The method of electrolytic coloring of telescopic ladder

As far as the industrialized coloring process is concerned, it can be divided into: tin salt and tin-nickel mixed salt bath electrolytic coloring method (champagne color system); nickel salt electrolytic coloring process (champagne color system); manganese There are several categories such as salt electrolysis coloring process (golden yellow) and selenite coloring process (titanium gold).

The coloring power supply of tin salt bath liquid is a relatively simple common AC coloring power supply, which has been widely produced and applied in China and Europe. However, it is not easy to obtain a stable and uniform light-colored system in the tin salt bath. It is more reliable to choose nickel salt electrolytic coloring method to obtain light colors such as imitation stainless steel color and champagne color.

At present, the most commonly used coloring process in my country is the "Sumika" coloring process introduced from Japan, also known as the direct nickel salt coloring method.
