15.6 | 14.3 | 14.0 |
Visible by table 6, the fiber weight average length (Lw) of wood-pulp board is 2.67mm, and after making beating, beating degree is 33
oSR, the weight average length of wood pulp cellulose is 2.35 mm, and the weight average length of fiber has shortened 0.32mm, wood pulp cellulose is described in pulping process, and fibre length has certain loss.But compare with tobacco stalk fibre, the fiber weight average length of tobacco stalk fibre is that (beating degree is 16 to 0.88 mm
oSR) and 0.77 mm (beating degree is 23
oSR), the wood pulp cellulose length after this explanation making beating still exceeds much than tobacco stalk fibre length.
2. add the influence of wood pulp to reconstituted tobacco paper substrate physical property
Prepare the reconstituted tobacco paper substrate by embodiment 1 step; Wherein step (4) adds running water with the tobacco mixed slurry; Being mixed with solid content is the tobacco slurry suspension of 0.5 wt.%, is uniformly dispersed, and under stirring at low speed, accounts for the tobacco slurry mass percent and is respectively 2%, 3%, 6%, 9%, 12%, 15% and 20% wood pulp cellulose to wherein adding to add respectively; Other steps prepare the reconstituted tobacco paper substrate with embodiment 1.
(1) different wood pulp consumptions to the sheet paper base physical property to influence testing result as shown in table 7.
The different wood pulp consumptions of table 7 are to the influence of paper substrate physical property
Visible by table 7, owing to having added intensity and length wood pulp cellulose preferably, the tensile index and the tear index of making beating back wood pulp cellulose have reached 37.40 Nm/g and 9.09mNm
2/ g so the tensile index of sheet paper base and tear index all are ascendant trend faster along with the increase of wood pulp consumption, sees shown in the accompanying drawing 6.The tensile index and the tear index that do not add the sheet paper base of wood pulp are 11.65 Nm/g and 1.14 mNm
2/ g, when the wood pulp addition was 3%, the tensile index of sheet paper base and tear index rose to 12.22 Nm/g and 1.42 mNm
2/ g, the strength character of sheet paper base increases slightly; When the addition of wood pulp was 6%, the tensile index of sheet paper base and tear index rose to 14.29 Nm/g and 1.90 mNm
2/ g, the strength character of sheet paper base be improved significantly; When the wood pulp addition was 15%, the tensile index of sheet paper base and tear index rose to 19.76 Nm/g and 2.85 mNm
2/ g, the strength character of sheet paper base is significantly improved.
Because the rugosity of wood-pulp board fiber is 0.324 mg/m (table 6), the rugosity value of fiber is very high, and visible by table 6, the wood-pulp board fiber becomes the bulk of paper also very high, is 3.05 cm
3/ g; The rugosity of wood pulp cellulose and bulk all descend to some extent after the making beating, are respectively 0.112 mg/m and 2.15 cm
3/ g, when this explanation making beating let the fiber wire-dividing broom purification, the rugosity of fiber also descended simultaneously.The bulk of not adding the sheet paper base of wood pulp is 2.36 cm
3/ g, the bulk of wood pulp cellulose exceeds 0.21 cm than pulling an oar afterwards
3/ g.Can find out from table 7; The addition of wood pulp is increased to 20% from 2%; The bulk of sheet paper base does not change basically, and main cause is that making beating back wood pulp cellulose becomes the bulk of paper lower slightly than the bulk of sheet paper base, so it is afterwards little to the influence of sheet paper base to cause adding wood pulp.
From table 7, the air permeability of making beating back wood pulp is 11.80 μ m/Pas, and the air permeability that does not add the sheet paper base of wood pulp cellulose is 2.34 μ m/Pas, this shows, the air permeability of wood pulp exceeds 9.46 μ m/Pas than the air permeability of sheet paper base.When the addition of wood pulp in sheet paper base is 3%; The air permeability of sheet paper base is 2.56 μ m/Pas; The air permeability of sheet paper base increases slightly to some extent, and when the addition of wood pulp in sheet paper base was 6%, the air permeability of sheet paper base was 3.37 μ m/Pas; The air permeability of sheet paper base has increased by 44.02%, and the air permeability of sheet paper base significantly increases.
