A motorcycle is usually composed of thousands of large and small parts, electroplated parts are one of the important components. Motorcycle electroplating parts can be divided into metal plating parts and plastic plating parts according to the plating base material, such as handlebars, fenders, rims, exhaust pipes, etc., belong to metal plating base parts; The scooter shell, instrument, trademark and model logo belong to plastic plated base parts. If the motorcycle plating is intact, the vehicle will look brilliant. On the contrary, if the plating has rust, scratches, and dents, the vehicle will appear ugly, and further affect the rider's riding image. Like some luxury large displacement imported motorcycles, such as trademarks, exhaust pipe rust, the car will be very troublesome (because these parts are very difficult to buy).

(1) Classification and characteristics of electroplating

The classification and characteristics of electroplating are mainly: electroplating can be divided into three categories according to the use of functions: protective, decorative and functional.

1, protective coating: As the name suggests, this coating is used to prevent the corrosion of products and parts, in the motorcycle production process commonly used galvanized layer to protect the main parts of steel.

2, protective - decorative coating: This coating is the most widely used in the motorcycle production process, the processing process is more complex than the protective coating, at least two layers of plating, and some more. Such as motorcycle fender, rim, corner handlebars, exhaust pipe, etc.; In addition to good appearance, this coating can also play a role in preventing the main parts from rusting.

3, functional coating: This coating is usually applied to the friction surface of shaft parts, engine cylinders and piston rings, generally by chromium plating method to increase the wear resistance of the main parts.

4, other coating: When producing tires, in order to increase the adhesion between steel wire and rubber during hot pressing, the general method is to plate copper zinc alloy on the steel wire. Due to different uses, the metal plating is also different, commonly used metals are zinc, copper, silver, lead, chromium, nickel, black chromium, black nickel and so on.

(2) Protection measures for electroplated parts

Electroplating Most corrosive solutions are stable in organic acids and can maintain luster for a long time. However, the following situations will cause the plating to be corroded, and it is necessary to pay attention and take measures to protect it.

1, should prevent contact with salt, hydrochloric acid, bittern and other substances. Because the coating is easily soluble in the above substances, it is necessary to avoid contact with 84 disinfectant, bleaching powder, toilet cleaning and other substances.

2, motorcycles should not be stored in a place with gas, briquettes, and coal smoke. This is because carbon monoxide (CO) will cause the coating to produce gray-black network cracks and rust.

3, pay attention to the method of wiping. Usually in a week only need to wipe the motorcycle electroplating once neutral oil, such as sewing machine oil. Note that the dirt should be wiped with a soft cloth each time the oil is rubbed; After driving in rainy days, clean the dirt with clean water first; Then wipe with a soft cloth, and finally wipe with oil. Do not touch the oil on the paint and tire when rubbing, to prevent paint loss and tire aging. If there is water mist inside the meter and other coatings, it should be dried with a hair dryer and then wiped.

4, for the galvanized surface on the strip, due to its surface generated a layer of dark gray basic zinc carbonate film, can effectively prevent the internal metal from being corroded, so pay attention to do not have to wipe this layer of dark gray galvanized surface clean, polish, you can wipe some neutral oil to protect.

5, for the wipe of plastic electroplating parts, can only use a soft cloth dipped in water (warm water) wipe, can not be dipped in oil wipe, because it will destroy the coating of plastic electroplating parts.

6, for the exhaust pipe, fender, rim such plating parts, can not use wire brush dirt, because the wire brush brush will scratch the coating surface. Use clean water to loosen the dirt and dirt and then wipe it according to the above method. If the bubble is really not loose, use a wooden rod to gently descaling.
