Definitions
- the present invention relates to a new process for electrodeposition of electrically conductive, three-dimensionally shaped substrates in a continuous system.
- the present invention relates to a new continuous system for carrying out the new process for electrocoating electrically conductive, three-dimensionally shaped substrates.
- the present invention was based on the object of providing a new continuous system with which a method for electrodeposition of electrically conductive, three-dimensionally shaped substrates can be carried out, in which the substrates are rotated during immersion and immersion, so that they can be used particularly well later less or no sediment at all on the visible outer sides, but the foam formed when the substrates are immersed in critical areas of the substrates no longer leads to coating defects and considerable losses in quality in terms of corrosion protection.
- Exchanging area rotated back to the original position about a horizontal axis of rotation perpendicular to the transport direction and 11.5 are passed on for further processing after the surface has emerged,
- the new process for electrodeposition of electrically conductive, three-dimensionally shaped substrates in a continuous system is referred to as the “process according to the invention”.
- an electrodeposition basin containing the electrodeposition paint - an overflow basin containing the electrodeposition lacquer, at least one circulating pump for sucking off the electrodeposition lacquer on the bottom of the basin of the overflow basin, at least one circulating pump for sucking off the electrodeposition lacquer on the basin floor at the end of the electrodeposition basin opposite the overflow basin for returning at least two flood pipes of the electrodeposition paint sucked off via the circulating pumps into the electrodeposition paint basin at the bottom of the basin in such a way that a directed basin flow is formed in the longitudinal direction in the electrodeposition paint pool, wherein the pool flow in the area of the pool floor is opposite to the pool flow in the area of the bath surface, at least one conveyor with devices for transporting the substrates to the electrocoating tank, rotating and immersing the substrates in the electrocoating tank at one end in the immersion area, transporting the substrates through the electrocoating tank in Longitudinal direction and rotation and immersion of the substrates from the electrocoating tank at its other end in the immersion area, an immersion area
- system according to the invention The new continuous system for carrying out the method according to the invention is referred to below as the "system according to the invention”.
- the substrates coated with the aid of the method according to the invention no longer had any or only very few coating defects caused by sediments in the later clearly visible outer sides. Moreover they no longer had foam coating problems in critical areas such as cavities. It was particularly surprising that these advantages could be achieved in a comparatively simple way by modifying existing continuous systems.
- the substrates coated with the aid of the method according to the invention were clearly superior to the substrates coated in the conventional manner in terms of overall appearance (appearance) and corrosion protection.
- These particular advantages of the method according to the invention emerged in a particularly advantageous manner in vehicle bodies, in particular motor vehicle bodies, because particularly high demands are made on the appearance of the visible outer sides and on corrosion protection in the area of the cavities and the underbody, particularly in the case of motor vehicles, in particular passenger cars.
- the system according to the invention and the method according to the invention serve to coat electrically conductive, three-dimensionally shaped substrates, in particular vehicle bodies, radiators and housings of washing machines,
- Electrodeposition paint can be deposited anodically (ATL) or cathodically (KTL), in particular cathodically.
- ATL anodically
- KTL cathodically
- This coating process is known as electrodeposition and the system as electrodeposition (cf. Römpp Online, 2002, "Electrodeposition”, electrodeposition paints, and “electrodeposition” as well as the BASF Handbook painting Technology, BASF Coatings AG, 2002, Vincentz Verlag, Hanover, pages 497 to 520).
- the system according to the invention is a continuous system, i. that is, it serves to coat substrates that are continuously fed to the system according to the invention and continuously removed from it.
- the system according to the invention comprises the following essential system elements:
- Electrodeposition basin at least two, preferably at least three, particularly preferably at least four, very particularly preferably at least five and in particular at least six flood pipes for returning the electrodeposition lacquer sucked off via the circulating pumps into the electrodeposition lacquer basin on its basin floor in such a way that in the electrodeposition lacquer basin in
- a directed pool flow is formed in the longitudinal direction, the pool flow in the area of the pool floor being opposite to the pool flow in the area of the bath surface, d. that is, the pool flow is set up to be circulating; at least one, in particular one, conveyor with devices for transporting the substrates to the electrocoating tank, rotating and immersing the substrates in the electrocoating tank at one end in the immersion area, transporting the substrates through the
- Electrocoating basin in the longitudinal direction and rotating and immersing the substrates from the electrocoating basin at its other end in the immersion area as described, for example, in patent applications DE 196 41 048 A1, EP 1 170 063 A1, WO 98/15359 A1, WO 01/17691 A 1, the European patent
- system according to the invention can contain customary and known further system elements that are necessary for its operation, such as at least one power supply, electronic, mechanical and pneumatic measuring and control devices, electric motors, pumps,
- Overflow devices heat exchangers, devices for the supply of electrocoat, electrocoat components and neutralizing agents, ultrafiltration systems, filters, anolyte circuits for the cathodically depositable electrocoat (KTL) and rinsing zones.
