As we all know, when you use the car every day? A high-speed puncture is a very dangerous situation. Even if you don't drive on the highway, the tires will be punctured and leaked, which will affect the next trip or have great safety hazards. Mabai's self-repairing tire can solve this problem well. In fact, as early as two years ago, Ma Pai had already demonstrated this kind of tire, and it has been equipped on some models. This is the first time that Ma brand has been mounted on Buick models, and the high-end Buick GL8 Avia will bear the brunt.
This self-repairing tire of Ma brand is very different from the previous explosion-proof tire and belongs to a new generation of tires. The principles of the two are completely different. The previous explosion-proof tires can still run on the thick sidewall after being punctured. Even if there is no air, the distance is short, usually not more than 80 kilometers, and the speed is limited. The most important thing is that the thicker side wall affects the comfort and mute performance.
Ma brand self-repairing tire is coated with an adhesive sealing layer on the inner wall of the tire. When the tire is punctured by a foreign body with a diameter less than 5 mm, the adhesive sealing layer can immediately seal the punctured part, thus reducing the risk of tire leakage and puncture, so as to continue driving. This kind of tire can repair 80% of flat tires, and the mileage is far higher than that of explosion-proof tires. The tread is thicker and less deformed, which can effectively absorb the buffer of the road surface and improve the quiet and comfort. But there is nothing it can do if it encounters alien metal objects or tire puncture devices. But in any case, this technology still has an advantage over "anti-puncture tires".
At the scene, we conducted a puncture test on the tire. It can be seen that although the tire was punctured by a steel nail with a diameter of 5 mm, because the sealing layer was quickly sealed and there was no air leakage, the tire pressure did not change before and after the tire burst, and the vehicle could continue to drive safely. It should be noted that this kind of self-repairing tire also needs to be repaired afterwards, which is no different from ordinary tires.
At the same time, this sealing material, called ContiSeal, is a mixture of butyl rubber, different polymers and filling materials. It has air tightness, strong viscosity and balanced fluidity, and can be closely attached to the inner liner of the tire without affecting the normal performance of the tire, which is also the key technology of the tire. The adhesive sealing layer also has a long service life of 10 years, and it is not necessary to replace the tire until it is scrapped.
Another advantage is that GL8 Avia can repair the tires by being equipped with horse brand, and there is no need to prepare a spare tire, which effectively saves the interior space, reduces the counterweight of the whole vehicle and improves fuel economy.
We also tested the performance of this tire, because this tire of Ma brand adopts a unique "silent cabin" design, which eliminates noise frequency and blocks noise transmission by entering and leaving the silent cabin. At the same time, the large sound wave is cut into small sound waves by using frequency conversion noise reducer, so as to achieve the purpose of sound absorption and noise reduction. It is the adoption of these technologies that makes Buick GL8 Avia show superior comfort and quietness when we pass through asphalt roads, uneven roads, cement roads and other road conditions.
