Definitions

  • the invention is based on a press cover, in particular for a press device for treating a fibrous web, e.g. for smoothing or dewatering it, in detail according to the independent claims.
  • the invention also relates to a shoe press and the use of a press jacket in such and to a machine comprising such a shoe press, in detail according to the independent claims.
  • Press devices such as shoe presses have long been part of modern paper machines. They essentially comprise a stationary shoe (also called a press shoe), which extends in a cross-machine direction, and a press cover that encircles the stationary shoe. The latter is deformable and essentially assumes a tubular shape in operation.
  • the shoe is shaped in such a way that it forms a press nip (press nip) with a counter roller.
  • the press nip is defined by the contact surface of the counter roll in the shoe.
  • the shoe is designed to be movable and can be moved to the counter roll.
  • Press jacket should increase.
  • the press cover must therefore be sufficiently flexible so that it can be guided around the shoe, it must be sufficiently rigid so that it does not deform or compress too much in the nip under the press load, and it must be sufficiently wear-resistant.
  • Press jackets therefore consist of a single or multi-layer polymer layer, preferably made of polyurethane, in which reinforcing threads in the form of scrims or fabrics can be embedded.
  • the present invention relates to such generic objects mentioned at the outset.
  • press sleeves known from the prior art have sufficient flexibility and at the same time sufficient rigidity, their chemical resistance, in particular to water and oil, their abrasion resistance, their resistance to cracking and crack growth and their swelling behavior are in need of improvement.
  • thermoplastic elastomer in the form of a copolymer is used for a polymer layer of the press jacket.
  • Thermoplastic elastomers are - according to the definition of the Wikipedia article of the same name, last edited on July 22, 2019 at 11:13 a.m. - materials in which elastic polymer chains are embedded in thermoplastic material. They can be processed in a purely physical process in a combination of high shear forces, the action of heat and subsequent cooling.
  • Conventional elastomers are chemically wide-meshed network molecules. The cross-links cannot be broken without decomposition of the material. Although no chemical crosslinking is necessary, for example through a time-consuming and temperature-intensive vulcanization as is the case with elastomers, the parts produced have rubber-elastic properties due to their special molecular structure. Renewed exposure to heat and shear forces leads to melting and deformation of the material.
  • copolymers are polymers which are composed of two or more different types of monomer.
  • thermoplastic elastomers are divided into copolymers and elastomer alloys. Copolymers are used either as random or block copolymers.
  • the former consist of a crystallizing (and thus physically crosslinking) main polymer such as B. polyethylene, the degree of crystallization by a randomly installed along the chain comonomer such.
  • EVA in the example
  • the hard and soft segments are sharply separated in one molecule (e.g. SBS, SIS).
  • TPEs the material separates into a continuous and a discontinuous phase below a certain temperature. As soon as the latter falls below its glass transition temperature Tg (the Tg of the continuous phase is significantly below the later application temperature), it again acts as a crosslinking point.
  • Elastomer alloys are polyblends, i.e. mixtures
  • thermoplastic elastomer is preferably a segmented block copolymer.
  • a thermoplastic polyether-ester block copolymer COPE or TPE-E
  • COPA or TPE-A thermoplastic copolyamide elastomer
  • the soft segments are formed by the polyol.
  • polyesters, polybutylenetephtalates, polyethylene terephthalates, methyl terephthalates, poly (butylene 2,6 napthalene dicarboxylate, poly (butylene-co-isophthalate or aromatic polycarbonates) can be used.
  • polyamides can be used as hard segments
  • Polyether polyols, for example polytetramethylene glycol, polycarbonate polyols, polyether polycarbonate polyols, polycaprolactone polyols are particularly suitable polyols for the invention. In principle, it would be conceivable to use a polyol blend, i.e.
  • thermoplastic copolymers mentioned a thermoplastic elastomer to use urethane-based (TPU) for the at least one polymer layer of the press jacket
  • TPU urethane-based
  • the press jacket or the at least one polymer layer can be produced partially or completely from a polymer.
  • a pourable, curable, preferably elastomeric polymer such as polyurethane can be used as the polymer.
  • the polymer can consequently be set as a cast elastomer.
  • polymer layer is meant a layer which comprises such a pourable, curable, preferably elastomeric polymer or is produced entirely from it.
  • the polymer layer can preferably be a cured layer produced in one piece by primary molding. In other words, it is primordial monolithic, that is produced by, for example, casting.
  • the term “one-piece” also includes cases in which the one layer was again produced from several layers of the same material when the polymer was cast. However, this is only insofar as these layers are essentially no longer visible after curing, but rather a single, preferably uniform layer results. The same applies accordingly to the finished press jacket.
  • a plurality of polymer layers can be arranged one above the other as seen in the radial direction - at least in sections over the width of the press jacket. At least in sections across the width of the press jacket means that the press jacket is, for example, only single-layered at its axial ends along the longitudinal axis of the press jacket, whereas it has two or more layers between the axial ends.
  • the polymer layers can also extend over the entire width of the press jacket.
  • the thickness of the press jacket - and thus the thickness of the individual polymer layers - can also vary in sections along the longitudinal axis in a section through its longitudinal axis.
  • the radially outermost polymer layer in the area of the width edges of the press jacket can be smaller than in the middle of the press jacket.
  • the radially outermost polymer layer can be less thick in the region of the width edges than a radially inner or radially innermost polymer layer.
  • Precisely one, two or three polymer layers are preferably provided. These can be identical in terms of their polymer or vary in terms of their hardness or stoichiometry of the prepolymer.
  • a total thickness of the finished press jacket in a section through its longitudinal axis, measured in the radial direction, can be 5 to 10 mm, preferably 5 to 7, particularly preferably 5 to 6 mm.
  • the press jacket when a single layer is provided, can be made from only one cast, ie monolithically, so that the single layer has the thickness just mentioned.
  • a finished press jacket within the meaning of the invention is one whose at least one polymer layer is cured and possibly finally processed, that is to say for the is ready for use in a shoe press, for example.
  • a finished polymer layer means a layer that has cured.
  • a reinforcing thread within the meaning of the invention is understood to be a pliable, textile line structure that has a dominant extension and uniformity in its longitudinal direction.
  • a single, endless fiber in the manner of a monofilament is meant.
  • a fiber bundle is spoken of in the sense of the invention, it is not a question of monofilaments but, in turn, a single thread, such as a twisted thread or yarn, that is a bundle of continuous fibers or monofilaments.
  • the fiber bundles themselves can be made from fibers twisted together.
  • the definition that at least the longitudinal threads are produced as reinforcing threads according to the invention means that only the longitudinal threads are designed in this way or, in addition, the longitudinal threads and at least one further circumferential thread are produced in this way. If, for example, a scrim of circumferential and longitudinal threads is preferably present, this means that at least the longitudinal threads are designed according to the invention.
  • reinforcement structure in the context of the invention means reinforcement of the at least one layer containing or consisting of the polymer - that is to say the polymer layer. The reinforcement structure can be completely embedded in the polymer layer, so that the reinforcement structure does not go beyond the delimitation of the polymer layer.
  • the polymer layer takes on the role of a matrix which surrounds the reinforcement structure and binds to the matrix as a result of adhesive or cohesive forces.
  • a reinforcement structure can be textile line structures - z. B. yarns or twisted threads - and / or textile fabrics - such. B. fabrics, knitted fabrics, knitted fabrics, braids or scrims - comprise and can be produced from a corresponding starting material, for example by winding.
