At present, there are many surface treatment methods for traffic hubs signage project on the market, but the quality and quality of traffic hubs signage project surface treatment are uneven. The following are the most common signs surface treatment methods you must have heard of.

The most common treatment methods are photoetching, electrolytic polishing, electroplating and so on.

traffic hubs signage project makes photoetchings

Referred to as lithography, the use of photographic means to make anti-corrosion film image, mainly used to protect the surface of the sign plate, in a series of metal and plastic sign plate surface can be treated with chemical corrosion agents, in addition to metal, glass and ceramic signs can also use this technology for surface treatment.

This method is to have a prepared sign as a positive electrode, some insoluble metal as a negative electrode, and then put the two stages in the electrolytic cell at the same time, through the direct current electroionization reaction to produce a selective anode solution, so that some subtle burr on the surface of the sign can increase the brightness of the sign to the greatest extent.

Electroplating method is the use of electrolytic reaction to attach a layer of metal film on the surface of the parts of the logo, the metal film material is zinc, so zinc has a very good oxidation resistance, plating in the industry is generally the use of zinc as a material, so as to maximize the prevention of metal oxidation, improve the wear resistance of the logo to increase the appearance of the logo.
