Industrial solid tire manufacturers talk about the causes of local block shedding on the surface
The solid tire body is made of full rubber, which ensures the puncture resistance of the tire to a greater extent, and fundamentally eliminates the hidden danger of tire puncture in the process of carrying and running industrial vehicles and in the harsh working environment. The solid tire has small load deformation and good running stability. Because of its puncture resistance and tear resistance, it does not need to be inflated, which avoids the heavy labor of frequent tire repair and replacement, and can improve the use rate and working efficiency of the vehicle. In low-speed and high-efficiency running vehicles, the solid tire can completely replace the pneumatic tire. It also has good wear resistance, stab resistance and other properties, and can adapt well to harsh environment. However, even so, some problems will occur during long time use, such as falling blocks,

When the tire is corroded by grease, acid and alkali substances and subjected to high temperature for a long time, the physical and chemical properties of the tire will change, the bearing capacity will be greatly reduced, and the tire is also easy to burst in use. In addition, the tire corroded by oil will have blocky peeling of the sealing layer, small area of rubber falling off at the tire mouth, and separation of tire cord and rubber. Because the patch cannot be compatible with the oil-containing rubber, even if the damage to the tire is small, it will lose the possibility of repair.
Reasons for local lumpy falling off of rubber surface:
(1) The mold was not opened in time after the curing time, resulting in excessive sulfur and aging.
(2) Uneven mixing and heat mixing of rubber.
(3) Poor heat preservation of the embryo and temperature fluctuation of the curing press cause sulfur deficiency.
(4) Cut by external force due to poor use environment.
(5) The use environment is corroded by chemicals.
