Factors affecting the life of polyurethane coated wheel

Factors affecting the life of polyurethane coated wheel
The chemical structure of the polyurethane material ensures that the tire has good stability. Since polyurethane is a completely reactive polymer, its molecules are connected by chemical bonds, thus avoiding the possibility of being oxidized or being filtered by other chemicals, thereby theoretically extending the life of the tire. The performance of polyurethane tires is good. The correct installation of polyurethane tires is directly related to the service life of the tires, especially when replacing new tires. Tires with different types and patterns must not be mixed at will due to the different actual size and load capacity of each polyurethane tire; the greater the load of the vehicle, the shorter the life of the tire, especially in the case of overload, which is more prominent. Polyurethane tires should be used within the large load corresponding to the specified load index; tires produced by regular tire manufacturers are marked with a speed class index. Polyurethane tires should be used within the high driving speed corresponding to the specified speed class index. The tire pressure of polyurethane tires is too low or too high, will affect the service life of the tire. If the tire pressure is too low, its radial deformation will increase, and the sidewalls will be deformed excessively, which will cause the crown and shoulders to wear. The temperature of the tire will increase, which will seriously reduce the service life of the tire. When the vehicle is running, the tire The tire temperature rises due to stretching, compression and friction. Excessive temperature is likely to aggravate tire wear and even blowout; if the vehicle is driven on sandy gravel or harsh road conditions for a long time, the service life of polyurethane tires will definitely be reduced. This is no exception for off-road vehicle tires; timely replacement of polyurethane tires, selection of appropriate tread patterns, daily maintenance, regular tire pressure checking, timely repair and frequent digging of stones and foreign bodies in the tread pattern all extend the life of the tire. Key factor.
