The specific embodiment
Fig. 1 simply illustrates the stereogram of drying cylinder 10, so as explanation in the position of the working region 13 between dotted line, be arranged on the position of marginal zone 12 between dotted line and adjacent respectively chain-dotted line, working region and between chain-dotted line and the therefore position in the region 11 between marginal zone 12.Working region 13 is interpreted as the part that contacts paper fiber web in the time using in accordance with regulations of the outer peripheral face of drying cylinder 10 at this.On the fringe region of 12 working region, marginal zone 13, extend, on this fringe region, if the dry vertical edge that can cause paper or paper fiber web without countermeasure of more serious paper.The position of the rotation of drying cylinder 10 represents with chain-dotted line in Fig. 1.In introduction explanation, working region 13 does not account for the whole outer peripheral face of drying cylinder 10, and both sides have respectively narrow, fringe region that end face is arranged with regard to drying cylinder, annular.This set of working region, and non-imposed needs, thus working region 13 also can overlap with the circumferential surface of cylinder 10 in each form of implementation.The width of marginal zone 12 is for concrete structure and heating and working region 13 position and the width on the outer peripheral face of cylinder 10 of each drying cylinder.The width of marginal zone is generally in 20 to 50mm scope roughly, preferably in 30 to 40mm scope.
As already described above, the surface in working region edge region 12 is different from the surface in the region 11 between marginal zone, and wherein, the adhesion in paper fiber web edge region 12 is less than the adhesion in the region 11 between marginal zone.Correspondingly, for take the traction force F in the required edge region of paper web face 12 off from working region 13
abe less than the traction force in the region between edge region, to avoid the stretching that causes vertical edge at paper fiber web edge.
For this purpose, marginal zone 12 is provided with coating 14 as shown at Fig. 2 to 4, and its surface characteristic is different from the surperficial surface characteristic of the working region 13 between marginal zone 12.Coating 14 between the different design in region 11 can be by selecting different materials, different structures or different structure and combination of different materials are realized.Briefly, marginal zone coating 14 or be different from the design that therebetween region is relevant in its chemical composition or at its physics or the design on both.
In Fig. 2, the first form of implementation of the drying cylinder with independent marginal zone coating 14 is described.Marginal zone coating 14 is arranged in the recess of marginal zone 12 that comprises working region 13.If working region 13 does not extend beyond the edge of the outer peripheral face of drying cylinder 10, the recess of filling with coating 14 also extends in the peripheral surface region not covered by working region 13; In some forms of implementation, also stretch to each outer edge of outer peripheral face.
For the form of implementation at the drying cylinder with independent marginal zone coating 14 illustrated in fig. 3, give the whole face coat of working region 13, wherein, the coating 14 of marginal zone is in the textural coating 15 being different between the coating of marginal zone of chemistry or physics.
The special moulding of the form of implementation of Fig. 3 is pressed in Fig. 4 explanation, and wherein, two coatings 14 and 15 have microstructure different, different aperture degree form.There is space in porosity, its size is no more than hundreds of microns in this is interpreted as material.Hole is shown in this figure is dark structure, and wherein, the size of this structure and density obviously illustrate turgidly in order to hold intelligible description.Microstructure is interpreted as coating structure or general material structure structurally structurally in the document.
For being used to form marginal zone coating 14 by comparing the different material in all the other working regions 11, preferably select its surface molecular that the attraction less than the surface molecular of all the other working regions 11 is applied to the material on paper web face molecule, to be less than the traction force in all the other working regions 11 for taking the required traction force in marginal zone coating 14 of paper web face off.Traction force F on the axial dimension of the outer peripheral face of drying cylinder 10
athe example of synthetic variation is shown in Figure 5.Diagram provides the change curve of traction force quantitatively again, and wherein, the zero level of traction force is positioned at the axially extended x axis below along drying cylinder.Marginal zone coating 14 extends on the edge of cylindrical periphery face in the embodiment based on Fig. 5.Change curve has shown traction force transition gradually on the border between marginal zone coating and therebetween region 11, can avoid the unexpected variation of tension force in the time taking paper web face off by this transition.Corresponding classification can be for example by changing the composition of the coating in edge region or realizing by marginal zone coating and the interstructural combination of neighboring region 11.The graded of traction force needn't be limited to the zonule at the transition part place between marginal zone 12 and therebetween region as illustrated in fig. 5, but also can in some forms of implementation, on the whole width of cylinder, extend, wherein, on cylinder width, change so continuously, always there is the value less than the zone line of cylinder 10 at the traction force of cylinder edge.
For some forms of implementation, coating is formed by polymer.For this reason, use that especially thermosetting plastics and thermoplastic are as polymer, they can be based on one pack system and two-component system manufacture.Especially its decomposition temperature being applicable to, higher than the many like this thermosetting plasticses of the temperature of marginal zone coating, shows as each thermosetting plastics flexible.In a similar manner, suitable is its glass transition temperature is higher than the many like this thermoplastics of the serviceability temperature of marginal zone coating, makes in the time of the region using with polymer coating, there will not be softening that polymer disturbs.As being appointed as 20 ℃ for the rough approximation value of lowest difference between serviceability temperature and decomposition or glass transition temperature.Serviceability temperature is interpreted as the generally operating temperature in the time using in accordance with regulations of outer peripheral face of marginal zone coating or drying cylinder.
At least by using polyepoxide, silicon polymer or fluoropolymer to be preferably formed marginal zone coating 14.Also can use the polymeric blends that contains this material.Especially also can in described polymer, embed filler, for example fiber or particle, so that known manner is set as for example elasticity, scuff resistance, thermal conductivity or appearance color the value of expecting.
