Definitions
- the present invention relates to a coating process.
- it relates to a method for coating the fluid media contacting surfaces of turbomachinery.
- turbomachines including, for example, components of power plants, build up in the course of their service life soiling and deposits that affect their operation. Also results as a result of cleaning these components z. B. with water increased corrosion. Oil, dust or soot that occurs in the vicinity of the components can be the cause of such problems.
- components of power plants are the compressor of gas turbines and air-cooled generators which become contaminated as a result of impurities in the air being sucked by the compressor or the generator cooling.
- the compressor stator, the compressor rotor and in particular the compressor blades must be cleaned at regular intervals to ensure proper operation of the turbine.
- the compressor blades are cleaned during operation of the turbine by injecting finely divided water into the compressor inlet ("online washing").
- the object of the present invention is to overcome at least one of the disadvantages described in the prior art.
- the present invention has the object to provide a method for coating the fluid media in contact surfaces of turbomachinery available, so that the resulting surfaces are protected against corrosion, are easy to clean and do not contain toxic chromium-containing compounds.
- the object is achieved according to the invention by a method for coating the fluid media in contact surfaces of turbomachinery, wherein contacting the outer surface of fluid media in contact parts of turbomachines with a coating comprising an inorganic-organic hybrid polymer, wherein the coating is produced by reacting monomers according to the following formula (I) and subsequently hardening to form the coating:
- M is Al, Si, Ti and / or Zr
- R is H or a branched or unbranched alkyl group having 1 to 9 C atoms
- the fluid media which come into contact with the surfaces of the turbomachines are selected from the group comprising gases, liquids and / or aerosols, preferably air and / or water.
- the media may be at room temperature, below room temperature or above room temperature.
- air may be at room temperature and an aerosol such as a fuel / air mixture may be at an elevated temperature.
- turbomachines in the context of the invention refers to fluid energy machines that operate continuously, so build a static pressure difference between inlet and outlet. They can be selected from the group comprising propellers, repellers, centrifugal pumps, fans, water turbines, compressors, steam turbines and / or gas turbines.
- propellers and repellers design caseless turbomachines which take up mechanical work and release it in the form of flow energy to the surrounding medium (propeller) or conversely take energy from the driving fluid and make it available in the form of mechanical rotation and torque ( Repeller).
- Centrifugal pumps in the context of the present invention designate pumps in which a fluid medium is replaced by mechanical fluid.
- Hydro turbines refer to turbines that harness hydropower. Here, potential and / or kinetic energy is converted into mechanical work or by means of a generator located on the turbine axis directly into electricity.
- fluid compressors which are used for compressing gases
- compressors also referred to as compressors.
- Steam turbines or gas turbines are to be understood as turbine types which comprise a rotating shaft which is equipped with turbine blades. The turbine blades are surrounded by water vapor or hot gases such as combustion gases.
- Inorganic-organic hybrid polymers are materials which have an inorganic network with organic components and optionally an additional organic network.
- Inorganic-organic hybrid polymers are derived from organically modified metal alkoxides. These metal alkoxides are referred to in the context of this invention as monomers.
- the inorganic network is formed in a two-stage sol-gel process.
- the metal alkoxides are partially or completely hydrolyzed with elimination of the corresponding alcohols.
- the metal hydroxides condense with elimination of water to form the oxygen-bridged inorganic network.
- Examples of branched or unbranched alkyl groups having 1 to 9 C atoms are selected from the group comprising methyl, ethyl, propyl, isopropyl, ⁇ -butyl, isobutyl and / or sec-butyl.
- Preferred are such alkyl groups as methyl or Ethyl which gives low boiling point alcohols after hydrolysis of the metal alkoxides.
- the organic groups X and Y considerably influence the properties of the coating.
- hydrophobic organic groups can lower the surface energy of the coating.
- Fluorinated groups are particularly effective in reducing surface energy.
- the coating becomes hydrophobic and / or oleophobic, ie water-repellent or oil-repellent.
