What is the difference between cold patching rubber and vulcanized rubber for automobile tire repair?

Vulcanization can be achieved in two ways. One is heating, that is, hot patching when patching tires; The other is chemical vulcanization at room temperature after adding vulcanizing agent, but please note that this is not the so-called &; Quot Cold Patch quot Because some cold patches use physical bonding, they can't play any role in repairing tires at all. The difference between normal temperature chemical vulcanization and cold patching is that it is different from the coating on the tire. Quot After the glue quot, the vulcanizing agent dries in the patch, while the cold patch needs a wet patch, and it won't stick when it dries. So rubber strip vulcanized on different tires, and it only blocked the hole by the viscosity of rubber strip itself. In foreign countries, this is only a temporary measure of DIY, allowing car owners to drive their cars to specialty stores without crushing and damaging tires. What about hot patching? Different vulcanization? Yes But what if the skeleton material in the tire is damaged? Tires are not balloons, as long as they don't leak, the damage of skeleton materials will bring the possibility of puncture! What's more, local heating of hot patching may lead to accelerated volatilization of additives in the heated tire, which may easily lead to local aging of the tire. At that time, the problem was unpredictable. For chemical vulcanization, it is best to use a patch with cord, such as Tektronix's CT patch, instead of a thin inner tube patch. Of course, even the inner tube patch can be repaired by specific heat, because the patch is preformed and its strength is definitely greater than that of hot repair. It is best to use Tektronix's integral plug.
