Definitions
- the present invention relates to a process for the treatment of grass or hay for use as a substitute pulp, preferably in the paper industry.
- Processes for processing hay or grass for use in the paper industry are known.
- grass is used as a filler for papermaking.
- the grass is dried and comminuted to the extent that it can not contribute significantly to the strength in sheet formation, but as a cost effective organic filler both the surface properties and the opacity, i. the light-tightness of the paper sheet, positively influenced.
- the pug mill has at least one, preferably three, pug mill rolls, which continuously ground the pulp against a die, in particular a punch die.
- different matrices or screens are used in the different grinding units, with which also the fiber length
- the present invention also particularly includes the use of the corresponding pulp for the production of paper, board and / or board.
- the paper has a high tensile strength, so must not fall below a certain fiber length in order to exploit the strength potential of the pulp as well as possible.
- Different properties of grass or hay fiber can be achieved by appropriate process steps.
- Grass is a commodity that is available in large quantities and, above all, regionally. Grass grows quickly and can therefore be harvested in Central Europe in two to five cuts per year.
- Fiber must also have enough short fibers to achieve the desired pulp distribution and homogeneity in the paper.
- volume is replaced by a
- the tear strength is of the fiber length or the
- the fiber length (mm) is achieved by cutting in the corresponding mill.
- bonding active surface of the fibers are significantly increased. This is done essentially by the "exposure" of the educationally active fibers from the outer region of the fiber composite.
- Fiber is achieved by air classification with subsequent sieving. O The printability is especially the paper surface
- FIG. 2 the representation from FIG. 1 is the component of FIG.
- Starting raw material i. to the grass or hay, complements.
- a residual moisture content of not more than 15% and which has a harvest usual cut length which is, for example, between 0.1 mm and 500 mm.
- This grass or hay as described above, is fed to the process of processing grass or hay for the papermaking process.
- Heath fibers per hour is aligned.
- the fiber length is determined.
- Feeding for filling for example
- hay was used, which was delivered in the form of two bundled hay bales.
- This starting material contained long-fiber hay, ie with a fiber length of 50 to 80 mm, with dried hay fibers, a crude product moisture content of 9.3% and a bulk density of 0.07 kg / dm 3 .
- the flow behavior can be characterized as difficult to flow.
- the aim of the experiment was to produce evenly long fibers with the edge mill.
- the ground hay should later be added to the paper.
- the test result showed that the hay could be processed very well with the press type 33-390.
- the press type 33-390 was used as a pug mill to crush the hay.
- the hay was very
- the partial experiment P 1 was carried out with a type 33-390 press, with a number of rollers of 2, a speed of 166 rpm and a speed of collapse of 2.28 m / s.
- the die used was Type 821 12, with a 1: 2.0 press ratio.
- the feeding of the conveyor belt was done by shoveling, after a
- the particle size classes for smaller 1 mm are 31.2%, for the range between 1 mm and 2 mm 32.6%, for the range between 2 mm and 3.15 mm 20 , 1%, for the range between 3.15 mm and 4.0 mm at 8.8%, for the range between 4 mm and 5 mm at 5.5% and for larger 5 mm at 1, 8%.
- the cumulative grain classes are up to 1 mm at 31, 2%, up to 2 mm at 63.8%, up to 3.15 mm at 83.9%, up to 4.0 mm at 92.7%, up to 5.0 mm at 98.2% and total at 100%. Partial test A 3
- the partial test A 3 was carried out, compared to A2, with a smaller gap of 0.8 mm (compared to 3.4 mm in A2). The other parameters were unchanged compared to sub-experiment A 2.
- the sieve analysis of the final product is shown in FIG. 4:
- the particle size classes for smaller 1 mm are 35.5%, for the range between 1 mm and 2 mm 47.0%, for the range between 2 mm and 3.15 mm at 16 , 0%, for the range between 3.15 mm and 4.0 mm at 1.3%, for the range between 4 mm and 5 mm at 0.1% and for greater than 5 mm at 0.1%.
- the cumulative grain classes are up to 1 mm at 35.5%, up to 2 mm at 82.5%, up to 3.15 mm at 98.5%, up to 4.0 mm at 99.8%, up to 5.0 mm at 99.9% and total at 100%.
- the material before pressing, the material, as in P 1, had a moisture content of 9.3%, a temperature of 20 ° C. and a bulk density of 0.07 kg / dm 3 .
- the light particle size classes are 45.6% for smaller 1 mm, 50.1% for the range between 1 mm and 2 mm, 4.2% for the range between 2 mm and 3.15 mm, and larger for the range between 2 mm and 3.15 mm 3.15 mm at 0.1%.
- the cumulative grain classes are up to 1 mm at 45.6%, up to 2 mm at 95.7%, up to 3.15 mm at 99.9% and a total of 100%.
