Definitions
- the present invention relates to a method of surface treatment of a metal container having at least one orifice, said method being more particularly intended for the pickling of containers made up of assembled sheets by welding, crimping, riveting, bonding, etc.
- the object of the present invention is therefore to provide a surface treatment method which does not have the drawbacks of the prior art and which makes it possible in particular to treat metal containers without generating large quantities of toxic effluents, in complete safety for operators, and with improved and high productivity.
- a first object of the present invention is constituted by a method of surface treatment of a metal container having at least one orifice, by at least one treatment solution, characterized in that it comprises the steps consisting in :
- said container in a treatment enclosure in such a way that its orifice faces downwards, said enclosure comprising a plurality of nozzles for spraying said solution under pressure and at least one receiving tank,
- the treatment solution is sprayed at a pressure below 90 bar
- the pickling solution can contain at least one acid chosen from a halogen acid, an organic acid and a mineral acid,
- the container or hollow body to be treated can be made of cast iron, steel, stainless steel, titanium, zirconium, copper, nickel, or their alloys, and preferably cast iron, steel or stainless steel, and more preferably stainless steel,
- a third object of the invention consists of a surface treatment line of a metal container having at least one orifice, comprising a device according to the invention, and further comprising a conveyor chain feeding said device with said metal containers.
- control means comprising at least one measurement probe, in particular of the temperature, of the concentration of H + ions, or of the redox potential of the treatment solution, implanted at any point of the recirculation circuit of the solution ,
- the device includes a system for suction and condensation of acid vapors.
- the method according to the invention can be applied to any metallic surface, and in particular to cast iron, steel, alloy steels, ferrous alloys, nickel and its alloys, chromium and its alloys, titanium and its alloys, zirconium and its alloys, as well as copper and its alloys.
- the present inventors have found that spraying a pickling solution at a pressure greater than 8 bar, and preferably greater than 10 bar, makes it possible to obtain pickling times divided at least by 6, compared to methods of 'immersion in tanks.
- the projection of the pickling solution makes it possible to crack the calamines and then inject the solution into its cracks. This mechanical action is associated with a chemical action by a percolation - chemical dissolution mechanism.
- the pickling solution at a pressure of less than 90 bar.
- the device according to the invention as shown in Figure 1 comprises an enclosure 1 which can be made gas and liquid tight vis-à-vis the outside of the device.
- this enclosure 1 is installed a plate (not shown) provided with a receiving tank 2 connected to a system for recovering a treatment solution.
- the enclosure 1 also includes a lower projection nozzle 3 intended for the treatment of the internal part of a metal container 4, as well as a series of nozzles 5, 5 ', 5 "in the upper part of the enclosure 1 and intended for the treatment of the external part of the container 4.
- the enclosure 1 can further comprise a system for suction and condensation of acid vapors (not shown), as well as a heating system for the enclosure 1 with automatic regulation.
- It comprises at least one receiving tank 2, but can contain as many as there are different treatment solutions, which can make it possible to collect each solution in a specific tank and therefore to facilitate its recycling and / or its recirculation in the 'pregnant.
- Means can also be provided for adding reagents to this enclosure 1, as well as sensors 6, 6 ′, 6 ′′ making it possible to monitor the good progress of the surface treatment.
- sensors 6, 6 ′, 6 “measuring the redox potential, the H + concentration, the temperature, or any other sensor which can make it possible to determine whether the solution must be treated before being used.
- a pickling solution which can be used in the process according to the invention may comprise an acid or a mixture of mineral acids comprising a halogen compound or a sulphate, orthophosphate or metaphosphate radical, or alternatively an acid or a mixture of aliphatic organic acids or cyclic, such as a peroxygenated acid such as peracetic acid, or acid Perboric.
- This solution can also include mixtures of acids of different nature, such as a mixture of halogen acid and mineral acid, for example.
- the concentration of acids is preferably between 0.1 and 7 moles per liter, and more preferably between 0.1 and 6 moles per liter, while the concentration of metals in the solution is preferably between 0 , 2 and 2 moles per liter.
- This pickling solution also comprises an oxidized compound originating from the metal constituting the container to be treated at its maximum valence.
- This compound can also be combined with the pickling solution by dissolving a synthetic salt in the solution or by the action of hydrogen peroxide, ozone or persalts.
- the composition of the solution will be adapted to the composition and to the constitution of the oxides to be eliminated.
- the temperature of the solution is preferably between 40 ° C and 80 ° C, and more particularly preferably, of the order of 60 ° C, more or less 2 ° C.
- the container Before or after spraying this pickling solution, the container can be rinsed with hot (60 ° C) or cold (15 ° C) aqueous solutions, for example. It can also be passivated by hydrogen peroxide diluted in an acid medium, or any other solution (persalts, etc.).
- hot (60 ° C) or cold (15 ° C) aqueous solutions for example. It can also be passivated by hydrogen peroxide diluted in an acid medium, or any other solution (persalts, etc.).
