Abstract

The invention relates to a method for producing components by joining ceramic components and / or metallic components and a component produced by this method.
The components are produced by joining ceramic components and / or metallic components, wherein the joining components to assemblies and / or components using fully fluorinated solid polymers, which may be present as a film, sleeve or in any other geometric shape, are assembled and this one thermal treatment process with a bonding temperature above the melting temperature of the vollflouriertem solid polymer at a contact pressure below the breaking limit load of the material of the joining components and a holding time of less than 1 hour are subjected.

Description

  • The invention relates to a method for producing components by joining ceramic components and / or metallic components and a component produced by this method.
  • In plant engineering and mechanical engineering, components made of ceramic material are used wherever corrosion and high temperatures, but also high purity requirements occur. As a representative of technical ceramics, silicon carbide (chemically named SiC, technically referred to as SSiC in its directly sintered modification) has very good corrosion resistance, very good thermal shock resistance, and high thermal conductivity unlike various metallic materials. Silicon carbide is therefore predestined as a material for the production of heat exchangers in the corrosive as well as in the ultra pure chemical sector.
  • Basically, two different compounds of SiC components are used in the production of heat exchangers, which are composed of individual plates, connecting parts, etc., on the one hand, the non-positive connection and on the other the cohesive connection.
  • From the DE 32 00 200 For example, a process is known in which a layer of metal boride is applied to the metal carbide moldings and these are then juxtaposed with their bonding surfaces, pressed together and then heated to form a sintered composite article.
  • A further development is the in DE 10 2008 019 556 A1 This publication presents a cohesive joining of such heat exchangers and microreactors consisting of thin SiC plates. The plate thicknesses are in the range up to a maximum of 20 mm, but predominantly between 3 to 6 mm. With the cohesive connection of the small SiC plates, a less complex component preparation with respect to parallelism is sought. Suitable adhesives are preferably one-component epoxy and silicone adhesives. The problem with this type of cohesive connection is the uniform application of the adhesive layer, which is why certain viscosity values are specified for this purpose. In addition, these adhesives require relatively long curing times. About the brittleness of the cured joint connection no information is given. The compounds are soluble by burnout (thermal decomposition) of the adhesive at about 500 ° C.
  • The main drawback of this process, however, is that the types of adhesives incorporated in the claims do not correspond in their chemical resistance to the level of SiC. Thus, components added on this basis have a weak point in chemical resistance lower than that of SiC ceramics.
  • Furthermore, there are cohesive connections in which the individual SiC components are connected to one another, for example, by diffusion welding.
  • The DE 10 2004 044 942 A1 describes a method for joining SiC components by diffusion bonding, wherein the components are joined to a monolith in a low-deformation manner. Diffusion-welded monolithic blocks have a high rigidity and a high risk of thermal shock due to possible significant thermal stresses.
  • From the DE 10 2006 013 503 A1 is a plate heat exchanger, a process for its preparation and its application known. The plate heat exchanger consists of a plurality of plates, preferably of sintered ceramic material, in which fluid flow guide channels are formed as a channel system so that a substantially meandering course of the fluid flow results over the surface of the respective plate, wherein the side walls of the guide channels a plurality of Have breakthroughs that lead to a turbulence of the fluid flow. Furthermore, the invention relates to a method for producing such a plate heat exchanger, in particular a diffusion welding method in which the plates are joined to form a seamless monolithic block.
  • From the DE 10 2008 019 556 A1 is a component of a stack of cohesively bonded plates and a method for its production known. The component is formed from a plurality of stacked plates with fluid flow guide channels, wherein the plates are materially joined by means of a least 25 microns thick adhesive layer of a polymeric adhesive. The associated method comprises the steps
    • - Applying a polymeric adhesive, for example by rolling, rolling, knife coating, spatula or screen printing on at least one of the adhesive surfaces of the plates to be joined;
    • - Stacking of the plates to be joined;
    • - compressing the plates and fixing the plate stack;
    • - Curing the polymeric adhesive while maintaining the fixation in such a way that a minimum thickness of the adhesive layer of 25 microns is not exceeded.
  • This solution has the disadvantage that the adhesive layer thickness can not be applied uniformly or that the adhesive enters the fluid flow guide channels during compression of the plate stack and thereby can form constrictions. Furthermore, dirt particles can accumulate on the exiting adhesive surpluses and thus impair the flow of fluid through the guide channels.
  • In shell and tube heat exchangers, there is the problem of sealing the tubes made of ceramic material in the tube sheets. Here come to seal on the one stuffing box, for example from the DE 33 10 986 A1 known) or on the other ring seals that are clamped between two tubesheet plates (for example, from DE 197 14 432 A1 known) are used.
  • The disadvantages are that a large number of glands are needed and the design and the workload are very high. The other solution requires double tubesheets.
  • Furthermore, in heat exchangers made of ceramic material, the problem of greatly varying material thicknesses, especially in the bottom and / or top parts. This leads to problems in the sintering process. This is where the invention starts.
  • The object of the invention is to provide a method for producing components by joining ceramic components and / or metallic components and a component produced by this method, with which the disadvantages described above are eliminated.
  • According to the invention the object is achieved by a method for producing components by joining ceramic components with ceramic, metallic or plastic components with the method steps in that
    • - The joining components are assembled into assemblies and / or components using fully fluorinated solid polymers, and
    • - These are subjected to a thermal treatment process with a bonding temperature above the melting temperature of the fully fluorinated solid polymer at a contact pressure below the breaking limit load of the material of the joining components and a holding time of less than 1 hour.
  • The thermal treatment process is carried out by complete or partial introduction of the joining temperature in the joining components, wherein the heating and / or cooling process takes place at spatial temperature gradients of less than 2 degrees / mm. Optionally, the joining components may be provided with a strength enhancing nanosheet of a primer.
  • The individual joining components are joined by means of a fully fluorinated solid polymer, which is arranged between adjacent components, under pressure and temperature. The fully fluorinated solid polymer as a hot-melt adhesive material can be present as a film, sleeve or in any given geometric shape of the joining problem. Individual components may be partially or completely coated with the fully fluorinated solid polymer. The adhesive strength of the melt-adhesive material is above the maximum pressure load (operating pressure) in the component.
  • The components of the component made of ceramic material have a disk-shaped, tubular and / or block-like construction in any geometry and the disks, tubes and / or blocks are bonded by means of an intermediate melt-adhesive material made of a fully fluorinated polymer.
  • There is also the possibility that the components of the component of ceramic and / or metallic material and / or plastic and are joined by means of an intermediate present in any geometric shape fully fluorinated polymer cohesively.
  • The shape of the fully fluorinated solid polymer is adapted to the geometric shape of the respective ceramic / metallic / plastic components to be joined and may have apertures depending on the structure.
  • The apertures in the fully fluorinated solid polymer are sized so that outer and inner edges, respectively, are recessed from the edges of the components to be joined, thereby preventing or minimizing entry into the interior of the components upon melting of the material.
  • The fully fluorinated solid polymer has comparable chemical resistance as the material of the components to be joined.
  • The component produced by the method may be a tube bundle, plate, block or annular groove heat exchanger or a micro-reactor.
  • Reference to exemplary embodiments, the invention will be described in detail.

