Where is the Anti-Static Grounding Strip Installed on a Car?
1 Answers
Automotive anti-static grounding strips are installed on certain vehicles such as tanker trucks or those transporting hazardous materials. When these vehicles are in motion, actions like acceleration, deceleration, and bumping can cause the gasoline inside the tank to slosh around. The constant friction between the gasoline and the tank walls generates static electricity. If too much static electricity accumulates, it can become dangerous. Therefore, tanker trucks require anti-static grounding strips to safely discharge this static electricity. Regular household vehicles do not need such devices. Static electricity is a common phenomenon in daily life. For example, during winter when skin tends to be drier, touching metal objects can release static electricity, giving a person the sensation of being shocked. When different objects come into contact, the concentration and work function of charge carriers on their surfaces vary, causing these carriers to migrate from one surface to another. If the two objects are then separated, one will carry a positive charge while the other will have a negative charge. Static electricity is essentially a reaction that occurs when solids, liquids, or gases undergo friction, spraying, or sudden decomposition.
