How to replace the car wiper is the knowledge that many of our drivers and friends need to understand. The windshield wiper is an important accessory installed on the windshield, and its function is to remove the rain, snow and dust that obstruct the vision on the windshield. 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 rainy days is accompanied by great 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, reduces the contact area between raindrops and the glass surface, and controls the refraction of light generated by raindrops. And let the raindrops achieve the effect of easy sliding. Compared with the current natural rubber windshield wipers, this ensures the sight line and ensures the safety of the operation on heavy rainfall days. (Silicone wipers designed for safe driving)

2. Silicone wipers have super durability. This is because the composition of silica gel is better than natural rubber in terms of heat resistance, UV resistance, ozone resistance, and abrasion resistance. Therefore, the silicone wiper can maintain the initial rain effect for a long time. (Exercising the super durability and high wiping performance of good wipers)

3. The silicone wiper will never shake. Because of the characteristics of silica gel and the coating of the newly developed anti-friction agent, it is more stable and less prone to jitter. Regardless of the flat glass or curved glass that has been treated with the water repellent effect, even if the resistance is large, it will not produce jitter.

 

Rubber wiper

 

1. The deformation movement of rubber molecules cannot be completed instantaneously, because the attraction between molecules must be overcome by the vibrational energy of atoms. If the temperature decreases, these vibrations become less active and cannot quickly destroy the attraction between molecules. Therefore, the deformation is slow. At very low temperatures, the vibration energy is not enough to overcome the attractive force, and the rubber becomes a hard solid.

2. If the temperature is constant and the speed of deformation increases, it can also produce the same effect as lowering the temperature. In the case of extremely high deformation speed, the rubber molecules do not have time to rearrange and will appear as hard solids.

3. The molecular chain of rubber materials will be slowly destroyed under stress, resulting in "creep", that is, the deformation gradually increases. When the deformation force is removed, this creep will form a small irreversible deformation called "permanent deformation".
