A motorcycle is usually made up of thousands of parts, large and small. Electroplated parts are an important part of them. Motorcycle electroplated parts according to the plating material can be divided into two kinds of metal electroplated parts and plastic electroplated parts, such as handlebar, fender, rim, exhaust pipe, etc., belongs to the metal plating base parts; And scooter shell, instrument, trademark, model logo belongs to plastic plating base parts. If the electroplating of the motorcycle is kept intact, the vehicle will look brilliant. On the contrary, if the plating parts have rust, scratch, dent, the whole vehicle is ugly, and further affect the rider riding image. For example, some luxury imported motorcycles with large displacement, such as trademark and rusty exhaust pipes, can be troublesome (because these parts are very difficult to buy).
(a), the classification and characteristics of electroplating
The classification and characteristics of electroplating are mainly: electroplating can be divided into protective, decorative and functional three categories according to the use of functions.
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 steel parts.
2, protection - 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 or more, and some more. Such as motorcycle fender, ring, horn handlebar, exhaust pipe, etc.; This kind of coating in addition to look good, but also to prevent the main parts of the role of rust.
3, functional coating: this coating is usually applied to the friction surface of shaft parts, engine cylinder and piston ring, generally adopt the method of chrome plating to increase the wear resistance of the main parts.
4, other coating: when producing tires, in order to increase the bonding between steel wire and rubber in hot pressing, the general method is to coat copper and zinc alloy on the steel wire. Because of the use of different, plating metal is also different, commonly used metals zinc, copper, silver, lead, chromium, nickel, black chromium, black nickel and so on.
(2) Protection measures of electroplating parts
Electroplating of most corrosive solutions, in organic acids is stable, can maintain luster for a long time. But the following circumstances will make the electroplating corrosion, need to pay attention to and take measures to protect.
1, should prevent contact with salt, hydrochloric acid, bitter brine and other substances. Because the coating is easily dissolved in the above substances, so avoid contact with 84 disinfectant, bleaching powder, clean toilet and other substances.
2. Motorcycles should not be stored in places where there is gas, coal ball stove and soot. 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 on the motorcycle electroplating brush a neutral oil, such as sewing machine oil. Pay attention to each time the oil should be used to wipe the dirt with a soft cloth; After driving on rainy days, you should wipe the dirt with clean water first; Then wipe with a soft cloth and wipe with oil. Do not touch the paint surface and the tire when applying oil to prevent the loss of paint surface and tire aging. If there is water mist inside the instrument and other coatings, you should dry them with a hair dryer and then wipe them.
4. For the galvanized surface of the strip, because of the formation of a layer of dark gray alkaline zinc carbonate film on its surface, it can effectively prevent the corrosion of the internal metal. Therefore, it is necessary to wipe the dark gray galvanized surface and polish it, and some neutral oil can be wiped to protect it.
5, for the plastic electroplated parts of the wipe, can only use a soft cloth dipped in water (warm water) to wipe, can not dip the oil wipe, because that will destroy the coating of the plastic electroplated parts.
6, for exhaust pipe, fender, rim such plating parts, can not use steel brush to brush dirt, because the wire brush wire will scratch the surface of the coating. Apply clean water to loosen the dirt and then wipe it according to the above method. If it is true that the bubble does not loose the application of wood rod gently descaling.
