Maintenance of Motorcycle Exterior Plastic Parts

Most of the motorcycle outer covering parts are made of ABS plastic products (especially scooters), which are beautiful and exude a strong modern atmosphere. However, after some motorcycles have been used for a long time, the paint film on the outer surfaces that are directly exposed to strong light often cracks (such as the head of the scooter, the upper part and both sides of the rear trunk, etc.). The main factors affecting the cracking of the paint film of ABS plastic products are improper selection of casting molding process parameters, lack of strict treatment before painting, and improper use. However, during use, preventive measures should also be taken for maintenance.

The winter temperature in most parts of areas is below 0℃, the temperature in some northern regions is -20℃, and the lowest temperature in some areas is -35℃. When a motorcycle is used under low temperature conditions, it is easy to cause difficulty in starting the engine, increase fuel consumption, and increase wear of parts. If the maintenance is not done properly, it will also cause great damage to the outer covering of the motorcycle. If the motorcycle is parked in the open air below 0℃ for a long time, cracks will occur throughout the depth of the ABS plastic parts, and below -40℃, it will be completely brittle. Therefore, motorcycles should be stored indoors as much as possible. If there is no condition to store them outdoors, prefabricated boards should be laid to prevent moisture from invading. It is best to put on a motorcycle cover to keep warm. It is also necessary to take off the motorcycle cover when it is sunny to drive away moisture.

In most parts of the world, the sun is strong in summer, and the temperature on the road at noon is as high as 40-50℃. ABS plastic products are prone to aging and hardening and brittle under the strong sunlight, strong ultraviolet rays and high heat, and severe cracking occurs. Therefore, it is necessary to avoid driving at noon as much as possible. When not using motorcycles, they should be stored indoors or under the shade of trees as much as possible. Motorcycles must not be parked in strong sunlight for a long time, which will cause the paint film to dry out too much and crack, and the paint film will fade and age due to the effect of ultraviolet rays.

In addition, be careful not to place the motorcycle in high temperature places such as stoves, resistance furnaces and open flames. Remember not to touch, scratch or press the paint surface with hard objects. Because the paint film will be deformed by tension after being touched and pressed, it is easy to cause cracking. Avoid long-term rain. Long-term exposure to rain will cause the varnish to swell, age and fall off, leaving a "painted face". After driving in the rain, it should be cleaned in time; when parking the vehicle, it should be placed in a shaded place that can avoid rain.

Strictly prevent oil pollution. The paint itself is an oil-soluble compound. Although the paint film of the ABS outer covering has a certain oil resistance, it will also dissolve over time. Therefore, after refueling or spilling oil, it should be wiped off in time and not left alone for a long time. The fuel tank cap must be tightly sealed to prevent long-term gasoline overflow from causing local paint film aging and discoloration on the surface of the fuel tank and cracking of the paint film of the ABS plastic decorative parts at the bottom of the mailbox.

When scrubbing the vehicle, be careful not to use gasoline, kerosene, diesel and various corrosive detergents to clean the paint surface of ABS plastic products. Always keep the surface of the ABS outer covering clean, and remember to wipe the sludge directly with a cloth, because the mud that falls on the paint film becomes an "abrasive" when wiping with a dry cloth, causing the outer surface of the paint film to lose its luster or crack. The best way is to rinse with water and wipe it dry in time. The cloth should be soft knitted cloth or cotton yarn. Car wax should be applied once a week. The role of wax is not only to make the paint film bright, but more importantly, it can prevent the paint film from aging and cracking, and maintain gloss and flexibility. Do not use any non-car wax. Due to the different composition of the paint film, the chemical composition of the wax is also different. Improper use will have the opposite effect.