(2) different wood pulp consumptions are to the testing result that influences of sheet paper base permeance property
Table 8 wood pulp consumption is to the influence of sheet paper base permeance property
| Wood pulp consumption/% | Making beating back |
0 | 2 | 3 | 6 | 9 | 12 | 15 | 20 |
| Max/s | 0.041 | 0.197 | 0.196 | 0.193 | 0.169 | 0.141 | 0.129 | 0.057 | 0.052 |
| Cobb30/g·m -2 | 27.9 | 26.7 | 26.7 | 26.7 | 26.8 | 27.3 | 27.3 | 27.5 | 28.0 |
| Cobb60/g·m -2 | 29.6 | 28.4 | 28.6 | 28.9 | 29.0 | 29.1 | 29.2 | 29.5 | 29.8 |
| t95/s | 0.012 | 0.960 | 0.730 | 0.619 | 0.602 | 0.520 | 0.431 | 0.412 | 0.392 |
Characteristic value t95 characterizes the porosity on sheet paper base surface, can be found out by table 8, and the t95 value of making beating back wood pulp is very little; Be 0.012 s; Explain that making beating back wood pulp cellulose has elasticity preferably, become the porosity on paper surface very high, be very beneficial for liquid and infiltrate into page inside.Do not add the sheet paper base t95 value maximum (0.960 s) of wood pulp, when the wood pulp addition was 3%, the t95 value of sheet paper base was 0.619 s; When the addition of wood pulp was 15%, the t95 value of sheet paper base was 0.412 s, along with the increase of wood pulp addition; The t95 value of sheet paper base descends gradually; Explain that wood pulp adds in the sheet paper base, help the sheet paper base surface and obtain open more surface texture that it is inner from the sheet paper base surface seepage to sheet paper base to help liquid.
Wetability Max is meant that the reconstituted tobacoo paper substrate is reached the time after the highest by complete wetting and signal strength signal intensity, and it is along with liquid increases in the increase of the paper surface time of staying.The Max value of making beating back wood pulp is very little, is 0.041 s, explains that wood pulp has increased in the adhesion between fiber and the fiber after the making beating, still is very good but wood pulp cellulose becomes the permeance property of paper.Can find out that from table 8 wetability Max value and t95 value demonstrate close Changing Pattern, all are increase trend along with the increase of wood pulp addition.Do not add the sheet paper base Max value maximum (0.197 s) of wood pulp, the permeance property of expression sheet paper base is the poorest; When the wood pulp addition was 6%, the Max value dropped to 0.169 s, when the wood pulp addition increases to 15%; Max value minimum (0.057 s); The wood pulp addition increases, and helps forming more loose pore structure between fiber and the fiber, and the permeance property of sheet paper base is corresponding to improve.
The Cobb30 value and the Cobb60 value of sheet paper base are as shown in table 8 under the different wood pulp addition conditions.The Cobb30 value and the Cobb60 value of making beating back wood pulp are the highest, are respectively 27.9 g/m
2With 29.6 g/m
2From table 8, Cobb30 value and Cobb60 value demonstrate close Changing Pattern, all demonstrate increase trend along with the increase of wood pulp addition.When the wood pulp addition was 0, the water absorbing properties of sheet paper base was minimum, and Cobb30 value and Cobb60 value are respectively 26.7 g/m
2With 28.4 g/m
2When the wood pulp addition was 15%, the Cobb30 value and the Cobb60 value of sheet paper base rose to 27.5 g/m respectively
2With 29.5 g/m
2, under experiment condition, the interpolation of wood pulp increases the absorbent of sheet paper base slightly to some extent, but changes little.
Comprehensively above-mentioned; The addition of wood pulp in sheet paper base increases, because wood pulp cellulose has elasticity and intensity preferably, the hole on sheet paper base surface increased gradually; Structure between sheet paper base internal fiber and the fiber becomes loose; Help the surface pore infiltration of liquid from sheet paper base, permeance property increases, and the whole absorbent of sheet paper base rises along with the increase of wood pulp addition to some extent.
