Abstract

PURPOSE:To obtain a uniform satin plating, by taking out a plating solution from a plating tank in an overflowing manner, adding a satin plating forming additive to the plating solution thus taken out, and spouting said plating solution from a plurality of spouting holes in a spouting pipe positioned at the bottom surface of the plating tank. CONSTITUTION:An overflow tank 3 is attached to the plating tank 2 and the plating solution is allowed to overflow from the plating tank 2 continuously to the overflow tank 3. By controlling a valve 22, an additive that will form an organic emulsion in the plating solution is continuously or intermittently fed from a storage tank 21 into the plating solution in the overflow tank 3 and is mixed therewith by a stirrer 24. After the mixing, the plating solution is sucked by a pump 5 and is spouted via a pipe 8 from the spouting holes 9 in the pipe 10 into the plating solution in the plating tank 2.

On the other hand, a conventional method is known in which satin-like plating is performed using an additive that forms an organic emulsion in a plating solution. As such a plating method, the temperature is 40~
By adding ethylene oxide and propylene oxide compounds, which form a finely dispersed emulsion at 75°C, to the plating solution and performing the entire plating with the solution suspended by raising the solution temperature during plating, satin-like nickel is produced. A method for obtaining an electrodeposited material (Japanese Patent Publication No. 46-644), by adding a cationically active or amphoteric substance together with an organic anion to a plating solution to generate a different substance in the plating solution, a satin-like nickel or nickel-cobalt electrode is produced. Several methods have been proposed for obtaining kimono (Japanese Unexamined Patent Publication No. 5O-2093), and each method has various advantages, and the latter method in particular can produce satin cloth in various states with excellent appearance and physical properties. It has the following advantages: 1) No special cooling/heating equipment is required, and bath management is easy. However, in this satin-like plating method that uses additives that form an organic emulsion in the plating solution,
Because the additives are consumed during plating, they must be replenished at regular intervals, and each time the plating operation is stopped, the plating solution is replenished with additives, and the plating solution is stirred using a stirring rod. , mechanical stirring is required. Therefore, there is no problem when plating with a robot-type automatic machine or a manual line, but when replenishing with an elevator-type automatic machine, it is necessary to empty the hanger for several minutes and completely stop the machine.

The present invention has been developed in view of the above circumstances, and is a method for performing satin-like plating using an additive that forms an organic emulsion in a plating solution. When the plating solution is overflowed into one overflow tank and the additives are replenished into the plating solution in the plating tank, the additives are mixed with the plating solution in the overflow tank and the additives are replenished. Additives are supplied to the plating liquid in the plating tank by suctioning the plating liquid with a pump and blowing it out from a number of blow-off holes provided in the blow-off pipe placed at the bottom of the plating tank. By doing so, the additive can be replenished using an automatic replenishment method and t7. Therefore, the present invention provides an entire satin-like plating method that does not require stopping the plating operation when replenishing additives.

In the circulation path where all the plating solution is taken out from the plating tank 2 and then returned to the plating tank, is there a plating solution outlet on the lower side of the plating tank?
The plating solution is removed from the plating tank, and the additives are completely replenished during the circulation route, or the plating solution with the replenishment solution added during the circulation route is simply returned partially to a corner of the plating tank. Similarly, satin-like appearance [% unevenness]
Therefore, in the additive replenishment method described above, plating is performed while replenishing. Continuing the process would not only deteriorate the appearance of the plating, but also cause variations in the physical properties of the film. On the other hand, the plating solution is taken out from the plating tank using an overflow method, and the removed plating solution is mixed with an additive for forming a satin plating, and the entire plating solution to which the additive has been added is removed. When blowing out from the air outlet provided along the bottom of the plating tank at the bottom of the tank, and the many air holes formed in this pipe, it is possible to continue plating work while adopting this replenishment method. It has been discovered that uniform plating can be performed with almost no effect on the satin plating appearance or physical properties of the plating.
