Maintenance and use of car wipers[汽车修理知识]

Driving on rainy days,carWiperIt is an important tool to maintain a good line of sight.
The basic structure of the wiper blade is a steel wire and a rubber strip. The elastic steel wire with a certain curvature not only supports the rubber strip, but also makes the wiper parts close to the glass surface. The rubber used in the manufacture of wipers is also specially treated. It not only has sufficient elasticity, toughness and anti-aging properties, but also has a layer of graphite on the surface. It is this layer of graphite that makes the wiper slide smoothly on the glass.
Some people think that the wiper strip only needs to be replaced when it cracks. In fact, there is a thin layer of graphite on the wiper strip, which mainly plays a role of lubrication. When this layer of graphite wears out, the wiper will jump on the glass, and the rubber strip needs to be replaced. If you don’t wait for the rubber strip to be damaged before replacing it, the wire or bracket of the wiper will be ground directly to the glass, which will not be worth the gain.
