Definitions
- the present invention relates to an elastic smoothing roller, in particular for smoothing paper webs, with a hard roller core and one provided on the outside of the roll core, multilayered trained elastic matrix material comprising elastic matrix layer. Furthermore, the invention relates to a method for manufacturing directed such an elastic smoothing roller.
- Elastic rollers 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 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 evened out and compressed in press nip.
- the size of the rollers is 3 to 12 meters in length and 450 to 1500 millimeters in diameter. They withstand line forces of up to 600 N / mm and compressive stresses of up to 130 N / mm 2 .
- plastic coverings maximum temperature differences of about 20 ° C over the Width of the roller permitted and on the other hand have that for the coating
- plastics used are much higher Thermal expansion coefficients than those commonly used Steel rollers or chill cast rollers, so that by an increase in temperature high axial tensions between the steel roller respectively Chilled cast roller and the plastic coating connected to it occur.
- powdery fillers and / or fibers in the matrix material contribute.
- the elastic reference layer of the fillers or Fibers dominate or influence. Due to the powdery or fibrous fillers is often the smoothness of the Surface of the elastic roller deteriorated. This is undesirable because the paper quality directly from the smoothness of the surface of the smoothing roller depends.
- reference layers made of plastic material have a relative low abrasion resistance, so the life of the corresponding Smoothing rolls are often not sufficient. Because of the used There is also the risk that plastics for the reference layer in operation due to the existing friction between the plastic roller and the elastic smoothing roller is statically charged to the paper web to be smoothed which creates the risk of being charged attracted particles, such as dust particles or the like, on the surface of the smoothing roller and thus a reduction in the smoothing quality or in the worst case, even damage to the roller coating cause.
- a smoothing roller is known from DE 199 25 419 A1, in which additionally to the outer plastic layer a covering this plastic layer metallic reference layer is provided.
- the metallic Outer layer by winding up coated with liquid metal Fibers created on the elastic plastic layer. Because of the used Fibers as a carrier for the metal coating is the smoothness of this Roller depending on the fiber diameter used.
- the part of the task relating to the smoothing roller is invented based on a smoothing roller of the type mentioned solved that the elastic reference layer has a radially inner, with Fibers reinforced base layer, the coefficient of thermal expansion and the elastic modulus of the base layer through the Fibers the coefficient of thermal expansion and the modulus of elasticity of the roll core are approximated that an elastic middle layer is provided whose modulus of elasticity is smaller than the modulus of elasticity the base layer that a radially outer layer is provided is made from a mixture of molten metal and molten metal Plastic is made, and that the coefficient of thermal expansion and the modulus of elasticity of the middle layer at least in its radially outer area to the coefficient of thermal expansion and the elastic modulus of the outer layer are approximated.
- the inventive method is characterized in that the from a mixture of molten metal and molten metal Plastic existing outer layer by a spray, pour, brush or Painting process is applied to the middle layer.
- the advantages of the different known methods combined, by firstly the outer layer made of a mixture of metal and plastic is produced and the other by a corresponding Design of the remaining shifts occurring in the company Longitudinal stresses between the individual layers of the reference layer can be reduced or, in the best case, completely avoided.
- Farther are in addition to the pure combination of metal and plastic to form the outer layer both the metal and the plastic each melted together on the surface applied to the roll core, which achieves significant advantages become.
- powdery Metal particles with a liquid plastic matrix material has a mixture of molten metal and molten plastic a much more homogeneous structure and thus increased strength. Furthermore, it is avoided that in particles arranged in the matrix material Crystallization points for hot spots arise, which lead to destruction of the roll cover layer could.
- the physical properties of the reference layer are like For example, abrasion resistance and smoothness are optimally homogeneous across the entire reference layer available.
- the smoothness of the reference layer can be extremely high, for example by grinding and subsequent Polishing can be set as there are no particles, whether in Powder form, in fiber form or in another form, in the matrix material are present that ultimately increase on the surface of the reference layer an undesirable roughness.
- the roller produced according to the invention has one opposite a roller with a plastic layer, significantly improved thermal conductivity, so that the heat occurring during operation is dissipated very quickly and thus further reduces the risk of hot spots occurring can be.
- the outer layer is essentially fiber-free.
- the smoothness can go through Grinding and / or polishing the surface can be optimized.
- Prefers the surface of the outer layer has an Ra value that is less than 0.05 ⁇ m, in particular less than 0.03 ⁇ m.
- the outer layer uses an abrasion resistant metal.
- abrasion resistant metal used, the longer the lifespan of a corresponding one trained roller, so the profitability of such Roller can be significantly improved.
- a plastic High-performance plastic i.e. a plastic with a high melting point, in particular a polyimide (PI), polyamideimide (PAI), polyetherimide (PEI), Polysulfone (PSU, PES), polyether sulfone (PESU) or a polyphene sulfone (PPSU), a mixture of one or more high-performance plastics with other plastics or a mixture of high-performance plastics used.
- PI polyimide
- PAI polyamideimide
- PEI polyetherimide
- PSU Polysulfone
- PES polyether sulfone
- PPSU polyphene sulfone
- a plastic for the outer layer or a plastic mixture with a melting point of more than approx. 300 ° C, in particular more than approx. 400 ° C, preferably approx. 500 ° C or more and / or with a modulus of elasticity of less than about 4 GPa, preferably of about 3.5 GPa or less is used.
- the Middle layer much thicker than the outer layer and / or than that Base layer formed.
