How to replace the car wiper is what many of our driver friends need to know. The wiper is an important accessory mounted on the windshield. It is used to remove rain, snow and dust from the windshield that obstruct the view. Therefore, it plays an important role in driving safety. There are two types of wipers: rubber wipers and silicone wipers. What is the difference between rubber and silicone wipers?
Silicone wiper
1. Driving on a rainy day is accompanied by a very big danger. However, if a silicone wiper is used, the water repellency on the windshield makes it difficult for rainwater to adhere to the glass surface, reducing the contact area between the raindrop and the glass surface, and controlling the refraction of light generated by the raindrop. And let the raindrops achieve the effect of easy sliding. Compared with the current natural rubber wiper, this guarantees the line of sight and ensures the safe operation of a large rainfall day.

2. Silicone wipers have superior durability. This is because the composition of the silica gel is better than the natural rubber in heat resistance, ultraviolet resistance, ozone resistance, and abrasion resistance. Therefore, the silicone wiper can maintain the initial raining effect for a long time. (Using a good wiper for ultra-durability and high brushing performance)
3. silicone wiper will never produce jitter. Because of the properties of silica gel and the coating of newly developed antifriction agents, it is more stable and does not easily cause jitter. Whether it is a flat glass or curved glass that has been treated with a water-repellent effect, even if the resistance is large, there is no jitter.
Rubber wiper
1. The deformation motion of rubber molecules cannot be completed instantaneously, because the attraction between molecules must be overcome by the vibrational energy of the atom. If the temperature is lowered, these vibrations become less active and cannot cause the intermolecular attraction to be rapidly destroyed. Therefore, the deformation is slow. At very low temperatures, the vibration energy is not sufficient to overcome the attraction and the rubber becomes a hard solid.
2. If the temperature is constant and the speed of deformation increases, the same effect as lowering the temperature can be produced. In the case of extremely high deformation speeds, rubber molecules do not have time to rearrange, and they appear as hard solids.
3. the rubber material under the action of stress will be slowly destroyed, resulting in "creep", that is, the deformation gradually increased. When the deformation force is removed, the creep forms a small irreversible shape called "permanent deformation."