- the surface coating exhibits so-called "easy-to-clean" properties: water and organic liquids peel off easily and the low adhesion forces facilitate and accelerate the mechanical removal of dust or dust
- Such hydrophobicity or oleophobicity can be expressed by the contact angle of the liquid in question.
- the angle of contact is the angle formed by the drop of liquid on the surface of a solid to this surface. The larger the contact angle, the lower the interaction of the liquid with the surface.
- the contact angles of the surfaces coated by the process according to the invention against water can be in a range of> 80 ° to ⁇ 130 °, preferably> 90 ° to ⁇ 130 °, more preferably> 98 ° to ⁇ 130 °.
- the contact angles of the surfaces coated by the process according to the invention against CH 2 I 2 can be in a range from> 45 ° to ⁇ 90 °, preferably> 50 ° to ⁇ 90 °, even more preferably> 60 ° to ⁇ 90 °.
- the contact angle with respect to water is about 63 ° and, with respect to CH 2 I 2, about 38 °.
- Non-reactive aryl, alkyl, fluoroalkyl, fluoroaryl, perfluoroalkyl and / or Perfluoroaryl groups are selected from the group comprising phenyl, naphthyl, methyl, ethyl, propyl, isopropyl, ⁇ -butyl, isobutyl and / or sec-butyl, difluoromethyl, trifluoromethyl, pentafluoroethyl, CeFi 3 , tridecafluoro-1, 1, 2, 2-tetrahydrooctyl, fluorophenyl and / or pentafluorophenyl.
- Reactive organic groups can be epoxy, acrylate, vinyl, allyl, isocyanate, amine and / or hydroxyl groups. These groups can also have hydrophobic properties after the organic radical carrying them. Furthermore, they may be capable of reacting with other reactive groups and contribute to cross-linking of the hybrid polymer. For example, such an organic network results in improved elasticity of the hybrid polymer.
- the curing of the coating can be effected thermally or photochemically. On the one hand, it serves the purpose of completing the condensation of the metal hydroxides to form an inorganic network. On the other hand, it is also possible for the above-mentioned reactive organic groups to be crosslinked with one another.
- the coating additionally comprises inorganic microparticles and / or nanoparticles selected from the group comprising magnesium, zinc, iron, nickel, palladium, platinum, cobalt, rhodium, iridium, titanium dioxide, zirconium dioxide, cerium oxide, Vanadium pentoxide, alumina, silicon carbide and / or silicon dioxide on.
- Microparticles in the sense of this invention refers to particles which have dimensions of ⁇ 10 ⁇ m in at least one dimension; Nanoparticles in the sense of this invention refers to particles which have dimensions of ⁇ 10 nm in at least one dimension.
- Typical functions provided by such particles are additional hydrophobicity, scratch resistance, catalytic action (thermal or by UV light) and / or corrosion inhibition. It is particularly advantageous if the Particles at the operating temperatures of the coated device act as an oxidation catalyst to destroy adhering dirt.
- the particles may additionally be surface-coated with substances selected from the group comprising silicon dioxide, silicone oils, silanes, aluminum hydroxide, stearic acid and / or aluminum oxide.
- the particles can also be added to the sol of the coating to be applied in the form of colloidal solutions. As a result, a good distribution of the particles is possible in a simple way.
- the method according to the invention comprises the following steps:
- the hydrolysis can be carried out in pure water or in the presence of other solvents such as alcohols.
- An advantage of using a solvent mixture is that monomers with a lower solubility in water can also be processed.
- the hydrolysis can be carried out in a multi-phase system of water and a water-immiscible solvent. This is useful if the monomer is very poorly soluble in water.
- the hydrolysis can be carried out in the presence of an acid, such as hydrochloric acid. This increases the reaction rate of the hydrolysis.
- the temperature of the reaction may be below room temperature, at room temperature or above half the room temperature.
- reaction time of the hydrolysis is chosen such that the most complete possible hydrolysis, but if possible no premature crosslinking is achieved. Preferably, this reaction time is 24 hours per batch.