(3) add the scanning electron microscope analysis of wood pulp to the reconstituted tobacoo paper substrate
That accompanying drawing 7 ~ 13 shows is the surperficial SEM figure of wood pulp and sheet paper base.Wherein, a1 is that wood-pulp board fiber surface (500 *), a2 are that wood-pulp board fiber, (100 *), b1 are that 3% wood pulp cellulose sheet paper base (500 *), c2 are that 3% wood pulp cellulose sheet paper base (100 *), d 1 are that 6% wood pulp cellulose sheet paper base (500 *), d2 are that 6% wood pulp cellulose sheet paper base (100 *), e1 are that 9% wood pulp cellulose sheet paper base (500 *), e2 are that 9% wood pulp cellulose sheet paper base (100 *), f1 are that 12% wood pulp cellulose sheet paper base (500 *), f2 are that 12% wood pulp cellulose sheet paper base (100 *), g1 are that 15% wood pulp cellulose sheet paper base (500 *), g2 are the surperficial SEM figure of 15% wood pulp cellulose sheet paper base (100 *) for making beating back wood-pulp board fiber (500 *), b2 for making beating back wood-pulp board fiber (100 *), c1.From accompanying drawing 7 ~ 13, the wood pulp cellulose smooth surface of making beating not, fiber is stiff, the adhesion between fiber and the fiber a little less than, become paper structure more loose, intensity is lower, air permeability good (accompanying drawing a1 and figure a2); Tangible wire-dividing broom purification appears in the wood pulp cellulose after the making beating, in the pulping process, is accompanied by continuing of shear action and conquassation effect; The fiber finer cell is by conquassation, and fiber has had the cut-out of considerable part, and then fibrillating; (accompanying drawing b1 and figure b2) strengthened in fibre swelling, the wire-dividing broom purification effect of fiber, improved the binding ability between fiber and the fiber; Thereby tensile index and tear index increase greatly, and can also keep permeability (table 2) preferably.The surface porosity factor of wood pulp of not pulling an oar is maximum, though the porosity of wood pulp diminishes to some extent after the making beating, porosity is still very high.The addition of wood pulp increases gradually in the sheet paper base, when the sheet paper base physical strength increases, has improved the surface property of sheet paper base effectively, and the porosity on sheet paper base surface is along with the addition of wood pulp increases and obviously increases.
Do not pull an oar wood pulp cellulose because more stiff, and adhesion is more weak, and bulk is high, and its cross section fiber is more open, and internal structure is loose (accompanying drawing 14a) relatively.Wood pulp cellulose wire-dividing broom purification after the making beating, fiber surface is owing to have adhesion preferably, and SEM schemes (accompanying drawing 14b) from its cross section, and the tightness of fiber increases, and becomes the bulk of paper to descend more.Add making beating wood pulp afterwards in the sheet paper base,, help improving the internal structure of sheet paper base because wood pulp cellulose has toughness and elasticity preferably.From accompanying drawing 14 ~ 19, the addition of wood pulp increases in the sheet paper base, and the inner structure of sheet paper base becomes loose, and the hole of appearance increases, thereby the air permeability of sheet paper base is increased.
(4) add the influence of wood pulp to reconstituted tobacoo paper substrate flue gas

Table 9 has shown the flue gas analysis result who adds sheet paper base behind the wood pulp.Along with the increase of wood pulp addition, the air permeability of sheet paper base increases, thereby improves the combustibility of sheet paper base, and the interpolation of wood pulp reduced the consumption of offal and offal in the Cigarette, and the tar content of sheet paper base is also therefore reduction.Visible by table 9; The sheet paper base tar content and the CO amount of not adding wood pulp are respectively 9.7 mg and 20.70 mg; When the wood pulp addition was 6%, the tar content of sheet paper base and CO amount were 8.0 mg and 19.7 mg, have descended 17.53% and 4.83% respectively; TPM is propped up by 11.83 mg/ and drops to 10.25 mg/ and prop up, and puff number also drops to 4.8 by 5.7.Continue to increase the wood pulp addition, the tar content of sheet paper base and CO amount continue on a declining curve.This shows, add wood pulp in sheet paper base, reduced tar content and the CO amount in the sheet paper base, simultaneously, TPM amount and puff number also have decline in various degree.
Comprehensively above-mentioned; The experimental result of adding wood pulp in the sheet paper base shows, the addition of wood pulp increases to 15% from 3%, because wood pulp cellulose has elasticity and intensity preferably; The tensile index of sheet paper base, tear index, air permeability be improved significantly; The hole on sheet paper base surface increases gradually, and the structure between sheet paper base internal fiber and the fiber becomes loose, helps the surface pore infiltration of liquid from sheet paper base; Permeance property increases, and the whole absorbent of sheet paper base rises along with the increase of wood pulp addition to some extent.The tar content of sheet paper base and CO amount all has decline in various degree simultaneously.Because the addition of wood pulp increases, the sensory evaluating smoking of reconstituted tobacoo is brought counter productive, so the addition of wood pulp in sheet paper base is just few as far as possible.From above-mentioned experimental result; The addition of wood pulp is 6% o'clock; The physical property of sheet paper base and permeance property be improved significantly; And indexs such as the tar content of sheet paper base, CO amount, TPM have realized decline to a certain degree, take all factors into consideration, so the addition of selected wood pulp is 6%.

