Metal zipper plating is a chemical reaction, not an electrolytic reaction. Metal zipper plating chemicals are available for professional sales with the main experience. Can do out of the general colors: bronze (different brightness can be divided into ordinary green ancient, ancient sweep green, bright green ancient), gold, platinum, light gold, rose gold and other colors.
Copper is the difference between the use of poor students, the effect of chemical reaction is also different (the higher the amount of copper content of the larger expression) is more commonly used raw materials, copper is the pursuit of high brightness effect of general H90 use, such as rose gold.
Since the chemical plating is only a thin layer, and the nature of instability, so the hot spot area in the chain process (transparent protective paint) can maintain color, but also corrosion and oxidation.
Aluminum or copper zipper is not with the alkaline and acidic substances or not damp, to maintain a complete process, so as to avoid the metal gear wet oxidation, corrosion.
Metal zipper is generally linked to the plating process (linked to the coating is very thin, the hand can rub off), and then a layer of protective film, will not fade, but after the use of this protective film will wear after prolonged use, When we must look for the zipper plating process, as long as the production in strict accordance with the metal zipper, the service life will be relatively long.