For example can use and be embedded with by polyvinyl fluoride in order to form marginal zone coating 14, the epoxy resin of the filler particles that especially polytetrafluoroethylene (PTFE) forms.Epoxy resin shows the wettability that steel surface is good and therefore allows to be connected securely with the roller core of drying cylinder in non-crosslinked or partial cross-linked state.The viscosity of epoxy resin can be passed through solvent, and the interpolation of for example alcohol or ketone and reducing for example can realize the surface of flooding for example porous thus.Coating can by casting, spraying or by spreading implement, for example brush or perching knife be implemented.The dipping of the thermally sprayed coating of the porous for example, applying before can also be undertaken by dipping bath.
There is the anti-adhesion characteristic of higher chemistry and heat endurance and excellence by the marginal zone coating of fluoropolymer manufacture.In addition the marginal zone coating 14 being formed by fluoropolymer, is also very solid under dynamic load.Silicon polymer, the silicones for the silicone oil that improves anti-stick effect for example with in its matrix combination is also suitable for forming marginal zone coating 14, because it has excellent heat resistance and chemical stability.
The anti-stick effect of marginal zone coating can be passed through the selection support of material, and these materials have the less heat conductivility in surface of comparing the drying cylinder between marginal zone coating 14 10.Corresponding less heat conductivility reduces to conduct heat and reduce thus the dry of paper web face edge by this region of roll sleeve, thereby result paper web face can stick on roller shell more weakly and more easily take off from it.Be designed to the scheme of steel cylinder for drying cylinder, this effect can be by being used for example pottery and above-mentioned polymeric material to realize.Especially for the latter, adhesion that other working faces 11 are less is compared by realizing in conjunction with two effects in paper web face edge in marginal zone coating 14: less attraction and to heat transfer still less on paper web face on the molecule of paper fiber web.
The heat conductivility of coating is except affecting by the microstructure that can also pass through coating selection coating material.For example the two or more materials of different heat conductivilitys can be arranged in abreast to the inside of marginal zone coating with complementary pattern, to form coating average heat conductivility in unit are share.Can be by the material arrangements with less heat conductivility in lower floor for example for the hierarchy of marginal zone coating, to keep as far as possible little heat conduction, and superficial layer is designed to that paper fiber web molecule is especially had to little attraction.The microstructure that marginal zone coating 14 is different also can be expressed by the material porosity that is different from all the other working faces 11.
For this purpose, marginal zone coating 14 for example can be formed by thermally sprayed coating.The coating of coating material is preferably by being used heat spraying method to carry out, and the known HVOF (High Velocity Oxygen Fuel) of HVOF that for example adopts to abridge is carried out.Be sprayed on this preferably with multiple strokes, for example 10 to 100 strokes carry out, and wherein, each stroke is coated to the coating material of thin layer respectively on the material that is positioned at below.The porosity of this layer can regulate by the transfer rate of fuel and the ratio of oxygen and the dusty material by being used to form layer.Can change the porosity in the degree of depth of marginal zone coating 14 by layer to the parameter change of layer.Between the porosity of marginal zone coating 14 is preferably 2 to 10% or in the time of preferred this intra-zone cross direction profiles, change, wherein, porosity is interpreted as and is running through the unit are share of cross section mesopore of this material.In order further to reduce the bonding force of paper fiber web in the marginal zone of corresponding porous coating 14, its hole is flooded with polymeric material described above, that is, fill.
What be applicable to as thermal spraying is metal-cermic coating, for example carbide alloy, wherein, tungsten carbide particle is bonded in Cr-Ni matter, but also has ferrous alloy and based on for example oxide ceramic material, as the ceramic layer of aluminium oxide, zirconia, magnesia, chromium oxide, yittrium oxide and titanate etc.
For in the form of implementation shown in Fig. 4, whole working face covers with thermally sprayed coating, in preferred form of implementation, covers with hard alloy layer, and wherein, the porosity of marginal zone coating 14 is higher than the region between them 11 of all the other working faces 13.Ideally, the porosity of coating 15 in region 11 equals zero.In fact, attainable minimal amount of porosity is relevant with heat spraying method and coating material used respectively.Being less than 1% drops to 0.5% porosity and can realize completely at present.In the time forming marginal zone coating 14, coating parameter is set as, and porosity is reached roughly in 2 to 10% scope.For particularly preferred form of implementation, then fill with above-mentioned polymeric material in dipping process in the hole of marginal zone coating 14.For other favourable form of implementation, the surface of marginal zone coating 14 is with described polymeric material mulched ground coating, and wherein, the outer surface of polymer coating is arranged on the outer surface of coating 15 aptly equably.
For having on its whole width (that is, on its whole axial length) drying cylinder of continually varying temperature cross direction profiles, marginal zone coating 14 is not only extended on the region that is defined as marginal zone 12, and extends in whole or at least one major part of working region 13 that contacts paper web face to be dried.For this reason, can give the surperficial jacket of drying cylinder with thermally sprayed coating, its porosity reduces to its zone line continuously from the fringe region of cylinder 10.The axial adhesion cross directional variations causing thus can be strengthened by dipping described before the coating of porous.
The drying cylinder of the above-mentioned type prevented when cylinder, especially drying cylinder are taken paper fiber web off its edge effect than all the other breadths on larger power.Therefore, just expend with little equipment the setting that has effectively overcome paper web face edge.The present invention not only can be used for drying cylinder, but also for other cylinder in drying section or paper machine other parts.