Along with CaCO
3The increase of consumption, the air permeability of sheet paper base increases, thereby improves the combustibility of sheet paper base, and the increase of calcium carbonate consumption reduced offal and the shared ratio of offal in the Cigarette, and the tar content of sheet paper base is therefore reduction also.Table 12 is a wood pulp consumption 6%, adds Different Ca CO
3The flue gas analysis result of sheet paper base behind the consumption.Visible by table 12, do not add and fill out CaCO
3Sheet paper base tar content and CO amount be respectively 8.0 mg and 19.7 mg, work as CaCO
3Consumption is 50% o'clock, and the tar content of sheet paper base and CO amount is 6.5 mg and 16.3 mg, has descended 18.75% and 17.25% respectively, and TPM is propped up by 10.25 mg/ and drops to 8.25 mg/ and prop up, and puff number also drops to 4.5 by 4.8.Continue to increase CaCO
3Consumption, the tar content of sheet paper base and CO amount continue on a declining curve.This shows, add CaCO
3In sheet paper base, reduced tar content and the CO amount in the sheet paper base, simultaneously, TPM amount and puff number also have decline in various degree.
The experimental result of adding wood pulp in the sheet paper base shows; The addition of wood pulp increases to 15% from 3%; Because wood pulp cellulose has elasticity and intensity preferably, the tensile index of sheet paper base, tear index, air permeability be improved significantly, the hole on sheet paper base surface increases gradually; Structure between sheet paper base internal fiber and the fiber becomes loose; Help the surface pore infiltration of liquid from sheet paper base, permeance property increases, and the whole absorbent of sheet paper base rises along with the increase of wood pulp addition to some extent.The interpolation of wood pulp makes the tar content of sheet paper base and CO amount that decline in various degree all arranged.Because the addition of wood pulp increases, the sensory evaluating smoking of reconstituted tobacoo is brought counter productive, so the interpolation of wood pulp in sheet paper base should be more the least possible.Through taking all factors into consideration and constantly experiment and analysis; The present invention sums up, and the addition of wood pulp is 6% o'clock, the physical property of sheet paper base and permeance property be improved significantly; And the tar content of sheet paper base and CO amount also have decline to a certain degree, so the addition of selected wood pulp is 6%.
Further, the present invention studies summary, when the wood pulp addition is 6%, adds in the sheet paper base and fills out CaCO
3Increase to 70% from 15%, the physical strength of sheet paper base descends to some extent, and the permeance property and the absorbent of sheet paper base improve.Do not add and fill out CaCO
3Sheet paper base tar content and CO amount be respectively 8.0 mg and 19.7 mg, work as CaCO
3Consumption is 50% o'clock, and the tar content of sheet paper base and CO amount is 6.5 mg and 16.3 mg, has descended 18.75% and 17.25% respectively, and TPM is propped up by 10.25 mg/ and drops to 8.25 mg/ and prop up, and puff number also drops to 4.5 by 4.8.Continue to increase CaCO
3Consumption, the tar content of sheet paper base and CO amount continue on a declining curve, if but the consumption of dosing calcium carbonate surpasses 50%, and the wing is not obvious in the ash content increase of paper substrate, and it is little to the sheet paper base effect therefore to increase the calcium carbonate consumption again.The calcium carbonate consumption surpasses after 50%, and the physical strength of paper substrate descends very fast, is unfavorable for that the production of paper substrate is manufactured paper with pulp.So, confirm when the wood pulp addition is 6%, adds in the sheet paper base and fill out CaCO
3Amount is 50%.
The optimum addition of embodiment 7 calcium carbonate, wood pulp cellulose and guar gum
The calcium carbonate amount of filling account for tobacco material slurry quality 50%, the wood pulp cellulose addition account for tobacco material slurry quality 6%, guar gum accounts for 0.25% o'clock of tobacco material slurry quality, the performance index of the paper substrate of the reconstituted tobacco for preparing is following:
