Description
Método para el tratamiento superficial de superficies metálicas y no metálicas.Method for surface treatment of metallic and nonmetallic surfaces.
La presente invención se refiere a un método para el tratamiento superficies para el electrochapado de superficies metálicas o no metálicas con una capa metálica, recubriéndose dicha capa metálica con una capa acrílica no corrosiva.The present invention relates to a method for the treatment of electroplating surfaces metallic or non-metallic surfaces with a metallic layer, said metallic layer being coated with an acrylic layer not corrosive
El método convencional de electrochapado de
capas metálicas sobre objetos, tales como, asas de cajones, asas
de puertas y cerraduras generalmente utiliza soluciones
concentradas de ácido para eliminar partículas extrañas y polvo de
la superficie a tratar, siendo introducido a continuación el objeto
en un tanque electrolítico a fin de electrochapar la capa metálica
deseada sobre la superficie del objeto. Posteriormente la capa
metálica se recubre con laca a modo de capa protectora. Sin
embargo, es importante resaltar que las soluciones químicas, tales
como, las soluciones concentradas de ácido, son perjudiciales para
el medio ambiente y que los equipos de tratamiento para las
soluciones químicas son costosos, lo que implica un aumento en los
gastos de producción. Además, el hecho de que únicamente los
objetos con superficie metálica puedan ser electrochapados limita
su campo de actuación. Las lacas, además, no poseen una buena
función anticorrosiva, lo cual resulta importante en determinadas
circunstancias, carecen de durabilidad y su lustro es difícil de
mantener. Habitualmente, los objetos son recubiertos con cobre,
níquel y plata, cuya función es antioxidante, aunque estos
múltiples procesos también incrementan los gastos de
fabricación.The conventional method of electroplating metal layers on objects such as drawer handles, door handles and locks generally uses concentrated acid solutions to remove foreign particles and dust from the surface to be treated, the object being then introduced into a tank electrolytic in order to electroplate the desired metal layer on the surface of the object. Later the metallic layer is covered with lacquer as a protective layer. However, it is important to note that chemical solutions, such as concentrated acid solutions, are harmful to the environment and that treatment equipment for chemical solutions is expensive, which implies an increase in production costs. In addition, the fact that only objects with a metal surface can be electroplated limits their field of action. In addition, lacquers do not have a good anti-corrosive function, which is important in certain circumstances, they lack durability and their luster is difficult to maintain. Usually, objects are coated with copper, nickel and silver, whose function is antioxidant, although these multiple processes also increase the costs of
manufacturing.
