Matters needing attention in the use of automatic tire repair liquid

● The role of tire repair liquid Tire repair liquid is an emergency tire repair product, which is used when the tire is punctured and the maintenance conditions are temporarily unavailable. The advantage is that it is simple and fast, without replacing the spare tire and using a jack, and it can automatically inflate the tire, and then you can drive to the repair shop normally. At present, most models are still equipped with conventional spare tires, and only a few models cancel the spare tire assembly due to lack of air (except some models equipped with explosion-proof tires) and use tire repair liquid instead. ● Principle of tire repair liquid: tire repair liquid is a synthetic polymer compound and a white foam liquid. These tire patching solutions are stored in compressed air tanks and injected into tires through valves when in use. At the same time, the pressure of the compressed air tank is used to inject liquid into the tire while inflating it. After driving, the tire repair liquid in the tire covers the inner side of the tire evenly under the action of centrifugal force, and forms a sealing film on the inner surface of the tire, thus achieving the effect of tire repair. ● Types of tire repair fluids on the market/types of our experiments. There are all kinds of propaganda about tire-patching liquid on the Internet. Through investigation, we found that there are two main kinds of mainstream tire repair liquid: one is ordinary bottled liquid, which only has tire repair function and no automatic inflation function, and needs to be used with air pump. Some original models are equipped with tire repair liquid with a small air pump; The other is the more common automatic inflation tire repair liquid, which claims that tire repair and inflation can be integrated without jack, tire and air pump. This has become a product that many car owners are interested in, and our experiments are also aimed at this kind of products. ● How to use tire repair liquid? Despite the rhetoric, we always have doubts about the effect of automatic tire repair liquid. So can a bottle of tire repair liquid achieve such a magical tire repair effect? Not much to say, buy some bottles. We simulated several common puncture situations and introduced them to you with actual performance. Case 1: the tire is punctured/the nail is not pulled out/the tire is seriously leaking. Imagine that when we travel by car, we find that the tire is flat, and when we get off the bus, we find that the tire is punctured. There is no repair shop around, no one knows when the nail went in, and no one knows how long the residual gas in the tire can last. At this time, my heart must be very uneasy &; Hellip & ampHellip: We simulated this scene and replaced our test car with a tire punctured by a nail. At this time, the nail was not pulled out and the tire was almost completely flat. Measure tire pressure. At this time, the tire pressure was only 0.3bar, and we began to repair and inflate the tire with automatic inflation tire repair liquid. According to the instructions in the manual, we should first hold the compressed gas tank in our hands and shake it evenly for about 1 minute. Then lift the outer conduit, and the interface is butted with the tire valve. Tear off a ring next to the bottle switch, and turn the switch to the on position, and the tire repair liquid will automatically start working. It can be seen from the transparent conduit that the tire patching liquid will soon fill the liquid in the compressed air tank into the tire, and the deflated tire will obviously start to inflate and rise. The whole process is very rapid and can be observed with the naked eye.
