With the rapid economic development, solid tires are widely used in transportation, and the recycling of waste tires has become an urgent problem to be solved. Under normal conditions, some tires can be retreaded and repaired, and then reused. However, more waste tires are recycled and reprocessed into other products.

    Tire rubber is recycled through processes such as cutting, crushing, and steam vulcanization. The rubber on the tire surface layer is peeled off, the embedded hair is removed, and the powder is processed into a recycled rubber material, which is then vulcanized to make a recycled rubber product. Due to the easy availability of raw materials, low cost, and good market demand for products, the processing and processing business of waste tires is booming. However, due to repeated processes, complicated production and short service life of the finished product, this is not a good solution, it is just to dispose of used tires. The method of using waste tires to directly process products is ideal, which not only has low cost, but also has the characteristics of tires. The internal warping structure is not damaged, and the embedded hair is strengthened. Therefore, the finished product has a long service life, and the direct production of rubber products from waste tires is worth promoting.

    In addition, solid tires have high durability in use due to the wear resistance, aging resistance, water resistance and shock absorption characteristics of the tire rubber. Therefore, the treatment of waste tires is mainly concentrated on rubber particles and rubber powder, which are widely used in modified asphalt, waterproof materials, rubber floor tiles or rubber tracks.

    The thick steel wire at the rim separated from the waste solid tire and the thin steel wire in the tire can also be used for reprocessing.
