るため、良好なメツキ製品ができない。Prepare a chemical nickel plating solution (see below for its composition) in a plating tank for these materials, heat the solution to 90-95°C, and apply N1 to the plated materials such as iron, copper, copper alloy, aluminum, etc.
- When plating with P, a nickel compound (Ni-P) precipitates on the surface of the plating tank in about 40 to 180 hours, making it impossible to produce a good plated product.

化物被膜が槽の表面に生成するからである。Therefore, in order to remove the precipitates, all the plating liquid in the liquid tank was extracted, and then cold concentrated nitric acid (concentrated nitric acid at room temperature or lower temperature) was added to the tank volume and left for about 24 hours. At present, the nitric acid is extracted, the inside of the tank is washed with water, and the tank is reused (as is well known). N in chemical nickel plating solution
This is because austenite and metal oxide films, which are extremely inert to 1-P, are formed on the surface of the tank.
しかしながら、従来の冷硝酸による方法だとメツキ槽の

うな欠点があった。However, the conventional method using cold nitric acid has a short plating tank life of 40 to 80 hours, and also has the following drawbacks.
(1) メツキ槽内のクリーニングや材質再生のため
に使用する硝酸の量が多く、費用がかかる。(1) A large amount of nitric acid is used for cleaning inside the plating tank and for regenerating the material, which is expensive.
(2)使用済の硝酸は廃棄しなければならず、そのため

(4) 多くの労力や時間を必要とする。(4) It requires a lot of effort and time.

法にも関する。Structure of the Invention The present invention provides a method of cleaning the inner surface of a steel-based tank material such as stainless steel such as SUS-304 or SUS-3i 6 constituting a plating liquid tank with hot nitric acid (preferably nitric acid at a temperature of about 40 to 50°C). ) The present invention is also characterized in that a chemical nickel plating solution bath obtained by the above manufacturing method is used. It also relates to chemical nickel plating methods.

く、すなわち確実に長時間使用できることを発見した。According to the present invention, by treating the inner surface of a tank made of a stainless steel material such as SUS-304 or 5LIS-316 with hot nitric acid (preferably at about 40 to 50°C), Ni-P is precipitated in a chemical nickel plating solution. can be effectively prevented. This hot nitric acid treatment produces a large amount of austenite and metal oxide coatings on the entire surface, resulting in approximately 200% of chemical plating.
It was discovered that there was no precipitate on the inner surface of the plating tank even after using it for 0 hours or more, that is, it could be used reliably for a long time.

膜が全面的番こ多量生成するためである。In order to quickly generate austenite that does not react with Ni-P on the surface of a tank made of stainless steel materials such as SUS-304 and SUS-316, hot nitric acid is applied to the surface of the material as if it were a liquid. I have found that it is best to inject it as if hitting it. This is because a large amount of austenite or metal oxide film is formed all over the interior of the material due to the etching action of the liquid that extends not only to the surface of the material but also to the inside of the wall thickness.
この方法だと短時間(たとえば3〜5分間)の熱硝酸の
処理でよく、また、この熱硝酸は循環再使用が何回でも
できる特長がある。This method requires hot nitric acid treatment for a short time (for example, 3 to 5 minutes), and this hot nitric acid has the advantage that it can be recycled and reused any number of times.

転が可能になったのである。With the conventional method, the material had to be treated with cold nitric acid all day and night, and this method also had the major drawback of having to treat with cold nitric acid every 4088 hours of plating operation. With the new method according to the present invention, it can be used semi-permanently with just one short treatment, making it possible to operate the plating equipment continuously.
