Because the solid tire carcass is made of all rubber, the puncture resistance of the tire is ensured to the greatest extent, and the hidden danger of tire puncture during the load-bearing operation of industrial vehicles and in the harsh working environment is fundamentally eliminated. The load-deformation of solid tires is small, and the running stability is good. Because of its puncture resistance and tear resistance, it does not need to be inflated. It avoids the heavy labor of frequent tire replacement and can improve the utilization rate and work efficiency of the vehicle. It has high efficiency at low speeds. In the running vehicle, solid tires can completely replace pneumatic tires. Moreover, the wear resistance and puncture resistance are relatively good, and it can adapt to harsh environments. However, even so, some problems will occur during long-term use, such as falling blocks, when the tires are exposed to grease, When acid-base substances are corroded and exposed to high temperature for a long time, the physical and chemical properties of the tire will change, the load-bearing capacity will be greatly reduced, and the tire will burst easily during use. In addition, tires that have been corroded by oil may peel off the air-sealing layer, a small area of rubber at the tire mouth, and the carcass cord and rubber may peel off. Since the patch cannot be compatible with the oil-containing rubber, even if the tire damage is small, the possibility of repair is lost. Partially lumped off the rubber surface
reason:
(1) The mold is not opened in time after the vulcanization time is up, resulting in excessive sulfur and aging.
(2) Uneven mixing and heating of the rubber compound.
(3) Insufficient sulfur caused by poor heat preservation of the tire embryo and temperature fluctuation of the vulcanizer.
(4) The use environment is poor and is cut by external force.
(5) The use environment is corroded by chemicals.
