Because of gold -plated oxidation. Introduction:
gold plating is a decorative process and one of the commonly used vocabulary. Initially refers to a thin layer of gold on the surface of the utensil. Later, it was also used to compare people to a certain environment for further studies or exercise. type:
The gold plating is divided into two categories, one is plated at homogeneous materials, and the other is heterogeneous material gold plating. Gold plating gold plating refers to gold plating on the surface of gold jewelry. Its significance is to improve the brightness and color of jewelry. Heterogeneous material gold plating refers to the surface of non -golden materials for gold plating, such as silver -plated and copper gold plating.

The gold -plated product has been in case of anti -time, and the surface of the golden layer is black, instead of the golden coating on the surface of the surface, because the gold -plated coating is very thin, and the metal inside is easily destroyed on the plating on the surface. It turned out that gold only sent the product to the electroplating processing plant to re -plated first. Mo -plating plant first uses a water wave polishing machine to polish the surface of the product, removes oxidation, and then picks up. This process can be placed in the electroplating groove. The same golden light. It wipe the golden surface layer with other wiping cloth will erase the electroplating layer. It will also remove the golden color on the surface while removing the black.

The easiest way to use the phenomenon of oxidation is to wipe the toothpaste, and it will be glorious.
