Abstract
El procedimiento de niquelar por vía química de modo continuo un cuerpo sólido de material catalítico, que comprende hacer un baño acuoso de niquelado químico del tipo de catión de níquel y anión de hipofosfito y que tiene una composición inicial y un ph predeterminados, poner en contacto dicho cuerpo con dicho baño durante un intervalo de tiempo con el fin de efectuar la reducción de los cationes de níquel a níquel metálico y la deposición del mismo sobre la superficie de dicho cuerpo junto con la oxidación con mitante de aniones de hipofosfito a aniones de fosfito y dando como resultado el empobrecimiento o la tendencia al empobrecimiento de cationes de níquel y aniones de hipofosfito en dicho baño y la disminución correspondiente o la tendencia a la reducción de su pH, caracterizandose dicho procedimiento por la adición a dicho baño durante dicho intervalo de tiempo de una cantidad controlada de reactivo alcalinizante suficiente en esencia para restaurar dicho pH inicial del mismo, añadir a dicho baño durante dicho intervalo de tiempo una cantidad controlada de cationes de níquel relacionada sustancialmente en una primera proporción fija con la cantidad añadida de reactivo alcalinizador, y añadir a dicho baño durante dicho intervalo de tiempo una cantidad controlada de aniones de hipofosfito relacionada sustancialmente en una segunda proporción fija con la cantidad añadida de cationes de níquel restaurando dichas adiciones de cationes de níquel y aniones de hipofosfito a dicho baño sustancialmente dicha composición inicial del mismo.The method of continuously chemically nickel plating a solid body of catalytic material, comprising making an aqueous chemical nickel plating bath of the nickel cation and hypophosphite anion type and having a predetermined initial composition and pH, contacting said body with said bath for a time interval in order to effect the reduction of the nickel cations to metallic nickel and the deposition thereof on the surface of said body together with the oxidation with hypophosphite anions mitigating to phosphite anions and resulting in the depletion or tendency to depletion of nickel cations and hypophosphite anions in said bath and a corresponding decrease or tendency to decrease in their pH, said process being characterized by the addition to said bath during said time interval of a controlled amount of alkalinizing reagent essentially sufficient to restore said initial pH thereof, adding to said bath during said time interval a controlled amount of nickel cations substantially related in a first fixed proportion to the added amount of alkalizing reagent, and adding to said bath during said time interval a controlled amount of hypophosphite anions substantially related in a second fixed ratio to the added amount of nickel cations said additions of nickel cations and hypophosphite anions to said bath substantially restoring said initial composition thereof.
