In form of implementation, the cylinder core of CFK cylinder is by thread-shaped or carbon fiber spiral, that infiltrate with epoxy resin or the circle of carbon fiber bundle, described astragal have certain and may each layer between different helical pitches.Epoxy resin can be sneaked into filler to realize certain feature at this.After sclerosis, epoxy resin has formed matrix, and carbon fiber is embedded in described matrix.Matrix has additionally been strengthened cylinder and has been reduced vibrational energy.Due to the aggressivity steam occurring, for embedding carbon fiber, preferably use the epoxy resin that forms afterwards the matrix of heatproof and hydrolysis in sclerosis in papermaking.
In the form of implementation of explaining in Fig. 1, the coating 12 of cylinder 10 has internal coated layer, and described internal coated layer is divided into basic unit 121 and is arranged in the functional layer 122 in described basic unit.
First basic unit 121 is used to form dynamic durable being connected of cylinder core 11 and cylinder coating 12 at this.Described basic unit 121 consists essentially of the fiber strengthened resin infiltrate with filler that is wound around or is cast on cylinder core 11, hardens and then grind shaping.At present, for manufacturing basic unit, mainly use glass fabric or staple glass fibre.
The elastic characteristic of cylinder coating determined by functional layer 122 to a great extent, and described functional layer 122 is also formed by the composite with polymer substrate conventionally.Composite preferably comprises for example fibrous material of nylon fiber, glass fibre or carbon fiber, and described fibrous material can form for example bundle (fibre bundle or fibre bundle) of nonwoven silk being arranged in polymer substrate, maybe can form fabric.The material of the fiber using, diameter and bundle type have a significant effect for elasticity, mechanical stability and the heat resistance tool of functional layer.Especially, can be by the fiber combinations of different materials and different-diameter.For example, the heat resistance of composite can be by using carbon fiber improve, and nylon fiber to be composite give high mechanical strength.In addition, when using fabric and/or fibre bundle, can be by the helical pitch of thread-shaped or spiral turns the anisotropic elasticity of practical function layer 122, wherein for example the elasticity in circumferential direction is greater than the elasticity on the longitudinal direction of the symmetry axis of cylinder coating.
Can also by embed filler in polymer substrate, improve in addition elasticity and the intensity of functional layer 122.As filler, can use oxide, carbide, nitride or boride, for example silica, aluminium oxide, titanium oxide, carborundum, titanium carbide or chalk, but also can use the staple fibre of the above fibrous material providing.For forming the polymer substrate of functional layer 122, specially suitable is epoxy resin, phenolic resins, polyurethane, polyethers and polyether-ether-ketone.
In form of implementation, the thickness of basic unit 121 is chosen as in about scope of 1 to 3mm, and the thickness of functional layer 122 is chosen as in about scope of 4 to 8mm, makes the gross thickness of internal coated layer reach about scope of 5 to 11mm.Certainly, other form of implementation has the other thickness of internal coated layer, or the other thickness of formed basic unit 121 and functional layer 122, wherein its gross thickness layer structure in about scope of 2 to 10mm in about scope of 2 to 35mm and particularly preferably.
Internal coated layer being positioned in the radial direction on outside side face of cylinder 10, arranged outer covering layer, described outer covering layer has further improved the ABRASION RESISTANCE of cylinder coating 12 and has reduced on the other hand the possibility that dirt deposits on the running face of cylinder 10 on the one hand.Outer covering layer is divided into two parts, and wherein first of two parts formed by metal or ceramic blasting materials, and second of two parts is difficult to polymer attached to it by the dirt occurring in paper-making process or polyester composite forms.First component is configured to the coating of internal coated layer.
In a preferred embodiment, for manufacturing first component 123, use hot spraying method.Spray coating at this preferably in a plurality of strokes, for example in 10 to 100 strokes, carry out.Each stroke has produced the thin part layer of clad material, and wherein First layering injects directly on the outer peripheral face of internal coated layer, and other part layer is injected on each part layer previously having applied.The parameter that the physics uniformity of the coating of formation first component 123 can be passed through used method regulates.Referred to as HVOF(high-speed oxidation fuel) course of injection in, for example the formation of hole in part layer can be regulated or be avoided by the suitable transfer rate of the dusty material selecting the suitable ratio of fuel and oxygen and select be used to form layer.In addition, also can use arc spraying method.

When applied polymeric base material on first component 123 after, preferably by described polymeric base material heat cross-linking, with this, completed the formation of polymer second component 124.
As the substituting or combining with it of above-described polymeric material, also can form second component 124 with silica gel.The polymer raw materials that viscosity is lower is preferably used for forming than the relative thinner coating of second component, and for example thickness is 20 coating to about 50 μ m, and the higher polymer raw materials of viscosity is for for example until the correspondingly thicker coating of 80 μ m.
This type of layer of shape after second component 124 abrasion that applies, for example, after denuding by wearing and tearing, the remnants that retained the polymeric material that forms second component 124 due to the surface roughness of first component 123 in the depression of first component 123, the abrasion with the anti-adhewsive action of this cylinder clad surface by second component layer is maintained.
For until also maintain the anti-adhewsive action of cylinder surface while forming certain wearing and tearing of jetted layers of first component 123, in favourable form of implementation, described jetted layers being sprayed is the coating of porous.Then fill with the polymeric material of second component in the hole of coating, the matrix with this first component 123 as reception second component 124.In this form of implementation, the wear-resisting and strength characteristic of cylinder surface is the characteristics determined of first component 123 by the feature of jetted layers, and dirt adhering to substantially on cylinder surface determined by the second component of polymer.Hole produces as previously mentioned when applying clad material, and its mesopore density can regulate by the parameter of jetted layers method, and preferably forms the hole density in 2 to 10% scope.
The present invention has realized the formation of wear-resisting cylinder clad surface, and described cylinder clad surface has for the anti-adhesion effect of the dirt occurring during paper production simultaneously and therefore remains easy cleaning.
