Description
Procedimiento de tratamiento de superficie ecológico de un contenedor metálico, asociando una acción química y una acción mecánica.Surface treatment procedure ecological of a metallic container, associating a chemical action and a mechanical action
La presente invención consiste en un procedimiento de tratamiento de superficie de un contenedor metálico que presenta al menos un orificio, el dicho procedimiento está en particular destinado al decapado de los contenedores conformados por planchas metálicas ensambladas por soldadura, engaste, remachado, pegado, etc...The present invention consists of a surface treatment procedure of a metal container which has at least one hole, said procedure is in particular intended for pickling containers formed by metal plates assembled by welding, crimping, riveting, stuck, etc ...
Tales contenedores son, por ejemplo, toneles, cisternas fijas o movibles, silos de almacenamiento, depósitos, balones para el calentamiento del agua sanitaria, y de manera general, el conjunto de cuerpos huecos. El orificio al que se hace referencia puede, por ejemplo, destinarse a recibir tuberías, un sistema de llenado, de calentamiento o de evacuación. A la salida de su última etapa de fabricación, generalmente es necesario proceder a un tratamiento de su superficie interna y externa, con el fin de suprimir la capa de oxidación que puede alcanzar varias decenas de micrómetros de espesor. Cuando el contenedor está ensamblado por soldadura, la zona más afectada por esta contaminación es el cordón de soldadura.Such containers are, for example, barrels, fixed or movable tanks, storage silos, tanks, balloons for heating sanitary water, and so general, the set of hollow bodies. The hole to which it is made reference can, for example, be used to receive pipes, a filling, heating or evacuation system. At the exit of its last manufacturing stage, it is generally necessary to proceed to a treatment of its internal and external surface, in order to suppress the oxidation layer that can reach several tens of micrometers thick. When the container is assembled by welding, the area most affected by this contamination is the cord Welding
Con el fin de obtener un estado de superficie compatible con las normas de acabado del producto, es pues necesario decapar, desengrasar, pasivar o proceder a un abrillantado de su superficie, lo que se hace habitualmente con ayuda de soluciones por inmersión en tinas de madera que contienen el reactivo de tratamiento que comprende ácidos.In order to obtain a surface state compatible with the product finishing standards, it is therefore necessary behead, degrease, passivate or polish your surface, which is usually done with the help of solutions by immersion in wooden tubs containing the reagent of Acid treatment.
Para contenedores cuyo volumen sobrepasa los diez litros, tales como balones de agua caliente, se puede también pulverizar el ácido con ayuda de una lanza. En este caso, el ácido se pulveriza en frío para evitar la intoxicación del operador con vapores.For containers whose volume exceeds ten liters, such as hot water balloons, you can also spray the acid with the help of a spear. In this case, the acid it is sprayed cold to avoid operator poisoning with Vapors
Estos procedimientos acumulan diferentes inconvenientes, ya que al mismo tiempo que son peligrosos en su realización, generan fuertes cantidades de efluentes tóxicos que hay que eliminar y son además poco eficaces, pues la velocidad de decapado sigue siendo lenta.These procedures accumulate different inconveniences, since at the same time they are dangerous in their realization, generate large amounts of toxic effluents that are to eliminate and are also inefficient, because the speed of pickling is still slow.
Así, el procedimiento más conocido es el procedimiento fluonítrico que presenta graves inconvenientes, ya que implica el desprendimiento de vapores nitrosos. Estos vapores provocan una fuerte contaminación atmosférica y acuosa, y hacen particularmente peligrosas las condiciones de trabajo de los operadores.Thus, the best known procedure is the Fluonitic procedure that presents serious drawbacks, since It involves the release of nitrous vapors. These vapors they cause a strong air and water pollution, and make particularly dangerous working conditions of operators
Igualmente es posible mejorar el estado de superficie por procedimientos de abrasión tales como el molido o el cepillado. Tales procedimientos presentan sin embargo una productividad muy débil, y un precio de coste elevado.It is also possible to improve the state of surface by abrasion procedures such as grinding or brushed. Such procedures however have a Very weak productivity, and a high cost price.
Se ha propuesto, en EP 766 751 decapar los elementos metálicos tales como hilos en bobinas sometiéndolos a una pulverización de ácido en una atmósfera confinada como la de un túnel de decapado, en el interior del cual se introducen regularmente un gas que contiene oxígeno, con el fin de regenerar la solución de decapado que pierde con bastante rapidez su eficacia. Este procedimiento permite multiplicar la cinética global de decapado por un factor de 2,5 en el ejemplo más favorable. Sin embargo, este procedimiento aún tiene una productividad insuficiente y no permite controlar el problema de los vapores tóxicos generados. Además, la operación bajo túnel es específica del hilo.It has been proposed, in EP 766 751 to decapitate metal elements such as threads in coils by subjecting them to a acid spraying in a confined atmosphere like that of a pickling tunnel, inside of which they are introduced regularly an oxygen-containing gas, in order to regenerate the pickling solution that loses its effectiveness quite quickly. This procedure allows to multiply the global kinetics of pickling by a factor of 2.5 in the most favorable example. Without However, this procedure still has insufficient productivity. and it does not allow to control the problem of the toxic vapors generated. In addition, the tunnel operation is thread specific.
