Which is better, cold repair or hot repair of car tires?

Hot repair and cold repair are two different tire repair methods, which can be selected according to needs.

At present, the tire repair method on the market can be roughly divided into the following two categories: external repair method and internal repair method, and the internal method is subdivided into cold repair method (internal repair or paste repair), hot repair method (commonly known as fire repair), mushroom nail method and automatic sealant repair method.

The external repair method is a kind of emergency tire repair method, which is to stuff the adhesive strip into the breach and fill the tire breach by squeezing the rubber strip through the tire. Advantages: Simple operation.

Disadvantages: It can only be used as an emergency, and cannot be relied on for a long time, and if you want to continue to use the tire, you have to make internal repairs.

The following are the four common internal compensation methods on the market:

In the cold repair method, the tire is removed from the rim, the hole is found, the foreign matter around the hole is cleaned, and a special tire repair film is attached from the inside of the tire to complete the leak repair. This method.

Similar to the bicycle tire repair method, but the need for a special tire scraper and tire repair rubber to complete, with this method to repair the best in.

About 30 yuan. Advantages: Larger wounds can be repaired. Disadvantages: not durable, after a period of water immersion or high-speed driving.

, the repair area may leak again.

The hot patch method, also known as fire patching, is similar to the cold patch method above, which also attaches a special film to the hole, but with one more step.

The rip needs to be baked with a roaster until the film melts and bonds to the rip. Advantages: Very durable, no need to worry about wounds.

Repeated air leaks. Disadvantages: The technical requirements during construction are high, and professional machines must be used, otherwise the high heating temperature will cause secondary damage to the tires.

Injure. ps: Some people say that the current tires are vacuum tires, radial tires, and the tread has steel wires, which is no longer suitable for the fire repair that was popular in the past, and the authenticity.

There is no research yet. Mushroom nail patching, which is a popular method of repairing tires in recent times, is to use a rubber patch similar to a mushroom shape, from the inside of the tire.

Identify the loopholes in the noodles, put the mushroom roots out to the outside, and then cut off the excess part that is exposed, and glue the inner part with special glue.

Above. The mushroom root part can play an external tonic effect, while the mushroom leaf part is equivalent to the internal tonic effect. The ** patched with this method is in.

About 100-200 yuan. Advantages: The tire repair effect is very good. Cons: More expensive than the general method.

Automatic sealant repair method: This method is an emergency tire repair method in the case of no obvious breach, which is to polymer polymerization.

The compound is injected into the inside of the tire, and the polymer is adhered to the inside of the tire by the heat generated during the tire's driving.

role. Changan Ford S-Max Max is equipped with such an automatic sealant, and such a set of automatic sealant ** from 800-

2,000 yuan. Advantages: easy to operate, read the manual will use. Disadvantages: It is only a temporary repair, and the breach cannot be made if it is too large.

with, the purchase ** is very high.

Generally speaking, the repair method of bad tires can be roughly divided into three types according to the degree of tire damage: cold repair (internal repair or paste repair), hot repair (commonly known as fire repair) and rubber strip method.

The so-called cold repair is to remove the injured tire from the rim, find the wound, clean the foreign body at the wound, and paste a special tire repair rubber from the inner layer of the tire to complete the leakage. In fact, this method is similar to the tire repair method of bicycles, but it requires a special tire scraper and tire repair rubber to complete. The advantage is that it can repair large wounds, but the disadvantage is that it is not durable enough, and after a period of flooding or high-speed driving, the repair site is likely to leak again.

Hot supplement, heat repair (commonly known as fire supplement) is the most thorough tire repair measure. Heat repair also involves removing the tire from the rim and attaching a special raw film to the wound. The wound is then baked with a roaster until the raw film fits perfectly to the tire.

The advantage of thermal repair is that it is very durable, and there is basically no need to worry about repeated air leaks at the wound.

Generally speaking, small holes, cold repairs, large heat repairs, patched up, on the highway, there is no problem, change the tires, that's because your wheels are worn, and changing them can extend the service life of the tires Because the wheels have an inclination angle, so the steering wheel can be back to the right There is a problem Look at it and continue to communicate.

Of course, it's hot patching, but the cost of cold patching is low and the speed is fast, so most of them are cold patching now.

Hello! Mushroom nail repair and patch cold repair are our recommended repair methods.

Mushroom nail repair: the inner liner and the carcass are repaired as a whole, and the carcass wire will not be eroded by water. It is a method of repairing tires as a whole, repairing the inner liner and carcass from the inside to the outside of the tires that can be repaired, which is the most professional tire repair method now;

Patch cold repair: repair the inner liner with patches to ensure that there is no air leakage, but the carcass is not repaired. The holes in the carcass can ingest water and corrode the steel wires of the tire.

It is recommended that you find a professional tire shop to inspect your tires and determine the most suitable repair method.

It is not recommended to use heat repair, and tires as rubber products need to avoid high temperature damage to the carcass structure.

It's hard to say, it depends on the situation, and the details are as follows:

1. Cold repair, that is, a special tire repair film is pasted from the inside of the tire to complete the leakage. Hot repair, one more step than cold repair, is to use a baking machine to bake the breach until the film melts and then bonds with the tear. From the perspective of the process alone, it seems that hot compensation is more reliable and durable than cold repair;

2. So whether the tire is better to be hot or cold, for private cars, the tire is relatively thin, and the degree of heating by the method of heat repair is difficult to control, which may damage the tire;

3. However, it is better for trucks to make up for heat, the tires are thicker, and they have to bear weight and run long distances for a long time.
