The role of PVC conveyor belt in underground coal mines is very important, because there are many risks of fire and explosion in the coal mine environment, and PVC conveyor belt can effectively reduce these risks. The belt body of PVC conveyor belt adopts high-strength, low-extension, high-quality polyester filaments in the longitudinal direction, and nylon filaments with high-strength and moderate modulus in the transverse direction. It has excellent flame-retardant and electrostatic conductivity. It also has the advantages of high strength, small elongation, light belt body, non-delamination of the belt body, impact resistance, tear resistance, and good groove formation of the belt body.

Maintenance method of PVC conveyor belt:

1. During transportation and storage, PVC conveyor belt should be kept clean, avoid direct sunlight and rain and snow, prevent contact with acids, alkalis, oils, organic solvents and other substances that affect the quality of rubber, and stay 1 meter away from the heating device.

2. When PVC conveyor belt is stored, the temperature in the warehouse is best kept between minus 15℃ and 40℃ above zero, and the relative humidity is best kept between 50-80%.

3. PVC conveyor belt should be placed in rolls during storage, not folded, and flipped once every season during storage.

4. The operating speed of PVC conveyor belt should not be greater than 5 meters/second. Low-speed transportation should be used as much as possible when transporting materials with large blocks and high wear resistance and when using fixed plow-type unloading devices. Exceeding the specified speed may affect the service life of the conveyor belt.

5. In order to reduce the impact and wear of the material on the PVC conveyor belt, the feeding direction is best to follow the direction of operation of the conveyor belt. The gap between the material falling to the conveyor belt should be minimized, and the feeding port should avoid the drum or directly above the roller. The receiving section of the conveyor belt should shorten the spacing of the rollers and take cushioning measures. In order to prevent scratching the conveyor belt, it is best to use rubber sheets of moderate hardness for the contact parts of the retaining device, scraper cleaning device and unloading device with the conveyor belt.

6. During the use of the conveyor belt, it is necessary to avoid the situation where the roller is covered by the material and the rotation is not good. It is necessary to prevent the leaking material from getting stuck between the roller and the conveyor belt. Pay attention to the lubrication of the movable part, but do not oil the conveyor belt.

7. If it is found that the PVC conveyor belt has deviated, measures should be taken to correct it in time.

8. If local damage to the PVC conveyor belt is found, it should be repaired in time to prevent the damage from expanding.

9. When using PVC conveyor belt, avoid the tape from being blocked by racks, pillars or bulk materials to prevent the conveyor belt from being broken and torn.
