1. Material problem: the material of the decorative cover may be improperly selected, which is not resistant to high temperature or easy to corrode, leading to decay.
2. Environmental problems: harsh environments such as high temperature, humidity and dust will accelerate the aging and corrosion of decorative covers.
3. Improper maintenance: If it is not cleaned and maintained for a long time, dust and dirt will accumulate on the decorative cover, accelerating the aging and corrosion of the decorative cover.
4. Design problem: Improper design of the decorative cover will make the car vulnerable to wind and resistance during driving, thus accelerating wear and aging.
The above are the reasons that may lead to the easy decay of the upper decorative cover of the room-melting engine, which need to be analyzed and solved according to the specific situation.
