An abnormal sound is a relatively common mechanical fault of an automobile, in which a driver of the automobile can hear a muffled or sharp sound from an engine or a muffled sound from other parts due to abnormal friction, and the abnormal sound may occur alternately at a certain frequency or interval or may not occur intermittently at any regular time.
According to statistics, about 70% of automobile mechanical faults show certain abnormal sound, so that the automobile mechanical faults are diagnosed very practically by an audible method, along with the prolonging of the automobile service time and the acceleration of the abrasion of mechanical parts, when the automobile is braked and works, the abnormal sound is often generated during the work due to the fact that the gaps between the parts are increased, whether the automobile rotates in balance can be judged by hearing the abnormal sound of the automobile, and the fault position can be basically judged by judging the characteristics of the abnormal sound when the abnormal sound occurs, such as whether the abnormal sound is continuous, whether the abnormal sound is regular, whether the abnormal sound occurs intermittently and the like.
Generally, abnormal noise occurs in various parts such as a channel of a glass of an automobile, a door frame of an automobile, a trunk of an automobile, or a sunroof of an automobile. In order to solve the abnormal sound, a common solution is to fill the gap with a plastic or rubber sealing strip or sponge strip to reduce the abnormal sound of the automobile. However, the reduction is not equal to the elimination. In the process of automobile driving, the dynamic abnormal sound still occurs, and the problem cannot be better solved only by the sealing strip or the sponge strip.
At present, the flocking layer is considered as the wear-resistant coating of the sealing strip, but the contact between the flocking layer and the automobile window glass positioned on the flocking layer is still not tight enough, and particularly, the vibration of the automobile window glass in a lifting state still makes the automobile generate abnormal sound during the running process of the automobile.
Disclosure of Invention
The reason for this is that the flocked nap layer has no good adhesive force and wear resistance, so that the flocked nap layer cannot resist the vibration of the automobile window glass in the lifting state during the contact process with the automobile window glass, so that the automobile window glass generates frictional sliding with the flocked nap layer during the lifting vibration process, and abnormal sound is generated accordingly.
Electrostatic flocking is a process which utilizes the physical characteristics that like charges repel each other and opposite charges attract each other to make the fluff take negative charges, and the object to be flocked is placed under the condition of zero potential or grounding, and the fluff is attracted by the flocked object with different potential and vertically accelerated to fly to the surface of the flocked object.