  • In a simple design head and foot consist 2 ; 3 made of metal with an enamelled or otherwise coated surface. The blocks 4 consist for example of a technical ceramics, preferably of SiC.
  • For making the main part of the heat exchanger 1 become the individual blocks 4 stacked on top of each other, taking between each block 4 each as a fully fluorinated solid polymer, a melt-adhesive film 5 is used. The melt-adhesive foil 5 consists of a fully fluorinated polymer and has a thickness of 0.3 mm. The contour of the melt-adhesive foil 5 is adapted to the contours of the parts to be joined or the melt-adhesive film 5 points according to the channel structure of the blocks 4 Breakthroughs on. Optionally, the surfaces of the items to be joined are provided with a primer.
  • The so from the individual blocks 4 with the intermediate melt-adhesive foils 5 formed main part of the heat exchanger 1 is clamped, for example, a contact pressure of 2 N / mm 2 is applied to the items to be joined. The prepared main part of the heat exchanger 1 is in a device to a temperature above the melting temperature of the fully fluorinated polymer 5 heated and remains in this after reaching the melting temperature for a period of 2 to 30 minutes, preferably 15 min. Thereafter, the parts are cooled to room temperature. The spatial temperature gradients in the heating and in the cooling process are in the range of less than 2 degrees / mm.
