Definitions
- the present invention relates to a roller, in particular for smoothing of paper webs, with a hard one consisting in particular of metal Roll core, on the outside with an elastic reference layer is provided, which is made of an elastic matrix material and in the Matrix material consists of embedded fibers. Furthermore, the invention directed to a method of making such a roller.
- Elastic rolls of this type are used, for example, when satinizing paper webs.
- An elastic roller forms a press nip together with a hard roller through which the paper web to be processed is passed. While the hard roller has a very smooth surface, for example made of steel or chilled cast iron, and is responsible for smoothing the side of the paper web facing it, the elastic roller acting on the opposite side of the paper web causes the paper web to be leveled and compressed in the press nip.
- the size of the rollers is between 3 m and 12 m and diameters from 450 mm to 1500 mm. They withstand line forces up to 600 N / mm and compressive stresses up to 130 N / mm 2 .
- fillers for example in the form of fibers or powder in introduced the matrix material.
- these fillers have the physical properties of elastic Reference layer dominated or influenced by the fillers.
- the thermal conductivity of the elastic reference layer by using fillers with a high thermal conductivity be improved.
- the smoothness of the surface of the reference layer is usually achieved by appropriate grinding and polishing of the reference layer is achieved.
- the size of the fillers commonly used is only a limited smoothness of the surface of the reference layer can be achieved.
- For example typically have fibers previously used as fillers Diameter between 8 ⁇ m to 20 ⁇ m. Because when sanding the surface these fillers come to rest on the surface and partially this leak is the smoothness of the surface of known elastic Rolls much lower than the smoothness of the known hard rolls.
- this task solved according to the invention in that the diameter of the fibers is less than 800 nm, so that the surface of the elastic reference layer an extremely high smoothness, in particular an Ra value of below has about 0.6 ⁇ m that the thickness of the elastic reference layer between 3 and 20 mm and that in addition to the matrix material Fibers powdered fillers are embedded, their external dimensions are smaller than 1 ⁇ m at least in one direction.
- a corresponding method is characterized in that for generation an extremely high smoothness of the elastic reference layer, in particular an Ra value of less than approx. 0.6 ⁇ m into the elastic matrix material essentially only fibers are introduced whose Diameters less than 800 nm are powdered in addition to the fibers Fillers are introduced into the matrix material, the outer Dimensions at least in one direction each less than 1 ⁇ m and that the elastic reference layer with a thickness of between 3 and 20 mm is formed.
- the fillers due to the small dimensions of the fillers, one is essential finer distribution of the fillers within the reference layer possible, whereby both a better thermal conductivity as well higher strength of the reference layer is achieved.
- the improved thermal conductivity leads to the high temperatures that occur during operation, especially at fault points, can be removed very quickly, so that the occurrence of hot spots is largely prevented.
- the higher strength due to the better homogeneity of the reference layer material is achieved leads to a reduction in the probability of occurrence of hot spots.
- the improved thermal conductivity is achieved in particular by that due to the reduced dimensions of the fillers, a higher packing density the fillers can be achieved. With this increased packing density the amount of what is between the fillers, usually has a low thermal conductivity matrix material reduced so that the overall thermal conductivity of the elastic reference layer is improved.
- the formed in these between the fibers free powder areas arranged powdery fillers cause moreover, that these areas also have increased thermal conductivity have, with the chosen dimensions of the powder Fillers the extremely high smoothness of the reference layer is preserved.
- the number of required smoothing gaps can be reduced, as on the elastic Roll associated side of the paper web a high smoothness of the paper web can be achieved and not, as with the known rollers, by the elastic roller the smoothing result previously achieved by the hard roller deteriorates again.
- Diameter of the fibers smaller than approx. 500 nm, in particular smaller than approx. 200 nm.
- the smaller the diameter of the fibers chosen the more the surface of the reference layer is smoother and associated with it the more the smoothing result is better.
- This also applies to the powdery Fillers, so that preferably the outer dimensions of the powder Fillers at least in one direction less than 800 nm, in particular are smaller than approx. 500 nm, preferably smaller than approx. 200 nm.
- the fibers are preferably designed as carbon, aramid or glass fibers. A mixture of these fibers is also possible.
- the powdery Fillers are preferably made from the same material as the fibers, can in principle also be made from other materials with high There is thermal conductivity.
- the fibers can advantageously together connected, for example twisted or entangled, and advantageous in Form of fiber rovings or a non-woven fabric are present. Through the connection e.g. approx. 10 mm or less long fibers are combined with the increased packing density an improved thermal conductivity compared to conventional reference layers.
- the diameter is predominant for the desired surface smoothness of the fiber is decisive if the largest proportion of the fibers is used for grinding with one of its ends from the surface of the reference layer protrudes.
- the smaller the diameter of the fibers the higher thus the surface smoothness of the reference layer after grinding and Polishing.
- Most of the fibers lie with their long sides against the Surface of the reference layer, because of the reduced thickness Surface smoothness compared to conventional reference layers as well improved even if the length of the fibers is chosen as usual.
- the use of carbon fibers is advantageous in that it is a good one Have thermal conductivity. This is a quick heat dissipation guaranteed by the carbon fibers when the roller is heated during operation.
- the fillers can preferably be distributed uniformly in the matrix material be, due to the small size of the fillers a very homogeneous Mixture and associated very high strength of the reference layer with a very good thermal conductivity.
- the improved thermal conductivity is achieved in particular in that the material of the fillers is chosen so that it has a higher thermal conductivity than the matrix material has.