- an appropriate thickness of the middle layer is a "soft" course of the essential physical properties such as coefficient of thermal expansion and modulus of elasticity the radial thickness of the reference layer is adjustable. This prevents that due to voltages or temperature differences occurring during operation individual layers are detached from one another.
- the outer layer has a high thermal conductivity. This ensures that heat occurring during operation quickly and reliably from the respective overheating point can be derived.
- the middle layer at least in some areas fibers. It is about preferably fibers with a relatively high thermal conductivity, the Number within the middle layer can be so radially variable that the Thermal conductivity of the middle layer increases radially outwards until it at the transition to the outer layer almost equal to the thermal conductivity the outer layer is. Furthermore, the elasticity module can be used with the fibers increasing radially outwards and / or the coefficient of thermal expansion can be adjusted to decrease radially outward to achieve an alignment with the outer layer. For example achieved by using carbon fibers in the middle layer become.
- the fibers of the base layer are at least partially aramid and / or Glass fibers.
- the fibers are preferred as rovings on the roll core wrapped and embedded in the elastic matrix material of the base layer.
- the material and the amount of fibers are selected so that the temperature coefficient and the elastic model in the radial inside lying area of the base layer to the corresponding parameters of the Roll core are approximated.
- the amount of the Fibers chosen so that a smooth transition of these parameters to the Middle class is given.
- the matrix material can preferably be designed as a resin-hardener combination be and include, for example, epoxy resin.
- the roller core can be made of metal or in particular fiber-reinforced plastic.
- the use of a plastic roller as a roller core has the advantage that the weight and thus the Inertia of the smoothing roller compared to the use of a metal core can be significantly reduced. Especially those that occur during operation high rotational speeds is the reduction of the roller weight advantageous.
- the use of in particular fiber-reinforced Plastic rollers especially for so-called wide nip calenders advantageous because a plastic roller core over a metallic Roll core has a certain flexibility, which is an evenness causes the paper web in the nip.
- the outer layer is processed using a flame or plasma spraying process applied to the roll core.
- a flame or plasma spraying process applied to the roll core.
- Flame or plasma spraying can be very high quality Creates outer layers and a very firm connection of these outer layers be made with the middle class.
- the metal and / or the plastic during the flame or Plasma spraying melted.
- the metal and / or the Plastic as a starting material, for example in powder form are present and only in liquid during flame or plasma spraying Condition to be transferred. In principle, however, it is also possible that the metal and plastic before being applied to the roll core melted and mixed together.
- the method according to the invention is also a very good one Possibility to repair the smoothing rollers. So the outer layer after corresponding damage to the surface, for example simply by spraying a mixture of molten material according to the invention Metal and molten plastic - optionally via the entire surface of the roller or only in the area of damage - in can be easily repaired. Removing the roller from the Calender, which would be associated with correspondingly long downtimes, is not necessary, so that also through the possibility of repair the economy of a corresponding calender significantly improved can be.
- the figure shows a schematic cross section through an inventive trained smoothing roller.
- the smoothing roller shown includes one for example made of metal or fiber-reinforced plastic, for example Polymer, existing roll core 1, which is rotatable about an axis of rotation 2 is stored.
- metal or fiber-reinforced plastic for example Polymer
- existing roll core 1 which is rotatable about an axis of rotation 2 is stored.
- carbon, aramid, Glass fibers or other suitable fibers are used.
- a relatively thin base layer 3 On the outside of the roll core 1 is a relatively thin base layer 3 provided, which is made of a fiber-reinforced elastic matrix material consists.
- the material, the number and the orientation of the fibers are chosen so that the temperature expansion coefficient of the Base layer 3 at least approximately in its radially inner region is as large as the thermal expansion coefficient of the roll core 1.
- the base layer 3 is followed by a middle layer 4, which is essential is thicker than the base layer 3.
- This middle layer 4 can as a continuation of the base layer 3 also made of fiber reinforced Matrix material exist. Because of the thickness of the middle layer 4 essentially determines the elasticity of the entire reference layer the number of fibers within the middle layer 4 is opposite the base layer 3 is usually significantly reduced, so that the modulus of elasticity the middle layer 4 is lower than the elastic modulus Base layer 3.
- the middle layer 4 is in turn in a radially inner region 5 and divided a radially outer region 6, which in the figure are separated from one another by a dashed line 7. While through the matrix material used and the fibers embedded in it radially inward area 5 the ultimate elasticity of the Whole roll is essentially determined, forms the radially outside lying area 6 a transition area to a surface 8 of the Roller-forming outer layer 9.
- the area 6 of the middle layer 4 is formed significantly thinner than area 5 and contains fibers embedded in the matrix material, by approximating the modulus of elasticity and the coefficient of thermal expansion to the corresponding parameters of the outer layer 9 takes place.
- the fibers can vary radially outwards, in particular, be increasingly distributed in order to be as continuous as possible To achieve approximation of the parameters mentioned.
- the outer layer 9 is designed as a thin elastic layer, the according to the invention from a mixture of molten metal and molten plastic.
- the outer layer 9 is therefore continuous homogeneous and has, for example, due to a performed grinding and / or polishing an extremely smooth Surface 8.
- the mixture of molten metal and molten plastic can, for example, as indicated schematically, by a Flame spray device 10 applied to the surface of the middle layer 4 become.
- the coating can be applied by rotating the roller core 1 and the flame spray device 10 slowly in the axial direction parallel to the axis of rotation 2 is moved.
- Starting materials metal / plastic
- Heat is converted into a liquid state and mixed together
- the two starting materials already exist in a liquid state through pretreatment and by a simple spraying, pouring or painting process on the surface of the roller core are applied.
