Sometimes the conveyor belt
will always age before the original service life, and many people do not understand the reasons. The following Xiaobian will introduce the specific reasons for the aging of the conveyor belt.
1, O2. Rubber is easy to have a chain reaction of free radicals with oxygen atoms, and the conveyor belt mainly uses rubber as raw material, so oxidation reaction is one of the reasons for the aging of the conveyor belt.
2, O3. Ozone in the atmosphere is also one of the reasons leading to the aging of the conveyor belt. The combination of oxygen atoms in ozone is more unstable than that of oxygen, so the oxidation reaction between ozone and the conveyor belt will also occur to make the conveyor belt rapidly aging.
3. Temperature. High temperature can increase the activated molecules in the rubber, so that the rubber is more easily oxidized with external substances, resulting in faster aging of rubber.
4, the light. Light conveys light energy, which, like heat, provides molecular activation energy. The shorter The light, The greater The energy. Among them, ultraviolet light, which belongs to invisible light, has greater destructive ability to rubber, which is The important factor for rubber aging under light.
5. Mechanical action. Under the daily operation of the conveyor belt, the conveyor belt and idler are easily subjected to different wear and tear. In the process of friction, energy will be generated, which will cause the oxidation reaction of rubber and lead to the aging of rubber.
6. Humidity. Water can dissolve the water-soluble substances contained in rubber, and this part of the substances will dissolve with the degree of rubber immersion, deepening the damage to rubber.