- the surface of the elastic reference layer has an Ra value of less than approx. 0.5 ⁇ m, in particular less than about 0.2 ⁇ m, preferably less than about 0.1 microns. So that the elastic roller has a surface smoothness in the The magnitude of the surface smoothness of the hard roller is so that when Going through a smoothing gap essentially both sides of the paper web be smoothed with the same quality. Depending on the desired result can therefore apply to some or almost all of the smoothing nips of a multi-roll calender be dispensed with, so that in the best case with a single Smoothing gap a sufficient smoothing result is achieved.
- the elastic roller can be produced in a known manner, for example by spraying, pouring or winding processes on the roll core, according to the invention extremely small powdery fillers and extremely thin fibers introduced into the elastic matrix material or be coated with this in a winding process.
- the fibers can preferably be in the form of fiber rovings, so that accordingly the extremely thin diameter of the fibers extremely thin Layers of fiber rovings can be wound on the roll core. These are preferred before or during winding with the matrix material impregnated or after winding on the roll core with applied to the matrix material.
- the use of a is also advantageous Non-woven fabric that ensures good thermal conductivity and in can be impregnated with the matrix material in the same way.
- Fig. 1 shows a part of a cut in the longitudinal direction, for example existing steel or cast iron roll core 10, the outside with an elastic reference layer, also shown in section 12 is provided.
- the reference layer 12 consists of an elastic matrix material 16, in the particulate fillers 17, for example in powder form are.
- the particulate fillers 17 have diameters of less than 1 ⁇ m, the diameter preferably less than 800 nm, in particular less than 500 nm and advantageously even less than 200 nm is.
- the powdery fillers 17 are in corresponding Extremely thin fibers 19 embedded in the matrix material, such as they are shown in Fig. 2. For reasons of clarity, they are Fibers 19 not shown in Fig. 1.
- the fillers 17 can, as in the left half of Figure 1 schematically shown, distributed substantially uniformly over the reference layer 12 be or, as in the right, separated by a dashed line 18 Half of Figure 1 shown, so distributed within the reference layer 12 be that the concentration of the fillers 17 decreases radially outwards.
- the physical properties for example, coefficient of thermal expansion, thermal conductivity, Elasticity, etc., the reference layer 12 in the radially inner Area dominated by the fillers more than in the radially outer Area.
- the coefficient of thermal expansion in the radially inner area of the reference layer 12 at the coefficient of thermal expansion of the roll core 10 are adjusted so that longitudinal stresses occurring during operation due to uneven expansion of roller core 10 and reference layer 12 can be compensated.
- the thermal conductivity in the radially inner area of the Reference layer 12 can be increased by the embedded fillers 17, so that especially in the area between the roll core 10 and the reference layer 12 excess heat quickly dissipated laterally can be.
- FIG. 2 shows the fibers 19 arranged in the matrix material 16, which are designed in particular as carbon fibers. While in the left half of Figure 2, the fibers 19 again uniformly within the reference layer 12 are arranged distributed in the by dashed line 18 separate right half a distribution of fibers 19th shown, which is similar to the distribution of powdered particles 17 in Figure 1 decreases radially outwards. This will already make them the Figure 1 achieved advantages achieved. Between the fibers 19 are the powdery fillers 17 schematically indicated.
- the formation of the fillers as fibers 19 has the advantage that depending on Length of the fibers 19 in each case the inside of the reference layer 12 Heat without interruption through the elastic matrix material 16 can be dissipated quickly. In addition, a higher rigidity of the reference layer 12 can be achieved.
- the fibers 19 have a diameter of less than 800 nm, in particular of less than 500 nm or even less than 200 nm. Because of this extreme As already described for FIG. 1, the fibers are made thin, an extremely smooth surface 20 of the reference layer 12 after grinding and polishing achieved. Because the fibers 19 usually have one of their ends extend to the surface 20 of the reference layer 12 or minimal protrude from this, as it is exemplified in Fig. 2 by the 19 ' Fibers can be seen, the smoothness of the surface 20 determined by the diameter of the fibers 19 '. Because of the extreme small diameter of the fibers 19 of less than 1 micron is thus a extremely smooth surface of the reference layer 12 after grinding and Polishing achieved in the area of smoothness of the surface of a hard Rolling lies.
- a roller according to the invention can also by other manufacturing processes, for example spraying, pouring or other suitable processes are produced.
- a large number of fiber bundles 7 are combined Fibers, especially in the form of a fiber roving through a schematically shown coating device 8 out.
- the coating device 8 the individual fibers with a liquid Matrix material 16 coated so that the fibers essentially are completely embedded in the matrix material 16.
- the matrix material 16 can be a plastic, in particular a plastic Trade resin / hardener combination.
- additional fillers for example in the form of powder Fillers 17 may be provided, the dimensions of which are all smaller than Are 1 ⁇ m.
- This wrapping process can be repeated several times until a reference layer 12 is produced with a sufficient thickness of 3 to 20 mm. Subsequently the reference layer 12 can be used to achieve an extremely smooth Surface can be sanded and polished, whereby the extremely small Dimensions of the fibers or the additional fillers an extreme smooth surface of the reference layer 12 is obtained.
- a reference layer according to the invention compared to a conventional one Reference layer recognizable. Only those embedded in the matrix material are included Fibers shown, for example when using a nonwoven fabric aligned essentially in the circumferential direction of the roller are.
- the right half of the Fig. 4 shows a cross section through fibers 19 with the invention reduced Diameter. Due to the reduced diameter and thus associated increased packing density of the fibers 19 is in the invention Reference layer between the fibers 19 less matrix material 16 than between the fibers 19 ". In addition, in this Matrix material 16 which are also extremely small powdery fillers 17 present, which has good heat conduction between the individual fibers cause. Because the thermal conductivity of the matrix material 16 is usually is significantly worse than the thermal conductivity of the fiber material thus the reference layer 12 according to the invention has an improved overall thermal conductivity.