- the next step is coating the substrate with the reaction mixture from the hydrolysis reaction.
- An advantage of the coating method according to the invention is that the coating can be applied without further protective measures against oxygen or moisture. This allows common techniques to be used. When spraying, for example, it is possible to resort to spray robots which can uniformly coat complex shaped bodies. The immersion of the object to be coated represents a very simple procedure. As well as the application by rolling or wiping, it is possible to coat existing systems on site with or advantageously without disassembly of the items.
- the thermal curing may advantageously at a temperature of> 25 0 C to ⁇ 500 0 C, preferably> 100 0 C to ⁇ 400 0 C, more preferably> 150 0 C to ⁇ 300 0 C, most preferably of> 170 0 C. be carried out to ⁇ 250 0 C.
- a thermal hardening processing above 300 0 C generally leads to decomposition of the organic components and to form a high temperature resistant coating. This coating then shows a glassy behavior. Curing of the coating by means of UV or visible light may be advantageous where components are to be subsequently coated and disassembly of the equipment containing these components does not appear expedient.
- the UV light may, for example, have a wavelength of> 250 nm to ⁇ 370 nm. Furthermore, the spectrum of the UV light can have an intensity maximum at 360 nm. UV lamps that emit light of such wavelength are readily available commercially and relatively inexpensive to use.
- the sol used in the process according to the invention may comprise methyltriethoxysilane in a proportion of> 50% by weight to ⁇ 75% by weight. Such high proportions by weight make it possible to introduce a high silicon content into the coating.
- the sol employed in the process according to the invention may comprise 3-glycidyloxypropyltriethoxysilane in a proportion of> 15% by weight to ⁇ 30% by weight. Below this range, the post-crosslinking via the epoxide group no longer contributes significantly to improved material properties. Above this range, no significant increase in material properties compared to the cost of the component is expected.
- the sol used in the process according to the invention may comprise phenyltriethoxysilane in a proportion of> 5% by weight to ⁇ 15% by weight. Below this range, the phenyl group no longer contributes significantly to the desired hydrophobicity. Above this range, a deterioration in mechanical stability and no significant improvement in the hydrophobicity of the coating is expected.
- the sol used in the process according to the invention Tridecafluoro-1, 1, 2, 2-tetrahydrooctyltriethoxysilane in a proportion of> 0.5 wt .-% to ⁇ 3 wt .-% include. Below this range, the fluoroalkyl group no longer contributes significantly to the desired hydrophobicity. Above this There is no significant increase in hydrophobicity and oleophobicity compared to the cost of the component.
- the sol employed in the process according to the invention may comprise 1-methoxy-2-propanol-2 in a proportion of> 5% by weight to ⁇ 15% by weight.
- This medium-volatile, water-miscible solvent has the advantage of good biodegradability.
- Another object of the invention relates to a coating, which can be produced by the method according to the invention.
- the cured coating may have a silicon content of ⁇ 1 wt .-% to ⁇ 50 wt .-%, preferably> 5 wt .-% to ⁇ 30 wt .-%, particularly preferably> 10 wt .-% to ⁇ 20 wt .-%, most preferably from> 13 wt .-% to ⁇ 17 wt .-% have.
- the cured coating may have a contact angle to water of> 80 ° to ⁇ 130 °, preferably> 90 ° to ⁇ 130 °, even more preferably> 98 ° to ⁇ 130 °.
- the cured coating may have a contact angle against CH 2 I 2 of> 45 ° to ⁇ 90 °, preferably> 50 ° to ⁇ 90 °, more preferably> 60 ° to ⁇ 90 °.
- the silicon content is calculated as the weight fraction of the silicon atoms contained in the coating, based on the total weight of the coating.
- the properties of the coated surface are advantageously influenced by the coating according to the invention. This reduces the surface energy, which prevents dirt from easily adhering and removing with less effort. Furthermore, the surface according to the invention and the workpiece as a whole are protected against corrosion. Thus, use in aggressive environments such as salty water is possible.
