[ALUMINIUM NETWORK] According to the coloring process that has been industrialized nowadays, according to the different types of colored salts, it can be divided into: tin salt and tin-nickel mixed salt bath electrolytic coloring (champagne); nickel salt electrolytic coloring process ( Champagne color); manganese salt electrolytic coloring process (gold) and selenite coloring process (titanium gold) and other major categories.
Tin salt bath coloring power supply 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. Imitation of stainless steel and champagne, such as light-colored or obtained by the choice of nickel salt electrolytic coloring method is more reliable. Currently used in China is the "dwelling" method of coloring imported from Japan. It is also called the direct nickel salt coloring method (ie, we often say the single nickel salt coloring method).
Gate Valves are called "full-flow" valves; there's a direct unobstructed path for flow right through the middle of the valve. A wedge-shaped brass gate is lowered into a machined slot to close the valve. They should either be completely open or completely closed. Water flowing through a partially open gate valve wears away the metal and causes the valve to fail over time.
