Ozone is an important factor that causes the rubber conveyor belt to age in the atmosphere.

Ozone is more active than oxygen, and its attack on conveyor belts, especially unsaturated rubber, is much more serious than oxygen.

After the oxygen molecules absorb short-wave ultraviolet light in the sunlight, the decomposed oxygen atoms recombine with the oxygen molecules to form ozone.

With the vertical flow of air, ozone comes to the surface of the earth, and the concentration of ozone gradually decreases from high altitude to the ground.

In addition, ozone is generated in the discharge place and near the motor, especially in the place where electric sparks are generated.

The concentration of ozone is different in different regions and different seasons.

Although the ozone concentration near the ground is very low, the harm it causes to rubber cannot be ignored;

Unsaturated rubber is easy to ozonation. Its appearance after ozonation are different from thermal oxygen aging.
