There are many surface treatment methods for service station signs on the market today, but there may be many problems in the quality of service station signs surface solution. You should not have seen these production methods, and we will share them together

Photoetching

Commonly known as photolithography technology, it is the use of photographs to make corrosion-resistant film images for the maintenance of the surface of service station signs. The surface of some metal materials and plastic service station signs can be corroded by organic chemical etchants. Laminated glass and porcelain type service station signs can also use this technology to carry out surface solutions.

Chemistry is also polishing method

This method is to use the service station signs prepared for polishing in advance as the positive electrode, the non-melting metal material as the negative electrode, and then invade the secondary at the same time into the electrostatic precipitator, and form a purposefully positive electrode melting according to the DC power supply ionization reaction. Furthermore, some small raw edges on the surface of the service station signs are produced to improve the color of the service station signs to a large extent.

The principle of electroplating is to adhere a ceramic film on the surface of the front parts of service station signs by electrolytic reaction. The material of this kind of ceramic film is zinc. Since zinc has a very good oxidation resistance, zinc is generally used as raw material in the electroplating process in industrial production, mainly to avoid air oxidation of metal materials. Improve the wear resistance level of service station signs to improve the beauty of service station signs
