ContiSeal？ Self-repairing tire is a new product jointly developed with Buick. This tire is definitely a black technology tire. ContiSeal？ The main function of self-repairing tire is to avoid tire leakage or puncture when the tire tread is punctured by foreign matter. And the horse brand ContiSeal? The working principle of self-repairing tire is different from that of popular explosion-proof tire at present. Although the results are similar, the working principle is completely different.
Here, let's talk about science first, and introduce explosion-proof tires and self-repairing tires respectively.
The scientific name of explosion-proof tire is "run-flat tire". The reason why the explosion-proof tire will not collapse after deflation is mainly because the thickened rubber sidewall can support the weight of the vehicle even if the air pressure is lost, and will not cause serious deformation. Therefore, the puncture will not seriously affect the driving of the vehicle, and even the owner may not feel it. The differences from traditional tires include explosion-proof characteristics, reinforced side walls, additional valve strips and high heat-resistant synthetic rubber materials. In the case of explosion-proof tires, the vehicle can still travel at a speed of 80 kilometers per hour.
And this Motor * * * jointly developed by Mapai Tire and Buick Automobile? Self-repairing tires mainly rely on the name "ContiSeal?" This synthetic adhesive sealing layer is also the origin of the name of self-repairing tire. ContiSeal is a mixture of butyl rubber, different polymers and fillers, which can be closely attached to the inner liner of tire without affecting the normal performance of tire. The adhesive sealing layer has air tightness, strong viscosity and balanced fluidity. When a foreign body with a diameter less than 5 mm pierces the tread, the sealing layer can quickly creep and wrap the foreign body, and its shape can be adjusted according to the shape of the foreign body, so as to quickly close the perforation and avoid the change of tire pressure. Its strong viscosity can ensure that the coating will not shift even when the tire is driving at high speed, and the sealing layer will flow to the damaged part when removing foreign objects, thus realizing the self-repair function. In addition, the adhesive sealing layer has a service life as long as 10 years.
When the tire is punctured by a foreign body with a diameter of less than 5 mm (the value of 5 mm is mainly set according to the maximum diameter of common nails in China), ContiSeal? The special adhesive sealing layer on the inner wall of the self-repairing tire can seal the puncture immediately, reduce the risk of tire leakage and puncture, and avoid being forced to stop for inspection or replacement during driving.
In view of the changeable climate and complicated road conditions in China, Buick GL8? Avenir, the Avia family launched Contisil? The applicability of self-repairing tire was deeply tested. Among them, the thickness of tire rubber layer is optimized according to the nail size in the domestic market. The road test covers all road conditions such as high-speed, towns and mountain roads, and the durability test is carried out under extreme working conditions, from Heihe at MINUS 30 degrees to Turpan and Condisil at MINUS 55 degrees. The air tightness, strong viscosity and balanced fluidity of self-repairing tires have all passed strict verification. In the winter test, the vehicle tires can support the maximum speed of 100km/h after inserting six nails, and continue to drive for more than 800km.
In addition, in the introduction of ContiSeal equipped with tires? At the same time of technology, Buick GL8? Avenir Avia family insists on the consistent pursuit of driving comfort, equipped with horse brand CC6 tires focusing on comfort and quiet performance. The tire adopts a unique "silent cabin" design. Based on the principle of "Helmholtz oscillator", sound waves pass through the silent cabin, eliminating noise frequency and blocking noise propagation. The application of frequency conversion noise reducer cuts the loud wave into small sound waves to realize sound absorption and noise reduction. At the same time, the tire tread pattern is upgraded synchronously, which not only improves the quiet and comfortable performance, but also further optimizes the wet drainage performance of the tire and ensures the handling performance.
In order to better display the horse brand ContiSeal? Since the strength of the self-repairing tire, we not only saw the cross section of this tire with our own eyes, but also demonstrated that it is equipped with ContiSeal? Buick GL8 with self-repairing tires? Avenir can still drive normally after driving nails, and the tire pressure has hardly changed. More interestingly, we can see that after the nail was crushed by the tire, because the nail was fixed on the ground, the nail was not taken away by the tire, and the tire left a little ContiSeal on the tip of the nail. Viscous substance.
In addition, according to the official staff at the scene, ContiSeal? The price of self-repairing tires is not much more expensive than that of non-self-repairing tires of the same brand. The price difference should be around 300-500 yuan. ContiSeal？ The price-performance ratio of self-repairing tires is still very beautiful; Also, if you find that the tire is pricked by a nail, you should deal with it in time. You can go to a shop authorized by Mapai Tire to repair it. At present, all authorized shops of continental tire in China have completed the maintenance of continental seal. Training of self-repairing tires.
After all, even though the horse brand ContiSeal? Self-repairing tires have a passively triggered black technology, but ContiSeal? The emergence of self-repairing tires also shows people another way to deal with tire accidents, and the biggest advantage of this black technology is that even after tire accidents, tires can continue to be used smoothly and safely, especially when time is urgent, tires cannot be replaced temporarily or there is no suitable place to repair them. The ability to work continuously for a long time is very satisfactory. Perhaps in the future, self-repairing tires will gradually become an essential function when many car owners choose tires first.