- Electro-dipping system electro-dipping paints ", and” electro-dipping paints "as well as the BASF manual coating technology, BASF Coatings AG, 2002, Vincentz Verlag, Hanover, pages 497 to 520.
- the directed pool flow in the electrocoating tank is set up to be circulating in such a way that it is opposite to the transport direction of the substrates in the area of the bath surface. This is preferably accomplished by returning the electro-dip lacquer sucked off via the circulation pumps via the flood pipes into the electro-dip lacquer bath against the transport direction of the substrates on the pool floor.
- the system according to the invention is used to carry out the method according to the invention.
- the substrates are switched as a cathode or anode, in particular as a cathode, and are fed with the aid of the conveying device or conveying devices over the overflow basin to the immersion area of the electrocoating tank, when immersed in the electrocoating tank around a horizontal axis of rotation perpendicular to the direction of transport in one Angles of> 100 °, in particular at an angle of about 180 ° or 180 °, rotated to the original position, transported and coated in the new orientation through the electrocoating tank, at
- Diving out of the electrocoating tank in the dipping area is rotated back to its original position about a horizontal axis of rotation perpendicular to the direction of transport and, after dipping, fed to further processing.
- the electro-dip lacquer sucked off via the circulation pumps is returned via the flood pipes into the pool floor of the electro-dip lacquer pool in such a way that a directional pool flow occurs and is maintained, which counteracts the transport direction and the area of the bathroom surface in the area of the pool floor flows in the transport direction of the substrates.
- the suctioned-off electrocoat is filtered, in particular ultrafiltered, before it is returned to the electrocoat tank.
- the substrates are rotated in the transport direction. They can be aligned transversely to the axis of rotation or along the axis of rotation. It is also advantageous for the method according to the invention if the substrates are moved during transport through the electrocoating tank, in particular rocked in the transport direction or transversely thereto and / or raised and lowered perpendicularly to the transport direction.
- Uncoated vehicle bodies (2) were detachably connected to the conveyor (1.11) in the usual and known manner (see, for example, German patent application DE 196 41 048 A1).
- the conveyor device (1.11) contained conventional and known devices for transporting the vehicle bodies (2) over the overflow basin (1.2) to the electrocoat tank (1.1), devices for rotating and immersing the substrates (2) in the electrocoat tank (1.1) in the immersion area ( 1.12), devices for transporting the vehicle bodies (2) through the electrodeposition basin (1.1) in the longitudinal direction and devices for rotating and immersing the vehicle bodies (2) on the overflow basin (1.2) opposite the end of the electrodeposition basin (1.1) in the replacement area (1.13).
- the vehicle bodies (2) were switched as cathodes and, with the aid of the conveyor (1.11), when immersed, they were rotated and immersed at an angle of 180 ° about a horizontal axis of rotation perpendicular to the transport direction, and were transported through the electrocoating tank (1.1), in which they were carried out with a conventional and known KTL coated, and coated again dipped and rotated back to the transport direction, horizontal axis of rotation in the original position. After the dipping, they were fed with the aid of the conveying device (1.11) for further processing, in particular the drying and the thermal hardening of the cathodically deposited electrodeposition coating, which resulted in the electrodeposited vehicle bodies (2).
- the electro-dipping paint was applied with a circulation pump (1.3) on the pool floor (1.4) of the overflow basin (1.2) and with a circulation pump (1.5) on the pool floor (1.6) at the end (1.7) of the electro-dipping pool opposite the overflow pool (1.2) (1.1 ) suction filtered and filtered (1.14).
- the filtered electrocoat was returned via flood pipes (1.8) to the electrocoat tank (1.1) on the pool floor (1.6), so that a directional pool flow (1.9) was created and maintained in the longitudinal direction.
- the pool flow (1.9) in the area of the pool floor (1.6) was opposite to the pool flow (1.9) in the area of the bath surface (1.10).
- the outlet openings of the flood pipes (1.8) were oriented so that the directional pool flow (1.9) flowed in the area of the pool floor (1.6) in the transport direction of and in the area of the bath surface (1.10) against the transport direction of the vehicle bodies (2).
- the electro-painted vehicle bodies (2) had none trapped in the underbody area and in the cavities Foam and / or hydrogen caused paint defects more.
- the corrosion protection effect of the electrocoating was therefore excellent.
