Interpret the characteristics of the nickel plating sign making nickel plating is one of common electroplating technology in sign making: general nickel plating technology, silver badge
is to use less silver plating process.
Due to the effect of nickel plating is very close to the effect of silver plating, and easy to control the cost, so the industry is commonly called nickel plated silver.
Nickel plating brands appearance with silver plate appearance is very similar, both present bright silver.
The characteristics of the nickel is a bigger change, after plating color won't happen and the properties of the silver will be easily oxidized grey and black.
Silver surface rendering and popular in the folk, for example, a kind of appearance of silver grey, not silver effect.
Is because the plating nickel has good not disorderly and good appearance, so has been widely applied to many signs produced products.
Sign products can use nickel plating processing of materials, such as: copper, iron, aluminum, zinc alloy, ABS plastic, etc. Can be nickel plating processing.
Let's learn about the plating nickel plate production features: 1.
Nickel plating layer in not promiscuous sexual high in the air, because the metal nickel has a strong ability of passivation, the surface can be quickly born a very thin layer of passivation film, can withstand certain acid, alkali and atmosphere.
Plating nickel crystal is very small, and it has excellent polishing function.
The polished nickel plating mirror glossy appearance, can be obtained at the same time in the atmosphere can maintain its gloss for a long time.
Nickel plating hardness is higher, can progress products surface wearability, commonly used in the printing industry medium hardness on the surface of the layer to the progress of lead plating.
Because metal nickel with high chemical not disorderly, some chemical equipment commonly used thicker coating town, also in order to prevent the erosion is medium.
Nickel plating of application is very wide, can be used as protective decorative coating, on steel, zinc die casting, copper, aluminum alloy and plastic surface decoration, protect the substrate material from erosion or light decoration effect.
Is also commonly used in double deck plating products in the middle of the coating, make the product surface more smooth and luster.
For secondary electroplating a layer of thin chromium, or gold plated layer, make better corrosion resistance of nickel plating signs, look more beautiful.
Nickel plating technology has a lot of excellent function, because it was second only to the electric galvanized and second, the consumption account for about 10% of the total nickel production.
The sign is also in a variety of electroplating production, adopt the most one kind of metal coating.
