Definitions
- the invention is in the field of corrosion protection surface treatment of metal strips. It specifically affects the order of so-called no-rinse products, that is, products that dry up immediately after application without an intermediate rinse with water. This means that all non-volatile components of the treatment solution used as well as the Reaction products with the metal surface remain on the metal.
- An advantage This technique consists in the fact that there is no product-laden flushing water is incurred, which must be disposed of at great expense.
- the Treatment solutions over rollers with a hard surface on the Metal strips applied which are referred to as chemcoaters or roll coaters.
- An alternative to this is the so-called spray / dip squeeze technology, at which briefly covers the surface by spraying or immersing it treatment solution to be applied is brought into contact immediately afterwards squeezed the treatment solution by means of rollers and then is dried.
- a disadvantage of the chemcoater is the high investment and operating costs.
- a disadvantage of the spray / dip squeeze process is one of the running time of the Squeeze roller dependent wet film thickness, in addition when changing width in different film runs are obtained in the peripheral areas. The Coating of the tape becomes uneven. Since the wet film continues is very thin after squeezing (usually thinner than 2 ⁇ m) slight changes in the wet film thickness very much in the layer coverage achieved noticeable.
- the invention has for its object an improved application system for To provide no-rinse products that meet the above Does not have disadvantages.
- the invention relates to a method for the chemical treatment of Metal strips, taking a treatment liquid with an application roller one or both sides on the surface of the metal strips and without Intermediate rinse dries, characterized in that as Applicator roller uses a fleece roller.
- Fleece rollers referred to as soft rolls in the Anglo-Saxon language area currently used in the strip industry as squeeze rollers.
- the surface consist of a soft pad, usually made of chemical-resistant random fibers. Examples are polyamide (nylon) fibers or polypropylene fibers. Generally all fibers be used, the sufficient volume and a have sufficient resistance to strongly acidic or alkaline solutions. In the process according to the invention, these rolls can run in opposite directions or turn with the metal band.
- the gap between the fleece rollers is preferably adjusted as a function of the sheet thickness so that the treatment liquid is applied to the surface of the metal strips with a wet film thickness in the range from 1 to 10 ⁇ m. This is the case, for example, with a gap width between approximately 0.3 and approximately 0.8 mm.
- the nip is preferably set such that a wet film thickness in the range from 2 to 6 ⁇ m (corresponding to ml / m 2 ) is set on the surface of the metal strips.
- Treatment solutions are according to the inventive method can be applied, which are suitable for no-rinse processes.
- these are Treatment fluids either acidic (pH between 0 and 7) or alkaline (pH between 7 and 14).
- the composition of the Treatment solutions are usually chosen so that a chemical reaction with the metal surface.
- Such treatment solutions are large Number known in the prior art. Examples include:
- Phosphating solutions acidic solutions containing phosphoric acid, a crystalline or amorphous metal phosphate layer on the metal surface produce. These solutions usually contain zinc ions, often as cations together with manganese and / or nickel ions.
- Chromating solutions acidic solutions, the Cr (VI) ions and often contain additional Cr (III) ions.
- Acidic or alkaline passivation solutions aqueous solutions, as a rule Transition metal ions contain and which after drying a corrosion protective Generate an amorphous (mixed) oxide layer.
- Treatment solutions based on complex fluorides usually acidic adjusted solutions of, for example, hexafluorozirconic acid, hexafluorotitanic acid, Hexafluorosilicic acid and its salts.
- Solutions or dispersions of organic film formers for example of Polyacrylates.
- the solution can be in addition to the film formers inorganic reactive components such as complex fluorides contain. This creates an inorganic / organic-polymer mixed layer generated.
- Such treatment solutions are currently used to treat different Substrates used in conventional application processes. You are on the way treating metal surface set and for example for the treatment of Steel, galvanized or alloy galvanized steel, of alloy aluminum Steel as well as for the treatment of aluminum and its alloys. Accordingly, the inventive method using such Treatment fluids for the treatment of tapes from the above Materials are used.
- the treatment solution can be applied to the surface of the surface in different ways Fleece roller can be applied. For example, it is possible to spray them on spray on the surface of the fleece roller. Alternatively, it can be over Scoop rollers from a storage container onto the surface of the fleece roller be transmitted.
- treatment liquid over the Interior of the fleece roller is applied to the surface of the fleece roller.
- the wall of the fleece roller is permeable to liquids can be executed.
- Treatment liquid fed into the interior of the fleece roller, for example, by a hollow roller shaft, can therefore by Get holes in the wall of the roller on its surface.
- the treatment solution is preferably at a temperature in the range of about 15 to about 40 ° C, in particular in the range between 20 and 30 ° C on the Metal bands applied. Then the metal strips are without Intermediate rinse dried. The time between the order of the Treatment liquid due to the fleece roller and the start of drying shorter than 1 second and no longer than 15 seconds.
- the drying itself can be done, for example, in a forced air oven, as is the case with conventional No-rinse procedure is the case.
- the fleece roller Rinse off any remaining treatment liquid For example by spraying with water.
- the fleece roller designed so that the Treatment liquid is supplied to the surface through its interior the rinsing is preferably also carried out over the interior of the fleece roller by.
- the inventive method has the advantage that even with changing Spreads a uniform application of the treatment liquid over the entire bandwidth is made possible. This avoids that different Areas of the tapes are coated to different degrees.
