1. The Most Primitive Rubber Seal String Method
Puncture the damaged tire with a special insert tool, and then fill the damaged tire with a rubber seal string. After the glue has solidified, inflate the tire and apply soapy water around the rubber strip to check for air leaks. At last, use a knife to cut off the rubber strip that exposed the outer part of the tire.
The biggest advantage of this method is that it is simple to operate and low in cost, and it can be repaired directly on the unloaded tire without having to use the tire raking machine.
At best it can be regarded as an emergency remedy, because it is repaired from the outside, so the air tightness and firmness cannot be guaranteed. It is easy to relapse and cause safety hazards after a long time.
2. Hot Patching
This kind of tire repair method looks very solid and reliable, but in fact the effect is not ideal.
In this way, the damaged area of the tire must be cleaned up, and sometimes a tool such as a file is used to polish it, and then the gray glue is strongly attached to the internal wound surface. The external wounds are filled with vulcanized rubber, and finally tightened with a vulcanizer and vulcanized at a high temperature. After baking until the raw film is fully attached to the tire, it is finished.
This tyre repair method actually evolved from the first tyre repair method. After heat treatment, the air tightness is better and stronger than the first one.
However, its quality is closely related to the technology of the tire repairer, because it is not easy to master the “fire”. If it is not mastered, the internal structure of the tire may be damaged and there is a high safety risk.
This method is a bit like a bicycle tire repair. The tire needs to be removed from the wheel hub. If the wound is small and difficult to detect, soap bubbles should be applied to locate it. After finding the location, polish it.
After polishing, apply vulcanizing agent evenly on the polished area. Wait for the vulcanizing agent to become viscous before attaching the patch. Professional stores will use a roller to moderately press the patch. Ordinary stores usually use a hammer to hit the patch. Apply sealant around the patch.
First of all, this tire repair method is simple and efficient, so many tire shops use this tire repair method. At the same time, the price of this type of tyre repair is very cheap, and the price is linked to the tyre repair patch. The quality of the repair patch is more expensive, and the copycat is cheaper.
The disadvantage is that if a low-quality tire patch is used, it will gradually degummed and leak air after a long time. If the hole is large and the strength of the tire patch is insufficient, it may suddenly fail.
4. Mushroom Patching
The mushroom nail sounds cute, but its performance is not cute at all. This tire repair method is also emerging in China, and it is not very common.
The operation steps of the mushroom nail are roughly similar to the normal cold patch, but it is not a film attached to it, but a rubber nail that nails a mushroom head. First, drill the “root” of the mushroom nail from the inside of the tire at the correct angle to the perforation, lightly sand it, and remove the sanding dust.
Then squeeze a small amount of vulcanized rubber into the drilled hole and the polished area and leave it for 3-5 minutes. Use pliers to remove the handle of the mushroom nail from the outside of the tire, and pull it out from the nail hole. Stop when the root of the mushroom nail fits the tire inner liner. The subsequent steps are similar to the patch method, using a roller to roll the patch from the inside to the outside to tightly reinforce it. It may be difficult to use a hammer because it has a root to withstand it, so it is used less. Finally, only need to nail the excess handle on the mushroom and cut it off with a tool.
* Advantages and Disadvantages
This tire repair method has no obvious shortcomings. It can not only repair the damaged area on the inner side of the tire, but also fill the damaged area of the tire carcass through the bonding of the root and the tire, so it is very firm and reliable. At present, the price of this kind of tire repair is around 80 yuan to 120 yuan, relatively speaking, the quality will be more guaranteed.
5. Aerosol Tire Inflator
Tire sealer and inflator is relatively new. After shaking the can, spray it directly into the valve of the tire. The tire repair fluid will flow directly to the gap with the leaking airflow to fill the loopholes by itself.
The biggest advantage of this tyre repair method is that it is convenient and simple, and there is no need to unload the tyre. The old man and the old lady did not have any pressure to operate.
It can only be used as an emergency measure. It is best to find a closer tire shop for thorough repair after repairing.
